Corporate Process Service: A Complete Guide to Serving Business Entities

Corporate process service is the statutory mechanism by which courts acquire jurisdiction over business entities. It operates through an infrastructure that has no equivalent in individual service: a network of registered agents, registered offices, and Secretary of State fallback procedures created by state corporate law specifically to ensure that every business entity that enjoys the liability protections of the corporate form can reliably be reached by civil process. Understanding that infrastructure — which entities use it, how it works in each state, what the law requires at each step, and what the documentation must prove — is the foundation of effective corporate litigation. This page is the complete guide to that infrastructure. Each section covers one component of corporate process service and cross-links to the specialized pages in this cluster for practitioners who need depth on a specific issue.

What Is Corporate Process Service

Corporate process service is the delivery of legal process — a summons and complaint, subpoena, injunction, or other court-issued document — to a business entity in a manner that satisfies the constitutional and statutory requirements for valid service. The constitutional floor is established by Mullane v. Central Hanover Bank & Trust Co., 339 U.S. 306 (1950): service must be “reasonably calculated, under all the circumstances, to apprise interested parties of the pendency of the action.” For business entities, satisfying that standard requires compliance with the specific service methods authorized by statute — not just delivery to any person at any address associated with the company.

In federal court, Rule 4(h)(1)(B) of the Federal Rules of Civil Procedure governs corporate service: process must be delivered to an officer, managing or general agent, or any other agent authorized by appointment or law to receive service of process. The most important authorized-by-law agent is the registered agent — a person or entity that every domestic corporation, LLC, and limited partnership is required to designate with its state’s Secretary of State as the official recipient of legal process. State statutes create parallel requirements: CPLR 311(a)(1) in New York, Cal. Corp. Code § 416.10 in California, 8 Del. C. § 321 in Delaware. These statutes do not merely authorize registered agent service — they require that the entity maintain an agent specifically for this purpose.

The foundational legal principle that makes the registered agent system work is the “deemed service” doctrine: service delivered to a properly designated registered agent at the correct registered office constitutes service on the entity itself at the moment of delivery — regardless of when the entity’s officers or lawyers actually learn of the action. The entity cannot defeat service by claiming its registered agent failed to notify it promptly. For the complete constitutional and procedural analysis of how registered agent service satisfies due process, see our registered agent legal framework guide.

Who Needs Corporate Process Service

Corporate process service is required in any legal proceeding where one of the parties is a business entity. The range of practitioners who regularly need it is broader than the litigation attorney audience that most process service guides address.

Litigation attorneys are the primary users. A civil complaint against a corporate defendant must be served before the court can proceed; without valid service, the defendant has no obligation to respond and the action cannot move forward. For attorneys handling commercial disputes, breach of contract claims, employment litigation, personal injury cases with corporate defendants, and securities actions, corporate process service is a routine operational requirement — but one where errors have serious consequences. A defective service attempt does not pause the FRCP 4(m) 90-day clock. A motion to dismiss under FRCP 12(b)(5) based on insufficient service is one of the few procedural motions that can terminate an action before the merits are ever reached.

In-house counsel encounter corporate process service when serving counterparties in commercial disputes — contract enforcement, IP enforcement, vendor disputes, and competitive litigation. The challenge for in-house teams is often entity identification: a business relationship may have been conducted with a trade name or operating subsidiary, and the correct defendant for litigation purposes is the legal entity that signed the contract or holds the relevant asset.

Government agencies serve corporate entities in regulatory enforcement proceedings, tax collection matters, administrative hearings, and consent decree enforcement. Federal agencies operating under the Administrative Procedure Act and state agencies enforcing regulatory statutes have their own service requirements, but they generally interface with the same registered agent infrastructure that governs private civil litigation.

Individual litigants — consumer plaintiffs, employment claimants, landlord-tenant litigants — frequently find themselves needing to serve large corporate defendants. The registered agent system is the most reliable pathway for individual litigants who do not have the resources to investigate a corporation’s officer roster. For a complete breakdown of service methods organized by entity type, including sole proprietorships and general partnerships that do not have registered agents, see our guide to serving business entities.

The Corporate Service Process: Five Steps from Receipt to Affidavit

Corporate process service is not a single act — it is a five-step verification and delivery workflow. Each step has a specific purpose, and failures at any step can produce a defective service that survives initial delivery but fails under a motion to dismiss challenge months later.

Step 1 — Entity identification. Confirm the exact legal name of the entity to be served, its entity type (corporation, LLC, LP, etc.), its state of formation, and its current active/good-standing status with the Secretary of State. The entity name on the summons must match the registered legal name exactly — not a trade name, not an abbreviation, not a parent company’s name. “Corp.” vs. “Corporation” is a discrepancy that commercial registered agents’ intake staff will note; defense counsel will raise it if it can support a service challenge. Active status verification is equally essential: a dissolved or administratively defunct entity has no registered agent accepting service on its behalf.

Step 2 — Registered agent verification. Confirm the current registered agent identity and registered office address from the live Secretary of State database at the time of dispatch — not from the complaint caption, not from a prior affidavit of service on the same entity, not from a search engine result cached months earlier. Registered agents change on contract renewals, corporate restructurings, and agent resignations. The commercial agent’s office address on the SoS database is the operative address; if it conflicts with what the attorney’s file shows, the SoS database governs.

Step 3 — Document pre-check. Before dispatch, confirm that the entity name on the documents matches the entity name in the SoS database. Also confirm that the entity type on the documents is consistent with the correct service method: a complaint served on “Amazon.com” as a sole proprietorship would use the wrong service rules. For matters with multiple defendants — a parent entity and a subsidiary, or a corporation and its LLC operating arm — each entity must be verified independently. See our registered agent requirements guide for qualification standards and verification protocol.

Step 4 — Dispatch and delivery. The process server physically delivers the documents to the registered agent at the confirmed registered office address. For commercial registered agents — CT Corporation System, Corporation Service Company, NRAI — delivery is to an intake representative who issues a written receipt documenting the delivery. For individual registered agents, delivery is to the agent in person. The server confirms with the recipient that they are authorized to accept service on behalf of the named entity.

Step 5 — GPS-verified affidavit. The affidavit of service documents the entity’s exact legal name and agent designation, the recipient’s name and role, the documents served, the exact date and time, and GPS coordinates confirming the delivery location matches the registered office address on file. For commercial agent deliveries, the written intake receipt is referenced as corroborating evidence. For NYC five-borough services, the process server’s DCWP license number is documented. The affidavit is electronically returned to counsel the same day for time-sensitive matters.

Registered Agents: The Infrastructure of Corporate Service

The registered agent is not an optional convenience — it is a statutory requirement, and it is the primary mechanism through which corporate service works. Every corporation, LLC, limited partnership, and limited liability partnership formed in or qualified to do business in any U.S. state is required by the corporate statute of that state to maintain a registered agent with a registered office address within the state. This requirement exists because the entity needs a fixed, reliably accessible point where civil process can be delivered. Without it, a plaintiff would have no way to serve a corporation that chooses to be evasive.

There are two categories of registered agent. An individual registered agent is a person — typically an officer, director, or employee of the entity — who is a resident of the state and has a physical street address there. An individual agent works well for closely held corporations and single-state LLCs, but creates a fragility: if the individual resigns, relocates, or is unavailable, the entity may briefly have no valid agent on file. A commercial registered agent is an entity — CT Corporation System, Corporation Service Company (CSC), or National Registered Agents Inc. (NRAI) — that maintains staffed offices in all 50 states and provides registered agent services to corporate clients at scale. Commercial agents have dedicated intake staff, fixed business hours, and established procedures for receiving service, issuing receipts, and notifying the represented entity. For nationwide process service operations, knowing the current commercial agent office addresses in every state is foundational infrastructure.

The most important practical rule for process servers is that registered agent addresses go stale between annual report filings. Commercial agents relocate their offices as leases change; individual agents resign or move. The SoS database reflects the most recently filed agent information, which may be up to two years old in states with biennial reporting cycles. Our CT Corporation service guide documents current CT Corp office addresses and intake procedures across all 15 major states. For the full statutory and qualification framework governing who can serve as a registered agent, see our registered agent requirements guide.

Entity Types and Their Service Rules

The correct service method depends on the entity type. A service that works for a corporation may not work for an LLC, and a service that works for a limited partnership may not work for a general partnership. The entity-type determination is a threshold issue that precedes every other step in the corporate service workflow.

Corporations (domestic and foreign) are served through their registered agent under FRCP 4(h)(1)(B), CPLR 311(a)(1) in New York, Cal. Corp. Code § 416.10 in California, and the equivalent statute in every other state. A foreign corporation — one incorporated in another state but authorized to do business in the forum state — has a registered agent in the forum state and may also be served through its home-state registered agent. Both routes are typically valid; the choice depends on which agent address is more reliably current.

LLCs are served through their registered agent under the applicable LLC statute. The member-managed vs. manager-managed distinction matters when the registered agent is unavailable and backup service on an authorized member or manager is attempted. A member of a manager-managed LLC who has no management authority may not qualify as an authorized recipient for service purposes under some state LLC statutes.

Limited partnerships are served through their registered agent. The general partner of an LP is also a valid service recipient in most jurisdictions, because the general partner has management authority over the LP and is personally liable for its obligations — the functional equivalent of an officer for service purposes.

General partnerships have no formation filing and therefore no registered agent requirement. Service is made on a partner or the managing or general agent of the partnership under FRCP 4(h)(1)(B) or the state equivalent. The trade name problem is acute for general partnerships operating under a DBA: the named defendant should be the legal partnership, not just the trade name.

Sole proprietorships are not business entities in the legal sense — they are individuals operating under their own name or a trade name. Service is made on the individual under FRCP 4(e) (federal) or CPLR 308 (New York), not through registered agent procedures. The trade name alone is not a valid service recipient.

The entity-type analysis becomes particularly important when the defendant’s identity is unclear — when a plaintiff knows a trade name but not whether the underlying entity is a corporation, LLC, or sole proprietorship. For the complete entity-type-by-entity-type service reference, organized by business form and applicable statute, see our guide to serving business entities.

State-by-State Variation: Key Jurisdictions

Corporate service requirements are state-law creatures, and the differences between states matter operationally. The following covers the four jurisdictions that account for the largest share of corporate service engagements.

New York. New York’s registered agent system is structurally unique. Under NY BCL § 305 and NY LLCL § 301, the Secretary of State is the statutory registered agent of record for every domestic and foreign corporation and LLC registered in the state — by operation of law, without any separate appointment. Every entity that files in New York automatically has the DOS as its agent. Entities may additionally designate a private forwarding address for papers the DOS receives. Direct commercial agent service is also available: CT Corporation System at 28 Liberty Street, New York, NY 10005 receives service for entities that have designated CT Corp as their private agent. The CPLR 311(a)(1) officer/managing agent route and the NY SoS route are both regularly used. See our New York Secretary of State service guide for the full procedure.

Delaware. Delaware is the incorporation jurisdiction for the majority of U.S. public corporations and a large share of closely held entities. Under 8 Del. C. § 321, service on a Delaware corporation’s registered agent in Delaware constitutes valid service regardless of where the corporation operates. The dominant commercial agents maintain their Delaware offices at 1209 Orange Street, Wilmington (CT Corporation System / The Corporation Trust Company) and 251 Little Falls Drive, Wilmington (CSC). Delaware’s annual franchise tax report (due March 1) is the maintenance mechanism that keeps registered agent information current. Entities that fail to file lose good standing; extended failure results in void status under 8 Del. C. § 510. The Delaware SoS provides fallback service for void and dissolved entities under 8 Del. C. § 132. See our Delaware Secretary of State service guide.

New Jersey. New Jersey requires domestic and foreign corporations to maintain a registered agent under N.J.S.A. 14A:4-2. Service on the registered agent constitutes valid service. The New Jersey SoS provides fallback service under N.J.S.A. 14A:4-5 for entities that have lost their registered agent. See our New Jersey Secretary of State service guide.

California. Cal. Corp. Code § 416.10 governs service on domestic and foreign corporations. The agent must be a California resident (for individual agents) or a registered corporate agent listed with the California SoS (for commercial agents). CSC maintains its California office at 2710 Gateway Oaks Drive, Suite 150N, Sacramento, CA 95833. CT Corporation maintains its California office at 330 North Brand Boulevard, Suite 700, Glendale, CA 91203. The California Statement of Information (annual for corporations, biennial for LLCs) is the maintenance mechanism for agent information.

Federal court. FRCP 4(h)(1)(B) governs all corporate service in federal actions, supplemented by state law where the entity has no registered agent appointment or the action involves a state law claim. The FRCP 4(m) 90-day service deadline runs from the complaint filing date; failure to serve within that period without good cause shown can result in dismissal without prejudice — which, combined with a statute of limitations that has since run, effectively terminates the action. Every corporate service engagement should have FRCP 4(m) compliance built into its timeline from the moment the order is received.

International Corporate Service

Corporate litigation increasingly involves international entities: foreign corporations with U.S. operations, U.S. corporations with foreign subsidiaries, and multinational defendants where the appropriate legal entity is not immediately obvious. International corporate service adds a layer of complexity — treaty obligations, foreign court procedures, and translation requirements — but the fundamental analysis starts with the same entity identification questions that govern domestic service.

Foreign corporations with U.S. registered agents. A foreign corporation authorized to do business in any U.S. state must maintain a registered agent in that state — the same requirement that applies to domestic foreign corporations. Service on the U.S. registered agent is valid service on the foreign corporation under the law of the state where the agent is located, and that service is fully effective for U.S. court proceedings. This is the preferred route when available, because it eliminates the complexity and delay of international service procedures.

U.S. corporations with international subsidiaries. When a U.S. parent has been sued and the dispute actually involves a foreign subsidiary’s conduct, the entity identification problem requires careful analysis of which entity is the correct defendant. Serving the U.S. parent’s registered agent is valid, but if the foreign subsidiary is the appropriate party, the parent’s registered agent address may not be the right service target. Conversely, attempting to serve a foreign subsidiary through its home-country procedures when the U.S. parent is the correct defendant wastes time and may not produce valid service at all.

Hague Convention service. FRCP 4(f) governs international service. For foreign entities in Hague Convention signatory countries, service is made through the Central Authority of the foreign country, which processes requests and transmits service papers in accordance with local requirements. Hague service is specifically exempt from the FRCP 4(m) 90-day deadline — the clock does not run while international service is pending. For entities in non-signatory countries, service is effected through letters rogatory, bilateral treaty mechanisms, or other methods authorized by FRCP 4(f)(3) on court order. For the full analysis of multi-entity and international corporate service strategies — including the corporate family identification protocol, Hague Convention procedures, and same-day multi-state coordination — see our advanced corporate process service guide.

Common Challenges in Corporate Service and How to Overcome Them

Six challenges account for the majority of corporate service failures. Each is preventable with the right pre-dispatch protocol.

1. Entity misidentification. Serving “Amazon” when the correct defendant is “Amazon.com Services LLC” — or serving the parent when the operating subsidiary is the proper party — produces a service that cannot be cured without re-serving the correct entity. The solution is entity identification before any other step: confirm the exact legal name, entity type, and state of formation for every named defendant. For multi-entity corporate families — JPMorgan Chase & Co. vs. JPMorgan Chase Bank, N.A. vs. J.P. Morgan Securities LLC — the correct entity is a legal determination that should be confirmed with counsel before dispatch.

2. Stale registered agent addresses. Commercial agents relocate their offices; individual agents resign or move; SoS databases reflect the last-filed address, which may be up to two years old. The solution is live SoS database verification at the time of dispatch, cross-referenced against current knowledge of the commercial agent’s operating offices.

3. Commercial agent office access. Commercial registered agent offices have fixed intake hours — typically 8:00 AM to 5:00 PM on business days. A server dispatched at 4:50 PM to an office that closes at 5:00 PM has a narrow window; after hours, there is no service that day. Pre-confirmed office hours for every major commercial agent location in every target state are part of the dispatch infrastructure, not something to investigate on the day of service.

4. Multi-entity multi-state coordination. When multiple corporate defendants across multiple states must be served on a compressed timeline — parent and subsidiaries, co-defendants in different jurisdictions — parallel dispatch coordination is required. Each entity must be verified independently; each state’s registered agent must be confirmed; each server must be dispatched to arrive during business hours. Improvised same-day multi-state service is a common source of failures on one or more defendants.

5. Dissolved or defunct entities. Administrative dissolution strips an entity’s registered agent of the obligation to accept service on its behalf. Process served at a commercial agent address for a dissolved entity may be returned or refused. The solution is entity status verification before dispatch and SoS fallback service for dissolved entities under the applicable state statute.

6. Document name mismatch. “XYZ Corp.” vs. “XYZ Corporation” — or a trade name on the summons where the legal name should appear — is a discrepancy that commercial agent intake staff will note on the receipt and that defense counsel will use in a service challenge. The solution is document pre-check before dispatch: entity name on the papers must match the SoS registration exactly. For the complete advanced strategies treatment of all six challenges, including multi-jurisdiction coordination and international service, see our advanced corporate process service guide.

Speed, Deadlines, and Service Tiers

Corporate service timing is not simply a matter of how quickly a process server can dispatch — it is a function of which legal deadline is controlling and what the consequences of a late or defective service would be. Four deadline categories drive speed-tier selection in corporate service engagements.

Statute of limitations. In New York, CPLR 306-b gives a plaintiff 120 days from filing to complete service; if service is not made within that window, the action may be dismissed. In many states and in federal court, the limitations period is tolled by filing, but only if service is completed within the applicable service window. An action filed one day before the statute of limitations expires must be served within the service window or the limitations defense is available to the defendant.

FRCP 4(m) 90-day clock. In federal court, service must be completed within 90 days of filing the complaint. The clock runs from filing; it does not pause because the parties are in settlement discussions or because the plaintiff’s attorney has not yet retrieved the summons from the clerk’s office. The standard corporate service workflow — entity verification, agent confirmation, dispatch, delivery — must fit within whatever portion of the 90-day window remains when the service order is placed.

TRO and preliminary injunction hearings. A temporary restraining order or preliminary injunction hearing requires that the defendant be served before the hearing, or that the court find that service would be futile. A same-day service requirement with a next-morning hearing is among the most time-sensitive corporate service scenarios, and it requires not only fast dispatch but accurate service — a defective same-day service does not satisfy the notice requirement for an injunction hearing.

Discovery subpoenas. A corporate defendant or non-party subject to a document subpoena or deposition subpoena has specific response deadlines running from service. The return date on the subpoena determines how far in advance of the scheduled deposition or document production service must be completed. Subpoena service on a corporate registered agent follows the same verification and delivery workflow as complaint service.

The service tier appropriate to each scenario: Routine ($100–$150, first attempt within 3–7 business days) when no active deadline requires acceleration. Rush ($200–$250, first attempt within 24–48 business hours) when the FRCP 4(m) window is narrowing or the answer period has begun running. Same-Day ($250–$300) for statute of limitations scenarios, TRO hearings, and any matter where same-day delivery confirmation is operationally required. Stake-Out ($325–$425) for corporate officer service requiring extended wait or for evasion scenarios generating GPS-verified records for an alternative service motion. The governing principle: speed without accuracy is counterproductive. A defective service attempt that is rejected or challenged does not extend the service deadline — it restarts the clock while the deadline continues to run. For the full speed-tier analysis and deadline framework, see our Legal & Fast corporate process service guide.

GPS-Verified Affidavits and the Documentation Standard

The affidavit of service is the document that proves service occurred, and in corporate litigation it must prove more than just “papers were delivered.” It must establish that the delivery was made on the correct entity, through an authorized service method, at the correct registered office address, on a date and at a time that can be confirmed against the applicable deadline. A corporate service affidavit that omits the agent’s designation, misidentifies the recipient’s role, or fails to specify the documents served is a defective affidavit that invites a FRCP 12(b)(5) motion.

Every Undisputed Legal corporate service affidavit documents six elements: (1) the entity’s exact registered legal name and the registered agent designation under which service was made; (2) the name and stated role of the person who accepted the papers — for commercial agent offices, the intake representative’s identifying information; (3) the specific documents served — summons, complaint, and any attached exhibits, identified by title; (4) the exact date and time of delivery; (5) GPS coordinates confirming the delivery location matches the registered office address on file with the Secretary of State; and (6) the process server’s name and credentials, including DCWP license number for any service in New York City’s five boroughs.

The GPS coordinate documentation is not a formality — it is the evidentiary foundation for defeating a factual challenge to the service location. When a defendant’s registered agent address is disputed, or when the defendant claims service was made at the wrong building or wrong office, GPS coordinates pinpointing the delivery location to within a few meters of the registered office address resolve that factual dispute before it becomes a contested hearing. For commercial agent deliveries at CT Corporation, CSC, or NRAI offices, the written intake receipt issued by the commercial agent’s staff is obtained at the time of delivery and referenced in the affidavit as corroborating evidence of the delivery, the agent’s authority, and the time of service.

For time-sensitive matters — statute of limitations scenarios, TRO applications, FRCP 4(m) deadline situations — the completed affidavit is electronically delivered to counsel the same day service is completed. Counsel has the documentation needed for any court filing or hearing on the same day the service occurs, without waiting for a paper affidavit to be signed, notarized, and mailed.

Why Undisputed Legal for Corporate Process Service

Undisputed Legal has served business entities in all 50 states across the full spectrum of corporate service scenarios — routine registered agent delivery, same-day TRO service, multi-entity coordination for complex commercial litigation, and international service through the Hague Convention in 120+ countries. The operational infrastructure that supports corporate service at this scale is built on five capabilities.

Nationwide server network. Process servers in all 50 states with pre-established access to commercial registered agent offices — CT Corporation System, Corporation Service Company, and NRAI — in every major city. Same-day service in multiple states requires servers who are physically positioned at the right location at the right time, with pre-confirmed office access. Multi-state parallel dispatch is a routine capability, not an emergency accommodation.

Live SoS database verification. Entity status, registered agent identity, and registered office address are confirmed from the live Secretary of State database at the time of every dispatch. Not from prior affidavits, not from the attorney’s file, not from cached search results. This verification step is what prevents stale-address failures and dissolved-entity misroutes before they occur.

Entity identification pre-check. Every corporate service engagement begins with a document review confirming that the entity name on the papers matches the SoS registration, that the entity type is correct, and that the proposed service method is authorized for that entity type. Discrepancies identified before dispatch are corrected before the server leaves; discrepancies identified after delivery require re-service.

FRCP 4(m) deadline awareness. Every corporate engagement is managed with awareness of the service deadline. Rush and same-day tiers are not just speed options — they are deadline management tools. When a service order arrives with the FRCP 4(m) deadline or the CPLR 306-b window close at hand, the dispatch timeline reflects that constraint from the moment the order is received.

GPS-verified affidavit infrastructure. Same-day electronic affidavit delivery for time-sensitive matters, GPS coordinates confirming the delivery location, and commercial agent intake receipts as corroborating documentation — all standard for every corporate service engagement, not available on request.

Frequently Asked Questions — Corporate Process Service

What is the difference between corporate process service and individual process service?

Individual process service involves locating and personally delivering legal papers to a natural person. Corporate process service involves delivering papers to a business entity — which cannot personally receive documents — through the legally authorized recipients designated for that entity type: typically the registered agent, or an officer or managing agent. Corporate service is governed by FRCP 4(h) in federal court and the applicable state corporate statute. The registered agent infrastructure — commercial agents with staffed offices in every state — makes corporate service predictable and verifiable in a way that individual service of an evasive person is not, but it introduces its own complexity around entity identification, agent verification, and documentation standards.

Do I serve the corporation's attorney, or its registered agent?

The registered agent is the correct service recipient for commencing an action against a corporation. Serving the corporation's attorney commences nothing; an attorney does not automatically have authority to accept service on behalf of a client entity unless they have been specifically designated as an agent for service of process, which is uncommon. Service on the registered agent is the standard, reliable method for initiating litigation. After the action is commenced and the defendant has appeared through counsel, subsequent papers are typically served on counsel under the applicable court rules — but that is a separate question from how to commence the action with valid service.

What happens if the registered agent refuses to accept service?

A registered agent may not legally refuse service that is properly made. If an individual purporting to be the registered agent refuses to accept papers, the process server should document the refusal — date, time, identity of the person, words used — and the refusal itself may constitute a completed service under some state statutes (the "tender rule": presenting papers to a person authorized to receive them constitutes service even if they physically refuse to take the documents). For commercial agents operating intake desks, refusal is rare; the commercial agent's intake staff accept papers on behalf of the entities they represent as a routine matter. If access to the registered office is blocked — office closed, building inaccessible — the server should document the attempt and the basis for non-completion, and the engagement will return for re-attempt or pivot to SoS fallback service.

Can I serve large corporations — Amazon, Google, JPMorgan Chase — through their registered agent?

Yes, registered agent service is the standard method for serving major corporate defendants. Amazon.com, Inc. and its subsidiaries (Amazon.com Services LLC, Amazon Web Services, Inc.) each maintain registered agents — typically Corporation Service Company — in their states of formation and in all states where they are qualified to do business. Google LLC and Alphabet Inc. similarly maintain CSC or CT Corporation as registered agents in Delaware and other states. JPMorgan Chase & Co., JPMorgan Chase Bank, N.A., and J.P. Morgan Securities LLC each have separate registered agents and must be served as separate entities if each is a named defendant. The entity identification step — confirming which specific Amazon, Google, or JPMorgan entity is the correct defendant — is the critical preliminary step before any service attempt on a large corporate family. For the complete treatment of multi-entity service in complex corporate litigation, see our advanced corporate process service guide.

What is FRCP 4(h) and how does it govern corporate service in federal court?

Rule 4(h) of the Federal Rules of Civil Procedure governs service on corporations and associations in federal court. Under FRCP 4(h)(1)(A), a domestic or foreign corporation may be served in the manner prescribed by state law in the state where the district court is located or where service is made. Under FRCP 4(h)(1)(B) — the most commonly used method — service may be made by delivering a copy of the summons and complaint to an officer, managing or general agent, or any other agent authorized by appointment or by law to receive service of process. The registered agent is the paradigmatic authorized-by-law agent under FRCP 4(h)(1)(B). Service under FRCP 4(h) must be completed within the FRCP 4(m) 90-day deadline unless the plaintiff shows good cause, such as ongoing settlement discussions — which courts typically do not find sufficient absent extraordinary circumstances.

If a corporation is incorporated in Delaware but headquartered in New York, where do I serve it?

Both the Delaware registered agent and the New York registered agent (or the New York Secretary of State, which is the universal statutory agent for all entities qualified in New York) are typically valid. Service through either produces valid service on the entity for purposes of the action. The practical question is which route is more reliable on the specific facts: if the entity's Delaware registered agent address is confirmed current, Delaware service is often faster to arrange. If the entity's New York agent address is confirmed and the action is in a New York court, the New York route may be more convenient for filing proof of service. For a foreign corporation that is qualified in New York, service on the New York SoS is always available as a fallback regardless of whether a private agent is designated. Consult with counsel on the preferred route given the specific forum, the entity's registration status in each state, and any deadline considerations.

What is the FRCP 4(m) 90-day deadline and how does it apply to corporate defendants?

FRCP 4(m) requires that service of process be completed within 90 days after the complaint is filed. The 90-day period runs from the filing date, not from the issuance of the summons, and it is not automatically extended by amended complaints, settlement discussions, or the defendant's failure to respond to informal outreach. If service is not completed within 90 days without good cause shown, the court must dismiss the action without prejudice — which, if the statute of limitations has since run, is effectively a dismissal with prejudice because re-filing would be time-barred. The 90-day clock applies to corporate defendants the same way it applies to individual defendants. FRCP 4(f) international service is the main exception: service under FRCP 4(f) in a Hague Convention country is exempt from the 4(m) deadline. For all domestic corporate defendants, the 90-day clock is always running.

How long does corporate process service take?

For routine service on a corporate registered agent — entity verified, registered agent confirmed, documents in order — first attempt is made within 3–7 business days. If same-day service is required and documents are received during normal business hours, same-day delivery is attempted that day, subject to commercial agent office hours and geographic dispatch logistics. Rush service (24–48 business hours) covers the range between routine and same-day. The answer period — how long the defendant has to respond after service — depends on the forum: 20 days under the CPLR in New York, 21 days under FRCP 12(a)(1)(A) in federal court (plus 3 days for mailing under FRCP 6(d) in some circumstances). The affidavit of service is electronically returned the same day service is completed for time-sensitive matters.
