How to Serve Business Entities – Corporate Process Service

Entity Type Determines Service Method: The Foundational Rule

The most consequential variable in business entity service of process is the entity’s legal form. A domestic corporation, a foreign corporation, a limited liability company, a limited partnership, a general partnership, and a sole proprietorship are each governed by different service rules — different statutes, different authorized recipients, and different fallback procedures when the primary method fails. Confusing entity type means applying the wrong service rule, which means delivering to the wrong person or address, which produces a motion to dismiss for insufficient service. This page is the practitioner’s reference for serving every type of business entity correctly under both federal and key state rules. Call (800) 774-6922 to confirm the correct service method for a specific entity before dispatching.

The registered agent is the default service target for most organized business entities — corporations and LLCs in particular — because the designation represents the entity’s voluntary, publicly recorded submission to service at a specific address. But the registered agent is not always available, not always current, and does not apply to every entity type. The sections below address each entity type in turn, with the applicable federal rule, key state-specific variations, and the correct fallback procedure when the primary method cannot be completed.

Serving Domestic Corporations

A domestic corporation — incorporated in the state where the lawsuit is pending — is the most commonly served business entity type and has the most clearly established service rules. In federal court, FRCP 4(h)(1)(B) authorizes service by delivering the summons and complaint to “an officer, a managing or general agent, or any other agent authorized by appointment or by law to receive service of process.” The registered agent is authorized by appointment — service on the registered agent is the cleanest, most defensible method. Consult a licensed attorney to confirm the applicable service rules for your specific matter before ordering.

New York — CPLR 311(a)(1). New York authorizes service on a domestic corporation by delivering the summons to “an officer, director, managing or general agent, or cashier or assistant cashier or to any other agent authorized by appointment or by law to receive service.” The registered agent designated under N.Y. Bus. Corp. Law § 304 is such an agent. The New York Secretary of State serves as statutory agent under BCL § 306 for domestic corporations that have designated the SoS as their registered agent, and as fallback agent for dissolved or unregistered entities.

Delaware — 8 Del. C. § 321. Every Delaware corporation must maintain a registered agent under § 321. Service on the registered agent — typically CT Corporation System or Corporation Trust Company at 1209 Orange Street, Wilmington — is the standard procedure. The Delaware Secretary of State serves as fallback agent under 8 Del. C. § 132 when the registered agent cannot be found or has resigned without a successor.

California — Cal. Corp. Code § 416.10. California authorizes service on a domestic corporation by delivering to the registered agent, to an officer (president, vice-president, secretary, CFO, or general manager), or — after reasonable diligence to locate any of the above — to the Secretary of State under Cal. Corp. Code § 1702. California’s reasonable diligence requirement before SoS fallback is more demanding than most states; documenting the failed attempts to locate the registered agent or an officer is necessary before proceeding to SoS service.

What “managing agent” requires. FRCP 4(h)(1)(B) and many state service rules permit service on a “managing or general agent.” This is not any employee — it requires a person with managerial authority over the corporation’s affairs in the forum jurisdiction, sufficient that notice served on them will reach the corporation’s decision-makers. A receptionist, an administrative assistant, or building security does not qualify. When the registered agent is unavailable, service on a named officer confirmed against the current SoS filing is the safer alternative to relying on the managing-agent characterization.

Serving Foreign Corporations (Out-of-State Entities)

In U.S. corporate law, a “foreign corporation” means a corporation incorporated in a state other than the state where service is being made — not a corporation incorporated in another country (which is an “alien corporation”). A Delaware corporation being sued in New York is a foreign corporation in New York. Service rules for foreign corporations depend on whether the entity has formally qualified to do business in the forum state.

Qualified foreign corporations. A foreign corporation that holds a certificate of authority to do business in the forum state must maintain a registered agent there as a condition of qualification. Service on that registered agent is legally complete on the entity. FRCP 4(h)(1)(B) applies identically to domestic and qualified foreign corporations. The only additional verification step is confirming that the foreign corporation’s qualification is current — an entity whose certificate of authority has been revoked no longer has an active registered agent in the state and may require SoS fallback service instead.

Unqualified foreign corporations — SoS fallback. A foreign corporation doing business in the forum state without a certificate of authority has no registered agent there. Most states provide a fallback. In New York, BCL § 307 permits service on the New York Secretary of State for foreign corporations doing business without authority — a formal filing at One Commerce Plaza, 99 Washington Avenue, Albany NY 12231 with the required fee and affidavit. In New Jersey, N.J.S.A. 14A:13-4 governs. The Delaware Secretary of State provides an analogous mechanism for entities with lapsed authority under Delaware law. Consult a licensed attorney before using SoS fallback for an unqualified foreign corporation to confirm the specific requirements and the factual predicate for “doing business” in the forum state.

The “doing business” threshold. Whether a foreign corporation is “doing business” in a state without qualification is fact-specific. A company with employees, physical operations, a warehouse, or retail locations in the state typically qualifies. A company that merely sells products nationally online with no physical presence typically does not. The SoS fallback is not available simply because the company has customers in the state. Counsel must assess the factual record before electing this mechanism.

Serving Limited Liability Companies (LLCs)

LLCs are a distinct entity type with service rules that parallel but are not identical to those for corporations. FRCP 4(h)(1)(B) covers LLCs as unincorporated associations — the rule authorizes service on an officer, a managing or general agent, or any agent authorized by appointment or by law. Most state LLC statutes designate the registered agent, a member, or a manager as authorized to accept service. Consult a licensed attorney to confirm the applicable LLC service rules in the relevant state before ordering.

New York — N.Y. LLC Law § 303. New York authorizes service on a domestic LLC by delivering to the registered agent designated under LLCL § 301, a member, or a manager. The New York Secretary of State acts as registered agent for LLCs that have designated it in lieu of a private agent. For foreign LLCs doing business without authority in New York, LLCL § 303(b) provides a parallel SoS fallback procedure.

Delaware — 6 Del. C. § 18-104 and § 18-105. Delaware LLCs must maintain a registered agent under § 18-104. Service on the registered agent is the standard procedure. The Delaware Secretary of State serves as fallback under § 18-105 when the registered agent cannot be found, has resigned, or the entity’s certificate has been cancelled.

Member vs. manager: practical distinction. In a member-managed LLC, any member is typically authorized to accept service on behalf of the entity. In a manager-managed LLC, the managers hold authority over the entity’s affairs — serving a passive member of a manager-managed LLC creates a contested-service risk. The LLC’s organization documents and the state entity database may indicate the management structure. When the registered agent is unavailable, confirm the management structure before selecting an alternative recipient. Professional LLCs (PLLCs) follow the same service rules as general LLCs in most states.

Serving Limited Partnerships

A limited partnership (LP) consists of general partners — who manage the partnership and bear unlimited liability — and limited partners, who are passive investors. For service of process, the general partner is the LP’s authorized representative. FRCP 4(h)(1)(B) applies to LPs as to other business associations.

Registered agent for LPs. Many limited partnerships maintain a registered agent as a condition of formation, particularly in Delaware, which requires registered agent designation under 6 Del. C. § 17-104. In New York, Partnership Law § 121-109 authorizes service on the LP’s registered agent, a general partner, or the New York Secretary of State under certain conditions. The New Jersey Secretary of State provides parallel coverage for NJ-registered LPs under N.J.S.A. 42:2C-14. Where a registered agent is on file and current, service on the registered agent is the preferred approach.

Serving the LP through the general partner. When the LP has no registered agent — common for older LPs or those registered in states without a mandatory registered agent requirement — service is made on a general partner in their capacity as general partner of the LP. The affidavit must reflect service on the named individual as general partner of the named LP, not service on the individual personally. Do not serve a limited partner as a substitute — limited partners typically have no authority to accept service on behalf of the LP, and service on a limited partner does not bind the entity.

Serving General Partnerships

A general partnership is formed by agreement between two or more persons who will conduct business together. In most states, no state filing is required for formation, no registered agent is required, and the partnership agreement is a private document — not a matter of public record. FRCP 4(h)(1)(B) covers general partnerships as unincorporated associations. Service on any general partner binds the partnership; each partner is an agent of the partnership for all partnership business, including acceptance of service.

Identifying current general partners. The primary challenge with general partnership service is locating current partners when the partnership has no public filing and no registered agent. Registered limited liability partnerships (LLPs) — a variation with limited liability for partners — are required to file with the state in most jurisdictions and may have a registered agent on file. For ordinary general partnerships without LLP registration, identifying partners may require review of prior court filings, recorded property documents, state professional license databases, or investigative skip-trace work. The affidavit must identify the accepting partner by name and confirm their role as a general partner of the named partnership.

Serving Sole Proprietorships: Individual Service Rules Apply

A sole proprietorship is not a separate legal entity. It is an individual — the owner — conducting business under a trade name. A “doing business as” (DBA) or fictitious name filing registers the trade name for identification and notice purposes, but it does not create a corporation, an LLC, or any other separate legal person that can be served through a registered agent. For service of process, a sole proprietorship is the individual owner, and service must comply with individual service rules.

Federal and state individual service rules. FRCP 4(e) governs service on an individual: personal delivery (Rule 4(e)(2)(A)); leaving the papers at the individual’s usual place of abode with a person of suitable age and discretion (Rule 4(e)(2)(B)); delivery to an agent authorized by appointment or law (Rule 4(e)(2)(C)); or the method permitted by state law in the forum state or state of service (Rule 4(e)(1)). In New York, CPLR 308 governs individual service. The summons must name the individual — the DBA name alone is insufficient for a sole proprietorship defendant.

When a business looks like a corporation but isn’t. Many businesses present with corporate-sounding names — “Smith Industries,” “Johnson Group” — but are sole proprietorships with no state entity filing. Before assuming a corporate registered agent exists, query the relevant SoS database. If no entity appears under that name, the “business” is likely a DBA operating under an individual or an unregistered partnership. Serving a non-existent registered agent for a non-existent corporation produces an affidavit that documents delivery to no one with any authority to receive it. Entity-type verification before dispatch is not optional — it is the threshold step.

The Entity Identification Problem: Trade Names, DBAs, and Legal Names

The most preventable error in business entity service is naming the wrong entity in the summons before service is attempted. Service on an entity that does not match the defendant’s registered legal name creates a defect: the papers were delivered to a registered agent for Entity A, but the summons names Entity B. That defect is available to defense counsel on a motion to dismiss regardless of whether the defendant had actual notice of the lawsuit.

The trade name trap. Major corporations and large LLCs routinely operate under trade names that differ from their registered legal names. “Whole Foods” is not a registered entity — Amazon.com Services LLC operates Whole Foods Market locations. “Chase Bank” does not appear in entity databases as a registered entity — JPMorgan Chase Bank, National Association is the chartered bank. “Google” is a brand name — Google LLC is the registered Delaware entity. The advanced corporate service guide covers the entity identification problem in more depth; the rule is consistent: confirm the exact legal name from the SoS database before the summons is drafted, not after a defective service objection is filed.

Exact name matching. Once the correct legal entity is confirmed, the summons must match the state registry exactly. “Corp.” and “Corporation” are not interchangeable if the entity’s filed name uses one form. “LLC” and “L.L.C.” may be treated differently at a commercial registered agent’s intake desk. Punctuation and abbreviation discrepancies are cited in defective-service motions precisely because they are objectively verifiable and facially apparent from the documents. The correct approach: copy the entity name verbatim from the current SoS database record into the summons.

When the Registered Agent Is Unavailable: The Fallback Hierarchy

Registered agent service is unavailable in three scenarios: the agent has resigned without a successor; the entity is dissolved, revoked, or lapsed; or the agent cannot be located at the registered address. In each case, a fallback exists — but the applicable fallback depends on entity type and state. Consult a licensed attorney to confirm the correct fallback procedure for your specific entity type and jurisdiction before proceeding.

Tier 1: Other authorized recipients for the entity type. Before invoking SoS fallback, determine whether another authorized recipient is accessible. For corporations: an officer (president, secretary, treasurer, or vice-president) or a managing or general agent with confirmed authority. For LLCs: a member or manager, with attention to the member-managed vs. manager-managed distinction. For LPs: a general partner. Service on these individuals in their official capacity is legally complete on the entity. The authorized recipient must be positively identified — not assumed from context or proximity to the business address.

Tier 2: Secretary of State as fallback agent. For dissolved, revoked, or unregistered entities, most states designate the Secretary of State as fallback agent through a formal filing procedure. In New York, BCL § 306 and § 307 govern corporations; LLCL § 303 governs LLCs; Partnership Law § 121-109 governs LPs. In Delaware, 8 Del. C. § 132 covers corporations without a registered agent; 6 Del. C. §§ 18-105 and 17-104 cover LLCs and LPs. In New Jersey, N.J.S.A. 14A:4-5 governs corporations. Each SoS fallback procedure requires specific documents and fees; service is legally complete when the SoS receives the papers, with forwarding to the entity’s last address on file.

Tier 3: Court-ordered substituted service. When all standard and fallback methods have failed or the entity is actively evading service, most courts will authorize substituted service by motion — publication, service by email, service through a parent company, or another method satisfying constitutional due process. This requires documented prior attempts, a motion, and a court order. Undisputed Legal documents every service attempt in GPS-verified records to support a substituted service application when necessary.

What does NOT constitute service. A receptionist who accepts documents at a corporate address is not a registered agent and, absent specific confirmed authority, is not a managing or general agent. A building security guard is not a corporate officer. An unnamed “employee” at a business location with no identified authority does not bind the entity. For the full legal framework governing authorized recipients, see our guide to registered agents in civil procedure and the registered agent compliance guide.

Undisputed Legal’s Business Entity Service Process

Undisputed Legal’s business entity service process begins with entity-type identification and verification — not dispatch. The entity’s legal form determines the applicable service rule, and the applicable service rule determines who is an authorized recipient. Getting these steps right before the process server leaves the office prevents the failure modes that produce defective affidavits and contested service.

Entity identification and SoS verification. We confirm the entity’s legal form from the state database, verify the exact registered legal name, identify the current registered agent (name, address, and entity status), and flag any discrepancies between the attorney’s specified entity name and the database record before dispatch. For entities without a current registered agent, we identify the applicable fallback procedure and advise counsel before any delivery attempt.

Authorized recipient confirmation and delivery. For registered agent service, we confirm the commercial agent’s current office address and intake hours. For officer or member service when the registered agent is unavailable, we confirm the identity and role of the intended recipient against public records. GPS-verified delivery is documented with the exact time, date, and coordinates of service, the name and role of the accepting party, and the specific documents served. For commercial registered agents — CT Corporation, CSC, NRAI — we obtain the written receipt at the time of delivery as independent corroborating evidence.

DCWP licensing for New York City. For business entity service in New York City’s five boroughs — registered agents at CT Corporation’s Manhattan office at 28 Liberty Street, CSC locations, and corporate officers at headquarters addresses in Manhattan, Brooklyn, Queens, the Bronx, and Staten Island — our process servers hold active New York City Department of Consumer and Worker Protection (DCWP) licenses, maintaining GPS-verified records in compliance with NYC Administrative Code § 20-403. Call (800) 774-6922 to discuss entity verification, service method selection, or multi-state coordination before dispatch.

Why Attorneys and Litigants Choose Undisputed Legal for Business Entity Service

Business entity service fails most often at the threshold — wrong entity identified, wrong registered agent verified, wrong authorized recipient served. Undisputed Legal eliminates these failures by treating entity verification as the first step, not the last. We have handled service for corporations, LLCs, limited partnerships, and general partnerships in all 50 states and coordinated international service in 120+ countries for alien corporations and international subsidiaries.

Entity-type expertise across all business forms. From a sole proprietorship served at the owner's home address to a Delaware-incorporated multinational served through its registered agent in the forum state and its state of incorporation simultaneously — Undisputed Legal has handled every entity type at every complexity level. Our process servers know the difference between a managing agent and a receptionist, between a member of a member-managed LLC and a passive investor in a manager-managed LLC, and between a registered agent service and the SoS fallback that replaces it when the agent has resigned.

GPS-verified documentation for every delivery. Every business entity service — whether a registered agent delivery at CT Corporation, an officer service at a corporate campus, or an LLC member service at a business address — produces a GPS-verified affidavit with coordinates, timestamp, accepting party identification, and the specific documents served. For complex matters with multi-entity service requirements, see our advanced corporate service guide. For business owners who want to understand the registered agent system from the compliance side, see Registered Agents: What Businesses Must Know.

Frequently Asked Questions

Is a registered agent always required for serving a business entity?

No — and the answer depends entirely on entity type. Corporations and LLCs are required to maintain registered agents in every state where they are formed or qualified to do business, which makes the registered agent the standard service target for these entity types. Limited partnerships frequently maintain registered agents, but the general partner is an equally valid service recipient. General partnerships are typically not required to maintain registered agents; service is on a partner directly. Sole proprietorships have no registered agent at all — they are individuals, and individual service rules apply. The correct question before ordering any business entity service is not "where is the registered agent?" but "what type of entity is this, and who is an authorized recipient for this entity type?"

Can I serve an LLC by serving any one of its members?

It depends on how the LLC is managed. In a member-managed LLC, any member is typically authorized to accept service on behalf of the entity. In a manager-managed LLC, the managers hold authority over the entity's operations — serving a passive member who holds no management authority creates a challenged-service risk because the member may not have authority to bind the LLC through acceptance of process. The safest approach for LLC service is always the registered agent first. If the registered agent is unavailable, identify whether the LLC is member-managed or manager-managed (often reflected in the state entity database or the operating agreement) before selecting a member or manager as the service target. State rules also vary — New York LLCL § 303, Delaware 6 Del. C. § 18-104, and California Corp. Code § 17701.16 each have specific provisions on this question.

What's the difference between serving a corporation at its headquarters vs. at its registered agent's office?

They are different methods with different legal effects and different risk profiles. Service on a registered agent is clean: the agent is authorized by law, the delivery is documented with a receipt, service is complete upon delivery, and the affidavit can reference the agent's statutory authority. Service at corporate headquarters involves identifying a specific authorized recipient — an officer, director, or managing agent — who must be present and identified by name and role. An officer personally served at headquarters is valid service on the corporation under FRCP 4(h)(1)(B) and most state service rules. But if the person who accepts the papers is not an officer or authorized agent — just the receptionist who happened to be at the front desk — the service may be defective. The registered agent eliminates this ambiguity; service at headquarters introduces it. For major corporations with commercial registered agents like CT Corporation, there is rarely a reason to serve at headquarters rather than at the registered agent.

What happens if the entity I need to serve has no registered agent currently on file?

A missing registered agent triggers a fallback service mechanism that varies by entity type and state. For most states, the Secretary of State becomes the default agent for entities whose registered agent has resigned or whose agent cannot be found — the SoS fallback. The procedure involves delivering process to the SoS office with the required statutory fee; service is legally complete at that delivery; the SoS then forwards to the entity's last address of record. In New York, BCL § 306 and § 307 govern corporations; LLCL § 303 governs LLCs. In Delaware, 8 Del. C. § 132 governs corporations without an agent; 6 Del. C. § 18-105 and § 17-104 cover LLCs and LPs. In New Jersey, N.J.S.A. 14A:4-5 governs. Each SoS fallback is a formal filing, not a delivery — and the specific requirements (documentation, fee, affidavit of prior attempts) must be followed exactly. Consult a licensed attorney before initiating SoS fallback service.

Can I serve a foreign corporation that has no registered agent in my state?

Yes, in most states, through the SoS fallback mechanism for foreign corporations doing business without authority. In New York, BCL § 307 provides this mechanism; in California, Cal. Corp. Code § 1702; in New Jersey, N.J.S.A. 14A:13-4. The procedure requires a showing — or at least a representation — that the foreign corporation is doing business in the state without having obtained a certificate of authority. What qualifies as "doing business" is a fact-specific inquiry: physical operations, employees, or regular commercial activity in the state typically suffice; mere online accessibility typically does not. Service is completed by delivering process to the Secretary of State with the required fee; the SoS then forwards to the foreign corporation's principal office or registered agent in its home state. Consult a licensed attorney to confirm the factual predicate before electing this mechanism.

How is service on a sole proprietorship different from service on a corporation?

Fundamentally: a sole proprietorship is the individual, so service follows individual rules, not corporate rules. There is no registered agent to serve — because there is no separate legal entity. The summons must name the individual owner by their legal name (not just the trade name of the business), and service must comply with FRCP 4(e) for federal actions or the applicable state individual service statute. In New York, that is CPLR 308. The individual must be served personally, at their usual place of abode with a suitable person, or by another method authorized by the applicable rule. Delivering papers to the business address as if it were a registered agent office accomplishes nothing legally — there is no entity at that address and no registered agent authorized to accept process on behalf of anyone.

What qualifies someone as a "managing agent" for service of process purposes?

The "managing or general agent" designation in FRCP 4(h)(1)(B) and parallel state rules requires a person with substantial managerial authority over the corporation's affairs within the forum jurisdiction — someone in a position where it is reasonable to infer that notice served on them will reach the corporation's decision-makers. Courts have consistently held that this requires more than employment: a receptionist, a front-desk employee, a delivery coordinator, or a customer service representative does not qualify, even if they are present at a corporate address during business hours. General managers, regional directors, vice-presidents, and other named officers with authority over the entity's operations in the forum state typically qualify. When in doubt, serve the registered agent — the registered agent is authorized by law, eliminating the managing-agent characterization question entirely.

Does serving the parent corporation constitute service on its operating subsidiary?

No — not as a general rule. A parent corporation and its subsidiary are distinct legal persons with separate registrations, separate registered agents, and separate legal obligations. Serving the parent does not bind the subsidiary, and vice versa, unless the subsidiary has expressly designated the parent as its agent for service of process (unusual) or there is a factual basis for alter ego liability that a court might use to treat the two entities as one (a merits-level determination that cannot be assumed at the service stage). If both parent and subsidiary are named defendants, each must be served separately through their respective registered agents or other authorized recipients. This is one of the most common errors in multi-entity litigation, and it is addressed in more depth in our guide to complex corporate service strategies.

Undisputed Legal handles service on every business entity type — corporations, LLCs, limited partnerships, general partnerships, and sole proprietorships — in all 50 states and 120+ countries. Entity verification, authorized recipient confirmation, GPS-verified affidavits, and multi-state coordination are standard on every engagement.
