Corporate Process Service: Registered Agent Requirements

Every corporation, LLC, and limited partnership formed or qualified to do business in any U.S. state is required by statute to maintain a registered agent and a registered office in that state. This is not a best practice or a corporate governance recommendation — it is a legal mandate enforced through administrative dissolution, SoS fallback service, and potential default judgment exposure. Understanding what the law actually requires of a registered agent, which entities are subject to those requirements, how requirements vary by state, and what happens when an entity fails to comply is foundational knowledge for every process server, litigation attorney, and compliance officer working with corporate defendants. This page sets out the statutory requirements in detail, organized first by entity type and then by jurisdiction, so practitioners can verify compliance before service and understand the fallback options when they find it missing. For the constitutional and procedural framework governing why registered agent service satisfies due process, see our registered agent legal framework guide. For the business-owner perspective on registered agent compliance, see our registered agents and process service guide. To place an order or discuss a service engagement, call (800) 774-6922.

Which Entities Are Required to Maintain a Registered Agent

State law imposes the registered agent requirement selectively based on entity type. Not every business operating in a state must maintain a registered agent — only entities that exist by virtue of a state filing. The practical consequence for process servers is that the first step in every corporate service engagement is entity-type identification, because entity type determines whether a registered agent exists at all, and if not, what the correct service method is.

Entities subject to the registered agent requirement in all 50 states: domestic corporations (for-profit and nonprofit), foreign corporations qualified to do business in the state, domestic LLCs, foreign LLCs registered to do business, domestic limited partnerships, foreign limited partnerships registered in the state, domestic limited liability partnerships, and foreign LLPs registered in the state. Professional corporations and professional LLCs are subject to the same requirement as their non-professional counterparts. In every case, the requirement attaches at the time of formation or foreign qualification and continues for as long as the entity remains in existence or qualified.

Entities not subject to the registered agent requirement: General partnerships formed under a state’s Uniform Partnership Act and sole proprietorships have no state formation filing and therefore have no registered agent requirement. A general partnership doing business under a trade name may have a fictitious business name filing or a DBA, but that is not a formation document and does not create a registered agent obligation. Sole proprietorships are the same: there is no formation filing, no registered agent, and no registered office. Service on a general partnership is governed by FRCP 4(h)(1)(B) — delivery to an officer, managing or general agent, or any other agent authorized by appointment or law to receive service — or by the state equivalent. Service on a sole proprietor is governed by FRCP 4(e) individual service rules, or CPLR 308 in New York. The absence of a registered agent does not make these entities harder to serve; it means the service method is different from the entity types that have one.

Attorney consultation is recommended when the entity type is uncertain or when the operating entity and the named defendant do not clearly correspond to a formation filing in any state. Misidentifying the entity type can produce a service attempt at a registered agent address for an entity that has no registered agent, which constitutes a defective service.

What Qualifies as a Registered Agent — Statutory Standards

Every state’s corporate statute defines who or what may serve as a registered agent. The definitions vary at the margins, but two core categories appear in every jurisdiction: the individual resident agent and the commercial registered agent. Understanding the distinction matters for process servers because it determines what documentation to expect at the point of delivery and what intake procedures the agent will follow.

Individual registered agent. An individual may serve as the registered agent of a corporation or LLC if the individual: (1) is a resident of the state in which they are serving as agent, meaning they have a physical domicile or place of business in that state; and (2) has a physical street address in that state that constitutes the registered office. An officer, director, or employee of the entity itself may serve as its registered agent in most states, provided they satisfy the residency and physical address requirements. This arrangement is common in closely held corporations and LLCs with single-state operations. The individual agent receives service papers in person at the registered office address and is personally responsible for forwarding them to the entity.

Commercial registered agent. A commercial registered agent is a business entity — not an individual — that is authorized to do business in the state and holds itself out as providing registered agent services for hire. Commercial agents must themselves maintain a physical registered office in the state and must be available during normal business hours to accept service on behalf of every entity they represent. The dominant commercial agents — CT Corporation System, Corporation Service Company (CSC), and National Registered Agents Inc. (NRAI) — maintain staffed offices in all 50 states and receive service on behalf of hundreds of thousands of corporate entities. Commercial agents operate under internal intake procedures: a person at the desk receives the papers, issues a written receipt, records the delivery time, and transmits the papers to the entity. That written receipt is referenced in the process server’s GPS-verified affidavit as corroborating documentation of the delivery.

The Model Registered Agents Act (MoRAA), discussed in detail below, created a formal third category: the listed commercial registered agent. Under MoRAA, a commercial agent that files a listing statement with the SoS is recognized as a listed commercial agent for all entities it represents in that state, without needing to appear on each entity’s individual formation filing. In states that have not adopted MoRAA — New York, California, Delaware, Florida, and Texas among them — the commercial agent’s identity is verified entity by entity through the SoS database.

The Registered Office Requirement — Physical Presence Rules

A registered agent designation is only valid if paired with a registered office that satisfies the physical presence requirements of the state. The registered office requirement is distinct from the agent qualification requirement: an entity can have a qualified agent but an invalid registered office, producing a defective agent designation that cannot receive valid service.

Street address, not a PO box. Every U.S. state requires that the registered office be identified by a physical street address. A post office box does not satisfy the registered office requirement in any state. A mailbox at a UPS Store or similar mail-forwarding service does not satisfy the requirement, even if the address format resembles a street address. The distinction is physical presence and in-person accessibility: the registered office must be a location where a process server can physically appear and personally deliver documents to a person authorized to accept them.

Open during normal business hours. The registered office must be accessible during normal business hours on normal business days. This requirement exists because service of process must be capable of completion by personal delivery. A registered office that is only accessible by appointment, is unstaffed, or is located in a building that requires security clearance to enter creates a functional access barrier that state statutes were not designed to accommodate. Commercial registered agent offices address this requirement by maintaining fixed business hours with intake staff at every office location. This is the operational reason why process servers maintain current address records for CT Corporation, CSC, and NRAI offices in every major city — the physical accessibility of these offices is the foundation of reliable corporate service.

Virtual office disqualification. The rise of virtual office services — shared desk addresses that provide a mailing address and telephone answering but no permanent physical staffing — has created a compliance gap that state statutes are increasingly addressing. A virtual office address used as a registered office fails the physical presence and accessibility tests in most states. It cannot receive in-person service because there is no agent present to accept delivery. Some states have enacted specific provisions barring registered offices at known virtual office addresses. Process servers encountering a registered office address that appears to be a shared workspace or mailbox service should verify current entity status through the live SoS database before dispatching, and route to SoS fallback service if the address is undeliverable.

Change of registered office. When an entity changes its registered agent or registered office, the change is effective only upon the SoS accepting the filed amendment. The new address does not become the operative registered office when the filing is mailed or submitted — it becomes effective when the SoS records the change. Process servers always verify the current registered office address from the live SoS database at the time of dispatch, not from prior affidavits, attorney files, or cached search results, because the operative address is whatever the SoS database reflects at the moment of service.

State-Specific Requirements: Delaware

Delaware is the incorporation jurisdiction of choice for the majority of U.S. public companies and a large share of closely held corporations, making its registered agent requirements among the most practically significant in the country. The governing statute is 8 Del. C. § 132, which requires every corporation incorporated in Delaware to maintain a registered agent with a registered office — a physical street address — in the State of Delaware. The registered agent requirement persists regardless of where the corporation actually operates; a Delaware corporation that conducts all of its business in Texas still must maintain a Delaware registered agent.

Delaware does not require the registered agent to be a Delaware resident if the agent is a business entity — it requires only that the agent maintain a physical registered office address in Delaware. This has made Delaware a natural home for the large commercial registered agent industry. CT Corporation System and The Corporation Trust Company (its predecessor affiliate) maintain offices at 1209 Orange Street, Wilmington, Delaware 19801 — one of the most heavily served commercial addresses in American corporate law. Corporation Service Company maintains its Delaware office at 251 Little Falls Drive, Wilmington, Delaware 19808. The annual Delaware franchise tax report, due March 1 for domestic corporations, is the mechanism by which Delaware entities confirm or update their registered agent. An entity that fails to file and pay loses good standing; extended failure results in void status and administrative dissolution under 8 Del. C. § 510.

Service on a Delaware corporation through its Delaware registered agent constitutes valid service under 8 Del. C. § 321 regardless of where the corporation’s principal place of business is located. For entities incorporated in Delaware but sued in another state, an attorney must decide whether to serve the Delaware registered agent (valid service under Delaware law, which the court in the other state will recognize) or the foreign-qualification registered agent in the state where the action is filed. Both methods are typically valid; the Delaware route is frequently used when the other state’s agent address is stale or unconfirmed. For guidance on Delaware Secretary of State fallback service, see our Delaware SoS service guide.

State-Specific Requirements: New York

New York operates a registered agent system that is structurally different from most other states. Under NY BCL § 305 and NY LLCL § 301, the New York Secretary of State — acting through the Department of State — is designated by statute as the registered agent of record for every domestic corporation, foreign corporation authorized to do business in New York, domestic LLC, and foreign LLC registered in New York. This is a universal statutory designation: no entity needs to appoint the SoS; the SoS is the agent by operation of law.

Entities may additionally designate a private address for service forwarding by the DOS. Under this system, the DOS receives service papers, collects its statutory fee, and forwards the papers to whatever address the entity has designated in its DOS filings. That designated address is the place to which the DOS mails the forwarded papers — it is not an alternative registered office for direct in-person service. The practical consequence is that service on a New York entity can proceed through two routes: (1) direct service on the New York Secretary of State at One Commerce Plaza, 99 Washington Avenue, Albany, New York 12231, with the required fee; or (2) direct service on a private registered agent — such as CT Corporation System at 28 Liberty Street, New York, New York 10005 — if the entity has designated one and the attorney prefers direct commercial agent service.

The New York biennial DOS statement (required every two years under BCL § 408) is the mechanism for updating the forwarding address on file with the DOS. An entity that fails to file its biennial statement loses the ability to keep its forwarding address current, but service on the DOS itself remains valid because the DOS is the statutory agent — the forwarding problem is the entity’s problem, not the plaintiff’s. For corporations registered in New York City’s five boroughs, process servers carrying DCWP licenses document their license number on the GPS-verified affidavit of service as evidence of regulatory compliance with New York City’s licensing requirements.

State-Specific Requirements: California and Washington

California. California requires every corporation, LLC, and limited partnership formed or qualified in the state to designate an agent for service of process. The governing statute for corporations is Cal. Corp. Code § 1502 (domestic) and Cal. Corp. Code § 2105 (foreign); for LLCs, Cal. Corp. Code § 17701.09. An individual agent must be a California resident with a California street address. A commercial agent must be a “registered corporate agent” listed with the California Secretary of State — not every business entity qualifies, only those that have filed with the SoS for that purpose. Corporation Service Company maintains its California registered office at 2710 Gateway Oaks Drive, Suite 150N, Sacramento, California 95833. CT Corporation System maintains its California office at 330 North Brand Boulevard, Suite 700, Glendale, California 91203.

California’s Statement of Information — filed annually by corporations and biennially by LLCs — is the mechanism for updating registered agent information. An entity that fails to file on time loses good standing with the California Franchise Tax Board and may be suspended; a suspended California entity cannot defend itself in litigation. Service on a suspended California entity through its registered agent is still valid service; the suspension affects the entity’s litigation rights, not the plaintiff’s service rights. The California SoS maintains a live online database for agent address verification.

Washington. Washington requires every business entity formed or registered in the state to maintain a registered agent under RCW 23B.05.010 (corporations) and RCW 25.15.011 (LLCs). Washington issues a Unified Business Identifier (UBI) number to every registered entity; the UBI is the primary lookup key in the Washington SoS database. Corporation Service Company maintains a Washington registered office at 300 Deschutes Way SW, Suite 208, Tumwater, Washington 98501. Washington entities that fail to maintain a registered agent or file required annual reports become subject to administrative dissolution under RCW 23B.14.200. For entities that have lost their registered agent in Washington, the Washington Secretary of State provides a statutory fallback service route under RCW 23B.05.040.

Consequences of Failing to Maintain a Registered Agent

Failure to maintain a registered agent in compliance with state requirements triggers a cascade of statutory consequences that affect both the entity’s corporate standing and the plaintiff’s service options. Understanding these consequences is essential for process servers who encounter inactive, dissolved, or delinquent entities.

Administrative dissolution. Every state authorizes the Secretary of State to administratively dissolve an entity that fails to maintain a registered agent or fails to file required annual reports confirming registered agent status. The dissolution process typically involves a notice period — the SoS notifies the entity’s last known registered agent and, in some states, mails notice to the principal office address on file. If the deficiency is not cured, dissolution becomes effective. Administrative dissolution strips the entity of its right to affirmatively use the courts in some states — it cannot bring a new action or maintain an existing action — but it does not extinguish the entity as a target of litigation.

SoS fallback service for dissolved entities. A dissolved entity is still suable, and every major state provides a statutory mechanism for serving it. In New York, NY BCL § 306 and § 307 authorize service on the SoS as agent for a dissolved domestic or foreign corporation; the SoS forwards to the last known address on file. In Delaware, 8 Del. C. § 132 authorizes the SoS to act as agent for service on any Delaware corporation that has failed to maintain a registered agent. In New Jersey, N.J.S.A. 14A:4-5 provides the equivalent mechanism. In California, Cal. Corp. Code § 416.10(b) authorizes service on the California SoS for a dissolved foreign corporation. Process servers and counsel confirm entity status before dispatch; if the entity is dissolved, the SoS fallback route is typically the correct initial approach rather than attempting service at a commercial agent address that may no longer be accepting service on behalf of the entity.

Commercial agent resignation. A commercial registered agent may resign from representing a specific entity by filing a resignation notice with the SoS. After the resignation becomes effective, the entity has no registered agent on file, and the SoS typically assumes fallback agent status by statute during a cure period. If the entity does not appoint a new agent within the cure period, administrative dissolution follows. For process servers, a resignation on the SoS database means the commercial agent’s address is no longer a valid service address for that entity, and the SoS route must be used instead.

When an entity’s registered agent status is unclear — resigned, dissolved, or showing a stale address — consult with counsel before proceeding to ensure the chosen service method satisfies the applicable statute and that the timing of service is defensible.

Annual Report Obligations and Registered Agent Maintenance

Annual reports and periodic information statements are the statutory mechanism by which states verify that every registered entity continues to maintain a valid registered agent. The filing requirement creates a regular checkpoint — typically once per year or every two years — at which the entity must confirm or update its registered agent and registered office address. For process servers, the practical lesson is that the period between filings is the window during which registered agent information can go stale. Addresses, agents, and agent offices all change between report filings, and those changes may not be reflected in the SoS database until the next periodic filing updates the record.

Delaware requires domestic corporations to file an annual report and pay franchise tax by March 1 of each year. The annual report includes a confirmation of the registered agent and registered office address. Delaware LLCs file an annual tax report by June 1. New York requires a biennial DOS statement for both corporations and LLCs, filed every two years; the statement must include the name and address of the registered agent and the address to which the DOS will forward service papers. California requires corporations to file a Statement of Information annually, and LLCs to file biennially; both statements include the agent’s name and address. Washington requires an annual report for all entity types, due on the last day of the entity’s anniversary month; the report must include current registered agent information.

The staleness problem is most acute in states with biennial filing cycles. A New York LLC’s registered agent address on the SoS database may be up to two years old. A commercial agent that has relocated its New York office during that period — CT Corporation moved within Manhattan in 2013; CSC has similarly relocated offices in various states over the years — may not have a current address on file for that specific entity even though its general commercial agent listing is current. Process servers always verify against the live SoS database at the time of dispatch, cross-referencing the entity-specific agent address with current knowledge of the commercial agent’s operating office locations.

The Model Registered Agents Act — Standardization and State Adoption

The National Conference of Commissioners on Uniform State Laws (NCCUSL) promulgated the Model Registered Agents Act in 2006 and revised it in 2011. MoRAA’s core purpose was to address the fragmented, state-by-state approach to registered agent requirements by creating a uniform framework that commercial agents operating nationally could comply with through a single set of standards. Before MoRAA, a national commercial registered agent had to navigate 50 different qualification frameworks, filing requirements, and liability rules. MoRAA created a portable commercial agent standard applicable across all adopting states.

The MoRAA two-tier system. MoRAA distinguishes between two categories of registered agent. A listed commercial registered agent is an entity that files a single listing statement with the SoS of each adopting state, identifying itself as a commercial agent and providing its registered office address for that state. Once listed, the commercial agent may represent any number of entities in that state without each entity separately identifying the agent in its own formation documents — the entity simply states in its formation filing that it is represented by a listed commercial registered agent by name. A noncommercial registered agent is any individual or entity — including an officer of the represented entity — that serves as registered agent for one or a small number of entities and does not file a listing statement. Noncommercial agents must appear in each entity’s formation documents.

States that have substantially adopted MoRAA include Utah, Montana, Nevada, Alabama, Idaho, North Dakota, Arkansas, and Arizona, among others. In these states, CT Corporation, CSC, and NRAI operate as listed commercial agents; their current registered office address and listing status can be confirmed at the state-agent level rather than requiring entity-by-entity lookup. States that have not adopted MoRAA include New York, California, Delaware, Florida, and Texas — the five most commercially significant states for corporate litigation. In these states, the registered agent is confirmed per entity through the individual entity’s SoS filing. There is no shortcut: process servers and attorneys verify the agent for each named defendant entity separately.

For complex multi-entity corporate service involving defendants in multiple states, MoRAA adoption status affects verification workflow: MoRAA states permit faster commercial agent confirmation, while non-MoRAA states require full entity-by-entity SoS database queries for each defendant.

Process Server Verification Protocol — Four Steps Before Dispatch

The registered agent requirements described in the preceding sections translate directly into a pre-dispatch verification protocol that Undisputed Legal runs on every corporate service engagement. The protocol exists because failures at the registered agent level — stale addresses, dissolved entities, resigned agents, commercial agent office relocations — are among the most common causes of defective corporate service, and they are all preventable through proper verification. The four steps are sequential: each step’s output informs the next.

Step 1 — Entity status. Query the SoS database in the state of incorporation (or formation) and, if different, the state of foreign qualification where service is to be made. Confirm the entity is active and in good standing. If the entity is suspended, dissolved, or revoked, note the status and route to SoS fallback service rather than the registered agent address. An inactive entity’s registered agent may no longer accept service on its behalf, making a dispatch to the commercial agent address both potentially ineffective and certainly inefficient.

Step 2 — Registered agent identity. Confirm the current registered agent from the live SoS database. Do not rely on the attorney’s complaint caption, a prior affidavit of service, or a search result cached from a previous matter. Commercial agents change on contract renewals; individuals resign; entities switch from individual to commercial agents as they grow. The registered agent on file at the moment of service is the only registered agent that matters.

Step 3 — Registered office address. Confirm the current registered office address for the specific entity from the live SoS database. For commercial agents, cross-reference the entity-specific address against current knowledge of the commercial agent’s operating office locations. If the SoS database shows an address that no longer corresponds to an active commercial agent office — because the agent relocated and the entity has not yet filed an updated address — the address is stale and delivery there will not result in valid service on the agent.

Step 4 — Office hours and accessibility. Confirm the commercial agent office’s current business hours and any access requirements before dispatch. Major commercial agent offices maintain consistent hours — typically 8:00 AM to 5:00 PM Monday through Friday, excluding holidays — but those hours are operational constraints on same-day service. A server dispatched at 4:30 PM to an office that closes at 5:00 PM has a narrow window; a server dispatched at 5:15 PM to a closed office has no service that day. For NYC five-borough deliveries, process servers carry DCWP license credentials and document the license number on the GPS-verified affidavit of service.

The GPS-verified affidavit documents: the entity’s exact registered legal name and the agent under which service was made; the name and role of the individual who accepted the papers; the specific documents served; the exact date and time of delivery; GPS coordinates confirming the delivery location matches the registered office address on file; and the process server’s credentials. For commercial agent deliveries, the written receipt issued by the commercial agent’s intake staff is obtained and referenced in the affidavit as corroborating documentation.

When Registered Agent Service Fails — Fallback Hierarchy

Despite proper verification, registered agent service sometimes cannot be completed: the agent has resigned and no successor is on file, the entity is dissolved, the registered office address is undeliverable, or the commercial agent’s office is inaccessible. The fallback hierarchy provides a structured approach to completing service when the primary route is unavailable.

Tier 1 — Registered agent at verified registered office. The default route for all corporate service: personal delivery to the registered agent or an authorized representative at the registered office address confirmed through the live SoS database. Generates a GPS-verified affidavit and commercial agent receipt (for commercial agent deliveries).

Tier 2 — Secretary of State fallback service. Available when the registered agent has resigned, the entity is dissolved or void, or the registered office address is undeliverable. The SoS route is authorized by statute in every state: NY BCL § 306/307 (New York), 8 Del. C. § 132 (Delaware), N.J.S.A. 14A:4-5 (New Jersey), Cal. Corp. Code § 416.10(b) (California), RCW 23B.05.040 (Washington). The SoS charges a statutory fee and forwards service papers to the entity’s last known address on file. For guidance on the New York Secretary of State service procedure, see our NY SoS service guide.

Tier 3 — Court-ordered alternative service. When both Tier 1 and Tier 2 are unavailable or insufficient, counsel may move for court-ordered alternative service under FRCP 4(h)(1)(A) or the applicable state equivalent. The motion requires a due-diligence showing: documented attempts at registered agent service, documented attempts at SoS service if attempted, and evidence that the entity has evaded service. GPS-verified records of all service attempts and affidavits of due diligence support the motion.

The timing consequences of SoS fallback service vary by state and statute. In some states, service on the SoS is deemed effective on the date of SoS receipt; in others, effective service requires a further event such as SoS forwarding or the expiration of a notice period. Consult with counsel before relying on SoS service to satisfy a deadline-sensitive FRCP 4(m) window, statute of limitations, or scheduled court event.

Frequently Asked Questions — Registered Agent Requirements

Does every business entity have to maintain a registered agent?

No. The registered agent requirement applies only to entities that exist by virtue of a state formation filing: corporations (domestic and foreign), LLCs, limited partnerships, limited liability partnerships, and similar statutory entities. General partnerships and sole proprietorships have no formation filing and therefore no registered agent requirement. A process server approaching a sole proprietorship or general partnership uses individual service rules (FRCP 4(e) / CPLR 308) or officer/managing agent rules (FRCP 4(h)(1)(B)) rather than looking for a registered agent.

Can a PO box serve as a registered office?

No state permits a post office box to serve as a registered office. The requirement in every jurisdiction is a physical street address at which a process server can appear in person and deliver documents to an agent who is present and authorized to accept service. A PO box, a mailbox at a UPS Store, and a virtual office address without permanent staffing all fail this requirement. An entity using any of these as its registered office address is technically non-compliant, and service attempted at such an address may not constitute valid service on the registered agent.

What happens to service of process if a company is administratively dissolved?

An administratively dissolved entity is still suable. Every major state provides a statutory fallback: the Secretary of State becomes the agent for service on the dissolved entity (NY BCL § 306/307, 8 Del. C. § 132, N.J.S.A. 14A:4-5, Cal. Corp. Code § 416.10(b)). The SoS service procedure requires the applicable statutory fee and the SoS forwards service papers to the entity's last known address on file. Process servers confirm entity status before dispatch; if the entity is dissolved, the SoS fallback is the correct route. For complex fact patterns — dissolved entity that has been reinstated, or dissolution that occurred between the filing of the complaint and the service attempt — consult counsel before proceeding.

Can an officer of the corporation serve as its registered agent?

Yes, in most states. An officer, director, or employee of the entity may serve as the registered agent if they: (1) are a resident of the state in which they are serving as agent; and (2) have a qualifying physical street address in that state that can serve as the registered office. This arrangement is common in closely held corporations and single-state LLCs. It creates a practical vulnerability: if the officer resigns, relocates, or dies, the entity must promptly file a new registered agent designation or it will have no valid agent on file. Commercial registered agents eliminate this single-point-of-failure risk.

If an entity is incorporated in Delaware but sued in New York, which registered agent do I serve?

Both options may be valid, and counsel makes the strategic choice. A Delaware corporation that is also qualified as a foreign corporation in New York has two registered agents: its Delaware agent (for Delaware-jurisdiction service under 8 Del. C. § 321) and its New York registered agent or the NY Secretary of State (for New York-jurisdiction service under NY BCL § 307). Service through either is typically effective to commence the action; the question is which method is faster, which address is more reliably current, and whether the applicable court rules specify a preference. For a defendant with a stale or uncertain New York agent address, serving the Delaware registered agent may be the more reliable option. Consult with counsel to determine which route satisfies the applicable procedural rules for the forum in which the action is filed.

What is the difference between a listed commercial registered agent and a noncommercial registered agent under MoRAA?

Under the Model Registered Agents Act, a listed commercial registered agent files a single listing statement with the SoS of each adopting state and is then recognized as a commercial agent for all entities that designate it — without each entity separately identifying the agent's address in its formation documents. CT Corporation, CSC, and NRAI are the primary listed commercial agents. A noncommercial registered agent — an individual or entity that serves as agent for one or a small number of entities — must appear by name in each entity's own formation or qualification filing. The practical difference for process servers: in MoRAA-adopting states, confirming a listed commercial agent's current office address can be done at the agent level; in non-MORAА states (NY, CA, DE, FL, TX), every entity's SoS filing must be checked individually.

If the SoS database shows a stale registered agent address, what is the correct procedure?

Do not dispatch to an address you have independent reason to believe is no longer the commercial agent's operating office. Cross-reference the entity-specific SoS address against current knowledge of the commercial agent's active office locations. If the address is stale — for example, the SoS database still shows CT Corporation at an address the agent vacated two years ago — the entity has not filed an updated registered office address, and delivering papers to the old address is unlikely to result in valid service on the current agent. Route to SoS fallback service and note in the affidavit the basis for the determination that the registered agent address on file is not the current operating address. Document all verification steps in the file for use in any subsequent due-diligence motion.

Does the affidavit of service need to document the registered agent's qualifications?

The affidavit must document sufficient facts to establish that service was made on the entity's registered agent at the registered office — specifically: the entity's exact registered legal name, the registered agent designation under which service was made, the name and role of the individual who accepted the papers, the exact date and time of delivery, and the address where delivery occurred. For commercial agent deliveries, referencing the written receipt issued by the agent's intake staff corroborates the agent's authority. GPS-verified affidavits additionally document the GPS coordinates of the delivery location, confirming the delivery address matches the registered office on file. Whether the affidavit must affirmatively state that the agent was "qualified" under state law is a form requirement that varies by jurisdiction; consult counsel regarding the specific form requirements of the court in which the affidavit will be filed.
