Serving Legal Papers at CT Corporation – Step-by-Step Guide

CT Corporation System is the registered agent for more than 750,000 entities across all fifty states. Serving papers at CT Corp correctly requires seven discrete steps — each with a specific failure mode that can void the service entirely. This guide covers each step in sequence: what to do, why it matters, and what goes wrong when it is skipped. For the comprehensive reference covering CT Corp’s intake protocols, building access procedures, and state-by-state legal framework in depth, see our complete CT Corporation service guide. To order service or verify the correct office for your matter, call (800) 774-6922.

Step 1 — Confirm the Entity Uses CT Corporation as Its Registered Agent

Before anything else — before preparing documents, before scheduling a delivery, before dispatching a server — confirm that CT Corporation is currently the registered agent for the specific entity you are serving, in the specific state where you intend to serve.

How to confirm. Query the official Secretary of State entity search database for the relevant state. The entity record will identify the current registered agent name and registered address. You are looking for either “CT Corporation System” or, in Delaware, “Corporation Trust Company” — both are Wolters Kluwer subsidiaries, but they appear as different legal names in different state databases. Any other name (CSC, NRAI, Incorporating Services, a law firm, an individual) means CT Corporation is not the current registered agent and service at a CT Corp office will be non-service.

Why this step cannot be skipped. Registered agents change. A company that used CT Corporation last year may have switched to CSC this month. A server who assumes CT Corp is the agent based on prior experience, prior filings, or a general knowledge that “big companies use CT Corp” and delivers without verifying will find — after the limitations period has run — that service was never made. Undisputed Legal runs a fresh entity search before every registered agent delivery. This is not optional; it is a prerequisite to dispatch. For the full registered agent verification framework, see our registered agent requirements guide.

Step 2 — Identify the Correct CT Corporation Office for the State

CT Corporation operates registered offices in each state, but not every state’s CT Corp office is where practitioners expect it to be. The correct office is the one listed as the registered agent’s address in that state’s entity database — not the nearest CT Corp office, not the CT Corp office nearest the courthouse, and not an office you have successfully served at in a prior matter involving a different entity.

The address verification rule. Use the address shown in the current state entity record. In California, some entities list 818 W. 7th Street in Los Angeles; others list 330 N. Brand Blvd in Glendale. In Delaware, “CT Corporation System” and “Corporation Trust Company” are two distinct entities operating at the same building (1209 Orange Street, Wilmington) but under different registered agent names — the documents must be directed to the correct name. In New Jersey, the registered office is in West Trenton, not downtown Trenton or Newark — a common misdirection. Always serve the address that appears in the current state database entry for the specific entity being served.

Multi-state engagements. When the same defendant entity is registered in multiple states and service is required in more than one state simultaneously, each state has its own CT Corporation address. A Delaware-incorporated entity with a New York registered office has a separate registered agent address in each state; service in each state goes to that state’s CT Corporation office. For multi-state service coordination, see our complex corporate process service solutions page. The Top 10 CT Corporation offices by state are listed below.

Step 3 — Prepare the Documents

Document preparation for CT Corporation service has three requirements that, if missed, produce defective service regardless of how cleanly the physical delivery is executed.

Exact entity legal name. The entity’s name on the summons and complaint must exactly match its registered legal name as it appears in the state’s entity database — including the correct corporate suffix (Inc., Corp., LLC, L.L.C., Ltd.). “ABC Corp” is not the same as “ABC Corporation” for service purposes if the registered name is the latter. The delivery address in the documents should read: [Entity Legal Name], c/o CT Corporation System [or Corporation Trust Company for DE], [full street address].

Complete document sets. CT Corporation requires that every page of the process being served be included — summons, complaint, all exhibits, any incorporated attachments. Presenting an incomplete set (complaint without exhibits, or summons without complaint) is grounds for rejection at the intake desk. If CT Corporation rejects the papers at intake, no service has been made and the server must return with a complete set.

Number of copies. CT Corporation typically requires at least two copies of the complete document set — one for its records and one to forward to the entity. Confirm the copy requirement for the specific state before arriving; some states or specific CT Corp locations have their own intake requirements regarding copy count or document format. Arriving with only one copy when two are required means the server leaves without service being completed.

Step 4 — Deliver During Business Hours

CT Corporation offices accept walk-in service of process delivery Monday through Friday during normal business hours — typically 8:30 a.m. to 5:00 p.m. local time, excluding federal and state holidays. Delivery outside these hours — arriving at 5:15 p.m., attempting service on a federal holiday, or delivering to building security at a closed office — does not constitute service on CT Corporation as registered agent.

High-rise locations requiring building security clearance. Several of CT Corporation’s highest-volume offices are in major commercial high-rises with lobby security and elevator access controls: 28 Liberty Street in New York (the former One Chase Manhattan Plaza), 818 W. 7th Street in Los Angeles, and 208 S. LaSalle Street in Chicago. At these locations, process servers must sign in at lobby security, identify the purpose as service of legal process, and wait for clearance before proceeding to the CT Corporation floor. Plan for fifteen to thirty minutes of additional time at these locations. Arriving at 4:30 p.m. at 28 Liberty Street for a same-day service with a 5:00 p.m. cutoff creates timing risk.

The designated intake representative. At CT Corporation offices, delivery must be made to the designated service of process intake representative — not to a receptionist, mailroom clerk, or building lobby security officer. CT Corporation maintains a specific intake procedure, and delivery to an unauthorized employee of the building or an adjacent floor does not constitute service. The server must confirm they are handing papers to a CT Corporation intake representative. For timing strategy across service methods, see our corporate process service timing guide.

Step 5 — Obtain and Retain the Written Receipt

CT Corporation logs every incoming service of process and generates a written receipt acknowledging the date, time, and entity for which service was accepted. The receipt is the contemporaneous third-party record of service — the document that corroborates the process server’s affidavit with an independent acknowledgment from the registered agent.

Always request the receipt before leaving. CT Corporation does not issue receipts retroactively. A server who delivers the papers and leaves without a receipt has no contemporaneous CT Corporation documentation — only the server’s own affidavit. While the affidavit alone may be legally sufficient in the relevant jurisdiction, the combination of the affidavit plus the CT Corporation receipt is the standard of documentation expected in commercial litigation, and the receipt significantly reduces the risk of a successful challenge to service. Undisputed Legal obtains and retains CT Corporation receipts as a standard step in every delivery.

What the receipt should contain. The CT Corporation receipt should reflect the entity name, the date and time of delivery, and the identity of the CT Corporation intake representative who accepted the papers. Confirm all fields before leaving the office. A receipt with a blank date field or an unreadable time stamp is a deficient receipt; ask the intake representative to complete or clarify before departing.

Step 6 — Prepare the GPS-Verified Affidavit of Service

The affidavit of service is the sworn document that creates the legal record of the service event. For CT Corporation delivery, the affidavit must accurately identify the service address (the specific CT Corporation office where delivery was made), the exact entity name served, the date and time of delivery, the manner of service (personal delivery to CT Corporation as registered agent), and the name of the CT Corporation intake representative who accepted the papers.

GPS-verified affidavit standard. A GPS-verified affidavit incorporates the GPS coordinates and timestamp recorded by the server’s device at the time of delivery, drawn from the device log maintained contemporaneously with the service event. For service in New York City’s five boroughs — including CT Corporation’s office at 28 Liberty Street in Manhattan — the affidavit includes the server’s active DCWP (Department of Consumer and Worker Protection) individual license number, as required by NYC Administrative Code § 20-403. The GPS coordinates place the server at the CT Corporation office at the stated time, creating an objective, tamper-resistant record that rebuts challenges to service validity.

What the affidavit confirms for counsel. The GPS-verified affidavit returned by Undisputed Legal identifies: the entity verification step (which SoS database was searched and what registered agent information was confirmed), the CT Corporation office served (full address), the server’s name and DCWP license number (for NYC service), the GPS coordinates and timestamp of delivery, the CT Corporation intake representative’s name, and the receipt reference. This is the complete documentation package for attaching to the court’s proof of service filing.

Step 7 — File Proof of Service Within the Required Deadline

Service is not complete from a procedural standpoint until proof of service is filed with the court within the required deadline. In New York state court, CPLR 306-b requires service to be completed within 120 days of filing, but CPLR 308(2) and 308(4) further require that the affidavit of service be filed with the court within 20 days of the service event for substituted service and nail-and-mail. For registered agent delivery (which is personal delivery to an authorized agent under CPLR 311), no separate filing deadline applies to the affidavit itself, but the 120-day overall service window under CPLR 306-b controls.

Federal court — FRCP 4(m). In SDNY and EDNY matters, FRCP 4(m) requires service to be completed within 90 days of filing the complaint. Service on CT Corporation as registered agent under FRCP 4(h)(1)(B) — delivery to an officer, managing agent, or general agent — is complete when the CT Corporation intake representative accepts the papers. The 90-day clock runs from the complaint filing date, not from when counsel orders service. For matters filed close to the limitations date, the FRCP 4(m) window should be tracked from day one.

Filing the proof of service. Attach the GPS-verified affidavit of service, the CT Corporation receipt, and the entity verification documentation to the proof of service filing. In federal court, the proof of service is filed as a separate document on the docket; in New York state court, it is filed with the clerk. For the complete entity-type service framework and filing procedures, see our how to serve business entities guide.

Common Mistakes — What Goes Wrong at Each Step

The seven steps above each have a specific failure mode. These are the most common errors Undisputed Legal sees when inherited matters arrive with defective CT Corporation service that needs to be corrected.

Step 1 failure — skipping verification. Serving at CT Corporation without confirming through the state entity database that CT Corp is the current registered agent for that specific entity. The most common result: papers delivered to CT Corp for an entity whose registered agent is actually CSC, producing non-service with no warning until the defendant challenges. Consult with legal counsel if registered agent status is in question before proceeding.

Step 2 failure — wrong office. Serving at the CT Corporation office closest to the courthouse rather than the address shown in the entity record. New Jersey (West Trenton, not Newark), California (confirm whether 818 W. 7th or Glendale), Delaware (CT Corporation System vs. Corporation Trust Company at 1209 Orange Street) — these are the three most common geographic errors that produce delivery to an office that cannot accept service for the entity in question.

Step 3 failure — wrong entity name. Presenting documents that use a trade name, DBA, abbreviation, or misspelled version of the entity’s legal name. CT Corporation’s intake system logs service by legal entity name; a mismatch creates a deficiency that can be raised by defense counsel.

Step 4 failure — off-hours delivery. Arriving after 5:00 p.m., on a holiday, or delivering to building lobby security rather than the CT Corporation intake desk. None of these constitute service on CT Corporation as registered agent.

Step 5 failure — leaving without receipt. The single most common and most easily preventable error. Always wait for and retain the written CT Corporation receipt before leaving the office.

Step 6 failure — incomplete affidavit. Affidavit that omits the CT Corporation intake representative’s name, uses the wrong service address, or lacks GPS verification data. In NYC five-borough matters, omitting the server’s DCWP license number is a documentation gap that can support a service challenge.

Step 7 failure — blown deadline. Completing service but failing to file proof of service within the applicable window, allowing the CPLR 306-b 120-day period or FRCP 4(m) 90-day period to run without a timely filing on record.

Top 10 CT Corporation Offices — Addresses and Notes

The addresses below are taken from current state entity database records and the comprehensive CT Corporation reference maintained in our complete CT Corporation service guide. Always verify the specific address through the relevant state entity search immediately before serving — registered office addresses can be updated by CT Corporation or by the entity’s registered agent designation filing at any time.

New York. CT Corporation System, 28 Liberty Street, New York NY 10005. Financial District, Manhattan. Lobby security — allow 15–30 minutes for sign-in and floor access. DCWP-licensed server required for five-borough service.

California. CT Corporation System, 818 W. 7th Street, Suite 930, Los Angeles CA 90017. Confirm whether the specific entity lists this address or the Glendale office (330 N. Brand Blvd, Suite 700, Glendale CA 91203) in the California Secretary of State entity search.

Delaware. Corporation Trust Company, 1209 Orange Street, Wilmington DE 19801. Note: the entity name in Delaware is Corporation Trust Company — not CT Corporation System. Confirm the exact registered agent name from the Delaware Division of Corporations entity record before addressing documents.

Texas. CT Corporation System, 1999 Bryan Street, Suite 900, Dallas TX 75201. Bryan Tower, Uptown Dallas. Standard walk-in service accepted during business hours.

Florida. CT Corporation System, 1200 S. Pine Island Road, Plantation FL 33324. Suburban Plantation, west of Fort Lauderdale. Not a high-rise location; parking available.

Illinois. CT Corporation System, 208 S. LaSalle Street, Suite 814, Chicago IL 60604. LaSalle Street financial corridor, downtown Chicago. Lobby security at this location — allow additional time.

New Jersey. CT Corporation System, 820 Bear Tavern Road, Suite 303, West Trenton NJ 08628. West Trenton — not downtown Trenton or Newark. Verify through the NJ Business Entity Search before dispatch.

Pennsylvania. CT Corporation System, 116 Pine Street, Suite 320, Harrisburg PA 17101. State capital Harrisburg — not Philadelphia or Pittsburgh. PA commercial litigation frequently involves Delaware-incorporated entities with the Harrisburg address as their PA registered agent.

Virginia. CT Corporation System, 4701 Cox Road, Suite 285, Glen Allen VA 23060. Richmond northern suburbs — not downtown Richmond or Northern Virginia. Eastern District of Virginia antitrust and federal procurement litigation regularly routes through this address.

Georgia. CT Corporation System, 289 S. Culver Street, Lawrenceville GA 30046. Lawrenceville (Gwinnett County), northeast of Atlanta. Verify through the Georgia Secretary of State Corporations Division — not an Atlanta address.

Frequently Asked Questions

What is the fastest way to confirm an entity currently uses CT Corporation as its registered agent?

Query the official Secretary of State entity search for the state where you intend to serve. Every state maintains a publicly searchable business entity database that shows the current registered agent name and registered office address. For New York: search.dos.ny.gov. For Delaware: corp.delaware.gov. For California: bizfileonline.sos.ca.gov. The search takes under two minutes. The result either confirms CT Corporation System (or Corporation Trust Company for DE) at the expected address, or reveals the current agent is someone else. Run this search every time — registered agents change without notice to the plaintiff.

Can I serve at any CT Corporation office, or must I use the office in the state where the entity is registered?

You must serve at the CT Corporation office listed as the registered agent's address in the state's entity records for the specific entity you are serving. CT Corporation operates separate legal entities and separate registered agent designations in each state. Serving at the New York office for a Delaware-incorporated entity does not accomplish service on that entity in Delaware; it is non-service. The correct office is the address shown in the current state entity record — verified immediately before serving. If an entity has registered agent designations in multiple states and you need service in more than one, each state's CT Corp office handles that state's service independently.

What happens if I deliver to a CT Corporation office outside normal business hours?

Delivery outside normal business hours does not constitute service on CT Corporation as registered agent. Leaving papers with building lobby security, sliding documents under the office door, or depositing papers in a building mailroom after CT Corporation staff have left for the day does not satisfy the personal delivery requirement. Service of process on a registered agent requires delivery to an authorized person at the registered agent's office during operating hours. The correct action if you arrive after hours is to return the next business day during operating hours. For same-day matters with tight afternoon deadlines, dispatch early to account for building security clearance time at high-rise locations.

How do I address the documents when serving through CT Corporation?

The entity's exact legal name — as it appears in the state entity records — followed by the registered agent identification: [Exact Legal Name of Entity], c/o CT Corporation System, [full address]. For Delaware entities where the registered agent is Corporation Trust Company, use that name instead: [Exact Legal Name of Entity], c/o Corporation Trust Company, 1209 Orange Street, Wilmington DE 19801. Do not use trade names, DBAs, abbreviations, or common-usage shortcuts in the entity name field on the documents. "ABC Corp" is a defect if the registered name is "ABC Corporation"; "XYZ LLC" is a defect if the registered name is "XYZ, L.L.C." Consult with legal counsel to confirm the correct entity identification before finalizing the documents.

Is DCWP licensing required to serve at CT Corporation's New York office at 28 Liberty Street?

Yes. CT Corporation's New York registered office at 28 Liberty Street is in Manhattan — one of New York City's five boroughs. NYC Administrative Code § 20-403 requires any individual who physically serves process in any of the five boroughs to hold an active DCWP individual process server license. This requirement applies to the server performing the walk-in delivery, regardless of where the server is based or how often they serve in the city. Service at 28 Liberty Street without a DCWP license is a misdemeanor and exposes the service to challenge as void or voidable. Undisputed Legal's servers hold active DCWP individual licenses for all five-borough service, including CT Corporation deliveries at 28 Liberty Street.

How long does it take for CT Corporation to forward papers to the entity after accepting service?

CT Corporation's internal forwarding time is typically one to three business days from acceptance of service. CT Corporation logs the incoming service, identifies the entity's internal legal or compliance contact, and transmits the documents electronically or by overnight courier depending on the entity's service preferences on file. However, the forwarding timeline does not affect when service is legally complete: service on CT Corporation as registered agent is complete when CT Corporation's intake representative accepts the papers during business hours. The entity's actual receipt of the forwarded papers affects when the defendant's answer period begins, not when the plaintiff's service is made for limitations or CPLR 306-b purposes.

What is the difference between CT Corporation System and Corporation Trust Company in Delaware?

Both are Wolters Kluwer subsidiaries that operate registered agent services, but they are distinct legal entities and appear under different names in Delaware's entity records. Corporation Trust Company is the original Delaware entity — founded in 1899 and operating at 1209 Orange Street, Wilmington DE 19801 — which is listed as registered agent for many older Delaware-incorporated companies. CT Corporation System is the separate entity that appears as registered agent for companies that designated CT Corp under its current operating name. When preparing documents for Delaware service, use the exact registered agent name shown in the Delaware Division of Corporations entity record for the specific company being served. Directing delivery to "CT Corporation" at 1209 Orange Street when the registered agent record shows "Corporation Trust Company" creates a potential deficiency in the affidavit.

What if CT Corporation refuses to accept service for an entity?

CT Corporation's intake desk may decline papers if the entity name does not match its records (suggesting CT Corp is not the current agent for that entity), if the documents are incomplete, or if the presentation is made outside business hours. A refusal at intake means service has not been made and the server must investigate before re-attempting. First, re-verify the entity's current registered agent through the state entity search — if CT Corp has been replaced, identify the current agent. Second, if CT Corp is confirmed as the current agent, review the document preparation for entity name accuracy and completeness. Do not re-attempt delivery without resolving the underlying issue; a second failed delivery wastes time without advancing service. For entities with no current registered agent (resigned without replacement, administratively dissolved), see our New York Secretary of State service guide and process service laws guide for the applicable fallback mechanisms.
