Time Limits for Serving a Personal Injury Lawsuit in New York

The Second Deadline That Can End a Personal Injury Case

Commencing a personal injury lawsuit is only the first procedural step toward civil recovery. Filing the Summons and Complaint with the court clerk officially begins the action and stops the statute of limitations clock, but it does not notify the defendant, and it does not compel anyone to appear in court. A second, independent countdown starts the moment the papers are filed, and missing this deadline can cause an otherwise valid case to be dismissed before it ever reaches a courtroom. Under New York law, the plaintiff bears the responsibility of formally delivering those papers to the defendant.

CPLR 306-b: The 120-Day Service Rule

New York Civil Practice Law and Rules ("CPLR") § 306-b sets three specific requirements governing when and how the Summons and Complaint, the official pleading that names the responsible parties and details the injuries and claims being asserted, must reach each defendant named in the action.

New York recognizes several methods of accomplishing this, including personal delivery directly to the defendant, substitute service on a person of suitable age and discretion at the defendant's home or place of business followed by mailing, and service on an authorized agent. Whichever method is used, the delivery must satisfy the specific procedural requirements that govern that method.

The failure to serve the defendants within the time frame is not always deadly to the case. As long as the case is within the statute of limitations, the Summons & Complaint can be re-filed and then another 120-day window starts. This becomes a problem when the statute of limitations passes and a new Summons & Complaint cannot be filed. This is another example showing the importance of being proactive in filing of papers, especially a Summons & Complaint.

1. The 120-Day General Window

A plaintiff has exactly 120 days from the date the lawsuit is filed with the court clerk to serve every named defendant named in the lawsuit. The clock runs from the date of filing regardless of how difficult service proves to be or how many defendants are named in the complaint. Each defendant must be served within that window.

2. The Shortened 15-Day Exception

Most personal injury claims are governed by a three-year statute of limitations and fall entirely within the standard 120-day window. The 15-day exception applies only to claims with a limitations period of four months or less. A plaintiff who has filed a Notice of Claim against a municipality and then commenced a lawsuit near the expiration of the applicable one-year-and-ninety-day period, for example, may face a compressed service window that leaves little time to locate and serve the defendant before the deadline arrives. Service must be completed no later than 15 days after the underlying limitations period expires.

3. Proof of Service: The Affidavit of Service

Delivering the papers to the defendant is not enough on its own. The process server must execute a notarized Affidavit of Service confirming that delivery occurred in compliance with New York's recognized methods and file it with the court. Without that sworn record, a plaintiff cannot prove service took place.

Common Service of Process Problems

Formal service of process is rarely as straightforward as delivering paperwork to a known address. Three recurring scenarios consistently cause plaintiffs to lose the service window, and in many of those cases the underlying injury claim.

1. The Evasive Defendant

Defendants who anticipate a lawsuit sometimes take deliberate steps to make service difficult. Drivers involved in serious accidents move without updating their address with the DMV. Out-of-state trucking companies route their registered agents through states with slow service rules. Small business owners close their storefronts or restructure their entities after an incident to complicate service on the legal entity. In each situation, the process server encounters a defendant who is either genuinely difficult to locate or actively avoiding the paperwork, and the 120-day window continues to run regardless of how many attempts have been made.

2. The Last-Minute Filing

If a lawsuit commences close to the end of the limitations period, there is little room for error if initial service attempts fail. The limitations period will have expired long before any service problems surface, meaning there is no option to refile if the window closes without a successful delivery.

3. Dismissal After the Limitations Period Has Run

CPLR § 306-b requires the court to dismiss the action without prejudice when service is not made within the statutory period. "Without prejudice" is a procedural designation that normally preserves the right to refile. When the statute of limitations has already expired by the time that dismissal is entered, the right to refile no longer exists. The dismissal is technically "without prejudice," but the consequence is permanent: the case is gone. This is the mechanism by which a procedural failure transforms into a complete forfeiture of the right to compensation, regardless of how severe the injuries were or how clearly liable the defendant was.

Saving an Untimely Case: The "Interest of Justice" Extension

A missed or expiring service deadline is not automatically fatal. CPLR § 306-b grants New York courts the authority to extend the service window when a defendant moves for dismissal or when a plaintiff files a motion seeking additional time before the deadline expires. Courts evaluate those requests under one of two distinct legal standards, depending on the circumstances of the service failure.

Good Cause Shown

The first standard requires the plaintiff to demonstrate that continuous, diligent, and reasonable efforts were made to locate and serve the defendant, but that those efforts were derailed by circumstances outside the plaintiff's control. A process server who makes repeated attempts at a defendant's last known address, conducts database searches for updated contact information, and attempts service at a known workplace before the deadline expires has likely built a sufficient record to support a good cause application. A plaintiff who failed to hire a process server promptly, or whose attorney lost track of the deadline, has not. Good cause is the more demanding of the two standards, and courts applying it focus almost entirely on the diligence of the plaintiff's service efforts and the nature of the obstacle that prevented completion.

The Interest of Justice Standard

The New York State Court of Appeals established a broader equitable safety net for cases that cannot satisfy the good cause requirement. Under the interest of justice standard, courts are not limited to evaluating the plaintiff's diligence. Judges may weigh multiple factors simultaneously, including the legal merit of the underlying injury claim, whether the defendant had actual notice of the lawsuit or the underlying accident through insurance investigators, medical records requests, or other channels, the length of the delay in completing service, and whether a dismissal would deprive the plaintiff of any realistic path to recovery because the limitations period has already expired.
