How a Car Accident Lawsuit Works in New York: From Summons to Verdict

Most New York car accident claims never become lawsuits. They settle in negotiation, quietly, on paper. But when the insurer will not pay what the case is worth, or when the statute of limitations is closing, a car accident lawsuit is the only remaining leverage. Understanding what that process actually looks like, step by step, removes most of the fear attached to the word.

This guide walks through a New York car accident lawsuit from the day the summons is filed to the day a jury returns a verdict, including the stages where most cases quietly resolve along the way.

Filing Suit Is Not the First Step

A lawsuit is not how a claim begins. In New York, a car accident case starts with the No-Fault system, which pays medical bills and a portion of lost earnings regardless of who caused the crash. That claim has its own deadline: written notice to the insurer within 30 days of the accident. Filing suit does not replace that obligation, and missing it can cost you benefits even in a case you eventually win.

Litigation begins only after two things are clear. First, that your injuries meet the serious injury threshold in New York Insurance Law § 5102(d), which is what allows you to sue for pain and suffering at all. Second, that the insurer’s best offer is meaningfully below what the case should produce. If you have not yet been through the first stage of a claim, start with our guide on what to do after a car accident in Queens.

The Deadline That Ends Cases Before They Start

New York gives you three years from the date of the crash to file a personal injury lawsuit under CPLR § 214. Wrongful death is shorter, at two years. Claims against a city, the MTA, or another public entity are shorter still, and require a Notice of Claim within 90 days.

These deadlines are jurisdictional. A judge who likes your case and believes every word of it will still dismiss it if the summons was filed a day late. We cover the narrow exceptions in our guide to missing the statute of limitations in New York, but the honest summary is that the exceptions rarely apply.

Stage One: Summons and Complaint

The lawsuit formally begins when your attorney files a Summons and Complaint with the County Clerk and pays the index number fee. In Queens, that filing goes to Queens County Supreme Court. The Complaint states who the parties are, what happened, what duty the defendant owed, how it was breached, and what injuries followed.

The defendant then has a set period to serve an Answer, which typically denies almost everything and asserts a list of affirmative defenses, including comparative fault. That denial is procedural, not personal. It does not mean the insurer thinks you are lying, and it does not signal how the case will end.

New York is a pure comparative negligence state, so even a plaintiff found substantially at fault can still recover a reduced share. Our explanation of comparative negligence in New York covers how that arithmetic works.

Stage Two: Discovery, Where Cases Are Actually Won

Discovery is the longest phase and the one that decides most outcomes. Both sides exchange documents, written questions, medical records and sworn testimony. For a car accident case this usually includes:

• Bill of Particulars. A detailed written statement of exactly which injuries you claim and how they limit you. This document constrains the rest of your case, so it is drafted carefully.
• Document exchange. Police reports, photographs, repair estimates, medical records, wage records, and increasingly vehicle telematics and phone data.
• Depositions. Sworn out-of-court testimony from you, the other driver, and any witnesses. Our guide on what happens after your deposition explains what follows.
• Independent Medical Examination. An exam by a doctor the defense selects and pays. It is not independent in any ordinary sense. See our breakdown of the No-Fault IME and how benefits get cut off.

Discovery is also where the defense builds its attack on your credibility. Gaps in your treatment record and your social media both get scrutinized, which is why we cover gaps in treatment and social media in New York injury claims separately. What you sign matters too, which is why we advise caution before giving an insurer access to your medical records.

Stage Three: Motions and the Threshold Fight

When discovery closes, the defense will often move for summary judgment under CPLR § 3212, arguing that your injuries do not clear the serious injury threshold and that the case should be dismissed without a trial.

This is the pivotal motion in New York car accident litigation. It is won or lost on medical proof: objective imaging, quantified range-of-motion findings, and a treating physician’s opinion connecting the injury to the crash. Cases with real injuries are lost here every year because the medical record was thin or the narrative reports were generic. It is also why surgery is not the dividing line people assume, as we explain in our guide to back and neck injury settlements without surgery.

Stage Four: Trial, and the Settlements That Precede It

If the case survives summary judgment, it is placed on the trial calendar. Court-annexed mediation and settlement conferences follow, and the great majority of cases resolve here. The insurer’s valuation changes once a trial date is real and defense costs start accruing.

If it does go to verdict, a jury decides liability, apportions fault, and awards damages for medical expenses, lost earnings, and pain and suffering. New York appellate courts review awards against what is reasonable compensation for comparable injuries, which is the closest thing the state has to a valuation yardstick. Our post on pain and suffering settlement examples explains how that comparison actually works, and why the multiplier method you read about online is not New York law.

A verdict is also not the last step. Liens, case costs and attorney fees come out before you see anything, which we walk through in how much of a settlement you actually keep.

How Long Does It Take?

A New York car accident lawsuit that goes the distance commonly runs two to four years from filing, depending on the county’s calendar, the complexity of the injuries, and how aggressively the defense litigates. Queens County carries a heavy civil docket. Cases that settle during discovery or at a pre-trial conference resolve considerably faster.

Frequently Asked Questions

Do I have to go to court if I file a car accident lawsuit?

Almost certainly you will attend a deposition, and possibly an independent medical examination and a settlement conference. Most plaintiffs never testify in front of a jury, because the overwhelming majority of filed cases resolve before trial. Filing suit is better understood as applying pressure than as committing to a courtroom.

Will filing a lawsuit make the insurance company fight harder?

It changes their arithmetic rather than their attitude. Once suit is filed, the carrier begins paying defense counsel and faces the risk of a verdict above the policy limits. In many cases that pushes the offer up rather than down.

What if the other driver was uninsured?

You may still have a claim through your own uninsured or underinsured motorist coverage, or through MVAIC if no coverage exists anywhere. These have their own short deadlines, which we cover in our guide to uninsured and underinsured motorist claims.

Can I file a lawsuit if I was partly at fault for the crash?

Yes. New York applies pure comparative negligence, so your recovery is reduced by your percentage of fault rather than eliminated. A plaintiff found 40 percent responsible still recovers 60 percent of the damages awarded.

Does the property damage claim have to be settled first?

No, and the two should be kept separate. Property damage releases sometimes contain language broad enough to compromise the injury claim, which we flag in our guide to total loss and property damage claims.

How much does it cost to file a car accident lawsuit?

Personal injury firms in New York work on contingency, so there is no hourly fee. Case costs such as the index number fee, expert witness fees and deposition transcripts are typically advanced by the firm and reimbursed from the recovery. Contingency fees in New York are regulated by court rule.
