Car Accident Lawsuit: When a Claim Becomes a Case, Step by Step

Every injury claim starts as a negotiation with an insurance adjuster. A lawsuit is what happens when that negotiation fails or runs out of time. The common triggers are an insurer that denies its driver was at fault, an offer that does not cover the medical bills, a dispute about whether the injury came from the crash, and a statute of limitations that is about to expire while the parties are still talking.

Filing suit changes the dynamic. The insurer now has to pay a defense lawyer by the hour, produce its file, and face the possibility of a verdict above what it offered. Adjusters have more settlement authority once a case is in litigation, and the person evaluating the file often changes from a claims adjuster to a litigation specialist with a different view of risk.

It is normal for a case to be filed and settled a year later without ever being seen by a judge in any meaningful way. Filing is a tool to get a fair valuation, not a commitment to trial.

The named defendant is the driver who caused the crash, and sometimes the owner of the vehicle, the driver's employer if they were working, or a company responsible for a defective part or dangerous road. You generally cannot name the insurance company as a defendant in most states, and juries are often not told that insurance exists.

In practice, the driver's liability insurer controls the defense. It chooses and pays the lawyer, decides whether to settle, and pays any judgment up to the policy limit. The driver usually has little involvement beyond giving a deposition and showing up for trial. If a verdict exceeds the policy limit, the driver is personally responsible for the excess, which is one reason insurers settle serious cases within limits.

Finding out the policy limit early matters. A $25,000 policy on a case with $100,000 in medical bills changes the strategy entirely, pointing toward your own underinsured motorist coverage or other defendants rather than a long fight over a number the insurer cannot pay.

The case begins with a complaint, a document filed in court stating what happened, why the defendant is responsible, and what you are asking for. The defendant is served and files an answer, usually denying most of it and raising defenses such as your own negligence. In some states a pre-suit notice or demand period is required before filing.

Discovery follows and takes up most of the case. Each side sends written questions called interrogatories, requests for documents, and requests for admissions. Each side takes depositions, which are question-and-answer sessions under oath with a court reporter present. Your treating doctors may be deposed. The defense will usually have you examined by a doctor it chooses, called an independent medical examination, though it is paid for by the defense.

After discovery, the lawyers file motions, the court often orders mediation with a neutral third party, and a trial date is set. Mediation after discovery is where the majority of filed cases settle, because by then both sides know what the evidence looks like. If mediation fails, the case is tried to a jury or a judge, and the losing side may appeal.

Suppose a driver ran a stop sign and hit you in March, leaving you with a fractured wrist that needed surgery. Treatment ended in November with $45,000 in medical bills and $8,000 in lost wages. Your attorney sent a demand in December. The insurer offered $30,000 in February, arguing you were partly at fault because you were speeding. Your state has a two-year deadline, so there is time, but the gap is too large to bridge by phone.

The complaint is filed in April, thirteen months after the crash. The answer comes in May. Written discovery runs through the summer. You are deposed in October, the other driver in November. The defense doctor examines you in January and writes a report saying your wrist has healed fully. Your surgeon's deposition in March says you have permanent loss of grip strength.

Mediation is set for May, about 26 months after the crash. With the surgeon's testimony on the record and a witness who confirms the stop sign was run, the insurer's valuation has moved. The case settles at mediation for a figure well above the February offer, and the money is paid within about a month. All numbers here are illustrative; the point is the sequence and the way discovery moved the number.

Litigation asks more of you than a claim does. The work is not difficult, but it is unavoidable and the case suffers when it is done carelessly.

• Answer written interrogatories accurately and completely, including questions about prior injuries, prior claims, and prior lawsuits; omissions are found and used.
• Sit for a deposition, usually lasting two to four hours, after preparation with your attorney; answer only the question asked, and say you do not know when you do not.
• Attend the defense medical examination and describe your symptoms consistently with what you have told your own doctors.
• Preserve everything: photos, messages, social media, the damaged vehicle if possible, and receipts.
• Keep treating as your doctors recommend; a gap in treatment during litigation is argued as proof of recovery.
• Stay off social media about the crash, your injuries, and your activities until the case ends.

The deadline to file is set by each state's statute of limitations for personal injury, and it is strict. Tennessee and Kentucky allow one year from the crash. Texas, California, Florida and Georgia allow two years. New York and North Carolina allow three. Missing the deadline ends the claim regardless of how strong it was, and the insurer has no reason to settle a claim that can no longer be filed.

Fault rules decide how much a jury can award. In pure comparative negligence states such as California and New York, you can recover even if you were mostly at fault, reduced by your share. Most states use modified comparative negligence with a 50 or 51 percent cutoff. Alabama, Maryland, North Carolina and Virginia follow contributory negligence, under which any fault on your part can defeat the claim, which makes the fault evidence in those states decisive.

No-fault states limit when you can sue at all. In Florida, Michigan, New York and New Jersey, a lawsuit against the at-fault driver for pain and suffering is allowed only if the injury meets a statutory threshold, such as permanent injury or significant disfigurement. Some states also cap non-economic damages in certain cases, and a few require pre-suit notice when the defendant is a government entity, often within months of the crash.

Most personal injury attorneys work on contingency, taking a percentage of the recovery and nothing if there is none. The percentage commonly rises once a lawsuit is filed, because the work multiplies. Read the fee agreement for the exact figures and for how case costs are handled.

Case costs are separate from the fee. Filing fees, deposition transcripts, expert witness fees and medical record charges add up, and in a case with multiple experts they can reach tens of thousands of dollars. Most firms advance these and recover them from the settlement. Ask whether costs come out before or after the percentage is calculated, because the difference affects what you take home.

If you lose at trial, you generally do not pay the other side's attorney fees in the United States, but some states have offer-of-judgment rules under which rejecting a formal settlement offer and then doing worse at trial can make you liable for certain defense costs. Your attorney should explain this before any formal offer is rejected.

A lawsuit makes sense when the gap between the offer and a fair value is large enough to justify a year or more of process, when the injury is serious enough that the evidence will hold up under discovery, and when there is insurance or assets to collect from. It makes less sense for a minor injury where the dispute is a few thousand dollars, and small claims court exists for the smallest cases.

The decision is one an attorney has to make with you on the specific facts, because it depends on the policy limits, the strength of the fault evidence, your medical history, and the venue.
