Personal Injury Lawsuit Process: From Accident to Settlement

The Numbers Behind Personal Injury Claims

More than 400,000 tort cases are filed in U.S. state courts each year, making personal injury litigation one of the most common forms of civil court activity. Yet fewer than 5% of personal injury claims ever reach trial — the overwhelming majority resolve through pre-suit negotiation or post-filing settlement. Understanding the full process from accident to resolution helps injured parties make informed decisions about whether to file, when to accept a settlement, and what to expect at each stage.

Personal injury law is grounded in the common law of negligence: to recover damages, a plaintiff must prove that the defendant owed a duty of care, breached that duty, and that the breach was the proximate cause of the plaintiff's damages.

Step 1 — Seek Medical Treatment and Document Everything

Documentation begins at the accident scene. Every piece of evidence secured in the first 72 hours has outsized value later. Essential immediate actions:

• Call 911 and obtain a police or incident report number.
• Photograph the scene, any visible injuries, property damage, and contributing hazards.
• Collect names, contact information, and insurance details from all parties and witnesses.
• Seek medical evaluation the same day, even if injuries seem minor — delayed-onset injuries such as whiplash and traumatic brain injury are well-documented and insurers will use gaps in treatment against claimants.
• Begin a written injury journal documenting daily pain levels, limitations on activities, and medical appointments.

Medical records are the evidentiary backbone of any personal injury claim.

Step 2 — Consult a Personal Injury Attorney

Most personal injury attorneys work on contingency — typically 33% of any pre-suit settlement, rising to 40% if the case proceeds to trial. The consultation is free. The attorney will evaluate liability, assess damages, investigate coverage, and advise on whether a claim is worth pursuing. Attorneys investigate police reports, obtain surveillance footage (which may be overwritten in days), and preserve electronic data critical to proving fault.

Step 3 — The Demand Letter

Once the injured party reaches maximum medical improvement (MMI) — the point at which the treating physician determines recovery has plateaued — the attorney compiles a demand package and sends a formal demand letter to the insurance carrier. The demand letter includes:

• A narrative of the accident and liability argument
• Complete medical records and billing documentation
• Proof of lost wages and out-of-pocket expenses
• A demand for a specific dollar amount
• A response deadline (typically 30 days)

Many cases settle at this stage.

Step 4 — Filing the Lawsuit and Statute of Limitations

If the insurance carrier denies liability or makes an inadequate offer, the plaintiff's attorney files a complaint in the appropriate court. The statute of limitations — the deadline to file — varies by state and claim type:

Filing tolls (pauses) the statute of limitations. After filing, the defendant is served with the complaint and has 20–30 days to respond.

Step 5 — Discovery

Discovery is the pre-trial information exchange between parties. It typically lasts 6–18 months in personal injury cases. Key discovery tools include:

• Interrogatories: Written questions requiring written answers under oath.
• Depositions: Oral testimony under oath before a court reporter; parties, witnesses, and experts may be deposed.
• Requests for Production: Demands for documents, photographs, electronic data, and insurance policies.
• Independent Medical Examinations (IME): Defendants are entitled to have the plaintiff examined by a physician of their choosing.
• Expert discovery: Both sides disclose expert witnesses (accident reconstructionists, medical experts, economists) who will testify at trial.

Step 6 — Mediation and Settlement Negotiations

Most jurisdictions require or strongly encourage mediation before trial. A neutral third-party mediator facilitates negotiation. Mediation is non-binding — either party can walk away. Approximately 70–80% of personal injury cases that reach mediation settle on the mediation date or shortly after.

Step 7 — Trial

Trial is the exception, not the rule. A personal injury trial typically lasts 3–7 days. The plaintiff bears the burden of proof by a preponderance of the evidence — more likely than not (greater than 50%). Contributory and comparative negligence rules affect recovery: in pure comparative negligence states (e.g., California, New York), a plaintiff 99% at fault can still recover 1% of damages; in modified comparative negligence states (most states), plaintiffs barred at 50% or 51% fault.
