Lawsuit Steps in Washington
Hire an Attorney
Most personal injury attorneys in Washington work on contingency — no upfront fees. They evaluate your case and advise on whether litigation makes sense.
Investigation & Evidence
Your attorney gathers medical records, accident reports, witness statements, and expert opinions to build the strongest possible case.
Demand & Negotiation
Before filing suit, your attorney typically sends a demand letter and attempts settlement. Most cases resolve without going to court.
File the Complaint
If negotiations fail, your attorney files a complaint in the appropriate Washington court. You must file within 3 years of the injury.
Discovery
Both sides exchange evidence, take depositions, and may hire expert witnesses. Discovery typically takes 6–18 months.
Mediation / Trial
Most cases settle during or after discovery. If not, your case goes to trial before a judge or jury under Washington court rules.
Key Washington Law Facts
Washington State uses pure comparative fault under RCW § 4.22.005 — injured plaintiffs can recover damages regardless of their percentage of fault, with the award reduced proportionally by the plaintiff's assigned share of responsibility for the accident.
Personal injury lawsuits in Washington must be filed within 3 years from the date of injury or discovery under RCW § 4.16.080; the discovery rule applies for latent injuries, and claims against governmental entities require a specific pre-claim notice procedure.
Washington does not require no-fault personal injury protection insurance as part of mandatory auto coverage, though PIP is available as optional coverage; Washington operates as a traditional at-fault tort state for personal injury claims involving vehicle accidents.
