Washington State Personal Injury Statute of Limitations

Most personal injury lawsuits in Washington must be filed within three years of the date you were hurt, but the Washington state personal injury statute of limitations is actually a set of different deadlines that depend on what type of claim you have and who caused the harm. Some claims shrink to two years. Medical cases run on a dual clock with an eight-year ceiling. Government claims add a mandatory waiting period. And a handful of situations pause the deadline entirely. Miss the one that applies to you, and the case is gone no matter how badly you were injured.

The Three-Year Default

For the majority of injury claims, you have three years from the date of injury to file suit.¹ That covers car and bicycle crashes, slip-and-fall injuries, dog bites, and the general run of accidents caused by someone else’s carelessness.

The clock starts on the exact day of the injury. Hit by a car on March 10, 2024? Your complaint must be on file by March 10, 2027. Talking with an insurance adjuster does not stop the clock. Only filing a lawsuit (or formally serving the defendant) does.² It is common for people to spend months in settlement talks, assume there is still plenty of time, and realize too late that the deadline passed during those conversations.

One procedural trap: filing alone is not always enough. If you file first, you must serve the defendant within 90 days. If you serve first, you must file within 90 days. Blow that 90-day window and the lawsuit is treated as if it never started.²

Two Years for Assault, Defamation, and False Imprisonment

Not every injury gets the full three years. Claims for assault, battery, false imprisonment, libel, and slander must be filed within two years.³ The shorter window applies even when an intentional attack causes serious physical injuries. Someone who was beaten and hospitalized still has only two years from the date of the assault to sue the attacker.

Defamation runs on the same two-year clock whether the false statement was written or spoken.³ Because people often don’t learn about defamatory statements right away, that compressed timeline can turn urgent fast once the harm surfaces.

Medical Malpractice: Two Clocks and a Ceiling

Injuries caused by healthcare providers follow their own rules under RCW 4.16.350. You must file within three years of the negligent act, or within one year of the date you discovered (or reasonably should have discovered) that the injury was caused by negligent care, whichever is later.⁴

The one-year discovery window matters most when a medical error is not immediately obvious. A surgical sponge left inside a patient, or a misdiagnosis that progresses slowly, might not come to light for years. In those cases the one-year clock does not begin until a reasonable person would have connected the injury to the care.

Washington also imposes an absolute eight-year cap. No medical malpractice lawsuit may be filed more than eight years after the negligent act, no matter when the patient discovered the harm.⁴ That ceiling applies even to patients who had no realistic way of detecting the error inside the eight-year window.

Wrongful Death and Survival Actions

When someone dies because of another person’s negligence, the family generally has three years from the date of death to file a wrongful death lawsuit. The clock runs from the death itself, not from the date of the underlying negligent act. That matters in cases where, for example, a medical error occurs in one year but the patient does not die from it until two years later.

Washington also recognizes survival actions, which preserve the claims the deceased could have brought while alive. Under RCW 4.20.046, those claims pass to the personal representative of the estate. One important limit: the personal representative cannot recover for pain, suffering, or emotional distress the deceased experienced before death.⁵ Economic losses like pre-death medical bills can still be recovered through the survival claim; the emotional damages belong to the family’s wrongful death case.

Childhood Sexual Abuse

Survivors of childhood sexual abuse get an extended window. Under RCW 4.16.340, suit may be filed within three years of whichever of the following comes latest:

the abusive act itself
the victim’s 18th birthday
the date the victim discovered or reasonably should have discovered that the abuse caused their injury
the date a licensed healthcare professional diagnosed the victim’s condition as resulting from childhood sexual abuse

The “whichever is latest” structure means the most generous of the four controls. It reflects the reality that many survivors do not connect their injuries to the abuse until well into adulthood, sometimes after years of therapy. The statute applies retroactively to claims that were previously time-barred.⁶

Product Liability

If a defective product causes an injury, Washington applies a rebuttable presumption that the product has exceeded its useful safe life once 12 years have passed since first delivery to a buyer.⁷ This is not an absolute bar like the medical malpractice ceiling. It shifts the burden: the manufacturer gets the presumption, and the injured person has to overcome it with evidence. That makes the case significantly harder to win.

For injuries that happen inside the 12-year window, the normal three-year personal injury deadline still applies.

Claims Against Government Entities

Suing a Washington government agency adds a required step before any lawsuit. You first have to submit a standard tort claim form, and a mandatory 60-day waiting period runs before you can file in court.⁸ Claims against the state go to the Office of Risk Management. Claims against counties, cities, school districts, and other local entities go to a designated agent each local government must appoint and register with the county auditor.⁹

The underlying statute of limitations still applies on top of that. The tort claim form must be delivered within the same three-year window (or shorter, if your claim type calls for one), and a late form kills the case the same way a late lawsuit does. Because the form takes time to prepare and the 60-day wait eats into your timeline, starting early is more important than it looks.

When the Clock Starts Late: The Discovery Rule

Some injuries are not apparent when the negligent act occurs. Washington courts apply a discovery rule that delays the start of the limitations clock until the injured person knew, or reasonably should have known, both that they were injured and what caused it.

Toxic exposure cases are the standard illustration. Someone who worked around hazardous chemicals for years may not develop symptoms until long after exposure ended. The three-year clock does not start on the day of exposure. It starts when a reasonable person in the same position would have connected the health problems to the exposure. The test is objective, not what this particular plaintiff happened to notice.

Occupational diseases handled through workers’ compensation have their own trigger. Under RCW 51.28.055, a worker has two years to file a claim starting from the date they receive written notice from a physician that the occupational disease exists and that a workers’ compensation claim may be filed.¹⁰ The written notice from a doctor is the trigger, not the date of exposure or the date the disease first developed.

Tolling for Minors and Incapacitated People

The statute of limitations can be paused for people who lack the legal capacity to sue on their own. Under RCW 4.16.190, time spent as a minor (under 18) or as someone too incapacitated to understand legal proceedings does not count against the deadline.¹¹

For personal injury specifically, Washington caps that tolling two ways. The disability cannot pause the clock for more than five years total, and it cannot extend more than one year past the date the minor turns 18 or the incapacitated person regains capacity. Whichever cap arrives first wins.¹¹

This creates a trap for parents of young children. A teenager injured at 16 effectively has until around age 22 to file. But a child injured at age two hits the five-year cap at age seven, well before turning 18, which means the three-year clock then runs and expires at age ten. Waiting until the child turns 18 is not always safe. A parent or guardian must file on the child’s behalf before the capped deadline runs.

Other Situations That Pause the Clock

If the person you need to sue leaves Washington or hides within the state, that time does not count against your deadline.¹² A defendant cannot run out the clock by disappearing.

A lawsuit filed in good faith and later dismissed for a procedural reason also typically preserves additional time to refile. The specifics turn on the circumstances of the dismissal, but a technical defect does not usually destroy an otherwise valid claim.

What Happens If You File Late

If the deadline passes before you file, the defendant will raise the statute of limitations as a defense and the court will almost certainly dismiss. Judges have very little discretion to grant exceptions beyond the tolling and discovery rules already written into the statutes. The severity of your injuries, the strength of your evidence, and the clarity of the defendant’s fault stop mattering once time runs out.

Insurance companies understand this and sometimes let negotiations drift for exactly that reason. Keep your filing deadline on a calendar, tracked independently of any settlement conversation. That one habit is the single most important thing you can do to protect the claim.
