What Is the Medical Malpractice Statute of Limitations in Washington State?
If you or a loved one was harmed by a doctor, hospital, or other healthcare provider in Washington, time is not on your side. Every state sets a strict deadline—called a statute of limitations—for filing a medical malpractice lawsuit. Miss it, and you almost certainly lose your right to recover any compensation, no matter how strong your case is.
This article explains Washington's rules in plain English so you know where you stand. If you're unsure about your specific situation, connect with our free AI intake tool to get pointed in the right direction.
Washington's Basic 3-Year Rule
Under RCW 4.16.350, Washington gives most medical malpractice victims three years from the date the negligent act occurred to file a lawsuit. This is the baseline rule.
Example: If a surgeon performed a negligent procedure on March 1, 2022, you would generally need to file your lawsuit by March 1, 2025.
Three years may sound like plenty of time, but medical malpractice cases are complex. Gathering medical records, finding expert witnesses, and working through the legal process all take months. Many attorneys recommend reaching out as early as possible.
The Discovery Rule: When You Didn't Know Right Away
Sometimes you don't realize you were harmed by malpractice until long after the original treatment. Washington law accounts for this through the discovery rule.
Under RCW 4.16.350, the three-year clock can start from the date you discovered—or reasonably should have discovered—the injury, rather than the date of the negligent act itself.
However, there is an important ceiling called the statute of repose: Washington caps the total time at eight years from the date of the act or omission, regardless of when you discovered the harm. In other words:
- You have 3 years from discovery, OR
- 8 years from the date of the negligent act—whichever comes first.
If a doctor's mistake is discovered nine years later, you may be legally barred from filing even if you had no way to know earlier. This makes acting quickly essential once you suspect malpractice.
Special Exceptions That Can Change Your Deadline
Washington law includes several exceptions that may extend or alter the standard deadline:
Minors (Children Under 18)
If the victim is a minor at the time of the malpractice, special tolling rules apply. Generally, the statute of limitations does not begin to run until the child turns 18. However, the 8-year statute of repose still applies—and for injuries at birth, this can be complicated. Confirm the exact deadline with an attorney.
Fraud or Concealment
If a healthcare provider actively concealed the malpractice or fraudulently misled you, Washington courts may toll (pause) the statute of limitations during the period of concealment.
Foreign Objects Left in the Body
For cases involving a foreign object left inside a patient (such as a surgical sponge or instrument), the discovery rule typically governs—the clock starts when you find out or reasonably should have found out about the object.
Death of the Victim
If the victim dies as a result of the malpractice, surviving family members may file a wrongful death or survival action claim. These have their own filing deadlines—confirm with an attorney as soon as possible.
Washington's Pre-Suit Notice Requirement
Washington is one of several states that requires a pre-suit notice before you can formally file a medical malpractice lawsuit. Under RCW 7.70.100, you must give the healthcare provider at least 90 days' written notice of your intent to file a claim.
This notice period is not a replacement for the statute of limitations—it runs alongside it. What this means practically:
- You may need to send the notice at least 90 days before your deadline expires.
- If you wait until the last moment to contact an attorney, there may not be enough time to meet this requirement properly.

Why Acting Quickly Matters in WA Malpractice Cases
Beyond the legal deadlines, there are practical reasons to move fast:
- Medical records can be lost or altered over time.
- Witnesses' memories fade, and key staff may leave a hospital or clinic.
- Expert witnesses are in high demand and require lead time to retain.
- Building a strong case takes months, and attorneys need time to evaluate it before filing.
Even if you're unsure whether what happened qualifies as malpractice, it costs nothing to get an initial review.
Frequently Asked Questions
How long do I have to sue a doctor in Washington State?
In most cases, you have 3 years from the date of the negligent act—or from when you discovered (or should have discovered) the injury. An 8-year absolute cap applies regardless of discovery.
Does the statute of limitations pause if I'm still treating with the same doctor?
Washington does not have an automatic tolling rule for ongoing treatment relationships, unlike some other states. Do not assume your clock is paused—consult an attorney promptly.
What if a loved one died due to medical negligence in Washington?
Wrongful death and survival claims have their own deadlines. Generally, the deadline for a wrongful death claim in Washington is 3 years from the date of death under RCW 4.16.080. Confirm specifics with an attorney.
Can I still file a claim if the hospital is government-owned?
If the provider works for a government entity (such as a VA hospital or public university medical center), you may need to file a separate administrative claim first, and different deadlines may apply. This area is complex—speak with an attorney immediately.
What counts as medical malpractice in Washington?
Medical malpractice occurs when a healthcare provider fails to meet the accepted standard of care and that failure causes you harm. Common examples include misdiagnosis, surgical errors, medication mistakes, and failure to obtain informed consent.
