What Is the Medical Malpractice Statute of Limitations in Washington State?
If you or a loved one suffered harm because of a doctor, nurse, or hospital in Washington, time is not on your side. Missing a legal deadline can permanently bar you from recovering compensation — no matter how strong your case is. This guide explains the rules in plain English so you know exactly where you stand.
The Basic Deadline: 3 Years Under Washington Law
Washington State sets a three-year statute of limitations for most medical malpractice claims. This rule is found in RCW 4.16.350. The clock typically starts on the date the medical negligence occurred — not the date you realized something went wrong.
For example, if a surgeon made an error on January 1, 2022, you generally must file your lawsuit by January 1, 2025. If you miss that window, a court will almost certainly dismiss your case.
Because three years can pass quickly — especially when you're recovering from an injury — it's smart to connect with a legal intake specialist early rather than waiting until the deadline is close.
The Discovery Rule: When You Didn't Know Right Away
Sometimes patients don't realize they were harmed by malpractice until months or even years later. Washington recognizes this reality through what's called the discovery rule.
Under RCW 4.16.350, the three-year clock can start from the date you discovered — or reasonably should have discovered — that the injury was caused by negligence, rather than the date the act itself occurred.
However, there is an important outer limit called the statute of repose: Washington law caps medical malpractice claims at eight years from the date of the negligent act, regardless of when you discovered the harm. This is a hard cutoff. Even if you had no way to know about the malpractice, you generally cannot sue after eight years have passed.
Because the interplay between the discovery rule and the statute of repose can be complicated, confirm your specific deadline with a licensed Washington attorney.
Special Rules for Minors and People Under a Legal Disability
Washington has different rules for vulnerable claimants:
- Minors (children under 18): The statute of limitations is generally tolled — meaning paused — until the child turns 18. After that, the standard three-year window typically begins. However, the eight-year statute of repose still applies, so a child harmed very early in life could still face a deadline before turning 18 in some situations. Always verify with an attorney.
- Persons with a legal disability: If the injured person is legally incompetent at the time of the malpractice, the limitations period may be tolled until that disability is removed.
These exceptions are narrow. Do not assume they apply without speaking to a qualified professional.
Pre-Suit Notice Requirement in Washington
Washington is one of several states that requires potential plaintiffs to give advance notice before filing a medical malpractice lawsuit. Under RCW 7.70.100, you must serve written notice of intent to file a claim on every defendant at least 90 days before you actually file suit.
This 90-day notice period is separate from — and in addition to — the three-year statute of limitations. In practice, this means you should treat your effective deadline as roughly 90 days earlier than the three-year mark. If you wait until the last few months to act, you could find yourself unable to comply with both requirements in time.

What Counts as Medical Malpractice in Washington?
Not every bad medical outcome is malpractice. Under Washington law (RCW 7.70.040), a successful claim generally requires proving:
- A duty of care existed between you and the healthcare provider.
- The provider breached the standard of care — meaning they acted in a way a reasonably competent provider would not have.
- That breach directly caused your injury.
- You suffered actual damages — physical, financial, or emotional harm.
Common examples include surgical errors, misdiagnosis, delayed diagnosis, medication errors, birth injuries, and failure to obtain informed consent.
Steps to Take If You Think You Have a Claim
- Document everything. Request copies of all medical records related to the incident.
- Write down your timeline. Note when the treatment occurred, when symptoms appeared, and when you first suspected a problem.
- Avoid social media. Posts about your health or the incident can be used against you.
- Talk to a personal injury attorney. Washington malpractice cases require expert testimony and careful preparation — these are not DIY cases.
- Act quickly. Even if you think you have time, deadlines in malpractice cases sneak up fast.
Frequently Asked Questions
Can I file a medical malpractice claim if a loved one died due to negligence?
Yes. Washington allows wrongful death claims under RCW 4.20.010 and survival actions that carry forward claims the deceased could have brought. These claims have their own nuances, so confirm deadlines and who can file with an attorney.
Does Washington cap medical malpractice damages?
Washington does not currently cap non-economic damages (such as pain and suffering) in medical malpractice cases. A Washington Supreme Court ruling struck down a prior cap as unconstitutional. However, laws can change — verify current rules with your attorney.
What if the negligence happened at a government-run hospital?
If the hospital is a state or local government entity, additional rules apply. You may need to file a formal tort claim notice within a shorter window — sometimes as little as the general three-year period but with specific procedural steps. Government claims can be more complex, so act sooner rather than later.
How do I know if the statute of limitations has already passed for my case?
Calculating your deadline depends on when the negligence occurred, when you discovered it, and whether any tolling exceptions apply. Only a licensed Washington attorney can give you a definitive answer for your specific situation. Use our free intake tool to describe your case and get pointed in the right direction.
Does the three-year clock apply to all healthcare providers?
Generally yes — physicians, surgeons, nurses, dentists, chiropractors, and hospitals are all covered under RCW 7.70. The same statute of limitations framework applies across most licensed healthcare providers in Washington.
Time limits in Washington medical malpractice cases are strict, and the consequences of missing a deadline are severe. The more you understand your rights now, the better position you'll be in to protect them.
