What is the Medical Malpractice Statute of Limitations in Washington?

In Washington, you have 3 years to file a civil lawsuit for medical malpractice. This deadline is set by Washington state law and is strictly enforced by courts.

Medical malpractice claims arise when a healthcare provider's negligence causes injury or death. Most states use a 'discovery rule' — meaning the clock starts when you discovered (or reasonably should have discovered) the injury, not necessarily when the act occurred.

Common examples of medical malpractice claims:

  • Surgical errors
  • Misdiagnosis or delayed diagnosis
  • Medication errors
  • Birth injuries
  • Anesthesia errors
  • Failure to treat

Why This Deadline Matters

Medical malpractice has some of the shortest time limits of any claim type. Many states impose an absolute 'statute of repose' that bars claims even if you didn't discover the injury until later. Act quickly.

The statute of limitations is a hard legal deadline. Once it passes:

  • Your lawsuit will be permanently dismissed by the court
  • The defendant only needs to raise the deadline as a defense — the merits of your case don't matter
  • There is almost no way to revive a time-barred claim
  • Even the strongest evidence cannot save a case filed too late

When Does the Clock Start in Washington?

For most medical malpractice claims in Washington, the clock starts on the date of the incident or injury. However, there are important exceptions:

  • Discovery rule: The clock may start when you discovered (or should have discovered) the injury, not the date it occurred.
  • Minor victims: If the injured party was under 18, the clock typically doesn't start until they turn 18.
  • Legal incapacity: If the plaintiff was mentally incapacitated, the clock may be paused (tolled).
  • Defendant absent from state: Time the defendant spends outside Washington may not count toward the deadline.
  • Fraudulent concealment: If the defendant actively hid the cause of action, the clock may be extended.

These exceptions are applied narrowly by courts. Do not assume an exception applies without consulting an attorney.
