Oregon Deadlines for Related Claims

When the Clock Starts

In Oregon, the limitations period for medical malpractice claims generally begins on the date the injury is first discovered or in the exercise of reasonable care should have been discovered. Oregon recognizes a discovery rule for this claim type: The 2-year clock runs from discovery of the injury, but an absolute 5-year statute of repose from the date of treatment bars all claims (subject only to a fraud/concealment exception giving 2 years from discovery of the fraud).

Exceptions That Can Extend the Deadline

Oregon requires no certificate/affidavit of merit to file, but the 5-year statute of repose in ORS 12.110(4) applies notwithstanding the minor-disability tolling of ORS 12.160.

What to Do Before the Deadline Runs

  1. Pin down your accrual date — the day the clock started — and calendar the deadline conservatively.
  2. Preserve evidence now: photos, records, witness contacts, bills. Evidence decays faster than deadlines.
  3. Send preservation/notice letters where required (especially for Oregon government defendants).
  4. If the deadline is inside 6 months, treat it as urgent — filing suit is the only reliable way to stop the clock.

Frequently Asked Questions

How long do I have to file a medical malpractice claim in Oregon?

You have 2 years from the date the injury is first discovered or in the exercise of reasonable care should have been discovered, under ORS 12.110(4).

Can I still sue after 2 years in Oregon?

Usually no — courts dismiss claims filed after the statute of limitations expires. Narrow exceptions (the discovery rule, tolling for minors, fraudulent concealment) can extend the deadline; whether one applies depends on your facts.

Does the discovery rule apply to medical malpractice claims in Oregon?

Yes. The 2-year clock runs from discovery of the injury, but an absolute 5-year statute of repose from the date of treatment bars all claims (subject only to a fraud/concealment exception giving 2 years from discovery of the fraud).

What if the victim was a minor?

Oregon generally pauses ("tolls") the deadline while the injured person is under 18, giving them time to file after reaching adulthood. Special limits can still apply, so check the statute.

Is the deadline different for claims against the government?

Claims against a public body (e.g., a public hospital) under the Oregon Tort Claims Act require written notice within 180 days of injury (2 years for wrongful death), ORS 30.275.
