Updated September 7, 2026. Quick answer: In Oregon, you have 4 months to contest a will that has already been admitted to probate, running from delivery or mailing of the required post-probate notice to that person, or publication of notice, whichever applies and is later.
How long do you have to contest a will in Oregon?
| Deadline to contest an admitted will | 4 months |

“An action described in subsection (1) of this section must be commenced before the later of: (a) Four months after the date of delivery or mailing of the information described in ORS 113.145 if that information was required to be delivered or mailed to the person on whose behalf the action is filed; or (b) Four months after the date of publication of notice to interested persons if the person on whose behalf the action is filed was not required to be named in the petition for probate as an interested person.”

What makes Oregon different
Oregon’s deadline is person-specific rather than a single fixed date for the whole estate; each interested party’s own 4-month clock starts from when that person was actually notified, so different contestants can have different deadlines for the same will. The controlling authority is ORS 113.075, and the window runs from delivery or mailing of the required post-probate notice to that person, or publication of notice, whichever applies and is later.
What happens once this deadline passes?
Once the window above closes, Oregon’s probate of the will generally becomes final and binding on everyone who had the chance to object, subject only to the tolling or discovery exceptions described above; a separate objection Oregon allowed at the original probate hearing does not reopen or extend it.

Every statute or rule quoted on this Oregon page was read directly from the state’s own legislature/court/code site this session, or, where that site blocked automated access, from a reputable legal-citation mirror quoting the same official text with its official citation (disclosed below). General information, not legal advice; whether a specific contest is still timely can turn on facts (exactly when notice was given, how the will was probated, whether a disability applies) that only your own Oregon probate court file can confirm.
