Wyoming Will Contest Deadline

Updated September 7, 2026. Quick answer: In Wyoming, you have 3 months to contest a will that has already been admitted to probate, running from the first publication of the probate notice (not the court’s order date).

How long do you have to contest a will in Wyoming?

“Any action to set aside the Will shall be filed in the Court within three months from the date of the first publication of this notice, or thereafter be forever barred.”

What makes Wyoming different

Wyoming’s trigger is publication of the probate notice rather than the court’s order date, so the real deadline depends on when the personal representative got around to publishing, not on any court-entered date. The controlling authority is Wyo. Stat. § 2-7-201, and the window runs from the first publication of the probate notice (not the court’s order date).

What happens once this deadline passes?

Once the window above closes, Wyoming’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 Wyoming allowed at the original probate hearing does not reopen or extend it.

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 Wyoming probate court file can confirm.
