Wyo. Stat. § 2-7-709: Actions pending against decedent at time of death.

Any action, including any counterclaim in any pending action, pending against the decedent at the time of his death that survives shall be filed as a claim within the time provided in W.S. 2-7-703 by filing with the clerk in duplicate a certified copy of the order of the court in which the action is pending substituting the personal representative for the decedent, together with a certified copy of any pleading asserting contentions against the decedent. Any judgment thereafter rendered in the pending action shall be subject to the provisions of W.S. 2-7-719. If no claim is filed as provided in this section, any judgment rendered in the pending action, if sought to be enforced, shall be deemed to be a claim not timely filed under W.S. 2-7-703.
