Wyo. Stat. § 1-1-117

(a) In any action, whether in tort, contract or otherwise, in which the plaintiff seeks damages, a party may, in lieu of answering or otherwise pleading, file an affidavit certifying that he was not directly or indirectly involved in the occurrence or occurrences alleged in the action. If an affidavit is filed, the court shall order the dismissal of the claim against the certifying party, except as provided for in subsection (b) of this section. The affidavit shall be filed within the time required for filing an answer, if no answer is filed; and, in any event, at least twenty (20) days prior to trial. Any order of dismissal based on the affidavit shall not be entered within ten (10) days after the affidavit is filed.

(b) Any party may oppose the dismissal or move to vacate the order of dismissal and reinstate the certifying party, provided he can show that the certifying party was directly or indirectly involved in the occurrence or occurrences alleged in the action. After the filing of an affidavit under this section, the party opposing the dismissal may have discovery with respect to the involvement or noninvolvement of the party filing the affidavit, provided the discovery is completed within sixty (60) days of the filing of the affidavit.
