Wyo. Stat. § 1-22-106: When petition to be filed; order for hearing.

A petition to adopt a child shall be filed upon the entry of the child in the adoptive home or as soon thereafter as is reasonably convenient. When a petition is filed and presented to the judge, he shall set the petition for hearing. Any person whose consent to adoption is required by W.S. 1-22-109 and whose consent has not been filed shall be ordered to appear on the day set and show cause why the petition to adopt should not be granted and a decree of adoption entered.
