Wyo. Stat. § 20-7-102 (2026)

rights.

     (a) With notice or reasonable efforts to provide notice to
the noncustodial parent, a person may bring an original action
against any person having custody of the child to establish
reasonable visitation rights to the child if the person bringing
the original action has been the primary caregiver for the child
for a period of not less than six (6) months within the previous
eighteen (18) months. If the court finds, after a hearing, that
visitation would be in the best interest of the child and that
the rights of the child's parents are not substantially
impaired, the court shall grant reasonable visitation rights to
the primary caregiver. In any action under this section for
which the court appoints a guardian ad litem, the person
bringing the original action under this section shall be
responsible for all fees and expenses associated with the
appointment.
     (b) No action to establish visitation rights under
subsection (a) of this section may be brought by a person
related to the child by blood or by a person acting as primary
caregiver for the child prior to the adoption of the minor child
when neither adopting parent is related by blood to the child.

     (c) In any action or proceeding in which visitation rights
have been granted to a primary caregiver under this section, the
court may for good cause upon petition of the person having
custody or who is the guardian of the child, revoke or amend the
visitation rights granted to the primary caregiver.
