Minn. Stat. § 518.165
Subd. 1. Permissive appointment of guardian ad litem.
In all proceedings for child custody or for dissolution or legal separation where custody or parenting time with a minor child is in issue, the court may appoint a guardian ad litem from a panel established by the court to represent the interests of the child. The guardian ad litem shall advise the court with respect to custody, support, and parenting time.
Subd. 2. Required appointment of guardian ad litem.
In all proceedings for child custody or for marriage dissolution or legal separation in which custody or parenting time with a minor child is an issue, if the court has reason to believe that the minor child is a victim of domestic child abuse or neglect, as those terms are defined in sections 260C.007 and 626.556, respectively, the court shall appoint a guardian ad litem. The guardian ad litem shall represent the interests of the child and advise the court with respect to custody, support, and parenting time. If the child is represented by a guardian ad litem in any other pending proceeding, the court may appoint that guardian to represent the child in the custody or parenting time proceeding. No guardian ad litem need be appointed if the alleged domestic child abuse or neglect is before the court on a juvenile dependency and neglect petition. Nothing in this subdivision requires the court to appoint a guardian ad litem in any proceeding for child custody, marriage dissolution, or legal separation in which an allegation of domestic child abuse or neglect has not been made.
