TPR – Uniform Child Custody Jurisdiction and Enforcement Act
“Wis. Stat. § 822.23 does not require a court to dismiss a custody action as soon as it discovers that another state had entered a custody order for the child when the action was commenced in this state. It prohibits the court from modifying the custody determination of another state unless the other court has declined jurisdiction,” ¶15.
