A petition for enforcement of a child custody determination shall state: (1) Whether the court that issued the determination identified the jurisdictional basis it relied upon in exercising jurisdiction and, if so, what the basis was;(2) Whether the determination for which enforcement is sought has been vacated, stayed or modified by a court whose decision shall be enforced under sections 452.700 to 452.930 or federal law and, if so, identify the court, case number of the proceeding and action taken;(3) Whether any proceeding has been commenced that could affect the current proceeding, including proceedings relating to domestic violence, protective orders, termination of parental rights and adoptions, and, if so, identify the court, and the case number and nature of the proceeding;(4) The present physical address of the child and respondent, if known; and(5) Whether relief in addition to the immediate physical custody of the child and attorney's fees is sought, including a request for assistance from law enforcement officials and, if so, the relief sought.3.
