(a) A petitioner seeking to enforce a child custody determination must verify the petition and attach copies of certified copies of all orders or notice sought to be enforced and of any order confirming registration if such child custody determination has been registered.

(b) 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 must be enforced under this chapter and, if so, identify the court, the case number and the nature of the proceeding; (3) whether any proceeding has been commenced that could affect the current proceeding, including proceedings relating to family violence, protective orders, termination of parental rights and adoptions and, if so, identify the court, the case number, and the nature of the proceeding; (4) the present physical address of the child and the respondent, if known; (5) whether relief in addition to the immediate physical custody of the child and attorneys’ fees are sought, including a request for assistance from law enforcement officials, and, if so, the relief sought; and (6) if the child custody determination has been registered and confirmed under § 46b-115w, the date and place of registration.

(c) Upon the filing of a petition, the court shall issue an order directing the respondent to appear in person with or without the child at a hearing, the time and place of which shall be specified, and may enter any order necessary to ensure the safety of the parties and the child. The order shall advise the respondent that at the hearing, the court will order that the petitioner take immediate physical custody of the child and the payment of fees, costs and expenses under § 46b-115ee, and any other relief that the court may deem appropriate, unless the respondent appears and establishes that: (1) The child custody determination has not been registered and confirmed pursuant to § 46b-115w and (A) the court issuing the order for which enforcement is sought did not have jurisdiction under § 46b-115k, 46b-115l or 46b-115m or a provision substantially similar to said sections; (B) the child custody determination for which enforcement is sought has been vacated, stayed or modified by a court having jurisdiction to do so under sections 46b-115k to 46b-115t, inclusive; or (C) the respondent was entitled to notice, but notice of the proceedings before the court that issued the order for which enforcement is sought was not given in accordance with § 46b-115g or in a manner reasonably calculated to provide actual notice; or (2) the child custody determination for which enforcement is sought was registered and confirmed pursuant to § 46b-115w, but has been vacated, stayed or modified by a court of a state having jurisdiction to do so under § 46b-115k, 46b-115l or 46b-115m or a provision substantially similar to said sections. The hearing must be held on the next business day after service of the order unless otherwise ordered for good cause shown. The court may extend the date of the hearing at the request of the petitioner.
