Sec. 209. Information to be submitted to court.

(a) Subject to any other law providing for the confidentiality of procedures, addresses, and other identifying information, in a child-custody proceeding, each party, in its first pleading or in an attached affidavit, shall give information, if reasonably ascertainable, under oath as to the child's present address or whereabouts, the places where the child has lived during the last five years, and the names and present addresses of the persons with whom the child has lived during that period. The pleading or affidavit must state whether the party:

(1) has participated, as a party or witness or in any other capacity, in any other proceeding concerning the custody of or visitation with the child and, if so, identify the court, the case number, and the date of the child-custody determination, if any;

(2) knows of any proceeding that could affect the current proceeding, including proceedings for enforcement and proceedings relating to domestic violence, protective orders, termination of parental rights, and adoptions and, if so, identify the court, the case number, and the nature of the proceeding; and

(3) knows the names and addresses of any person not a party to the proceeding who has physical custody of the child or claims rights of legal custody or physical custody of, or visitation with, the child and, if so, the names and addresses of those persons.

(b) If the information required by subsection (a) is not furnished, the court, upon motion of a party or its own motion, may stay the proceeding until the information is furnished.

(c) If the declaration as to any of the items described in subsection (a)(1) through (3) is in the affirmative, the declarant shall give additional information under oath as required by the court. The court may examine the parties under oath as to details of the information furnished and other matters pertinent to the court's jurisdiction and the disposition of the case.

(d) Each party has a continuing duty to inform the court of any proceeding in this or any other state that could affect the current proceeding.

(e) (Blank).

(f) If a party states in the pleading or the affidavit that disclosure of an address would risk abuse or harm to the party or a family member, the address may be omitted from documents filed with the court. A party is not required to include in the pleading or affidavit a domestic violence safe house address or an address changed as a result of a protective order.
