Texas Family Code - FAM § 156.006. Temporary Orders

(a) Except as provided by Subsection (b), the court may render a temporary order in a suit for modification.

(b) While a suit for modification is pending, the court may not render a temporary order that has the effect of creating a designation, or changing the designation, of the person who has the exclusive right to designate the primary residence of the child, or the effect of creating a geographic area, or changing or eliminating the geographic area, within which a conservator must maintain the child's primary residence, under the final order unless the temporary order is in the best interest of the child and:

(b-1) A person who files a motion for a temporary order authorized by Subsection (b)(1) shall execute and attach to the motion an affidavit on the person's personal knowledge or the person's belief based on representations made to the person by a person with personal knowledge that contains facts that support the allegation that the child's present circumstances would significantly impair the child's physical health or emotional development.  The court shall deny the relief sought and decline to schedule a hearing on the motion unless the court determines, on the basis of the affidavit, that facts adequate to support the allegation are stated in the affidavit.  If the court determines that the facts stated are adequate to support the allegation, the court shall set a time and place for the hearing.

(c) Subsection (b)(2) does not apply to a conservator who has the exclusive right to designate the primary residence of the child and who has temporarily relinquished the primary care and possession of the child to another person during the conservator's military deployment, military mobilization, or temporary military duty, as those terms are defined by Section 153.701.
