(a) The court in which a suit has been filed after a child has been taken into possession without a court order by a governmental entity shall hold an initial hearing on or before the first business day after the date the child is taken into possession. The court shall render orders that are necessary to protect the physical health and safety of the child. If the court is unavailable for a hearing on the first business day, then, and only in that event, the hearing shall be held no later than the first business day after the court becomes available, provided that the hearing is held no later than the third business day after the child is taken into possession.
(b) The initial hearing may be ex parte and proof may be by sworn petition or affidavit if a full adversary hearing is not practicable.

(c) If the initial hearing is not held within the time required, the child shall be returned to the parent, managing conservator, possessory conservator, guardian, caretaker, or custodian who is presently entitled to possession of the child.
(d) For the purpose of determining under Subsection (a) the first business day after the date the child is taken into possession, the child is considered to have been taken into possession by the Department of Family and Protective Services on the expiration of the five-day period permitted under § 262.007(c) or 262.110(b), as appropriate.
