(a) If a request for a de novo hearing before the referring court is not timely filed or the right to a de novo hearing before the referring court is waived, the proposed order or judgment of the associate judge, other than a proposed order or judgment providing for enforcement by contempt or the immediate incarceration of a party, shall become the order or judgment of the referring court by operation of law without ratification by the referring court.
(b) An associate judge’s proposed order or judgment providing for enforcement by contempt or the immediate incarceration of a party becomes an order of the referring court only if:
(1) the referring court signs an order adopting the associate judge’s proposed order or judgment; and
(2) the order or judgment meets the requirements of § 157.166.

(c) Except as provided by Subsection (b), a proposed order or judgment of the associate judge is in full force and effect and is enforceable as an order or judgment of the referring court pending a de novo hearing before the referring court.
