Section 157.316 - Perfection of Child Support Lien(a) Except as provided by Subsection (b), a child support lien is perfected when an abstract of judgment for past due child support or a child support lien notice is filed or delivered as provided by Section 157.314.(b) If a lien established under this subchapter attaches to a motor vehicle, the lien must be perfected in the manner provided by Chapter 501, Transportation Code, and the court or Title IV-D agency that rendered the order of child support shall include in the order a requirement that the obligor surrender to the court or Title IV-D agency evidence of the legal ownership of the motor vehicle against which the lien may attach. A lien against a motor vehicle under this subchapter is not perfected until the obligor's title to the vehicle has been surrendered to the court or Title IV-D agency and the Texas Department of Motor Vehicles has issued a subsequent title that discloses on its face the fact that the vehicle is subject to a child support lien under this subchapter.Amended By Acts 2009, 81st Leg., R.S., Ch. 933, Sec. 3C.01, eff. 9/1/2009.Amended By Acts 2001, 77th Leg., ch. 1023, Sec. 24, eff. 9/1/2001.Amended by Acts 1997, 75th Leg., ch. 420, Sec. 5, eff. 9/1/1997Amended By Acts 1997, 75th Leg., ch. 911, Sec. 23, eff. 9/1/1997Added by Acts 1995, 74th Leg., ch. 20, Sec. 1, eff. 4/20/1995.
