Tex. Family Code § 157.3171

(a) An obligor who believes that a child support lien has attached to real property of the obligor that is the obligor's homestead, as defined by Section 41.002, Property Code, may file an affidavit to release the lien against the homestead in the same manner that a judgment debtor may file an affidavit under Section 52.0012, Property Code, to release a judgment lien against a homestead.

(b) Except as provided by Subsection (c), the obligor must comply with all requirements imposed by Section 52.0012, Property Code. For purposes of complying with that section, the obligor is considered to be a judgment debtor under that section and the claimant under the child support lien is considered to be a judgment creditor under that section.

(c) For purposes of Section 52.0012(d), Property Code, and the requirements of the certificate of mailing prescribed by Section 52.0012(g), Property Code, the obligor is required only to send the letter and affidavit described in Section 52.0012(g) to the claimant under the child support lien at the claimant's last known address.

(d) The claimant under the child support lien may dispute the obligor's affidavit by filing a contradicting affidavit in the manner provided by Section 52.0012(e), Property Code.

(e) Subject to Subsection (f), an affidavit filed by an obligor under this section has the same effect with respect to a child support lien as an affidavit filed under Section 52.0012, Property Code, has with respect to a judgment lien.

(f) If the claimant files a contradicting affidavit as described by Subsection (d), the issue of whether the real property is subject to the lien must be resolved in an action brought for that purpose in the district court of the county in which the real property is located and the lien was filed.
