that the Release states that the child support obligation was paid in full. Further, the Release provides that under section 157.322 of the family code the lien has been satisfied. Section 157.322 states that a release will be executed when the underlying child support obligation has been paid in full. See Tex. Fam.Code Ann. § 157.322(a). The Release, therefore, on its face, purports to discharge Joseph of the full amount of his arrearages and is a prima facie rebuttal to the AG’s claim that Joseph owed more than $47,000 in arrearages. See Deer Creek Ltd., 792 S.W.2d at 201; Martin, 294 S.W. at 241. Thus, because the Release is valid on its face, the burden shifted to the AG to produce evidence that would result in the Release being set aside. See, e.g., Williams, 789 S.W.2d at 264 (<HOLDING>); see also Tamez v. Sw. Motor Transp., Inc.,
