Texas Property Code - PROP § 53.151. Enforcement of Remedies Against Money Due Original Contractor or Subcontractor

(a) A creditor of an original contractor may not collect, enforce a security interest against, garnish, or levy execution on the money due the original contractor or the contractor's surety from the owner, and a creditor of a subcontractor may not collect, enforce a security interest against, garnish, or levy execution on the money due the subcontractor, to the prejudice of the subcontractors, mechanics, laborers, materialmen, or their sureties.

(b) A surety issuing a payment bond or performance bond in connection with the improvements has a priority claim over other creditors of its principal to contract funds to the extent of any loss it suffers or incurs. That priority does not excuse the surety from paying any obligations that it may have under its payment bonds.
