Texas Local Government Code - LOC GOV'T § 399.014. Lien

(a) A contractual assessment under this chapter and any interest or penalties on the assessment:

(a-1) After the notice of a contractual assessment is recorded as provided under Section 399.013, the lien may not be contested on the basis that the improvement is not a qualified improvement or the project is not a qualified project.

(b) The lien runs with the land, and that portion of the assessment under the assessment contract that has not yet become due is not eliminated by foreclosure of a property tax lien.

(c) The assessment lien may be enforced by the local government in the same manner that a property tax lien against real property may be enforced by the local government to the extent the enforcement is consistent with Section 50, Article XVI, Texas Constitution.

(d) Delinquent installments of the assessments incur interest and penalties in the same manner as delinquent property taxes.

(e) A local government may recover costs and expenses, including attorney's fees, in a suit to collect a delinquent installment of an assessment in the same manner as in a suit to collect a delinquent property tax.
