The Constitutional Lien: a Texas Original Contractor's Secret Weapon

May 18, 2026 · 5 min read

Most contractors know about the statutory mechanic's lien in Chapter 53. Fewer know Texas has a second one — written directly into the state constitution — that can protect an original contractor even when the statutory paperwork slips.

What it is

Article XVI, Section 37 of the Texas Constitution grants a lien to “mechanics, artisans and materialmen” for the value of their labor and materials. Courts have long treated it as self-executing for a contractor who dealt directly with the owner — meaning it can exist without the same notice-and-filing steps the statutory lien requires.

Its biggest strength
It can survive when a statutory lien fails on a technicality — a missed notice, a late affidavit — as long as you had a direct contract with the owner.

Its real limits

  • Direct contract only.It protects the original contractor — the party who contracted with the owner. Subs and suppliers generally can't rely on it.
  • Third parties may not be bound.Because there's no public filing requirement, a later buyer or lender without notice may take free of it. Recording a statutory lien is what puts the world on notice.
  • Homestead complications remain.Constitutional status doesn't erase the special homestead contract rules.

How to think about it

Treat the constitutional lien as a backstop, not a plan. Do the statutory process correctly — file the affidavit, hit the deadlines — so your lien is recorded and enforceable against everyone. The constitutional lien is the safety net if a technicality knocks out the statutory one, not a reason to skip the paperwork.
