This Texas Mechanics Lien form is for use in collecting payment for work done. The claimant may make written demand for payment of the claim to an owner authorized
to withhold funds under this subchapter. The demand must give notice to
the owner that all or part of the claim has accrued under Section 53.053
or is past due according to the agreement between the parties. The claimant must send a copy of the demand to the original contractor. The claimant's demand may accompany the original notice of nonpayment or of a past-due claim and may be stamped or written in legible form on the face of the notice. Unless the lien has been secured, the demand may not be made after expiration of the time within which the claimant may secure the lien for the claim. § 53.083.
