It's in the TREC forms in zip forms "Notice to Prospective Buyer." An important part of the contract as it relates to this notice is that the "Buyer" get this notice BEFORE the contract is EXECUTED. If you fail to get this signed before execution of the contract, then under Section 6 E 3 the buyer could terminate the contract at any time up to closing. You can refer to Chapter 49 of the Texas Water Code for further information as the contract suggests.
Getting it from the title company in advance works but after execution...not so much.
