Texas · TREC 39-11Texas Amendment to Contract (TREC 39-11): what it can change
The TREC Amendment to Contract (39-11, effective July 1, 2026) is the form buyer and seller sign to change an executed Texas contract. Its boxes cover the sales price, repairs, the closing date, the closing-cost amounts in ¶12, lender-required repairs, an extension of the option period for an additional option fee, waiving the option, the Buyer Approval date of the financing addendum, and other modifications. Every changed date must be recounted on the deal's timeline.
What each box changes
(1) Sales price
The cash portion, the financing and the new sales price.
(2) Repairs
Additional repairs and treatments the seller completes; ¶7 of the contract governs them.
(3) Closing date
A new date in ¶9.
(4)–(6) Money at closing
The amounts in ¶12 and how lender-required repairs are paid.
(7) Option extension
An additional option fee extends the unrestricted right to terminate to 5:00 p.m. on a new date; the parties choose whether it is credited to the price.
(8) Waive the option
The buyer gives up the unrestricted right to terminate.
(9) Buyer Approval date
A new date for the buyer's notice under the Third Party Financing Addendum.
(10) Other
Other modifications – brokers and agents may not practice law; the form tells the parties to consult an attorney.
