Amending a Texas Contract: The TREC 39-11

Executed contracts change by written amendment — checked boxes, filled blanks, both signatures.

What it covers

The rule that matters

An amendment binds only when both parties execute it. Until then, the original deadlines keep running — extend the option period BEFORE it expires, not after.

Educational only — not legal advice. TREC forms are for use by trained license holders; talk to your broker or an attorney about your specific transaction.
