In Texas, real estate contracts must be in writing to be enforced (Statute of Frauds). A verbal "okay" means nothing.
Here is everything you need to know about extending TREC contract deadlines without voiding your deal or opening yourself up to a lawsuit. In the context of the Texas Real Estate Commission (TREC), an "extension" refers to the Third Party Financing Amendment (TREC Form 50) or the general Amendment to Contract (TREC Form 39) .
These forms are not just polite requests. They are legally binding documents that alter the "Time is of the Essence" clause in the One to Four Family Residential Contract (TREC 20-16).
