Sale and Purchase Agreements/Contracts

[Oscar Freiman]

As a real estate investor, when buying and selling a property, in my case in the state of Texas, is it better to utilize the contract that has been promulgated by Texas Real Estate Commission (TREC)? or one drafted by a state licensed attorney? 

Basically, I would like to make sure:

1) I do not want to get in trouble/uprotected because some required clause is missing.

2) I do not want to get in trouble/uprotected because there is a clause that does not need to be in the contract/agreement.

I'll appreciate your experienced feedback.

Thank you.
