Thank you.I am a legal assistant for a Lawfirm. I asked one of the attorneys about this and the answer was simple. If the law changes after the signing of a contract or agreement with the HOA, the state law will prevail. That is why most contacts you sign in Texas have a severability clause. Once the law changes, that portion of the contract becomes void and the rest remains in tact.
The short of it is that if passed, this bill will prevent anyone in Texas, HOAs included, from restricting to less than 6 backyard hens.
