When you are considering selling your house and your reach that inevitable struggle with the Sellers' Disclosure Notice required by Texas law, just remember this:
YOU CAN NEVER DISCLOSE TOO MUCH!!!!!!!!!!!
The Texas Property Code requires you to disclose certain specific things about your house. When you sit down to fill that form out, if you even question whether you should or shouldn't write something down, you probably should.
The whole reason my practice continues is because people want to take shortcuts and sell the house without full disclosure. Sometimes, the realtors intervene and advise clients that the issue does not have to be disclosed. (If that happens to you, have the realtor put that down in writing to you and if they won't, you should get a new realtor...)
You can never be sued because you disclosed too much. But you will get sued if you don't disclose enough and it is or becomes a problem.
So the rule of thumb to follow is this:
DISCLOSE AND EXPLAIN
It may slow down your sales activity, and it may change the value of the house, but in reality, if the problem is dramatic or economically substantial, you are going to have to pay the piper later on anyway.
Full and truthful disclosure is an absolute defense to any future claims.
