The answer is yes. It should NOT happen but it could. If you think there is a pending lawsuit (guardianship is a lawsuit) then go to the courthouse and look at the public records. Most are computerized these days and you would look up the adults names.The only notice you receive is someone handing you a piece of paper that tells you there is a pending lawsuit. That is all that is required in Texas. If a process server or constable tried to serve you and left their card, then you know that there is a pending lawsuit.You need to file a legal document called an Answer in order to be involved in the lawsuit.Of course, I tell people to hire a lawyer to represent them to make sure everything is done properly.
