My name is XXXXX XXXXX I'd be happy to answer your questions today. I'm sorry to hear that this happened.
You do have the option of filing suit against your parents for the money. The law prohibits you from forcing the sale of the home in order to pay the debt, but once you get a judgment you could put a lien on the property that would have to be paid before title could be transferred. As a practical matter, that could help you if your parents should pass away before the judgment expires. A judgment in Texas is good for 10 years and can be renewed for another 10.
Another option would be to ask your parents to voluntarily give you a lien on the property. They could sign something agreeing that, in exchange for your not suing them on the debt, they will give you a lien on the mobile home
. That could be recorded and would allow you to get the money before the home could be sold. If you want to go that route, and they agree, it's a good idea to have a local attorney draft it to cover multiple scenarios. They could do that in a will, but wills can always be changed, so there's less protection for you.
