How long can creditors make a claim for unpaid bills?

This might not be a simple question. Your best option is to have a wills and estates lawyer in your area review the entire situation, to get advice that you can rely on.  One place you can look for an attorney is our website, http://attorneypages.com

There are too many variables for me to generalize much, and to some extent this will be a matter of Texas law, where I'm not licensed.  If the estate has followed all the rules exactly as it should, in the situation, that should be the end of things.  If not, it's best to deal with it as soon as possible and make it right -- ultimately, that's almost always the cheapest and easist approach, in the long run.
