I'm not a Texas attorney, but my research suggests that Texas law recognizes both joint tenancy with right of survivorship, and a special form of that called tenancy by the entireties for married couples.  You would have to have an attorney in your area look at the deed to be certain, but I think it's most likely that the home was owned by the entireties, and that means it belongs solely to the widow.A short consultation with a lawyer, with a copy of the deed, will confirm this, and the attorney can also write a letter, if necessary, to put a stop to the children's claims.  One place to find a lawyer in your area is our website, http://attorneypages.com
