Clear title

[Denise Plonis]

I'm new here. I need to find out what needs to be done to sell my mother's house.

My dad died in 1984 without a will in Bell County Texas. The house was in both their names. 1/2 the house went to my mom and 1/2 to the kids. Me, my brother and my sister signed a quit claim deed to allow my mom to live in the house. The 'kink' is that my dad had a daughter from a previous marriage. We believe he signed adoption papers, but cannot find any record. Supposedly, someone at the time of my father's death put ads in the papers of the last known city where the mother and/or daughter lived. We have never been able to find any information about the daughter. Looking at the property info from the Bell County Website, it lists my mom as having 100% ownership and in the deed history it is listed as Warranty Deed as of 10/15/1984.

Does this mean that my mother has a clear title and can legally sell the house?
