The recorded deed is a starting point for seeing whose names appear in the property records. A divorce decree or another court order may also address the house. The deed alone may not answer every signing question, so do not assume that a name on it or a change in marital status by itself settles who can sign for this sale.
The title company reviews the recorded ownership and the documents for the closing, then confirms which signatures it needs. A Texas family-law attorney can explain what a divorce decree or other order means for your situation. You can talk with us about the house while that review is happening.
The official Texas Family Code, Chapter 7, covers court orders dividing property in a divorce. It is a state-law starting point; the deed and any order for a particular house still need to be reviewed by the right professionals.
