There is not one signing answer for every house. Start with the recorded deed: it shows the ownership names and how title is held. A divorce order or other recorded document may also affect the sale. The title company reviews the deed and closing documents to confirm the signatures and paperwork needed for this closing.
If a court order addresses the house, share it with the title company rather than guessing what it changes. An Alabama family-law attorney can explain how an order applies to your situation. You can talk with us while those details are being checked.
Alabama Code §30-2-51 is a state-law reference; the Alabama Judicial System provides statewide court resources. Neither determines who must sign for a particular house; the deed, any order, and the closing review matter for that property.
