Start with the recorded deed, but do not assume it answers every divorce-sale question. Texas law generally presumes property possessed by either spouse during marriage or when the marriage ends is community property — part of the marital estate. A spouse claiming a house is separate property has to prove that by clear and convincing evidence.
The deed, how the house was acquired, and any divorce agreement, temporary order, or final decree can affect who may sign and what must happen before a sale. A temporary order may limit what either spouse can do with property while the case is pending; a final decree can divide the marital estate. A title company reviews the deed and closing documents to confirm the signatures needed for this sale. A Texas family-law attorney can explain what a particular order means for you.
