The recorded deed is the starting point for seeing whose names are on the Buffalo property. Marriage, separation, or living at the house does not by itself answer which signatures a sale needs.
New York automatic orders can restrict a spouse from transferring property while a divorce case is underway. A written agreement or a case-specific court order may also affect what can happen with the house. Have a New York divorce attorney explain the papers that apply to you; the title company checks the deed, applicable orders, and required signatures for closing. You can talk with us while those questions are being reviewed.
