Start with the recorded deed: it shows whose names are recorded as owners. A divorce agreement, judgment, or court order about the house may also affect whether or how it can be sold. New York automatic orders can restrict property transfers while a divorce case is underway.
The title company checks the deed and relevant closing documents, then confirms which signatures are needed for this sale. A New York family-law attorney can explain what an agreement or order means for your situation. You can discuss the house with us while those papers are being gathered or reviewed.
