You had a closing attorney. That is the person to ask.
Why didn't you know the car was there?
I purchased a house in 1971 from an estate. The heir lived in CA and wanted the house sold. It was completely furnished. I sold most of the contents to antique dealers. There was a
1949 Desoto in the gargage. Because I had inspected the property, I knew all of this in advance and my closing attorney made sure I had title to "all properties not removed." I gave the car to one of my brothers who refurbished it and held it until 1989 when he sold it. My share of the proceeds was a case of Chevis Regal and a case of Drambuie.Dick
