Is is possible for someone to place a lien on personal property? My father is insisting that I owe him $20,000 on the sale of my home. I had purchased it from him 5 years ago and he had given me a large discount on the sale price of the home. Now that I'm selling it, he insists he is entitled to this amount. My mother is dead set against it, she was involved with my purchase as well. Can he put a lien on the property? There is no legal papers with any of this on it.
