Bona Fide Purchaser

commonly called BFP in legal and banking circles; a person who has purchased an asset for stated value, innocent of any fact which would cast doubt on the right of the seller to have sold it in good faith. This is vital if the true owner shows up to claim title, since the BFP will be able to keep the asset, and the real owner will have to look to the fraudulent seller for 
recompense.
