RES PERIT DOMINO. The thing is lost to the owner. This phrase is used to express that when a thing is lost or destroyed, it is lost to the person who was the owner of it at the time. For example, an article is sold; if the seller have perfected the title of the buyer so that it is his, and it be destroyed, it is the buyer's loss; but if, on the contrary, something remains to be done before the title becomes vested in the buyer, then the loss falls on the seller.
