Bouvier's Law Dictionary, Revised 6th Ed (1856)
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. See Risk.
