Quitclaim, a word often used in deeds, and usually in connection with words of grant and conveyance, when the grantor or seller intends to convey to the grantee or buyer all the right, title, interest, and estate of the grantor, but without any warranty whatever, whether of title, quantity, or anything else. Sometimes a deed purports to be a deed of "grant and quitclaim," when the grantor adds to the words of grant and conveyance words of limited warranty: as, for instance, warranty against himself and all persons claiming by, from, through, or under him. Even this limited warranty, and still more a general warranty, would estop the grantor from ousting the grantee by any better title, not coming through the grantee, which was outstanding at the time, and which the grantor might acquire subsequently. But if the deed were one of grant and quitclaim only, without any warranty, the grantor might then assert such a title. For example, A sells and conveys to B, by grant and quitclaim only, for a full price, an estate to which it turns out A has no title. But A subsequently acquires title to it by inheritance from the true owner.

A may now recover the estate from B; but not if he granted with warranty, because if he then took the estate by his better title, B would turn round upon him on the warranty and get the estate back again. Quitclaim is also used in receipts, usually with such words as release and discharge, when it is intended to signify that the party giving the receipt or release agrees never to make any claim against the other party for any existing demand.
