A quitclaim deed is a term used in property law to describe a document by which a person (the "grantor") disclaims any interest the grantor may have in a piece of real property and passes that claim to another person (the grantee). A quitclaim deed neither warrants nor professes that the grantor's claim is actually valid. By comparison, a grant deed (or in some U.S. States, a warranty deed), which is normally used for real estate sales, contains certain warranties that vary from state to state. Quitclaim deeds are sometimes used for transfers between family members, gifts, placing personal property into a business entity, or to eliminate clouds on title, or in other special or unusual circumstances.
