A deed is a written instrument, which has been signed and delivered, by which one individual, the grantor, conveys title to real property to another individual, the grantee; a conveyance of land, tenements, or hereditaments, from one individual to another. In most parts of the United States, deeds must be submitted to the Recorder of deeds, who acts as a cadastre, to be registered. An unrecorded deed may be valid proof of ownership between the parties, but may have no effect upon third-party claims until disclosed or recorded. A local statute may prescribe a period beyond which unrecorded deeds become void as to third-parties, at least as to intervening acts.
State laws greatly vary with respect to deed law. The laws of some of the states relating to deeds can be found at the following links.
