Definitions of deed

a legal document that is written in a particular form and signed, usually concerning the ownership of property or the granting of legal rights. In some jurisdictions, particular agreements must be in the form of a deed. This is especially true when property or a right is transferred from one party to another, with nothing being given in return.
