lease and release.Hist. A method of transferring seisin without livery, whereby the owner and the transferee would enter into a lease for a term of years, to take effect only when the transferee entered the property, whereupon the owner would release all interest in the property to the transferee by written instrument. • Once the transferee owned both the term and the freehold interest, the two interests would merge to form one estate in fee simple. This lease-and-release procedure was fully acceptable to the courts, on the theory that livery of seisin to one already occupying the land was unnecessary.
