Satisfied terms, whether created out of freehold or leasehold land to cease

(1) Where the purposes of a term of years created or limited at any time out of freehold land become satisfied, either before or after the commencement of this Act (whether or not that term either by express declaration or by construction of law becomes attendant upon the freehold reversion), it shall merge in the reversion expectant thereon and shall cease accordingly. (2) Where the purposes of a term of years created or limited at any time out of leasehold land become satisfied after the commencement of this Act, that term shall merge in the reversion expectant thereon and shall cease accordingly. 19 (3) Where the purposes are satisfied only as respects part of the land comprised in a term, this section shall have effect as if a separate term had been created in regard to that part of the land.
