An Anglo-French word, meaning "that person," which appears in the legal phrases cestui que trust, use, or vie. It is usually pronounced as "cetty." Cestui que trust means literally "the person for whose benefit the trust" is created. The cestui que trust is the person entitled to the equitable, as opposed to the legal, estate. Thus, if land be granted unto, and to the use of A. in trust for B., B. is cestui que trust, and A. trustee. The term, principally owing to its cumbersomeness, is being gradually superseded in modern law by that of "beneficiary." Cestui que use (sometimes cestui a que use) means "the person for whose benefit a use" is created (see Trust). Cestui que vie is "the person for whose life" lands are held by another (see Remainder).
