CESTUI QUE TRUST, A barbarous phrase, to signify the beneficiary of an
estate held in trust. He for whose benefit another person is enfeoffed or
seised of land or tenements, or is possessed of personal property. The
cestui que trust is entitled to receive the rents and profits of the land;
he may direct such conveyances, consistent with the trust, deed or will, as
he shall choose, and the trustee (q.v.) is bound to execute them: he may
defend his title in the name of the trustee. 1 Cruise, Dig. tit. 12, c. 4,
