Two or more persons who are entrusted with property for the benefit of one or more others. 2. Unlike joint executors, joint trustees cannot act separately, but must join both in conveyances and receipts, for one cannot sell without the others, or receive more of the consideration money, or be more a trustee than his partner. The trust having been given to the whole, it requires their joint act to do anything under it. They are not responsible for money received by their co-trustees, if the receipt be given for the mere purposes of form. But if receipts be given under circumstances purporting that, the money, though not received by both, was under the control of both, such a receipt shall charge, and the consent that the other shall misapply the money, particularly where he has it in his power to secure it, renders him responsible.
