Power to several trustees of whom at least one is competent to contract

Power to several trustees of whom at least one is competent to contract.—When any authority to deal with the trust-property is given to several trustees and concurrently is given to all of them, if one of them disclaims or dies, the authority may be exercised by the continuing trustees, unless from the terms of the instrument of trust it is apparent that the authority is to be exercised by a number in excess of the number of the remaining trustees.
