The powers of and incidental to leasing, accepting surrenders of leases and management, conferred on trustees for sale whether by this Act or otherwise, may, until sale of the land, be revocably delegated from time to time, by writing, signed by them, to any person of full age (not being merely an annuitant) for the time being beneficially entitled in possession to the net rents and profits of the land during his life or for any less period: and in favour of a lessee such writing shall, unless the contrary appears, be sufficient evidence that the person named therein is a person to whom the powers may be delegated, and the production of such writing shall, unless the contrary appears, be sufficient evidence that the delegation has not been revoked.
Any power so delegated shall be exercised only in the names and on behalf of the trustees delegating the power.
The persons delegating any power under this section shall not, in relation to the exercise or purported exercise of the power, be liable for the acts or defaults of the person to whom the power is delegated, but that person shall, in relation to the exercise of the power by him, be deemed to be in the position and to have the duties and liabilities of a trustee.
Where, at the commencement of this Act, an order made under section seven of the Settled Land Act, 1884, is in force, the person on whom any power is thereby conferred shall, while the order remains in force, exercise such power in the names and on behalf of the trustees for sale in like manner as if the power had been delegated to him under this section.
