Raising estate duty by sale, mortgage or terminable charge
31.—(1)  A person authorised or required to pay the estate duty in respect of any property shall, for the purpose of paying the duty, or raising the amount of the duty when already paid, have power, whether the property is or is not vested in him, to raise the amount of that duty and any interest and expenses properly paid or incurred by him in respect thereof, by the sale or mortgage of or a terminable charge on that property or any part thereof.
Payment by limited owner
(2)  A person having a limited interest in any property, who pays the estate duty in respect of that property, shall be entitled to the like charge, as if the estate duty in respect of that property had been raised by means of a mortgage to him.
Payment of duty out of “capital money”
(3)  Any money arising from the sale of property comprised in a settlement or held upon trust to lay out upon the trusts of a settlement may be expended in paying any estate duty in respect of property comprised in the settlement and held upon the same trusts.
