11. Trustee to execute trust.- The trustee is bound to fulfil the purpose of the trust, and to obey the directions of the author of the trust given at the time of its creation, except as modified by the consent of all the beneficiaries being competent to contract. Where the beneficiary is incompetent to contract, his consent may, for the purposes of this section, be given by a principal Civil Court of original jurisdiction. Nothing in this section shall be deemed to require a trustee to obey any direction when to do so would be impracticable, illegal or manifestly injurious to the beneficiaries. Explanation.-- Unless a contrary intention be expressed, the purpose of a trust for the payment of debts shall be deemed to be (a) to pay only the debts of the author of the trust existing and recoverable at the date of the instrument of trust, or, when such instrument is a will, at the date of his death, and (b) in the case of debts not bearing interest, to make such payment without interest.
