6. (1) A policy of insurance effected by any married man on his own life, and expressed on the face of it to be for the benefit of his wife, or of his wife and children, or any of them, shall ensure and be deemed to be a trust for the benefit of his wife, or of his wife and children, or any of them, according to the interest so expressed, and shall not, so long as any object of the trust remains, be subject to the control of the husband, or to his creditors, or form part of his estate. When the sum secured by the policy becomes payable, it shall, unless special trustees are duly appointed to receive and hold the same, be paid to the Official Trustee of Bangladesh in which the office at which the insurance was effected is situate, and shall be received and held by him upon the trusts expressed in the policy, or such of them as are then existing. And in reference to such sum he shall stand in the same position in all respects as if he had been duly appointed trustee thereof by ²[the Supreme Court under the Official Trustees Act, 1913]. Nothing herein contained shall operate to destroy or impede the right of any creditor to be paid out of the proceeds of any policy of assurance which may have been effected with intent to defraud creditors. (2) Notwithstanding anything contained in section 2, the provisions of sub-section (1) shall apply in the case of any policy of insurance such as is referred to therein which is effected by any Hindu, ³[Muslim], Sikh or Jaina, in Bangladesh after the first day of April, 1923: Provided that nothing herein contained shall affect any right or liability which has accrued or been incurred under any decree of a competent Court passed before the first day of April, 1923.
