152(1)An insured may, in a contract or by a declaration, other than a declaration that is part of a will, filed with the insurer at its head or principal office in Canada during the lifetime of the person whose life is insured, designate a beneficiary irrevocably; and in that event the insured, while the beneficiary is living, may not alter or revoke the designation without the consent of the beneficiary and the insurance money is not subject to the control of the insured or of his creditors and does not form part of his estate.

152(2)Where the insured purports to designate a beneficiary irrevocably in a will or in a declaration that is not filed as provided in subsection (1), the designation has the same effect as if the insured had not purported to make it irrevocable.
