Section 3

No assignment made after the passing of this Act of a policy of life assurance shall confer on the assignee therein named, his executors, administrators, or assigns, any right to sue for the amount of such policy, or the moneys assured or secured thereby, until a written notice of the date and purport of such assignment has been given to the assurance company liable under such policy at its principal place of business for the time being; and the date on which such notice was received shall regulate the priority of all claims under any assignment; and a payment bona fide made in respect of any policy by any assurance company before the date on which such notice was received shall be as valid against the assignee giving such notice as if this Act had not been passed.
