No group life insurance policy, nor its proceeds, shall be liable to attachment, garnishment, or other process, or to be seized, taken, appropriated, or applied by any legal or equitable process or operation of law, to pay any debt or liability of any person insured under the policy, or his beneficiary, or any other person who has a right under the policy, either before or after payment. If the proceeds of a group life insurance policy are not made payable to a named beneficiary, the proceeds shall not constitute a part of the insured person’s estate for the payment of his debts.
