Washington Revised Code Title 48. Insurance § 48.18.440. Spouse's rights in life insurance policy

(1) Every life insurance policy heretofore or hereafter made payable to or for the benefit of the spouse of the insured, and every life insurance policy heretofore or hereafter assigned, transferred, or in any way made payable to a spouse or to a trustee for the benefit of a spouse, regardless of how such assignment or transfer is procured, shall, unless contrary to the terms of the policy, inure to the separate use and benefit of such spouse: PROVIDED, That the beneficial interest of a spouse in a policy upon the life of a child of the spouses, however such interest is created, shall be deemed to be a community interest and not a separate interest, unless expressly otherwise provided by the policy.

(2) In any life insurance policy heretofore or hereafter issued upon the life of a spouse the designation heretofore or hereafter made by such spouse of a beneficiary in accordance with the terms of the policy, shall create a presumption that such beneficiary was so designated with the consent of the other spouse, but only as to any beneficiary who is the child, parent, brother, or sister of either of the spouses. The insurer may in good faith rely upon the representations made by the insured as to the relationship to him or her of any such beneficiary.
