Washington Revised Code Title 48. Insurance § 48.32.100. Nonduplication of recovery

(1) Any person having a claim against his or her insurer under any provision in his or her insurance policy which is also a covered claim shall be required to exhaust first any right under that policy. Any amount payable on a covered claim under this chapter shall be reduced by the amount of a recovery under the claimant's insurance policy.

(2) Any person having a claim that may be recovered under more than one insurance guaranty association or its equivalent shall seek recovery first from the association of the place of residence of the insured except that if it is a first party claim for damage to property with a permanent location, from the association of the location of the property, and if it is a workers' compensation claim or a longshore and harbor workers' compensation act claim, from the association of the permanent residence of the claimant. Any recovery under this chapter shall be reduced by the amount of the recovery from any other insurance guaranty association or its equivalent.
