Cal. Ins. Code § 1026.1
Where a claim arising out of a policy of insurance has been filed by a third party and approved by the liquidator and such claim has subsequently been paid or satisfied, either wholly or in part, by the transfer of anything of value, either voluntarily or by process, from the insured of the person in liquidation to such third party, then upon the filing with the liquidator of proof of the making and value of such transfer, to the extent and in the manner required by the liquidator, the insured shall be subrogated to the rights of the third party claimant to the extent that the claim has been satisfied and discharged, but the rights of the insured shall not exceed the face value of such claim and if the insured has theretofore filed a claim covering the same subject matter, he is entitled to only one recovery.
