California Code, Insurance Code - INS § 10498.5

If a holder of a certificate of exemption receives or maintains funds for any purpose other than administering and providing the benefits that make it subject to this article, it shall segregate and maintain separately all funds received by it for the purpose of administering and providing such benefits.

When so segregated and maintained separately such benefit funds are not subject to enforcement of a money judgment or other process by or on behalf of creditors of the holder of a certificate of exemption, except that such funds are subject to enforcement of a claim for benefits.
