Cal. Fin. Code § 1586
With regard to any participation certificates heretofore issued by any trust company, secured by a trust deed or mortgage, the full legal title in the deed or mortgage and debt (referred to in this section as "security") shall be held by the trust company issuing the certificates as trustee of an express trust, with all powers necessary to extend, renew, enforce, collect, and liquidate the same, acquire title to the property covered thereby either through foreclosure or by voluntary conveyance; manage, lease, sell (either for cash or upon deferred payments), exchange, or otherwise realize upon the security or property and distribute the net proceeds thereof. All sums so realized shall, as and when received by such trustee, after payment of its compensation and all costs, charges, and expenses, including brokers' commissions and advances for taxes and assessments, incurred or made in connection with the protection, administration, and liquidation of the security or property, be distributed to the trusts or persons who are beneficiaries of the trust, as their interests may appear therein. The rights and interests therein of any such beneficiary failing to contribute on demand its or his pro rata of sums advanced, expended, or required by the trust company in the protection, administration, or liquidation of the trust shall be subject to a lien for all sums, with legal interest thereon advanced, expended, or required for any of such purposes by the trustee or by any other beneficiary of the trust.
The trust in such security or property shall continue in the trust company so long as any of the certificates are outstanding, irrespective of any distribution of the certificates from the trust in which the same are held.
The purpose of this section is to define and clarify the rights and obligations of trust companies and of all persons and trusts interested in participation certificates issued under any authority of law.
