Cal. Fin. Code § 1613
Notwithstanding any other provision of law, any bank and any trust company holding securities in a fiduciary capacity or while engaged in a trust business, or while acting in any capacity under a court or private trust, or while acting in that capacity with one or more persons as cofiduciary or cofiduciaries, unless the instrument creating the trust contains a provision to the contrary, is authorized to deposit or arrange for the deposit with a federal reserve bank of any such securities the principal and interest of which the United States or any department, agency, or instrumentality thereof has agreed to pay, or has guaranteed payment, to be credited to one or more accounts on the books of the federal reserve bank in the name of the bank or trust company, to be designated fiduciary or safekeeping accounts, to which accounts other similar securities may be credited. Any bank or trust company that deposits or arranges for the deposit of securities pursuant to this section shall maintain records that at all times show the ownership of the securities deposited. A bank or trust company depositing securities pursuant to this section shall be subject to such rules and regulations as in the case of state-chartered institutions, the commissioner and, in the case of national banking associations, the Comptroller of the Currency, may from time to time issue. Ownership of, and other interests in, the securities credited to such account may be transferred by entries on the books of the federal reserve bank without physical delivery of any securities. A bank or trust company acting as custodian for a fiduciary shall, on demand by the fiduciary, certify in writing to the fiduciary the securities deposited by the bank or trust company pursuant to this section for the account of the fiduciary. A fiduciary shall, on demand by any party to its accounting, certify in writing to that party the securities deposited for its account as a fiduciary pursuant to this section. This section shall apply to all fiduciaries and custodians for fiduciaries, acting on the effective date of this section or who thereafter may act regardless of the state of the instrument or court order by which they are appointed.
