California Code, Financial Code - FIN § 1554

In this section, “subject national banking association” means a national banking association that (a) maintains its main office or a branch office in this state, (b) is authorized to transact a trust business, and (c) has complied with the requirements of Article 3 (commencing with Section 1570) of this chapter and of all other laws of this state relating to the deposit of securities for the protection of court and private trusts. A subject national banking association may engage in and conduct a trust business and may be appointed by any court to act in any fiduciary capacity in which a trust company is authorized to act. All acts provided in this code to be performed by the commissioner, the State Treasurer, or other public officials for or in respect to the deposit of securities by trust companies, shall be performed for subject national banking associations equally with trust companies. Every subject national banking association shall be permitted to use the word “trust” in its corporate name and to advertise its authority to engage in and conduct a trust business and to advertise for and solicit trust business in this state, notwithstanding any contrary provision in this division or in any other law. The commissioner shall have access to reports of examination made by the Comptroller of the Currency insofar as they relate to the trust department of a subject national banking association. For purposes of Article 3 (commencing with Section 1570), the principal place of business of a national banking association that maintains its main office in another state of the United States and maintains a California branch office shall be deemed to be situated in the city where the California branch office is located or, if the national banking association maintains California branch offices in two or more cities, in the city with the largest population.
