Fin. Code, § 6661

Notice to an association or federal association of an adverse claim to a savings account of, or to personal property held for the account of, any person shall be disregarded, and the association or federal association, notwithstanding the notice, shall honor withdrawal applications and shall pay withdrawals and interest to the person or persons to whose credit the account stands or shall deliver the property to or upon the order of the person for whose account the property is held, without any liability on the part of the association or federal association; subject, however, to the exceptions provided in subdivisions (a) and (b):

(a) If an adverse claimant delivers to the association or federal association at the office at which the account is carried or the property held an affidavit of the claimant stating that of the claimant’s own knowledge the person to whose credit the deposit stands or for whose account the property is held is a fiduciary for the adverse claimant and that the claimant has reason to believe the fiduciary is about to misappropriate the account or the property, and stating the facts upon which the claim of fiduciary relationship and the belief are founded, the association or federal association shall refuse to pay withdrawals or interest on the account and shall refuse to deliver the property for a period of not more than three court days (including the day of delivery) from the date that the association or federal association received the adverse claimant’s affidavit, without liability on its part and without liability for the sufficiency or truth of the facts alleged in the affidavit.

(b) If at any time, either before, after, or in the absence of the filing of an affidavit by the adverse claimant, the adverse claimant procures and serves upon the association or federal association at the office at which the account is carried or the property held a restraining order, injunction, or other appropriate order against the association or federal association from a court of competent jurisdiction in an action in which the adverse claimant and all persons in whose names the account stands or for whose account the property is held are the parties, the association or federal association shall comply with the order or injunction, without liability on its part.

(c) The provisions of this section shall be applicable even though the name of the person appearing on the books to whose credit the account stands or for whose account the property is held is modified by a qualifying or descriptive term such as “agent,” “trustee,” or other word or phrase indicating that the person may hold the account or property in a fiduciary capacity.

(d) Nothing in the California Multiple-Party Accounts Law contained in Part 2 (commencing with Section 5100) of Division 5 of the Probate Code limits the applicability of this section.
