The levying officer shall serve a copy of the court order on the third person at the time the copy of the writ of attachment and the notice of attachment are served on the third person. (b) A court order is not required as a prerequisite to levy on a deposit account or safe-deposit box standing in the name of any of the following: (1) The defendant, whether alone or together with third persons. (2) The defendant’s spouse, whether alone or together with other third persons. An affidavit showing that the person in whose name the account stands is the defendant’s spouse shall be delivered to the financial institution at the time of levy.

A copy of a fictitious business name statement, certified as provided in Section 17926 of the Business and Professions Code, that satisfies these requirements shall be delivered to the financial institution at the time of levy and, if a person other than the defendant is listed in the statement, an affidavit showing that the other person is the defendant’s spouse shall also be delivered to the financial institution at the time of levy.

The levying officer may not require the financial institution to pay the amount levied upon until the expiration of 15 days after service of notice of attachment on the third person.
