An attorney is NOT required. I would encourage you to talk to a higher up at the bank. I have pasted California probate code 13105 below. Note section (b) provides for attorney fees if the bank forces you to get an attorney. You might show that code section to them. Hopefully they will see the light! Good luck.
13105. (a) If the requirements of Sections 13100 to 13104,
inclusive, are satisfied:
(1) The person or persons executing the affidavit or declaration
as successor of the decedent are entitled to have the property
described in the affidavit or declaration paid, delivered, or
transferred to them.
(2) A transfer agent of a security described in the affidavit or
declaration shall change the registered ownership on the books of the
corporation from the decedent to the person or persons executing the
affidavit or declaration as successor of the decedent.
(b) If the holder of the decedent's property refuses to pay,
deliver, or transfer any personal property or evidence thereof to the
successor of the decedent within a reasonable time, the successor
may recover the property or compel its payment, delivery, or transfer
in an action brought for that purpose against the holder of the
property. If an action is brought against the holder under this
section, the court shall award reasonable attorney's fees to the
person or persons bringing the action if the court finds that the
holder of the decedent's property acted unreasonably in refusing to
pay, deliver, or transfer the property to them as required by
subdivision (a).
