Section 9--304. Law Governing Perfection and Priority of Security Interests in Deposit Accounts

(a) Law of bank's jurisdiction governs. The  local  law  of  a  bank's
  jurisdiction   governs   perfection,   the   effect   of  perfection  or
  nonperfection, and the priority of a  security  interest  in  a  deposit
  account maintained with that bank.
    (b) Bank's  jurisdiction.  The  following  rules  determine  a  bank's
  jurisdiction for purposes of this part:
         (1) If an agreement between the bank and the debtor governing the
             deposit  account  expressly  provides   that   a   particular
             jurisdiction  is the bank's jurisdiction for purposes of this
             part, this article, or this chapter, that jurisdiction is the
             bank's jurisdiction.
         (2) If paragraph (1) does not apply and an agreement between  the
             bank and its customer governing the deposit account expressly
             provides  that  the  agreement  is  governed  by the law of a
             particular jurisdiction,  that  jurisdiction  is  the  bank's
             jurisdiction.
         (3) If  neither  paragraph  (1)  nor paragraph (2) applies and an
             agreement between the bank and  its  customer  governing  the
             deposit  account  expressly provides that the deposit account
             is maintained at an office in a particular jurisdiction, that
             jurisdiction is the bank's jurisdiction.
         (4) If  none  of  the  preceding  paragraphs  apply,  the  bank's
             jurisdiction   is   the  jurisdiction  in  which  the  office
             identified in an account statement as the office serving  the
             customer's account is located.
         (5) If  none  of  the  preceding  paragraphs  apply,  the  bank's
             jurisdiction is the jurisdiction in which the chief executive
             office of the bank is located.
