Unless the applicable deposit contract or share contract provides that the account is nontransferable, and except to the extent that such deposit contract or share contract otherwise limits such right, the interest of any named owner in any savings account or share account established or maintained at any Connecticut bank or Connecticut credit union, except a savings or share account subject to negotiable orders of withdrawal, or in any time account established or maintained at such bank or credit union, without regard to whether any such account is held in the names of one or more persons, may be pledged by such named owner, without the consent of any other named owner thereof by delivery to the pledgee of (1) the passbook, if any, evidencing such account, and (2) an order to the Connecticut bank or Connecticut credit union to transfer such pledged account to the pledgee; but no such pledge shall be effective against any person other than the named owners, their executors or administrators, or their receivers or custodians, unless an actual transfer of such account to the pledgee has been made upon the books of such bank or credit union, or a copy of the order for such transfer has been filed with the bank or credit union. Any pledgee which makes a loan based on the pledge of a savings account, time account or share account as provided in this section shall have a lien against such account until all sums due under the loan have been repaid. The Connecticut bank or Connecticut credit union with which such savings account, time account or share account is established or maintained may be a pledgee under this section. This section does not apply to a negotiable certificate of deposit subject to the terms of article 9 of title 42a.
