Notice to any bank, Connecticut credit union or federal credit union of any adverse claim to all or any portion of the balance of a deposit account or share account held within this state and, according to such bank's or credit union's records, for the credit of any person, shall not be effectual to cause such bank or credit union to recognize such adverse claimant unless such adverse claimant also either (1) procures a restraining order, injunction or other appropriate process against such bank or credit union from a court of competent jurisdiction in a cause instituted by such person wherein each person for whose credit the deposit account or share account is held, or such person's executor, administrator, receiver, custodian, legal representative or heir, is made a party and is served with summons, or (2) executes to such bank or credit union, in a form and with sureties acceptable to it, a bond indemnifying such bank or credit union from any and all liability, loss, damage, costs and expenses for and on account of the payment of such adverse claim or the dishonor of the check or other order of the person for whose credit the deposit account or share account, according to the records of such bank or credit union, is held; provided this section shall not apply in any instance where the person for whose credit the deposit account or share account is held, according to the records of such bank or credit union, is a fiduciary for such adverse claimant, and the facts constituting such relationship, and the facts showing reasonable cause of belief on the part of such claimant that such fiduciary is about to misappropriate all or any portion of the balance of such deposit account or share account, are made to appear by affidavit of such claimant. An adverse claimant means one who is not a named owner, joint owner or co-owner of the deposit account or share account according to the bank's or credit union's records.
