Yes, at the instant of death the account becomes the property of the named POD Beneficairies. Any signature authority of the person existing before death would terminate as theaccount now belongs to multiple parties. What you need to do is present a death certificate, the bank will then divide the account accordingly and issue a cashier's check for your portion. If you are concerned, be sure that the POD person with check writing authority did not write checks after death.
Best of luck.
