Summary

Louis Brandeis Security Sav Bank v. State of California…

The contract of deposit does not give the banks a tontine right to retain the money in the event that it is not called for by the depositor. It gives the bank merely the right to use the depositor's money until called for by him or some other person duly authorized. If the deposit is turned over to the state in obedience to a valid law, the obligation of the bank to the depositor is discharged.

Louis Brandeis Security Sav Bank v. State of California…

If a bank account has not been added to or drawn upon by the depositor for more than 20 years, and no one claiming the money has, within that period, filed with the bank any notice showing his present residence, and the president or managing officer of the bank does not know that the depositor is alive, then the bank shall, upon entry of a judgment establishing these facts, deposit with the state treasurer the amount of the deposit and accumulations. The suit cannot be begun until after the expiration of the 20 years.
