Balfour v. Seitz‪.‬

Sometime prior to 1930 decedent opened in his own name a savings account in the Mars National Bank of Mars, Pa. Approximately twenty to twenty-two years later - between October 1950 and September 26, 1952 - the name of Letitia Seitz, one of decedents nine children, was added to this account which was then styled "John L. Balfour or Letitia Seitz." Neither a signature card, withdrawal agreement, nor a survival agreement was ever signed by the parties. The bank did not require any written agreement in connection with its savings accounts.
