The decedent’s former wife and her sister had lent large amounts of money to the decedent for his support, and there were written communications sufficient to show an oral contract for enforceable claims against the decedent which were not barred by the four year statute of limitations because the statute did not begin to run until a demand for payment was made. In re: Estate of Fred Gitterman, Deceased, 1647 EDA 2023 (Pa. Super. 4/3/2024) (non-precedential).
