The decedent’s granddaughter, who was not a beneficiary under the contested will and was not an intestate heir because her mother (the decedent’s daughter) was still living, had standing to challenge the will offered for probate by her mother because her mother had conveyed some of the decedent’s property to her after the decedent’s death and before the contested will was offered for probate, and the granddaughter’s rights in the property would be affected whether the mother was disinherited by the contested will. It was not an abuse of discretion for the Orphans’ Court to find that the contested will was a forgery based on telephonic testimony from a publisher of electronic forms that the contested will appeared to be a form that was not published until after the decedent’s death. Other issues raised by the appellants were waived because the appellants failed to obtain a transcript of the relevant hearing. In re: Estate of Marjorie Virginia Renninger, Deceased, 588 WDA 2023 (Pa. Super. 3/29/2024) (non-precedential).
