Daughter who lived with decedent and cared for her received substantial benefits under a 2006 will and 2014 codicil. Despite medical evidence to the contrary, the court determined that the decedent did not suffer from a weakened intellect in 2006, but did suffer from a weakened intellect when the codicil was executed, so the will was held to be valid but the codicil was not. Kefalos Estate, 11 Fid.Rep.3d 154 (Allegheny O.C. 2020).
