PONTIAC (AP) — A Michigan judge agreed to allow a handwriting expert to examine wills discovered in couch cushions after Aretha Franklin’s death.

During a hearing Tuesday, Oakland County Probate Judge Jennifer Callaghan also placed administration of Franklin’s estate under court supervision. That means the court will have a role in major decisions about her estate, including the sale of property. A handwritten 2014 document shows Franklin apparently wanted her son, Kecalf Franklin, to serve as the representative of her estate, which might be worth millions. Erich Speckin was hired by the son to verify his mother’s handwriting.
