Robert Reese filed the document Tuesday in Dauphin County Orphans Court. In another filing Thursday, he printed a letter from the Hershey Trust Co., the bank that manages the charity's money, saying he had been fired as trust president.
Reese also accuses the trust of misspending millions and violating securities regulations.
The Hershey Trust oversees more than $7 billion in assets. Reese is a former top executive at the candy maker and his grandfather started Reese's candy company.
The trust's letter of termination accused Reese of violating securities laws.
