According to a statement released by the organization, “Pursuant to long-established succession plans, Mr. Ford's controlling interest in the Lions passes to [his widow] Mrs. Martha Ford. She and her four children will continue to be involved in the ownership of the franchise, as they have during Mr. Ford's tenure.”
Ford's son, William Clay Ford Jr., will remain as the team's vice chairman. As the Detroit Free Press notes, he's held that role since 1995.
Regarding Martha Ford, mlive.com writes, "She is not expected to be heavily involved in the family's daily football operation, though her inheritance of the Lions ensures the team stays in the family."
