Mr. Sterling's attorney had said late Thursday—before Ms. Sterling announced the deal—that Mr. Sterling hadn't yet decided what he will do.
Ms. Sterling has been running a process to sell the team and said early Friday that she had signed a binding contract for the sale. She and Mr. Sterling each owns half of the team through a trust they share, though he is the owner as recognized by the NBA.
Ms. Sterling, in announcing the deal, said she was acting under "her authority as the sole trustee of the Sterling Family Trust." Ms. Sterling believes that she has the authority to declare Mr. Sterling mentally incapacitated and to sell the team without his consent under provisions lined out in the trust they share, people familiar with her thinking said.
It remains unclear what authority Ms. Sterling has or whether the NBA would agree to a sale without Mr. Sterling's approval
