Adams' son, Michael, filed a lawsuit Monday in Fresno County Superior Court to keep the board from selling his father's prints, including "Moon and Half Dome" and "Clearing Storm."
Museum officials are selecting auction houses to sell what they can of the Met's collection to pay off its creditors. The museum closed in January because of financial troubles.
Michael Adams is requesting an injunction to stop the auction, which he says would violate a donation agreement made years ago. His lawyer, Melody Hawkins, declined to comment Thursday.
A bankruptcy attorney for the museum says they are trying to work out a solution with Adams.
