Bournemouth chairman Peter Phillips says the board of directors may quit if the sale of Dean Court falls through.
The Cherries are in talks with a property company who want to buy the ground and lease it back to the club.
The plan has apparently not gone down well with members of the supporters' trust, Community Mutual, who could have the casting vote on the sale.
Phillips told the Echo: "If the CM vote against the position of everybody on the board becomes untenable."
He added: "There is no dispute within the board that this deal is right for the club.
"If the CM decide they are against refinancing then they will have to take responsibility for their decision. They have a great deal of power now, and with power comes responsibility."
