New England Sports Ventures are set to complete their takeover of Liverpool after the club's co-owners removed the restraining order blocking any sale.
Tom Hicks and George Gillett accepted defeat in their bid to prevent a sale to New England Sports Ventures (NESV), but say they will pursue £1bn damages.
NESV, the board's choice as Liverpool's new owners, will hope to complete their £300m purchase of the club on Friday.
But Hicks and Gillett will "pursue every legal avenue" to claim damages.
The co-owners had lifted the restraining order blocking the club's sale earlier on Friday, but not so that the current board could complete a deal with NESV.
Hicks was believed to be negotiating the sale of his shares with US hedge fund Mill Financial, who already own Gillett's shares after he defaulted on a £75m loan from RBS in August.
But the Premier League rejected Mill's requests to undergo a fit and proper person test on Thursday, saying it could only negotiate with the Liverpool board.
The board - comprising chairman Martin Broughton, managing director Christian Purslow and commercial director Ian Ayre as well as Hicks and Gillett - had already accepted a bid from NESV by three votes to two for them to become the club's new owners.
NESV, who own the Boston Red Sox baseball team in the United States and are owned by John W Henry, will now gain control over the Anfield outfit.
But Hicks and Gillett, who gave up hope of holding on to Liverpool at a court in Dallas on Friday, say they will sue for at least £1bn for an "extraordinary swindle".
Steve Stodghill, the Texas attorney representing Hicks and Gillett, added: "This outcome not only devalues the club but it also will result in long-term uncertainty for the fans, players and everyone who loves this sport because all legal recourses will be pursued.
"Mr Hicks and Mr Gillett pledged to pay the debt to RBS so that the club could avoid administration that was threatened by RBS. That offer was rejected.
"It is a tragic development that others will claim as a victory. This means it won't be resolved the way it should be resolved.
"My clients worked tirelessly to resolve these issues but RBS would not listen to any reasonable solution and the directors acted selfishly and illegally. Mr Hicks and Mr Gillett wanted to position this club for the future, but others have a different agenda.
"In truth, there is nothing positive from these events for Liverpool Football Club. That is exactly the opposite of what my clients wanted to achieve."
