West Ham settle dispute with Curbishley
Curbishley resigned in September 2009, claiming the sale of Anton Ferdinand and George McCartney breached his contract.
The League's Managers' Arbitration Tribunal had previously upheld his case for wrongful dismissal.
"It has taken many months to conclude this case but I am proud of my record at West Ham which included a win ratio of 40 percent, after initially keeping the club in the Premier League and a 10th place finish in my only full season in charge," Curbishley said in a statement on the LMA website on Wednesday.
"I would like to thank (West Ham's new co-owner) David Sullivan for acting quickly and concluding the settlement.
"With my managerial record intact, I am now looking forward to the future and getting back into football management."
Curbishley, who began his career as a player at West Ham and spent 15 years as manager of Charlton Athletic, has been out of the game since leaving Upton Park after less than two years.
