The British cook fell out with his wife's family in 2010 when he fired his father-in-law Chris Hutcheson as chief executive of his restaurant business.
Hutcheson subsequently filed a lawsuit against Ramsay, while the TV star hit back by filing his own legal papers against several of his wife Tana's relatives.
Ramsay accused Hutcheson of hacking into his personal and company files, withdrawing millions of dollars from the firm and using the money to reportedly fund a double life with an alleged mistress.
The legal battle has now formally ended after both sides agreed on an out-of-court settlement, although details of the deal have not been released.
Ramsay's representatives at Freud Communications tell Britain's Daily Mail in a statement, "Gordon Ramsay and Gordon Ramsay Holdings have reached a settlement with Chris Hutcheson and other members of the Hutcheson family.
"The terms of the settlement are confidential but we can confirm that Chris Hutcheson is no longer a director or shareholder of Gordon Ramsay Holdings and all civil litigation and employment tribunal claims brought by each of the two parties and other family members have been withdrawn."
