Boxing Hall of Fame member and former heavy weight champion Michael Tyson and his wife, Lakiha Tyson, have filed suit against a financial advisor and his company for $5 million in damages, according to papers filed in Los Angeles Superior Court.

The Tysons are suing SFX Financial Advisory Management Enterprises Inc., a financial planning firm with a reputation for handling entertainment and sports figures. They have also named Live Nation Entertainment Inc., of which SFX is a subsidiary, and Brian Ourand, the person at SFX who handled their account.

The suit, filed February 20, charges Ourand allegedly embezzled $300,000 from the Tysons when he was supposed to be handling the Tyson’s bankruptcy filing. It further says SFX removed Ourand from the account and assigned a new person without immediately informing the Tysons of the change or of the embezzlement. SFX has not replied to a request for a comment on the suit.

The decade-old bankruptcy filing capped the amount Tyson could earn. Money above the cap was to be turned over to the IRS. The suit claims SFX/Live Nation also cost the Tysons money by not concluding the bankruptcy filing, by forcing them to pay other extensive legal fees and by preventing Tyson from taking advantage of lucrative business opportunities.

Tyson had a cameo appearance in the movie The Hangover and has a one-man autobiographical show, Mike Tyson: Undisputed Truth.

According to the lawsuit, Ourand has never been prosecuted and is now working in Florida for another financial firm. The relationship between SFX/Live Nation and the Tysons began in 2005 and the Tysons became close to Ourand, according to the suit, inviting him to their wedding and giving him the authority to write checks.

The suit, which was filed in Los Angeles because that is where Live Nation has its offices, seeks damages for breach of fiduciary duty, fraud through intentional misrepresentation, and unjust enrichment, among other complaints.
