The development, which was reported by multiple media outlets on Friday, alleges several issues. They include:

Attorney Alexander Seligson, who handled a refinance on a property owned by Mayweather, is also listed as a defendant in the lawsuit, which was filed in a New York court.

"The conduct alleged in this pleading – including the diversion of settlement proceeds, refinance proceeds, and recurring real estate distributions to accounts controlled by Jona Rechnitz through Frist Apex Ventures – demands a full judicial accounting," Mayweather's attorney, Leo Jacobs, said in a statement, per ESPN. "We look forward to obtaining that accounting and to recovering every dollar to which our client is entitled."

Mayweather is also dealing with a multitude of other legal issues.

On Thursday, he was ordered to pay nearly $1 million in back child support after fathering a baby with a dancer from his Vegas gentlemen’s club. The IRS filed a $7.3 million lien against him in March for unpaid taxes in 2018 and 2023. And he sued former broadcast partner Showtime in February, alleging $340 million in misappropriated funds.

The 49-year-old Hall of Famer is also a defendant across several complaints alleging unpaid tabs for private jet services, luxury apartment rentals, and jewelry.

Mayweather, who earned an estimated $1.15 billion during his career, is planning to come out of retirement to face Manny Pacquiao in a rematch on September 25 in Las Vegas. Mayweather also has a planned exhibition against Greek kickboxer Mike Zambidis on June 27 in Athens, and another against Mike Tyson later this fall.
