According to the suit, Mathew held a secret auction in Houston over Superbowl Weekend, during which he sold various items of Destiny's Child and Beyoncé's memorabilia.
However, he was not able to keep the sale a secret from his former lawyers!
The team caught wind of the auction, and sent a letter to Mathew, demanding that he use the coins he earned to pay what he allegedly owes them --- $50,000.
However, months later, they claim that he still hasn't paid up, and now they have filed a suit to get their money back.
The $50,000 sum was allegedly an amount owed in relation to a venue dispute settlement from April 2016.
Mathew was not immediately available for comment.

UPDATE: A rep for Mathew Knowles told OK!, "This is a lie without any foundation in fact. No such auction occurred nor was ever planned or scheduled. Indeed, Mr. Knowles never participated in nor engaged anyone to hold any type of auction to sell or auction off such items."
