Perry Rogers of Alliance Sports Management Co. represented Andre Agassi during his years of greatness and claims to have concurrently represented his wife, Steffi Graf. Rogers says that he is owed more than $50k in commissions from Graf.
The interesting point is that with endorsement deals, agents are notoriously paid directly from the marketers, take their cut, and then send the rest of the money to the client (which is different from how an agent is paid from negotiating a contract with a team for a baseball, football, or basketball player).
How then is Rogers still owed $50k?
Apparently this is how:
"[The lawsuit] says Graf agreed to pay Rogers’ company 15 percent of all business ventures once an investment account had reached $20 million. Graf stopped paying Rogers after the October split with Agassi."
For fifty thousand bucks, I think this bad boy gets settled before any more news leaks out.
