He has been in an ongoing legal battle with Aydin and Company, a jeweler in Atlanta. According to legal documents, Mase owes them this large sum of money from way back in 2005. Supposedly Mase has been ducking the lawsuit and the jeweler, whenever they make an attempt to serve him with papers. Mase had asked the case to be dismissed, but the jewelers want the $35,000, their attorney fees and 1.5% interest per month.
So far no judge has ruled either way though.
