Lil Wayne is having a rough time just before 2015 ends. Ahead of his Dedication Tour next year, Wayne is facing yet another legal battle, and this time the lawyer defending him against Birdman and Cash Money is allegedly suing him for unpaid fees worth $375, 239.

Michael Kramer, Wayne's former lawyer, sued the rapper on Monday, Dec. 21, in the Manhattan Federal Court. According to XXL Mag, Tunechi agreed a payment of $20,000 initial retainer and monthly bills in 2013. However, according to court papers filed, Wayne wasn't able to pay the lawyer's fees until October 2015. In September, Kramer's firm dropped the "6 Foot 7 Foot" singer as their client for failure to pay the accumulated unpaid bills.

As per the lawsuit, Kramer claimed that he tried several times to resolve the case harmoniously, but the 33-year-old Louisiana-born rapper failed to cooperate. Meanwhile, it's been a tough year for Wayne as he's been facing a legal dispute with Cash Money and Birdman. The 33-year-old hip hop recording artist filed a $51 million lawsuit against CM. Based on Wayne's claims, CM owes him $10 million for the unreleased album, Tha Carter V and other unsettled projects, MTV reports.

As for Wayne's mentor, Birdman, he still calls the former his son, "With my son Wayne, I feel like everything we did, and how we built this here...I gave him a $100-plus million contract, $67 million up front, the biggest contract in hip-hop to me," Birdman said in an interview in July. "And it didn't take an organization to do this - I did this for my son and that meant the world to me that I was able to do that. And what's going on now, I don't really know how it's gon' turn out."

It was not the first time that Wayne was sued by his own lawyers. Back in October, law firm Garbett, Allen and Roza filed a lawsuit against the "How To Love" rapper for nonpayment of legal fees amounting to $80,000. Wayne was represented by the firm against the company that leases private jets, Signature Group.  In the end, Wayne was liable to pay the company a total of $2 million.
