We learned last night that Lil Wayne was making good on his threat to sue longtime business partner Birdman. He officially filed suit for $51 million, and the Fader obtained scans of the lawsuit that detail just why and how it came to this.

In 2012, Wayne (known in court as Dwayne Michael Carter) and Cash Money Records optioned for four more albums albums together plus a duet album at $10 million an album. Things went bad just a few months ago, when Cash Money stopped paying Wayne’s Young Money LLC a quarterly allowance of $200,000.

Cash Money is also guilty, the suit claims, of:

“(i) failing to pay Carter Eight Million Dollars ($8,000,000.00) for delivery of “Tha Carter V”;
(ii) failing to properly account and pay royalties to Carter for monies earned by Carter’s recordings;
(iii) prohibiting Carter from auditing the books and records of Cash Money; and
(iv) knowingly failing to register the copyright of the Carter recordings for the album “I Am Not a Human Being II” in both Cash Money’s and Carter’s names.”

Sounds like Wayne was kept away from the books for a long time. Read through the lawsuit below for particulars.
