The Lollipop star filed a $51 million (£39 million) lawsuit against his Cash Money Records boss in early 2015 accusing his former mentor of withholding money he was allegedly owed for his album Tha Carter V, which remains unreleased.

Wayne's lawyers filed further documents earlier this month (Sep16) asking to look at Williams' accounting to see how he allegedly spent the $70 million (£54 million) they were supposed to split from a $100 million (£77 million) advance given by executives at parent company Universal Music Group.

Williams claimed most of the funds went on royalty payments, marketing and recording expenses and Wayne's team requested access to his accounts to find receipts for these, as they claim the 20,000 pages of financial documents Williams representatives submitted to court don't include that information.

A judge has now sided with Lil Wayne's team and is forcing Birdman to open up his accounts, according to TMZ.com. Birdman's Cash Money accounting team reportedly haven't been keeping their books or receipts in order for two years, but the judge remained firm and gave them 30 days to find the records and send them to Wayne's lawyers.
