Things are getting ugly between Rascal Flatts and their former management firm, Turner Nichols and Associates. According to Courthouse News, the band's ex-managers are asking for a 15 percent cut of the band's earnings on their current tour, despite the fact that the parties ended their relationship in February and even issued a statement saying that the split was not acrimonious.

Well, what a difference a few months makes! Turner Nichols is arguing that their firm negotiated the tour and is therefore owed. They also contend that they are owed compensation since they were crucial in building the band’s career. Part of the suit says that Turner Nichols supported the band "when the defendants were struggling and unknown singers, initially financing their careers out of the plaintiff's own funds. The plaintiff has guided the defendants' careers to success as internationally famed singers and recording artists, as multi-platinum record sellers, and as tremendously successful touring artists who have achieved astounding financial success, earning hundreds of millions of dollars."

All that legal-ese aside, the company says it is responsible for elevating Rascal Flatts to country superstardom and is therefore entitled to a payday for a tour that it negotiated while still under contract. The tour ends in June 2013, so Turner Nichols wants to be paid through that date. The firm claims that the band ceased payment after their February split.

Beyond tour revenue, the agency also demands commissions for TV appearances and DVDs that it negotiated.

Rascal Flatts issued a terse but totally professional statement on the matter, saying, "We are disappointed they have chosen to file as we had hoped to address these issues privately. However, we hope that this can be resolved amicably."
