Maverick City Music co-founder Chandler Moore has filed a federal lawsuit accusing the Grammy-winning worship collective CEO Norman Gyamfi of stealing royalties via secretive deals and forged contracts.

The lawsuit was filed just days before Moore announced that he was leaving Maverick City Music to pursue solo work and described the decision as “bittersweet.”

The civil complaint, filed Oct. 1 in U.S. District Court in Atlanta and obtained by Billboard, alleges that CEO Norman Gyamfi, who once managed Moore, misused his position to take ownership stakes, commissions and publishing rights without Moore’s knowledge or consent.
