Magic Stick was released on Lil' Kim's 2003 album La Bella Mafia and got to number two in the Billboard Hot 100.
A spokesperson on behalf of 50 Cent said Carlos Evans would be paid as soon as a sample he used had been licensed and payment had gone through.
Carlos Evans maintains that he was promised $7,500 (£3,700) advance plus royalties for producing, engineering and mixing Magic Stick but that he has had nothing apart from an advance from Rotten Apple Records, who are a subsidiary of the Atlanic label.
Carlos Evans is seeking $2m (£1m) damages but there is no comment as yet from Atlantic Records.
