A year ago I hired a person as my talent manager for my music career . I sent him 3 of my songs for promotion purposes but then considering that he was no good as a manager I fired him . Now a year later , I see one of MY SONGS on his you tube channel with HIS name on it claiming he wrote and produced the track while I merely performed it which is NOT TRUE . So I want to sue him for copyright infringement . The thing is that my copyright papers are not here yet even though I made the application a year ago . I'm not even provided a diary number for the application , and now I'm scared that if I file a lawsuit against him then I won't have enough grounds to do that since I don't have the copyright papers . Is there any other way by which I can get him to pay up for this disgusting thing he pulled ?
