There's two different things going on and you seem to be on the side of "who did more work"
And that's not anybody's point.. You can do 99% of the work... Guess what? I still want my fukking credit for the 1%... Here's where it gets real funky.. Y0ou can do 99% of the work, but if the contract says we split 50/50 regardless, THAT'S YOUR DUMB ASS FAULT FOR SIGNING THAT CONTRACT.. That doesn't mean that when you feel like it, you get to change shyt up, take shyt, remove me or anything else NOT IN THE CONTRACT
Seems like the Roots, Pharrell signed up to be The Neptunes and split earnings. Chad fades away and the contract don't change fam. You either buy him out, continue to pay him or quit and leave yourself. Just because you navigated a way to fukk him out the deal, don't make it right cause you doing the work. That's LAW... contract law. Which is why he's going to lose the lawsuit with ease
You think Chad faded away and now he's just fukking up his best friends name and rep and begging for scraps he's not owed and did zero work on..... cause reasons?
