Feuds have dominated every stage of the stuttering discussions over the past years, with arguments over drug testing and financial splits.
Set to be the richest fight in boxing history, the purse is expected to start at $250m (£160m) - with Mayweather guaranteed a minimum $150m (£96m) and Pacquiao's share at least $100m (£64m).
With Mayweather understood to have commanded the 60-40 split of the purse, the fight will occur – with an autumn rematch clause believed to have been written into the deal by Mayweather.

The 37-year-old is understood to have been the dominant figure throughout negotiations – right up to getting his wish to announce the fight, which he did via Shots.com - a social media site in which he has a stake in.
He posted the contract along with the comment: 'What the world has been waiting for has arrived. Mayweather vs. Pacquiao on May 2, 2015, is a done deal. I promised the fans we would get this done, and we did. We will make history on May 2nd. Don't miss it! This is the signed contract from both fighters.'
The fight will be a joint pay-per-view event shown on Showtime, the channel Mayweather is contracted to, and HBO who have the deal to show Pacquiao's fights.
According to reports, every room in the MGM Grand sold out within three minutes of the fight being announced.
