A Football League tribunal has ruled Oldham Athletic must pay Bury an initial fee of £30,000 for Dale Stephens.
The midfielder moved to Boundary Park in the summer despite the two clubs failing to thrash out a fee for the out-of-contract 20-year-old.
Stephens has failed to break into the League One table toppers' first team to date, other than in the Carling Cup, but Bury will be entitled to further payments when he meets a set number of games.
Athletic must pay the Shakers further £10,000 instalments should the player reach 15, 30, 45 and 60 senior games - meaning a possible further £40,000.
A lump sum of £25,000 will be payable should John Sheridan's side achieve promotion to the Championship within the next two years, providing Stephens has played in at least half of the fixtures, while Bury will also net a 20 per cent cut of any future transfer fee should the player be sold on.
Oldham chief executive Alan Hardy declared himself content with the tribunal's verdict.
"We are relatively happy considering the initial demands we received from Bury," he told the club's official website.
"I suppose out of the two parties, they will be the more disappointed."
