Players can not delete a league. But the game will if the league is inactive enough I believe. Each weak X amount of wealth is removed from a league's total. When that total hits zero and no more wealth weekly payment can be taken I think the league is disbanded.
But for you you can quit that league by appointing someone else as chairman and then you quitting the league. You can not leave the league if you are the only person left. If you are the only person left in the league you can make an alt, add it to the league and make it chairman so you can leave.
