Club licensing regulations
Starting this season, every team in the Liga Super Malaysia must have a FAM Club Licence to play in the league, or else they are relegated. To obtain a FAM Club Licence, teams must be financially healthy and meet certain standards of conduct as organisations. As part of privation effort for the league, all clubs compete in Liga Super Malaysia and Liga Premier Malaysia will be required to obtained FAM Club Licence.

As in other national leagues, there are significant benefits to being in the top division: Despite several reminders from FAM from the beginning of 2015, however there are few teams failed to get the approval for both AFC and FAM club licenses from First Instance Body (FIB).
