All teams are able to be promoted to
Liga MX 2020–2021 season. The relegated team of the Clausura 2020 Liga MX season will remain in Liga MX if it pays
MXN$120 million to remain the 20th team of the league.
MXN$60 million will go to the Ascenso MX team that would naturally be promoted and
MXN$60 million would go to new projects determined by the Liga MX assembly. If the arrangement is declined, the 19 teams of Liga MX are responsible for
MXN$120 million, the right to be the 20th team of Liga MX will be acceded to the Liga MX assembly. The vacant position in Liga MX could then be occupied by a certified Ascenso MX team or an external sport project. If the position remains open, Liga MX reserves all rights to do as it sees appropriate for the 2020–21 Liga MX season. The first ranked team will qualify for semi-finals and teams ranked second through sixth will qualify for the quarter-finals. •
