Qualification process
The qualification process is divided into four regions, the Asian Zone, the American Zone, the European Zone and the Australasian Zone. Teams in their respective zone will compete in a knockout format. Teams will compete for two days, with two singles and doubles played on the first day and three singles and two doubles played on the next day.
