USAV National rules state that once a player has registered (paid dues to USAV RVA) they may only represent that one club for the entire season. Also, the rule is that once a junior player has participated in a JOVC qualifying event, he/she may not participate in another JOVC qualifying or championship event with a different club unless a waiver is granted by the Arbitrator and the regions involved.
If any of the 3 conditions above have been met the player/parents are obligated to the club for the entire USAV season.
