Here is the SCDSL rule.
Players committing to play for a SCDSL member team will commit to that team for the “season”. The “season” is defined as August 1st through State or National Cup for that player’s team. State/National Cup competition shall be defined as any local, regional or national USYS Competition. Players will not be able to transfer to another SCDSL team unless the DOC’s from both clubs have approved the transfer. Transfers from a SCDSL team to a team participating in another league other than the SCDSL may be contested and denied in accordance to the Cal South transfer rules. Players transferring from a non-SCDSL team to a SCDSL team, may be contested by the outgoing club, in accordance to the Cal South transfer rules. Players may transfer to a team within the same club in accordance to Cal South transfer rules at any time. The SCDSL Transfer Rule is strictly enforced and all member clubs are expected to follow the rule as it is intended.
The transfer rule that the SCDSL adopted is enforceable at the league level. The new Cal South Transfer Rule (effective 8/1/14) now requires DOC approval from both clubs on the release and transfer, no matter what league the player participates in. It also includes an appeal process, through Cal South, if the outgoing DOC refuses the player release. However, for SCDSL purposes, clubs that disregard the SCDSL rule are undermining the spirit of the league, and will be subject to board and Technical Committee review, and potential non-renewal for the following season. Even if an appeal is upheld through Cal South and the player is allowed to release from a SCDSL team, the incoming SCDSL club is expected to obtain the required approval from the outgoing DOC per the SCDSL Transfer Rule. If the outgoing DOC denies the transfer then the incoming club cannot register the player via a transfer.
Specifically, a player release (drop) from any SCDSL team and subsequent signing at any time prior to the end of State/National Cup competition, as defined above, by another SCDSL team, is considered a transfer and will be considered a violation of the SCDSL rule as it is intended.
