socdad: What I think chico and CHT are saying, it's their money/their kids and they should have freedom to move around as needed, and that the "SCYSA" 30 day window is not needed, and is unreasonable, if the releasing club refuses to sign the form.
Having seen the situation a few times, letting the player go mid year is probably better for the current team than having him/her bide their time through the spring season (IMO this applies to kids looking for higher competition as well as disgruntled families). That said, if the transfer were to cause a team to fold due to lack of players, then I would hope the transferring parent would take that into consideration.
