You need to complete a de-registration form, which can be found below.
Please see the notes on the de-registration form as you will need to provide the players ID card and SAE of the players address.
When a player is de-registered, the League send them an exit form. For your records you can see an exit form below.
If the player is wanting to join another club, then he should do a League transfer. Any player who is de-registered during the season will stand a Sunday should they join another team that season. If a player is transferred, then they can play straight away.
