Firstly, welcome to the forum!
So as far as documentation goes, there are two main categories:
- identity - this is done at account creation, and tends to only be requested again when there's a trigger (new address, document expiry etc).
- financial - this is done based on your financial background, so some customers won't be asked at all, others will be reviewed periodically (e.g. 3, 6 or 12 months).
They can ask for documentation for a variety of reasons - but also some operators (or "casinos") have been exploiting this as a "stealth reverse" mechanic by asking for documentation at the point of withdrawal to slow the player down and hope they will play the money back.
While the CDD request is active, you are allowed to deposit and play, but crucially you
cannot withdraw.
Furthermore, if you refuse and/or fail the CDD check (at the discretion of the operator), they
must close your account and should return all funds at the time of the check plus any subsequent deposits - you'll notice this doesn't include any subsequent winnings, which are likely to be forfeit (and why operators love it - because the player is anti-freerolling themselves).
The
is crystal clear on this and why it is crucial you
stop playing when you receive such a request:
So they
should return your funds if you refuse - but they will close your account as well.
I would not use the self-exclusion mechanism for this, because it can have a lot of unintended consequences:
- If the site has sister properties, those should also exclude you.
- If the site belongs to the GamProtect trial, they may refer you to that and you'll be excluded from all sites participating in the trial (currently Flutter, Entain, Bet365 and WH, but they are looking to expand it in the future) with minimal rights to object.
