Now a days many casinos are pretending in a way to pay out the due winning claims of various player, casinos are asking for different types of legal requirements to be fulfilled without which they are refusing to pay out the due claims. However there is no legal reasons for online casinos to hinder the claims payout of players.
There is casinos strategy behind not paying the due claims because they think that player will use their reserve fund(which is always available), to play for one more chance. They always hope that between the payout time and the actual time when payment happens, might be the p[layer will go for one more game.
There is strategy of some casinos that they provide bonus money but they never make it clear that you need to play with that money before you move to have a payout. Here player is bound to play for further more times until you  don’t finish that extra money. Some good casinos indicates it clearly at the initiation of the game, that how much you can go for cash out and how much more you need to play before you choose the option of payout.
It should be cleared to everyone that online casinos can take up to 12 months of time to pay you out, so you can’t ask them to pay you early. At least before one week you should hope for the cash out.
If casino is claiming that they are facing some legal reasons due to which they are not processing your money, then ask them to provide you that legal reasons through mail or letter.
Finally it is good to choose that particular online casino which has a good reputation and never make any delay in the payout.
