Working out "casino withdrawal pending" means knowing which question is being asked. Money goes in with almost no questions and comes out with several, and that asymmetry catches most people at their first withdrawal. A casino is obliged to know who it is paying, where that person lives and where the money being staked came from, and it usually asks at the moment it is about to pay rather than when the account opened. Knowing which three checks exist, and what satisfies each, turns a stalled payout into a short errand.
Source of funds is the third and the one people find intrusive. It asks where the money being gambled came from, and the answer is a document rather than a sentence: payslips, a tax return, a contract of sale, a statement showing the deposit arriving from a named employer. A salary is a perfectly ordinary answer and so is a pension, a redundancy payment or a house sale. What fails is an answer with no paper behind it, because the check is not asking whether the story is plausible.
Proof of address is the second, and the document that satisfies it is dated. A council letter, a bank statement or a utility bill from the last three months carries a name and an address on the same page, which is the whole point of it; a bill from last year does not. Screenshots of online banking usually pass where they show the bank's name, the account holder and the address together, and fail where they show only a balance.
The order matters less than the timing. Identity and address are often asked once and never again; source of funds arrives later, usually when the totals passing through an account cross a threshold the operator does not publish. A payout that has sat pending for days while nothing was requested is worth a question to support, because a check waiting on a document nobody asked for is the commonest reason one stalls.
Quick answers
What happens to the balance if an account is frozen?
The account is usually frozen rather than closed, the balance held until the source of funds is shown, and deposits are normally returnable to their origin.
What does a source of funds check ask for?
Documents rather than explanations: payslips, a tax return, a contract of sale or a statement showing money arriving from a named employer.
Which answers to a source of funds check are acceptable?
A salary, a pension, a redundancy payment or a house sale are all ordinary answers, provided paperwork backs them up.
Which document proves identity for a casino payout?
A passport, driving licence or national identity card with a photograph, full name and date of birth, photographed with all corners in frame and legible text.
Why might a payout stay pending when nothing was requested?
A stalled payout is most often a check waiting on a document nobody has asked the player for, so a question to support is worthwhile.
