Working out "source of funds checks" 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 an afternoon’s errand.
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 a balance is all they show.
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.
Common questions
How recent must proof of address be?
A bank statement, utility bill or council letter from the last three months, showing the name and address on the same page.
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.
Are online banking screenshots accepted as proof of address?
Usually, when they show the bank's name, the account holder and the address together; a screenshot showing only a balance fails.
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.
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.
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.
