SOF Verification - Source of Funds
Source-of-funds checks concern where money used for gambling came from.
Identity and financial checks
The KYC guide explains identity checks. A source-of-funds request may instead ask for evidence connecting money to its origin, such as income or savings. Ask the operator what it needs, why it needs it and how to submit it securely.
Timing and withdrawals
A withdrawal request does not make every new document demand justified. For businesses licensed in Great Britain, the Gambling Commission says information that could reasonably have been requested earlier should not first become a condition of withdrawal. Other legal obligations may require further checks. This is a British regulatory example, not a worldwide rule. See the Gambling Commission’s verification guidance.
If a request is unclear
Ask for a written explanation and an expected response date. Keep copies of the request and your correspondence. Use the operator’s official secure channel and complaint process. Check the complaints arrangements for its actual licence if the issue remains unresolved. Providing documents does not guarantee a particular payment date. Our withdrawals guide explains other steps in the process.
