What is a source of funds check and when might a casino request it?

Short Answer: A Source of Funds (SOF) check is an advanced verification step triggered by large deposits or suspicious activity. It is an Anti-Money Laundering (AML) requirement where you must prove that the money you are gambling with comes from a legitimate source.

1. The Threshold Trigger

This check rarely affects casual players. It typically kicks in for 'High Rollers' who deposit large sums (e.g., R50,000+ in a month). The casino is legally obligated to ask: "Where did this money come from?" to ensure they are not laundering proceeds of crime.

2. Required Documents

You may be asked to provide 3 months of bank statements (showing salary deposits), a payslip, proof of inheritance, or documents showing the sale of an asset. While intrusive, it is a standard legal compliance step for high-value accounts.
