What is the difference between Source of Funds(SOF) and Source of Wealth (SOW)?

SOF and SOW are not the same thing. Establishing SOF relates to the identification of where the money comes from, whereas on the other hand SOW refers to a person’s overall wealth. SOW verification requires us to look more deeper, player who accumulated their wealth can show, for example, tax declarations, savings from their salary, inheritance, large winnings from casinos, etc.
