What is Source of Funds and Source of Wealth?

Definition: Source of funds (SoF) is the origin of the money a player uses for deposits. Source of wealth (SoW) is how the player built up their overall wealth.

The difference in practice:

  • SoF answers where this specific money came from, e.g. salary paid into the account used for deposits.
  • SoW answers how the player's total assets were accumulated, e.g. business ownership, inheritance or property sale.

Typical documents:

  • Payslips or employment contracts.
  • Bank statements.
  • Tax returns or company accounts.
  • Property sale or inheritance documents.

When it is requested: as part of enhanced due diligence, when deposits pass set thresholds or when transaction monitoring flags an account.
