What is Source of Funds (SOF)?
Source of Funds (SOF) is the origin of a specific deposit or transaction, the money that lands in your account. We need to understand not only where the funds came from, but the activity that generated them.
What is Source of Wealth (SOW)?
Source of Wealth (SOW) refers to how a person has built their overall wealth, not just one transaction. The key question is why the client has the assets they do, and how they came to accumulate them over time.
What is the difference between SOF and SOW?
- SOF is about the origin of a specific deposit or set of funds.
- SOW is about a client's overall wealth and how it was accumulated.
To comply with financial regulations and confirm that funds and assets are legitimate.
What should I do if my document is older than 3 months?
Documents should generally be recent, issued within the last 3 months, unless they evidence a historic event such as an inheritance or a property sale. If your document is older, please provide a more recent one or contact customer support for guidance.
Can I submit screenshots of online banking as proof?
We do not accept screenshots of online banking. Please provide official bank statements (PDF or paper statements issued by your bank).
