Enhanced Due Diligence: Source of Funds & Source of Wealth

What triggers Enhanced Due Diligence?

EDD is a deeper, more rigorous form of customer due diligence. It is applied when a client or transaction carries higher risk – for example, politically exposed person (PEPs), complex ownership structures, offshore investors, or unusually large transactions. It’s designed to give reporting entities greater visibility into who they’re dealing with, where the money is coming from, and whether there are hidden risks of money laundering or terrorist financing.

Unlike standard checks, EDD requires gathering and verifying additional layers of information, including Source of Funds (SoF) and Source of Wealth (SoW). These insights allow you to build a clear picture of your client’s financial background, so you can easily identify potential risks, and confidently demonstrate to the supervisor that you understand both the immediate transaction and the broader origins of the customer’s wealth.

Source of Funds (SoF) vs. Source of Wealth (SoW)

At first glance, SoF and SoW can seem interchangeable, since each examines aspects of a client’s financial background. The realitiy is that they answer very different questions: SoF focuses on the specific money being used in a transaction, while SoW looks at the bigger picture of how your client built their overall financial position.

Because of this difference, the supervisor treats SoF and SoW as separate, but complementary requirements. Together, they provide a complete picture that helps businesses demonstrate they understand both the specific funds being used and the client’s broader financial background.

In practice

Think of SoF and SoW as two pieces of the same puzzle. For example:

• In Real Estate: SoF could be a deposit from a recent property sale, while SoW might involve evidence of a long career in business or a portfolio of rental properties.
• In Financial Services: SoF might be a bank statement of earnings (subject to transaction type and associated risk) for an investment, while SoW demonstrates that the client’s total wealth comes from legitimate earnings and not hidden sources.
• In Law & Accounting: SoF could be the funds from a trust distribution or settlement, while SoW may involve documentation showing overall portfolio how a family built its wealth over generations.

By addressing both aspects, you give the supervisor, and yourself, confidence that your client’s money is clean, consistent, and compliant.

Why this matters to the DIA – and your business

The Financial Action Task Force (FATF) and the supervisor highlight SoF and SoW as critical safeguards for effective AML/CFT programmes. They expect businesses to apply a risk-based approach, so the depth of the client review should match the level of risk. A PEP or client moving funds from a high-risk jurisdiction will attract more scrutiny than a long-standing client with a straightforward profile.

Getting this balance right is about preventing your business from being used for money laundering, protecting your reputation and building regulator confidence.

The challenge, of course, is putting this into practice. Completing these checks thoroughly and keeping records can quickly overwhelm in-house teams, which is where specialist support can make the difference.
