Source of wealth, evidenced rather than asserted
Two terms that get used interchangeably and mean different things. Confusing them is one of the more reliable ways to build a file that looks complete and satisfies nobody.
/ The distinction, and why it matters
Source of funds is the origin of the specific money moving through the relationship — this deposit, this wire, this subscription. It is narrower, more immediate, and usually easier to evidence.
Source of wealth is the origin of the customer's overall net worth — how they came to have money at all. It is the harder question, and it is the one that exposes a mismatch between who someone says they are and what the record shows.
A customer can have entirely legitimate source of funds for a particular transaction while their source of wealth remains unexplained. Programs that establish only the former, for relationships that warrant both, tend to discover the gap at examination rather than at onboarding.
/ When each is expected
Source of funds is a routine part of understanding expected activity. Source of wealth becomes material where the relationship carries elevated risk — typically the same population that warrants enhanced due diligence:
- Politically exposed persons and their close associates
- Private banking and wealth relationships above your defined threshold
- Customers whose wealth is attributed to jurisdictions with limited public records
- Relationships where activity has diverged materially from what was expected
- Beneficial owners behind entity customers in higher-risk categories
/ What evidence actually satisfies a reviewer
The test is not how many documents you hold. It is whether an independent reviewer can trace the stated wealth to something verifiable, and whether the scale reconciles.
- Corporate records showing ownership and the timing of a disposal or dividend
- Filed accounts, audited where available, supporting a stated business income
- Property and land registry records consistent with declared holdings
- Court records, probate, or settlement documentation for inherited or awarded wealth
- Regulatory filings and disclosures for listed-company executives
- Contemporaneous media or public reporting corroborating a stated event
/ Why attestation alone fails
The single most common weakness is a source-of-wealth field populated with what the customer said, and nothing behind it. It fails for a simple reason: it tests nothing. If the customer is misrepresenting their wealth, an attestation captures the misrepresentation rather than detecting it.
The expectation is proportionality — corroboration in line with the risk. For a moderate-risk relationship that may be a single supporting document. For a PEP with wealth attributed to a private business in an opaque jurisdiction, it means establishing whether that business exists, when it was formed, whether the timeline supports the claimed proceeds, and whether the public record contradicts any of it.
/ Where the record runs out
Source of wealth work often reaches a point where the documentary trail stops and someone has to go looking. Corporate registries in multiple jurisdictions, filing histories, dissolved-and-refiled entities, shared registered agents, property records, litigation history — the structural detail that reveals whether a stated origin holds together.
AM Forensics performs that work: a written report tracing what the open record supports, stating plainly where it goes opaque and why, with each assertion cited. Written to be filed as the source-of-wealth record rather than summarised into one.
