Two phrases sit next to each other in almost every enhanced due diligence procedure, and a surprising number of firms use them as though they meant the same thing. They do not, and the difference is not academic. A file that verifies one and records it as the other is a file with a gap in it, and it is a gap supervisors know to look for.
The distinction
Source of wealth is about the customer’s overall economic history. It asks how this person came to have the assets they have — the business they built and sold, the inheritance, the career, the property, the shareholding. It describes the activities that generated, or contributed significantly to, the whole of the customer’s net worth. It is a question about a life, not a transaction.
Source of funds is narrower and more immediate. It asks where the specific money in front of you came from: this subscription, this transfer, this deposit. Which account it left, what it was before it was in that account, and how it got there.
A customer can give a perfectly good answer to one and a poor answer to the other. Someone with an entirely explicable fortune can still be moving money that did not come from it. Someone whose particular payment traces cleanly to a named account may have no credible account of how they came to have that much in the first place.
Why they have to be read against each other
The reason both questions exist is that the answers are supposed to reconcile.
Source of funds that cannot be squared with what you know about source of wealth is a risk signal in itself. A client whose declared wealth is a modest professional career, subscribing seven figures from a company account in a jurisdiction unconnected to anything else in the file, has not necessarily done anything wrong — but the file cannot say it is consistent, and consistency is the thing the check is for.
That is the practical test to apply. Not “did we ask?” but “do the two answers fit together, and does the file show why we thought so?”
What actually counts as evidence
This is where most procedures are weaker than they read.
A declaration is not evidence. A form on which the investor writes “sale of business, 2019” records an assertion. It tells you what the customer says. It does not establish anything, and a file built entirely on declarations is a file of claims.
Corroboration is what turns it into evidence, and how much you need scales with risk. For a straightforward relationship, a coherent account plus something that supports it may be enough. For a politically exposed person, a high-risk jurisdiction, or a structure whose complexity has no obvious commercial explanation, considerably more is expected — and “expected” here means the firm’s own risk assessment should already say so.
Useful corroboration tends to be documentary and independent: filed accounts and the public record of a company sale; a share register; a grant of probate; contracts of employment or audited remuneration; property records; a court judgment. What these have in common is that they exist independently of the customer, and can be checked later by someone who was not in the room.
The public record does a specific job here that internal documents cannot. It is where you find out whether the business that supposedly generated the wealth existed, when it was sold, whether the sale was reported, whether the counterparty is who the customer says, and whether there is litigation, insolvency or enforcement attached to any of it. A bank statement shows you the money arriving. It cannot tell you the story behind it is true.
Where the check breaks in practice
Asking the question and filing the answer. The commonest failure. The procedure says obtain source of wealth, the analyst obtains a sentence, and the sentence goes in the file unexamined. Nothing in the record shows anyone tested it.
Verifying the funds and calling it wealth. The payment traced to an account in the client’s name, the check marked complete. Tracing the last hop establishes source of funds, weakly, and source of wealth not at all.
Stopping at the plausible. The account offered is reasonable, so it is accepted. Plausible is not the standard when the risk is high; the standard is corroborated, and the difference between those two words is most of the work.
No date, no scope. The file says the wealth was verified. It does not say what was searched, on what spelling, or when — so when the same question is asked three years later the answer has to be rebuilt from nothing.
Never revisited. Wealth was established at onboarding and the relationship has run for six years since. Ongoing monitoring includes keeping the underlying information current, and a source of wealth picture from 2020 is not a current one.
Making it defensible
The file should be able to answer, without the analyst present: what was claimed, what independently supports it, what was searched and when, what was not found, and who concluded that the two answers reconcile.
The last two matter more than they look. Where nothing is found, the file should say nothing was identified in the sources searched — not that the customer is clean, which is a much larger claim than any search supports. And a named person should own the conclusion, because reconciling wealth with funds is a judgement, and judgements need someone who made them.
Assembling that evidence is the slow part, and it is the part EyesClear Investigations is built for: it screens a company or a person against public sources and returns each finding with the verbatim quote, its source and its date, so what supports the wealth story is quotable rather than remembered. It states explicitly when nothing was identified, and the published methodology sets out what a screening cannot establish as plainly as what it can — including that it cannot prove a negative.
The conclusion stays with your analyst. The tool gathers; a person decides and signs.
