Knowing which account a transfer came from is useful. It does not, by itself, explain how the money was earned or how the investor accumulated their wealth. A clear file separates those questions before trying to answer them.
Begin with the question being asked
Source of funds concerns the underlying economic origin of the money used for a particular transaction. Source of wealth concerns how a person accumulated their overall assets. The path of funds records the movements linking the relevant source to the proposed investment.
AUSTRAC’s public guidance makes the distinction between the specific origin of transaction funds and the origins of a person’s broader wealth. Its guidance addresses Australian regulation; it is referenced here for terminology, not as a statement of U.S. legal requirements.
An investor plans to invest proceeds from a property sale. The sale may explain the immediate source of the investment funds. The property’s acquisition and the resources used to buy it may raise a separate question about the earlier origin of that capital. Transfers through two accounts explain the route, not the economic origin.
Give each question its own evidence
| Question | Potentially relevant records | What remains to check |
|---|---|---|
| What generated this money? | Sale agreement, closing statement, payment record | Whether the records connect the transaction to the actual receipt |
| How was the underlying wealth accumulated? | Acquisition history, earnings records, business distributions | Whether the explanation is supported over the relevant period |
| How did the funds move? | Sending and receiving statements, transfer references | Ownership of accounts, amounts, dates and any unexplained steps |
Avoid writing beyond the evidence
A sale agreement establishes what the parties recorded, but it does not alone establish that the price was paid. An account balance shows available funds at a point in time, but does not alone establish their origin. A client’s explanation may help identify which records to obtain; it should be identified as an explanation until supported.
For a practical handover, assign each material statement a document reference and record anything unresolved alongside it. Do not turn a plausible narrative into a verified conclusion by using stronger language.
Agree on the depth of the inquiry
Ask counsel or the intended recipient what question the file must answer, which period is relevant, and whether an earlier acquisition needs to be traced. There is no universal document list that answers every transaction, bank review, or immigration matter.
The objective of document preparation is to make the record understandable and its limits visible. It does not replace the recipient’s review or a legal assessment.
