Money Laundering Examples for UK Accountants and Law Firms
In brief: Money laundering examples become useful when they help a firm connect unusual facts to a clear risk assessment, evidence request, and escalation decision.
Key points
- Look for mismatches between the client's profile, money movement, documents, and commercial rationale.
- Examples are risk indicators, not automatic proof of criminal conduct.
- The right response is proportionate evidence, documented reasoning, and escalation where suspicion may exist.
Why examples matter
Money laundering is often described with bank, casino, or crypto examples. Those can be useful, but UK accountants and law firms need examples that look like ordinary client work: bookkeeping, accounts, tax advice, company structures, property transactions, probate, payroll, and business disposals.
The examples below are not proof on their own. They are prompts for better questions and better records.
Example 1: director loan with weak evidence
A new company client explains that a large amount of working capital came from a director loan. The bank statement shows funds arriving from another individual or overseas entity, but the client cannot explain the relationship clearly.
What to check:
- Who provided the money?
- What is the relationship to the client or company?
- Is there a loan agreement?
- Does the lender have a plausible source of funds?
- Does the ownership or control position need updating?
Example 2: cash-heavy business with changing explanations
A client runs a cash-intensive trade. Turnover increases sharply, margins change, and explanations differ between the director, bookkeeper, and bank narrative.
Risk indicators include:
- Cash deposits inconsistent with stated opening hours or staffing.
- Unexplained third-party payments.
- Frequent corrections to sales records.
- Pressure to file quickly without supporting documents.
- Resistance to ordinary bookkeeping questions.
Example 3: complex structure without commercial purpose
A client uses several companies, nominee-like roles, or overseas entities. Complexity is not automatically suspicious, but it becomes a concern when nobody can explain the commercial reason for the structure or who ultimately benefits.
The firm should document beneficial ownership, control, purpose, and source of wealth before accepting high-risk work.
Example 4: property or asset purchase funded by several parties
A buyer funds a transaction from multiple accounts or third parties. The explanation may be legitimate, but the firm needs to understand source of funds and the relationship between contributors.
Ask for evidence that proves the route of funds and the reason each party is involved.
Example 5: invoices that do not match the business
A business receives or pays invoices for services that do not fit its trade, location, staffing, or capability. The invoice may look formal but still lack a credible commercial basis.
Evidence to request may include contracts, delivery records, correspondence, proof of service, or board approval.
Example 6: money mule behaviour
An individual or small business appears to receive funds and quickly pass them on, keeping a small amount or claiming to help someone else. The client may describe this as a favour, investment, platform activity, or informal payment service.
The risk is higher where the client lacks knowledge of the payer, payee, purpose, or economic reason.
What to document
For each concern, keep a concise audit trail:
| Area | Evidence |
|---|---|
| Client profile | Expected activity, occupation, business model, and risk rating. |
| Transaction facts | Amounts, dates, counterparties, accounts, and documents reviewed. |
| Explanation | What the client said and whether it changed. |
| Checks | Identity, ownership, source of funds, source of wealth, screening, and open-source checks. |
| Decision | Continue, request more evidence, pause, decline, exit, or escalate. |
When to escalate
Escalate internally when the facts create suspicion, when evidence does not support the explanation, or when the client tries to avoid ordinary AML checks. Do not tell the client that a suspicious activity report may be considered.
