Agree the question before assembling the evidence
A useful review starts with an agreed scope: the legal entities, business lines, relevant period, regulatory concerns, controls and intended audience. Identify the applicable rules and guidance for that business. FCA authorisation does not by itself mean every provision of the Money Laundering Regulations applies to every activity; applicability needs to be established.
Agree whether the work assesses control design, historical operation, current implementation, sustained effectiveness or a combination. Set out the reviewer’s access, sampling method, deliverables, limitations and process for management responses. Where the reviewer has helped implement controls, assess independence and conflicts explicitly; a different reviewer or independent challenge may be needed.
Prepare the programme and the population
Collect current and relevant historic versions of the business-wide risk assessment, customer-risk methodology, policies, procedures and governance records. Include approval and effective dates. Supply organisation charts, accountable roles, training arrangements, management information, audit work and the remediation tracker. A Board pack shows what information was presented; minutes and action records help explain the decisions and follow-through.
For file testing, reconcile the population first. Identify the source, extraction date, products, risk bands and key exclusions. Preserve duplicates and relationships as explicit mappings rather than quietly removing inconvenient records. A risk-based sample can examine higher-risk situations and control changes, but its findings should not be projected across the book as a statistical error rate unless the sampling design supports that.
- Confirm scope, applicable standards and review independence.
- Index policies, governance and system evidence by date.
- Reconcile the population before selecting files.
- Agree how later evidence and management responses will be assessed.
Provide operating records, not just a demonstration
A walkthrough is valuable for understanding a process, but it does not establish that the process operated for a particular customer at an earlier date. Pair demonstrations with attributable audit trails, verification results, screening decisions, risk assessments, transaction records and review histories. Keep a screenshot where it answers the point; supply the underlying document when its contents are the evidence.
Testing should be proportionate to the risk and relevant obligations. Do not assume every customer needs a full wealth pack or that every high-risk relationship has the identical statutory approval requirement. Separate enhanced measures under regulation 33, the specific PEP provisions and any stricter internal policy. General four-eyes onboarding approval may be a firm control rather than a universal legal rule.
Make challenge constructive and closure traceable
The reviewer should credit new evidence and clear management explanations, including evidence that disproves an initial concern. Use a point-by-point response process: what was said, what was supplied, what it proves, what remains and why. Avoid repeatedly asking for an item already present in a workbook, archive or earlier pack.
MEMA’s recommended output distinguishes historic gaps, current controls and residual work. A historic gap may remain a fact even when today’s control has improved; equally, it must not automatically be presented as an ongoing failure. Before reporting, reconcile the findings, responses, actions and summary. Ask the reviewer to state the proof boundary clearly: what was tested, what was not and what requires later effectiveness testing.
A fictional worked example
The starting point
Our new onboarding procedure demonstrates that the historic file issue is fixed.
A more useful approach
The approved procedure explains the redesigned control. Recent attributable records show its application; the historic record limitation is separately identified and the agreed effectiveness test remains scheduled.
Design, implementation, historic compliance and sustained operation are tested separately.

Questions on this topic
8 questions
Is an independent compliance review the same as a section 166 review?
No. A section 166 skilled person review uses a specific statutory power and appointment process. A firm-commissioned independent review is not automatically a statutory skilled person review.
Confirm the legal basis and agreed scope. MEMA’s educational resources do not imply that MEMA is appointed to a skilled-person panel or authorised to undertake every statutory engagement.
What documents are needed for a financial-crime review?
Usually the relevant risk assessments, current and historic procedures, governance records, population data, selected case files, audit histories, screening decisions, monitoring evidence and remediation records.
The exact list depends on the business and scope. Supply source dates and management responses alongside the documents, and preserve evidence of actual operation rather than only the latest policy.
Does every client file need to be reviewed?
Not automatically. Agree a defensible population and sampling approach based on the concern, risks, applicable requirement and any need for a wider look-back.
Some issues require a complete affected-population exercise. A risk-based sample can identify weaknesses but should not be presented as a statistically representative error rate unless its design supports that conclusion.
What should an independent review report deliver?
A clear scope and methodology, evidence considered, reasoned findings, management responses, limitations and a prioritised remediation plan with objective closure tests.
It should distinguish historical compliance, current implementation and sustained operation. A report should state what has actually been verified and must not imply regulatory acceptance merely because the review is complete.
What does an AML and financial-crime review cover?
Scope can include risk assessment, governance, customer due diligence, enhanced measures, screening, monitoring, training, record keeping and assurance. Broader financial-crime risks may also be relevant.
Start with the activities and obligations that apply to your firm. An AML checklist is not a substitute for assessing sanctions, fraud or other material risks where those are in scope.
Does every higher-risk customer need the same enhanced due diligence?
No. Enhanced measures must reflect the relevant requirements and risk. The specific PEP provisions and the firm’s own approval policy should not be confused with an identical statutory package for every higher-risk customer.
Explain why the measures are appropriate, what was done and who made the decision where approval is required. A high-risk label without a reasoned response is not enough.
What makes a screening match decision defensible?
An attributable record of the report reviewed, relevant identifiers compared, evidence considered, rationale and the required decision or escalation. A bare “false positive” label may not explain the assessment.
Do not dismiss a result solely because the original search omitted an identifier that appears elsewhere in the file. Escalate sanctions concerns under the applicable regime and procedure; a vendor score is not a legal decision.
What is the difference between source of funds and source of wealth?
Source of funds concerns the origin of money involved in a relationship or transaction. Source of wealth concerns how the person accumulated their overall wealth.
The enquiries and supporting evidence should reflect the applicable obligation and risk. A bank receipt may show a payment arrived without explaining its economic source; a full wealth pack is not automatically required for every customer.

How MEMA can help
We can help interpret the scope, organise evidence, test controls or deliver a defined remediation workstream. Where independent assurance is required, the scope and reviewer separation are agreed explicitly.
