What is AML Screening?
In brief: AML screening checks clients, beneficial owners, and relevant parties against risk data such as sanctions, PEPs, adverse media, and watchlists.
Key points
- AML screening helps identify sanctions, PEP, adverse media, and other risk indicators.
- A match is not always a true match, so false positives need review and evidence.
- Screening should be linked to onboarding, ongoing monitoring, and client risk assessment.
What is AML screening?
AML screening is the process of checking clients, beneficial owners, directors, controllers, and other relevant parties against risk data. That can include sanctions lists, politically exposed person data, adverse media, watchlists, and other financial-crime indicators.
For UK accountants and law firms, screening is not just a search box. It is part of client onboarding, risk assessment, ongoing monitoring, and audit-ready evidence.
What should be screened?
Depending on the matter and risk, firms may need to screen:
- Individual clients.
- Company clients.
- Directors, partners, trustees, or equivalent controllers.
- Persons with significant control and ultimate beneficial owners.
- Third-party funders or counterparties where relevant.
- Existing clients when risk changes or periodic review is due.
Main screening categories
| Category | What it helps identify |
|---|---|
| Sanctions | Whether a person or entity appears on a relevant sanctions list. |
| PEPs | Whether a person is politically exposed or connected to a PEP. |
| Adverse media | Public information that may indicate financial crime or reputational risk. |
| Watchlists | Additional risk data from public, regulatory, or specialist sources. |
False positives
Screening often produces possible matches that are not true matches. A good review process checks:
- Name similarity.
- Date of birth.
- Country and address.
- Role or occupation.
- Associated entities.
- Source list and date.
- Why the match was cleared or escalated.
Do not simply delete false positives. Keep a short record explaining the decision.
When to screen
Screening should happen:
- Before onboarding a new client.
- When beneficial ownership or control changes.
- When a new matter or transaction changes risk.
- During periodic reviews.
- When new sanctions or risk data may affect existing clients.
What to record
An audit-ready screening record should show:
- Who or what was screened.
- Which data sources or tool were used.
- Date of screening.
- Results returned.
- Review notes for possible matches.
- Decision and escalation outcome.
- Next review trigger.
Screening and client risk assessment
Screening results should feed into the client risk assessment. A PEP match, sanctions concern, adverse media result, or unresolved watchlist hit should change the risk conversation and may require enhanced due diligence, senior approval, refusal, or exit.
