Money laundering is the process of making illegally obtained money appear legitimate. As a solicitor, you're a prime target for criminals who want to use legal services to "clean" dirty money — think property purchases, company formations, or trust arrangements.
This isn't just a compliance box-ticking exercise. If you fail to spot money laundering or don't report it, you could face criminal prosecution, unlimited fines, and up to 14 years in prison. The UK's anti-money laundering (AML) regime places specific obligations on solicitors as part of the "regulated sector."
Money laundering is heavily tested in FLK1. Focus on the POCA 2002 offence sections (ss.327-332), the reporting regime, and the difference between "knowledge" and "suspicion." You'll often get scenario questions where you need to decide whether a solicitor must report.
Money laundering typically follows three stages. Understanding these helps you spot when a client's transaction might be part of a laundering scheme. Not every laundering operation follows all three stages neatly, but knowing the pattern makes red flags easier to identify.
Solicitors are particularly vulnerable at the layering and integration stages. Property transactions, company structures, and trust arrangements are all attractive to launderers. If a client asks you to handle a transaction that seems unnecessarily complex or doesn't make commercial sense, that's a red flag.
The UK's AML regime sits within an international framework. The Financial Action Task Force (FATF), established in 1989, sets global standards for combating money laundering and terrorist financing. The EU's Money Laundering Directives have also shaped UK law, though post-Brexit the UK maintains its own regime aligned with international standards.
Sections 327 to 329 of POCA create three principal money laundering offences. These are sometimes called "direct involvement" offences because they criminalise actually dealing with criminal property. Each carries a maximum penalty of 14 years' imprisonment.
Before looking at the offences, you need to understand "criminal property." Property is criminal property if it constitutes or represents a person's benefit from criminal conduct, and the alleged offender knows or suspects that it constitutes or represents such a benefit (s.340 POCA). This is a very broad definition — it covers any property, anywhere in the world, derived from any criminal conduct.
Note the threshold is "knows or suspects." Suspicion is a low bar — it doesn't require certainty or even a belief on the balance of probabilities. In R v Da Silva [2006], the court said suspicion means a possibility (more than fanciful) that the relevant facts exist. You don't need to know the specific crime — just that the property might be criminal.
Under s.327, it's an offence to conceal, disguise, convert, or transfer criminal property, or to remove it from England and Wales, Scotland, or Northern Ireland. "Concealing or disguising" includes concealing or disguising its nature, source, location, disposition, movement, or ownership. For example, if you help a client convert cash from drug dealing into a property purchase, you're committing this offence.
Section 328 makes it an offence to enter into or become concerned in an arrangement which you know or suspect facilitates the acquisition, retention, use, or control of criminal property by or on behalf of another person. This is the offence most relevant to solicitors — if you act in a transaction that helps your client deal with criminal property, you could be caught by s.328.
Under s.329, it's an offence to acquire, use, or possess criminal property. There's a defence if you acquired, used, or possessed the property for adequate consideration — meaning you paid a fair market value for it. This defence is important for solicitors receiving fees, provided the fees are at a reasonable level for the work done.
| Section | Offence | Key Conduct | Maximum Penalty |
|---|---|---|---|
| s.327 | Concealing etc. | Concealing, disguising, converting, transferring, or removing criminal property | 14 years' imprisonment |
| s.328 | Arrangements | Entering into or becoming concerned in an arrangement facilitating acquisition, retention, use, or control of criminal property | 14 years' imprisonment |
| s.329 | Acquisition, use, possession | Acquiring, using, or possessing criminal property | 14 years' imprisonment |
Think of it this way: s.327 is about what you do TO the property (move it, disguise it); s.328 is about helping SOMEONE ELSE deal with it (facilitating arrangements); s.329 is about having it YOURSELF (acquiring, using, or possessing it). In an exam scenario, identify which section applies by asking: who is doing what with the criminal property?
The most important defence for solicitors is "authorised disclosure" under s.338 POCA. If you suspect you're dealing with criminal property, you can make a disclosure to the NCA (National Crime Agency) before the act takes place and obtain consent to proceed. If you make the disclosure and get appropriate consent (or the relevant time period expires without refusal), you have a defence to ss.327-329.
When you make an authorised disclosure (a SAR — Suspicious Activity Report) to the NCA, you enter the "consent regime." You must not proceed with the transaction until you receive consent from the NCA. If the NCA doesn't refuse consent within 7 working days, you can proceed. If they refuse, there's a further moratorium period of 31 calendar days during which you cannot proceed.
The consent regime timeline is a common exam point: 7 working days for the NCA to refuse after your SAR, then if they refuse, a further 31 calendar days moratorium. After both periods expire without a court order, you can proceed. Remember: 7 working days, then 31 calendar days.
The failure to disclose offences are separate from the principal offences. They don't require you to actually deal with criminal property — instead, they criminalise failing to report your knowledge or suspicion that someone else is laundering money. For solicitors in the regulated sector, s.330 is the key provision.
Under s.330, if you work in the regulated sector (which includes solicitors) and you know, suspect, or have reasonable grounds for knowing or suspecting that another person is engaged in money laundering, you must disclose this to your firm's MLRO (Money Laundering Reporting Officer) or directly to the NCA. The key difference from the principal offences is the additional "reasonable grounds" threshold — even if you don't actually suspect, you commit the offence if a reasonable person in your position would have suspected.
Section 330 includes an objective test: "reasonable grounds for knowing or suspecting." This means you can't simply close your eyes to suspicious circumstances. Even if you genuinely didn't suspect anything, you can be convicted if a reasonable person in your position would have been suspicious. This makes training and awareness critically important.
Section 331 applies to nominated officers (MLROs) in the regulated sector. If the MLRO receives a disclosure from someone in the firm (an internal report) or obtains information in the course of their role, and they know, suspect, or have reasonable grounds for knowing or suspecting money laundering, they must disclose to the NCA. The MLRO acts as the gateway between the firm and the NCA.
Section 332 applies to nominated officers outside the regulated sector. It mirrors s.331 but the mental element is "knows or suspects" without the additional "reasonable grounds" test. In practice, most solicitors will be concerned with s.330 (as individual fee earners) and s.331 (if they're the MLRO).
| Section | Who It Applies To | Mental Element | Maximum Penalty |
|---|---|---|---|
| s.330 | Persons in the regulated sector (including solicitors) | Knows, suspects, or has reasonable grounds for knowing or suspecting | 5 years' imprisonment |
| s.331 | Nominated officers (MLROs) in regulated sector | Knows, suspects, or has reasonable grounds for knowing or suspecting | 5 years' imprisonment |
| s.332 | Nominated officers outside regulated sector | Knows or suspects (no reasonable grounds test) | 5 years' imprisonment |
For s.330, you have a defence if you have a reasonable excuse for not disclosing, or if the information came to you in privileged circumstances. Legal professional privilege (LPP) is a defence — but only for information received in connection with giving legal advice or in connection with legal proceedings. Crucially, LPP does not apply if the information is communicated with the intention of furthering a criminal purpose.
The privilege defence is nuanced. If your client tells you in a genuine advice context that they have criminal property, privilege may protect you from the reporting obligation. But if the client is seeking your help to launder the property, the "crime/fraud exception" to LPP applies, and you must report. When in doubt, seek guidance from your MLRO.
Once you've made a disclosure (or you know one has been made), you must not tell anyone about it if that disclosure might prejudice any investigation. Under s.333A POCA, if you're in the regulated sector and you disclose to someone that a SAR has been made, and that disclosure is likely to prejudice an investigation, you commit an offence punishable by up to 2 years' imprisonment.
This means you cannot tell your client that you've reported them to the NCA. You also can't hint at it — for example, by saying "we can't proceed for regulatory reasons" in a way that might alert them. If the NCA refuses consent and there's a moratorium, you need to find a way to explain the delay without revealing the report. This is one of the hardest practical challenges in AML compliance.
Be very careful about what you say to clients when you've made a report. Even innocent-sounding explanations like "there's a compliance issue" could amount to tipping off if your client could infer a report has been made. If asked why a transaction is delayed, give a neutral explanation that doesn't hint at a SAR.
Under s.342 POCA, it's an offence to make any disclosure that is likely to prejudice a money laundering investigation, or to falsify, conceal, destroy, or dispose of documents relevant to such an investigation. This applies to everyone, not just the regulated sector. The maximum penalty is 5 years' imprisonment.
The Terrorism Act 2000 creates parallel offences to POCA but specifically targeting terrorist property. Sections 15-18 cover: fundraising for terrorism (s.15), use and possession of terrorist property (s.16), involvement in funding arrangements (s.17), and money laundering of terrorist property (s.18). These carry a maximum penalty of 14 years' imprisonment.
Section 19 creates a general offence of failing to disclose knowledge or suspicion of terrorist financing offences where the information came from your work. Section 21A applies specifically to the regulated sector and mirrors s.330 POCA — it includes the "reasonable grounds for knowing or suspecting" test. If you're in the regulated sector, s.21A is the relevant provision.
The key difference for exam purposes is that terrorist property doesn't need to come from criminal conduct — it could be perfectly legitimate money that's intended for use in terrorism. Under POCA, property must be derived from crime. Under the Terrorism Act, clean money earmarked for terrorist purposes is caught too.
Every law firm must appoint a Money Laundering Reporting Officer (MLRO), also called a nominated officer. If you suspect money laundering, your first step is to make an internal report to your MLRO. Don't try to investigate yourself and don't confront the client. The MLRO will assess whether an external report (a SAR) needs to be made to the NCA.
A Suspicious Activity Report (SAR) is the formal report made to the NCA. The MLRO submits SARs through the NCA's online system. The SAR should contain all relevant information: the client's identity, the nature of the suspicion, details of the transaction, and any supporting evidence. Speed matters — if a transaction is about to take place, you need consent before proceeding.
Ideally, you should report before any prohibited act takes place. If that isn't possible (for example, you only realise after the event), you should report as soon as practicable. A disclosure made after the act can still provide a defence if it's made on the discloser's own initiative and as soon as practicable.
Knowing when to be suspicious is crucial. You don't need proof of money laundering — you just need reasonable grounds for suspicion. The following indicators should put you on alert and may trigger a reporting obligation.
If something feels wrong, it probably is. The legal test is whether a reasonable person in your position would have suspected money laundering. Don't ignore gut feelings — document your concerns and speak to your MLRO. It's always better to report and be wrong than to fail to report and face criminal liability.
Customer Due Diligence is the process of verifying your client's identity and understanding the nature of their business relationship with you. Under the MLR 2017, you must carry out CDD before establishing a business relationship or carrying out an occasional transaction. The basic requirement is to identify the client and verify their identity using reliable, independent sources.
In higher-risk situations, you must apply Enhanced Due Diligence. EDD goes beyond standard checks and requires additional measures proportionate to the risk. You must apply EDD where there's a high risk of money laundering, when dealing with PEPs (Politically Exposed Persons), in non-face-to-face relationships, and when dealing with countries identified as high-risk by the FATF or the EU.
In lower-risk situations, you may apply Simplified Due Diligence, which allows you to reduce the extent of CDD measures. However, SDD is not available where there's any suspicion of money laundering or terrorist financing. Even with SDD, you must still identify the client — you just may be able to verify identity through less rigorous means.
A PEP is someone who holds or has held a prominent public function — for example, heads of state, senior politicians, senior government officials, judicial or military officials, or senior executives of state-owned enterprises. Family members and close associates of PEPs are also treated as PEPs. You must apply EDD to all PEPs and obtain senior management approval before establishing a business relationship.
If you can't complete CDD, you must not carry out the transaction or establish the business relationship. You should also consider whether to make a SAR to the NCA. Don't be tempted to proceed on the basis that you'll "complete the checks later" — the regulations require CDD before you act, not after.
Under the MLR 2017, your firm must carry out a written risk assessment identifying and assessing the risks of money laundering and terrorist financing that it faces. This must take into account the firm's clients, the countries it operates in, the products and services it offers, its transactions, and its delivery channels. The risk assessment must be kept up to date.
Your firm must establish and maintain policies, controls, and procedures to mitigate and manage the risks identified in its risk assessment. These must cover CDD, reporting, record keeping, internal controls, risk management, and compliance management. The policies must be approved by senior management and communicated to all relevant employees.
You must keep copies of CDD documents (or references to the evidence of identity) for five years after the end of the business relationship or the completion of the occasional transaction. You must also keep records of transactions sufficient to permit reconstruction of individual transactions for five years from completion. These records may be needed by law enforcement.
Your firm must ensure that all relevant employees receive regular training in how to recognise and deal with potential money laundering and terrorist financing. This includes understanding the firm's AML policies, knowing how to identify suspicious activity, and understanding the reporting obligations. Training must be provided at induction and then regularly updated.
In scenario questions, work through a checklist: (1) Is there criminal property or terrorist property? (2) Which offence might apply? (3) Does the solicitor have knowledge, suspicion, or reasonable grounds? (4) Has a report been made? (5) Is there a defence available? (6) Is there a risk of tipping off? This systematic approach will help you tackle even the trickiest questions.
