Professional & Financial Services UK-wide

Law firms in England and Wales that carry out work within the scope of the Money Laundering Regulations 2017 (MLR 2017) must comply with anti-money laundering (AML) requirements. The legal sector is classified as high-risk in the UK National Risk Assessment because solicitors handle large transactions, manage client accounts, create legal structures, and facilitate property purchases — all of which can be exploited to launder the proceeds of crime.

This guide covers what is specific to solicitors and law firms. It does not repeat the general AML obligations that apply to all regulated businesses. If you are new to AML compliance, start with the generic AML guidance before reading this sector-specific guide.

When this applies to your firm

Your firm falls within the scope of the MLR 2017 if it provides any of the following services as an independent legal professional:

  • Buying and selling real property (conveyancing, commercial property)
  • Buying and selling business entities (mergers, acquisitions, share transfers)
  • Managing client money, securities, or other assets
  • Opening or managing bank, savings, or securities accounts
  • Creating, operating, or managing trusts, companies, or similar structures
  • Providing tax advisory services involving the above

Practice areas that typically do not fall within scope include family law (unless involving financial settlements channelled through the firm), criminal defence, personal injury, and employment law. However, if any in-scope work is carried out by any part of the firm, the entire firm must have AML policies and procedures in place.

Firm-wide risk assessment

Before undertaking any work within the scope of the MLR 2017, your firm must complete a written firm-wide risk assessment. This is not a box-ticking exercise. The SRA expects the assessment to reflect your firm's actual practice, client base, and geographic exposure — not a generic template downloaded from the internet.

The firm-wide risk assessment is distinct from the client and matter risk assessments you carry out on individual instructions. It looks at your firm as a whole and determines where the greatest AML risks lie so you can direct your controls accordingly.

High-risk areas for law firms

Certain types of legal work carry higher inherent money laundering risk. Your firm-wide risk assessment and your client and matter risk assessments must reflect these elevated risks, and you must apply enhanced controls where they are present.

Client due diligence in practice

Client due diligence (CDD) must be completed before you establish a business relationship or carry out an occasional transaction within the scope of the MLR 2017. For law firms, this means before you begin substantive work on an instruction, not at the point of completion.

Source of funds in conveyancing

For every property purchase, you must verify the source of the funds being used. This goes beyond simply identifying where the money is being transferred from. You must understand how the client acquired the funds. Common sources include:

  • Sale of an existing property (verify through linked transaction records)
  • Mortgage (verify through the lender's offer letter)
  • Savings (verify through bank statements showing accumulation over time)
  • Gift from a family member (obtain a signed gift letter and verify the donor's source of funds)
  • Funds from overseas (verify through overseas bank statements, tax records, or employment documentation)
  • Inheritance (verify through grant of probate or estate accounts)

A client stating "savings" or "from my account" is not sufficient verification. You must obtain documentary evidence that supports the explanation. Where funds come from multiple sources, verify each one separately.

Trust and company service provider (TCSP) duties

If your firm creates companies, establishes trusts, provides nominee shareholders or directors, or provides a registered office address, you are acting as a trust and company service provider. TCSP activities attract specific CDD obligations under Regulation 12 of the MLR 2017, including identification and verification of all beneficial owners of the structures created. Given the opacity risk of complex structures, the SRA pays particular attention to TCSP work during supervisory reviews.

Enhanced due diligence

You must apply enhanced due diligence (EDD) in higher-risk situations. For law firms, the most common EDD triggers are:

  • Clients who are politically exposed persons (PEPs), their family members, or known close associates
  • Transactions involving high-risk third countries identified by the FATF or the UK government
  • Complex or unusually large transactions with no apparent economic or legal purpose
  • Non-face-to-face client relationships where the client has not been met in person

EDD requires senior management approval to establish or continue the business relationship, enhanced ongoing monitoring, and establishment of the source of wealth (the overall origin of the client's financial resources, not just the funds for the specific transaction).

Legal professional privilege and suspicious activity reporting

Solicitors occupy a unique position in the AML regime because of legal professional privilege (LPP). Understanding the boundary of this privilege is critical to complying with your reporting obligations without inadvertently breaching client confidentiality or, conversely, failing to report when required.

The general reporting obligation

Under section 330 of the Proceeds of Crime Act 2002 (POCA), a person in the regulated sector who knows, suspects, or has reasonable grounds for knowing or suspecting that another person is engaged in money laundering must submit a suspicious activity report (SAR) to the National Crime Agency (NCA) through the firm's Money Laundering Reporting Officer (MLRO). Failure to report is a criminal offence carrying up to 5 years' imprisonment.

The privilege exemption

Section 330(6) of POCA provides that the reporting obligation does not apply to information received in privileged circumstances. Information is received in privileged circumstances if it is communicated:

  • By a client (or their representative) in connection with the provision of legal advice, or
  • By a person seeking legal advice, or by a person in connection with legal proceedings

However, this exemption does not apply if the information is communicated with the intention of furthering a criminal purpose. This is known as the "crime/fraud exception" — if the client is seeking legal advice to facilitate money laundering, the privilege does not attach, and you must report.

In practice

If you form a genuine suspicion that your client is engaged in money laundering based on information received outside the scope of privileged communications (for example, through your own due diligence, source of funds checks, or observations about the transaction), you must submit a SAR. Where you are uncertain whether privilege applies, seek guidance from the firm's MLRO and, if necessary, from the SRA or the Law Society's practice advice service. Do not allow uncertainty about privilege to prevent you from reporting where you should.

Tipping off

Once a SAR has been submitted (or you know one has been submitted), it is a criminal offence under section 333A of POCA to disclose to the client or any third party that a report has been made, if that disclosure is likely to prejudice any investigation. The maximum penalty is 5 years' imprisonment. However, disclosure to another legal professional for the purpose of legal proceedings is not tipping off.

  1. 1. Appoint an MLRO with sufficient seniority

    Designate a Money Laundering Reporting Officer who has the seniority and authority to make decisions about reporting suspicious activity. In smaller firms this is often a partner or the COLP. Notify the SRA of the appointment. Ensure a deputy MLRO is appointed to cover absences.

  2. 2. Complete your firm-wide risk assessment

    Produce a written assessment of your firm's money laundering and terrorist financing risks covering all practice areas within MLR 2017 scope. Follow the LSAG guidance methodology. Ensure the assessment reflects your firm's actual work, not a generic template. Have it approved by the COLP or senior management.

  3. 3. Establish CDD policies and procedures

    Create documented procedures for client identification and verification, beneficial ownership identification, source of funds verification, source of wealth checks for high-risk clients, PEP screening, and ongoing monitoring. Procedures must cover both standard and enhanced due diligence and set out clear escalation routes.

  4. 4. Implement matter risk assessments

    Require a documented risk assessment for every client and matter within the scope of the MLR 2017. Use the risk assessment to determine the level of CDD required (simplified, standard, or enhanced). The SRA provides a template, but adapt it to your firm's practice areas.

  5. 5. Set up SAR procedures and train all staff

    Establish a clear internal process for staff to report suspicions to the MLRO. Provide initial AML training to all staff on joining and at least annually thereafter. Training must cover recognition of suspicious activity, the firm's reporting procedures, legal professional privilege boundaries, and the tipping off offence.

  6. 6. Establish record keeping and monitoring

    Set up systems to retain all CDD records, risk assessments, SARs, and training records for at least 5 years. Conduct regular compliance monitoring through file reviews and sample testing. Document your monitoring findings and any corrective actions.

  7. 7. Prepare for SRA supervisory engagement

    Ensure your firm-wide risk assessment, policies, procedures, training records, and compliance monitoring evidence are readily accessible. The SRA may conduct desk-based reviews, request specific documentation, or carry out on-site visits. Higher-risk firms should expect more frequent supervisory contact.

What happens next

AML compliance is not a one-off exercise. After implementing these measures, you must:

  • Review and update your firm-wide risk assessment at least annually, or when your practice areas, client base, or risk profile change materially
  • Refresh staff training at least annually, covering new typologies and any changes to your procedures
  • Conduct regular compliance monitoring through file reviews, testing whether CDD is being completed correctly and SARs are being filed appropriately
  • Respond promptly to any requests from the SRA, whether for documentation, information, or corrective action
  • Monitor updates from the SRA, NCA, and LSAG for changes to guidance, thematic findings, or emerging risks

ℹ️ Consent SARs and conveyancing completions

If you suspect the funds in a property transaction are the proceeds of crime, you must submit a SAR and request consent from the NCA before proceeding to completion. The NCA has 7 working days to respond. If consent is refused, a further 31-day moratorium applies. Proceeding without consent risks committing a principal money laundering offence under sections 327-329 of POCA 2002. Build this timeline into your completion schedule.
