Legal & TCSPs

The statutory perimeter for legal professionals and trust or company service providers, with explanations of ownership checks, client money and reporting exceptions.

Independent regulatory guidanceSources reviewed: 16 October 2026UK jurisdiction
01 · Legal perimeter

Scope and supervision

Responsible supervisor

The relevant legal professional-body supervisor, or HMRC for TCSP activity not supervised by the FCA or an eligible professional body.

Regulation 12 covers independent legal professionals participating in specified financial or real-property transactions, including property or business sales, managing client assets, opening or managing accounts, organising company contributions and creating or managing trusts or companies.

TCSP activities include forming companies, providing specified officers or business addresses, acting as trustee of an express trust, or acting as nominee shareholder, by way of business. Assess each service and the appropriate supervisor before trading.

Not all legal work falls within the MLR perimeter. Litigation and legal advice require a careful activity-level analysis. Being outside the MLR does not remove the principal POCA offences or UK sanctions obligations. LSAG guidance explains the legal-sector application of the law.

02 · Sector requirements

Rules specific to this sector

An instruction is not automatically in scope just because the provider is a lawyer. Conversely, describing company-formation or trust services as administration does not remove them from the perimeter. Regulation 12 defines the covered services.

Where HMRC registration is required, the registration framework in Regulations 54–59 applies. Firms supervised by a qualifying professional body must establish which activities that supervision covers, rather than assume every TCSP service is exempt from separate registration.

Practical application

Record a scope decision for service lines and unusual instructions, and confirm supervision and any required approvals before providing regulated services.

03 · Regulatory framework

Core regulations explained

These duties apply where the business and activity fall within the relevant statutory scope. Sector-specific provisions, exceptions and proportionality conditions must be considered alongside each explanation.

Regulation 18 requires a relevant person to identify and assess its money-laundering and terrorist-financing risks. The assessment must consider customers, countries or geographical areas, products or services, transactions and delivery channels, as well as information made available by the supervisory authority. Its extent must be appropriate to the size and nature of the business.

Keep a written record and keep the assessment up to date unless the supervisor has determined that an individual documented assessment is unnecessary for the sector. Regulation 18A separately addresses proliferation-financing risk: the risk of breaches, non-implementation or evasion of financial sanctions connected with proliferation of weapons of mass destruction.

Practical application

Record the evidence behind each risk rating, the controls used to reduce the risk and the remaining exposure. Reconsider the assessment when the business model, customer base or relevant threats change.
