Trust Registration Service
The Trust Registration Service is HMRC's central register of UK express trusts, mandated under MLR 2017 Regulation 45ZA. Almost all UK express trusts must be registered on the TRS, regardless of whether they generate a tax liability, with named trustees, settlors, and beneficiaries (or class of beneficiaries) disclosed. Failure to register attracts HMRC penalties.
solicitors involved in trust formation, administration, or amendment should treat TRS registration as part of routine compliance — and as a CDD source. The TRS record can be cross-checked against the firm's independent beneficial-ownership findings on the trust; mismatches should be investigated before acting.

An express trust is a trust deliberately created by a settlor — by deed, will, or written declaration — naming trustees and identifying beneficiaries or a class of beneficiaries. Express trusts are distinguished from implied or constructive trusts (which arise by operation of law). Almost all UK express trusts must be registered on the HMRC Trust Registration Service under MLR 2017.
A beneficial owner is the natural person who ultimately owns or controls a legal entity — such as a company or trust — or on whose behalf a transaction is being conducted. Identifying beneficial ownership is a core CDD obligation where clients are companies, partnerships, or trusts, since the legal owner and the true controlling person may be different.
A Trust or Company Service Provider is a business that — by way of a business — forms companies, provides registered-office or business-address services, acts as or arranges for nominee shareholders or directors, or acts as or arranges for trustees of express trusts. TCSPs are within scope of MLR 2017 (Regulation 12) and must be either supervised by HMRC or a relevant professional body.
Before you treat Trust Registration Service as handled
- Confirm which regulation, policy, or internal procedure the term maps to.
- Document the decision or evidence trail in the client file, not only in email or chat.
- Escalate where the term indicates higher risk, sanctions exposure, PEP status, suspicion, or missing evidence.
- Keep the wording consistent across onboarding, review notes, training material, and inspection packs.
