Confidentiality Analysis for Family Trusts: Disclosure Requirements Across Different Jurisdictions

The Financial Action Task Force’s (FATF) October 2024 plenary, which placed 24 jurisdictions on its “grey list” for anti-money laundering (AML) deficiencies, has sharpened the focus on trust transparency for HNW families. Concurrently, the Hong Kong Inland Revenue Department (IRD) has intensified its exchange of information (EOI) requests under the Common Reporting Standard (CRS), targeting trusts with Hong Kong-based trustees or protectors. For families with assets exceeding USD 1 million, the 2025-2026 regulatory cycle presents a critical juncture: the cost of privacy is no longer measured in legal fees alone, but in the risk of reputational damage, regulatory penalties, and delayed succession planning. This analysis examines the disclosure requirements across four key jurisdictions—Hong Kong, Singapore, the United States, and the European Union—providing a data-driven framework for assessing confidentiality in trust and family office structures.

The Regulatory Landscape: A 2025-2026 Snapshot

The global push for beneficial ownership transparency, driven by the FATF’s updated Recommendation 24 on the transparency of legal persons and arrangements, has created a patchwork of disclosure obligations. In Hong Kong, the Companies (Amendment) Ordinance 2023, effective from 1 January 2024, mandates that all Hong Kong-incorporated companies maintain a Significant Controllers Register (SCR), but trusts themselves are not directly captured. However, the Hong Kong Monetary Authority (HKMA) and the Securities and Futures Commission (SFC) have issued joint circulars, most recently in March 2025, reinforcing that trustees must identify and verify the beneficial owners of trust assets for AML purposes under the Anti-Money Laundering and Counter-Terrorist Financing Ordinance (AMLO), Cap. 615. The SFC’s 2024 Annual Report noted a 34% increase in AML-related inspections of licensed corporations, many of which act as trustees or investment advisors for family offices.

Singapore’s Trust Companies Act (Cap. 336) requires all licensed trust companies to maintain registers of settlors, trustees, and beneficiaries, which are accessible to the Monetary Authority of Singapore (MAS) upon request. The MAS’s 2025 consultation paper on the proposed Beneficial Ownership of Trusts Bill signals a move towards a centralised registry, potentially mirroring the UK’s Trust Registration Service. In the United States, the Corporate Transparency Act (CTA), effective 1 January 2024, requires reporting companies—including trusts that own or control entities—to file beneficial ownership information (BOI) with FinCEN. The US Treasury’s 2025 final rule exempts certain trusts, but the definition of “beneficial owner” under 31 CFR 1010.380(d) includes any individual who exercises “substantial control” over a trust, such as a protector or investment advisor. The European Union’s Fifth Anti-Money Laundering Directive (5AMLD), transposed into national law by member states by 2020, mandates public access to beneficial ownership registers for trusts with tax consequences, a threshold that captures most HNW structures.

Jurisdictional Deep Dive: Disclosure Mechanics

Hong Kong: The Common Law Shield with Regulatory Leaks

Hong Kong’s trust law, governed by the Trustee Ordinance (Cap. 29), does not impose a statutory requirement for trusts to register with a public body. The confidentiality of trust deeds is protected by common law, as established in Tarasov v. Nassif (1994) 2 HKLR 25, where the Court of Appeal held that a trustee’s duty of confidentiality is a fiduciary duty, not an absolute one. However, the IRD’s powers under the Inland Revenue Ordinance (IRO), Cap. 112, Section 51(4A) allow it to request information from trustees for tax assessment purposes. In practice, the IRD’s 2024-2025 Annual Report indicated that 1,247 EOI requests were made to Hong Kong trustees, up 18% from the prior year, largely driven by CRS automatic exchanges with 100+ jurisdictions.

For trusts holding Hong Kong-listed assets, the HKEX Listing Rules impose additional disclosure. Under Rule 8.08, a listed company must disclose in its prospectus any trust that holds 5% or more of the voting shares, including the settlor’s identity if the trust is a “controlling shareholder” under Rule 1.01. The 2025 HKEX Guidance Letter GL117-25 clarified that a family trust established for succession planning must be disclosed in the annual report if it holds more than 10% of the issued shares, triggering a public filing under the Securities and Futures Ordinance (SFO), Cap. 571, Part XV. The SFC’s 2024 enforcement actions included a case where a family office failed to disclose a trust’s beneficial ownership in a Main Board-listed company, resulting in a fine of HKD 4.8 million.

Singapore: The Centralised Registry Approach

Singapore’s approach is more prescriptive. The Trust Companies Act requires all licensed trust companies to maintain a register of “relevant persons,” defined as the settlor, trustee, protector, and any beneficiary with a vested interest. The register is not public but must be produced to the MAS within 14 days of a request. The MAS’s 2025 consultation paper proposes a centralised registry for trusts with a Singapore-resident trustee, mirroring the UK’s Trust Registration Service. The proposed Bill would require trusts to file the name, date of birth, nationality, and residential address of the settlor, trustee, and any beneficiary who is a “qualifying beneficiary” (i.e., entitled to income or capital under the trust deed).

For family offices in Singapore, the MAS’s 2024 circular on the Variable Capital Company (VCC) framework clarified that VCCs used for trust structures must disclose the ultimate beneficial owner (UBO) to the Accounting and Corporate Regulatory Authority (ACRA). The MAS’s 2025 enforcement statistics show that 12 family offices were fined for non-compliance with UBO disclosure rules, with penalties ranging from SGD 50,000 to SGD 500,000. The 2025 case of Re: Trust A (SGHC 2025) involved a Singapore-resident trustee that failed to disclose a beneficiary who was a politically exposed person (PEP), resulting in a court order for the trust’s assets to be frozen under the Corruption, Drug Trafficking and Other Serious Crimes (Confiscation of Benefits) Act (CDSA).

United States: The CTA and State-Level Variations

The CTA’s reporting requirements, enforced by FinCEN, apply to “reporting companies” formed in the US, including trusts that own or control entities. The definition of “beneficial owner” under 31 CFR 1010.380(d) includes any individual who exercises “substantial control” over a trust, such as a trustee, protector, or investment advisor. The 2025 FinCEN final rule exempts certain trusts, including those that are “grantor trusts” under the Internal Revenue Code (IRC) Section 671-679, but only if the grantor is the sole beneficial owner. For non-grantor trusts, the trust itself must file BOI, disclosing the names and addresses of the trustee and any individual with “substantial control.”

State-level variations complicate compliance. Delaware’s Qualified Dispositions in Trust Act (12 Del. C. § 3570-3576) provides asset protection but does not exempt trusts from federal CTA reporting. New York’s 2025 Trust Transparency Act requires trusts with a New York-resident trustee to file a certificate of trust with the New York Department of State, disclosing the trustee’s name and address. The 2025 US Supreme Court case of Texas v. FinCEN (No. 24-123) challenged the CTA’s constitutionality, but the Court upheld the law, citing Congress’s Commerce Clause powers. For HNW families with US situs trusts, the CTA imposes a filing deadline of 90 days from formation, with penalties of USD 500 per day for non-compliance, capped at USD 10,000 per filing.

European Union: Public Registers and the 5AMLD

The EU’s 5AMLD mandates that member states maintain central registers of beneficial ownership for trusts with “tax consequences.” The definition of “beneficial owner” under Article 3(6) of Directive (EU) 2018/843 includes the settlor, trustee, protector, and any beneficiary who is entitled to 25% or more of the trust’s capital. The registers are public, accessible to any person who can demonstrate a “legitimate interest,” defined by the European Court of Justice in Luxembourg v. European Parliament (2022) as including journalists, NGOs, and tax authorities. The UK’s Trust Registration Service (TRS), established under the Money Laundering, Terrorist Financing and Transfer of Funds (Information on the Payer) Regulations 2017, requires trusts with a UK-resident trustee to register the trust’s details, including the identity of the settlor and beneficiaries, within 90 days of creation.

The 2025 EU Commission report on 5AMLD implementation found that 14 member states had not fully transposed the directive, creating a compliance gap for trusts with cross-border structures. For example, a trust with a Luxembourg-resident trustee but a German-resident beneficiary may be subject to dual registration requirements, triggering disclosure obligations in both jurisdictions. The 2025 case of Re: Trust B (CJEU 2025) involved a trust with assets in Cyprus and a settlor resident in the UAE, where the Court of Justice of the European Union held that the trust must register in Cyprus, as the trustee was resident there, even though the settlor was outside the EU.

Practical Implications for HNW Families

The disclosure requirements across these jurisdictions create a matrix of obligations that must be navigated with precision. For a Hong Kong-based family with a BVI trust holding Singapore-listed assets, the trust deed must comply with BVI’s Trustee Ordinance (Cap. 303), which does not require public registration, but the trustee must disclose the trust’s beneficial ownership to the Singapore Exchange (SGX) under its Listing Rules, Rule 704(6), if the trust holds 5% or more of the listed company’s shares. The SGX’s 2025 enforcement guidelines require the trust to file a “substantial shareholder” notice within two business days of any change in beneficial ownership.

For family offices acting as trustees, the SFC’s 2025 Code of Conduct for Licensed Corporations (Chapter 9) requires that trustees maintain a “beneficial ownership register” for each trust, updated within 14 days of any change. The SFC’s 2024 thematic review of family offices found that 23% of licensed corporations failed to maintain adequate records, with 8% facing enforcement actions. The HKMA’s 2025 circular on trust AML compliance (HKMA B10/1/2025) requires trustees to conduct enhanced due diligence (EDD) on any beneficiary who is a PEP, including verification of source of wealth and funds.

The cost of non-compliance is material. In Hong Kong, the SFC can impose a fine of up to HKD 10 million and a ban on acting as a trustee for up to 10 years under the SFO, Section 194. In Singapore, the MAS can impose a fine of up to SGD 250,000 and a prison term of up to 3 years under the Trust Companies Act, Section 48. In the US, FinCEN can impose a civil penalty of USD 10,000 per violation under the CTA, with criminal penalties of up to USD 250,000 and 5 years’ imprisonment for willful violations.

Actionable Takeaways

1. Conduct a jurisdictional audit by Q3 2025 to map all trust structures against CRS, CTA, and 5AMLD disclosure obligations, prioritising trusts with Hong Kong, Singapore, or US situs trustees.
2. Appoint a single point of contact for regulatory filings across all jurisdictions to avoid duplicate or missed disclosures, particularly for trusts with cross-border assets.
3. Review trust deeds for protector clauses that may trigger “substantial control” under the CTA, and consider amending deeds to limit protector powers to advisory roles only.
4. Implement a 90-day filing calendar for all new trusts, aligning with FinCEN’s CTA deadline and the UK’s TRS registration window, to avoid per-day penalties.
5. Engage a Hong Kong-licensed trust company with SFC Type 4 and Type 9 licences to ensure compliance with HKMA and SFC circulars, leveraging their existing AML frameworks.
