Trusts vs foundations: the cross-border family's structural choice

What is actually true

• The conceptual difference is not cosmetic. A trust splits legal ownership (trustee) from beneficial ownership (beneficiaries) — it has no legal personality and is a set of obligations enforceable by beneficiaries. A foundation is an orphan legal entity that owns its assets outright in its own name, with a council rather than a trustee, and beneficiaries who typically have weaker enforcement rights. Common law systems understand the first natively; civil law systems, which generally do not admit split ownership, understand the second.
• The Hague Convention of 1 July 1985 on the Law Applicable to Trusts and on their Recognition is what makes a trust portable into civil law — and its reach is narrower than most people assume. It has just 14 Contracting Parties: Australia, Canada, China (for Hong Kong SAR), Cyprus, Italy, Liechtenstein, Luxembourg, Malta, Monaco, the Netherlands, Panama, San Marino, Switzerland and the United Kingdom. The United States and France signed it but never ratified. Germany, Spain, Austria, Belgium, Portugal and the Nordics are not parties at all — so a trust arriving in Madrid or Munich is being recognised, if at all, on general private international law principles rather than by treaty.
• The Convention does not harmonise trust law and does not override mandatory local rules. Article 15 expressly preserves the forum's mandatory provisions, including forced heirship, matrimonial property and creditor protection. Ratification means a civil law court will not simply refuse to see the trust — it does not mean the trust wins.
• Forced heirship is the real battleground and it is not a technicality. Most civil law systems reserve fixed shares of an estate for children and often the surviving spouse — commonly half or more where there are several children — regardless of the will. Offshore trust jurisdictions (Jersey, Guernsey, Cayman, BVI, Bahamas, Cook Islands, Nevis) have enacted firewall provisions declaring that the validity of transfers into the trust is governed by local law and that foreign forced heirship judgments will not be enforced. The firewall protects the assets held IN that jurisdiction; it does very little about assets, or people, located in the forced heirship country.
• Foundations exist precisely to solve the recognition problem, and the mainstream vehicles differ meaningfully. Liechtenstein's Stiftung is the oldest and most institutionally supported, with a CHF 30,000 minimum capital, a well-developed body of law and courts that understand it. Panama's private interest foundation requires USD 10,000, costs materially less to run, and carries the reputational profile of the jurisdiction. Jersey, Guernsey, Bahamas, Cayman, Nevis, Malta and the Netherlands (the stichting) all offer statutory foundations, several designed explicitly for families who want an entity that a civil law court will recognise without any Hague analysis at all.
• The choice usually turns on four questions, in order. Where will the family actually live and die — common law or civil law? Is forced heirship live for this family? How much control does the founder need to retain, and can the jurisdiction accommodate it via a reserved powers regime without collapsing the structure? And how will the vehicle be taxed by the countries where the beneficiaries will actually be resident — which is a question about the beneficiaries' future, not the settlor's present.
• Tax treatment on relocation is where good structures die. A trust that is fiscally transparent in one country may be an opaque taxable entity in another; several civil law systems (France's art. 792-0 bis, Spain, Italy) apply look-through or penal deemed-income regimes to trusts precisely because they distrust them; and a beneficiary moving to a new country can trigger taxation of the whole structure there. For US persons the analysis is separate and severe: foreign grantor and non-grantor trust rules, the throwback tax with its interest charge on accumulated income, and Forms 3520 and 3520-A with penalties starting at 35% of the amount involved.

Jurisdiction by jurisdiction

Hague Trusts Convention 1985 medium

14 Contracting Parties: Australia, Canada, China (Hong Kong SAR), Cyprus, Italy, Liechtenstein, Luxembourg, Malta, Monaco, Netherlands, Panama, San Marino, Switzerland, United Kingdom. The US and France signed but never ratified. Germany, Spain, Austria, Belgium, Portugal and the Nordics are not parties. Article 15 preserves the forum's mandatory rules including forced heirship — recognition is not immunity.

Liechtenstein low

The Stiftung: a separate legal person, CHF 30,000 minimum capital, mature statutory framework under the PGR, courts experienced in family disputes, and Hague Convention party since 1 April 2006 (so it recognises trusts as well as offering foundations). Higher formation and annual cost than Panama, and materially better institutional support. Also offers a Liechtenstein trust — a contractual arrangement without separate personality — for families who want the common law form in a civil law jurisdiction.

Panama medium

Private interest foundation: separate legal personality, USD 10,000 capital requirement, low running cost, and Hague Trusts Convention party since 1 December 2018. The trade-off is reputational and banking: opening and maintaining institutional accounts for a Panamanian foundation is harder and slower than for a Liechtenstein or Jersey vehicle, and the structure attracts enhanced scrutiny at every touchpoint.

Jersey / Guernsey / Cayman / BVI low

The core common law trust jurisdictions, all with statutory firewall provisions excluding foreign forced heirship claims and refusing enforcement of foreign judgments against the trust, and all offering reserved powers regimes allowing a settlor to retain defined powers without invalidating the trust. Jersey and Guernsey also offer statutory foundations. Cayman's STAR and BVI's VISTA regimes solve the specific problem of holding a family operating company in trust without the trustee being obliged to diversify or intervene.

Civil law forced heirship states (France, Spain, Italy, Germany, Belgium) high

Reserved shares for children — commonly half or more of the estate where there are multiple children — override testamentary freedom and can be enforced against assets located in the jurisdiction regardless of any trust or foundation. France additionally applies a penal deemed-income and reporting regime to trusts (art. 792-0 bis CGI). The EU Succession Regulation (650/2012) allows a choice of the law of nationality for succession, which is the principal planning tool here — but it does not bind non-participating states and does not displace tax.

United States (beneficiaries) high

A US-resident beneficiary transforms the analysis. Foreign grantor/non-grantor trust rules, the throwback tax with an interest charge on accumulated income distributions, PFIC look-through on underlying holdings, and Forms 3520/3520-A with penalties from 35% of the amount involved. If a covered expatriate is in the picture, §877A(f) imposes 30% withholding on non-grantor trust distributions and §2801 taxes US recipients at 40%.
