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, held by a trustee, from beneficial ownership, held by beneficiaries. It has no legal personality of its own. It is simply a set of obligations that beneficiaries can enforce. A foundation works differently. It is an orphan legal entity that owns its assets outright, in its own name. It has a council rather than a trustee, and its beneficiaries typically have weaker enforcement rights. Common law systems understand the first instinctively. Civil law systems, which generally do not recognize split ownership, understand the second.
• The Hague Convention of 1 July 1985 on the Law Applicable to Trusts and on their Recognition is what allows a trust to travel into civil law territory. Its reach, though, 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. That means a trust arriving in Madrid or Munich is being recognized, if at all, on general private international law principles rather than by treaty.
• The Convention does not harmonize 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 recognize the trust. It does not mean the trust wins.
• Forced heirship is the real battleground here, and it is not a technicality. Most civil law systems reserve fixed shares of an estate for children, and often the surviving spouse, regardless of what the will says. That reserved share is commonly half or more where there are several children. Offshore trust jurisdictions, including Jersey, Guernsey, Cayman, BVI, Bahamas, Cook Islands and Nevis, have enacted firewall provisions. These declare that the validity of transfers into the trust is governed by local law, and that foreign forced heirship judgments will not be enforced there. The firewall protects the assets held in that jurisdiction. It does very little for assets, or people, located in the forced heirship country itself.
• Foundations exist precisely to solve the recognition problem, and the mainstream vehicles differ in meaningful ways. 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 its jurisdiction. Jersey, Guernsey, Bahamas, Cayman, Nevis, Malta and the Netherlands, through its stichting, all offer statutory foundations. Several were designed explicitly for families who want an entity that a civil law court will recognise without any Hague analysis at all.
• The choice usually comes down to four questions, asked in order. First, where will the family actually live and die: in a common law country or a civil law one? Second, is forced heirship a live issue for this family? Third, how much control does the founder need to retain, and can the jurisdiction accommodate that through a reserved powers regime without the structure collapsing? Fourth, how will the vehicle be taxed by the countries where the beneficiaries will actually be resident. That last question is about the beneficiaries' future, not the settlor's present.
• Tax treatment on relocation is where good structures die. A trust that counts as fiscally transparent in one country can become an opaque, taxable entity in another. Several civil law systems, including France under art. 792-0 bis, Spain and Italy, apply look-through or penal deemed-income regimes to trusts precisely because they distrust them. A beneficiary who moves to a new country can trigger taxation of the whole structure there. For US persons, the analysis is separate and severe. It involves 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

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

Liechtenstein low

The Stiftung is a separate legal person. It requires CHF 30,000 minimum capital, sits within a mature statutory framework under the PGR, and benefits from courts experienced in family disputes. Liechtenstein has been a Hague Convention party since 1 April 2006, so it recognizes trusts as well as offering foundations. Formation and annual costs run higher than Panama, but the institutional support is materially better. Liechtenstein also offers a trust structure, a contractual arrangement without separate legal personality, for families who want the common law form inside a civil law jurisdiction.

Panama medium

Panama's private interest foundation has separate legal personality, a USD 10,000 capital requirement, and low running costs. It has been a Hague Trusts Convention party since 1 December 2018. The trade-off shows up in reputation 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 draws heavier scrutiny at every touchpoint.

Jersey / Guernsey / Cayman / BVI low

These are the core common law trust jurisdictions. Each has statutory firewall provisions that block foreign forced heirship claims and refuse enforcement of foreign judgments against the trust. Each also offers reserved powers regimes, letting a settlor keep defined powers without invalidating the trust. Jersey and Guernsey also offer statutory foundations. Cayman's STAR and BVI's VISTA regimes solve a specific problem: holding a family operating company in trust without forcing the trustee to diversify the holding or intervene in management.

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

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

United States (beneficiaries) high

A US-resident beneficiary changes the analysis entirely. There are foreign grantor and non-grantor trust rules to navigate. There is the throwback tax, which carries an interest charge on accumulated income distributions. There is PFIC look-through on underlying holdings. And there are Forms 3520 and 3520-A, with penalties starting at 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%.
