Common Law vs Civil Law Trust Jurisdiction: What Changes for a Trust

The trust was born in English courts of equity, and most of the jurisdictions that regulate it by statute still sit in the common-law family. Yet a growing number of families place a trust under the supervision of a civil-law country such as Switzerland. The common law vs civil law trust jurisdiction question is therefore less about whether a trust can exist in a civil-law seat and more about how it is recognized, supervised and enforced there.

This page compares the two families of legal systems on the points that actually change the outcome. It is general information, not advice: the right answer depends on where the settlor lives, where the beneficiaries live, what the trust holds and which law governs the trust deed.

The short answer

A trust does not need a common-law seat to work. What a civil-law seat changes is the route by which the trust is accepted, not the basic idea of a trustee who holds assets for others.

• In a common-law seat, the trust is part of the domestic legal fabric. Courts, statutes and professional practice all assume it.
• In a civil-law seat, the trust is usually a foreign institution that the domestic system agrees to recognize, typically through an international treaty, and then fits into its own rules on property, obligations and supervision.

Neither route is superior in the abstract. They trade familiarity of case law against the stability and predictability of a codified system.

What stays the same in both systems

Whatever the seat, the core mechanics of a trust are carried by the trust deed and the governing law you choose, not by the legal tradition of the place where the trustee works. The same roles appear: the settlor who creates the structure, the trustee who administers it, the beneficiaries who benefit from it and, sometimes, a protector who oversees certain decisions.

It also helps to keep three notions apart, because civil-law and common-law practitioners often mix them up:

• the governing law of the trust, sometimes called its proper law;
• the seat, meaning where the trust is actually administered;
• the residence of the people involved, which drives most tax and succession questions.

Our guide to governing law versus seat of administration and the entry on the proper law of a trust set out how these can point to different countries, and why that is lawful and often deliberate.

What changes in a civil-law seat

Recognition instead of native creation

Civil-law systems generally have no domestic trust of their own. They deal with trusts through a recognition mechanism. For many countries that mechanism is the Hague Convention on the law applicable to trusts and on their recognition, concluded in 1985. Switzerland has built its framework around that Convention: under the Swiss financial institutions legislation (LEFin), a trustee is anyone who, on a professional basis, manages a separate estate or disposes of it for a beneficiary or for a defined purpose, on the basis of a trust deed within the meaning of that Convention.

Recognition is not automatic everywhere. How far it goes in a given country depends on whether it is a party to the Convention, on any reservations it made and on its own public-order rules. The map of Hague parties and the explainer on the Convention show how uneven this can be.

Property law and the divided ownership problem

In a common-law system, legal ownership and beneficial entitlement can be held by different people at the same time. A civil-law property regime traditionally prefers a single owner per asset. Recognition rules therefore treat the trust assets as a separate estate, kept apart from the personal assets of the trustee, and they rely on the Convention to avoid reclassifying the arrangement as something else.

The practical point for a settlor is not theoretical. It matters when a trustee becomes insolvent, when a creditor claims assets, or when the trust holds property located in a civil-law country. For that last case, see the page on holding real estate through a trust.

Courts, equity and discretion

Common-law courts have a long tradition of equitable remedies and of reviewing how a trustee used a discretion. Civil-law courts work from codes and from statute, with less room for judge-made doctrine. This usually means fewer surprises of the kind that arise from an evolving body of precedent, but also fewer ready-made answers where a trust deed is silent or unusual.

For cross-border disputes, the question of who hears the case and whose judgment travels is addressed in courts, enforcement and foreign judgments for trusts.

Regulation of the trustee

This is where a civil-law seat can differ most visibly from the lightly supervised common-law seats. In Switzerland, professional trustees are treated as financial institutions under the LEFin, in the same category as asset managers, fund management companies and securities firms. The main features, taken from the official sources, are:

• The FINMA grants the authorization. Day-to-day checking that the conditions are still met is done by a supervisory organization (organisme de surveillance), which is itself authorized and supervised by the FINMA, and changes in relevant facts must be reported to it in advance.
• A trustee based in Switzerland must be a sole proprietorship, a commercial company or a cooperative, entered in the commercial register.
• The minimum capital is CHF 100,000, paid in cash, together with appropriate guarantees or professional liability insurance.
• The management must include at least two qualified persons, with adequate training and sufficient professional experience.
• The trustee manages the separate estate, preserves its value and uses it in line with its purpose.

Supervision of this kind is a feature for some families and a constraint for others. Our comparison of regulated versus lightly regulated seats explores the trade-off in more detail. For the Swiss case specifically, see Switzerland as a trust seat.

Common-law and civil-law seats side by side

The table is a generalization. Each country in either family has its own statute, and some common-law seats look more codified than some civil-law ones.

Where each family tends to fit better

Neither approach wins in every case. A few patterns are worth knowing, always subject to individual analysis.

Situations that often point to a common-law seat

A settlor who wants a long tradition of case law on discretionary powers, a deep local market of trustees, or a statute with specific tools for protecting assets may lean that way. The asset-protection statutes compared page lays out how those statutes differ and where they have been tested.

Situations that often point to a civil-law seat

A family that values a codified system, a regulated trustee under a recognized supervisory authority, close access to private banking and custody, and a stable political environment may prefer a civil-law seat. This tends to matter more when the beneficiaries or the assets are themselves located in civil-law countries, because the trust then sits in a legal environment familiar to local authorities.

Example: a family established in Lausanne holds a business, a portfolio and a holiday home abroad. Its advisers consider a trust governed by a common-law statute but administered in Switzerland, so that the trustee is regulated, the banking is local and the governing law remains familiar to foreign courts. This is an illustration, not a recommendation.

Revocable and irrevocable trusts across the two families

The settlor's retained control is one of the points where legal tradition can show. Some civil-law authorities look closely at trusts where the settlor keeps broad powers, because they may question whether the assets have genuinely left the settlor's estate. Common-law seats vary: some accept reserved powers by statute, others police them through case law. How this plays out is covered in revocable and irrevocable trusts by legal system.

The same caution applies to forced heirship. A civil-law country may apply mandatory succession rules to assets or people connected with it, regardless of where the trust is seated. The page on forced heirship and trusts explains which seats offer more resistance to such claims, and which do not.

Questions to ask before choosing a family of systems

• Where do the settlor and the main beneficiaries live, and under which succession rules?
• Is the country where the assets sit a party to the Hague Convention?
• How much supervision of the trustee does the family actually want?
• Would a foundation or company serve the purpose better than a trust? See trust, foundation or company.
• Which courts would be asked to enforce decisions, and would they act?

A confidential assessment can turn these general questions into an analysis of your own facts.

Conclusion: selon votre situation

The comparison does not produce a universal winner. A common-law seat brings a native trust culture and a rich body of case law; a civil-law seat brings codification, formal supervision and a recognition framework that many families find reassuring. Which one fits depends on your situation, and the answer can change if you or your assets move.
