Trust Litigation Jurisdiction: Which Courts Hear Disputes and Enforce Judgments

Trust litigation jurisdiction is the question of which courts have the power to hear a dispute about a trust, and, just as important, whether the resulting judgment can be put into effect where the assets, the trustee or the beneficiaries are located. Most people choose a trust seat by looking at tax, privacy and banking. Few ask the plainer question: if something goes wrong in ten or twenty years, who decides, and who can make the decision stick? The answer depends on the courts of the seat, the clauses in the trust deed, and the willingness of other countries to honor a foreign ruling.

This guide explains the dispute path from the first filing to the last enforcement step, and then draws out what that path means when you compare Switzerland with the other trust jurisdictions. It is general information, not advice on a specific structure. The outcome in a real case depends on where the settlor lives, where the beneficiaries live, what the assets are and which law governs the trust.

Why courts matter more than statutes when choosing a seat

Trust statutes attract attention because they are easy to compare: a list of permitted features, a duration limit, a rule on reserved powers. Courts are harder to compare, yet they are where a trust is tested. A well drafted deed in a jurisdiction with a strong statute can still fail its beneficiaries if the local court is slow, unfamiliar with trusts or unwilling to supervise a trustee.

Two separate capacities are involved, and they are easy to confuse:

• Adjudicative capacity: a court with jurisdiction hears the claim, applies the governing law and issues a ruling. This is the forum question.
• Enforcement capacity: a court, usually in another country, recognizes that ruling and lets bailiffs, registries or banks act on it. This is the enforcement question.

A claimant may win in the first and lose in the second. A beneficiary who obtains an order removing a trustee in one country may find that a bank in another country will not release assets on that order alone. Conversely, a trustee who is protected by a strict local statute may find that a court elsewhere simply does not apply it. For that reason, a sound seat review looks at both capacities, and also at the places where assets sit, as discussed in the page on governing law versus seat.

The kinds of disputes that reach a court

Trust disputes fall into recognizable families. Each family tends to land in a different forum, and each raises a different enforcement problem.

The table is a simplification. In practice the same facts can generate several of these disputes at once, in several countries, which is why forum planning belongs in the original structuring conversation and not only in a crisis.

The path of a dispute: from forum to enforcement

The diagram below follows a typical contested case. Not every dispute passes through every step; many end after the first or second.

Three observations follow from this path. First, the deed controls the earliest steps and is the cheapest place to prevent trouble. Second, the middle steps are where mandatory rules, such as those protecting heirs, can change the result. Third, the final steps are where seat choice pays off or fails: a ruling from a respected court travels more easily than one from a court whose procedures other countries distrust.

Jurisdiction and forum clauses in the trust deed

Many trust deeds contain a clause stating that the courts of the seat have exclusive or non-exclusive jurisdiction over disputes about the trust. The clause is useful, but it has limits that settlors often overlook.

Exclusive and non-exclusive clauses. An exclusive clause sends all disputes to one court. A non-exclusive clause allows that court to act while leaving other courts free to hear related claims. Which to choose depends on how many countries are involved and on how much the family fears parallel proceedings.

Who is bound. A forum clause binds those who accept the trust. A trustee who signs the deed is bound. A beneficiary who claims a benefit is normally treated as accepting the deed's terms. A creditor, a spouse or an heir who attacks the trust as invalid does not accept anything, and a court elsewhere may refuse to be bound by the clause. In other words, the clause governs internal disputes better than external ones.

Arbitration. Some deeds send disputes to arbitration. This can bring confidentiality and expert decision makers, and arbitral awards generally circulate more easily across borders than court judgments because of the New York Convention. The difficulty is that some matters, such as the validity of a trust against third-party claims or the protection of vulnerable beneficiaries, are not always treated as arbitrable. Courts of some seats also keep supervisory powers that cannot be excluded. Whether arbitration helps therefore depends on the seat and on the type of dispute.

Mediation and protector steps. A deed can require the parties to consult a protector or to attempt mediation before a claim is filed. This can calm a family dispute, yet it should be drafted carefully so that it does not delay urgent applications such as freezing orders. The powers of a protector, and the way the law of each seat treats them, are covered in the page on protector and reserved powers law by jurisdiction.

Recognition and enforcement of foreign judgments

Recognition and enforcement are related but not identical. Recognition means a court accepts that a foreign judgment has settled a point, so that the matter cannot be argued again. Enforcement means that the court goes further and lends its machinery to carry out the judgment. A declaration that a trust is valid needs recognition; an order to pay money needs enforcement.

Three broad families of rules decide whether a foreign judgment is honored.

Treaties and conventions

Some groups of countries have agreed to recognize each other's judgments. Within Europe, the Lugano Convention links the European Union, Switzerland, Norway and Iceland on civil and commercial matters. Its scope has exclusions, however, and the status of trust claims under such instruments has been debated for years. At global level, the Hague Judgments Convention has been created to ease cross-border recognition, but it applies only between states that have joined, and it has its own exclusions. Neither instrument should be assumed to cover a given trust dispute without a check by counsel.

It helps to remember what the Hague Trusts Convention does and does not do. It is concerned with the law applicable to trusts and with their recognition as a legal institution. It does not create a system of courts, and it does not itself provide for enforcing judgments. The page on the Hague Trusts Convention explained sets out its reach.

Statutory registration regimes

Many common-law countries have statutes that let a judgment creditor register a money judgment from certain other countries, with limited defenses. These regimes are often reciprocal and often limited to final money judgments. They are less helpful for non-monetary orders, such as an instruction to account, to restore assets or to step down as trustee.

Common-law actions and national private international law

Where no treaty or statute applies, a creditor typically has to sue on the foreign judgment as a debt, or apply under the private international law of the enforcing country. Courts will usually check four things: that the original court had a proper basis for jurisdiction, that the defendant had a fair chance to be heard, that the judgment is final and that recognizing it would not offend public policy. They generally do not reopen the merits.

Public policy is where trust cases are most exposed. A judgment that sets aside a trust on a ground the enforcing country considers contrary to its own fundamental rules, or that disregards a protective statute, may be refused. The reverse also holds: a judgment confirming a trust may be refused by a court that regards the structure as an attempt to evade mandatory rules.

Where Switzerland fits

Switzerland is an interesting case because it does not have its own domestic trust law, yet it recognizes foreign trusts and provides rules on how they are treated. Trusts fall under Article 149c of the Federal Act on Private International Law (PILA, or LDIP in French), which refers to the Hague Trusts Convention for the applicable law. Article 15 of that Convention keeps mandatory rules on succession rights in place, so a trust cannot be used to remove what the applicable inheritance law protects.

For disputes, the practical result is this. Swiss courts can and do deal with foreign trusts, for example where a trustee is established in Switzerland, where assets are held in a Swiss bank or where a party lives in Switzerland. Swiss private international law contains specific provisions on trust jurisdiction and on recognizing foreign decisions, and the Lugano Convention applies to judgments coming from the states bound by it. What a Swiss court will not do is apply a Swiss trust statute, because none exists in the form of a standalone trust law.

That last point has a history worth knowing. A parliamentary motion, number 18.3383, filed on 26 April 2018, asked the Federal Council to create the legal basis for a Swiss-law trust. The Federal Council opened a consultation on an amendment to the Code of Obligations on 12 January 2022. On 15 September 2023, it noted the results, found no sufficient political consensus, observed that the proposed tax rules had been clearly rejected, decided not to prepare a dispatch and proposed that Parliament write off the motion. The motion is now recorded as closed.

The consequence for litigation is that a trust administered in Switzerland usually has a foreign governing law, often that of a common-law jurisdiction, while the trustee, the bank and the day-to-day administration sit in Switzerland. Disputes may then involve two courts: the court of the governing law, which interprets the deed, and Swiss courts, which deal with the trustee and the assets locally. Families who like the stability of Swiss institutions should know that this dual structure is normal and plan for it. For the broader picture of strengths and limits, see Switzerland as a trust seat.

Mandatory rules, forced heirship and the limits of the forum

Many trust disputes are really inheritance disputes in disguise. A child who was left less than the share protected by the law of the deceased's last residence may go to court in that country, not in the trust's seat, and argue that the transfer into the trust should be reduced or set aside.

Swiss succession law offers a useful reference. The revision of the Civil Code on succession came into force on 1 January 2023. Under Article 471 of the Civil Code, the reserved share is half of the statutory entitlement. Under Article 470, paragraph 1, the reserve concerns a person who leaves descendants, a spouse or a registered partner; parents are no longer among the protected heirs. The Federal Office of Justice presents the reform as a way to let people dispose freely of a larger part of their estate. In addition, an amendment to the PILA on international successions takes effect on 1 January 2025, according to the Federal Council's decision of 26 June 2024.

Such rules matter for forum choice because they show how mandatory law can travel with the heir rather than with the trust. A court of the seat may be willing to uphold the trust as written, while a court of the deceased's residence applies its own protective regime and orders adjustment against assets in its reach. Whether the first ruling can block the second depends on the countries concerned. The page on forced heirship and trusts compares seats on this point; here it is enough to say that a favorable ruling from the seat does not neutralize a claim brought elsewhere.

Example: a family established in Lausanne creates a trust with a trustee abroad and later one child, who lives in another country, claims a compulsory share. The child may sue where the parent lived or where the assets are, not necessarily where the trust is seated. A lawyer reviewing the structure would want to know, before any filing, which court has the strongest link to the assets and which courts would honor each other's rulings. This is an illustration, not a prediction.

Protective statutes and how courts respond to them

Some seats have legislated to shield trusts from foreign claims. These statutes may refuse to recognize foreign judgments based on forced heirship, limit the time within which creditors can challenge a transfer or require the challenger to prove intent. Some also include a clause that moves the trust automatically to another seat when it is threatened. The comparison of such rules is in the page on asset-protection statutes compared, and the term is defined in the entry on firewall legislation.

The limits are straightforward. A protective statute binds the courts of the seat that enacted it. It does not bind the courts of the settlor's home country, nor the courts where assets sit if they are elsewhere. If a creditor or heir has a judgment from a court with a strong link to the assets, and the assets are within that court's reach, the statute of the seat offers little help. Settlors sometimes overestimate what a statute can do; it is better described as a protection that has limits than as a shield.

Common-law seats and civil-law seats in court

Courts in common-law seats tend to have long experience with trusts. Their judges are used to supervising trustees, construing deeds and granting discretionary relief such as approving a trustee's decision. Several of these seats have specialist chambers. Civil-law seats, by contrast, often treat the trust as a foreign institution and handle disputes through general civil procedure or through the rules on foundations and mandates. The difference is described in more detail in the page on common-law seats versus civil-law seats.

Neither model is better in the abstract. A common-law court can offer predictability on trust questions, while a civil-law court can offer proximity to bank accounts, land registries and enforcement officers. The point is to match the court to the problem. A family whose assets are mostly in one civil-law country may care more about that country's enforcement tools than about the trust expertise of a faraway court.

Practical consequences for seat choice

The table below turns the discussion into questions that a seat comparison should answer. It is qualitative on purpose.

Reading across the list, the most reliable approach is to pair a seat whose courts are trusted internationally with assets located in places that will recognize its rulings. Where that pairing is weak, for example a trust in a lightly regulated seat that holds property and bank accounts in a country that distrusts such seats, the family carries a hidden enforcement risk. The risk grows if the seat is on a list of concern, a topic treated in the page on sanctions, blacklists and reputation risk.

What to do with an existing trust

If you already have a trust, a short review often reveals whether the forum and enforcement path is sound. Useful starting points are:

• Locate the forum clause in the deed and note whether it is exclusive.
• List the countries where the trustee, the beneficiaries, the settlor and the main assets are found.
• Identify which of those countries has a mandatory inheritance, matrimonial or creditor regime that could reach the trust.
• Find out whether judgments of the seat have been recognized in those countries in comparable cases.
• Check whether the deed provides a way to change the trustee or the seat if the courts become unreliable.
• Ask whether bank and custody arrangements would follow a court order from the seat or require a local one.

The answers do not give a verdict. They show where an individual analysis is needed. Trusts that were set up decades ago may sit in a seat whose courts or recognition prospects have changed, and the rules on moving a trust vary by jurisdiction.
