Fixed Interest Trust Jurisdiction: Where These Trusts Sit Best

Choosing a fixed interest trust jurisdiction is a different exercise from siting a discretionary arrangement. In a fixed trust the deed names who receives what, and when. That certainty is the point of the structure, and it means the seat you pick has to respect those entitlements in practice: before a court, on a register and in front of a tax authority.

This page explains how fixed entitlements are treated in different seats, where such trusts tend to sit comfortably, and what a confidential assessment can establish for your own case. It is general information, not advice on your situation.

What a fixed interest trust is, and what the service covers

In a fixed trust, each beneficiary holds a defined entitlement written into the trust deed: a share of capital, income, or both, with rules on timing and amount. The trustee administers the assets and follows the deed rather than exercising wide discretion over who benefits.

The service looks at families who want certainty over who receives what. Typical work includes:

• reviewing how entitlements are drafted so they are enforceable under the law that governs the trust;
• setting out clear rules on timing and amount of payments;
• confirming the beneficiaries' right to receive information about the trust;
• checking that administration can follow the deed in a straightforward way;
• testing whether the structure suits equal sharing among heirs.

It does not cover choosing or replacing a trustee, nor a general introduction to Swiss trusts. Fees depend on the structure and are indicated after the confidential assessment.

How the structure fits together

Four layers matter: the settlor who funds the trust, the trustee who holds title, the beneficiaries with their fixed shares, and the governing law that gives those shares their legal force.

The upper layer is easy to overlook. The governing law and the seat of administration may differ, and each answers different questions: the first decides what a beneficiary can claim, the second where the trust is run and reported.

How courts treat fixed entitlements

Common-law seats such as Jersey, Guernsey or the Cayman Islands treat a fixed beneficiary as holding an equitable interest that a court can enforce against the trustee. Their case law on trustee duties is long and predictable. Our comparison of Switzerland and Jersey shows how this works in practice.

Switzerland is a civil-law country with no trust statute of its own. It recognizes foreign-law trusts through the Hague Trusts Convention. Under Article 2 of the Convention, a trust is a legal relationship in which assets are placed under a trustee's control for a beneficiary or for a specific purpose. The assets form a separate fund, title is in the trustee's name, and the trustee must manage and account for them. Reserved powers kept by the settlor are not incompatible with a trust. For the wider picture, read Switzerland as a trust seat and the recognition map.

For a fixed trust, the practical consequence is that the entitlement is only as strong as the law chosen to govern the deed and the court willing to apply it. A Swiss trustee can administer a trust under a foreign governing law, and a court is then asked to apply that law to the fixed shares.

How registers and reporting see a fixed trust

Fixed entitlements make the beneficiaries identifiable by definition, so a fixed trust is the easiest type to report. Swiss anti-money-laundering rules treat trustees as financial intermediaries. Under Article 4 of the AMLA, the intermediary must identify the beneficial owner with due diligence and verify identity, and must obtain a written declaration where the contracting party is not the beneficial owner or in case of doubt.

On transparency, the new law on legal entities took effect with the transparency register, run by the Federal Office of Justice, starting on 1 October 2026. The official announcement speaks of legal entities and does not mention trusts, so do not assume that a Swiss register will list your trust. Other seats keep their own trust registers, which is why trust registers and privacy differ so much from one seat to the next.

Tax treatment of an irrevocable fixed interest trust in Switzerland

The Swiss federal circular on trusts treats the beneficiary of an irrevocable fixed interest trust much like a usufructuary. Assets and income are attributed to the beneficiary for tax purposes. Creating the trust counts as a gift from the settlor to the beneficiary. Distributions are in principle taxable income under Article 16, paragraph 1 of the federal direct tax law, and the beneficiary is subject to wealth tax on their share.

A revocable trust is different: it is treated transparently, and assets and income stay taxable with the settlor at their place of residence. A distribution to a beneficiary is then a gift, taxed at a cantonal rate. Whether a trust is revocable or irrevocable therefore changes the result, as explained in revocable and irrevocable trusts by legal system. Your own outcome depends on residence, canton and the beneficiaries' countries.

Seats compared for fixed entitlements

A worked example: a two-branch family

Example: a widowed entrepreneur in Lausanne has a son in Switzerland and a daughter who has settled abroad. They want each branch to receive an equal share of a family holding, with no room for argument about who gets what.

A fixed trust fits, because the deed can state two equal entitlements, the timing of payments and each branch's right to information. The questions then come in order. Which law governs the deed, so that both entitlements are enforceable against the trustee? Where will the trust be administered, and what will the trustee report? How will each branch be taxed, given they live in different countries? Is a family constitution useful alongside the deed?

The answers differ from case to case. For a family with children in different countries, see also a blended family with children in different countries.

What the confidential assessment establishes

The assessment sets out which law and seat best protect the fixed shares, how the trust would be reported, which tax questions need local advisers, and what could be done later if circumstances change, for instance by relocating an existing trust. It also flags the documents you should gather.
