Choosing a Swiss Professional Trustee: What to Look For

By Hansruedi Mueller, Swiss foundation lawyer · Published 21 July 2026 · Last updated 21 July 2026

A professional trustee holds and administers trust assets for the benefit of others, and choosing the right one is one of the most consequential decisions a settlor makes. Since 1 January 2020, professional trustees operating in Switzerland need authorisation from the Swiss Financial Market Supervisory Authority (FINMA) under the Financial Institutions Act. That single change turned trusteeship from a largely unregulated activity into a supervised financial service, and it should be the first thing you check.

Switzerland has no trust law of its own, so a Swiss trustee administers a trust governed by a foreign law, English, Jersey, Guernsey and similar, while operating from a well-regulated financial centre. That combination, foreign-law flexibility with Swiss stability and supervision, is why many international families base their trustee here. This guide sets out what to look for, and the questions worth asking before you appoint anyone.

Choosing a trustee is not only a technical exercise. You are handing control of family assets to an institution that may hold them for decades, so competence and authorisation matter, but so do independence, continuity and the quality of the working relationship.

Key takeaways

• Professional trustees in Switzerland have needed FINMA authorisation since 1 January 2020, verify it first.
• A Swiss trustee administers a foreign-law trust, so expertise in the trust’s governing law is essential.
• Look for independence, continuity and clear fees, not just size or a familiar name.
• Trustees are subject to anti-money-laundering duties and ongoing supervision by a supervisory organisation.
• The trustee holds real power over your assets, so fit and governance matter as much as price.

Start with authorisation

Confirm the trustee is authorised by FINMA. Under the Financial Institutions Act, in force since 2020, a trustee acting professionally in or from Switzerland must hold a FINMA licence, affiliate with a supervisory organisation that monitors ongoing compliance, and meet requirements on fit-and-proper management, organisation, minimum capital and risk control. A firm that cannot show its authorisation, or that claims it does not need one, is a firm to walk away from.

Authorisation is a floor, not a guarantee of quality, but it tells you the trustee is supervised, has passed a competence and integrity check, and is accountable to a regulator. Ask for the authorisation details and the name of the supervisory organisation, and confirm them. This one step filters out much of the risk that existed before 2020.

Match expertise to the trust’s governing law

A Swiss trustee administers a trust under foreign law, so the right expertise is specific. If your trust is governed by Jersey or English law, your trustee needs genuine command of that law, not general fiduciary experience. Ask which governing laws the firm works with regularly, how it handles the interaction between the trust’s law and Swiss tax and reporting, and whether it has handled structures like yours, cross-border families, business assets, philanthropy, or whatever your case involves.

Depth in the relevant law shows up in the detail: how the trustee approaches distributions, how it documents decisions, how it manages a letter of wishes, and how it deals with beneficiaries in different countries. A trustee fluent in the trust’s law and in Swiss cross-border practice will keep you out of trouble that a generalist may not even see.

Weigh independence, continuity and fees

Independence protects beneficiaries. A trustee tied to a bank or a product may face pressure over where assets are held or invested. An independent trustee can choose custodians and managers on the merits, which matters over the long life of a trust. Ask how the trustee is remunerated, whether it takes commissions from banks or managers, and how conflicts are handled.

Continuity matters because a trust outlives people. Ask what happens if your lead contact leaves, how the firm ensures institutional memory, and whether it is stable enough to serve the trust for decades. On fees, insist on clarity: a transparent schedule, fixed or time-based, with a clear line on what is included and what is extra, beats a low headline rate with open-ended add-ons. The cheapest trustee is rarely the right one, and the most expensive is not automatically the best.

Do not overlook AML and reporting

A professional trustee carries real compliance duties, and that is a feature, not a nuisance. Swiss trustees are financial intermediaries under anti-money-laundering law: they must verify the settlor and beneficiaries, understand the source of funds, and monitor the trust. Expect thorough onboarding questions; a trustee that skips them is not protecting you, it is exposing you.

The trustee also sits at the centre of the trust’s tax and information reporting, including exchange-of-information obligations. Ask how it handles reporting for beneficiaries in different countries, and how it keeps trust accounts that separate income from capital, which, as our note on trust distribution tax explains, directly affects a Swiss-resident beneficiary’s tax. A trustee whose records are clean makes everyone’s compliance easier.

Foundation or trust?

For some families a Swiss foundation is a better fit than a trust with a Swiss trustee, because a foundation is a domestic legal entity rather than a foreign-law arrangement administered here. The two solve overlapping problems in different ways, and the right choice depends on your goals, your family’s location and how you want control to work.

Frequently asked questions

Do trustees in Switzerland need a licence? Yes. Since 1 January 2020, a professional trustee acting in or from Switzerland must be authorised by FINMA under the Financial Institutions Act, affiliate with a supervisory organisation, and meet requirements on management fitness, organisation, capital and risk control. Verifying authorisation should be your first step when choosing a trustee.

What law governs a trust administered by a Swiss trustee? A foreign law, because Switzerland has no trust law of its own. A Swiss trustee typically administers a trust governed by English, Jersey or Guernsey law, while operating from a regulated Swiss base. That is why expertise in the trust’s specific governing law is essential when choosing a trustee.

How do I check a Swiss trustee is properly authorised? Ask the firm for its FINMA authorisation details and the name of its supervisory organisation, and confirm them. A trustee that cannot evidence authorisation, or that argues it is not required, should be avoided, because professional trusteeship in Switzerland has been a supervised activity since 2020.

What should I ask about fees? Ask for a clear, written fee schedule, whether charging is fixed or time-based, what is included, and what triggers extra charges. Ask too whether the trustee receives commissions from banks or asset managers, since those affect both cost and independence. Transparency matters more than a low headline rate.

Why does trustee independence matter? An independent trustee can choose custodians and investment managers on the merits, rather than being steered by a parent bank or an in-house product. Over the decades a trust may last, that freedom protects beneficiaries and usually improves outcomes. Ask how the trustee is owned, how it is paid, and how it manages conflicts.

What happens if my main contact at the trustee leaves? A well-run trustee has institutional continuity: documented decisions, team coverage and a stable organisation, so the trust is not dependent on one person. Ask directly how the firm preserves knowledge and continuity, because a trust can outlast several generations of staff.

Are Swiss trustees subject to anti-money-laundering rules? Yes. Professional trustees are financial intermediaries under Swiss anti-money-laundering law, so they must identify the settlor and beneficiaries, establish the source of funds, and monitor the trust. Rigorous onboarding is a sign the trustee is doing its job, not an obstacle.

Is a foundation a better option than a trust for me? It can be, especially if you prefer a Swiss domestic legal entity to a foreign-law arrangement administered in Switzerland. A foundation and a trust address overlapping goals differently, and the better fit depends on your family, your assets and how you want control exercised. Compare the two before deciding.
