Foundation vs Trust: How They Differ for Family Asset Protection

By Hansruedi Mueller, Swiss foundation lawyer · Published 4 June 2026 · Last updated 4 June 2026

A foundation is an autonomous legal entity in which assets are irrevocably dedicated to a defined purpose; under the Swiss Civil Code, Article 80, it acquires its own legal personality. A trust is something different in kind: a fiduciary relationship, originating in the common law, in which a trustee holds and manages assets for the benefit of others. The trust is not a legal person and owns nothing in its own name.

That single distinction, an entity versus a relationship, drives almost every practical difference that follows: who owns the assets, who controls them, how they are recognised across borders, how private they stay, and how they are taxed.

Both structures are used by families, entrepreneurs and family offices for the same broad goals: protecting assets, planning succession across generations, and keeping arrangements confidential. Neither is universally “better”. The right choice depends on your family’s residence, your appetite for control versus durability, and the jurisdictions involved. This guide compares the two honestly, with a particular focus on how each works in and around Switzerland.

Key takeaways

• A foundation is a legal entity with its own legal personality (ZGB Art. 80); a trust is a fiduciary relationship with no separate legal personality.
• A foundation owns its assets; in a trust the trustee holds legal title for the beneficiaries.
• Switzerland has no domestic trust law but recognises foreign trusts under the Hague Convention, in force here since 1 July 2007.
• A foundation tends to suit durable, purpose-bound governance; a trust tends to suit flexible, settlor-influenced, private arrangements.
• A Swiss family foundation is generally not tax-exempt; a charitable foundation can be, if it genuinely serves a public utility.

Foundation vs trust at a glance

The table below summarises the principal differences. Swiss-law points are noted where they apply; the trust column describes a typical common-law trust as recognised in Switzerland.

Read the table as a starting point, not a verdict. The right structure depends on the people and jurisdictions involved, as the sections below explain.

Legal nature, entity versus relationship

A Swiss foundation is a thing the law recognises in its own right. You endow assets, define a purpose, and, on registration in the commercial register, where required, a new legal person comes into existence.

Swiss Civil Code, Article 80: “A foundation is established by the endowment of assets for a particular purpose.”

Swiss foundations are governed by the Swiss Civil Code, Articles 80–89c. Because the foundation is a person in law, it can hold property, contract, sue and be sued. It has no owners and no shareholders, only beneficiaries and a purpose.

A trust is not a person at all. It is a relationship created when a settlor transfers assets to a trustee, who is bound by fiduciary duty to manage them for beneficiaries under the terms of a trust deed. Legal title sits with the trustee; the benefit sits with the beneficiaries, a division that common-law jurisdictions call the split between legal and beneficial ownership. There is no separate entity in between. This is why a civil-law country such as Switzerland, which had no native concept of split ownership, needed an international treaty to accommodate trusts at all, a point we return to below.

Control and governance

Once a Swiss foundation is established, the founder steps back. Day-to-day direction passes to the foundation council (Stiftungsrat), which must act within the purpose fixed in the foundation deed. The founder cannot simply reverse course later; the dedication of assets is irrevocable, and the purpose is hard to change. For charitable foundations, a supervisory authority oversees the board and can intervene if it strays.

That permanence is a feature, not a flaw, it is what lets a foundation carry a family’s intentions forward for generations without being unwound on a whim. But it does mean less flexibility.

A trust is usually more flexible. The settlor can shape it precisely in the deed, appoint a protector to supervise the trustee, and leave a non-binding letter of wishes to guide discretionary decisions. The trust deed also defines beneficiary rights, whether beneficiaries hold fixed entitlements or are merely objects of the trustee’s discretion. Trusts can be revocable or irrevocable. A settlor who wants to keep a guiding hand will often find a trust more accommodating than a foundation, though retaining too much control can undermine the asset protection and tax treatment the structure was meant to deliver.

Recognition and the Hague Convention

A Swiss foundation is recognised automatically in Switzerland, because it is a Swiss entity. A trust needs a bridge, and that bridge is an international treaty.

Switzerland has no domestic trust law. You cannot create a “Swiss trust” governed by Swiss substantive law. What Switzerland does instead is recognise trusts validly created under a foreign law, such as English or Jersey law, through the Hague Convention on the Law Applicable to Trusts and on their Recognition.

Hague Convention: The Convention entered into force in Switzerland on 1 July 2007. On the same date, Switzerland amended its Federal Act on Private International Law (PILA) and its Debt Enforcement and Bankruptcy Act so that trust assets are treated as a segregated fund, separate from the trustee’s personal estate.

The Convention does not create trust law; it provides rules for determining which law governs a trust and requires the recognising state to treat the trust property as a distinct fund. We cover the practical mechanics in our guide to recognition of foreign trusts in Switzerland under the Hague Convention.

Recognition also has a regulatory dimension. A professional trustee operating in Switzerland is a supervised financial institution: under the Financial Institutions Act (FinIA), Article 17(2), regulated trustee services are defined as “the management or holding of segregated funds on a fiduciary basis on behalf of the beneficiaries of a trust, pursuant to the Hague Convention”. In practice this means a Swiss-based trustee requires a FINMA licence and is overseen by a supervisory organisation, a point in the trust’s favour, because the assets sit with a regulated fiduciary rather than an unsupervised individual.

It is worth being precise about a frequently misreported point. Switzerland did explore introducing its own domestic trust: a preliminary draft went to public consultation in January 2022. After significant criticism, chiefly of the proposed tax treatment, the project was not adopted, and the relevant parliamentary committee endorsed writing it off in late 2023. Attention shifted instead to liberalising the family foundation, with Parliament adopting a motion to that effect on 27 February 2024. As of mid-2026, there is still no Swiss trust law, and the family-foundation reform is in drafting. Treat any claim that “Switzerland now has its own trust” with caution.

Privacy and disclosure

Privacy is one of the more nuanced comparisons, and it cuts differently for different foundation types.

A Swiss family foundation is not entered in the commercial register, which makes it comparatively confidential. A charitable or corporate foundation, by contrast, is registered and supervised, so more information is on the public record.

A trust is generally not subject to public registration, which has traditionally made it the more private of the two structures. That said, privacy is narrowing everywhere: beneficial-ownership transparency rules, automatic exchange of financial information and anti-money-laundering reporting now reach into both trusts and foundations. Privacy should be understood as confidentiality from the public, not opacity towards tax authorities.

Asset protection

Both structures can protect family wealth from future, unforeseen claims, but only if they are set up properly and in good time.

A Swiss foundation protects assets once they have been irrevocably endowed: they belong to the foundation, not the founder, so a founder’s later personal creditors generally cannot reach them. The protection is not absolute. Transfers made to defeat existing creditors can be clawed back under Swiss insolvency rules, and forced-heirship entitlements may still bite. We explain how this works for families in our guide to Swiss family foundation asset protection.

A trust protects assets as a segregated fund held by the trustee: the settlor’s personal creditors cannot ordinarily claim them. Its classic weaknesses are the sham trust (where the settlor never truly relinquished control), excessive settlor powers, and challenges under forced-heirship or fraudulent-transfer rules.

The honest conclusion is that neither structure is a shield against legitimate claims, fraud or tax obligations. Both work best when established well before any dispute, with genuine relinquishment of control. Jurisdiction also matters, see our comparison of the best jurisdictions for family-foundation asset protection.

Taxation

A foundation is a separate tax subject in Switzerland. This is where an important caveat applies: a Swiss family foundation is generally not tax-exempt. It is taxed as an entity, and distributions can carry their own consequences. A charitable foundation, by contrast, can obtain a tax exemption, but only if it genuinely serves a public utility, and the exemption is reviewed by both the supervisory authority and the tax office. It is never automatic.

A trust is treated differently. Switzerland has no special trust tax regime, so a trust is taxed by looking through to the residence of the settlor or beneficiaries and applying ordinary rules. For internationally mobile families this can become complex. US persons face additional reporting and anti-deferral rules, covered in our guide for US citizens and FATCA, and UK residents face settlor-interested and inheritance-tax considerations, addressed in our guide for UK residents. Tax outcomes turn on personal facts, so neither structure should be chosen on tax grounds alone.

Set-up and ongoing cost

A Swiss foundation is established by a notarised foundation deed and an endowment of assets. There is no statutory minimum capital, but cantonal supervisory authorities in practice expect a meaningful endowment, commonly around CHF 50,000 for a charitable foundation, and considerably more for one intended to operate independently. Supervised foundations carry ongoing audit and reporting duties, which add to the running cost.

A trust has no minimum capital requirement. Its costs are mainly the trustee’s fees and the drafting of the trust deed, plus ongoing administration. Over time, professional trustee fees can rival or exceed foundation running costs, so a like-for-like budget comparison matters more than the headline set-up figure.

Charitable trust vs foundation

The phrase “charitable trust vs foundation” comes up often, and the answer depends partly on where you are.

A charitable trust is a common-law arrangement: a trustee holds assets and applies them to charitable purposes, frequently as a grant-making vehicle. There is no separate entity, the trustee carries the obligations.

A charitable foundation is an entity with its own legal personality, run by a board. In Switzerland, a charitable foundation is registered, supervised by the Federal Supervisory Authority for Foundations (ESA), and can be tax-exempt where it serves a genuine public utility. Setting one up is a defined process, see our guide to creating a charitable foundation in Switzerland.

A few practical distinctions:

• Personality: the foundation is a legal person; the charitable trust is a relationship run by trustees.
• Oversight: a Swiss charitable foundation answers to the ESA; a charitable trust answers to its deed and the relevant charity regulator.
• Terminology: in the United States, “charitable trust” and “private foundation” are distinct tax categories under the Internal Revenue Code; in Switzerland the working comparison is charitable foundation versus a foreign charitable trust.

For most clients seeking a durable, supervised philanthropic vehicle on Swiss soil, the charitable foundation is the natural choice; the charitable trust suits those already operating in a common-law framework.

Which should you choose?

There is no universal winner. As a rule of thumb:

Choose a foundation if you want:

• a recognised legal entity on Swiss soil, with institutional governance that outlasts any individual;
• a fixed purpose that carries a family’s intentions across generations, often the stronger choice for long-term estate planning with defined objectives;
• a charitable or public-utility vehicle that can qualify for tax exemption; or
• to operate in a civil-law country where trusts are unfamiliar or distrusted.

Choose a trust if you want:

• maximum flexibility, with the ability to shape and adjust arrangements over time;
• continued settlor influence through a protector and letter of wishes;
• a higher degree of privacy, with no public register; or
• to plan within a common-law family already comfortable with trusts.

Cross-border facts often decide the question. Expatriate families, UK residents and US persons each face distinct tax and reporting rules, and the choice of jurisdiction, Switzerland, Liechtenstein, Panama or elsewhere, can matter as much as the choice between the two structures themselves.

Frequently asked questions

What is the main difference between a foundation and a trust? A foundation is an autonomous legal entity with its own legal personality (Swiss Civil Code, Article 80), so it owns its assets directly. A trust is a fiduciary relationship with no separate legal personality, in which a trustee holds legal title to the assets for the beneficiaries.

Does Switzerland recognise foreign trusts? Yes. Switzerland has no domestic trust law, but it recognises trusts validly created under a foreign law through the Hague Convention on the Law Applicable to Trusts and on their Recognition, which has been in force in Switzerland since 1 July 2007. Trust assets are treated as a segregated fund.

Is a trust or a foundation more private? Trusts are generally not entered in a public register, so they have traditionally offered more privacy. Among foundations, a Swiss family foundation is not registered in the commercial register and is comparatively confidential, whereas charitable foundations are registered and supervised. In all cases, tax-transparency and anti-money-laundering rules now apply.

Which offers better asset protection, a foundation or a trust? Both can strongly protect assets once they are irrevocably transferred and genuinely out of the founder’s or settlor’s control. A foundation protects endowed assets as its own property; a trust protects them as a segregated fund. Neither defeats legitimate creditors, fraudulent-transfer rules or forced-heirship claims, and the outcome depends on the jurisdiction and the design.

What is the difference between a charitable trust and a foundation? A charitable trust is a common-law arrangement run by trustees, with no separate legal entity. A charitable foundation is an entity with its own legal personality and a board; in Switzerland it is supervised by the Federal Supervisory Authority for Foundations and can be tax-exempt if it serves a genuine public utility.

Can I set up a trust under Swiss law? No. There is no Swiss substantive trust law, so a trust cannot be governed by Swiss law. You can, however, create a trust under a foreign law and have it recognised in Switzerland under the Hague Convention. If you want a Swiss-law structure, a foundation is the entity to consider.

Who owns the assets in a trust versus a foundation? In a trust, legal title to the assets is held by the trustee in that capacity, while the beneficial interest belongs to the beneficiaries, a split that civil-law systems call the separation of legal and beneficial ownership. In a Swiss foundation, the foundation itself owns the assets outright as an autonomous legal entity; there is no trustee and no split title.

Is a Swiss family foundation tax-exempt? Generally, no. A Swiss family foundation is a separate tax subject and is taxed as an entity; income and capital are subject to Swiss income and wealth tax at cantonal and federal level. Only a foundation that genuinely serves a public utility may apply for a tax exemption, and that exemption is reviewed, it is never automatic and does not apply to private family foundations.

What minimum capital is required to set up a Swiss foundation versus a trust? Swiss law prescribes no statutory minimum endowment for a foundation, but cantonal supervisory authorities in practice expect a meaningful sum, commonly around CHF 50,000 for a charitable foundation seeking supervision and tax exemption, and often considerably more for an operationally independent entity. A trust has no minimum capital requirement; costs are principally trustee fees and deed drafting, though ongoing professional trustee fees can rival foundation running costs over time.

Can a foundation or trust be used to avoid forced-heirship rules in Switzerland? Neither structure reliably overrides Swiss forced-heirship rules. Protected heirs retain their reserved portion (Pflichtteil) under Swiss succession law, and assets transferred to a foundation or a trust can be drawn back into the reckoning and reduced (Herabsetzung) to restore those reserved shares. The same limits are confirmed by Swiss Federal Supreme Court case law for trusts and by the supervisory framework for foundations.

What is a protector in a trust, and is there an equivalent in a foundation? A protector is an optional role in a trust deed, typically held by an individual or a committee, with powers to supervise the trustee, veto certain decisions, or even replace the trustee. Swiss foundations have no direct equivalent, though a founder may include supervisory rights in the statutes or reserve amendment powers for a particular body. In practice, the foundation council’s oversight duties and the supervisory authority’s role together serve a broadly comparable function.

How does registration and public disclosure differ between a foundation and a trust? A Swiss charitable or corporate foundation must be entered in the commercial register and is supervised by a cantonal or federal authority, so basic information is publicly accessible. A Swiss family foundation is not entered in the commercial register, making it more confidential. A foreign trust operating in Switzerland is generally not subject to public registration, which has traditionally made it the more private arrangement, though beneficial-ownership transparency and automatic exchange of information now reduce privacy for both structures relative to tax authorities.

Is it possible to convert a foundation into a trust, or vice versa? No direct conversion mechanism exists under Swiss law. A foundation, once registered, is a separate legal entity with a fixed purpose that can only be modified in exceptional circumstances under ZGB Article 86. A trust is a relationship governed by its chosen foreign law. Families wishing to move from one structure to the other typically wind down the existing arrangement and establish a new one, which has tax, legal and timing implications that require specialist advice.
