Guernsey Foundation: A Guide to the Structure

How a Guernsey foundation works, covering councillors, guardians, beneficiaries, the disenfranchised, tax treatment, substance and common pitfalls.

For most of its history as a finance centre, Guernsey was a trust jurisdiction. Then, in 2013, it introduced a statutory foundation regime, and in doing so gave international families a second, distinct tool to sit alongside the trust. The Guernsey foundation has since become a favoured structure, particularly for families who want the substance of a trust in a form that civil-law systems readily recognise.

A foundation is neither a company nor a trust, but borrows from both. Like a company, it is an incorporated legal person that owns assets in its own name. Like a trust, it exists to benefit people or to pursue purposes rather than to make a profit for owners. There are no shareholders. This combination is what makes it so useful for succession and asset holding.

In this guide we explain how a Guernsey foundation is constructed, the roles that make it work, including the unusual and important concept of the "disenfranchised" beneficiary, and the tax and practical realities to weigh before establishing one.

What a Guernsey foundation is

A Guernsey foundation is created under the Foundations (Guernsey) Law and comes into existence on registration. Once registered, it is a body corporate with its own legal personality, capable of owning property, entering contracts and suing or being sued in its own name.

The foundation is governed by two documents: the constitution, comprising a charter and rules. The charter sets out the foundation's name, its purposes, its initial capital and the broad framework; certain details of the charter are registered. The rules govern the internal workings, the functioning of the council, the appointment of officials and the treatment of beneficiaries, and are generally kept private.

Because the foundation owns its assets outright, those assets are separated from the personal estate of the founder. This is the engine of its succession and protection value: there is no owner whose death triggers probate, and no shareholding to pass under a will.

The key roles

The founder. The founder endows the foundation with its initial assets and sets its purposes through the charter. As with other foundation regimes, the founder is frequently a professional acting for the real principal, and the founder's active role ends once the foundation is established.

The council. The council administers the foundation and carries out its purposes, broadly as a board would run a company. Councillors owe duties to act in good faith and in accordance with the constitution. The council is the operational heart of the structure.

The guardian. This is a distinctive feature. Where a foundation has purposes, or where its beneficiaries are disenfranchised (explained below), the law generally requires a guardian, a person who owes a duty to enforce the foundation's purposes and to act on behalf of those who cannot act for themselves. The guardian is the check on the council, comparable in spirit to the enforcer of a purpose trust or the protector of a foundation elsewhere. The guardian must, in general, be someone other than the sole councillor.

Enfranchised and disenfranchised beneficiaries

One of the most thoughtful features of Guernsey's regime is the distinction between enfranchised and disenfranchised beneficiaries.

An enfranchised beneficiary has information rights: broadly, the right to be told they are a beneficiary and to receive information about the foundation and its assets. A disenfranchised beneficiary has no such rights while disenfranchised; they cannot demand information or accounts during that period.

This allows a founder to provide for, say, young or vulnerable family members without giving them visibility of, or a sense of entitlement to, the foundation's wealth until an appropriate time. A beneficiary can move from disenfranchised to enfranchised under the rules, for example on reaching a certain age. Where beneficiaries are disenfranchised, the guardian's role becomes essential, since someone must be able to hold the council to account on their behalf.

Used well, this mechanism gives families a level of control over information flow that is difficult to achieve as cleanly in other structures.

Where the structure adds value

Succession planning. Because the foundation owns its assets, succession passes according to the rules rather than through a will or probate, privately and without the delays of administering an estate across jurisdictions.

Recognition by civil-law systems. Families from civil-law countries, where the trust is an unfamiliar concept, often find a foundation easier for their home courts, banks and advisers to understand and respect.

Holding and consolidation. Foundations are commonly used to hold company shares, investment portfolios and real estate under a single, durable framework.

Controlled information. The enfranchised and disenfranchised distinction allows careful management of what beneficiaries know and when, useful for younger generations or sensitive family situations.

Tax position and substance

Guernsey does not impose tax on a foundation's foreign income or gains in the ordinary case, and there is no Guernsey inheritance or capital gains tax. For a foundation holding non-Guernsey assets for non-resident beneficiaries, the Guernsey tax position is typically neutral.

As with every offshore structure, the decisive question lies elsewhere: how the founder's and beneficiaries' countries of residence treat the foundation. Many jurisdictions apply attribution, anti-avoidance and reporting rules that tax residents regardless of Guernsey's neutrality, and Guernsey participates in the Common Reporting Standard and maintains beneficial ownership records.

The honest assessment in 2026 is that a Guernsey foundation is a high-quality succession and holding vehicle, backed by a regulated and well-regarded finance centre, but it is not a means of avoiding tax due where you live. Its treatment must be confirmed with advisers in each relevant country before it is funded. Where the foundation holds active businesses, those underlying entities may face substance requirements of their own.

Common pitfalls

The first is excessive founder control. If the founder in reality continues to treat the foundation's assets as personal property, the separation that gives the structure its value can be challenged.

The second is a weak or conflicted guardian, particularly where beneficiaries are disenfranchised and have no other voice. The guardian must be genuinely able and willing to act.

The third is neglecting home-country reporting, which is where most serious problems originate. A foundation sound in Guernsey can cause real difficulty abroad if disclosure is overlooked.

The fourth is poorly drafted rules, since the rules carry the real substance of the arrangement and must reflect the founder's true intentions and adapt to changing circumstances.

How HPT helps

We advise families and founders on whether a Guernsey foundation fits their objectives, especially those seeking a civil-law-friendly succession vehicle from a regulated jurisdiction. Where it suits, we structure the council and guardian roles, calibrate the enfranchised and disenfranchised arrangements, draft rules that reflect your intentions, and coordinate with tax and legal advisers in each relevant country so the foundation is robust at home as well as in Guernsey.

If you are planning how to hold and pass on wealth across generations and borders, we would welcome the conversation.
