Concept
Trusts are a family of structures with a common arrangement: the settlor transfers the assets, the trustee manages them, the beneficiary receives the benefit. The trust's basic operation is covered separately. The type of trust determines who really controls the assets, how well they are shielded from creditors and heirs, and how they are taxed. An unsuitable choice results in weak protection and unexpected tax liabilities.
The classification of trusts is rooted in common-law trust concepts; civil-law systems may use different forms. The history of the split between legal ownership and benefit is explained in How a trust works.
Discretionary and Fixed
In a discretionary trust the trustee itself decides which members of the beneficiary class receive a distribution, and how much; no one holds a guaranteed share. The settlor leaves a non-binding letter of wishes, but the discretion formally belongs to the trustee — this provides maximum flexibility and protection: assets to which a beneficiary has no entitlement are difficult to reach through a claim by their creditor or former spouse. In a fixed trust the shares are set in advance and predictable; that rigidity is more transparent to the tax authority but provides less protection and does not adapt to changes in family circumstances. Estate planning is therefore dominated by the discretionary form.
Revocable and Irrevocable
A revocable trust can be amended or wound up by the settlor at any time. That is convenient for managing property during life, but it usually gives no protection from creditors and no tax advantage: for both a court and the tax authority the assets are still treated as the settlor's. An irrevocable trust is a genuine transfer without a right of revocation; it is the form that shields assets and is used in estate planning. Parting with control entirely is not required for this: reserved powers regimes let the settlor keep the right to approve investments and distributions while preserving irrevocability.
Special Types
Life Interest Trust
One beneficiary — most often the surviving spouse — receives for life the income or the right to use the property, and on their death the capital passes to the next in line, usually children from an earlier marriage. This is a traditional arrangement for a second marriage and phased transfers across generations. In England such structures are closely linked to inheritance tax, whose regime changed noticeably after the 2025 reform.
Purpose Trust
A purpose trust has no individual beneficiaries: it is held for a stated purpose, and an enforcer supervises its execution. Such trusts are convenient for holding the shares of a PTC or a family holding company, as well as for charity and the orphan structures used in transactions. Separate statutory regimes provide for them: the Cayman STAR (Special Trusts (Alternative Regime) Law 1997) allows a trust for persons, purposes, or both at once, while the British Virgin Islands VISTA (2003) is tailored to holding the shares of an operating company. Detailed analysis is provided in the article on the purpose trust.
Bare Trust
In a bare trust (also called a simple trust) the trustee remains solely a holder of title, and the beneficiary may demand transfer of the assets to themselves at any time. For tax purposes the structure is transparent: income and gains are treated as the beneficiary's income directly. It is used to hold assets in the name of minors, as a nominee holding, and as a technical link inside a more complex structure.
Spendthrift and Protective Trusts
When capital must be protected from the beneficiary or their creditors, protective forms are used. The American spendthrift trust bars the beneficiary from pledging or selling future distributions, and creditors from reaching them before distribution. The offshore asset protection trust (Cook Islands, Nevis) rests on short limitation periods and firewall provisions that cut off foreign judgments. The effectiveness of any of these forms depends on timing: the trust must be established long before a specific creditor or claim appears.
Reserved Powers, STAR and VISTA
The earlier doctrine required the settlor to relinquish control entirely. Offshore laws softened this: reserved powers regimes (the first was the Cayman Trusts (Immediate Effect and Reserved Powers) Law 1987) let the settlor keep investment decisions, the approval of distributions, and the appointment and removal of the trustee — and the trust nevertheless remains valid. Jersey and Guernsey add firewall protection to this. VISTA goes further still and lifts from the trustee the "anti-Bartlett" duty to intervene in the affairs of the company whose shares are held in the trust: the family business continues to be run as before. Excessive control creates a risk of a sham.
Foundation as a Related Form
In continental legal systems, which had no trust, the corresponding form was the foundation. A foundation (Stiftung) is a standalone legal entity without members, governed by a council under the founder's charter; in effect it is close to an irrevocable discretionary trust while being more comprehensible to civil law and to registers. The family foundation of Liechtenstein and the Panama private interest foundation are typical examples; paired with a PTC, the foundation often holds the trust company itself.
In a combined structure, a foundation or a purpose trust holds the shares of the trust company, and the PTC in turn acts as trustee of the family trust.
Recognition and Regulation
The main weakness of a trust outside the common law is that it may not be recognised. The Hague Convention on the Law Applicable to Trusts and on their Recognition (1985, in force since 1992) was conceived as the solution and has 14 contracting parties — mainly common law plus a few civil-law ones: Switzerland, Italy, the Netherlands, Luxembourg, Liechtenstein, Monaco. France, Germany and Russia have not become parties, so the effect of a trust in those countries is not guaranteed. A separate issue is forced heirship: the compulsory share of heirs in many jurisdictions collides with the firewall provisions of offshore centres, and the outcome of the dispute is decided by whose court hears it.
A court may declare a trust a sham if the settlor never actually relinquished control and the trustee merely carries out the settlor's instructions. The use of statutory reserved powers does not by itself create a sham — unlimited actual control does. That is why the line between retained influence and a sham transfer is recorded in documents; oral arrangements with the trustee only do harm here.
For tax transparency purposes, trusts have long ceased to conceal information. CRS first distinguishes a trust that is a Financial Institution from one that is an NFE. For a Passive NFE trust, the controlling-person definition covers the settlor, trustee, protector and beneficiaries without requiring each to exercise practical control. Reporting still depends on reportable-person status, the beneficiary rules under domestic implementation and the relevant exchange relationship. For settlors and beneficiaries who are Russian tax residents, the Russian CFC rules require a separate assessment of control over the foreign structure without legal personality, notification duties and the conditions for taxing its profit — the detail is in the analysis of trusts and CFC. (Sources: OECD: CRS handbook; OECD: CRS FAQ; FNS: CFC).
How to Choose
Selection by objective: for asset protection and transfer to heirs, an irrevocable discretionary trust fits; for a surviving spouse — a life interest; for holding the shares of a holding company or a PTC — a purpose trust or VISTA; for enhanced protection from creditors — an offshore asset protection trust. Every choice is then checked against the compulsory share of heirs, the CRS regime, and the tax residence of the beneficiaries. The jurisdiction of establishment is a separate question: how these forms are combined in practice — a licensed trustee, a PTC and a family office trust — is covered in the review of trust structures in Singapore.
Trust Types Side by Side
Trust types can be compared using the same criteria: who decides distributions, how much control the settlor retains, what a creditor can reach, how the income is usually taxed, and the form's uses. The tax column gives the typical pattern in the US and UK systems where these forms originated; how a given country treats a foreign trust is a separate question, answered country by country in relocating with a trust and trust taxation.
| Type | Who decides distributions | Settlor's control | Creditors of the settlor / of a beneficiary | Typical tax pattern | Typical task |
|---|---|---|---|---|---|
| Discretionary | The trustee, within a class of beneficiaries | Letter of wishes only, unless powers are reserved | Settlor's creditors cut off if settled in time / a beneficiary has no right to attach | The trust is a taxpayer; beneficiaries taxed on what they receive (UK trust rate 45%; US non-grantor trust) | Dynastic planning, protection, flexibility |
| Fixed / interest in possession | The deed: shares fixed in advance | None after settlement | Cut off / a fixed share can be reached by that beneficiary's creditor | Beneficiary taxed on the income to which they are entitled | Predictable shares, tax transparency |
| Revocable (living trust) | The settlor, while alive | Full: amend or revoke at will | Open to the settlor's creditors / — | Settlor taxed as owner (US grantor rules, IRC § 676); assets stay in the settlor's estate | Probate avoidance, incapacity planning |
| Life interest | The deed: income or use to the life tenant, capital to remaindermen | None after settlement | Cut off / the life tenant's income interest is exposed | Life tenant taxed on income; UK: an interest created by will (IPDI) sits in the life tenant's estate, a lifetime one falls into the relevant-property regime | Second marriage, phased transfer |
| Bare | The beneficiary: can call for the assets at any time | None | — / fully exposed | Transparent: the beneficiary is taxed as owner | Nominee holding, assets of minors |
| Purpose (STAR, VISTA, Jersey, Bermuda) | The trustee, policed by an enforcer; no beneficiaries needed | Through the enforcer and reserved powers | Cut off / no beneficiary to pursue | No beneficiary to tax; offshore usually no tax at trust level | Holding PTC or family-company shares, orphan vehicles |
| Spendthrift / asset protection | The trustee; beneficiary barred from assigning | Self-settled forms let the settlor stay a beneficiary | Short limitation, firewall, higher burden of proof / distributions shielded until paid | Self-settled forms usually taxed on the settlor (US DAPT is a grantor trust) | Protection against future creditors |
| Reserved powers | The trustee, subject to the settlor's reserved consents | Investment, distribution and appointment powers kept by statute | Protected if powers stay within the statute; excess control invites a sham finding | Often attributed to the settlor where the settlor retains benefit or control | Founder keeps the business decisions |
Control and taxation are the main considerations. Control runs from the revocable trust, where the settlor still owns everything for a court and a tax authority, to the discretionary and purpose trusts, where nobody holds a right that a creditor could seize; greater control means weaker protection. The tax column follows the same line: the more the settlor keeps, the more likely the income is taxed on the settlor, and the more the trustee decides, the more the trust itself becomes the taxpayer.
In practice, structures combine several trust types. A family business is typically held under a VISTA or purpose trust so the trustee does not interfere, the dividends flow into a discretionary trust for the family, and a life interest provides for a surviving spouse. The type answers what the trust does; the jurisdiction answers whether the chosen form, firewall and reserved powers are available at all, and that comparison is set out in the trust jurisdictions map. For civil-law families the parallel choice between a trust and a foundation is set out in private foundations.
Task → type
| Task | Type | What to check next |
|---|---|---|
| Pass wealth over generations with flexibility | Irrevocable discretionary | Perpetuity limit and firewall of the chosen jurisdiction |
| Provide for a second spouse, keep capital for children | Life interest | Forced heirship of the children; UK IPDI treatment |
| Hold the family company without trustee interference | VISTA or purpose trust with a PTC | Enforcer, directors, economic substance |
| Avoid probate, keep full control | Revocable | No protection and no estate-tax saving |
| Protect against future creditors | Self-settled asset protection trust | Timing, solvency at settlement, the home court's view of self-settled trusts |
Q/A
Which trust type gives the settlor the most control, and what are the consequences?
The revocable trust: the settlor can amend or revoke it at will. The consequence is that a court and a tax authority treat the assets as still the settlor's — no protection from the settlor's creditors, and in the US the assets stay in the settlor's taxable estate under the grantor rules. Reserved powers regimes are the middle ground: statutory powers over investment, distributions and appointment are kept while preserving irrevocability, provided actual control does not turn the trust into a sham.
Why do family structures often combine a purpose trust and a discretionary trust?
Because each covers a different task. A purpose trust or VISTA holds the shares of the PTC or the operating company, so no beneficiary has a right that could be attacked and the trustee does not interfere in management; a discretionary trust receives the economic value and distributes it to family members as needs change. The combination separates control of the business from benefit to the family.
Can the settlor keep control over the assets after settling a trust?
Partially — through statutory reserved powers regimes: the settlor may retain investment decisions, the approval of distributions, and the appointment and removal of the trustee, and the trust remains valid. The boundary is unlimited actual control: if the trustee merely carries out the settlor's instructions, a court may declare the trust a sham. The line between retained influence and a sham transfer is fixed in the trust documents; oral arrangements with the trustee only do harm.
Which type of trust protects assets from creditors?
An irrevocable discretionary trust: assets to which a beneficiary has no entitlement are difficult to reach through a claim by their creditor or former spouse. For enhanced protection, an offshore asset protection trust (Cook Islands, Nevis) adds short limitation periods and firewall provisions. Timing decides the outcome: the trust must be established long before a specific creditor or claim appears.
Does a revocable trust give protection or tax advantages?
Usually no. While the settlor can amend or wind up the trust at any time, both a court and the tax authority treat the assets as still the settlor's. A revocable trust serves to manage property during life; protection and the estate-planning effect come with the irrevocable form.
Can tax authorities receive information about a trust?
Potentially. CRS first distinguishes a trust that is a Financial Institution from one that is an NFE. For a Passive NFE trust, the controlling-person definition covers the settlor, trustee, protector and beneficiaries without requiring each to exercise practical control. Reporting still depends on reportable-person status, the beneficiary rules under domestic implementation and the relevant exchange relationship. For settlors and beneficiaries who are Russian tax residents, the CFC logic requires separate checks of control over the foreign structure, notification duties and any taxation of its profit.
What happens to a trust in a country that does not recognise it?
Its effect is not guaranteed. The Hague Convention of 1985 has 14 contracting parties; France, Germany and Russia have not become parties. The second risk is forced heirship: the compulsory share of heirs collides with the firewall provisions of offshore centres, and the outcome is decided by whose court hears the dispute.
