How a Cook Islands trust works

The four roles

A Cook Islands trust is a relationship rather than a legal entity. Nothing is incorporated. What exists is a set of obligations recorded in a deed, owed by one party to others, and governed by the International Trusts Act 1984 and its amendments. Four roles carry the whole structure, and most misunderstandings about how these trusts work come from conflating them.

The settlor creates the trust and transfers assets to it. Once that transfer completes, the settlor owns nothing in those assets. That is not a technicality dressed up as a benefit. It is the mechanism, and everything protective about the arrangement follows directly from it. A creditor pursuing the settlor is pursuing someone who no longer holds the asset the creditor wants.

What the settlor gives up

The hardest part of a Cook Islands trust is not the paperwork. It is accepting that the assets are no longer yours in the way you are used to. Settlors who cannot accept this tend to build structures that fail, because they retain so much practical control that a court treats the trust as a sham and looks straight through it. Every reported failure involving a Cook Islands trust has turned on some version of this problem.

What you give up is ownership, and with it the ability to demand anything as of right. You cannot require the trustee to make a distribution. You cannot instruct the trustee how to vote shares. You cannot compel the trustee to sell an asset. If the deed gives you those powers directly, the structure is compromised before it is tested.

What the settlor keeps

The letter of wishes. A confidential, non-binding document to the trustee explaining how you would like the trust administered, who should benefit, and any guidance on specific assets. Trustees follow it closely in the ordinary course. A deed that made it binding would remove the trustee independence that makes the arrangement work. See letter of wishes.

Reserved powers. The deed can reserve specific authorities to the settlor, most commonly the power to direct investments through an underlying company where you act as manager. The more you reserve, the more exposed the structure becomes. See reserved powers.

The choice of protector. You choose who holds the protector role. You should not typically hold it yourself, for reasons central to how the structure performs under pressure. See settlor as protector.

What the trustee actually does

The trustee holds legal title to everything in the trust. They open accounts in the trust name, hold shares in any underlying company, sign contracts on behalf of the trust, and appear as the owner on every register. They owe fiduciary duties to the beneficiaries: to act in their interests, to act impartially between them, to keep proper accounts, and to exercise discretion honestly rather than mechanically.

What they do not do is take instructions from the settlor. They receive requests, weigh them against the letter of wishes and their duties to all beneficiaries, and decide. In the ordinary course they agree with a sensible request almost every time. The point is that they are not required to, and that gap between request and obligation is what a creditor cannot close.

Day-to-day administration

The trustee maintains the trust accounts and records, files the annual registration, monitors whether the qualifying conditions still hold, reviews and approves distributions, responds to correspondence from advisers and beneficiaries, and refreshes due diligence periodically as required by AML obligations. Expect an annual review and updated identity documents every few years as a matter of course.

The protector role

A protector is a check on the trustee. The role is not required by the Act but is present in almost every well-drafted Cook Islands trust. The power to remove and replace the trustee without going to court is the one that matters most: it means a trustee who underperforms, raises fees unreasonably, or changes ownership can be replaced. Without it the settlor is dependent on the outgoing trustee's cooperation to leave.

The protector must be genuinely independent of the settlor. A protector who will always do what the settlor wants is a conduit for the settlor's control. The Andersons in FTC v Affordable Media retained protector powers after being removed as co-trustees, and those retained powers produced the contempt finding. See settlor as protector.

Beneficiaries and distributions

Beneficiaries hold a discretionary expectancy. They may receive something. They cannot demand it. That distinction between an expectancy and a right is the mechanism: there is nothing fixed for a creditor to attach because there is nothing fixed to attach. A creditor pursuing a beneficiary's interest in a discretionary trust finds themselves pursuing a possibility rather than an asset.

How a distribution happens

A beneficiary, or the settlor on their behalf, writes to the trustee explaining what is needed and why. The trustee checks the request against the letter of wishes, considers the interests of all beneficiaries, obtains protector consent where the deed requires it, and pays. On a routine request with a funded account this takes days. On a first request or an unusually large one, expect questions and some delay.

The underlying company

Most Cook Islands trusts do not hold assets directly. The trust owns a limited liability company, and the company holds the assets. The settlor is often appointed manager of that company, making day-to-day investment decisions within limits the trustee sets. The trustee retains the ability to remove the settlor as manager. This solves the practical problem of day-to-day asset management while maintaining fiduciary oversight at the trust level.

The documents

Four documents do the substantive work. The trust deed is the constitution: names the parties, defines the beneficiary class, sets out trustee and protector powers, states the governing law, and contains the anti-duress provisions. The letter of wishes is confidential, non-binding guidance to the trustee, revised whenever circumstances change. The deed of settlement or transfer moves each asset into the trust. The solvency affidavit is a sworn statement of your financial position at the time of transfer, which goes directly to a statutory element under section 13B.

When a creditor arrives

A creditor with a foreign judgment cannot enforce it against the trust. The Act does not recognise foreign judgments in matters it governs, and the Cook Islands is not a party to the Hague Trust Convention. The creditor must commence entirely fresh proceedings in Rarotonga, within the statutory limitation period, and prove both limbs of section 13B beyond reasonable doubt.

What the Act does not restrain is a foreign court exercising jurisdiction over you personally. A judge who concludes you retain practical control can order repatriation and impose contempt sanctions. This is why trustee independence, protector independence, and minimised reserved powers all matter: they determine whether your inability to comply is genuine.

What the Anderson case actually shows

The Andersons established their Cook Islands trust in 1995, well before any FTC involvement. The FTC obtained a repatriation order. The Cook Islands trustee declared duress and refused. The anti-duress clause operated exactly as drafted. The assets stayed in the Cook Islands. The Cook Islands High Court upheld the trust and awarded costs against the FTC. The FTC settled with the trustee on confidential terms. The money never came back.

The Andersons were held in contempt because they had retained protector powers after being removed as co-trustees, giving the court a retained-control finding. The structure protected the assets. The structural error undermined the settlors' personal position. Those are different outcomes from different causes, and the case is evidence that the structure works, not that it fails. See the full case analysis.

Tax treatment for US settlors and beneficiaries

A Cook Islands trust settled by a US person is a foreign grantor trust for US tax purposes. The settlor reports the trust's income on their own return as if the trust did not exist for income tax purposes. This is not a tax shelter. The income is taxed exactly as if the settlor held the assets directly. The structure protects against civil creditors. It does not affect how the IRS treats the income.

Forms 3520 and 3520-A are filed annually. Form 3520 reports transactions with the foreign trust, including contributions and distributions. Form 3520-A is the annual information return for the trust itself. Both must be filed by a US settlor regardless of whether any transactions occurred in the year. The penalty for failure to file is the greater of $10,000 or specified percentages of the reportable amounts, and those penalties have been applied consistently. A CPA who prepares these forms regularly for foreign trust clients should handle both.

A US beneficiary who receives a distribution from the trust reports it on their own return under the foreign trust distribution rules. The distribution may have embedded foreign taxes or other attributes that affect how it is characterised. The mechanics are specific to the facts of each distribution and require advice from the same qualified CPA. Nothing about the Cook Islands location of the trustee changes the US tax obligations. The assets are fully in the US tax system for income purposes.
