Cook Islands Trust Succession After the Settlor’s Death

A Cook Islands trust does not end when the settlor dies. The trust continues under the same trust deed, administered by the same trustee company, with the same asset protection provisions intact.

Cook Islands law abolished the rule against perpetuities for international trusts, so a properly drafted Cook Islands trust can continue indefinitely across generations. That permanence only works if the trust deed anticipates what happens after the settlor dies: who takes over oversight, how the tax treatment changes, and how distributions shift from the settlor to the next generation.

What Happens Immediately After the Settlor Dies

The settlor’s death is a reportable event under both the trust deed and U.S. tax law. Several things happen simultaneously, and each requires a different response from a different party.

Notification to the trustee. The U.S. attorney or successor protector notifies the Cook Islands trustee of the settlor’s death. The trustee updates its records and begins operating under the succession provisions of the trust deed. If the settlor served as LLC manager (the standard structure for most asset protection trusts), the trustee or successor designated in the trust deed assumes management authority. The trustee does not act on instructions from family members or the settlor’s estate until the proper successor is identified and verified under the trust deed’s terms.

Protector succession. If the trust has a protector and the settlor served in that role, the successor named in the trust deed assumes it. The protector’s powers include the ability to remove and replace the trustee.

Form 3520 reporting. The settlor’s death is a reportable event on Form 3520, Part I. The deceased settlor’s final tax return and the Form 3520 reporting the death must be filed by the applicable deadline. The estate’s executor or personal representative is responsible for this filing.

Tax Reclassification After the Settlor’s Death

During the settlor’s lifetime, a Cook Islands asset protection trust is taxed as a foreign grantor trust under IRC sections 671 through 679. The IRS treats the settlor as the owner of trust assets for income tax purposes. All trust income flows through to the settlor’s personal return. The trust itself pays no U.S. income tax.

When the settlor dies, grantor trust status terminates. The trust becomes either a foreign nongrantor trust or a domestic trust, depending on the trust deed’s terms and the identities of the successor trustees and beneficiaries.

Foreign Nongrantor Trust Classification

If the trust continues with a Cook Islands trustee and U.S. persons do not have authority to control all substantial decisions, the trust is classified as a foreign nongrantor trust.

The trust itself becomes a separate taxpayer. Distributions to U.S. beneficiaries carry the distributable net income of the trust and are taxed to the beneficiary. Accumulation distributions (income earned but not distributed in prior years) are taxed under the throwback rules. The computation uses the average increase in the beneficiary’s tax across three of the five preceding years. IRC section 668 adds a non-deductible interest charge for the years the income accumulated.

The compliance burden changes. Form 3520-A is the annual return of a foreign trust with a U.S. owner. Once no U.S. person is treated as the trust’s owner, that return is no longer due. Each U.S. beneficiary who receives a distribution must report it on Form 3520.

A U.S. beneficiary reports the trust’s accounts on an FBAR if the beneficiary holds a present beneficial interest exceeding half the trust’s assets or receives more than half the year’s income. Form 8938 has its own asset thresholds.

Managing the Grantor-to-Nongrantor Transition

The shift from grantor to nongrantor trust status can be anticipated during the settlor’s lifetime. Trust deeds should include provisions that address how distributions will be handled after the settlor’s death. Accumulated income that was previously taxed to the settlor under the grantor trust regime is not subject to the throwback tax. Income earned after the settlor’s death and accumulated before distribution is subject to throwback.

Distributions made promptly after the settlor’s death carry income already taxed under the grantor trust rules. Distributions delayed by years may carry accumulated income taxed under the less favorable nongrantor rules. Many trust deeds address this by authorizing the trustee to distribute accumulated income promptly after death, minimizing throwback exposure.

Governance Transitions

Cook Islands trust deeds should specify every governance transition triggered by the settlor’s death. Three transitions require attention.

Protector Succession

A protector is optional. Cook Islands law does not require the office, and most trusts have no need of one. Where the deed creates it, the protector’s role grows more important after the settlor dies, because a protector who can remove and replace the trustee is able to act without a court application. If the position is vacant, the trustee operates without that check until a successor is appointed.

Well-drafted trust deeds name a chain of successor protectors. The chain should account for the possibility that the first successor may also be deceased, incapacitated, or unwilling to serve at the time the role passes.

LLC Management

If the trust holds assets through an offshore LLC (as most do), the settlor’s death typically terminates the settlor’s role as LLC manager. The trust deed or LLC operating agreement should specify the successor manager. In many structures, the trustee assumes management authority automatically upon the settlor’s death or incapacity.

Beneficiary Hierarchy

The trust deed’s distribution provisions typically shift after the settlor’s death. During the settlor’s lifetime, the settlor is usually the primary beneficiary. After death, the trust deed specifies who receives distributions, in what proportions, and under what conditions. Common structures include outright distribution to surviving children, continued trust administration for minor beneficiaries, and staggered distributions tied to age milestones.

If all named beneficiaries predecease the settlor and the trust deed contains no contingency provision, the trust may hold assets with no designated recipient. Well-drafted trust deeds address this by naming contingent beneficiary classes (such as the settlor’s descendants per stirpes) or granting the protector authority to add beneficiaries.

Asset Protection After the Settlor’s Death

Cook Islands trust protections do not expire when the settlor dies. The trust continues under Cook Islands law. The Cook Islands trustee still holds legal title. Cook Islands courts are closed to a foreign judgment against the trustee, a beneficiary, or the settlor, so far as that judgment rests on law the trust statute contradicts or relates to a matter Cook Islands law governs.

During the settlor’s lifetime, the primary threat is creditors of the settlor; after death, it is creditors of the beneficiaries. Section 13F of the International Trusts Act provides that a beneficiary’s interest in trust assets cannot be alienated or seized by creditors during the beneficiary’s lifetime if the trust includes spendthrift provisions. A properly drafted Cook Islands trust protects the beneficiaries’ interests from their own creditors the same way it protected the settlor’s assets from the settlor’s creditors.

The trust also bypasses U.S. probate entirely. Trust assets are not part of the settlor’s probate estate. They pass according to the trust deed, not the settlor’s will or state intestacy law. Cook Islands law reinforces this under Section 13E, which provides that a trust is not void or defective because it defeats heirship rights under foreign law. Forced heirship claims from jurisdictions that require mandatory inheritance shares are not recognized against Cook Islands trust assets.

Estate Tax Considerations

Cook Islands trust assets are usually included in the settlor’s gross estate under IRC §§ 2036 and 2038, because of the powers the settlor keeps over who eventually receives the trust property. The settlor’s eligibility for distributions during life is a weaker ground, because a discretionary beneficiary holds no enforceable right to them. The estate must report the trust assets and pay estate tax if the estate exceeds the federal exemption ($15 million per individual in 2026).

A Cook Islands trust provides asset protection during the settlor’s lifetime and after death, but it does not reduce federal estate tax. Trust assets included in the gross estate take their date-of-death value as a new basis, which can substantially reduce capital gains tax when beneficiaries eventually sell them.

Common Succession Planning Failures

Cook Islands trust succession failures are avoidable with proper documentation and periodic review. Three mistakes appear repeatedly.

No successor protector. The trust deed names one person as successor protector, that person predeceases the settlor, and no one updates the deed. The protector role sits vacant after the settlor’s death, leaving the trustee without oversight.

Stale beneficiary designations. The trust deed names beneficiaries based on the settlor’s family at formation. Twenty years later, the settlor has remarried, additional children have been born, and former beneficiaries are no longer appropriate. If the trust deed was never amended, the distributions after death may not reflect the settlor’s intentions.

No communication with the trustee. The settlor’s family has no relationship with the Cook Islands trustee and no understanding of how the trust works. After the settlor’s death, family members do not know who to contact, what documentation the trustee requires, or what the distribution timeline looks like.

Ongoing administration during the settlor’s lifetime should include periodic succession reviews, typically every three to five years, to verify that protector chains, beneficiary designations, and family circumstances remain current.
