Why LLCs Are the Primary Funding Vehicle
Most Cook Islands Trust structures don’t hold assets directly in the trust’s name. They hold them through an underlying LLC — the trust owns 100% of the LLC, and the LLC holds the actual bank accounts, brokerage accounts, and investments. This LLC layer is what gives the settlor day-to-day operational control: the settlor is appointed as manager, which means they make investment decisions, move money, and run the accounts in ordinary circumstances, while the trust’s protective authority sits dormant until it’s genuinely needed.
Transferring an existing LLC’s membership interests to the Cook Islands Trust is one of the most common ways to fund a structure for a settlor who already uses LLCs to hold business interests, real estate, or investment portfolios. The key thing to understand is what actually moves — and what doesn’t.
What Actually Transfers — and What Stays
When LLC membership interests transfer to the trust, the LLC’s underlying assets don’t move. The bank account the LLC holds stays in the LLC’s name. The investment portfolio stays in the LLC’s name. The property or business interest the LLC owns stays exactly where it is. Only ownership of the LLC itself changes — from the settlor personally holding the membership interest, to the trust holding it instead.
This is a structural distinction that matters enormously for understanding what protection actually changes. Before the transfer, a judgment creditor who pierces or reaches past the LLC can potentially get at the settlor’s personal interest in the LLC’s assets. After the transfer, the LLC’s membership interest is held by the Cook Islands Trust, which is held by a trustee outside US court jurisdiction. The path from a US court judgment to the assets inside the LLC now runs through the offshore trustee rather than directly from the settlor’s personal ownership.
The Transfer Mechanics
Transferring LLC membership interests to a Cook Islands Trust involves two core documents: an assignment of membership interests, which formally transfers the interest from the settlor to the trust (or to the trustee on behalf of the trust), and an amended operating agreement, which reflects the new ownership and typically updates the management provisions to confirm the settlor’s continued role as manager despite no longer holding the membership interest personally.
Where the LLC has co-members, their consent or at least their notification may be required depending on the operating agreement’s transfer restrictions — most operating agreements include provisions that restrict or require consent for membership interest transfers, and these need to be reviewed before any assignment is executed. The transfer doesn’t change the LLC’s tax classification or require a new EIN; it changes ownership at the entity level without restructuring the LLC itself.
Domestic vs. Offshore LLCs in the Structure
A settlor can transfer the interests of a domestic LLC to the Cook Islands Trust — the LLC stays domestic and continues operating exactly as before, with only its ownership changing to the trust. This is common for LLCs holding real estate or business interests that need to stay domestically structured.
The underlying LLC in the standard Cook Islands Trust structure — the one holding the offshore bank and brokerage accounts — is typically a Nevis or Cook Islands LLC rather than a domestic one. An offshore LLC adds the additional protection of Nevis or Cook Islands law, including Nevis’s charging-order-only creditor remedy and the mandatory creditor bond, on top of the trust’s own protections. For the purely operational layer holding liquid financial assets, an offshore LLC in a jurisdiction with its own strong creditor barriers is the stronger choice. See our guide to Cook Islands Trust with Nevis LLC for how this combination works in practice.
Tax Treatment of LLC Interest Transfers
For a Cook Islands Trust treated as a foreign grantor trust — which is the standard treatment for a US settlor — the transfer of LLC membership interests to the trust is generally not a taxable event. The trust is treated as the same taxpayer as the settlor for income tax purposes, so a transfer from the settlor personally to their own grantor trust doesn’t constitute a sale or exchange that would trigger recognition of gain or loss.
This applies to the transfer of the membership interest itself. It doesn’t change how income generated by the LLC is taxed — that continues to flow through to the settlor’s personal return in exactly the same way it did before. The transfer changes ownership structure, not tax treatment of income.
