A brokerage account held by a US custodian is fully within the reach of a US court. A judgment creditor can serve a garnishment order on the broker, who is a US entity subject to US court authority, and the account can be frozen or seized without ever going to a foreign court or confronting any of the barriers a Cook Islands Trust otherwise places between the creditor and the assets.
Moving that same portfolio into an offshore custodial account held in the name of the underlying LLC — which is owned by the Cook Islands Trust — changes the picture entirely. The LLC is not a US entity. Its accounts are held at an offshore institution outside US court jurisdiction. A judgment creditor who wants to reach those assets now has to bring an entirely new claim in the Cook Islands, prove the original transfer was fraudulent beyond a reasonable doubt, do it within the Cook Islands’ one-to-two-year statute of limitations, and pay for offshore counsel throughout. Most creditors faced with that prospect settle or walk away before they ever try.
Securities can move into the offshore structure two ways: in-kind, meaning the positions transfer from the domestic brokerage account to the offshore custodial account without being sold, or through liquidation, where the domestic portfolio is sold, the cash proceeds are wired offshore, and the positions are repurchased at the offshore custodian.
In-kind transfers are generally preferable when cost basis matters. Selling a portfolio with significant embedded gains triggers a capital gains tax event in the year of the sale — the same gains that would have been deferred indefinitely if the positions had simply been held. Transferring in-kind avoids that realisation entirely, preserving the original cost basis in the same positions now held at the offshore custodian.
The catch is custodian compatibility. Not every offshore institution can receive and hold every security. US-listed equities are widely available at major offshore custodians, but less liquid positions, certain ETFs, or alternative investments may not transfer cleanly to every offshore option. Checking the receiving institution’s custody capabilities against the actual portfolio before initiating the transfer avoids a forced liquidation the settlor didn’t intend.
The most commonly used offshore custodians for Cook Islands Trust structures are Swiss private banks, Singapore-based institutional custodians, and Cook Islands banking institutions — each with different minimum account sizes, investment universes, and fee structures. Swiss private banks tend to have the broadest securities coverage and the deepest institutional infrastructure, but higher minimums and more demanding onboarding. Singapore custodians offer strong technology and a wide Asian equity universe alongside US-listed securities. The Cook Islands’ own banking institutions — particularly Capital Security Bank — offer the tightest integration with the trust structure given their specific focus on the Cook Islands international financial services market.
In practice, the trustee’s existing banking and custodial relationships are the most efficient starting point, since the institution has already completed due diligence on the trustee as a counterparty. Opening at a new institution from scratch adds several additional weeks to the process and involves parallel compliance reviews.
Once the portfolio sits in the offshore custodial account held by the LLC, the settlor — as manager of the LLC — retains full day-to-day investment authority. Buying and selling securities, rebalancing the portfolio, and making tactical allocation decisions all remain within the settlor’s direct control as LLC manager, without requiring trustee involvement in routine decisions. The trustee oversees the structure and can step in under the duress clause if a genuine legal threat activates that authority, but it does not direct investment decisions in ordinary circumstances.
This arrangement means the offshore structure doesn’t change how the portfolio is managed in any meaningful way during normal operation — the settlor continues to make investment decisions through the same channels they would if the account were domestic, just accessing an offshore account rather than a domestic one.
