An offshore trust is an irrevocable trust formed under the law of a foreign jurisdiction, most often the Cook Islands or Nevis, that places assets under a legal system a US court cannot directly compel, so a creditor who wins a US judgment must relitigate the claim abroad under foreign rules.
In plain terms
A US court can order a person to pay, but it has no authority over a trustee licensed in Rarotonga. That jurisdictional gap — not secrecy — is the actual product. A creditor who beats the settlor in a US courtroom still has to file a fresh case in the foreign court, prove fraud under that country’s own, often stricter, standard, and do it before a short local statute of limitations runs out.
How it works
The settlor transfers assets — typically cash, securities, or an interest in a US LLC — to a trust administered by a licensed offshore trustee, governed by the trust’s chosen foreign law. Many of these trusts include a duress clause: if a US court or the settlor’s own agent is compelled to instruct the trustee to hand over assets, the clause instructs the trustee to disregard that instruction or replace a US-based co-trustee automatically, so no one inside US jurisdiction retains the power the court is trying to reach.
None of this changes US tax treatment. A trust settled by a US person for that person’s own benefit is almost always a grantor trust, taxed to the settlor exactly as if the assets were still in their own name, and the settlor (or any US beneficiary) must file Form 3520 reporting the transfer and Form 3520-A reporting the trust’s activity every year the trust exists — regardless of where the trustee sits.
The numbers
- Cook Islands fraudulent-transfer window: roughly 1 year from the transfer, or 2 years from when a creditor could reasonably have discovered it, after which the transfer generally cannot be challenged in a Cook Islands court.
- Form 3520 penalty: the greater of $10,000 or 35% of the value transferred, for failing to timely report the creation of or a transfer to a foreign trust.
- Form 3520-A penalty: the greater of $10,000 or 5% of the trust’s assets treated as owned by the US person, for a late or missing annual filing.
- US foreign-gift reporting threshold: transfers or distributions from a foreign trust to a US person generally must be reported once they exceed $100,000 in a year.
What people get wrong
That an offshore trust makes the settlor’s assets disappear from a US court’s reach entirely. It doesn’t — it just moves the fight. When Michael and Denyse Anderson refused a court order to repatriate assets from their Cook Islands trust in FTC v. Affordable Media, the Ninth Circuit held them in contempt of court and jailed them, reasoning that as trust protectors they retained enough practical control that their claimed “impossibility” was self-created. US courts increasingly route around the foreign trustee by holding the settlor personally in contempt until the money comes back — which is why the duress clause, not the foreign jurisdiction alone, does most of the actual work.
