Cook Islands Trust vs. Panama Foundation

A Cook Islands trust and a Panama Private Interest Foundation are built on different legal traditions and serve different purposes. The Cook Islands trust is a common law trust governed by the Cook Islands trust statute (the International Trusts Act 1984). A Panama foundation is a civil law entity governed by Panama Law 25 of 1995.

For a U.S. person weighing the two structures for asset protection, the Cook Islands trust is the stronger one. The Cook Islands statute dates to 1984 and makes a creditor prove fraud to a criminal standard, and creditors have been testing it in contested litigation since the late 1990s. Panama’s Law 25 was written for estate planning, privacy, and asset management inside a civil law system.

What Is a Panama Private Interest Foundation?

A Panama Private Interest Foundation is a separate legal entity created under Law 25 of 1995. Once the charter is registered, the foundation can own property, sign contracts, and sue or be sued in its own name. It is not a trust, not a corporation, and not a partnership. Panama adapted the concept from the private foundations of Liechtenstein and other civil law countries.

A foundation has a founder, who plays the role a settlor plays in a trust, and a foundation council, which does the work of a trustee or a board. Beneficiaries take from the foundation, and the charter can add a protector to supervise the council.

The founder creates the foundation by signing a charter and registering it at Panama’s Public Registry. The charter names the council members and states what the foundation is for. Beneficiaries and distribution rules sit in a separate private document, the regulations, which is never registered.

Property moved into the foundation belongs to the foundation, not to the founder. The council administers it under the charter and the regulations. The founder can retain control through the charter’s terms, a seat on the council, or the power to appoint and remove the protector.

Forming a Panama foundation takes three things:

• Initial capital of $10,000. The founder pledges it when the foundation is formed and transfers it afterward, so nothing has to be paid in before the foundation exists.
• The word “Foundation” in the name. Law 25 requires it so the entity is not mistaken for a person or a company.
• A resident agent in Panama. The agent must be a Panamanian lawyer or law firm, and countersigns the charter before it is registered.

Panama charges a foundation one annual government fee: $350 for the first year and $400 for every year after.

How U.S. Courts Treat Trusts and Foundations

Cook Islands trusts operate under common law trust principles that U.S. courts have applied for centuries. An American judge already knows what a trust is, what a trustee owes the beneficiaries, and when a creditor can reach trust property. The Cook Islands statute adds protections a U.S. judge has never applied, but the structure itself raises no threshold question about what kind of thing it is.

Panama foundations have no analog in U.S. law, and only a handful of American decisions have engaged with one. The leading decision came in 2026, when the Iowa Supreme Court held over a three-justice dissent that a Panamanian foundation is a different legal creature from a revocable trust. In that case, In re Estate of Ibeling, No. 24-1139 (Iowa May 1, 2026), the assets the founder had moved into the foundation stayed outside his widow’s elective share.

A federal bankruptcy court in Florida allowed a trustee’s alter-ego claim against a Panamanian foundation to proceed in In re Ortega, 562 B.R. 538 (Bankr. S.D. Fla. 2016). Beyond that, no U.S. court has decided whether a creditor can reach a foundation as the founder’s alter ego, how a transfer into one is analyzed as a fraudulent transfer, or how a U.S. judgment is enforced against it.

A creditor attacking a Panama foundation has almost nothing to build on, which makes the attack expensive and the outcome hard to predict. The founder defending one is in the same position, and the result turns on how a single judge decides to characterize an entity U.S. law has no category for.

How Do the Asset Protection Statutes Compare?

Cook Islands trust law asks more of a creditor than Panama’s Law 25 does at every step: a higher standard of proof, a shorter deadline, and a forum the creditor has to travel to. Section 13B of the Cook Islands trust statute requires the creditor to prove, beyond reasonable doubt, that the settlor transferred the assets intending to defraud that particular creditor. The creditor must also prove that the transfer left the settlor unable to pay that creditor’s claim.

Any challenge must be filed in the Cook Islands within two years of the transfer. A creditor who had not already sued the settlor must also have sued on the underlying claim within one year of the transfer. Cook Islands law bars its courts from enforcing a foreign judgment to the extent the judgment rests on law that conflicts with the Cook Islands trust statute. A U.S. creditor holding a judgment therefore has to prove the whole case again in the Cook Islands, under Cook Islands law.

Panama’s Law 25 protects foundation assets from the founder’s personal creditors, but on lighter terms. Under Article 11, foundation assets form an estate separate from the founder’s personal property, and they cannot be seized for the personal obligations of the founder or the beneficiaries.

Article 15 gives a creditor three years from the date of the transfer to challenge a contribution to the foundation as a fraud on creditors. Law 25 sets no heightened standard of proof, so a Panamanian judge applies the ordinary civil standard that governs any other claim.

The Cook Islands imposes a criminal-law proof standard within a two-year window. Panama imposes a civil proof standard within a three-year window. Panama’s foundation law contains nothing that blocks a foreign judgment. A creditor can petition Panama’s Supreme Court to recognize a U.S. judgment, and reciprocity between the two countries is presumed rather than something the creditor has to prove.

Does a Panama Foundation Have Any Litigation Track Record?

Panama foundations have virtually no U.S. litigation history involving contested creditor challenges. The one decision from a state supreme court came out of a probate fight, not a creditor’s collection effort. There is no established body of law addressing how U.S. courts will treat foundations, what theories creditors will use to attack them, or what defenses will succeed.

Cook Islands trusts have been tested in contested creditor challenges in U.S. courts since the late 1990s. Creditors have obtained U.S. judgments, won contempt orders, and spent heavily on enforcement, and they have still failed to reach trust assets. In the decisions where settlors lost, the cause was the settlor’s own conduct: retained control, funding a trust during litigation, or personal spending from trust assets. A settlor choosing a Cook Islands trust today knows what a creditor will try, because creditors have already tried it.

An untested structure gives the founder no more certainty than it gives the creditor. The first case to decide whether a creditor can reach a Panama foundation will set the rule for everyone who built one before it.

U.S. Tax Classification

Cook Islands trusts have a settled place in U.S. tax law. The IRS treats them as foreign trusts, and when the trust is a grantor trust, all of its income lands on the grantor’s Form 1040. The settlor’s accountant handles the annual filings: Forms 3520 and 3520-A, an FBAR, and Form 8938.

Panama foundations create tax classification uncertainty for U.S. persons. The IRS has not issued definitive guidance on whether a Panama foundation is properly classified as a foreign trust, a foreign corporation, or some other entity for U.S. tax purposes. Most practitioners treat them as foreign trusts and file Forms 3520 and 3520-A, but this classification is a professional judgment, not a confirmed IRS position.

If the IRS challenged the trust classification and asserted that a Panama foundation is taxable as a foreign corporation, the tax consequences could change substantially. A foreign corporation classification could trigger Controlled Foreign Corporation (CFC) rules, Passive Foreign Investment Company (PFIC) rules, or other regimes that impose different and potentially more burdensome obligations than foreign trust treatment.

Why Founder Control Weakens Panama’s Asset Protection

Panama’s Law 25 lets the founder keep control that a Cook Islands trust requires the settlor to give up. The founder can sit on the foundation council and appoint or remove its members. The charter can reserve the founder’s right to amend it and to make the final call on distributions. The charter can also give the founder the power to rewrite the private regulations at any time, which is how these documents are usually drafted.

A Cook Islands trust puts legal control in the hands of a licensed trustee. The Cook Islands statute lets the settlor be a beneficiary and keep certain powers, including the power to revoke, but the protection depends on the trustee actually exercising independent judgment. A settlor who keeps too much practical control gives a U.S. court a reason to treat the trust as his own alter ego.

The control Panama allows is what makes the foundation weaker as an asset protection structure. The more the founder keeps, the easier it is for a creditor to argue that the foundation is the founder’s property under another name and that its separate legal personality is a formality.

U.S. courts pierce corporate veils on that reasoning routinely. It is the argument a bankruptcy trustee already made against a Panamanian foundation, and three Iowa justices would have accepted it. They pointed to a founder who was the sole lifetime beneficiary, was his own protector, and could remove the council at will.

Banking and International Acceptance

Banks in Switzerland, Singapore, and other financial centers open accounts for Cook Islands trustees as ordinary business. They know the structure and have account-opening procedures already written for it. The licensed Cook Islands trust companies keep those relationships up as part of routine administration.

Panama foundations have a harder time opening accounts outside Panama. Many banks have never seen a foundation and are unsure what their own compliance rules require of one, and some will not take an entity that fits neither the trust box nor the corporate box. Inside Panama the position reverses: foundations are familiar and accounts are easy to open.

Panama’s years on international money laundering watchlists after the 2016 Panama Papers disclosures are part of the reason. The Financial Action Task Force removed Panama from its increased-monitoring list in October 2023, and the European Union removed Panama from its high-risk list in August 2025, so neither list flags Panama today.

Privacy

Cook Islands trust deeds are not registered anywhere the public can reach them, and the Cook Islands keeps no public registry of trusts. The Cook Islands Financial Supervisory Commission holds regulatory records on licensed trustees, and those are closed to the public as well.

A Panama foundation’s charter is a public document, registered at the Public Registry, and it names the council members, the resident agent, and the foundation’s address. It does not name the beneficiaries. They appear only in the regulations, which are never registered and are not open to anyone outside the foundation. The founder’s own name need not appear at all, because Law 25 allows the foundation to be created through a nominee.

That privacy is narrower than it was. Panama shares financial account information automatically with other participating countries under the Common Reporting Standard, and its first exchanges went out in 2018. Since 2020, a Panamanian resident agent must also report a foundation’s ultimate beneficial owners to a government registry that is closed to the public and open to Panamanian authorities only on a case-specific request.

For a U.S. person, neither structure is private from the U.S. government. A Cook Islands trust and a Panama foundation both go on IRS and FinCEN disclosure forms, whatever the local secrecy rules say.

Cost Comparison

Panama foundations are less expensive to establish and maintain. Formation typically costs $3,000 to $8,000, including legal fees, registered agent fees, and Public Registry filing. Annual maintenance runs approximately $1,500 to $3,000, which pays for government and registered agent fees plus basic administration.

Cook Islands trusts typically cost about $21,000 to establish and about $5,000 annually for trustee administration. Tax compliance adds $2,000 to $3,000 per year for Forms 3520, 3520-A, and related filings handled by the settlor’s CPA.

What the higher Cook Islands figure buys is a licensed institutional trustee under a regulator’s supervision, and tax compliance that is routine because the classification is settled. Panama’s lower figure reflects lighter regulation, less administration, and a creditor-protection record that U.S. courts have barely tested.

Estate Planning and Succession

A Panama foundation keeps its assets out of probate. The foundation owns them, so nothing passes through the founder’s estate when he dies, and the entity keeps operating under its charter.

Article 14 of Law 25 goes further: inheritance laws where the founder or the beneficiaries live cannot be used against the foundation or block it from carrying out its purposes. That provision exists to defeat forced heirship, the rule in most civil law countries that gives children and spouses a fixed statutory share of an estate.

A Cook Islands trust avoids probate on the same principle: the trustee holds the assets, and they pass under the trust deed rather than a will. For a U.S. family, the trust also fits the rest of the estate plan, because the attorney drafting the will and the powers of attorney already works in trust law. Most U.S. estate attorneys have never drafted around a foundation.

When a Panama Foundation Makes Sense

A Panama foundation is the more natural instrument for a person from a civil law country who has never dealt with a trust. Civil law systems are built around entities that own their own property, and a foundation is one. A trust splits legal and beneficial ownership, and that split has no counterpart in the civil law tradition.

Families with assets or businesses in Latin America get practical advantages that have nothing to do with creditors: Panamanian counsel, administration in Spanish, and a legal tradition their own advisors already know. A founder who wants to keep running the assets personally will also prefer the foundation, because Panama lets him hold powers a Cook Islands trustee would have to hold instead.

When a Cook Islands Trust Is the Better Choice

For U.S. persons whose primary objective is asset protection, the Cook Islands trust is the stronger choice across every dimension. A creditor there has to prove fraud beyond a reasonable doubt. The limitation period is two years rather than three. A U.S. judgment buys the creditor nothing without a fresh trial in the Cook Islands.

A founder whose real problem is passing assets to heirs under a civil law regime would be paying a Cook Islands premium for creditor defense the family will never use. Panama’s foundation does that succession work directly, and it costs less.
