Settlor Retained Powers and the Sham Trust Risk

How much control can a settlor keep before a trust is attacked as a sham? A practical guide to settlor retained powers and sham trust risk.

The most common way an offshore trust fails is not a clever legal attack on its structure. It is the settlor's own behaviour. A family sets up a trust, transfers assets to it, and then continues to treat those assets exactly as before, instructing the trustee, moving money at will, ignoring the fact that the property is no longer theirs. When a creditor, ex-spouse or tax authority looks closely, the trust unravels.

This is the sham trust risk, and it sits at the heart of asset-protection planning. The question every settlor faces is how much control they can sensibly keep, and where retained control tips a valid trust into a sham or, almost as damaging, into the settlor's alter ego.

Understanding settlor retained powers and their limits is essential, because the benefits of a trust, namely asset protection, succession planning and tax efficiency, all depend on the trust being genuine.

What a sham trust actually means

A sham, in trust law, is an arrangement that has the outward appearance of a trust but is not what it purports to be, because the parties never intended the trustee to hold the assets on the stated terms. The classic formulation requires a common intention between the settlor and the trustee that the documents should not create the rights and obligations they appear to, or that the trustee will simply do whatever the settlor says.

If a court finds a sham, the consequences are severe. The trust is treated as never having existed as a genuine trust. The assets are regarded as still belonging to the settlor, available to creditors, divisible on divorce, and taxable in the settlor's hands. Every protection collapses at once.

A related and overlooked danger is the alter ego or nominee finding, common in some jurisdictions, where even a validly created trust is disregarded because the settlor in practice controls it so completely that the trustee is a mere puppet. The label differs; the destruction is the same.

Why retaining some power is legitimate

It would be wrong to conclude that the settlor must surrender everything and disappear. Modern trust law in the leading offshore jurisdictions expressly permits a settlor to reserve certain powers by statute without invalidating the trust. These statutory provisions exist precisely because total abdication is unrealistic and unnecessary.

Powers commonly permitted by statute include the power to revoke or amend the trust, to direct or veto investment decisions, to appoint and remove trustees, to add or exclude beneficiaries, and to give binding directions on specified matters. Where the relevant statute authorises a reserved power, exercising it does not, of itself, make the trust a sham.

The settlor may also influence the trust through legitimate, non-binding means, above all a letter of wishes that guides but does not bind the trustee. A protector, often a trusted adviser or family member, can hold reserved powers as a buffer between settlor and trustee.

The key word is calibration. The structure must keep the settlor's influence within the bounds the chosen law allows and, crucially, the settlor must then actually behave consistently with the trust being real.

The behaviours that create real danger

In practice, sham and alter-ego findings turn less on the deed than on conduct. The patterns that get trusts attacked are remarkably consistent.

Treating trust assets as a personal piggy bank, with the settlor moving money in and out at will for personal use without trustee deliberation, is fatal. So is the trustee rubber-stamping every settlor instruction without exercising independent judgement, which suggests there was never any intention that the trustee would truly decide.

A letter of wishes that reads as a command, or side correspondence showing the settlor dictating outcomes, is powerful evidence against the trust. Backdated documents, sloppy records, or a deed signed years after the assets were really being treated as the trust's are all red flags. So too is a settlor who tells third parties, banks, business partners, even family, that the assets are still theirs.

Timing compounds the problem. Establishing or funding a trust when a claim is already foreseeable invites not only sham arguments but fraudulent-transfer challenges, an overlapping but distinct line of attack.

How to keep a trust genuinely robust

The discipline that protects a trust is, fortunately, straightforward to describe even if it requires real commitment to follow.

Choose a genuine, professional trustee and let them act like one. The trustee should deliberate, keep minutes, ask questions, and occasionally decline or modify a request. A trustee that always says yes is a liability; a trustee that demonstrably exercises judgement is the trust's best defence.

Keep reserved powers within statute and use them sparingly. Where the settlor holds, say, an investment-direction power, it should be exercised formally and within its terms, not as a backdoor to running the assets personally.

Respect the separation in everyday behaviour. Once assets are in trust, they are the trustee's to administer. Distributions are requested, considered and documented, not simply taken. The settlor should not commingle trust assets with personal ones or describe them as their own.

Get the timing and the paperwork right. Establish and fund the trust well before any storm is visible, execute documents contemporaneously, and maintain clean records. Use a properly drafted letter of wishes that advises rather than instructs.

Match the structure to the law and the family's real residence. Reserved-powers statutes vary, and a settlor's home country may have anti-avoidance rules that look through the trust regardless. The plan must be built with all of those in view.

How HPT helps

We design trust structures that give families appropriate, lawful influence without crossing into the conduct that gets trusts struck down, working with independent professional trustees who genuinely exercise their role and with counsel in the governing jurisdiction. Just as importantly, we advise on the behaviour and governance that keep a trust defensible long after it is signed.

If you want a trust that will hold up when it is tested, rather than one that only looks the part, we would welcome a confidential discussion.
