Private trust companies: BVI versus Cayman, compared.

A private trust company is a company incorporated for the single purpose of acting as trustee of one trust, or of a defined group of connected trusts, usually settled by one family. Its board — rather than an external trustee's committee — makes distribution, investment and reserved-power decisions.

Families reach for the structure in a small number of recurring situations. A commercial trustee is unwilling to hold a concentrated operating business, a founder-controlled token position or a heavily illiquid portfolio, and will only take the assets subject to conditions the family cannot accept. Trustee fees on a large estate have become disproportionate to the work actually performed. Or succession planning calls for the next generation to sit on a board and learn how the structure works before they inherit responsibility for it.

What a PTC is not is a way to retain beneficial control while appearing to have given assets away. If the settlor directs every decision and the board never exercises independent judgement, the trust is exposed to sham and alter-ego arguments in litigation, and to look-through treatment by tax authorities in the countries where the settlor, beneficiaries or directors are resident. The governance built around the PTC is the substance of the arrangement; the incorporation is administrative detail. Structures that fail almost never fail because the wrong jurisdiction was chosen — they fail because nobody ran the board properly.

The BVI permits a company to carry on trust business without a licence where it qualifies as a private trust company under the Financial Services (Exemptions) Regulations. The conditions are specific and each one matters.

The company must not solicit trust business from the public. It must not be remunerated for acting as trustee — it can be reimbursed for costs, and the professionals it engages are paid normally, but the PTC itself takes no fee for the trustee role. Its trust business must be limited to related trust business, meaning the trusts are connected through a common settlor or through defined family relationships set out in the regulations. Its name must include a designated identifier such as 'PTC' so counterparties can see what they are dealing with.

Critically, the PTC must appoint a BVI registered agent that itself holds a Class I trust licence. That agent maintains the records and must be able to produce them to the BVI Financial Services Commission on request. This is the mechanism by which the BVI supervises an unlicensed trustee: through the licensed professional standing behind it.

Formation is an ordinary BVI Business Company, usually limited by shares or by guarantee. There is no separate application to the FSC and no approval period to wait through, which is why the BVI is generally the faster of the two routes to a functioning entity. The trade-off is that the exemption is self-assessed — if the PTC drifts outside the conditions, for instance by taking on trusts for an unconnected family or by charging a trustee fee, it is carrying on unlicensed trust business, and nobody will have told it so in advance.

Cayman solves the same problem through a registration rather than a pure exemption. Under the Banks and Trust Companies Act and the Private Trust Companies Regulations, a company may act as trustee of connected trusts without a full trust licence provided it registers with the Cayman Islands Monetary Authority as a private trust company.

Registration is a filing rather than a licensing assessment, but it is a filing with a fee, an annual confirmation and a register held by CIMA. The company's activities must be limited to connected trust business, it must not hold itself out to the public as carrying on trust business, and its registered office must be provided by a licensed Cayman trust company that maintains the records.

Where Cayman differs meaningfully from the BVI is remuneration. The Cayman regime does not impose the BVI's unremunerated condition in the same form, which gives more flexibility where a family wants the PTC itself to charge into the structure for governance or transfer-pricing reasons. Cayman also offers the STAR trust as an ownership vehicle for the PTC's shares, and for many advisers that single feature is the deciding factor.

The practical consequence of registration is visibility. A registered Cayman PTC is a known quantity to a bank's compliance team in a way a self-assessed BVI exemption sometimes is not, and that occasionally shortens onboarding with institutions unfamiliar with the structure. It also means an annual compliance cycle that somebody has to own.

The shares of a private trust company cannot sensibly be held by the settlor. Doing so reintroduces exactly the control and estate-inclusion problem the structure exists to solve, and hands any future litigant an obvious argument. They also should not be held by an individual family member, because that creates a probate and succession event at the very top of the structure — the one place a family least wants one.

The standard answer is an orphan vehicle. In Cayman, a STAR trust holds the PTC shares for non-charitable purposes, administered by a licensed trustee with an enforcer appointed to hold that trustee to account. In the BVI, a purpose trust or a VISTA trust performs the equivalent function.

Practitioners generally regard Cayman's STAR regime as the more flexible and better-tested purpose-trust framework, and where the family's governance design is complex — multiple branches, staged succession, enforcer mechanics — that flexibility is worth paying for. The BVI's VISTA regime, by contrast, is the stronger tool where the underlying asset is a family operating company the family intends to keep running without trustee interference: VISTA disapplies the trustee's prudent-investor duty to monitor and intervene in the company's affairs, which is precisely the duty that makes commercial trustees uncomfortable holding a concentrated business.

In practice the jurisdiction choice frequently reduces to which of those two features the family needs more: STAR flexibility above the PTC, or VISTA non-intervention below it. Framing the decision that way resolves it faster than any comparison table of fees.

Both jurisdictions expect the PTC board to be capable of exercising real judgement. A typical board pairs one or two family principals with at least one independent professional director who has genuine trust experience and can document that discretionary decisions were considered rather than rubber-stamped. Some families add a distributions committee, an investment committee, or a protector with reserved consent rights over specified decisions.

Board mechanics matter more than board composition. Minutes should record what was considered, what the beneficiaries' circumstances were, and why the decision was made — not simply that a resolution passed. Meetings should be held where the PTC is supposed to be managed, not wherever the settlor happens to be. These are the details that decide sham arguments years later.

On economic substance, a PTC acting purely as trustee of family trusts is not generally carrying on a relevant activity under either jurisdiction's economic substance legislation. But the analysis depends on what the PTC actually does, and it should be documented on formation and revisited annually rather than assumed once. Where the PTC or the holding companies beneath it conduct financing and leasing, headquarters, distribution or intellectual property activities, substance obligations can attach at that level even where the PTC itself is out of scope.

Both jurisdictions require beneficial-ownership information to be filed with the competent authority. Neither maintains a public register of PTC beneficial owners at the time of writing, but this is an area where policy has moved repeatedly under EU and OECD pressure, and it should be checked at the point of formation rather than taken from an older briefing.

The BVI is normally the cheaper and faster route. There is no regulator registration step, government fees are lower, and ongoing cost is driven mainly by the licensed registered agent, the independent director, and annual accounting and administration. Cayman carries a CIMA registration fee, a higher government fee base, generally higher professional rates, and an annual confirmation that adds a small but real compliance cycle.

Neither jurisdiction is expensive relative to commercial trustee fees on a substantial estate, which is why cost is usually the secondary consideration rather than the deciding one. A family paying a percentage-of-assets trustee fee on a nine-figure estate will recover the entire cost of a PTC structure quickly; a family with a modest estate probably should not be building one at all.

On timing, both jurisdictions are realistically four to eight weeks from complete instructions to a functioning entity. That assumes source-of-wealth documentation, a clean ownership chart, and the purpose-trust deed above the PTC are ready to execute. The variable that actually sets the calendar is diligence on the family and the assets, not the incorporation itself. Any adviser quoting a two-week private trust company is quoting the company formation in isolation and ignoring everything that makes the structure usable.

Budget separately for the things that recur: independent director fees, registered agent or registered office fees, annual accounts, the licensed trustee of the purpose trust above, tax advice in every country where a decision-maker or beneficiary is resident, and periodic legal review when family circumstances change.

This is the part of the exercise most consistently underestimated. A PTC is an unfamiliar counterparty to a relationship manager: an unlicensed company acting as trustee, owned by a purpose trust with no beneficial owner in the conventional sense, holding assets for beneficiaries who are not the account signatories. Onboarding is slower than for an ordinary holding company, and considerably slower where digital assets are in the mix.

Banks and custodians will want the trust deed and any supplemental deeds; the PTC's constitutional documents; a clear structure chart showing the purpose trust above and the underlying holding companies below; identification and source-of-wealth evidence on the settlor and on adult beneficiaries; board minutes evidencing how decisions are actually made; and a written explanation of why the structure exists that does not read as tax-driven.

On jurisdictional reception, Cayman enjoys marginally better recognition with US-facing institutions, fund administrators and prime brokers. The BVI is at least as well received across Asia and the Gulf. Neither carries a meaningful penalty in Europe when the file is properly assembled — what gets files declined is incoherence between the documents, not the two letters on the certificate of incorporation.

The correct sequence is to test banking and custody appetite for the specific asset mix before choosing the jurisdiction, not after the deeds are executed. A structure that cannot be banked in the corridors the family actually uses will need rebuilding, and rebuilding a trust structure is far more disruptive than rebuilding a company.

Choose the BVI when the structure sits over a family operating company or a founder-controlled position the family intends to keep running without trustee second-guessing; when VISTA's disapplication of the duty to intervene is the feature you are buying; when cost efficiency matters; and when the unremunerated condition is a non-issue because the professionals are being paid at the administration level in any event.

Choose Cayman when you need STAR trust flexibility above the PTC; when the family expects institutional counterparties — US private banks, fund administrators, prime brokers — to examine the structure regularly; when the governance design calls for the PTC itself to be remunerated; or when the visibility of CIMA registration is useful in getting compliance teams comfortable.

Where the family is genuinely indifferent on those points, the BVI's lower friction usually wins on cost and speed.

What should never drive the decision is a single adviser's habit, and no jurisdiction choice substitutes for the analysis that precedes it: the asset mix, the beneficiary map, the tax residence of every proposed decision-maker, and real banking appetite. A PTC whose board sits in a high-tax country can pull the whole structure onshore through central management and control. A PTC that cannot open an operating account is a filing cabinet. Both failures are avoidable, and both are cheaper to avoid at the scoping stage than to remediate three years in.
