Family office due diligence: protecting the principal

A family office does not simply ask whether a counterparty is solvent. It asks whether the counterparty is what it claims to be, whether the assets presented have a demonstrable origin, and whether the relationship will withstand the scrutiny of a bank, a regulator or an heir ten years from now.

Due diligence in this setting is therefore not a compliance step appended at the end of a process. It is a function of asset and reputational protection, exercised discreetly and over a long horizon. It concerns three distinct objects, which are often conflated.

Three objects, not one

The first is the principal: their history, how the wealth was built, the jurisdictions in which it was built, and any exposure to sanctions or political office. The second is the set of entities holding that wealth, with their officers, their beneficial owners and their real substance. The third is the ecosystem of counterparties: managers, intermediaries, introducers, real estate brokers, art dealers, local advisers.

Each calls for different checks. Merging the three produces bulky reports that answer no precise question, and blind spots exactly where risk sits.

Source of wealth: document it, do not moralise

The question of source of funds is not curiosity. It is the question a bank will ask when opening an account, a regulator during an inspection, and a purchaser during a sale. Better to answer it now, documents in hand, than under time pressure later.

The work is to reconstruct a coherent chronology: sectors, disposals, distributions, property, successions. The most frequent inconsistencies are not matters of illegality but of family narrative — an embellished succession, a forgotten founding capital, an activity conducted in a country where records are thin. Identified early, they can be corrected; surfacing before a third party, they become problems.

Three points deserve particular attention.

• Jurisdictions where documentation is structurally weak.
• Periods of tax regularisation.
• Structures whose beneficial owner cannot be identified from the first register consulted.

Entities and their officers

A holding structure is read in layers. The top companies, the intermediate holdings, the trusts and foundations must be identified, and then what each actually contains must be verified: assets, liabilities, litigation, guarantees given to third parties. The warning signs are well known — a professional director shared by hundreds of companies, a registered office used by dozens of entities, minimal capital, changes of officers shortly before a transaction — but they are never proof on their own.

Substance matters as much as form. An entity holding a building with no office, no staff and no verifiable accounts is not necessarily irregular; it is, however, difficult to value, to sell and to defend before a third party. For a trust or a foundation, the governing law, the role of the protector and the class of beneficiaries determine the real extent of powers, and therefore the value of what the family office believes it holds.

Reputation: measure, do not judge

Sanctions and politically exposed person screening produces alerts, most of which are namesakes. The useful work begins after the alert: confirm date of birth, nationality and offices, then cross-check against a second source. An unqualified alert is costly in both directions.

The press deserves the same discipline. A published judgment, an authority’s notice and an article recycled across outlets do not carry the same weight. Allegation, charge, judgment, appeal and expungement must be distinguished. That hierarchy, often skipped, is what allows a report to be used by a board without exposing it to rebuttal.

Some elements are not found online. A site visit, an interview with local counsel, a check at a cantonal or US state registry sometimes yields more than an expensive database.

Discretion and governance of the report

Discretion is not the absence of a record; it is control over circulation. A family office due diligence report should have a named recipient, a written scope and a clear rule on what may be passed to banks or co-investors. The most sensitive conclusions are sometimes spoken in a meeting rather than written down, not to conceal them, but because a document always travels further than intended.

People who are not the subject of the mandate — spouses, children, staff — must be treated proportionately, and minors with particular restraint. Finally, due diligence is never final: it is refreshed at set intervals and on events — a new jurisdiction, a new counterparty, a succession, a divorce, a sale.

If you are preparing a long-term family business relationship, an initial confidential consultation will define the scope, the sources and the reporting format suited to your governance. It commits you to nothing. These pages are editorial information and do not constitute legal advice.
