Executor
Last updated 17 July 2026
An executor is the person or institution appointed in a will to administer the deceased's estate. The role covers gathering in the assets, paying debts, expenses, and taxes, and distributing what remains to the beneficiaries according to the will. In many jurisdictions the executor must first obtain formal authority from a court or probate registry before dealing with the estate's assets, and throughout the process the executor acts as a fiduciary, obliged to serve the interests of the estate and its beneficiaries rather than their own.
Executors can be family members, trusted advisers, professionals such as lawyers or accountants, or corporate institutions like trust companies. Many families appoint more than one, pairing a family member who knows the people with a professional who knows the process.
Why it matters for family offices
For wealth-owning families, the choice of executor is a key estate planning decision, because complex estates are hard to administer well. An estate that spans operating companies, fund interests, properties in several countries, art, and layered holding structures demands an executor who can navigate valuations, illiquid assets, and multiple sets of advisers, and who is impartial enough to hold the confidence of all beneficiaries. An executor's work is also only as good as the records available: without a current picture of what exists and where it is held, administration stalls.
How it shows up in practice
When the head of a family dies, the executor's first task is building a complete inventory of the estate. In practice, this is where the family office comes in. A well-run office can hand the executor an up-to-date net worth statement, an entity organisation chart, custodian and bank account lists, outstanding capital commitments to private funds, and title documents for properties and collectibles. With that foundation, the executor can move quickly to valuations, tax filings, and distributions. Without it, the same estate can take years to piece together from old statements and correspondence. Families that keep consolidated, current records are, in effect, doing much of the executor's hardest work in advance, and sparing the next generation a long and expensive reconstruction at the worst possible time.
Related terms
Will
A legal document directing how a person's assets are distributed at death and, where relevant, who will care for minor children. For UHNW individuals, the will works alongside trusts and entity structures, often functioning as a backstop that pours remaining assets into trusts. Dying without a valid will leaves distribution to statutory default rules, an outcome no wealthy family intends.
Estate Planning
The legal and financial arrangement of a person's assets to ensure they are transferred according to their wishes, with minimal tax friction and family conflict. Tools include wills, trusts, holding structures, and lifetime gifting strategies. For UHNW families, estate planning is a continuous discipline that must keep pace with changing laws, asset values, and family circumstances.
Trustee
The individual or institution legally responsible for holding and managing trust assets in the best interests of the beneficiaries. Trustees owe fiduciary duties of loyalty and care, and their decisions are governed by the trust deed. Families often combine professional trustees with trusted advisers or family members to balance expertise and family insight.
Beneficiary
A person or entity entitled to receive benefits, such as income, capital, or discretionary distributions, from a trust, estate, insurance policy, or foundation. In family wealth structures, beneficiaries are usually family members across multiple generations. Understanding who benefits from which entity is essential for accurate consolidated reporting of family wealth.
Codicil
A legal supplement that amends specific provisions of an existing will without rewriting the whole document. Codicils are commonly used for targeted changes, such as updating an executor or exercising a testamentary power of appointment. They must be executed with the same formalities as the will itself to be valid.
