What is a family office in plain English?
In plain English, a family office is the back office and the decision desk of a wealthy family. It tracks assets, pays bills, coordinates lawyers and accountants, reports on investments and prepares family decisions. Banks, lawyers and managers each see one slice, while the office sees the whole picture. The family office definition page covers the exact wording and the edges of the term.
Size varies widely. Some offices hold 2 or 3 people, others a full team of specialists. What they share is a purpose: give the family one consolidated view and one trusted route for every decision. Singapore hosts such teams close to banks, advisers and fund managers, and Asian capitals sit a short flight away.
What is a single family office and who runs it?
A single family office serves one family only. The family owns it, pays for it and sets its priorities, so the whole team works toward one set of goals. The guide on how one family runs its own office explains the structure, the owner’s role and the moment when a family decides to start one.
Control is the main benefit. The family picks the people, the reporting style and the level of privacy. In return the family carries payroll, systems and compliance duties, which suits larger and more complex estates. Smaller estates often reach the same coordination through a shared or outsourced model.
How does a multi-family office serve several families?
A multi-family office is one firm that serves several families with a shared team, shared systems and shared research. Each family gets reporting, investment support and coordination, and the cost of the platform is split across clients. The multi-family office page explains how these firms organise their teams and what a family can expect from one.
The model gives a family access to specialists it could not hire alone: a tax lead, a reporting analyst, a risk officer. The trade-off is attention. Your family shares time with others, so clear service levels and a named contact matter. Those details deserve a written agreement before you sign.
How do single and multi-family offices compare for a family?
Both models coordinate wealth, and they differ on control, cost structure and speed. A single office offers full control and a private team, while a shared office offers a faster start and a broader bench. The page on single family office vs multi-family office sets the trade-offs side by side with criteria you can score.
Families often move along a path. Many begin with a shared provider, learn what they need, and later build a private team once the estate and the workload justify it. Others keep a hybrid for years. The right answer follows the size of the estate, the number of jurisdictions and the appetite for managing people.
What is a virtual family office and when does it fit?
A virtual family office has no large in-house team. A coordinator, often one person, engages outside specialists for legal, tax, accounting and investment work and keeps the family picture in one place. The virtual family office guide explains the coordinator role and the tools that connect the providers.
This model fits families that want coordination without a payroll. It works best when the estate is complex enough to need several advisers and modest enough that a full team stays idle part of the year. Clear reporting rules keep every outside provider working from the same facts.
Why do families pair a family office with a private bank?
A private bank manages accounts, lends and offers investment products inside its own platform. A family office sits on the family side of the table and works across all institutions. It can hold the bank, the lawyer and the fund manager to the same standard. The guide on family office vs private bank compares who does what.
Many families use both. The bank provides custody, credit and execution, while the office provides the overview, the reporting and the questions that challenge each proposal. That separation helps the family compare offers with a clear head, because the person reviewing a product does not sell it.
Which services does a family office cover for a family?
Services fall into 5 groups: investment oversight, reporting and bookkeeping, tax and legal coordination, family governance and lifestyle support. A given office covers some groups fully and others lightly. The page on family office services lists each function and shows who in the team usually owns it.
The mix reflects the family. A founder with a company may need succession and governance first, while a family with a large portfolio may need consolidated reporting. Writing the list of functions before choosing a model keeps the discussion concrete and makes provider proposals easier to compare.
Which staff does a family office employ and when does wealth justify one?
A family office employs investment professionals, accountants, legal and tax coordinators, and administrators. The family office jobs in Singapore page maps these roles, the skills they need and the career paths between them. Reading it helps a family see what it would hire and helps a candidate see what the work involves.
Wealth level shapes the answer. The label ultra high net worth marks the group of families for whom a dedicated office usually makes sense, and the guide explains who qualifies and why the threshold matters. Families below it can still use shared and virtual models for part of the same functions.
How can a family check which family office model fits?
Start with 3 questions: which functions does the family need, how many jurisdictions hold its assets, and how much management time can the family give? Your answers point toward a single, shared or virtual model. The Family office Singapore hub places each model in the wider decision, from setup to succession.
To test a specific choice, the EQOS Asia pricing page lists formats that score a decision across 9 life dimensions. A free 30-minute pre-diagnostic tells you which format fits (EQOS Asia private page, 2026). You can book it through the contact page and bring your own questions.
Frequently asked questions
What does a family office do?
A family office coordinates the wealth, records and decisions of a wealthy family. It consolidates reporting across banks, supervises investments, works with tax and legal advisers, supports family governance and handles administration. The goal is one clear picture and one trusted route for decisions, so the family acts on complete information.
Is a family office only for the very rich?
Dedicated single family offices usually suit large estates, because the team and systems carry fixed costs. Smaller estates can use multi-family or virtual models, which share those costs. The right level depends on the number of assets, jurisdictions and decisions, and a screening call helps a family place itself.
How is a family office different from a wealth manager?
A wealth manager typically focuses on investing a portfolio. A family office has a wider scope: reporting, tax and legal coordination, governance, succession and administration across all institutions. Many families use a wealth manager inside a family office structure, so each role stays clear.
Why do families choose Singapore for a family office?
Families look at Singapore for its legal system, its banks and advisers, and its place in Asian networks, as of October 2026. Specific tax and licensing conditions change over time, so each family confirms them on official pages or with a qualified adviser before deciding.
