A family office merits consideration when investment, administrative and family responsibilities require sustained coordination that the current arrangement does not provide. Multiple generations, an operating business, complex holdings or a heavy administrative burden can make that assignment larger. They do not automatically justify a dedicated team. Compare the work, the control the family wants and the cost of several possible arrangements. Campden Wealth/RBC's 2026 report explicitly rejects a fixed threshold for who may benefit. 1

Quick self-assessment

Use these prompts to identify work and unresolved responsibility. There is no score or number of boxes that produces a recommendation.

Work and coordination

Family and continuity

Capacity and cost

The complexity prompts reflect matters identified in Campden/RBC's 2026 report and Morgan Lewis's July 2026 practice framework. The checklist is an editorial tool for discussion; it is not a diagnostic test. 1 2

Situations that may justify one

Several households or generations

One investment portfolio can coexist with different spending plans, beneficiaries and decision rights. Identify which work should be shared and which belongs to each household. An office mandate should specify whom it serves and who can authorize decisions, rather than treating “the family” as a single set of instructions. Multi-generational interests, governance and succession are among the complexity factors in the published frameworks. 1 2

An operating business alongside personal wealth

A family may need to distinguish company responsibilities from personal administration. Start by listing which employees, records and external advisers currently serve each purpose. The published research recognizes offices embedded in family businesses as well as independent offices; those arrangements create different questions about control and continuity. 1

Concentrated holdings or a liquidity event

Write down the work that exists before and after the event: maintaining records, coordinating advisers, tracking obligations and updating the family's decision process. Separate a temporary transaction project from continuing administration. A concentrated position alone does not show how many employees or which provider a family needs; the assignment must be established from the actual holdings and responsibilities. Asset complexity, business ownership and differing liquidity needs are relevant considerations in current published frameworks. 1 2

A large administrative burden

The strongest reason to change an arrangement may be the work between professional appointments: assembling information, checking completion and resolving handoffs. A service list should identify who owns these recurring tasks. Campden/RBC's reported family-office functions include accounting, bill pay, human resources, governance, tax and legal work, with different combinations of internal and external delivery. That does not mean every office performs each service itself. 1

Alternatives for a narrower need

Choose the smallest arrangement that can take clear responsibility for the required work. Adding an organization without removing an existing gap can leave the family with another relationship to supervise.

Main need Alternative to examine first What to establish
Portfolio advice or management
A defined investment-advisory mandate.
Investment authority, reporting, fees and the division of work with tax and legal advisers.
Tax filings or a particular estate project
A scoped engagement with the relevant tax or legal professional.
Deliverables, responsible entities, required inputs and who coordinates related decisions.
Bookkeeping, payments and records
An accounting or administrative service, or a finance employee.
Approval limits, controls, reporting and cover when a person is absent.
A gap between otherwise effective advisers
A coordinating role or limited outsourced mandate.
Authority to obtain information, assign follow-up and maintain the complete record.
Banking, credit, custody or trust administration
The appropriate bank, custodian or trust relationship.
The legal entity and responsibilities for each service, including work left outside the institution.
A one-time transition
A project with a defined end and handover.
Which tasks will remain after completion and who will own them.

These are proposed ways to scope a need, not claims that every provider accepts each mandate. Current offerings illustrate the possibilities: J.P. Morgan Private Bank describes banking and trust services alongside support for existing offices, while Tiedemann Advisors separates extended family-office services from investment management in its disclosure. 3 4

Wealth thresholds: what the evidence says

There are three different questions: whether a regulatory exclusion applies, whether a provider will accept an engagement and whether the arrangement is economical for the family. A single dollar figure cannot answer all three.

Threshold or measure Published evidence How to use it
SEC family-office exclusion
Its conditions set no net-worth, investable-assets or assets-under-management minimum. 5
Keep legal qualification separate from affordability and commercial eligibility. The exclusion has other specific conditions.
Dedicated single-family-office economics
Campden/RBC's September 2026 report gives $100M–$250M in private wealth as a working range where a dedicated office may become cost-effective, depending on costs and complexity. The same report says there is no fixed threshold for who may benefit. 1
An attributed planning range, rather than an eligibility rule or a net-worth floor. Consider shared and virtual options too.
A provider's service minimum
Tiedemann Advisors generally requires a $25M account balance for its investment-advisory service, subject to waiver; this does not establish an extended family-office administration minimum. 4
Read the service, asset basis and waiver language. Do not transfer a threshold to another service at the firm.
Family resources
Net worth, liquid funds and the assets counted in a fee base describe different things.
Build the budget from the family's actual resources and the proposed services; a business sale price is not the shareholder's personal proceeds.

The SEC exclusion concerns a company advising defined family clients, with specified ownership and control, that does not hold itself out publicly as an investment adviser. It is not a general definition of every business selling family-office services. 5

For a family with $50 million, the useful next step is to price the work and compare delivery models. The evidence does not support an automatic yes or no from that figure alone. See the cost guide for the measures and expenses to keep separate.

Which model may fit?

This table identifies arrangements to investigate. Each requires a service scope and a workable budget; none follows automatically from a wealth band. The model distinctions draw on Campden/RBC's 2026 taxonomy and the specific bank and adviser disclosures cited above. 1 3 4

Model Ownership and staffing to establish Assignment to examine Cost and control question
Single-family office
A family-owned organization with employees, outside specialists or both.
Dedicated capacity for the family's chosen responsibilities; investment authority set separately.
Will the family fund and supervise an enduring organization, including replacement staff and systems?
Multi-family office
A shared organization; distinguish the firm's ownership from the team assigned to the family.
A specified combination of advice, investment work and administration.
Is the allocation of people and service scope sufficient, and what costs extra?
Outsourced or virtual office
Identify the internal coordinator, external providers and their employing entities.
Selected functions or broader coordination while retaining some existing relationships.
Who owns the gaps between providers, and who signs the specialist contracts?
Private-bank group
Bank and affiliate teams under separate service terms where applicable.
Banking, custody, trust, investment or planning work within the agreed mandate.
Which family responsibilities remain outside the bank, and which fees attach to each service?
Wealth adviser
Advisory-firm staff and any administrative affiliates or external specialists.
A focused investment or planning mandate, with additional work expressly included.
Does the problem require broader operations, or can a narrower engagement cover it?
Operator or chief-of-staff arrangement
Verify who employs the operator, whether the role is dedicated and who supplies support.
Recurring operational coordination with explicit decision and payment limits.
What remains with the principal, who owns the work product and which advisers retain investment responsibility?

Examples of public service descriptions

These alphabetical examples show different descriptions of work, not a shortlist or an assessment of suitability. Public capabilities do not establish contract terms or service quality. All were checked October 19, 2026 under the same research method.

Aspiriant — a dedicated team within a wider firm. Its Exclusive Family Office page describes a dedicated family team and services including tax, trust and estate planning, governance, accounting and reporting. Establish the engagement scope and price directly; the page does not supply a complete family-office fee. 6

WE Family Offices — advice and outside-provider coordination. Its public pages describe investment strategy and oversight, consolidated reporting, governance and work across a family's provider network. Ask which implementation and administrative tasks are accepted in the particular engagement. 7

Questions to discuss with family and advisers

  • Which recurring responsibilities need an owner, and who owns them now?
  • What has gone wrong, been delayed or taken more family time than intended?
  • Which households, entities and generations should the arrangement serve?
  • Which decisions will remain with the family, and who can make them?
  • Which existing advisers should remain, and who will coordinate their work?
  • What continuing budget is sustainable after outside fees and other expenses?
  • Who will supervise employees or hold the provider to the agreed assignment?
  • How will the arrangement continue if the principal, lead employee or provider changes?

Turn the answers into a brief listing tasks, authority, service recipients and exclusions. That gives competing providers the same assignment to price. The services guide can help make the task list precise.

Situations in practice

The following are decision exercises, not reported families or individual recommendations.

After selling a company

Separate the company's transaction value from the resources the principal actually receives. Then divide the work into immediate projects and ongoing responsibilities. If the continuing assignment is investment advice, tax work and bookkeeping, obtain scoped proposals for those needs before deciding to build an office. If several households, entities and advisers need a permanent coordinator, compare that role across an internal hire, a shared firm and an outsourced arrangement.

During an inheritance or generational transition

Establish which services are already performed by trustees, advisers and existing employees before commissioning overlapping work. Discuss whose instructions govern, how different beneficiaries receive information and which decisions require a family process. The practical question is what remains unowned after existing responsibilities are mapped. Governance and generational complexity are recognized considerations in the published frameworks. 1 2

When replacing an office or provider

Describe the problem in operational terms: incomplete reporting, work outside scope, unclear accountability or an arrangement that has become difficult to supervise. Ask what a replacement would take over and how records, authority and contracts would transfer. A change of model is useful only if the new assignment addresses the identified gap.

Frequently asked questions

At what net worth do you need a family office?

There is no single threshold. The SEC exclusion sets no net-worth minimum. Campden/RBC offers a $100 million to $250 million private-wealth working range for dedicated-office economics, with explicit cost and complexity qualifications, while recognizing other models. Those are different kinds of evidence. 1 5

Is $50 million enough?

The figure alone cannot establish the answer. A dedicated office, a shared provider and a limited administrative engagement have different scopes and economics. Define the recurring work and compare proposals; do not treat the SEC exclusion or a published dedicated-office range as a commercial minimum for all services. 1 5

Do I need a family office or a CPA after selling a business?

First identify the assignment. A tax project and ongoing coordination across advisers are different needs. A family-office arrangement can combine internal and external professionals, so forming an office does not remove the need to specify who supplies tax work and who owns the wider administration. Campden/RBC describes both hybrid and outsourced delivery. 1

What are the disadvantages of a dedicated family office?

The family must sustain the organization as well as pay for it: staffing, systems, supervision and continuity all need an owner. Outsourcing selected functions can reduce the internal assignment, while changing which responsibilities sit with outside firms. The balance between control, infrastructure and cost is central to the Campden/RBC and Morgan Lewis frameworks. 1 2

Is a family office only for founders and billionaires?

The relevant questions concern the family, its resources and the work required. Campden/RBC's fit discussion includes different family structures and operating models and explicitly says there is no fixed threshold for who may benefit. A business sale is one possible transition, rather than a qualification for family-office services. 1
