FAMILY WEALTH / ORGANIZING THE WORK
When you are the one connecting advisers, chasing approvals and checking deadlines, start by identifying the work you want someone else to take on.
A guide to comparing a dedicated office, a multifamily office and a coordinated adviser team.
Research checked October 18, 2026 · U.S. federal baseline
CURRENT COORDINATION WORK
Start with the work your family needs done and the decisions someone must own. A single-family office, a multifamily office and a coordinated adviser team can each leave gaps. Compare named responsibilities, authority, service exclusions, continuity and total costs before deciding whether to change the structure around your family.
Consider a fictional family whose CPA has just revised a tax estimate. An investment withdrawal and a trust distribution are also being discussed. The investment adviser can raise cash, the trustee can decide whether the distribution is permitted, and the attorney can interpret the governing documents.
Yet no one has confirmed the combined cash calendar, obtained every approval or checked that the completed transactions match the plan. Every professional may be doing the job they accepted. The family is still left to connect their work.
Decide which responsibilities the family will keep, which it will pay someone else to coordinate and whether a broader organization is needed. Describe each assignment clearly enough for the responsible person to accept it.
This guide is written for families often holding about $5 million or more in liquid assets. That is audience context, not a family-office minimum, qualification rule, estate-tax conclusion or regulatory definition. The discussion uses a U.S. federal baseline; advice must reflect the family's facts.

This guide is written for families often holding about $5 million or more in liquid assets. That is audience context, not a qualification line, a family-office minimum, an estate-tax conclusion or a regulatory definition. Family branches, entities, jurisdictions, administrative volume, decision frequency, desired control, willingness to employ staff and ability to fund continuity can matter more than one balance-sheet number. The discussion uses a US federal baseline; state, trust, tax, employment and cross-border questions require advice for the family's facts.
The evidence has limits. Federal rules and official guidance support only the stated legal or regulatory points. Survey results are bounded publisher-reported findings. Form ADV language is a provider's disclosure, not independent proof. The responsibility framework and conditional paths are editorial judgment.
Consider this fictional example. A CPA revises a tax estimate while an investment withdrawal and a trust distribution are being discussed. The investment adviser can raise cash. The trustee can decide whether the distribution is permitted. The attorney can interpret the governing documents. Yet no one has confirmed the combined cash calendar, obtained every approval or checked that the completed transactions match the plan.
Every professional may be doing the job they accepted. The family is left to connect their work.
Before comparing arrangements, identify who currently requests the information, resolves incompatible instructions, obtains approvals, follows deadlines and collects evidence that the work finished. If the answer is a family member, that person is already performing part of the family's operating function, whether or not anyone calls it a family office.
Begin with a result your family needs, rather than a job title or a provider's service menu. In the cash-calendar example, the result is more specific than “tax coordination”: the right people receive the estimate, the funding decision reaches the person authorized to make it, and someone checks what happened.
Then look beyond that single deadline. Investment oversight, tax and estate coordination, reporting and bill payment each contain different assignments. Write down which ones you need and what remains outside the engagement.
For each responsibility, specify the deliverable, timing and entities covered. This list is a way to define your requirements; it is not evidence that an office or adviser has agreed to provide them.
Investment oversight. The result may include family-level objectives, liquidity constraints, an investment policy, review of managers and assets, and a capital-call and withdrawal calendar. Boundary: deciding policy, recommending investments, executing trades, supervising outside managers and reporting held-away assets are different assignments. Ask for the agreement, authority record, conflict disclosures and a sample review output.
Tax and estate coordination. The result is a timetable joining estimates, records, liquidity, legal decisions, signatures, funding and implementation checks. Boundary: tax planning differs from return preparation; estate analysis differs from legal advice and drafting; coordination differs from trustee action. Name the preparer, lawyer, signer, funding party and completion reviewer.
Reporting. The result is a reconciled view of assets, liabilities, cash flow, entity ownership and valuation dates, with estimates and missing feeds identified. Boundary: aggregation is not an audit, an independent valuation, a tax return or automatic investment monitoring. Ask which custodians, entities and outside assets are supported, who corrects discrepancies, and what history can be exported.
Bill payment. The result covers invoice intake, payee verification, approval, release, reconciliation, exception escalation and absence cover. Boundary: preparing an instruction is different from approving it or moving money. Under the federal adviser custody rule, authority to obtain possession of client funds can constitute custody; whether a particular bill-pay design does so is fact-specific (17 CFR 275.206(4)-2). Have qualified counsel or compliance professionals review the actual authority and controls.
Governance. The result includes decision rights, useful meetings, an action record, conflict escalation and a way for family branches to participate. Boundary: facilitating a meeting does not replace powers granted by a trust, company agreement or other governing document. Family consensus may still be different from legal authorization.
Privacy. The result is controlled access, authorized sharing, vendor visibility, an incident contact, offboarding and recoverable records. Boundary: an NDA, family ownership or a promise of discretion is not a security outcome. Covered institutions can have incident-response and service-provider obligations under Regulation S-P, while the NIST Cybersecurity Framework offers voluntary governance guidance; neither proves that one delivery model is safer (SEC Regulation S-P guide; NIST CSF 2.0 guide).
Succession. The result is continuity through family incapacity or death, employee absence or departure, and provider change. Authorized successors must be able to find and use the right records. Boundary: an organizational succession plan does not activate a power of attorney, appoint a trustee or transfer legal ownership.
Accountability. The result is an accepted owner, reviewer, deadline or trigger, completion evidence, and a route for correction. Boundary: process ownership differs from legal liability, fiduciary capacity, insurance coverage and contractual remedies. A meeting chair cannot bind another firm to work it has not accepted.
A name beside a task is not enough. Return to the revised tax estimate: the person calculating the amount, the person authorizing a distribution and the person checking completion may be different.
One person may fill several roles, and authority may be shared. These are responsibilities, not a fixed approval sequence. Naming a coordinator does not grant trustee, legal, tax, trading or money-movement authority.
Ask the receiving professional to accept the handoff, identify the entity and deadline, and state what evidence will close it. That gives you something concrete to compare across arrangements.
Return to the fictional cash calendar. Put five roles beside every material task: the performer does the work; the authority holder makes or approves the decision; the coordinator manages the handoff; the accountable owner follows unresolved work through correction; and the reviewer checks evidence of completion.
One person may fill several roles, and co-trustees or committees may share authority. The point is to make the combination deliberate. Naming a coordinator on a chart does not confer trustee, legal, tax, trading or money-movement authority. The receiving professional should accept the handoff, understand the entity and deadline, and state what evidence will close it. Then test the arrangement with an urgent decision and with the usual lead absent.
Ask a simple sequence: Who calculates? Who decides? Who may act? Who tells the next person? Who checks the result? Who escalates a miss? An external lawyer may still draft documents even when another firm coordinates the estate-planning process. A relationship manager may organize reporting without supervising every asset. Scope, authority and completion are separate facts.
With the responsibilities defined, you can ask how each arrangement would handle them. The distinction is how the work is organized, what someone expressly accepts and what your family must still fund or oversee.
Use the cash calendar as a test. These are possible assignments to negotiate, not services presumed included under a label.
A dedicated organization for one family.
A staff controller could maintain the cash calendar and chase completion, alongside outside specialists.
Hiring, supervision, systems, governance and the cost of backup. Dedicated control requires an organization capable of sustaining it.
A professional team shared across families.
A service lead could coordinate the calendar if the engagement accepts that work.
The legal entity, included services, affiliates, response times, entity coverage, team capacity and who takes over during absence.
Specialists connected by an accepted coordination role.
An existing adviser or administrator could take on a paid integration mandate.
Other firms accepting the handoffs, information requirements and deadlines. Coordination needs capacity, backup and a price.
In each design, the CPA could still calculate the estimate, the trustee retain distribution authority and the investment adviser execute an authorized funding instruction. A separate completion check would confirm what happened.
These are operating models, not interchangeable legal statuses. No label establishes legal eligibility, authority or service quality.
A single-family office (SFO) is a dedicated organization controlled for one family. It can employ staff and retain outside investment managers, lawyers, accountants, security specialists and administrators. A family can tailor the operation, but it also takes on hiring, supervision, systems, vendor oversight, backup and governance.
A multifamily office (MFO) is a shared professional organization serving multiple families. It may offer access to people and systems without requiring the family to employ an entire team. The label does not reveal which legal entity performs each service, what is included, whether an affiliate or subcontractor is involved, or who has authority to act.
A coordinated adviser team keeps specialist relationships and adds an expressly accepted integration role, common information standards and a completion process. The coordinator may be a family member, employee or outside provider. Coordination consumes real time and needs capacity, backup and a price. A collection of advisers continuing in separate silos is the current arrangement, not a coordinated model.
These descriptions are operating models, not interchangeable legal statuses. The federal family-office exclusion turns on serving only family clients, family ownership and control, and not holding out to the public as an investment adviser; it is not a wealth test or service-quality approval (17 CFR 275.202(a)(11)(G)-1). For an investment adviser, fiduciary duties apply within the agreed relationship, and the federal duty cannot simply be waived; adviser status still does not assign every tax, legal or administrative task (SEC Interpretation IA-5248).
Take the same deliverables, frequency, family and entity scope, response expectations and completion standards to every candidate—including your current advisers. A proposal is easier to assess when the work being priced stays the same.
For every required service, ask the provider to state whether it is included, separately priced, referred, excluded or unclear. Keep the assignment marked as proposed until an authorized person or provider accepts it in writing.
Ask about affiliated products and managers, referrals or commissions, lending and cash-sweep incentives, related vendors, staff compensation and layered fees. Those questions help establish what the quoted service actually includes before you compare its cost.
Write a service brief before requesting proposals. Use the same required deliverables, frequency, family and entity scope, response expectations and evidence standards for the current arrangement, an SFO, an MFO and an explicitly coordinated team. Mark every proposed assignment as proposed until an authorized person or provider accepts it in writing. If a proposal combines these arrangements, confirm the same service boundaries and responsibilities.
As an illustration of operating design, an SFO could assign a staff controller to maintain the calendar and chase completion; the family would need to hire, supervise and back up that role. An MFO could assign a service lead if its engagement accepts the work; the family would need to confirm response times, entity coverage and who takes over. A coordinated team could give an existing adviser or administrator a paid integration mandate; the other firms would need to accept the handoffs and information requirements.
In each design, the CPA could still calculate the tax estimate, the trustee retain distribution authority, and the investment adviser execute an authorized funding instruction. A separate completion check would confirm what happened. These are possible assignments to negotiate, not services presumed included under any label. In the current arrangement, first identify who is doing that integration work today and whether they agreed to it.
Public brochures can help explain why the written agreement matters, but they remain provider disclosures rather than proof of delivery. Pathstone's March 2026 brochure describes professional services as agreement-specific and often à la carte, excludes legal advice, and says it may coordinate a client's existing counsel (Pathstone Form ADV). Cresset's March 2026 brochure describes family-office services through an affiliate under an engagement that may carry separate fees (Cresset Form ADV). Colony's February 2026 brochure describes coordination with existing professionals and a separately engaged affiliated trustee (Colony Form ADV). None of those disclosures is an endorsement, a family-specific quote or evidence that every listed service is included.
For every candidate, ask about affiliated products and managers, referral or commission arrangements, lending and cash-sweep incentives, layered fees, related vendors, staff compensation and the incentive to sell more of the coordinator's own services. SEC brochure instructions require advisers to discuss scope, fees, other costs and material conflicts, but a filed brochure is still the provider's disclosure, not an SEC audit or approval (SEC Form ADV Part 2 instructions).
A quoted fee does not tell you the full cost if substantial work is excluded or still falls to the family. Separate continuing charges from the cost of changing arrangements, and reconcile bundled items before adding them.
For example, if a bundle already includes reporting, adding its reporting allocation again overstates the total. The worked example below shows how to reconcile direct charges, embedded expenses and first-year setup without counting the same cost twice.
Unknown is not zero. Keep known, estimated, unknown, contingent and excluded items visible. A higher fee does not establish broader service.
Compare the costs separately: recurring direct charges to providers, employees and vendors; embedded investment expenses; one-time setup, exit and overlap costs; and the family's own oversight time. List unknown, contingent and excluded items beside the known amounts. A missing price is unknown, not zero.
Reconcile fees before adding them. In an illustrative example, a $40,000 bundle includes an $8,000 reporting allocation. An outside CPA costs $12,000 and underlying fund expenses are estimated at $6,000. Direct cost is $52,000; recurring economic cost is $58,000, not $66,000, because the reporting allocation is already inside the bundle. A $5,000 setup charge would make the full-year illustration $63,000. Family time remains separate. These invented numbers are arithmetic teaching aids, not market prices, Altar Rock fees or a client case.
These surveys provide context, but they do not tell a family what a particular arrangement will cost. J.P. Morgan's 2026 survey covered 333 single-family-office clients averaging $1.6 billion in family net worth. In its broad lowest band—offices supervising $250 million or less—the reported average annual operating cost was $875,000, with internal and external categories included. That cohort and measure cannot be projected to a $5 million family or treated as an SFO break-even point (J.P. Morgan 2026 Global Family Office Report). UBS's 2026 survey of 307 family-office clients reported that pure operating costs were 53% of expenditure, but did not publish a current dollar or basis-point benchmark in that cost section (UBS Global Family Office Report 2026). These are provider-sponsored survey findings from very wealthy client groups, not universal population estimates.
An asset-based advisory fee may leave tax preparation, legal drafting, bill payment, separate trust work, custody, underlying managers or private-fund expenses outside the package. Conversely, a higher fee does not prove broader service. Compare all-in ongoing cost and first-year change only after scope, billing base, timing and duplicate entries are reconciled.
Now return to the cash deadline and remove the person who normally keeps everyone connected. The arrangement needs to work when a family coordinator is incapacitated, an employee leaves or a relationship manager changes.
For a dedicated office, examine staffing, supervision and backup. For an MFO, ask about the assigned team's workload, turnover, subcontractors and replacement process. For coordinated advisers, confirm that the other firms accept information and deadline obligations.
No arrangement removes privacy risk. Compare access design, tested recovery, incident roles, vendor visibility and export rights rather than assuming one model is always safer.
Ask what happens when the family coordinator is incapacitated, the lead employee leaves, the relationship manager changes, a provider is acquired, or the next generation wants a different direction. Who can find the decision record, access the data, meet a filing date, authorize a permitted payment and restore a failed system?
Staffing begins with functions, not titles. A dedicated office needs operating leadership, accounting and reporting work, investment oversight, access to specialists, information security and continuity. Those functions may be combined or outsourced, but each combination needs capacity, supervision and backup. Count loaded compensation, payroll and benefits, recruiting, retention, systems, insurance, professional support and family management time. For an MFO, ask about the assigned team's experience, workload, turnover, subcontractors and replacement process. For coordinated advisers, price the integrator and confirm the other firms accept information and deadline obligations.
Ask each candidate to show how succession and backup would work in practice. In J.P. Morgan's 2026 client survey, 86% reported no clear succession plan for family-office decision-makers; this is a bounded survey observation, not a prediction about any family. UBS's 2026 client survey reported an office succession plan among 35% of respondents. The figures use different samples and should prompt questions, not rankings (J.P. Morgan report; UBS report).
No arrangement removes privacy risk. Dedicated staff can limit routine sharing while concentrating knowledge and risk in a few people. Institutional systems can add controls while introducing affiliates and vendors. Multiple advisers create more data copies and handoffs. Compare access design, tested recovery, incident roles, vendor visibility and export rights rather than assuming a universal winner.
A sound long-term choice can still be a difficult immediate move. A coordination pilot, MFO onboarding and an SFO build are different projects. Identify who owns each part of the change and what must keep working while it happens.
Asset sales, gains, transfer restrictions and other contingent consequences need investigation; they are not generic assumed costs. Transition difficulty may change the sequence or timing without changing the family's long-term preference.
Even if an arrangement fits the family long term, misunderstandings about the transition can make it a poor choice now. Inventory contracts, account registrations, trust and entity ownership, reporting history, tax lots, authorities, upcoming deadlines, data exports and illiquid holdings. Determine whether custody or account transfers are actually necessary. A coordination pilot, an MFO onboarding and an SFO build are different projects.
Name who owns onboarding, data cleanup, reconciliation and each permission change. Price recruiting, legal structure and contracts, system configuration, temporary duplicate providers, termination charges, nonrefundable minimums and corrective work. Asset sales, gains, transfer restrictions, fund liquidity and lost fee concessions are contingent consequences; investigate them rather than building them into a generic estimate.
Keep the old and new arrangements running together where continuity requires it, but define the overlap and its cost. Before ending an old service, reconcile opening records, confirm tax lots, scheduled payments and filing deadlines, obtain needed exports, and test that the new team can produce the agreed result. Transition difficulty can change the sequence or timing without changing the family's long-term preference.
The comparison should leave you with a specific account of who does the work, who can authorize it, what it costs and how completion is checked. It should also show what the family has chosen to retain and what is still unresolved.
If specialists cover the work but handoffs fail, investigate an explicit coordination mandate. If recurring operations exceed the family's capacity, look for a provider that demonstrably accepts those tasks. If dedicated control and custom service are essential, assess the organization, governance, staffing, systems and backup an internal office requires.
Test the proposal against an ordinary month, an urgent event and the absence of the usual coordinator. More boxes checked do not establish suitability. Your next discussion should focus on the responsibilities and costs that remain unresolved, and who will accept them.
Prepare a brief you can use to compare proposals. For every required job, record the deliverable, timing, entities covered, performer, legal authority, coordinator, accountable owner, reviewer, backup, accepted handoff, service evidence, exclusion and open question. Add known recurring costs, embedded expenses, first-year setup and overlap, unpriced items, retained family time and transition dependencies.
Do not collapse that evidence into a suitability score. A candidate with more boxes checked may still have the wrong authority, inadequate capacity, material conflicts or an incomplete price. A family may intentionally retain work. The brief should make that choice visible, along with the person who will carry it.
Test the proposed arrangement against an ordinary month, an urgent event involving tax, cash needs and legal decisions, and the absence of the usual coordinator. Identify what could go unfinished in each situation. Then take the same brief to each candidate and require the words included, separately priced, referred, excluded or unclear. Before you choose, confirm who will do the work, who can authorize it, what it will cost and how you will check that it was done. Keep any unresolved costs or responsibilities in the brief.
