In brief
- A wealth manager runs the money. The family keeps the direction and the final decision.
- Ask how the firm is paid before anything else. Fees and product ties tell you where its interest will pull.
- Separate the mandate from the custody. Know who manages the assets and who holds them.
- Judge track record net of fees, against an honest benchmark, and set the exit before you sign.
The hire that quietly shapes a generation
A family hires a wealth manager to look after the part of the fortune held in markets. Choosing well is not glamorous work, and it is often done under time pressure, on a recommendation, with little to compare against. The pitches sound alike. Everyone is independent, everyone is aligned, everyone has a process.
The results tell a different story. Only 25% of families rate their external providers as consistently excellent (Campden Wealth 2025). A wealth manager runs the part of the capital that is meant to compound, so a poor choice costs the family more every year it runs. Choosing well is not complicated. It takes the right questions, asked in the right order, and the discipline to hold to the answers.
What a wealth manager does, and what stays with the family
A wealth manager manages the liquid part of the portfolio. That means building and running an allocation, selecting instruments or funds, executing trades, and reporting on what happened. It is a real and demanding job, and a good one earns its keep.
It is a narrower job than the family sometimes assumes. A wealth manager is a supplier the family hires to run the money, not the voice that helps the family decide what the money is for. Those are two different roles, and confusing them is a common and costly mistake. The family, or the person who helps the family choose its direction, sets the strategy, the risk appetite, and the purpose. The wealth manager works inside that mandate.
This distinction matters because it decides what you are actually buying. The market bears it out. Families outsource execution readily, but the investment decision itself stays close to home: it rests with family members in 42% of offices, with in-house professionals in 27%, and with a committee in 26% (Citibank 2025). Strategic allocation is kept in-house in the large majority of offices. You are hiring a wealth manager to run a plan the family owns, not to own the plan.
Start with how they are paid
Before the reputation, before the performance charts, before anything on the website, ask one question. How does this firm make money from us, and what does it earn from anyone whose products it might recommend?
The answer tells you where the manager's interest will pull when it matters. A firm paid a clear fee on the assets it manages, and nothing else, has a simple incentive: grow the pot and keep the client. A firm that also collects retrocessions from funds, margins on structured products, or a share of what it places has a reason to favour those products over cheaper or better ones. Those payments are rarely put in front of the family. So ask, and ask plainly. What is your management fee and what is the predicted total expense ratio (which should reflect any embedded costs within the structures and vehicles that will be used by the manager)? Do you receive anything from a fund, a bank, or a product provider in connection with our account? Are custody, dealing, and advice all to be provided by the same house?
Fees deserve this scrutiny because they compound against you. A charge that looks small on a fact sheet is a large number over a decade, taken from a base that should have been growing. Put the answers in the contract: a stated fee for a defined mandate, full disclosure of any embedded third-party fees and payments, and the right to see the all-in cost in cash terms each year. A manager who works for the family alone signs these without difficulty.
Separate the mandate from the custody
Two questions sit behind every wealth-management relationship, and families often collapse them into one. Who manages the assets, and who holds them?
The mandate defines how much discretion the manager has. Under a discretionary mandate, the firm makes and executes decisions within agreed limits, and the family reviews after the fact. Under an advisory mandate, the manager proposes and the family approves each move. Discretion buys speed and takes work off the office. It also hands over day-to-day control, so the limits, the reporting, and the review cadence have to be set with care. Neither model is better in the abstract. The right one depends on how much decision making the family wants to retain rather than to delegate.
Custody can remain separate, and keeping it separate provides some additional protection and flexibility. When the firm that manages the money is not the firm that holds it, the family gains an independent record of what it owns and a check on valuations and charges. Assets held across more than one institution give the family room to move a mandate without moving the money, and to compare one manager against another on the same footing.
Judge the track record, and the fit
Performance is the easiest thing to present well and the hardest to read honestly. Ask for returns net of all fees, over a full market cycle, against a benchmark the manager did not choose to flatter itself. A number without a comparison is marketing. A number next to the right index is information.
Look past the returns to how they were made. A manager who can explain the losing years, the positions that went wrong, and what changed afterwards is telling you more than one who shows only the good line. Ask what they run for families of your size and shape, not what they run in aggregate. Then take references, check them for credibility, and call them. The most useful reference is a family that left, and why.
Fit is the quiet criterion that decides whether the relationship lasts. A wealth manager sees the family's balance sheet, its plans, and sometimes its tensions. That access earns trust, and trust travels well. Across the industry it is the second most important reason families choose a provider, named by 58%, behind only the ability to work across jurisdictions (Ocorian 2026). A firm the family cannot speak to plainly is the wrong firm, whatever the numbers say.
Keep control after you sign
Choosing the manager is the start of the work. Keeping control is the rest of it. The family stays in charge through a few habits that cost little and pay for themselves.
Set the reporting you need, not the reporting the firm prefers to send: holdings, performance net of fees, and the all-in cost, on a fixed schedule and in a format the office can consolidate with everything else. Review on a set cadence against the mandate, and treat drift from the agreed risk as a conversation, not a surprise. Keep the option to bring more of the work in-house as the office grows, or to hold it out, and revisit that line as the family changes. The decision of what to run yourself and what to hand out is not settled once and one time only. Families that share a single manager as part of a wider platform face this most sharply, and the difference between a single and a multi-family office often turns on exactly this question of control.
Above all, write the exit into the start. A clear scope, no lock-in, no exit penalty, and a contract the family can end in a matter of days. A manager confident in the value it adds has no reason to resist. Resistance here is itself an answer.
The family decides, the manager runs the money
A wealth manager is one of the most consequential suppliers a family will ever hire, and one of the easiest to choose badly. The criteria that hold are unglamorous: understand the economics, separate the mandate from the custody, read the track record honestly, and keep the exit open. Do that, and the money is run by a firm that answers to the family. The direction, as it should, stays where it belongs.
