Selling a Family Business: Managing the Process in the Family's Interest
Selling a business is the family's decision. The process that follows lands on a family office already running at capacity. A practical guide to running a disposal, stage by stage, so it serves the family.
Executive summary
- Pre-process health check
Find what a buyer would find, before they do, then fix it or plan how to present it. - Managing exclusivity
Bluntly: don't grant it. If you really must, cap it tightly and keep an option to walk away. - Preparing for due diligence
Run the process with a prepared data room and a single point of coordination, rather than letting it run the office. - The sale agreement and disclosure
Where the deal is really decided and the liabilities are allocated: the family office team need to stay active in the drafting. - Warranty and indemnity insurance
A parallel but important negotiation: it moves the family's warranty exposure to an insurer and frees up escrow, and it is run, not simply bought. - Keeping advisers and fees in check
One conductor holds the commercial thread and keeps the meter honest. - After completion
Escrow, price adjustments, warranty periods and late claims still need managing.
Selling a business is a major decision in the life of a family and its family office. It also requires careful preparation to mitigate the risk of losing control. Once the sale is under way, buyers, lawyers, accountants and bankers all want answers at once, and an unprepared family office becomes a transaction office overnight on top of the usual affairs.
This is the point where the usual costs of selling a business are compounded by the cost of attention and handling. Splitting attention between a major transaction and the family's affairs will probably result in over-reliance on external advisers, slower decisions, or choices rushed to meet a timeline. All three have a direct impact, on the sale price, on the terms and conditions, or on fees, and they quietly work against both the transaction and the family's assets.
Sale preparation and a focus on people protect the family office team's energy and attention as much as the proceeds themselves. This is a guide to running the process so it serves the family, step by step.
Pre-process health check
Start before the buyers do: the work that protects a sale happens before any potential buyer is approached. We call it a health check, and its purpose is to find the issues a buyer will find, before it does.
All businesses carry something sensitive. An unresolved dispute, a contract that depends on a single customer, or a person the business relies on too heavily. The health check does two things. It surfaces these issues early, and it gives time to address them. Where they cannot be fixed, it sets the strategy for how they will be presented and priced in. A problem disclosed on the seller's terms is a footnote. The same problem found in due diligence is a discount.
None of the above will derail a sale, but each sensitive matter discovered late hands the buyer a reason to renegotiate, which is the one thing you want to avoid.
Managing exclusivity, and the clock
Time and momentum are the essence of a successful transaction. The shorter the process, the better.
At some point a preferred buyer will ask for exclusivity. Our general recommendation is to avoid granting it, because it shifts leverage to the buyer and takes the pressure of urgency off them. Ideally, two bidders remain in the race to the very end.
Exclusivity removes the family's main source of pressure: the presence of other bidders. From the moment it is signed, the buyer sets the pace, and time works in their favour. Usually the buyer will ask for extensions, and the seller will accept. While the clock ticks, costs accumulate, other buyers lose interest, and the team becomes reluctant to walk away from a process it has already invested in. This is the natural, and very human, trap of the sunk cost fallacy.
Sometimes there is no other option than to grant exclusivity. The answer then is to cap it. Exclusivity should be tightly defined in length and scope, kept short, with clear conditions and a hard end date. Any extension should be hard to earn. The team monitors the process closely throughout the exclusivity period, and the family keeps the option to reopen it, not just as a threat but as something they are genuinely ready to do, and to do before the other suitors are gone.
Preparing for due diligence
After the initial round of due diligence and bidding, only a few bidders are retained, and detailed due diligence begins. This is where the burden lands hardest on the family office. Requests arrive daily, with each stakeholder wanting documents, explanations and access, usually on the buyer's tempo rather than the family office's.
To keep this under control, three pillars:
- A well-built data room, as complete as possible (more rather than less, even if access is granted gradually), assembled before the process kicks off and strengthened during the health check, so it answers most questions before they are asked.
- A single point of coordination, with daily oversight of the question log and the answers going out, and a clear strategy for how, when and to whom information is released.
- Sensitive information released in stages, to vetted parties, under the right protections.
The family office must run the due diligence process, not the other way around. Handled badly, it undermines the seller's credibility, and with it the deal. It can also become a business interruption that pulls every team member off their actual job, sometimes for months.
The sale agreement and disclosure
The sale and purchase agreement is where the deal is really decided. Price is agreed early and reported widely. The terms that determine what the family really keeps are settled later, in the warranties, the indemnities and the disclosure letter. This is where the past, present and future liabilities of the business being sold are allocated between seller and buyer. It is the most critical part of the process.
While this work belongs to the family's lawyers, and they should lead it, legal drafting and commercial judgement are different things. A warranty that a lawyer accepts as standard may commit the family to a risk it has no reason, or willingness, to carry.
The disclosure letter, which qualifies those warranties, is the family's protection against later claims. It must be complete, and it must be accurate. It is usually drafted by the management team of the business being sold, who alone hold the detailed business knowledge. That puts the family office team and the team being sold in close contact, even though their interests are often not aligned at that moment. The family office team needs to play an active role in the drafting to ensure nothing falls through the cracks.
When Westwick is involved in such a transaction, our role sits beside external counsel. We make sure the commercial reality of the business is reflected in the legal document, that nothing material is left undisclosed, that both teams work hand in hand, and that the family understands what it is signing before it signs.
Warranty and indemnity insurance
On the sale side, warranty and indemnity (W&I) insurance has become a very common tool. It transfers the risk of a breach of warranty from the seller to an insurer. For a family, the appeal is clean: a faster, fuller exit, with less capital tied up in escrow and fewer reasons for the buyer to hold money back.
Insurance can be very expensive, and it should not be automatic. The policy must be negotiated, the warranties must be underwritten, and the exclusions must be understood. A policy that looks comprehensive can still leave the exact risks the family does not wish to retain uncovered. Some risks cannot be insured at all, or only at a price not worth paying, so part of the risk stays with the family, better by choice than by surprise.
This is where context matters more than paperwork. Knowing which warranties to push for, which exclusions to resist, what risk the family is best equipped or content to retain, and how the policy interacts with the agreement is key. Insurance negotiation is a key part of the sale process, not just a product bought at the end of it.
Keeping your advisers aligned, and your fees in check
A sale brings a crowd of professionals to the table. Corporate lawyers, tax advisers, accountants, bankers, insurance brokers. Each is competent. None of them is responsible for the whole project.
That is the gap. Advisers optimise their own part of the deal. Someone has to hold the commercial thread across all of them, and make sure each piece of work serves the family rather than the process.
The process needs a conductor at the table on behalf of the family: someone to weigh multiple threads of information, make daily, sometimes hourly, judgement calls, and above all stay in dialogue with the family. This is often a trusted family adviser, but it can also be a family member or a senior family office team member if their skillset allows. What it cannot be is the merchant banker, the lead lawyer, or any of the working parties. Each of them has a different goal and a job to deliver.
Among those advisers, there are two kinds of professional around a family: those who serve the office, and those who serve the family. A transaction is the moment that distinction becomes expensive.
Fees are part of the same problem. Professional costs on a transaction are large, and typically unmanaged. Hourly meters run without anyone checking them, scopes overlap, and providers end up setting their own remit. In a 2025 Campden Wealth survey, only a quarter of family offices described the service from their external providers as consistently excellent, a measure of the gap between fees paid and the value families feel they receive.
Every fee should be tightly monitored, with hourly rates and detailed billing entries requested and reviewed. We scope the work in advance, hold each adviser to it, challenge anyone in the room who would not add value, and make sure the invoices match the services received. The saving always pays for the conductor's work several times over.
After completion
Completion is usually not the end of the work. Families find themselves facing several situations:
- Money may be held in escrow against future claims.
- Price adjustments, if any, are calculated in the weeks or months after closing, and we find they are often wrong on the first pass.
- Warranty periods run for months or years, and tax warranties usually last until the statutory limitation period.
- Claims can arrive long after everyone considered the deal closed.
These need to be managed so that no unnecessary costs keep running and residual risks stay under control.
The proceeds will also need a home. A liquidity event changes the shape of the family's wealth overnight, and the decisions that follow are as consequential as the sale itself. The sale of a business often reshapes the office itself: its purpose, its role, and its team.
The family decides. We get it done.
Selling a business is one of the few moments where a family cannot afford to get the process wrong. Often their family office team does not have the bandwidth or the skills to handle a major M&A transaction. Often the voice of the family itself, not the family office, goes unheard at the negotiating table. We step in, manage the process, and become, for a time, the voice, the ears and the eyes of the family at the table. We make sure the deal brought to the family is the best one, handled professionally and efficiently, and only in the family's interests.
Selling the business is the family's call. Getting it done is ours.
