Which professionals should you involve in a business transfer?

Updated March 2026 - A successful business transfer does not depend only on finding the right buyer or successor. It also depends on building the right advisory team around the business owner, at the right time and with a clear division of roles. The most common risk is not the absence of advisers altogether. It is bringing the right professional in too late, when the room for manoeuvre has already narrowed and the file has become harder to adjust.

Before choosing an accountant, a lawyer or a notary, you need to identify the exact scope of the deal. A family transfer, a sale of shares, the transfer of a business asset, a donation mechanism or a sale to employees do not raise the same questions. The valuation work, the legal drafting, the family considerations and the timing of the process are not built in the same way.

That is why a transfer should begin with a simple scoping exercise: who are the parties, what is the target date, which assets are included, what already looks sensitive and what still needs to be clarified? The more explicit this starting point is, the more useful each professional becomes.

1. The accountant#

The accountant prepares the numbers, makes profitability easier to read and helps present accounts that can support a valuation discussion. Without that financial groundwork, the conversation about price quickly becomes fragile. The accountant also helps identify exceptional items, clarify recurring margins and prepare the financial story that a buyer, lender or notary will actually read.

In practical terms, the accountant can help:

• clean up the financial présentation before a sale;
• isolate one-off items that distort profitability;
• explain the real structure of revenue and expenses;
• prepare forecasts that are understandable;
• anticipate the questions that will appear during due diligence.

That role is not just technical. It makes the file easier to explain and therefore easier to trust.

2. The lawyer#

The lawyer secures the letter of intent, the protocol, the warranty clauses and the contractual exit mechanics. This is the key adviser for the legal safety of the transaction. Their role becomes even more important when the transaction includes conditions précédent, deferred price elements, post-closing obligations or specific guarantees.

A good lawyer is not only a drafter. They help turn an economic agreement into a legally workable structure and make sure the final documents reflect what the parties actually intended.

3. The notary#

The notary becomes essential as soon as the transfer touches family wealth, property issues, donation mechanics or a broader family succession plan. This is especially true when business shares are being transferred alongside property, family assets or a wider patrimonial reorganisation.

The notary helps align civil, patrimonial and family considerations. In a well-prepared transfer, the notary is not an emergency call at the end of the process. They are part of the early strategic thinking.

4. The valuation or M&A adviser#

This adviser helps position the price, structure the présentation to buyers and organise the negotiation process itself. They are often the professional who keeps the commercial process moving, while also helping the owner decide which discussions are worth pursuing and which should be set aside.

They are useful for:

• building a defendable valuation range;
• preparing the business présentation;
• prioritising potential buyers or successors;
• structuring the negotiation process;
• keeping the project focused on a real transaction instead of scattered conversations.

In practice, the most efficient order is often:

1. the accountant to make the figures reliable; 2. legal counsel to frame the transaction; 3. the notary if family, property or patrimonial issues are involved; 4. a valuation or sale adviser to structure price and process.

This order is not rigid, but it reflects a simple reality: the transaction becomes easier when the financial and legal foundations are ready before the process accelerates. If the structure is still unclear when discussions intensify, the team spends time repairing the file instead of advancing the deal.

Hayot Expertise insight: the better the company is prepared in advance, the less the outcome depends on last-minute negotiation. A transfer is often won six to eighteen months before signature.

The classic mistake is to assign each block to a different professional without any coordination. A successful transfer is an orchestration exercise: figures, legal structuring, tax, patrimonial questions and timing must all connect. If they do not, each adviser may be correct on their own topic while the overall file still becomes difficult to close.

The most common friction points are usually:

• valuation, when the financial reading and the legal structure do not tell the same story;
• warranties, when seller and buyer do not have the same perception of risk;
• timing, when financing, legal drafting and formalities do not progress together.

Good coordination avoids duplicated work, contradictory advice and avoidable delays. It also helps the owner keep a clear picture of what is decided, what remains open and what has to be resolved next.

When selecting advisers, it is usually more useful to assess their transfer experience than their general reputation alone. A technically excellent adviser may still be a poor fit if they cannot work calmly in a cross-disciplinary process.

Useful questions include:

• Have you already handled transactions close to this one?
• Can you work with other advisers without taking over the whole process?
• Do you produce documents that a buyer, a bank or a notary can actually use?
• Do you understand the family, tax and timing constraints of the file?

A good transfer adviser reduces noise. They do not create more complexity than necessary.

The best time is usually well before the formal discussions begin. Ideally, the preparation phase is used to tidy the numbers, structure the ownership questions, identify sensitive assets and map the family or patrimonial constraints. That leaves more room to negotiate cleanly and less risk of discovering issues when the process is already visible.

If the transfer is already underway, it is still worth bringing the right professionals in. The key is to prioritise:

• what affects the price;
• what affects legal safety;
• what affects family transmission;
• what affects closing.

A strong advisory team does more than reassure the owner. It makes the file readable and defensible. That changes how the buyer sees the company, how the bank sees the financing, and how the family or partners experience the transfer.

In a good file, everyone knows:

• who decides what;
• which documents are authoritative;
• what the next step is;
• which risks are already controlled and which remain open.

That clarity is worth a lot. In practice, it can matter as much as technical expertise.

We can help you coordinate the right advisers and put the file back in the right order before the process starts. The goal is simple: less dispersion, more clarity and a transfer file that is stronger from the outset.

Prepare your transfer with structured support

The right adviser is not just someone technically competent. It is someone who comes in at the right stage, with the right scope, inside a coordinated process. In a business transfer, the quality of the team matters as much as the quality of the company, because it affects the clarity, safety and credibility of the deal.
