Which professionals should you involve in a business transfer?

A successful business transfer does not rest solely on finding the right buyer or successor. It depends equally on assembling the right advisory team around the business owner, at the right pace and with genuine coordination between advisers. The most frequent risk is not a complete absence of professionals: it is bringing the right professional in too late, when the financial figures, the contractual clauses or the ownership structure are no longer flexible enough to be adjusted cleanly.

Achieving a clean sale is therefore as much a question of people as of timing. Bringing in the right adviser at the right moment avoids last-minute corrections and protects value. This is especially true for tax arrangements that require early planning, such as the Dutreil pact (pacte Dutreil).

Direct answer. Four professionals shape a business transfer: the chartered accountant (expert-comptable) for account reliability, valuation and restatements; the lawyer for contractual security and the warranty deed; the notary for family, patrimonial, property and donation issues; and the valuation or M&A adviser for pricing, process management and identifying buyers. The order of involvement matters as much as the selection itself: the financial and legal foundations must be in place before the commercial process accelerates.

Before engaging a chartered accountant, a lawyer or a notary, the exact scope of the transaction must be clarified. A family transfer, a sale of business assets (fonds de commerce), a share sale, a donation-partage or a management buyout by an employee each raise different questions. The file is not built in the same way depending on whether the central issue is valuation, taxation, future governance, commercial property or support for the incoming buyer.

That is why it is useful to begin with a simple scoping exercise: who are the parties, what is the target timeline, which assets are within scope and which points are already sensitive? The clearer that framing is from the outset, the more productively each professional can contribute — without duplicating each other's work.

1. The chartered accountant (expert-comptable)#

The chartered accountant prepares the financial figures, brings reliability to the reading of profitability and helps produce accounts that are presentable to outside parties. Without this groundwork, the price discussion quickly becomes unstable. Their role also includes identifying what needs to be put in order before a buyer, a bank or an external adviser begins reading the file.

In concrete terms, the chartered accountant can help to:

• restructure the accounts for sale-readiness;
• isolate exceptional items that distort profitability;
• explain the structure of margins and costs;
• build legible forward-looking financial documents;
• anticipate the questions that will arise during due diligence.

In many transactions, their contribution goes well beyond "doing the numbers". Above all, they enable the business to tell a coherent economic story — without overpromising and without leaving unexplained gaps.

2. The lawyer#

The lawyer secures the letter of intent, the share purchase agreement, the asset and liability warranty (garantie d'actif et de passif) and the exit clauses. They are the lead adviser for contractual safety. Their involvement becomes even more critical when the transaction involves multiple steps, conditions precedent, an earn-out, non-compete commitments or areas of liability that need to be precisely defined.

A good lawyer does more than draft. They help to resolve areas of friction before those become blocking points. It is often the lawyer who translates an economic agreement into a legally sound and workable document that holds up all the way to closing.

3. The notary#

The notary becomes essential as soon as the transfer involves patrimonial, family or property considerations, or a donation or succession mechanism. Their role is particularly significant when the business is part of a broader family project — shares being transferred, a professional property being reorganised, business premises changing hands or assets being split between several heirs.

The notary helps to align the civil, patrimonial and family dimensions of the transfer. In a well-managed process, the notary is rarely called upon as a last resort: they tend to be one of the first supports in the overall strategy.

4. The valuation or M&A adviser#

This adviser helps to position the price, structure the presentation to buyers and manage the negotiation process. They are often the professional who invests the most energy in reading the market, highlighting the business's strengths and keeping the commercial timeline on track.

Their contribution is valuable for:

• framing a defensible valuation range;
• preparing the business presentation;
• prioritising which buyers or successors to approach;
• organising information exchanges in an orderly way;
• maintaining deal discipline rather than allowing the process to fragment into scattered conversations.

In practice, the most effective sequence is generally:

1. the chartered accountant to make the figures reliable; 2. legal counsel to frame the transaction; 3. the notary if the transfer touches the family, the estate or commercial property; 4. the valuation or sale adviser for pricing and process.

This order is not rigid, but it reflects a straightforward reality: the transfer becomes substantially smoother when the financial and legal foundations are ready before the commercial process picks up pace. When preparation comes late, advisers spend too much time correcting what already exists rather than advancing the structure of the deal.

Entrusting each block to a separate adviser without coordination is the most costly mistake. A successful transfer is an exercise in orchestration: figures, legal structuring, taxation, patrimonial questions and timeline must all move forward together. If they do not, the individual pieces may be excellent while remaining incompatible with one another.

In practice, friction most commonly appears on three subjects:

• valuation, when the accounting methodology and the legal reading of the deal are not speaking the same language;
• warranty clauses, when seller and buyer have different perceptions of risk;
• timing, when legal drafting, financing and administrative formalities are not progressing in step.

The right team is therefore not simply the one that "knows its subject". It is the one that knows when to speak, to whom and with which deliverables.

When selecting advisers, it is more productive to assess their experience in transfer contexts than their general standing alone. A few straightforward questions help considerably:

• have they already handled transactions close to yours?
• can they work alongside other advisers without dominating the process?
• do they produce deliverables that a buyer, a bank or a notary can actually use?
• do they understand your timeline and your family constraints?

A technically strong professional who is difficult to coordinate can slow the file. Conversely, an adviser who can simplify and structure may save weeks — sometimes months.

The best moment is usually well before formal discussions are opened. Ideally, the preparation phase is used to revisit the numbers, address the ownership structure, identify sensitive assets and map the patrimonial or family questions. This leaves more room to negotiate cleanly and to correct what needs correcting before the transaction becomes visible externally.

If the transfer is already underway, it is not too late — but priorities must then be addressed in order:

• what determines the price;
• what determines legal security;
• what determines family transmission;
• what determines closing.

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

A strong advisory team does not merely provide reassurance. It makes the file legible and defensible. That changes how the buyer perceives the business, how the banks read the financing, and how the family or partners experience the transfer.

In a well-constructed file, everyone knows:

• who decides what;
• which documents carry authority;
• what the next step is;
• which risks have already been addressed and which remain open.

That clarity is often worth as much as technical expertise in its own right.

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

Prepare your transfer with structured support

To understand why timing matters as much as team selection, see also why anticipating your business transfer pays off.

Fees vary according to the size of the business and the complexity of the transaction. As a rough guide — to be confirmed in each engagement letter (lettre de mission):

These amounts may appear significant, but they should be weighed against their effect on the price: a well-prepared file typically negotiates at 10 to 25% above a poorly prepared one, and well-anticipated tax planning (Dutreil pact, retiring-director relief, share contribution followed by reinvestment — apport-cession) can represent a saving far exceeding the advisory fees. The question is not how many advisers to hire, but which ones to mobilise, at the right moment, with a clear lead.

The right adviser is not simply someone who "knows how to do it". They are someone who comes in at the right stage, with the right deliverables, inside a coordinated process. In a business transfer, the quality of the team matters as much as the quality of the business itself — because it determines the clarity, the security and the credibility of the file.
