Summary : You are about to enter into a partnership and wonder about the real usefulness of a shareholders’ agreement? This document, often neglected or underestimated, is nonetheless the invisible cement that holds a multi-person company together. Without it, conflicts arise where clarity could have prevailed. This article explores the major pitfalls of a poorly drafted agreement and shows how a suitable shareholders’ agreement becomes your safest protection.
In short : A shareholders’ agreement is much more than an administrative formality. It’s the document that organizes your entrepreneurial life together before tensions emerge. The costliest mistakes? Vague drafting, lack of essential exit clauses, failure to ensure consistency with the articles of association, and no mechanisms to manage conflicts. Signed without legal advice or copied-and-pasted from a generic template, a shareholders’ agreement becomes a trap rather than protection. đ
đ Why a well-drafted shareholders’ agreement changes everything
Imagine a small team of three founders launching a startup. Everything is smooth: the passion is shared, the goals aligned, laughter abounds. Then, in month twelve, one of the co-founders wants to leave. Suddenly, everything becomes unclear. Who takes his shares? At what price? Can he continue to work for a competitor? No one knows. And there, for lack of a forward-looking document, the relationship cracks within weeks.
A shareholders’ agreement is precisely that written agreement between shareholders that sets the rules before the unexpected strikes. Unlike the articles of association, filed with the registry and visible to everyone, it remains confidential. It is therefore a space where you can truly say things, anticipate critical scenarios, set safeguards without exposing them to the public.
Between 2025 and 2026, cases of corporate deadlock increased precisely because shareholders discovered, too late, that their agreement (if it exists) is riddled with flaws. â ïž Shareholders’ rights remain unclear, exit mechanisms are unenforceable, non-compete clauses are deemed abusive by a court. The result? Years of litigation and legal costs that exceed the company’s value itself.
đš The most common pitfalls of poor drafting
Confusing articles of association with the shareholders’ agreement
Many entrepreneurs believe the shareholders’ agreement is just an extra formality, or worse, that it redundantly duplicates the articles of association. That’s a fundamental mistake. The articles of association establish your company’s legal structure: its legal form (SARL, SAS), the amount of capital, the powers of the manager or president. The shareholders’ agreement, on the other hand, organizes your interpersonal relationships, your private governance agreements, your mutual promises.
When a clause in the shareholders’ agreement contradicts the articles of association, the articles always prevail vis-Ă -vis third parties. But between shareholders, you can sue for breach of the agreement. The problem arises when the agreement is poorly articulated with the articles: you create contradictory obligations that are impossible to fulfill. đ
For example, your SAS bylaws provide for a simple majority to validate new activities. Your shareholders’ agreement, however, requires unanimity. Which one prevails for a third party doing business with your company? The articles of association. But between the three of you shareholders, who committed a fault? Potentially everyone.
Clauses that are too vague or too broad
A shareholders’ agreement photocopied from a generic legal templates site often contains hollow phrases. “The shareholders undertake to maintain a positive atmosphere”, “no shareholder shall compete with the company”. These sentences sound good, but they solve nothing. In a dispute, they are impossible to enforce.
Conversely, some clauses are too restrictive. A non-compete drafted like this: “The shareholder undertakes not to engage in any activity in the digital sector for fifteen years after his departure” will be annulled for abuse of rights. Judges consider that it is disproportionate. You end up without protection where you thought you had one. đŻ
Precise drafting requires thinking about practice: what thresholds, what durations, which geographic or sectoral scopes are truly necessary? A useful clause must be applicable and defensible in court.
The absence of essential exit clauses
This is perhaps the most serious pitfall: an agreement that provides nothing for the day someone leaves. Yet sooner or later, someone leaves. Illness, desire to change project, burnout, opportunity elsewhere. And there, without a buy-back clause, without a defined valuation, without a good leaver or bad leaver mechanism, you’re stuck.
The good leaver / bad leaver clauses distinguish two scenarios: if you leave “normally” (term respected, transition well handled), you benefit from a fair valuation of your shares. If you leave abruptly or in breach of the agreement (non-compete violated, secrets disclosed), your shares are bought back at a reduced price. It’s common sense: it discourages disloyal behavior. đĄ
Another forgotten element: the right of first refusal clause. If a shareholder wants to sell his shares, do the other shareholders have the right to buy them first? Without this clause, someone could end up with an unexpected shareholder overnight. It’s one of the major pitfalls to avoid when drafting.
Forgetting conflict resolution mechanisms
What happens if two shareholders are in total disagreement about a major decision? Who decides? How is the situation unblocked? Many agreements are silent on this point. The result: you’re left blocked, the company cannot decide anything, and the only way out is litigation.
A good approach provides several levels: first direct consultation, then mediation between shareholders, then an arbitration process or a forced exit clause (if you cannot agree, one of you can force the other to buy his shares, or both must sell to a third party). It is the “financial Russian roulette”, but at least it leaves a way out. đȘ
đŒ When a generic template becomes a false friend
Shareholders’ agreement templates in PDF found online are useful: they give you a structure and show which subjects to cover. But they present a real danger if you sign them without adapting. Every company is unique: your sector, your shareholder makeup (founder shareholders vs. investors), your goals (staying small or raising funds), your personal relationships â all of this changes the picture.
A generic template assumes standard situations. If your situation is atypical â say, a non-operational shareholder who mainly brings capital, or a planned future fundraising â the template doesn’t cover it. You end up with an incomplete agreement that doesn’t anticipate your real challenges. â
The solution? Use a template as a starting point for discussion, but adapt each clause to your reality. List your real issues: who decides on major investments? What happens if a shareholder really wants to leave? How do you handle the entry of a new investor? And then have an attorney review it to check internal coherence and legal compliance.
đ Clauses you must never forget
A complete shareholders’ agreement must cover at least four areas. Let’s start with governance and information rights. Each shareholder must know who makes which decisions, by what majority. Who has veto rights over the sale of key assets? Who decides whether to hire a new person? Who approves the annual budgets?
Next, you need to plan for capital protection. How do you prevent a competitor or a stranger from becoming a shareholder without your consent? Approval and right of first refusal clauses exist for that. And then there are the individual commitments: non-compete for operational shareholders, confidentiality, non-solicitation of clients or employees. Finally, exit mechanisms: how shares are valued, how departures are managed, how everyone exits together if someone makes an acquisition offer.
Governance at the heart of the agreement
Decision-making is the crux of any partnership. Some decisions are trivial (ordering office supplies), others are critical (changing the company’s core business, selling major assets, raising funds). A good agreement distinguishes levels of decision and the authorizations required for each.
In a small SAS with three founding shareholders, you may decide by simple majority to hire a salesperson. But changing the main activity or selling 50% of the shares to an external investor warrants unanimity or a supermajority (two-thirds). It’s not written in the law, you decide. That’s the advantage of the agreement: you set your own rules of the game.
A common mistake: making unanimity mandatory for everything. You then create a situation where a single shareholder can block any decision, even urgent and sensible ones. The agreement becomes a trap rather than protection. Better to distinguish routine decisions (majority) and strategic decisions (unanimity or supermajority). đ
Controlling the entry of undesirable shareholders
Imagine: you built your company carefully. Then one day, one of your shareholders sells his 25% stake to his cousin, without telling you, without asking for your opinion. Legally, that may be allowed if you had nothing in place. But it’s a nightmare for the other two of you.
Approval clauses require the agreement of the other shareholders before allowing someone new to join the capital. Right of first refusal clauses give existing shareholders the right to buy the shares first, at the same price a third party would have offered. Together, they protect you: you retain control over who boards the ship. đĄïž
Note: in a SARL, approval is mandatory by law (the manager or the shareholders must approve the entry of a new shareholder). In an SAS, it is not mandatory unless you provide for it in the articles or the shareholders’ agreement. This is therefore a key point to clarify in your SAS agreement.
Managing exits: good leaver vs. bad leaver
Good leaver / bad leaver mechanisms split departures into two categories, with different financial consequences. If you comply with the agreement, give notice, facilitate the transition, you are a “good leaver”: you are paid for your shares at their true value. If you leave by slamming the door, breaching a non-compete clause, or disclosing secrets, you are a “bad leaver”: your shares are bought at a reduced price, or you may face restrictive conditions.
It’s a fair mechanism that rewards loyalty and penalizes disloyalty. It creates the right incentives: everyone is motivated to leave “cleanly”. And if someone really plans to leave as a traitor, the price to pay is deterrent. âïž
The catch: setting the right price, the right timeframes, the right conditions requires real negotiation at the start. It must be fair for the three or four possible scenarios (ordinary departure, resignation, dismissal, illness). A lawyer can help you calibrate it properly.
đą Shareholders’ agreement in SARL: respecting the legal framework
The SARL (SociĂ©tĂ© Ă ResponsabilitĂ© LimitĂ©e) is a more regulated form than the SAS. The law already provides many rules: mandatory approval, three-quarters majority for important decisions, no free transfer of shares. This means your SARL shareholders’ agreement cannot contradict the law, but it can refine it.
Concretely, a useful SARL agreement will detail the powers of the manager (or managers), anticipate disputes between shareholders, provide for non-compete or exclusivity clauses for managers, and organize a clear transition in the event of a manager-founder leaving. It can also provide for thresholds or procedures stricter than the law requires (for example, unanimity for a new activity, whereas the law only requires 75%).
Warning: in a SARL, the manager has a lot of power. If not bound by an agreement, he can take decisions with serious commitments. A well-designed agreement creates a counterbalance: it limits discretionary power, imposes financial transparency, and requires that certain topics be debated at shareholders’ meetings. đ
âš Shareholders’ agreement in SAS: freedom as responsibility
The SAS (SociĂ©tĂ© par Actions SimplifiĂ©e) offers almost complete statutory freedom. It’s a double-edged sword. On one hand, it’s wonderful: you write your own rules. On the other, it’s dizzying: without clear rules, the majority can do whatever it wants, the minority is exposed, and new investors may be wary.
That’s why the SAS shareholders’ agreement often becomes the company’s true “constitution.” You negotiate the agreement, you outline the president’s powers, you set who can block which decision, you organize how new shareholders enter, how old ones leave. The agreement becomes more important than the articles of association. đȘ
This is particularly true if you raise funds. VCs demand a solid shareholders’ agreement that protects their minority: information rights, veto rights on major decisions, a drag-along mechanism (if you sell the company, minority holders are forced to sell too on the same terms), tag-along rights (if you sell your shares, they can sell as well at the same price). A well-structured SAS shareholders’ agreement anticipates these situations and creates a fair balance.
đŻ Avoid costly mistakes: what to do before signing
You have drafted an agreement (alone, with partners, or from a template) and are about to sign. Here is the checklist you must follow before taking the step. First, confront your agreement with your articles of association. Read both documents side by side. Is there a contradiction? Does a clause in the agreement impose something the articles forbid? If so, one of the two documents must be amended. Generally, it’s better to adapt the agreement, because the articles bind third parties.
Secondly, test the agreement against real scenarios. Ask yourselves: “If X leaves tomorrow, what happens according to this agreement?” Read the exit clauses. Do you all agree on the valuation? On the notice period? On the price for good leaver vs. bad leaver? If you discover an ambiguity, clarify it now, before signing. An ambiguous clause is a clause that will be useless when you really need it.
Thirdly, consult a specialized lawyer at least for a review. Yes, it costs a little. But it’s a tiny investment compared to the cost of later litigation. A lawyer will warn you about dangerous clauses, show you how to clarify hollow wording, and ensure your agreement holds up legally. The mistakes to avoid in a shareholders’ agreement are precisely those a professional will detect easily. đ
Finally, sign properly. A shareholders’ agreement can be informal, but it is strongly recommended that it be signed together, ideally with each person signing under each major clause (not just at the end). Keep several copies, one for each shareholder. Give one to your accountant or lawyer to keep in the archive.
đ± Adapt your agreement to the company’s evolution
An agreement is not set in stone. Your company evolves: maybe you raise funds, maybe you enter a strategic partnership, maybe you absorb another team. Your cap table changes: a new investor enters, a founder partially withdraws. Your challenges also change: going from 5 to 50 employees is an organizational mutation that may justify revising certain clauses.
A good agreement therefore provides a revision clause: every two or three years, you meet to review it, see if there are clauses that no longer work, unpredictable situations that have occurred, or points of irritation. And you adapt it collectively. This shows you take your shared framework seriously. It’s an excellent governance practice. đ
For example: an SAS founded by three shareholders provides nothing for the arrival of a fourth. Then, two years later, you raise a Series A and welcome a new shareholder (a venture capital fund). Your original agreement does not cover him. You must amend it: how does this new shareholder obtain veto rights? On which decisions? How can he participate in governance bodies? It’s important to write this down, otherwise you accumulate gray areas.
âïž The consequences of an absent or poorly drafted agreement
Now imagine a company without a shareholders’ agreement, or with an agreement so vague it settles nothing. After a few years, two shareholders disagree on strategic direction. One wants to sell the company, the other doesn’t. Or one wants aggressive hiring, the other wants to stay small and profitable. Lacking a resolution mechanism, you’re stuck. The company cannot move forward. Employees worry, clients ask questions, and after a few months the value collapses.
In this context, the only recourse is often litigation. You go to court to seek dissolution or forced transfer. It’s long (2-3 years), it’s expensive (10,000 to 50,000 euros minimum in fees), and it’s destructive (the publicity of the dispute can harm your reputation). And at the end of the tunnel, you must sell at a discount to avoid appeals that would prolong everything. đž
Even worse: the absence of a good leaver / bad leaver clause. A shareholder leaves in bad faith â he discloses a client list, creates direct competition. You have no non-compete clause, no penalty. He competes with you in good form. You must sue for damages, prove the harm, and wait years. Even if you win, collecting the money is another matter. A good agreement would have deterred this behavior from the start.
Another invisible consequence: the absence of a right of first refusal. A shareholder sells his shares to an investor you don’t know, without consulting you. You end up with a shareholder who doesn’t share your vision, who spends his time opposing you instead of creating. An agreement with a right of first refusal would have given the other shareholders the chance to buy him out on the same terms. You would have retained control.
Discovering this too late means discovering at a general meeting that a clause of the agreement has been systematically violated and is now worthless because no one reacted in time. Contracts have a temporal armor: after years of silence or acceptance, even a blatant violation becomes difficult to sanction. Hence the importance of putting in place clear and enforceable clauses from the start. đš
đ The bookbinder and the contract: a living metaphor
There is something singular in the work of the artisanal bookbinder. You take loose sheets, without order, without link. You assemble them: you sew, fold, glue. And all of a sudden, it’s a book. Solid. Beautiful. Durable. Because every gesture is thought through, every thread in its place, every fold meaningful.
A shareholders’ agreement is a bit the same. You have three, four people, full of ideas and energy, but potentially chaotic. You assemble them through an agreement: you create an order, a logic, invisible but essential ties. Signed and well drafted, the agreement holds all these individuals together. It unites them without suffocating them.
But if the agreement is poorly stitched â if the threads are not tight, if the folds are messy, if the pages overlap â the book falls apart as soon as it’s handled. Similarly, a poorly drafted agreement, with flaws and ambiguities, snaps under the first real stress: a departure, a fundraising, a conflict. đ
What an old master bookbinder used to say, a hundred years ago: “A good book is one that stands the test of time because the details have been cared for.” A good shareholders’ agreement is one that survives crises because time was taken to draft it well, negotiate it well, and adapt it to the situation.
đ€ The true nature of the agreement: an act of voluntary trust
Signatories of the agreement tell themselves, in short, “We go together, and we want it to work so much that we write down our commitments.” This is not excessive mistrust. It’s benevolent realism. You acknowledge that improvisation creates gray areas, and gray areas create misunderstandings. By writing, you give yourselves a chance to clarify, adjust, and avoid disasters.
The agreement that works is the one you never consult, because it has created such a clear framework that questions no longer arise. Everyone knows who decides what, how we behave if someone wants to leave, what activities are allowed or not. The framework is known, acceptable to all, and you can therefore focus on what you really love: growing together. đ
Those who’ve needed it â when a real conflict arose â thank their stars for having had this document at hand. Because instead of asking “Who is right?”, you can say “Here is what we wrote together, let’s apply it.” It is infinitely simpler, infinitely less costly, infinitely less destructive.
đ Resources and next steps
You are now aware of the major pitfalls of a poorly drafted shareholders’ agreement. If you don’t have one yet, now is the time to create it. If you have one, ask yourself: does it respect all the points listed here? Has it covered critical scenarios (departure, fundraising, conflict)? Is it consistent with your articles of association? Readable and enforceable?
You can start by exploring the 10 essential clauses for any shareholders’ agreement. Then use a basic template to structure a first version. And finally, have it reviewed and refined by an expert in essential agreement clauses before signing.
Remember: a well-designed shareholders’ agreement is not insurance against all problems. But it is insurance against misunderstandings, gray areas, and painful surprises. It’s an investment in the stability and serenity of your shared project. And that is worth a few hours of reflection and a few hundred euros in legal advice. đ
