Exclusion of a shareholder from a SAS: 6 key points before suing
Expelling a shareholder from an SAS: review the bylaws, the grounds, the evidence, the valuation, the buy-out and the risks before you vote or sue.

Excluding a shareholder from a SAS (sociedad por acciones simplificada, Colombia's simplified stock corporation) can be a powerful tool, but a dangerous one if it is used badly. It is not enough that the shareholder turns out to be inconvenient, difficult or unwelcome: the first question is not whether it is advisable to exclude them, but whether the bylaws provide an applicable ground and a defensible procedure. The answer to that question decides whether a desired exit ends in a clean decision or in a longer and more expensive dispute.
This guide is written for shareholders, boards, legal representatives and investors in a SAS who are weighing a forced exit, a buyback or a shareholder dispute. The idea is to give you a route for deciding with documents, dates and evidence —and not in the heat of the moment—, so that the decision does not end in a challenge, a claim for damages or the decapitalization of the company.
In briefIn a SAS, excluding a shareholder is viable only if the bylaws provide for the ground: the Article 39 of the Law 1258 of 2008 requires that the exclusion be agreed in the bylaws, that the shareholders' meeting approve it by half plus one of the shares present, without counting the vote of the shareholder targeted by the measure, that due process be observed and that the capital contributions be reimbursed. Without a clause in the bylaws there is no exclusion. This mechanism should not be confused with the piercing of the corporate veil (art. 42) or with the abuse of the right to vote (art. 43): these are three different routes, with different requirements and different authorities.
The direct answer
Can a shareholder be excluded from a SAS in Colombia?
Excluding a shareholder from a SAS is viable only if the bylaws provide grounds for exclusion and the applicable procedure is followed, including reimbursement where appropriate. It is not enough that the shareholder is inconvenient, breaches obligations informally or that trust has been lost: the decision must have a basis in the bylaws, sufficient evidence and corporate due process.
In practice, exclusion has to be assessed with documents, dates and specific decisions, not with isolated accounts or stray remarks. Before calling a shareholders' meeting it is worth going through four filters in order, because skipping any of them is exactly what opens the door to a challenge.
Bylaws before emotions
Exclusion is born of the document, not of anger
The most frequent mistake is to treat exclusion as an improvised punishment for a shareholder you dislike. The SAS works the other way around: the power to exclude is not presumed, it is agreed. If the clause was not written down while there was still good faith, creating it in the middle of the fight is far harder, because each shareholder will defend the reading that suits them best.
This guide does not replace advice on the specific documents in your case, but it does help you organize the conversation, avoid silent mistakes and arrive at a consultation better informed. The goal is not to win an emotional argument, but to take an early, documented decision that changes the course of the conflict before it becomes ungovernable.
Depending on where you stand
A lawyer's reading for shareholders, the legal representative and investors
The same conflict looks different depending on the position you hold in the company. It is worth reading the situation from your own role before making a move:
Before voting
A matrix for deciding whether exclusion applies
Not every conflict is resolved by excluding. This matrix cross-references the situation with the prudent route and the risk worth watching in each scenario, so that you do not force a route the case cannot bear:
| Situation | Does exclusion apply? | Prudent route | Risk to watch |
|---|---|---|---|
| Bylaws with no ground | In principle, not by that route | Consider negotiation, a unanimous amendment or breach-of-contract actions | Excluding with no basis in the bylaws |
| A clear ground and solid evidence | It may be viable | Shareholders' meeting, due process and reimbursement | The vote of the shareholder concerned counted incorrectly |
| Change of control in a corporate shareholder | It may apply if provided for | Apply the bylaws and corporate rules | Failing to check the duty to inform |
| Harmful conduct with no clause | Not automatically | Liability, abuse, precautionary measures or a negotiated exit | Confusing a penalty with exclusion |
The underlying idea
Excluding a shareholder is not an improvised penalty
Excluding a shareholder from a SAS requires reviewing, in this order, the bylaws, the ground, the procedure, the vote, corporate due process, valuation and reimbursement. Each of those steps is a point at which the decision can fall apart if it was handled carelessly. Using exclusion as emotional punishment does not speed up the departure of the inconvenient shareholder: it makes it more expensive, because it turns a corporate formality into a dispute on the legal, commercial and reputational fronts all at once.
The first review
The bylaws, before anything else
In a SAS the bylaws may provide grounds for exclusion, but that clause has to exist before the conflict. If it does not, adding or amending it is a particularly demanding amendment to the bylaws: touching a rule that goes to the root of a shareholder's continued membership usually requires the backing of all the subscribed shares, something that is almost impossible to obtain when the problem shareholder is precisely the one who would vote against.
That is why many companies discover too late that they cannot create a ground tailored to the inconvenient shareholder once the conflict has already broken out. An exclusion clause is like an exit clause: it only works if it was drafted calmly, not in the middle of the fight. That is why it is worth reviewing in cold blood which clauses in the bylaws of a SAS prevent disputes.
What makes a ground strong
Grounds: serious conduct, strong evidence and proportionality
Having an exclusion clause is not enough; the ground invoked must be serious, proven and proportionate to the penalty. A useful ground connects with verifiable breaches, not with perceptions. These are the situations that, well documented, usually sustain a decision:
- Failure to pay in the capital contributions the shareholder committed to.
- Breach of the restrictions on the transfer of shares agreed in the bylaws.
- Competing with the business or diverting its activity into a business of one's own.
- Improper use of the company's commercial or strategic information.
- A conflict of interest not disclosed when contracting with the company.
- Breach of shareholders' agreements or of acts that directly affect the company.
The evidence must show three things at once: the conduct, its impact and its connection with the ground. Mere friction among shareholders, without that thread, will not withstand legal argument.
When there is no clause
If there is no ground in the bylaws, exclusion must not be improvised
In a SAS, exclusion always starts from the bylaws. The Article 39 of Ley 1258 de 2008 allows grounds for exclusion to be provided for, requires the shareholders' meeting to approve it by half plus one of the shares present and requires the corresponding reimbursement to be dealt with. Creating or amending a clause as sensitive as this one, by contrast, is an amendment that normally requires the backing of all the subscribed shares. That is why, before calling the meeting, you have to confirm whether the ground already exists, whether it covers the specific conduct and whether the procedure respects defense, evidence, majority and valuation.
The absence of a ground does not mean standing still. Depending on the conflict and the evidence available, other routes can be considered: negotiating a purchase of shares, retirement agreements, an amendment to the bylaws by unanimity, breach-of-contract actions, liability of officers, a challenge to resolutions or measures before the Superintendencia de Sociedades (the corporate supervisor, which in Colombia also sits as a court). The key is to choose the route the case can actually support.
Exclusion, piercing of the veil and abuse of the vote: three routes that must not be confused
The exclusion of the Article 39 is an internal decision of the company to remove a shareholder where the bylaws provide for it. It is different from the piercing of the corporate veil of the Article 42 —the piercing of the corporate veil, which, in the face of fraud or harm to third parties, makes the shareholders and officers who carried out, took part in or facilitated the fraudulent acts jointly and severally liable, and which is declared by the Superintendencia de Sociedades— and also from the abuse of the right to vote of the article 43 —of majority, of minority or of parity—, which can lead to the resolution being declared null and to damages for the harm caused, likewise before the Superintendencia. In practice: if what you have is a shareholder committing fraud or a majority voting in order to buy cheap, the route may not be exclusion, but article 42 or article 43.
Read Ley 1258 de 2008 (arts. 39, 42 and 43) →Distinguishing those three routes matters because it marks the border between a legitimate exclusion and an abuse of the majority. An exclusion is legitimate when it rests on a ground agreed in the bylaws, on serious evidence and on real due process; it stops being legitimate when the removal of the shareholder is used as a pretext to expropriate their stake or to keep them from the economic benefits that belong to them. That difference —easy to state, hard to sustain in the middle of a conflict— is what the authority examines when someone challenges the decision.
What the Superintendencia has said about protecting the minority shareholder
In Sentencia n.° 800-52 of June 9, 2016, the Delegatura de Procedimientos Mercantiles (the Commercial Proceedings Division) of the Superintendencia de Sociedades —in a dispute among the shareholders of a family company— recalled that those who manage and those who control the company owe duties to the other shareholders (in line with article 23 of Ley 222 de 1995) and that corporate law protects the minority shareholder against oppression or the expropriation of their economic rights. Applied to exclusion, this sets a clear limit: the majority may not use a resolution of the shareholders' meeting to keep the minority from what belongs to them. Where the removal lacks a ground in the bylaws, evidence or due process, it stops being an exclusion and comes close to abusive conduct, with the consequences of article 43.
This judgment was handed down by the Superintendencia in the exercise of judicial functions: it binds the parties to that proceeding and is cited here as persuasive guidance.
Read Sentencia 800-52 de 2016 (Superintendencia de Sociedades) →The procedure
Shareholders' meeting, vote and corporate due process
Even where the ground exists, the form matters as much as the substance. The exclusion must be conducted formally: proper notice of meeting, a clear agenda, access to information, a real opportunity for the shareholder to give their side, robust minutes and voting in accordance with the bylaws and the law. The Article 39 requires approval by the shareholders' meeting with half plus one of the shares present; taking care how that vote is counted —especially the vote of the shareholder concerned— is decisive if the decision is not to be open to challenge.
The minutes must not merely declare the exclusion: they must give reasons for it. They have to record the ground, the facts that make it out, the evidence reviewed and the fact that an opportunity to defend was given. Poor minutes, drafted in haste, are one of the cracks through which nullity later enters.
Where it is won or lost
Valuation and reimbursement: the other half of the conflict
The conflict does not end when the shareholders' meeting decides to exclude. That is where the second half begins: the valuation of the stake, the reimbursement of the capital contributions ordered by the Article 39 and, where appropriate, the reduction of capital. This stage requires financial statements, a review of liabilities, cash, contingencies and a defensible valuation method that can hold up if the departing shareholder disputes it.
This is where many well-founded exclusions become expensive: a valuation made with incomplete figures, or a reimbursement that decapitalizes the company and affects its creditors, can turn a clean exit into a new lawsuit. It is worth treating the reimbursement with the same care with which the decision to exclude was handled.
What can go wrong
Risks if the exclusion is badly built
A weak exclusion rarely stays quiet. It usually comes back as a challenge, nullity of the resolution, a claim for damages, reputational blockage or a negotiation far more expensive than the one you were trying to avoid. And the damage is not limited to the relationship among shareholders: it can also hit banks, clients, personal guarantees and the day-to-day running of the business, just when stability is most needed.
Before making a move
A practical route before voting
Before calling the shareholders' meeting, it is worth preparing the ground: building the matrix of ground and evidence, estimating the economic impact, having a negotiated alternative ready and projecting the cash plan for the reimbursement. If there is room, it is worth exploring an agreed exit before forcing the exclusion, because it is almost always faster and cheaper. To prepare it, it helps to understand how to negotiate and prove a corporate dispute between shareholders. A negotiated exit usually rests on these pieces:
- An independent valuation that both sides accept as a starting point.
- Confidentiality about the terms and the reasons for the exit.
- A non-compete covenant that is reasonable in time and scope.
- An orderly handover of the company's information, passwords and assets.
- Release of the departing shareholder's personal guarantees, co-debts and sureties.
The first five steps
What to do before voting or suing
When the conflict heats up, the temptation is to act fast. What we see in practice is that the first moves decide the outcome. Before voting an exclusion or filing a lawsuit, it is worth putting your own house in order:
Red flags
Signs that the exclusion may be open to challenge
There are patterns that repeat in the exclusions that later fall apart. Several of them share one root: using the removal of the shareholder for something other than what the ground allows. If you recognize any of these in your case, it is worth stopping and reviewing before calling the meeting, because this is exactly where an exclusion stops looking legitimate and starts to look like an abuse of the majority:
- The company wants to exclude, but the bylaws never included a ground.
- The ground is broad, of the "bad behavior" kind, and does not withstand serious legal argument.
- The shareholder competes with the company using internal commercial information.
- The shareholder does not pay in the capital contributions and, even so, blocks cash decisions.
- The majority uses the exclusion to buy a valuable stake cheaply.
- A minority shareholder threatens clients in order to force a buyback.
- The shareholders' meeting is called in haste and the minutes are poor, leaving the door open to a challenge.
- The valuation is made with incomplete figures or out-of-date financial statements.
- The reimbursement decapitalizes the company and affects the creditors.
- The exit negotiation forgets personal guarantees, co-debtors or promissory notes.
Risk and decision
Decision table in the exclusion of a shareholder
Before escalating, it is worth reviewing point by point where the real risk lies and what the prudent decision is on each front:
| Situation | Real risk | Prudent decision |
|---|---|---|
| Is there a ground in the bylaws? | If there is none, the exclusion is risky | Consider an amendment to the bylaws, a negotiated exit or an alternative route |
| Is the evidence documentary? | Stray witness statements may not be enough | Organize the document file before calling the meeting |
| Is there harm to the company? | It may look like a personal conflict | Quantify the economic and operational impact |
| Is the valuation defensible? | The exit becomes more expensive or falls apart | Obtain an independent financial opinion |
| Is there a reduction of capital? | Risk to creditors and to liquidity | Review the applicable rules and the cash plan |
| Is there an arbitration clause? | A mistake as to forum or as to timing | Choose the route before escalating |
How and through which channel to communicate
A protocol for the notice of meeting, the minutes and formal communications
A large part of the damage in an exclusion is not born at the shareholders' meeting, but in messages sent in haste: defensive emails, long voice notes, replies to banks with nothing to back them up, or family chats that end up as evidence. Before communicating, it is worth deciding on the channel, the spokesperson, the documents that may be shared and the purpose of each reply:
| Channel | Risk if it is used badly | Practical rule |
|---|---|---|
| WhatsApp or internal chats | Impulsive remarks, partial screenshots and loss of context | Write briefly, keep the full thread and avoid threats |
| Corporate email | Unintended admissions or incomplete attachments | Answer with verified facts and reviewed attachments |
| A meeting with shareholders or family | Conflicting accounts and promises that are hard to prove | Prepare an agenda, a note of the meeting and commitments in writing |
| An answer to a bank or an authority | Contradictions or handing over too much information | Prepare a document file and a legal position |
| A communication to employees or clients | Reputational noise and information leaks | Appoint a spokesperson and limit the message to operational continuity |
The preliminary review
Questions that decide whether the exclusion is viable
If you come to the meeting with your lawyer already holding these answers, the analysis usually moves faster and with less noise. It is not about having everything resolved, but about separating verifiable facts from hypotheses and from pending decisions:
- What specific decision do I have to make this week about the exclusion?
- Which original document proves the most important account?
- Who held the formal authority and who held actual control?
- Which payments, signatures, messages or minutes could be seen out of context?
- Who could destroy or alter evidence if action is not taken in time?
- Which part of the problem is legal, commercial, family-related, reputational or accounting?
- What practical outcome would be acceptable: to negotiate, to defend, to file a complaint, to correct or to exit?
- What must I stop doing as of today so as not to worsen my position?
Gauge the temperature
Risk traffic light in the exclusion of a shareholder
Not every conflict calls for the same reaction. This traffic light helps you gauge the response according to how far the problem has advanced:
| Level | How it looks | Suggested response |
|---|---|---|
| Low | There is unease, but the documents are complete and no one is pressing from outside | Put the file in order and request a preventive review |
| Medium | There are payments, signatures, messages or documents that are incomplete | Pause sensitive moves and prepare the timeline |
| High | A bank, a shareholder, an authority, an auditor or an opposing party is asking for an answer | Respond only with a strategy and reviewed supporting records |
| Critical | There is a criminal complaint, a precautionary measure, an account freeze, a public threat or a loss of control | Activate the defense, preserve the evidence and decide who speaks for the company |
Build the document file
Documents and evidence worth having ready
An exclusion stands on papers, not on impressions. Before calling the meeting, it is worth gathering and reviewing this document file:
- The bylaws in force, with their grounds and procedures.
- Earlier minutes recording warnings or breaches.
- Evidence of unpaid capital contributions or of unfulfilled commitments.
- Emails, contracts and chats concerning the conduct complained of.
- Evidence of competing activity, diversion of clients or improper use of information.
- Up-to-date financial statements and accounting records.
- A certification of liabilities, contingencies and available cash.
- A valuation proposal or an independent report.
- The notice of meeting, the agenda, the proxies and the attendance records.
- A draft of the minutes giving clear reasons, with its annexes.
What makes the case more expensive
Mistakes that can void the exclusion or make it more expensive
Some mistakes are not noticed on the first day, but they come back once money or disagreements are involved. These are the ones that cost the most and the decision worth taking instead:
| Mistake | Why it makes the case worse | Better decision |
|---|---|---|
| Answering from memory | It creates contradictions and leaves loose ends | Prepare a timeline and a document file |
| Deleting chats or files | It can look like concealment and it destroys context | Keep the originals and complete copies |
| Making accusations without proof | It closes off negotiations and weakens your credibility | Put the facts in order before giving them a legal label |
| Signing to buy time | It shifts liability onto whoever signs | Record your reservations and require competent supporting advice |
| Mixing family, business and reputation | It raises the temperature and makes agreement harder | Separate the conversations and the decision-making channels |
When to consult
When it is worth talking to a lawyer before the next move
If the exclusion already touches documents, banks, shareholders, authorities, heirs, spouses, clients or reputation, an early conversation can save months of conflict. A consultation yields more when it arrives with verifiable facts and not with loose accounts: with the bylaws in front of you, the timeline built and the pending decision clearly defined, the lawyer can go straight to strategy instead of spending the meeting reconstructing what happened.

Before voting an exclusion
Checklist: tick off what you have already resolved
Use this list as a quick check before calling the shareholders' meeting or suing. Tick off each point as you resolve it with your lawyer; whatever is left unticked is exactly what needs to be settled before making a move:
- A ground in the bylaws: do the bylaws provide for exclusion, and does the specific conduct fit that ground?
- Documentary evidence: does the file show the conduct, its impact and its connection with the ground, beyond stray witness statements?
- A valid majority: can the shareholders' meeting approve it by half plus one of the shares present, counting the vote of the shareholder concerned correctly?
- Due process: is there a proper notice of meeting, an opportunity to defend, and minutes that give reasons rather than merely declaring?
- Reimbursement and cash: is the valuation defensible, and does the reimbursement avoid decapitalizing the company or affecting the creditors?
- An alternative route: have you assessed a negotiated exit in case the exclusion turns out to be more expensive or more fragile than an agreement?
