Administración desleal in a SAS: signs, duties and what the shareholder can do

Administración desleal (disloyal management) rarely arrives with an announcement. It almost always disguises itself as a business decision: selling an asset to a related company, lending money to a shareholder, contracting with a relative, giving up on collecting a receivable, or pledging company assets as security for someone else's debt. The warning sign appears not because the decision is risky, but because it harms the company and, at the same time, improperly benefits whoever holds control or influence.

This guide is written for the person who lives that problem from the inside: the minority shareholder who suspects something, the manager or legal representative who needs to protect themselves, the board or the shareholders' meeting that has to review matters before escalating, and the family business where trust replaced the rules years ago. The aim is practical: to tell a bad business decision —which does not create liability on its own— from an abuse that causes economic harm, to understand what duties fall on whoever manages a SAS (sociedad por acciones simplificada, Colombia's simplified stock corporation), and to organize the evidence before taking any step that cannot be undone.

This is not a minor matter of wording. In a sociedad por acciones simplificada, whoever manages the company is liable for the harm they cause when they fail in their duties, and the law offers concrete routes against fraud and abuse —including intervention by the Superintendencia de Sociedades (the corporate supervisor, which in Colombia also sits as a court)—. Knowing those tools, and the limits of each one, completely changes how you react.

The concept, without the jargon

What administración desleal is in a company

Administración desleal describes the abuse of position by whoever manages a company, when that person disposes of company assets or takes on obligations for the company in order to favor themselves or a third party, causing economic harm that can be measured. The central idea is at once simple and demanding: the problem is not having made a mistake, but having used the position against the very interest one had a duty to protect.

It is worth setting out the elements that separate abuse from a simple bad outcome, because almost the entire analysis turns on them:

In practice, administración desleal is assessed with documents, dates and specific decisions, not with the feeling that "something smells wrong." A claim this serious should not rest on isolated remarks, but on supporting records that reconstruct what was decided, who decided it, on what information, and who benefited.

The boundary that defines everything

What it is and what it is not: the boundary with the bad business decision

The hardest part of this subject is the boundary. Running a company means taking risks, and many deals go wrong without anyone having acted disloyally. The law recognizes this: an informed decision, taken in good faith and in the interest of the company, does not create liability merely because the outcome was bad. What is reproached is not losing, but betraying the interest one was bound to look after.

That is why the two planes must be kept carefully apart. A significant loss, a disagreement between shareholders or a bet that failed are not, on their own, administración desleal. The difference appears when there is a verifiable transaction, obligation or disposition of assets, carried out with abuse of the position and with a benefit for someone at the company's expense.

The boundary between the bad deal and the abuse is almost never settled by intuition; it is settled by reading papers. This guide does not replace advice on the specific documents in your case, but it does help you organize the conversation and arrive at a consultation with better information.

Three views of the same facts

A lawyer's reading for officers, shareholders and the board

The same set of facts looks different depending on where you stand. Understanding the three positions helps you anticipate how each side will defend itself and what evidence will be decisive.

The three views share a single axis: the duties of whoever manages the company, on which almost the whole analysis is built.

The heart of the analysis

The duties of the officer of a SAS

This is the key to the whole subject. In a SAS, the liability of officers is not something invented for the individual case: it is set by statute. Article 27 of Ley 1258 de 2008 provides that the rules on the liability of the officers of a SAS are those contained in Ley 222 de 1995. And that statute requires whoever manages the company to act in good faith, with loyalty and with the diligence of a good businessman, always acting in the interest of the company and having regard to the interests of all the associates, not only those of whoever appointed the officer or those of the majority bloc.

That standard has very concrete practical consequences, and they are precisely the ones breached in cases of administración desleal:

• Loyalty: putting the company's interest ahead of one's own. Whoever manages the company may not compete with it, nor take for themselves opportunities that belonged to it, nor contract with themselves behind closed doors.
• Good faith: acting transparently, without withholding relevant information from those who have to decide or oversee.
• The diligence of a good businessman: getting informed before deciding, weighing the alternatives and leaving a trail showing that the decision was reasoned, not improvised.
• Handling of conflicts of interest: where a transaction benefits the officer or a related party, it must be disclosed and authorization obtained from the competent corporate body, instead of deciding as if nothing were happening.

The consequence of breaching these duties is also set by statute: the officer is jointly and unlimitedly liable for the harm they cause, through willful misconduct or negligence, to the company, to the shareholders or to third parties. That is why, when administración desleal is assessed, the first question is not "did it go wrong?" but "were these duties met?" And that question has a documentary answer: it appears —or does not— in the minutes, the appraisals, the conflict disclosures and the information available at the time of the decision.

To read a suspicious transaction

A matrix for reviewing a transaction that raises doubts

When a transaction that makes you uncomfortable comes up, it is worth reviewing it with method rather than with headlines. This matrix sets out the transactions that generate the most disputes, the level of legal risk they usually carry, the question that really matters and the prudent action to take so as not to lose evidentiary strength.

The logic of the matrix is always the same: the risk does not lie in the transaction existing, but in there being no way to explain why it was done, who authorized it and who benefited. When those three answers are on record in writing, the transaction defends itself.

In business language

Administración desleal in business language

Put without the jargon: administración desleal appears when someone with management functions or with influence over the company abuses that position and causes economic harm that can be measured. A bad investment is not punished on its own; what is examined is the abuse, the improper benefit and the irregular disposition of assets or obligations assumed against the corporate interest.

That explains why two transactions that look identical can end up very differently. Selling a company property is not in itself a problem: it becomes one if it is sold below value to a company belonging to the same officer, with no appraisal and no authorization. Lending money is not a problem either: it becomes one if it is lent to a shareholder with no term, no collateral and nothing coming back to the company. The conduct to be reproached lies not in the type of transaction, but in how it was decided and in whose favor.

That is why sound business analysis is done beforehand, not afterward: when a sensitive decision comes with sufficient information, disclosure of the conflict, an economic valuation and a verifiable business reason, the same fact that, left in the shadows, would be the evidence against you becomes the best defense of the company and of whoever manages it.

From disagreement to abuse

Why it gets confused with a fight between shareholders

Many of these disputes begin as a textbook corporate argument: the distribution of dividends, a loan between the company and a shareholder, contracts with related persons, a capital increase that dilutes someone, the exit of a shareholder or the handling of the cash. On that ground, disagreement is legitimate and is settled by the company's own rules.

The breaking point comes when the decision stops favoring the company and starts favoring an officer, a relative, a shareholder or a parallel company. At that moment the analysis shifts: what looked like a difference of opinion may reveal a diversion from the corporate interest. The same conversation that seemed a fight over strategy may be hiding a transaction that drained value out of the company and into a particular pocket.

That boundary carries an important consequence for anyone who suspects something: the matter should be treated with the seriousness of a possible abuse, but with the caution of someone who has not yet proved it. The balance lies in documenting first and characterizing afterward.

The ones that leave a trail

Transactions that are best documented

There are transactions that, by their nature, must be especially well supported, because they are the ones that most often conceal an improper benefit. The point is not to forbid them —many are legitimate and necessary— but to require that they leave a trail of why they were done.

• Sales of company assets, above all where the buyer is a related party.
• Loans between the company and its shareholders or officers.
• Debt forgiveness and waivers of the collection of receivables.
• Guarantees given by the company for obligations of shareholders or third parties.
• Contracts with relatives, associates or related companies.
• Advance payments to suppliers and assignments of receivables.
• Increases in borrowing with no clear use for the funds.

In all of them, the minutes should show the same things: that there was sufficient information, that the conflict of interest was disclosed where there was one, that there was an economic valuation and that the transaction had a verifiable business reason. Minutes that say only "approved" protect no one; minutes that explain why protect the company and whoever manages it.

Before the first move

The defense begins before the complaint

Before filing a complaint or responding to an accusation, the decisive thing is to reconstruct the decision at issue. That reconstruction answers simple but determinative questions: who proposed it, who approved it, what information existed at the time, what alternatives were considered, what the real impact was, and whether anyone obtained a benefit for themselves or for a third party.

Without that structure, two things go wrong. On the side of the claimant, a complaint built on impressions looks like a fight between shareholders and loses its force as soon as the other side produces an authorization or a supporting record. On the side of the person defending, answering from memory produces contradictions that are hard to explain later.

An orderly reconstruction also serves a strategic purpose: it lets you decide with a cool head which route suits you. Not every case ends in a criminal complaint. Many are better resolved through the corporate route —liability of officers, nullity of a decision, a negotiated exit— or by combining several. That choice is possible only when the facts are clear and the harm has been quantified.

Without losing evidentiary strength

Minority shareholders: acting without weakening the case

The shareholder who suspects administración desleal usually has less information and less power, and so every move counts. The first instinct —making noise, confronting people in public, accusing— is almost always the one that weakens the case most. The strength of the minority lies not in volume, but in traceability.

A prudent path combines several precautions. It is advisable to request information precisely, in writing, stating which document is being requested and why, and to keep every reply, including the refusals: an unjustified refusal to hand over information also says something. It is advisable to request the minutes and the supporting records of the transactions at issue, and to build a timeline that connects facts, decisions and documents. And it is advisable to avoid public accusations while there is no proof: what is said in excess today is used against you tomorrow.

The aim is not to make life difficult for the other side, but to reach the moment of decision with three things proved: the harm, the abuse of functions and the diversion from the corporate interest. This is where the Superintendencia's doctrine on the protection of the minority takes on its full meaning: the law does not require the small shareholder to simply accept the situation, but it does require that shareholder to arrive with evidence, not with suspicions.

Reducing personal exposure

Officers: how to reduce personal exposure

For whoever manages a company, the best defense against an accusation of disloyalty is built long before the dispute exists, by visibly meeting the duties the law imposes. It is not a matter of distrusting the shareholders, but of leaving evidence that every sensitive decision was taken properly.

Each of these steps answers, point by point, to the duties of loyalty, good faith and diligence in article 27 of Ley 1258 de 2008 and in Ley 222 de 1995. Meeting them is not bureaucracy: it is the proof that you acted as a good businessman.

The route, step by step

How to review the transaction before filing a complaint or responding

Whether you are the one who suspects or the one being pointed at, the first few days shape the case. This route sets out what to do before taking an irreversible decision, so as not to destroy evidence or rush into a step that is hard to reverse.

This sequence works equally well for attack and for defense: the claimant arrives with a solid case, and the person responding avoids the mistakes that turn a legitimate transaction into a suspicion.

The eight warning signs

Signs of abuse of functions and harm to the company

These are the signs that most often precede a case of administración desleal. None of them proves an abuse on its own —each may have a legitimate explanation— but all of them call for a review of supporting records, authorizations and benefit. When several appear together, prudence advises documenting immediately.

• The sale of company assets to a related company at a price with little support, or with no appraisal.
• Loans to shareholders or officers with no term, no collateral and no clear approval.
• Contracts with relatives, associates or related companies with no comparison against market terms.
• Giving up the collection of significant receivables with no verifiable economic justification.
• An advance payment to a supplier that does not deliver, or delivers less than was contracted for.
• The use of company funds for personal expenses on the idea that "we will settle up later."
• Guarantees given by the company to back obligations of shareholders or of third parties.
• The transfer of clients, receivables or commercial information to a parallel company.

To these eight it is worth adding two signs of method rather than of transaction: borrowing approved with no projected cash flow and no clear use for the funds, and later minutes that try to "tidy up" decisions already carried out. This last one is especially delicate: minutes drawn up after the fact in order to justify it do not strengthen the transaction; they usually reveal that the decision was taken without authorization.

Deciding with prudence

A decision table for facing a suspicion

For each typical situation there is a prudent decision that protects your position and an impulsive reaction that weakens it. This table sums up the most frequent ones.

Almost every prudent decision comes down to the same thing: document before you characterize. In these cases impatience is the main enemy of your own case.

Careful with what you put in writing

A protocol for minutes, emails and conflict disclosures

A large part of the damage in these disputes is caused not by the transaction at issue, but by what is written afterward in haste: defensive emails, long voice notes, answers to a bank with no supporting records, or family chats that end up as evidence. Before communicating, it is worth defining the channel, the spokesperson, the documents allowed and the purpose of each reply.

The underlying rule is simple: communicating well is not hiding, but saying what is true, with supporting records and through the right channel. Prudent silence almost never hurts; the hasty word almost always does.

Check off what you have already resolved

Checklist: bad decision or possible abuse?

Use this list to separate a bad business decision from a possible abuse of functions with verifiable harm. Check off each point as you resolve it; whatever is left unchecked is precisely what should be settled before taking the next step.

• The specific decision for this week: what do I have to decide right now about this situation, and what can wait?
• The original document: which document proves the most important account of the facts?
• Formal authority and real control: who held the formal power and who held effective control of the decision?
• Evidence out of context: which payments, signatures, messages or minutes could be read against me out of context?
• Risk of losing evidence: could anyone destroy or alter evidence if I do not act in time?
• The nature of the problem: which part is legal, commercial, family-related, reputational or accounting?
• An acceptable outcome: ¿qué salida sería razonable: negociar, defender, denunciar, corregir o salir?
• Lo que debo dejar de hacer: ¿qué conducta debo suspender desde hoy para no empeorar mi posición?

Gauging the urgency

Semáforo de riesgo: cómo medir la urgencia

No todos los casos exigen la misma reacción. Este semáforo ayuda a calibrar la urgencia según las señales presentes y a no sobreactuar ni subestimar el problema.

El semáforo no reemplaza el criterio, pero ayuda a evitar dos errores opuestos: convertir una inquietud manejable en una crisis, o dejar que una crisis avance porque "todavía no es tan grave". La urgencia la marcan los terceros que presionan, no la incomodidad interna.

Lo que sostiene el caso

Documentos y evidencia que sostienen el caso

Un caso de administración desleal se gana o se pierde por la evidencia. Esta es la documentación que conviene reunir y preservar, tanto para reclamar como para defenderse:

• Bylaws shareholders' agreements y reglas internas de autorización.
• Actas de asamblea, junta directiva y comités donde se discutió la operación.
• Contratos, avalúos, estudios de mercado, cotizaciones y soportes técnicos.
• Estados financieros, auxiliares contables, extractos y comprobantes.
• Relación de socios, administradores, vinculados y beneficiarios de la operación.
• Correos y mensajes sobre la propuesta, la aprobación, la ejecución y los reclamos.
• Informes de revisoría fiscal, auditoría, gerencia y contabilidad.
• Prueba del perjuicio: pérdida, sobrecosto, deterioro de un activo, deuda u oportunidad desviada.
• Evidencia del beneficio propio o de un tercero, cuando exista.

Dos de estos elementos suelen ser decisivos y a menudo se descuidan: la prueba del perjuicio —sin daño medible no hay caso— y la relación de vinculados, que conecta una operación aparentemente normal con el beneficio indebido. Reunirlos antes de que se "ordenen" las cuentas marca la diferencia.

Lo que hunde una reclamación

Errores que debilitan una reclamación

Muchos casos sólidos se debilitan no por falta de razón, sino por errores evitables en la forma de actuar. Estos son los más frecuentes y la decisión que los corrige.

Todos estos errores comparten una raíz: la prisa. Casi nunca se pierde un caso por esperar un día para responder con soporte; se pierde por responder en caliente sin tenerlo.

When to consult

Cuándo conviene hablar con un abogado antes del siguiente paso

Si la situación ya toca documentos, bancos, socios, autoridades, herederos, cónyuges, clientes o reputación, una conversación temprana con un abogado puede ahorrar meses de conflicto. La consulta rinde mucho más cuando llega con hechos verificables y no con versiones sueltas.

Hay momentos en los que postergar la asesoría sale caro: cuando se aproxima una asamblea donde se votará una operación dudosa; cuando un socio empieza a pedir información que antes nunca pidió; cuando aparece la primera comunicación de un banco o de una autoridad; o cuando la decisión que se está por tomar es difícil de revertir. En todos esos casos, una revisión previa permite elegir bien la ruta —societaria, civil, penal o negociada— en lugar de quedar atrapado en la que imponga la contraparte.

Conviene recordar que estas rutas no son excluyentes. La responsabilidad de los administradores por incumplir sus deberes, la nulidad de una decisión, una reclamación civil por el perjuicio y, en su caso, la vía penal pueden coexistir y combinarse según convenga. Definir esa combinación es, en buena medida, lo que distingue una reacción improvisada de una estrategia.
