Corporate deadlock: what it is, how to avoid it and how to resolve it

Corporate deadlock is one of the most delicate situations a company can face. It arises when shareholders or directors are unable to make the decisions required for the company to function normally.

In practice, shareholder conflict rarely arises from a single isolated disagreement. More often, it stems from a lack of initial planning: standard articles of association not tailored to the project, the absence of a shareholders’ agreement, or an equal division of capital without tie-break mechanisms. The result is what in Anglo-Saxon practice is known as a shareholder deadlock.

In this article, we analyse what corporate deadlock is, its most common causes in Spain, how to prevent it, and which mechanisms can be used to resolve it once it has arisen.

What is corporate deadlock?

Corporate deadlock occurs when the corporate bodies—mainly the general meeting or the management body—are unable to adopt the resolutions necessary for the normal functioning of the company.

From a legal perspective, deadlock becomes relevant when it prevents the regular functioning of the corporate bodies and may, where applicable, give rise to the ground for dissolution due to paralysis under the Spanish Companies Act.

It is not merely a disagreement between shareholders. Deadlock exists when the lack of agreement prevents the approval of essential decisions such as:

• Annual accounts
• Capital increases or reductions
• Admission of new investors
• Appointment or removal of directors
• Relevant strategic transactions

From a legal standpoint, deadlock may constitute a statutory ground for dissolution where it results in the paralysis of the corporate bodies to such an extent that their functioning becomes impossible.

Types of deadlock: structural, functional and economic

Deadlock may take different forms, each with distinct legal implications:

Each type directly affects the company’s viability.

Common causes of shareholder deadlock

There are certain scenarios that are particularly prone to shareholder deadlock:

50/50 shareholdings

When two shareholders hold exactly the same percentage of capital, any relevant disagreement can lead to a structural deadlock.

• There is no shareholder with the ability to tilt the decision.
• The issue typically arises in sensitive matters such as capital increases, dividend distribution, entry of new investors or strategic changes.
• If there is no casting vote, an odd-numbered board or an agreed exit mechanism, the conflict can quickly become entrenched.
• This is one of the most common structures in companies founded by two partners.

Conflicting shareholders

Deadlock does not always arise from a technical or legal issue. In many cases, it stems from the deterioration of the personal relationship between shareholders.

• Differences in criteria are eventually transferred to the shareholders’ meeting or the management body.
• Lack of trust prevents normal negotiation, even on day-to-day operational matters.
• In these situations, the conflict often affects employees, clients and suppliers.
• Without mediation, arbitration or structured exit mechanisms, the situation can paralyse the company.

Deadlock in shareholders’ meetings or the board of directors

Deadlock also arises when corporate bodies are unable to adopt resolutions due to lack of sufficient majority.

• This can occur both at the shareholders’ meeting and at board level.
• It is common in equal ownership structures or boards with an even number of members.
• The inability to approve resolutions affects key decisions such as annual accounts, appointments, financing or investments.
• If the situation persists, it may lead to a ground for dissolution due to the inability of the corporate bodies to function properly.

Lack of agreement on strategic decisions

Not all disagreements lead to deadlock, but those affecting key matters for the continuity or growth of the company do.

• This often arises in discussions regarding expansion, internationalisation, financing, hiring of senior management or the entry of new shareholders.
• When the bylaws or shareholders’ agreement do not clearly distinguish which matters require qualified majorities, tensions increase.
• The problem worsens when the company needs to react quickly, but the corporate structure prevents decision-making.
• This type of disagreement is often the precursor to an operational or structural deadlock.

Disagreements on financing or dividend distribution

One of the most common sources of conflict is the difference in views regarding financial matters.

• One shareholder may prefer to reinvest profits, while the other prioritises dividend distribution.
• Disagreements may also arise regarding additional contributions, capital increases or debt.
• If the company requires liquidity and no agreement is reached, the deadlock may directly affect its operations and solvency.
• This type of conflict is particularly relevant in SMEs, family businesses and companies with a small number of shareholders.

Lack of a shareholders’ agreement or poorly adapted bylaws

In many cases, the real cause of deadlock is not the disagreement itself, but the absence of clear rules to manage it.

• Standard bylaws rarely address deadlock scenarios or structured exits.
• The absence of a shareholders’ agreement leaves key aspects unregulated, such as pre-emption rights, tie-break mechanisms or deadlock clauses.
• This often leads to conflicts being taken to court, which could have been avoided with proper planning.
• The more closely held and personal the company is, the more important this initial structuring becomes.

Unwanted entry of a third party

The entry of a new shareholder without prior consensus can significantly alter the internal balance of the company.

• This typically occurs when transfer restrictions have not been properly regulated.
• The entry of a third party may generate distrust, disputes and loss of control over strategic decisions.
• In limited liability companies, this risk can be mitigated through pre-emption rights, rights of first refusal, withdrawal rights or prior approval mechanisms.
• It is a very common trigger of corporate conflicts in family businesses and closely held companies.

Consequences of corporate deadlock

Corporate deadlock is not just an internal issue between shareholders. When the lack of agreement persists over time, it directly impacts the company’s operations, reputation, and financial viability.

In many cases, the real damage comes not from the conflict itself, but from the inaction it generates.

Paralysis of strategic decision-making

Prevents approval of capital increases, investments, or growth plans. The company becomes stagnant while the market moves forward, losing competitiveness.

Inability to operate normally

May block approval of accounts, budgets, or financing. In 50/50 structures, even a minor disagreement can lead to formal non-compliance and operational dysfunction.

Loss of financing or investment

Investors avoid companies with internal conflict. Deadlock reduces the company’s valuation and may prevent funding rounds or corporate transactions.

Reputational risk

Tensions between shareholders create uncertainty among employees, clients, and suppliers, affecting the company’s stability and image.

Forced liquidation

If the paralysis becomes permanent, judicial dissolution may be requested. The company enters liquidation, ceases operations, and distributes its assets, bringing the project to an end.

Deadlock risk factors in Spanish companies

Corporate deadlock rarely arises suddenly. In most cases, it results from a combination of structural and relational factors which, if not properly addressed from the outset, ultimately affect the company’s decision-making capacity.

In practice, certain corporate structures significantly increase the risk of conflict. Identifying them allows companies to anticipate issues and implement appropriate preventive mechanisms.

50/50 structures and structural deadlock

This is the most common cause. While there is strategic alignment, it may work smoothly. However, in the event of a significant disagreement—such as capital increases, dividend distribution, entry of new investors or strategic changes—the deadlock becomes structural.

Without a casting vote or an agreed exit mechanism, paralysis is almost inevitable.

Lack of foresight in bylaws or shareholders’ agreements

The use of standard bylaws often fails to regulate what happens in the event of a prolonged deadlock or how a shareholder exit should be structured.

The absence of a solid shareholders’ agreement is one of the main sources of deadlock in companies with multiple shareholders.

Personal or strategic conflicts between shareholders

Differences regarding reinvestment, risk appetite or business direction may escalate to the shareholders’ meeting or the management body, resulting in operational deadlock.

This factor is particularly common in family businesses or smaller companies.

Inactivity of the management body

This may occur when joint directors fail to act in coordination or when the board of directors cannot reach the required majority.

Prolonged inactivity can paralyse the company’s management and may give rise to liability if necessary decisions to protect the company’s interests are not taken.

How to prevent corporate deadlock

Corporate deadlock is rarely unpredictable. In most cases, it can be avoided through proper legal planning from the moment the company is incorporated or in the early stages of its development.

Prevention does not mean mistrusting your partner but recognising that disagreements can arise in any business project. A well-designed structure allows them to be managed without paralysing the company.

Tailored (non-standard) bylaws

One of the most common mistakes is using generic bylaws without adapting them to the specific reality of the project.

Bylaws should be designed based on:

• The number of shareholders
• The shareholding structure
• The presence of investors
• The chosen management system
• The desired level of control

A company with two 50/50 shareholders cannot be structured in the same way as one with a clear majority shareholder. Lack of customisation is one of the main causes of future deadlocks.

The shareholders’ agreement as a key preventive tool

A shareholders’ agreement allows regulation of aspects that are not always suitable for inclusion in the bylaws and require greater flexibility.

It is particularly relevant when:

• There is an equal distribution of capital
• Shareholders have different profiles (industrial vs financial)
• The entry of new investors is expected
• A structured exit mechanism is needed

A well-drafted shareholders’ agreement should include conflict resolution mechanisms, valuation systems and deadlock clauses.

Control clauses and balance of power

Preventing deadlock requires properly designing the decision-making system. Common tools include:

The goal is not to make decision-making more difficult, but to balance power without creating automatic deadlocks.

A well-designed corporate structure combines tailored bylaws, a solid shareholders’ agreement and clear tie-break mechanisms. This combination significantly reduces the risk of corporate deadlock.

Restrictions on the transfer of shares in a Spanish limited liability company (SL)

One of the most effective ways to prevent corporate deadlock is to control the composition of the share capital and the entry of new shareholders. The unwanted entry of a third party is one of the most common sources of tension between shareholders. In closely held companies, particularly limited liability companies, the identity of the shareholders forms part of the internal balance of the business.

For this reason, controlling the transfer of shares in an SL is not merely a formal issue, but a key element in preventing conflicts that may lead to corporate deadlock.

Spanish law allows for the introduction of restrictions, but within certain limits.

When can a company restrict the transfer of shares?

In limited liability companies, the law is based on a clear principle: shares are not freely transferable, unlike in public limited companies.

This means that the bylaws may establish restrictions on transfers, provided they do not amount to an absolute or indefinite prohibition.

It is common to require:

• Prior approval from the shareholders’ meeting
• Formal notification of the intention to transfer
• Compliance with pre-emption rights

These restrictions aim to preserve the closed nature of the company and prevent the entry of unwanted third parties.

Difference between prohibiting and restricting share transfers

Transfer restrictions must comply with the limits set by the Spanish Corporate Enterprises Act. In particular, they cannot be structured in a way that indefinitely deprives a shareholder of a reasonable exit.

Reasonable limitations—such as pre-emption rights or prior approval requirements are valid, provided they ultimately allow the transfer under certain conditions.

Mediation and commercial arbitration

Mediation and arbitration are out-of-court mechanisms that allow disputes to be resolved without resorting directly to ordinary courts.

Mediation facilitates negotiation between shareholders through the intervention of a neutral third party who helps them reach an agreement.

Commercial arbitration, if provided for in the bylaws or shareholders’ agreement, allows an arbitrator to issue a binding decision more quickly and confidentially than court proceedings.

Both options help reduce the reputational and financial impact of the conflict.

Appointment of an independent director

In situations of deadlock within the management body, appointing an independent director or neutral third party can be an effective solution.

Their role is to:

• Unlock technical decisions
• Execute pending resolutions
• Act impartially in the best interest of the company

In some cases, corporate, registry or judicial solutions may also be explored to restore the proper functioning of the management body, depending on the specific circumstances.

Casting vote

If provided for in the bylaws, the chairman may have a casting vote in the event of a tie.

This is particularly useful in 50/50 structures or balanced boards. While it does not resolve structural conflicts, it helps avoid temporary deadlocks.

Separation or exit of shareholders for just case

When coexistence between shareholders becomes unworkable, the right of separation or, in certain cases, the exclusion of a shareholder, may be triggered.

Spanish law provides for legal grounds for separation, such as substantial changes to the corporate purpose or the lack of dividend distribution under certain conditions.

Additionally:

• Bylaws may include further grounds with corporate effect
• Shareholders’ agreements may regulate exit mechanisms (mainly with contractual effect between the parties)

In such cases, deadlock is resolved through the orderly exit of one shareholder, including valuation and settlement of their stake.

Advanced deadlock resolution clauses in shareholders’ agreements (Deadlock Clauses)

In companies with equal shareholding structures or financial investors, it is common to include deadlock clauses in shareholders’ agreements to resolve structural conflicts.

These clauses establish a predefined exit mechanism when decision-making is blocked, allowing one shareholder to exit in an orderly manner without resorting to judicial dissolution.

Common deadlock clauses in shareholders’ agreements

These clauses share a common feature: they force one shareholder to exit when the conflict becomes irreversible, but under previously agreed rules.

A critical element in all cases is the proper regulation of valuation methods and execution timelines. Poorly drafted clauses may generate more disputes than solutions.

These clauses are not specifically regulated under Spanish law and require careful drafting to ensure their validity and enforceability.

Other relevant clauses related to deadlock

In addition to strict deadlock clauses, shareholders’ agreements often include complementary mechanisms:

These tools do not always resolve a deadlock on their own, but they reduce structural conflict risk and facilitate orderly exits.
