Shareholders' Agreement vs Partners' Agreement 2026

The choice of a legal structure for carrying on an economic activity often raises the question of how to organise relations between partners or shareholders. Beyond the articles of association, which form the legal foundation of the company, managers and investors frequently turn to supplementary agreements to specify their reciprocal rights and obligations. This naturally leads to questions about how a shareholders' agreement (pacte d'actionnaires) differs from a partners' agreement (pacte d'associés), two legal instruments with similar purposes but different terms of application.

Legal nature and scope of the agreements

The shareholders' agreement in companies limited by shares

The shareholders' agreement is a private-law contract entered into between all or some of the shareholders of a public limited company (SA) or a simplified joint-stock company (SAS). This contractual agreement supplements the articles of association by organising the particular relations between the signatories to the agreement.

The legal validity of the shareholders' agreement rests on the general principles of contract law. The parties retain their freedom of contract, subject to compliance with public policy and with the mandatory provisions of the French Commercial Code on the functioning of companies limited by shares.

The partners' agreement in other corporate forms

The partners' agreement applies to companies in which the participants hold partnership interests (parts sociales) rather than shares. This category mainly covers limited liability companies (SARL), general partnerships (SNC), civil property companies (SCI) and limited partnerships (sociétés en commandite simple).

The drawing up of a partners' agreement follows the same contractual principles as the shareholders' agreement, but must take account of the specific operating features of each corporate form concerned. The differences in regime between the two instruments, and their tax and estate planning aspects, are compared in our article on the shareholders' agreement and the partners' agreement.

Objectives and typical content of the agreements

Governance and control clauses

Shareholders' agreements and partners' agreements pursue convergent objectives as regards the organisation of power within the company. These agreements make it possible in particular to provide for mechanisms for appointing managers, allocating seats on management bodies and taking collective decisions on strategic direction.

Governance clauses may also provide for periodic information to the signatories to the agreement, in addition to the statutory reporting obligations. This aspect is particularly relevant in companies bringing together financial investors and operational managers.

Transfer and succession mechanisms

Regulating movements of securities is a central issue in shareholders' agreements and partners' agreements. These contractual instruments make it possible to organise the conditions for transferring company securities, beyond the provisions of the articles of association.

Pre-emption, first offer or reinforced approval clauses are thus frequently found in these agreements. They aim to maintain the stability of the shareholder or partner base while preserving the interests of the stakeholders.

Liquidity mechanisms, such as "tag along" or "drag along" clauses, allow minority holders to benefit from the sale terms negotiated by the majority and allow the majority to oblige minority holders to take part in a sale of the whole company, respectively.

Legal regime and enforceability

Binding force between the parties

The shareholders' agreement and the partners' agreement both produce their legal effects in the relations between the signatories, in accordance with the general principles of contract law. Article 1103 of the French Civil Code provides that "contracts lawfully formed take the place of law for those who have made them".

This binding force allows the parties to rely before the courts on the undertakings given under the agreement. In the event of breach of the contractual stipulations, the usual mechanisms of contractual liability apply.

Limits on enforceability against third parties

The legal reach of the agreements is nevertheless limited by their nature as private instruments (actes sous seing privé), which are in principle not enforceable against third parties. This limitation is particularly important for clauses relating to the exercise of voting rights or the transfer of company securities.

The courts do, however, accept certain exceptions to this principle, in particular where the third-party acquirer knew of the existence of the agreement and its stipulations at the time of the transaction in dispute. This knowledge may result from explicit information or from the circumstances of the acquisition.

Relationship with the articles of association

The provisions of the shareholders' agreement or partners' agreement cannot derogate from the mandatory rules of company law. In the event of conflict between the stipulations of the agreement and the provisions of the articles of association or of statute, the latter prevail.

This hierarchy of norms calls for particular care when drafting the agreements, in order to avoid inserting clauses liable to be held void. Consulting a legal adviser experienced in this area is essential to secure the validity of these instruments.

Procedural and practical features

Conclusion and amendment

The conclusion of a shareholders' agreement or partners' agreement requires the free and informed consent of all the signatory parties. The rules on the formation of contracts apply in full, including the requirements of capacity, subject matter and cause.

Subsequent amendment of the agreement generally requires the unanimous agreement of the signatories, unless otherwise stipulated by provision for revision by qualified majority. This requirement of unanimity can be a constraint in practice, particularly in agreements involving many participants.

Duration and termination of the agreements

Agreements may be entered into for a fixed or an indefinite term. In the latter case, each party retains the right to terminate the agreement unilaterally, subject to reasonable notice.

The agreement may also terminate upon the occurrence of expressly provided conditions subsequent, such as the company's stock market flotation, its sale as a whole or its dissolution.

Legal security issues

Drafting and negotiation of clauses

The quality of drafting of the shareholders' agreement or partners' agreement largely determines its practical effectiveness. Ambiguous or imprecise clauses generate litigation risk and may compromise performance of the agreement. The essential clauses and drafting examples are presented in our guide to the partners' agreement and its templates.

Prior negotiation between the parties is crucial to identify points of agreement and disagreement. This phase makes it possible to adapt the contractual stipulations to the specific objectives of each signatory.

Dispute resolution mechanisms

The inclusion of alternative dispute resolution clauses helps to secure the agreements. Mediation or arbitration procedures offer alternatives to bringing the matter before the state courts, and are often better suited to the specific features of disputes between shareholders or partners. On sources of conflict, the protection of minority holders and settlement procedures, see our analysis of disputes between partners.

These mechanisms make it possible in particular to preserve the confidentiality of sensitive information relating to the company and to use arbitrators with particular knowledge of business law.

Case law developments and outlook for 2026

Recent trends in case law

French case law shows a pragmatic approach to the interpretation of shareholders' agreements and partners' agreements. The courts generally favour a broad reading of freedom of contract, while ensuring that provisions of public policy are respected.

Recent decisions show growing recognition of party autonomy in organising relations between participants in the share capital. This development favours contractual innovation and the adaptation of agreements to the specific needs of each situation.

Adaptation to new economic issues

Changes in the economic and financial landscape necessarily influence the content of shareholders' agreements and partners' agreements. The emergence of new methods of financing, the acceleration of digital transformation and environmental concerns generate new contractual needs.

Clauses on ESG (environmental, social and governance) matters are thus tending to develop in recent agreements, reflecting the growing importance of these criteria for institutional investors.

The legal security of these contractual instruments remains a major issue for business law practitioners. Assistance from a legal adviser makes it possible to optimise the drafting of agreements and to prevent later litigation risk.

Frequently asked questions (FAQ)

What is the main difference between a shareholders' agreement and a partners' agreement?

The distinction lies essentially in the type of company concerned: the shareholders' agreement applies to companies limited by shares (SA, SAS), whereas the partners' agreement concerns companies with partnership interests (SARL, SCI, SNC). The legal mechanisms and the objectives pursued remain similar.

Must a shareholders' agreement be signed by all the shareholders?

No, a shareholders' agreement may be entered into between only some of the shareholders. Only the signatories are bound by its provisions, but certain clauses may require the accession of the majority or of all of the shareholders in order to be effective.

Can the clauses of a partners' agreement contradict the articles of association?

No, the stipulations of the partners' agreement cannot derogate from the provisions of the articles of association or from the mandatory rules of company law. In the event of conflict, the articles of association and the law prevail over the agreement.

What is the maximum term of a shareholders' agreement?

There is no statutory maximum term for a shareholders' agreement. It may be entered into for a fixed or an indefinite term, according to the wishes of the parties.

How can the undertakings given in a partners' agreement be enforced?

In the event of non-compliance with the undertakings, the signatories may apply to the courts for specific performance or damages. Penalty clauses and arbitration mechanisms reinforce the effectiveness of the agreement.

Can an agreement provide for the exclusion of a partner or shareholder?

Yes, subject to certain strict conditions and respect for the rights of the defence. Exclusion clauses must be drafted precisely and provide procedural safeguards in order to be valid.

Are the agreements enforceable against heirs on the death of a signatory?

Whether the agreement passes to the heirs depends on its express stipulations. Certain personal clauses lapse on death, whereas others, such as pre-emption rights, may pass to successors.
