The SAS president's role: powers, responsibilities and limits

SAS president: the legal framework in 2026

The president is the legally required management body of the French simplified joint-stock company (SAS). Commercial Code, Article L.227-6, grants them representation of the company towards third parties and “the broadest powers to act in all circumstances” in the SAS's name. This legal foundation sits within the chapter devoted to SAS companies, which establishes broad freedom to organise governance through the articles.

The direct consequence: although shareholders may closely regulate internal management, the president's ability to bind the company towards third parties remains highly protective of counterparties. This “internal freedom / external security” structure explains the SAS's popularity with startups.

The president's external powers: representation that is hard to limit

The principle of “broadest” representation

Externally, the SAS is bound by the president's acts, even beyond its corporate purpose, unless it proves the third party “knew” or “could not have been unaware” (art. L.227-6 Commercial Code). In practice, this is difficult to prove: mere publication of the articles does not establish that knowledge.

Clauses unenforceable against third parties

Internal restrictions in the articles (e.g. prior shareholder approval for a significant loan) protect shareholders collectively but are unenforceable against good-faith third parties. The company remains bound, and the president may incur internal liability for disregarding those limits (Legifrance, CCI Paris IDF).

Internal powers: what the articles can (and should) provide

The SAS's great strength is freedom of internal organisation. The articles may:

• Define the president's functions and, where appropriate, create other bodies (managing director, committees) and decision-making procedures;
• Require prior approval for certain acts (borrowing above a threshold, guarantees, significant asset disposals, dilutive transactions, signing or terminating strategic contracts, capex beyond a budget);
• Organise shareholder information (periodic reporting, dashboard, annual budget, cash-flow plan);
• Reserve certain major decisions to the general meeting (capital increases/reductions, approval of accounts, amendments to the articles).

To structure these safeguards effectively, see our guide to drafting SAS articles suited to a startup and coordinate them with a shareholders' agreement covering governance, liquidity and exits (essential shareholders' agreement clauses).

President, managing director and delegations

The articles may provide for additional executives (e.g. managing director) and grant them powers, or even joint or separate representation towards third parties if clearly stipulated (SAS chapter on Legifrance). Internally, for legal and criminal-law security, the president may establish written, precise and limited delegations (purpose, resources, scope, duration) to competent managers (Justice.fr).

Appointment, publicity and enforceability

The president is appointed according to the articles (shareholder decision or competent body). Effect towards third parties requires completion of statutory formalities: RCS filing and BODACC notices through the single portal. Executives and businesses can find the process on Service Public Pro.

Usual conditions: capacity, no management disqualification and, where applicable, combining the office with an employment contract within strict limits (genuine subordination and separate technical duties). For practical matters (social-security/tax status, remuneration), see the explanatory CCI Paris IDF summaries and this operational memo: SAS president: appointment, powers and remuneration.

The president's obligations and liabilities

• Civil liability: for management faults causing loss to the company or shareholders (e.g. commitments knowingly outside the corporate purpose, decisions manifestly contrary to the company's interests). The company may bring a claim or shareholders individually where they suffer personal loss.
• Criminal liability: the president may be prosecuted for economic or corporate offences (e.g. presenting or publishing inaccurate accounts, distributing fictitious dividends, obstructing shareholders' rights), in addition to general offences. See useful reminders on Justice.fr.
• Tax and social-security liability: possible for fraudulent conduct, deliberately creating insolvency or serious breaches of reporting and contribution obligations (Service Public Pro).
• Regulated related-party agreements and conflicts of interest: agreements between the company and the president (or an intermediary) are subject to a specific authorisation/approval procedure under the SAS regime, coordinated with the articles and agreement (SAS chapter on Legifrance).

Practical limits and risk areas

• Overly broad or narrow corporate purpose: an imprecise purpose complicates governance; too narrow, it increases the risk of acts beyond it known to third parties. Calibrate it precisely and update during pivots.
• Unenforceable internal restrictions: even without required approval under the articles, an act binds the company towards good-faith third parties; exposure then shifts internally to the president (art. L.227-6).
• Guarantees and security: granting a guarantee or pledging strategic assets without an articles-based approval filter creates major risk. Include a threshold and accelerated approval procedure.
• Strategic contracts and M&A: signing or terminating key partnerships, asset disposals and joint ventures must undergo a governance check. Establish robust approval traceability (useful in audits). To organise this, see how to prepare your legal data room.

Governance good practice for SAS presidents

• “Mirrored” articles and agreement: align approval lists, quorums and validation schedules. Our SAS or SARL for a startup comparison helps objectively assess needs.
• Graduated approval clauses: by threshold, act type and maturity (pre-seed, seed, Series A…). Include fast-track procedures for emergencies.
• Reporting and budget: obtain approval of an annual budget and KPIs. To anticipate costs, consult our startup legal budget by stage guide.
• Written delegations of authority: limit criminal-law risks by giving clearly defined delegations to managers with adequate resources (Justice.fr).
• Directors' and Officers' insurance (D&O): obtain cover suited to management faults and third-party claims. Check common exclusions.
• Monitoring and compliance: update articles and procedures at each product pivot or financing transaction; the general framework is outlined on Service Public Pro and Legifrance.

When opening the capital to investors, the interaction between the president's powers, investor rights and protective clauses is negotiated in the term sheet and fundraising documents. To prepare, read our guide to legal formation and structuring stages and, for financing, our content on term sheets and convertible instruments (convertible notes, BSA AIR).

Quick checklist

• Corporate purpose: precise, current and consistent with target activity.
• Approval clauses: loans, guarantees, capex, strategic contracts, key HR decisions.
• Internal procedures: approval timetable, thresholds, delegations.
• Publicity: appointment and changes filed with RCS/BODACC.
• D&O insurance: executive cover for management faults.
• Traceability: decision registers, minutes, current data room.

Quick FAQ

Can a president limit liability through a clause in the articles?

No. Clauses may regulate internal management, but do not erase executive liability for fault or reduce representation towards good-faith third parties (art. L.227-6).

Do acts beyond the corporate purpose bind the SAS?

Yes, unless it is proved that the third party knew (or could not have been unaware) of the excess. Publication of the articles is insufficient to establish that knowledge (art. L.227-6).

Is a managing director required in addition to the president?

No. However, the articles may create a managing director role and organise the distribution of powers, including representation if provided (SAS chapter).

When does the president's appointment become enforceable against third parties?

After RCS formalities and legal publication through the single portal (Service Public Pro).

What good practice applies from formation?

Draft precise articles, establish an approval matrix, implement delegations, D&O insurance and regular reporting. Use our guide to drafting SAS articles.
