Company conversion — SARL, SAS, SA
Company conversion lawyer in Paris: from SARL to SAS, or new governance.
Fundraising, BSPCE founder share warrants, a change in the director's social security regime: a conversion accompanies a change of strategy, and a company conversion lawyer in Paris checks that unanimity, the conversion auditor's report and express approval of the valuation, which decide its validity, are secured.
Converting into an SAS requires the unanimity of the shareholders: each shareholder's written agreement is secured before the meeting is called, not at the meeting.

Lawyer at the Paris Bar — company law and corporate structuring.
A conversion is justified by strategy: opening up the capital, BSPCE founder share warrants, simpler governance, a change of social security regime. A conversion into an SAS requires unanimity; from an SARL into an SA, the majority required to amend the articles (Article L. 223-43). The conversion auditor prepares a report whose valuation must be expressly approved, on pain of nullity. For tax purposes, a conversion between companies subject to corporate income tax is neutral; a change of tax regime counts as a cessation of business.

SARL to SAS: unanimity
Conversion into an SAS is decided unanimously by the shareholders under Article L. 227-3 of the French Commercial Code (Code de commerce): no minority shareholder can be compelled, and no provision of the articles can derogate from this.
The auditor's report
For a conversion into a company limited by shares, a conversion auditor assesses the value of the assets and any special benefits (Article L. 224-3); express approval of the valuation is a condition of validity.
Continuity to be checked
The legal entity continues under Article 1844-3 of the French Civil Code (Code civil), but the director's social security regime changes, the tax position may change and intuitu personae contracts may have to be renegotiated.
The rules
Unanimity, report, express approval
Four rules structure a conversion.
- Conversion into an SAS requires the unanimity of the shareholders (Article L. 227-3 of the French Commercial Code); into an SA from an SARL, the majority required to amend the articles, or a majority of the shares if shareholders' equity exceeds €750,000 (Article L. 223-43).
- For a conversion into a company limited by shares that has no statutory auditor, a conversion auditor is appointed unanimously or by court decision (Article L. 224-3); the report assesses the value of the assets and any special benefits.
- The shareholders' approval of the valuation must be express: a unanimous vote on the overall resolution is not enough, on pain of nullity of the conversion (Cass. com., 19 June 2024, No. 22-19.624).
- A shareholder's commitments cannot be increased without their consent (Article 1836, paragraph 2, of the French Civil Code): a mandatory provision sanctioned by absolute nullity, which can be invoked even by a shareholder who voted in favour (Cass. com., 13 November 2003, No. 00-20.646).
Timing matters as much as the decision: too early, costs without benefit; too late, a blocked fundraising or an additional tax cost. Three preliminary questions: is the target form suited to an eighteen-month horizon, are the shareholders aligned, and can the sensitive contracts — commercial lease, covenant-bearing financing, approvals — withstand the change?
Your documents
What to send for the preliminary audit
Each shareholder's position and the statement of shareholders' equity determine the timetable.
Position A
Company
- Current articles of association and shareholders' agreement
- Last two balance sheets and statement of shareholders' equity
- List of sensitive contracts: lease, financing, approvals, distribution
- Headcount and employee representative bodies (works council (CSE) consultation where applicable)
Position B
Shareholders
- Up-to-date capitalisation table
- Each shareholder's written position on the project
- Prior commitment letters where applicable
- Investor's term sheet if the conversion accompanies a fundraising
Frequent mistakes: calling the meeting without having secured unanimity in writing; converting with shareholders' equity below the share capital without prior recapitalisation.
The firm also handles:
- Conversion auditor
- Works council consultation
- Renegotiation of covenants
- Switch of the director's social security regime
The method
How the firm supports you
Skipping a step — audit, report, consultation — exposes the conversion to nullity or to a rejection by the INPI.
Step 1
Preliminary audit and strategy
Articles of association, shareholders' agreement, accounts, sensitive contracts; each shareholder's position verified and secured in writing.
Step 2
Auditor and report
Appointment of the conversion auditor, report on the value of the assets and any special benefits.
Step 3
New articles and EGM
Articles adapted to the target form, works council (CSE) consultation where applicable, proper notice of the meeting, vote by the required majority or unanimity, express approval of the valuation.
Step 4
Publication and follow-up
Legal notice, INPI filing, updating of business documents, switch of the director's social security regime, informing sensitive counterparties.
Tax: neutral between companies subject to corporate income tax; a change of tax regime (from corporate income tax to income tax or the reverse) counts as a cessation of business, with immediate taxation of profits and unrealised capital gains.

Frequently asked questions
Your questions: company conversion
Why convert an SARL into an SAS?
The most frequent reasons: opening the capital to an investor who requires preference shares, granting BSPCE founder share warrants to the first employees, simplifying governance through a single chairman, and moving the director to the employee-equivalent social security regime. The SAS offers considerable flexibility in its articles, as set out in Article L. 227-1 of the French Commercial Code (Code de commerce). It makes fundraising easier, whereas the SARL imposes more rigid rules on share transfers.
What majority is required to convert an SARL into an SAS?
Article L. 227-3 of the French Commercial Code requires the unanimity of the shareholders. No provision of the articles can derogate from it. Any shareholder, even a minority one, can block the conversion. This rule protects the shareholder who wishes to keep the SARL regime, for example a majority manager under the self-employed regime. For conversion into an SA, the majority required to amend the articles is sufficient (Article L. 223-43).
Is the auditor's report mandatory?
Yes, for any conversion into a company limited by shares (SAS, SA). If the company has a registered statutory auditor, the auditor prepares the report on the company's position and the value of its assets. Otherwise, a conversion auditor is appointed, either unanimously by the shareholders or by court decision at the request of the company's officers, under Article L. 224-3 of the French Commercial Code (Code de commerce). The shareholders' express approval of the valuation is mandatory on pain of nullity (Cass. com., 19 June 2024, No. 22-19.624).
How much does a company conversion cost?
On top of the legal notice and court registry fees (about €250 to €400), fees vary with complexity: audit, appointment of the conversion auditor, negotiation with a minority shareholder, updating of sensitive contracts. A standard SARL-to-SAS conversion is priced from €4,500 incl. VAT. Cases involving a challenge, court intervention or a family office start from €8,000 incl. VAT.
How long does a company conversion take?
Allow two to three months between the decision and effective registration. The timetable covers the preliminary audit, appointment of the auditor, drafting of the new articles of association, works council (CSE) consultation where applicable, the extraordinary general meeting, the INPI filing and BODACC publication. Any haste exposes the conversion to a procedural defect.
What is the effect of a conversion on the director's term of office?
The principle is that the term of office ends. The manager of an SARL does not automatically become chairman of the SAS resulting from the conversion. The appointment of the new director must appear expressly in the conversion decision or in a simultaneous decision. Otherwise, the company is left without a legal representative between the date the conversion takes effect and the appointment, a situation to be avoided.
What is the effect of a conversion on existing contracts?
The principle is the continuity of the legal entity under Article 1844-3 of the French Civil Code (Code civil). Contracts continue automatically. But this continuity has exceptions: intuitu personae clauses (commercial lease, distribution agreements), regulated approvals, financing with covenants, and administrative authorisations tied to the company form. Each sensitive contract must be audited and, if necessary, renegotiated.
What is the effect of a conversion on employees?
Employment contracts continue without interruption: no dismissal and no need for an amendment. The collective status (collective agreement, company agreements) is in principle maintained. However, the works council (CSE) must be consulted beforehand if headcount exceeds the thresholds. A late or forgotten consultation weakens the conversion and exposes the company to separate litigation.
Does a conversion trigger a tax cost?
A conversion between forms subject to corporate income tax is in principle tax-neutral. It does not create a new legal entity and does not entail a cessation of business. However, where it comes with a change of tax regime (from corporate income tax to income tax, or the end of an income tax option), it is treated as a cessation, with immediate taxation of profits and unrealised capital gains. A simulation is essential beforehand.
What happens if a minority shareholder refuses the conversion?
If the conversion requires unanimity (as for a switch to an SAS), the refusal of a single shareholder blocks the operation. If the blockage is manifestly contrary to the company's interest and without legitimate reason, it may be characterised as abuse of minority rights. The judge may then take the company's interest into account otherwise than by simply awarding damages (Cass. com., 14 January 1992, No. 90-13.055, the Vitama case, concerning a capital increase). Proving the abuse remains demanding.
Can a creditor oppose the conversion?
Creditors' specific right of opposition exists mainly for mergers (Article L. 236-15 of the French Commercial Code). In a simple conversion, creditors keep their rights against the converted company and may rely on unenforceability or fraud if the conversion was meant to arrange the company's insolvency. The continuity of the legal entity works in their favour (Article 1844-3 of the French Civil Code).
Does the company name have to change after a conversion?
No, the company name can be kept. The company form must, however, appear on all official documents (letterhead, invoices, the website's legal notices, contracts). An SARL that has become an SAS can no longer present itself as an SARL, on pain of a false statement. Updating commercial materials should accompany the conversion.
What happens to the share capital after a conversion?
The share capital is in principle maintained. For a conversion into an SA, the capital must be at least €37,000 (Article L. 224-2 of the French Commercial Code). If the capital is lower, a prior increase is mandatory. Shareholders' equity must also be at least equal to the share capital, failing which the conversion may be blocked.
What are the risks of nullity of a conversion?
The main risks: lack of unanimity where the target form requires it, failure to approve the valuation of the assets expressly (Cass. com., 19 June 2024, No. 22-19.624), breach of the rules on calling the meeting, and an increase in a shareholder's commitments without their consent (Article 1836, paragraph 2, of the French Civil Code, sanctioned by absolute nullity according to Cass. com., 13 November 2003, No. 00-20.646). The limitation period for an action in nullity is two years (Article 1844-14 of the French Civil Code).
Which court has jurisdiction over a challenge to a conversion in Paris?
Disputes between shareholders and those relating to the running of the company fall within the jurisdiction of the commercial court of the registered office, that is, the Paris commercial court for a company registered in the capital. The articles may provide for an arbitration clause that will displace this jurisdiction. The firm regularly pleads before this court.

What our clients say
Best real estate law and business law lawyer in Paris. A humane and attentive lawyer, with a wonderful team. Thank you, Maître KOHEN
Translated from French
Thank you to Maître KOHEN for his analyses of recent case law on fraudulent non-disclosure in property sales. It reassures me about an action for annulment that I am considering after buying a house affected by serious defects intentionally concealed by the seller and not reported by the estate agent; also defects (rising damp) characterised by spreading through-cracks and damp stains, not reported by the estate agent… Worse, defects concealed by the latter or at his instigation, under a coat of paint and by polystyrene tiles glued to the ceiling of a bedroom. And the said estate agent drafted the preliminary contract, which of course contains no information about any of these defects. Just to add that, being 77 years old and suffering from cognitive impairment, I am certain that the estate agent thought I would not be able to discover the deception and above all to establish the fraudulent intent, still less to bring legal proceedings given the complexity and length of the procedure... That is why I am opting for the criminal route, insofar as the intentional concealment of the defects by the seller and then by the estate agent amounts to the fraudulent manoeuvres of art. 313-1 of
