Selling Your Shares in a French SAS: A Seller's Guide to Process, Formalities and Tax

Selling SAS shares: negotiable instruments, with a path to walk

A French SAS share is a negotiable security — by default, its holder can sell it freely, to anyone, without the company's consent. The bylaws can layer restrictions over that default (approval clauses, pre-emption rights, lock-ups, change-of-control triggers), and a transfer made in breach of them is null by operation of law (C. com. Art. L 227-15). But where the layers have been navigated, the sale itself is remarkably light: a private agreement, a signed transfer order, an entry in the company's registers — no notary, no statutory consent, and a 0.1 % registration duty that is among the lowest in French transactional practice.

This guide walks the seller through the path: the legal default and how it differs from the SARL, the bylaws layers to clear before signing, the deal structuring, the closing mechanics — ordre de mouvement, notification, account inscription, and the exact moment ownership changes hands — the registration duty with its real exemptions and its real-estate trap, the personal-status questions (marriage regimes, indivision, protected sellers), and the extra checks for cross-border deals. The bylaws clauses themselves have their own guides — approval clauses, founder lock-ups, change-of-control clauses — and the tax side has a dedicated companion on transfer taxes; this article is the seller's map through the whole journey.

The default: free transferability — and why the SAS beats the SARL here

SAS shares are valeurs mobilières, transferred by simple book entry from account to account (C. mon. fin. Art. L 211-15). Unless the bylaws say otherwise, no organ of the company votes on the sale, no other shareholder holds a statutory right of first refusal, and the buyer's identity is nobody's business but the parties'. The contrast with the SARL is structural: a cession of parts sociales to a third party requires the consent of a majority of the shareholders in number, representing at least half of the parts sociales (C. com. Art. L 223-14 — a statutory floor the bylaws cannot remove), and carries a 3 % registration duty after a prorated €23,000 allowance, against the SAS's uncapped 0.1 %. Active cap tables incorporate as SAS — or transform into one before a sale — largely for this difference.

Two consequences of negotiability are worth knowing before pricing the deal. First, the protection is symmetrical: because shares are negotiable instruments, a completed cession of actions cannot be judicially revised for imprévision — unforeseeable changes in the company's value after closing stay where the parties left them (C. constit., decision 2023-1049 QPC of 26 May 2023) — though the parties remain free to write their own price-revision clause. Second, the bylaws are the whole game: every restriction that exists is one somebody drafted, and Art. L 227-15 gives each of them teeth — a transfer in violation of a statutory clause is null, the buyer never joins the register, and no private arrangement between seller and buyer overrides it, whatever their good faith.

Read the bylaws first: the layers between you and a free sale

The seller's first task is documentary: the current bylaws, and any pacte d'associés signed along the way. Five families of restrictions recur, each with its own guide on this site:

• Approval (agrément) clause — the sale needs the company's approval through the body, deadlines and buy-out fallback the bylaws organise (Art. L 227-14); the procedure and its traps have a dedicated guide;
• Pre-emption clause — existing shareholders (or a category of them) take the shares first, at the offered terms, through a notification-and-window mechanism;
• Lock-up (inalienability) clause — transfers of the covered shares are barred for up to ten years (Art. L 227-13), subject to the clause's carve-outs;
• Change-of-control clause — where the « seller » is a corporate shareholder being sold at its own level rather than selling its SAS shares, the L 227-17 machinery (disclosure, suspension, exclusion) is the relevant track, not a cession procedure;
• Pacte restrictions — contractual lock-ups, rights of first offer or tag/drag mechanics in the shareholders' agreement bind the seller personally; their breach yields damages rather than nullity, but a bylaws bridge clause can import the statutory sanction, and no seller wants to close into a warranty claim.

The review is not a formality: restrictions drafted for a financing round years earlier apply at face value on the day of the sale, and the SPA's representations will make the seller warrant that every applicable procedure has been or will be run. A misrepresentation there is not a technicality — it feeds the buyer's indemnity claim and, in serious cases, a fraud argument. Sellers who map the layers before approaching a buyer control the timeline; sellers who discover them at signing renegotiate under pressure.

Structuring the deal: SPA, conditions, and the sign-to-close window

The contractual backbone is the share purchase agreement — a full SPA for negotiated deals, a shorter protocole de cession for simple ones. The seller-side essentials:

• Price and payment — cash at closing, instalments, escrow, or an earn-out tied to future performance; each structure has registration-duty and capital-gains consequences the tax companion guide covers, and instalment sellers should hold a security (pledge over the sold shares, retention mechanics) until fully paid;
• Representations and warranties — on the company (accounts, contracts, employment, litigation, compliance) and on the seller's title: shares free of pledges, of undisclosed restrictions and of third-party claims, personal status accurately stated;
• Indemnification — cap, basket, duration and claims mechanics; the real negotiation of most SPAs;
• Conditions precedent — the bylaws procedures (approval, pre-emption), regulatory clearances where relevant, no material adverse change; the SPA should state precisely what happens on refusal, pre-emption or clearance failure;
• Buyer cooperation — the approval body will want the buyer's identity, beneficial ownership and profile; the SPA should oblige the buyer to supply them promptly.

Where bylaws procedures apply, the deal runs sign-then-close: the signed SPA fixes the terms, the procedures run (each window is typically counted in weeks — the bylaws say exactly how many), and closing follows the last clearance. That window is the deal's exposed flank — a buyer can use it to renegotiate, an approval body can refuse, a pre-emptor can appear at the buyer's price. The seller's protections are contractual: firm terms the buyer cannot reopen, break-fee or specific-performance language matched to the buyer's profile, and a clear-eyed read of the buy-out fallback the bylaws offer if approval fails. On buyer identity, remember that the approval decision is discretionary within the bylaws' frame: presenting a buyer the table can live with is often worth more than the last euro of price.

Closing mechanics: the ordre de mouvement and the moment ownership moves

The operational instrument of every SAS share sale is the ordre de mouvement — the transfer order the seller signs and delivers to the company. Its required content is precise: the date of the transfer, the seller's account to be debited, the number of shares in words and figures and their nature, and the identification of the buyer's account to be credited or created. The formalities of C. civ. Art. 1376 apply: the seller signs beneath the quantity written out in their own hand, in words and figures. A standardised AFNOR model exists (NF K 12-500), though any complete written form works — the Cour de cassation has even accepted a signed Cerfa tax form as a valid ordre de mouvement where it carried all the information needed for the registers (Cass. com. 18 September 2024, n° 22-18436). Two limits to keep in mind: the order is the performance of the seller's delivery obligation — signing it is the seller's task alone (Cass. com. 24 May 2011, n° 10-12163) — but it carries no presumption of ownership; it is at most a beginning of written proof of the cession (Cass. com. 3 November 1983, n° 82-10294), which is why the SPA, not the order, is the document that proves the deal.

Notification and inscription. The seller notifies the company of the deed or the order, showing the transfer date precisely — by registered letter with acknowledgment, by delivery against receipt, or by huissier. The company then verifies what it must: that the signatory has capacity (all co-owners, or a mandate, for shares in indivision), that the shares are transferable under the bylaws and not pledged — but not whether the parties' consent was real. It then moves the shares by book entry from the seller's account to the buyer's (C. mon. fin. Art. L 211-15), opening an account for a new shareholder, with the entries identifying the holder, the quantity and nature of the shares, and any dismemberments or restrictions attached. If the company refuses to record an apparently regular order, the buyer can obtain the inscription in summary proceedings — where there is urgency and the company holds an order signed by the seller — even amid a dispute over the cession's validity (Cass. com. 16 September 2008, n° 07-17892). Non-listed companies can run the same process on a shared electronic-recording device — a blockchain-type DEEP — with identical effects (Arts. L 228-1 and R 228-10).

The moment of transfer. Ownership passes at the inscription of the shares in the buyer's account or the DEEP (C. com. Art. L 228-1, al. 9), the inscription being made at the date the parties fix by agreement and notify to the company (Art. R 228-10). The buyer becomes a shareholder at that inscription — updating the bylaws or convening the buyer to meetings proves nothing by itself (Cass. com. 18 September 2024, n° 23-10455) — and the same date governs the tax side: the seller's estate and capital-gains position turn on the inscription date, not the order's. From the day the cession is opposable to the company, the buyer is subrogated in all rights attached to the shares — votes and distributions — with one classic nuance on dividends: only dividends whose distribution has actually been decided count as fruits; the parties' agreement should say who takes the undecided reserves priced into the deal. In practice, closing is simultaneous: payment, signature of the order, notification, and inscription on the agreed date — no seller should part with the order before the price, and no buyer should pay before the inscription route is secured.

The registration duty: 0.1 %, its exemptions, and the 5 % trap

Cessions of shares of a French-seated SAS are subject to registration duty at 0.1 %, whether or not a deed records them (CGI Art. 726). The base is the price expressed plus any charges that increase it — or the parties' estimate where the real value exceeds price plus charges — and the duty is uncapped; a foreign tax credit can reduce it where the deed is executed abroad. Filing follows the form of the deal: a deed is registered within one month of the cession; without a deed, a special declaration 2759 is filed within the month, with an online service at impots.gouv.fr covering the standard cases. The duty is borne by the acquirer — a point the treatise instructs the parties to recite in the deed, the ordre de mouvement or a covering letter — but with a fallback both sides should know: seller and buyer are jointly and severally liable toward the tax authority for the duties and any penalties.

The statutory exemptions are specific, not thematic: buy-backs by the company of its own shares destined for employee-savings-plan members or made in the course of a capital increase (with a carve-out for L 225-209-2 buy-backs); acquisitions of shares in companies under sauvegarde or redressement judiciaire; acquisitions within a tax-consolidated group (CGI Art. 223 A); acquisitions between companies of the same group within the meaning of C. com. Art. L 233-3; operations under the merger and demerger regimes (CGI Arts. 210 A and 210 B); and operations subject to the financial-transactions tax. Anything else pays.

The trap is prépondérance immobilière: where the non-listed company's assets are — or were at any time during the year preceding the cession — principally French real estate or interests in other non-listed real-estate-rich entities, the rate is 5 % on the price plus charges imposed on the buyer (CGI Art. 726, I-2°), with the administration able to reassess on the real market value. The test looks through holding chains, ignores fixtures treated as immeubles par destination (Cass. com. 2 December 2020, n° 18-25559), and catches operating companies whose premises dominate their balance sheet. A seller pricing a deal at 0.1 % should verify the asset test before signing — fifty times the expected duty is an unpleasant closing surprise. The seller's own capital-gains position (the 30 % flat tax for French-resident individuals, treaty analysis for non-residents, participation regimes for corporate sellers) is a separate subject with its own guide: see our companion on transfer taxes for French SAS shares.

Personal status: marriage, indivision, protected sellers

Married sellers. SAS shares are negotiable securities, and that classification decides the consent question: the spousal-consent rule for alienating non-negotiable droits sociaux does not reach them, so the selling spouse signs alone and the company acts on that signature. What the marriage regime governs is the money: under the legal community, shares acquired during the marriage with community funds are community property and the proceeds fall into the community — a point the buyer will have confirmed in the representations; under séparation de biens, shares bought with personal funds sell as personal property. Family-business bylaws occasionally add a contractual spousal-consent clause — one more reason the bylaws review comes first.

Indivision and estates. Where the shares are co-owned — an unsettled estate, a dissolved community — the company must verify that all co-owners signed the ordre de mouvement or that one holds a proper mandate to sell. An unsettled succession deserves particular care: heirs' claims can surface after closing, and the buyer's counsel will ask for the succession documents or the partage before releasing funds.

Protected sellers. A minor's shares are sold through their legal representatives, with judicial authorisation required for the significant acts of disposition the protection regimes reserve to the judge; an adult under curatelle or tutelle sells with the participation of the curateur or tuteur, the sale being vulnerable without it. In all protected configurations, build the authorisation timeline into the deal calendar — the judge's schedule does not follow the SPA's.

In every case the SPA's representations close the loop: the seller confirms their status — marital situation and regime, capacity, absence of protection measures, clean title — and carries the risk of what they did not disclose.

Cross-border sales: screening, filings and the registers

A foreign buyer — or a foreign seller — adds gates before the ordinary path, not a different path. Foreign-investment screening: acquisitions of control in the protected sectors (defence, critical technologies, sensitive infrastructure and data, among others) need prior authorisation from the French Treasury; the analysis turns on the company's activity and the buyer's chain of control, and it belongs at term-sheet stage, since a covered closing without clearance is unwound at the acquirer's risk. Competition and sectoral clearances: merger-control thresholds rarely catch secondary sales but must be checked; regulated activities (finance, insurance, health) have their own change-of-control approvals. Tax: a non-resident seller's French exposure on the gain depends on the treaty and the participation's size, real-estate-rich companies again receiving special treatment — the companion tax guide covers the grids.

On the French side of the paperwork, three registers matter after closing. The company's own share accounts and movements register carry the inscription that made the buyer an owner. The beneficial-owners register (registre des bénéficiaires effectifs) must be updated through the guichet unique where the sale changes who ultimately holds or controls 25 % or more — a filing sellers forget because it is the company's, not theirs, but one buyers now chase because their banks ask for it. And the Kbis itself does not list shareholders — a sale changes it only where an officer changes with it — so foreign counterparties wanting proof of the new ownership rely on a certified extract of the share accounts or a company attestation, not on the Kbis. Cross-border closings add the practical layer: certified translations where the foreign jurisdiction requires them, apostilles for documents travelling outward, and payment mechanics that land the price against the inscription, not before and not after.
