How a French SAS Share Transfer Actually Works: Registers, Ordre de Mouvement and the Moment Ownership Passes

The machinery behind every SAS share transfer

A French SAS share does not transfer by contract alone. The sale agreement creates the obligation; what actually moves the share is a book entry — the company debits the seller's securities account and credits the buyer's, on the instruction of a signed ordre de mouvement, and ownership passes at that inscription (C. com. Art. L 228-1, al. 9). The whole system runs on two internal registers, a one-page form with surprisingly strict formalities, and a date rule the parties themselves control. Get the machinery right and a transfer closes in a day, privately, without a notary; get it wrong and the buyer is not a shareholder at all, whatever the contract says.

This guide is the operational deep-dive: the two registers an SAS keeps and their legal status, the ordre de mouvement's required content and case law, the inscription and the exact moment ownership moves, the paper, electronic and blockchain (DEEP) formats, what happens when a transfer is defective — and how the registered-share regime differs from SARL parts. The commercial journey of a sale (restrictions, SPA, procedures) is covered in our seller's guide, and the duty in our transfer-tax guide; this article is about the registers that make the transfer real.

The two registers — and why they, not the contract, are the title record

A non-listed SAS keeps its shares in registered (nominatif) form on its own books. Two records work together. The registre des mouvements de titres is the chronological log: every issuance, transfer, pledge and cancellation, entered in sequence with date, parties, quantity and nature. The shareholders' accounts — in practice individual fiches — carry each holder's position: identity, number and class of shares, and the notations that qualify the holding: a usufruct and the usufructuary's identity (a single fiche in the bare owner's name is the usual practice), an indivision with every co-owner named, a temporary prohibition on transfer, a pledge. The entries' content is free for an SAS, but they must identify the account holder and the quantity and nature of the shares — and the restrictions practice records there are what warns a would-be buyer that the shares are not freely negotiable.

The registers' status is what makes their maintenance a legal task rather than housekeeping. Becoming a shareholder happens on these books: the buyer acquires that quality at the inscription of the shares in their account or in the movements register — updating the bylaws or convening the buyer to meetings proves nothing (Cass. com. 18 September 2024, n° 23-10455). The books are rebuttable, not sacred: an owner can show that the inscription of their shares in someone else's name is wrong by proving they never signed a transfer document, never expressed a will to sell and never received a price (Cass. com. 22 October 2002, n° 98-22772). But in every dispute — a creditor's attachment, a contested closing, a tax question on the year of transfer — the registers are the first evidence read. They are private (held at the registered office, not filed anywhere public), they can be paper, electronic or blockchain-based, and their integrity is the cap table's insurance policy.

The ordre de mouvement: one page, strict formalities

The ordre de mouvement is the seller's signed instruction to the issuing company. Whatever its medium, it must state:

• The date of the transfer — the date the parties have fixed, which will govern the inscription;
• The seller's account to be debited — identifying the transferor (or the representative signing for a corporate seller);
• The number of shares in words and in figures, and their nature — with the quantity written by the seller's own hand above their signature, the formality of C. civ. Art. 1376 that courts have applied to the form;
• The transferee's account to be credited or created — identifying the buyer precisely enough for the company to open the account of a new shareholder.

A standardised model exists (AFNOR NF K 12-500), but no form is sacramental: the Cour de cassation has accepted a signed Cerfa tax form as a valid ordre de mouvement because it carried everything needed to record the movement and credit the buyer's account (Cass. com. 18 September 2024, n° 22-18436). Three rules of case law frame the document's weight. Signing it is the performance of the seller's obligation to deliver the shares — and that formality falls on the seller alone (Cass. com. 24 May 2011, n° 10-12163). 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), so the SPA and the inscription, not the order, prove the deal. And its delivery to the company is a formal step: notification of the deed or the order — showing the transfer date precisely — by registered letter with acknowledgment, by delivery against receipt, or by huissier.

On receipt, the company checks what the law asks of it and nothing more: the signatory's capacity (for an indivision, all co-owners or a mandate to one of them), the shares' transferability under the bylaws, and the absence of a pledge — but not whether the parties' consent was real. Where the bylaws contain approval or pre-emption machinery, the inscription waits for the procedure: the entry is the company's acknowledgment that the path was cleared, and a transfer inscribed in breach of a statutory clause is null in any event (Art. L 227-15). Where the company refuses to inscribe despite holding an apparently regular order signed by the seller, the buyer can, in urgency, obtain the inscription in summary proceedings — even while the cession's validity is disputed on the merits (Cass. com. 16 September 2008, n° 07-17892).

Is your register file actually in order?

Pick the point that worries you — the check tells you what the law requires and what to fix.

The inscription: how it runs and when ownership actually moves

Once notified, the company executes the movement as a pure book entry — securities held in accounts transfer by virement de compte à compte (C. mon. fin. Art. L 211-15). The movements register takes the chronological entry; the seller's account is debited; the buyer's account is credited, or opened where the buyer is new to the table, with the identifying entries and any encumbrance notations carried across. Partial transfers leave the seller's fiche showing the residual holding; total exits close it. Practice completes the file with the company's written confirmation to the buyer — the extract or attestation their bank, their counsel and the next deal's diligence will ask for.

The date rule deserves precision, because it is the answer to most closing questions. Ownership of the shares passes at their inscription in the buyer's account or in the DEEP (C. com. Art. L 228-1, al. 9) — and that inscription is made at the date fixed by the agreement of the parties and notified to the issuing company (Art. R 228-10). The parties therefore control the effective date within the mechanics: the SPA fixes closing, the order and notification carry that date, and the inscription executes it. The consequences follow the date, not the paperwork around it: the buyer is subrogated in the rights attached to the shares — votes, distributions — from the date the cession is opposable to the company, with the classic dividend nuance that only distributions actually decided count as fruits, so the deal should say who takes the undecided reserves. The fiscal side reads the same clock: the seller's capital-gains year and estate position turn on the inscription date, not the ordre de mouvement's. And until the entry is made, the buyer is not a shareholder against anyone — the sign-to-inscription gap is the window where sellers' creditors, competing claimants and cold feet all live, which is why well-run closings collapse it to a single day.

Paper, electronic, or blockchain: the three register formats

Paper remains the small-company default: bound registers and individual fiches at the registered office, entries added in sequence, never overwritten. It is legally sufficient and operationally fragile — fires, moves and forgotten updates are the classic failure modes, and reconstitution after a loss means rebuilding the chain from deeds, orders and accounting records with the shareholders' cooperation.

Electronic registers carry the same legal effect with better discipline: timestamps, audit trails, access control, backups. The ordre de mouvement can be electronic too, signed with an electronic signature meeting the applicable standards. The operational rule that matters is uniqueness: one authoritative register, reconciled with any parallel records counsel or a cap-table platform keeps — two diverging versions of a cap table are a dispute waiting for its occasion.

The DEEP — dispositif d'enregistrement électronique partagé, the blockchain-type shared recording device opened to non-listed sociétés par actions by the 2017 ordinance and its 2018 decree — is the statutory step further: an alternative to the account inscription producing the same effects. The inscription of transferred shares in the device is made at the date fixed by the parties' agreement and notified to the company, and carries the transfer of ownership (Arts. L 228-1 and R 228-10). The device must permit identification of the holders and of the nature and number of securities held, and include an external mechanism of periodic data preservation. For an SAS with a moving cap table, the DEEP formalises what good electronic registers already do — with the transfer-of-title effect written into the Commercial Code itself. One caveat crosses all three formats: the registers are the company's books, in the president's care; a custodian or platform can administer holdings for an investor's convenience, but it does not displace the issuer's own record — and every bylaws restriction applies identically whatever the format.

Defective transfers: refusal, correction, reversal

The machinery has failure modes, each with its remedy.

A defective order. Missing content, absent handwritten quantity, a signature that does not match the account, an indivision without all signatures: the company refuses, states why, and the seller re-executes. The refusal is the system working — the company's verification duty (capacity, transferability, no pledge) exists precisely to stop these entries.

An entry that should not have been made. An inscription recording a transfer made in violation of the bylaws' clauses records a nullity: the transfer is void by operation of law (Art. L 227-15), the buyer never became a shareholder, and the register is corrected to reflect it. An inscription based on a forged or consent-less document does not create ownership either — the true holder proves they never signed a cession, never willed one and never received a price, and the inscription falls (Cass. com. 22 October 2002, n° 98-22772). Clerical mistakes — wrong quantity, misspelled holder — are corrected by a fresh entry preserving the chronology, with the supporting documents archived; registers are corrected forward, never rewritten.

A refusal that should not have been made. The mirror case: the company sits on an apparently regular order signed by the seller and will not inscribe. In urgency, the buyer forces the entry in summary proceedings, the merits dispute continuing separately (Cass. com. 16 September 2008, n° 07-17892).

Behind every corrective route sits the same discipline: keep the file. The deeds, the orders, the notifications with their dates, the company's confirmations, and a register that reconciles with the accounting — capital, classes, equity reporting. When a challenge comes years later — an heir, a divorcing spouse, a tax audit, a liquidator — the party holding the coherent file wins the evidentiary battle before the legal one begins.

The contrast: how SARL parts transfer — and why it matters at exit

SARL parts sociales are not negotiable securities, and their transfer shows it. A cession de parts requires a written deed; it becomes opposable to the company through the civil-law formalities — service by huissier or acceptance in an authentic deed, softened in practice by the deposit of an original at the registered office against a certificate — and opposable to third parties only after publication of the amended documentation at the commercial registry. Add the statutory consent requirement for transfers to third parties (a majority of shareholders in number representing at least half the parts, C. com. Art. L 223-14) and the 3 % registration duty, and the same economic operation that closes in a day in an SAS becomes a documented, published, consent-gated procedure in an SARL.

The comparison is not academic. It is one of the standard reasons growing companies transform into SAS before raising or selling: the securities-account machinery — order, inscription, parties-fixed date — is what lets French cap tables move at transaction speed. It is also a due-diligence lens: an SAS whose registers have been kept like an SARL's paper file (contracts in a drawer, no inscriptions) has given away the form's main operational advantage and must rebuild the chain before any serious buyer closes. Our guides to selling SAS shares and to the transfer-tax comparison take the exit story from here.
