A French carve-out moves at the speed of the CSE.

Section 01

Employee transfer under Article L1224-1.

A transfer of an autonomous business in France triggers Article L1224-1 of the Code du travail. Employment contracts of the transferring activity pass to Newco automatically, on existing terms, with seniority preserved. The principle is protective and broadly applied by the French courts, so the buyer plans on inheriting the workforce attached to the activity rather than selecting individuals.

Collective status is part of the inheritance. Industry and company collective agreements, the conventions collectives, continue to apply, and where the applicable agreement changes a survival and adaptation period follows. Acquired advantages built up under company practice can persist, so the buyer maps the real cost of the transferring terms during diligence.

France protects employees strongly against transfer related dismissal. Restructuring connected to the transfer is constrained and procedurally heavy, so any headcount plan is treated as a separate, properly consulted process rather than something bundled into the carve-out.

For the TSA, the transferred employees often keep operating seller systems through transition. The agreement fixes who directs them and how the buyer avoids inheriting a liability created by a seller instruction during the shared period.

Section 02

Payroll, URSSAF, and social charges.

French payroll is complex and the employer social charges are high, commonly around 40 to 45 percent on top of gross salary. Newco registers with URSSAF for social contributions and files the monthly DSN, the declaration sociale nominative, which consolidates social reporting into a single return. The payslip itself is heavily regulated and itemised, so the payroll engine must be configured precisely.

The 35 hour working week, paid leave accrual, and the various mandatory employee benefits shape both cost and configuration. A French payroll stand-up is not a Day One task for most buyers, so a seller run payroll TSA for several cycles is the norm while Newco builds or contracts its own capability.

Supplementary pension and provident schemes, retraite complementaire and prevoyance, transfer with the employees and carry contribution obligations the buyer confirms during diligence. Mutuelle health cover is a further mandatory layer to replicate.

The buyer holds the payroll TSA to cost-plus or fixed-fee with audit rights and a defined exit date, resisting any blended charge that hides the underlying URSSAF and provider costs.

The buyer also confirms the status mix of the transferring population, because the distinction between cadre and non cadre staff drives different collective terms, pension contributions, and notice entitlements. Misreading that mix understates the real cost of the transferring workforce and the severance exposure Newco carries.

Section 03

Data protection and the CNIL.

France applies the GDPR with the Loi Informatique et Libertes, supervised by the CNIL, one of the more assertive European regulators. Employee and customer data that Newco holds, or that the seller processes for Newco during the TSA, needs a lawful basis, a clear controller and processor map, and appropriate security for the transition.

The works council has consultation rights over data processing and monitoring systems that affect employees, so introducing new HR or IT tooling for Newco intersects with the CSE process described below. The buyer aligns the data workstream with the consultation calendar to avoid standing up a system the committee has not yet reviewed.

During the TSA the seller processes Newco data in shared systems, which requires a processor agreement with security and deletion obligations at exit. Transfers outside the EU need a valid mechanism, and the CNIL takes transfer compliance seriously.

A data protection impact assessment for the migration is both prudent and the evidence the CNIL would expect if a transition incident arose.

Section 04

Consultation and the social and economic committee.

The comite social et economique, the CSE, must be informed and consulted before a decision that affects the organisation, economics, or employment of the company is finalised. Crucially, the consultation precedes the final decision, and the committee can commission an expert at the company expense, which extends the timeline. A carve-out that touches French employees is paced by this process.

The information given to the CSE must be complete and accurate, and the committee issues an opinion within set deadlines. Rushing or shortcutting the process risks a delit d entrave, the offence of obstructing the committee, which carries real penalties and can delay the transaction.

For the buyer the practical effect is sequence and duration. Newco communications and system rollouts wait until the consultation has run, and the seller TSA is sized to cover the period until the French organisation is fully stood up.

The discipline mirrors the German works council dynamic, and buyers operating across both plan the German consultation and the French CSE on a single integrated calendar.

Section 05

TSA scope, cutover, and cost discipline.

The French TSA scope covers payroll and social administration, IT and identity, finance, and facilities, each with a clear description, a service-level target, and a price held to cost-plus or fixed-fee. The buyer demands line item pricing because French cost allocations can carry overhead and provider margins that do not belong to Newco.

Cutover is sequenced and gated. Payroll cuts after a clean parallel and a DSN dry run, IT after a tested migration and any required CSE review, finance at a period close. Each step carries a reconciliation gate and a rollback trigger.

Cost discipline is set before signing. The buyer benchmarks the seller charges against real cost, removes unjustified mark-up, and structures exit fees that fall over the term so the incentive favours an early, clean exit even where the consultation extends the schedule.

A disciplined French separation leaves Newco running its own URSSAF registered payroll, its own consulted systems, and its own data estate under the CNIL, with the seller dependency closed on agreed terms. That outcome starts with a pre-signing review that scoped the TSA before leverage shifted.

A further French point is the role of the labour inspectorate and the protected status of certain employee representatives, whose transfer or any change to their role can require administrative authorisation. The buyer identifies protected employees early so the carve-out does not stall on a single authorisation the team did not anticipate.

FAQ

Questions buyers ask before signing.

What law transfers employees in a French carve-out?

Article L1224-1 of the Labour Code transfers the employment contracts of the activity to Newco automatically, on existing terms with seniority preserved. The courts apply it broadly, so the buyer plans on inheriting the workforce attached to the transferring activity.

Why does the CSE consultation drive the timeline?

The social and economic committee must be consulted before the decision is finalised, and it can appoint an expert at company cost, which lengthens the process. A carve-out touching French employees is paced by this consultation, so the TSA is sized to cover it.

How high are French employer social charges?

Employer social contributions commonly run around 40 to 45 percent on top of gross salary, administered through URSSAF and reported monthly via the DSN. This cost and the payroll complexity usually mean a seller run payroll TSA for several cycles.

Who regulates data protection in France?

The GDPR applies with the Loi Informatique et Libertes, supervised by the CNIL. The TSA needs a processor agreement for seller processing of Newco data, and new monitoring systems intersect with the CSE consultation rights.
