Trial Period: Legal Duration and Termination

Introduction

The trial period is one of the most scrutinised clauses during hiring. It allows the employer to evaluate the employee's skills, and the latter to assess whether the position suits them. Yet its rules — maximum duration, renewal conditions, notice periods in case of termination — are often poorly understood, exposing companies and employees to costly disputes. This article reviews the legal framework applicable in 2026, pitfalls to avoid and how electronic signature for HR transforms documentary management from onboarding to the end of the probation period.

Legal Duration of Trial Period According to Contract Type

The maximum duration of the trial period is set by French Labour Code, with distinct ceilings depending on professional category and contract nature.

Fixed-term Contract (CDI): Legal Ceilings by Category

For an indefinite-term contract (CDI), article L1221-19 of the Labour Code sets the following maximum initial durations:

• Workers and employees: 2 months

• Supervisors and technicians: 3 months

• Executives: 4 months

These durations may be reduced by collective bargaining agreement or company agreement, but they can never be extended beyond the legal ceilings — except through expressly planned renewal. It is important to note that a collective convention may set lower durations: in such case, the norm most favourable to the employee applies.

Fixed-term Contract (CDD): A Proportional Logic

For a fixed-term contract (CDD), the trial period duration is proportional to the contract duration. Article L1242-10 of the Labour Code provides:

• CDD of 6 months or less: 1 day per week of contract, limited to 2 weeks

• CDD exceeding 6 months: 1 month maximum

No renewal of the trial period is possible for a CDD, unlike a CDI.

Temporary Work Contract and Special Cases

Under a temporary work contract, the trial period duration follows the same proportional rules as the CDD. For apprenticeship contracts, the first 45 days — consecutive or non-consecutive actual work days — constitute a specific probation period during which either party may terminate the contract without notice or compensation.

Renewal of Trial Period: Conditions and Limits

Cumulative Mandatory Conditions

Renewal of a trial period in a CDI is not automatic. Three cumulative conditions must be met:

• A collective bargaining agreement extended must expressly provide for the possibility of renewal;

• The employment contract or letter of engagement must mention this possibility;

• The express agreement of the employee must be obtained before expiration of the initial period.

The absence of one of these conditions renders the renewal unenforceable against the employee: the initial period is deemed to terminate at its expiration, and any subsequent termination must follow the dismissal procedure.

Maximum Durations, Renewal Included

With renewal, the total durations cannot exceed:

• 4 months for workers and employees

• 6 months for supervisors and technicians

• 8 months for executives

Any contractual clause exceeding these ceilings is void as of right (Cass. soc., 3 November 2011, No. 10-18.933).

Role of Electronic Signature in Formalising Renewal

Renewal must be formalised in writing and signed by both parties before expiration of the initial period. Qualified electronic signature compliant with eIDAS regulation offers here an incontestable time-stamped traceability: date and time of signature, certified identity of the signatory, document integrity guaranteed. In case of labour court dispute, proof of the employee's agreement is thus established without ambiguity.

Termination of Trial Period: Notice Periods and Compensation

Termination at Employer's Initiative

The employer may end the trial period freely, without having to justify the decision (except discrimination or abuse of law). However, since the law of 25 June 2008 modernising the labour market, a notice period must be observed, proportional to the employee's length of service:

| Duration in Company | Notice Period | |---|---| | Less than 8 days | 24 hours | | Between 8 days and 1 month | 48 hours | | Between 1 and 3 months | 2 weeks | | After 3 months | 1 month |

If the notice period is not observed, the employer must pay a compensation allowance corresponding to the wages and benefits the employee would have received until the end of the notice period.

Termination at Employee's Initiative

The employee may also terminate the trial period at any time, observing a notice period of 24 hours if their presence is less than 8 days, and 48 hours beyond that. No severance compensation or additional notice is due in this case.

No Severance Compensation: General Rule

Termination during the trial period does not entitle the employee to legal severance compensation or notice compensation (except non-compliance with notice period). It also does not entitle them to unemployment benefits as of right, although France Travail admits opening of rights if the employee demonstrates sufficient affiliation time over prior periods.

Special Cases: Protection Against Abusive Termination

Despite freedom of termination, certain protections apply:

• Discrimination: a termination based on origin, sex, pregnancy, religious beliefs or health status is unlawful and exposes the employer to damages.

• Maternity: an employee whose pregnancy is medically established benefits from specific protection: termination during the 10 weeks following notification of pregnancy is presumed abusive.

• Workplace accident: case law of the Court of Cassation prohibits termination motivated by unfitness resulting from a workplace accident occurring during the trial period (Cass. soc., 16 February 2022, No. 20-16.057).

Securing Contractual Management of Trial Period Through Digital Means

Dematerialisation of Employment Contract

Handing over the signed employment contract constitutes the official starting point of the contractual relationship. Since law No. 2022-1598 of 21 December 2022 (transposing EU Directive 2019/1152), the employer has 7 calendar days from the start of work to provide the employee with a written document containing all essential information relating to the employment relationship, including the duration and conditions of the trial period.

Dematerialisation via an electronic signature solution for companies allows precise time-stamping of contract delivery and signature, eliminating any risk of dispute over the trial period start date. This is valuable assurance when the employee later contests having been informed of the trial clause.

Monitoring and Archiving of HR Documents

During the trial period, several documents may be generated: renewal amendment, termination letter, delivery certificate. An electronic signature workflow integrated into your HRIS guarantees:

• Complete traceability: every action is logged with certified time-stamping.

• Legal archiving: electronically signed documents are retained with their evidentiary value intact for the legal duration (5 years for documents relating to the employment contract).

• Accessibility: the employee automatically receives a copy of the signed document, in compliance with the legal information obligation.

To compare the various solutions available on the market, the comparison of electronic signature solutions will help you identify the tool best suited to your HR document volume.

Reduction of Labour Law Risks

According to statistics from the National Bar Council (2025), disputes related to the trial period represent approximately 12% of labour court cases handled in France. The most frequent reasons concern:

• The absence of a trial clause in the initial contract

• Non-compliance with the notice period

• Contestation of the termination notification date

Electronic signature resolves points 1 and 3 almost definitively: the document contains the clause, and its signature date is certified by a trusted third party. For point 2, sending the termination letter in dematerialised form with electronic receipt confirmation time-stamped constitutes irrefutable proof of compliance with the notice period.

Legal Framework Applicable to Trial Period

Reference Texts in French Labour Law

The trial period is primarily governed by articles L1221-19 to L1221-26 of the Labour Code for the CDI, and by article L1242-10 for the CDD. These provisions, arising from law No. 2008-596 of 25 June 2008 modernising the labour market, codified the maximum durations and notice periods that were previously provided only by collective conventions.

Article L1221-23 expressly states that the trial period and the possibility of renewal are not presumed: they must be expressly stipulated in the letter of engagement or employment contract. Any trial period absent from the initial contract is deemed non-existent, even if company practice had instituted it.

Evidentiary Value of Electronic Documents

Dematerialisation of HR documents rests on two fundamental legal pillars:

• Article 1366 of the Civil Code: "An electronic document has the same probative force as a document on paper, provided that the person from whom it emanates can be duly identified and that it is established and preserved in conditions such as to guarantee its integrity."

• Article 1367 of the Civil Code: electronic signature consists in the use of a reliable identification process guaranteeing its link to the act to which it attaches.

At European level, eIDAS Regulation No. 910/2014 (and its eIDAS 2.0 revision entering into force in 2024) establishes three levels of electronic signature — simple, advanced, qualified — and their legal value in all Member States. For acts presenting moderate stakes such as standard employment contracts, advanced electronic signature is generally sufficient; for high-stakes acts (dismissal, settlement), qualified signature (highest level, compliant with ETSI EN 319 132 and ETSI EN 319 412 standards) offers the highest presumption of reliability.

Protection of Personal Data of Employees

Processing of personal data in the context of trial period management is subject to GDPR Regulation No. 2016/679. The employer, as data controller, must:

• Inform the employee of data processing from contract signature (article 13 GDPR);

• Limit data retention to the necessary duration (minimisation principle, article 5);

• Guarantee the security of electronically signed documents, particularly in case of outsourcing to a signature provider (article 28 GDPR: data processor agreement mandatory).

The CNIL recommends retaining documents relating to the contractual relationship for 5 years after contract termination, corresponding to the limitation period for employment contract actions (article L1471-1 of the Labour Code).

Sanctions for Non-Compliance

Non-compliance with rules governing the trial period exposes the employer to several risks:

• Requalification: a termination occurring after expiration of an irregular trial period will be treated as dismissal without real and serious cause.

• Damages: in case of discriminatory termination, labour courts may award up to 6 months gross salary as compensation.

• CNIL fine: a GDPR violation in HR data management may result in a sanction of up to 4% of annual worldwide turnover.

Usage Scenarios: Electronic Signature Serving Trial Period Management

Scenario 1 — An 80-Employee SME in Logistics

An SME in the logistics sector recruits on average 25 operators and technicians per quarter, with high turnover linked to seasonality. Before dematerialisation, managing employment contracts and renewal amendments mobilised two HR staff for 2 to 3 days per recruitment wave: printing, postal sending, follow-up on delays, physical filing.

After deploying an advanced electronic signature workflow integrated into its HRIS, the average time for contract signature fell from 8.5 days to less than 24 hours. Time-stamped traceability eliminated three labour disputes over trial period start dates in the 18 months following deployment. HR productivity gain is estimated at 35% on onboarding administrative management, freeing time for human support of new entrants.

Scenario 2 — A 45-Employee Management Consulting Firm

A consulting firm primarily recruits executive profiles (category subject to a 4-month trial period renewable up to 8 months). The legal department had identified a recurring risk: trial period renewals formulated verbally, without written record, exposing the firm to requalifications as wrongful dismissal.

By adopting a qualified electronic signature process for renewal amendments, with automatic sending 15 days before initial period expiration, the firm eliminated this risk entirely. The system automatically generates a reminder to the concerned manager and HR director, produces the pre-filled amendment from HRIS data, and archives the original signed with complete audit trail. Result: zero disputes related to trial period renewal over the last two fiscal years.

Scenario 3 — An Employment Integration Business Group Employing About 200 Staff in Transition

An employment integration business group (GEI) manages insertion fixed-term contracts (CDDI) for approximately 200 employees in support pathways at any time. The multiplicity of hiring dates and high employee mobility made paper-based trial period monitoring particularly complex.

By dematerialising the entire contractual process via a mobile-accessible electronic signature platform, the GEI reduced contract formalisation time by 60% and eliminated document losses linked to unstable postal addresses. The employee signs directly from their smartphone, receives a secure PDF copy, and the time-stamped signature date establishes the trial period calculation. Compliance with information obligations of EU Directive 2019/1152 is automatically assured.

Conclusion

The trial period is a precise contractual mechanism, governed by strict legal rules regarding duration, renewal and termination. Poorly understood, it exposes employers and employees to costly disputes, judicial requalifications and significant financial sanctions. Dematerialisation of documentary management — employment contract, renewal amendment, termination notice — offers a concrete answer to these risks: time-stamped traceability, certified identity proof and automatic legal archiving.
