Apprenticeship contract in Alsace-Moselle: writing and registration are mandatory

You are a craftsman in Plouhinec, you hire an apprentice for your joinery workshop. Everything goes well, the young person learns the trade, you contribute on a flat-rate basis. Then one day, the social security fund demands additional contributions: your contract was never registered, it is void. A situation still faced by many employers in Alsace-Moselle today, where local law imposes strict formalities.

This decision of the Court of Cassation of 18 November 1970 (No. 69-11.464) is a cornerstone of Alsatian-Moselle local law. It reminds that, according to Article 126 of the Local Professions Code (law of 26 July 1900), the apprenticeship contract must not only be in writing but also registered in the register of the Chamber of Trades or the Chamber of Commerce. Only under these conditions is it valid and enforceable against social security bodies, allowing the employer to contribute on the reduced flat-rate basis for apprentices.

What does this obligation mean in practice? And above all, how should it be applied today to avoid penalties? Analysis of a judgment which, although over 50 years old, remains highly relevant for employers in Bas-Rhin, Haut-Rhin and Moselle.

The facts: a story that happens every day

Mr X, owner of a car garage in Châteaulin (but the case takes place in Strasbourg), hires a mechanic apprentice in 1967. He drafts an apprenticeship contract on plain paper, has it signed by the apprentice and his parents, and registers it on 3 October 1967 in the apprentice register of the Strasbourg Chamber of Commerce and Industry. So far, everything seems in order.

But the Primary Health Insurance Fund of Strasbourg challenges the validity of the contract. It argues that the employer cannot benefit from the reduced social flat-rate for apprentices because the contract was not registered in the manner required by local law. The fund demands payment of contributions based on the actual salary, much higher than the flat rate.

The case goes to court. The first judge rules in favour of the employer, but the Colmar Court of Appeal overturns this decision. Mr X appeals to the Court of Cassation. The Court of Cassation, in a clear judgment, confirms the position of the Court of Appeal: the apprenticeship contract, to be valid and entitle to the flat rate, must imperatively be in writing and registered in the register of the Chamber of Trades or the Chamber of Commerce. Failing this, the employer must contribute on the actual salary.

The judges specify that the registration carried out by Mr X was late or irregular, but the decision does not provide further details. The essential point is that the sanction is clear: no flat rate without prior registration.

The reasoning of the court — broken down

The judges' reasoning is based on a very specific legal basis: Article 126 of the Local Professions Code, derived from the law of 26 July 1900 still in force in Alsace-Moselle. This text provides that the apprenticeship contract must be in writing and registered in the register of the Chamber of Trades or the Chamber of Commerce. Only from the completion of these mandatory formalities is the contract valid and enforceable against social security bodies.

In other words, Alsatian-Moselle local law is more demanding than common French law. Elsewhere in France, the apprenticeship contract may be verbal (even if writing is strongly recommended). But in Alsace-Moselle, writing and registration are conditions of validity on pain of nullity. The Court of Cassation firmly reminds: without these formalities, the employer cannot benefit from the reduced social flat-rate for apprentices.

The judges reject the employer's argument that late registration would suffice. They consider the date of registration to be decisive: only registration before or at the time of conclusion of the contract entitles the flat rate. In this case, Mr X had registered the contract on 3 October 1967, but the date of conclusion of the contract is not specified. It appears that registration took place after the start of the apprenticeship, which is insufficient.

This decision confirms a consistent line of case law of the Court of Cassation on local law. It is neither a reversal nor an evolution, but a strict application of the text. The judges remind that local law derogates from common law and that the employer must comply scrupulously.

What this changes for you — concretely

For Alsatian-Moselle employers, this decision is a warning: every apprenticeship contract must be in writing and registered before the start of the training. Failing this, the employer risks a demand for additional contributions based on the actual salary, which can amount to several thousand euros per apprentice.

Let's take a numerical example: you hire an apprentice in Châteaulin (in Moselle) with a flat-rate salary of €800 per month. If the contract is not registered, the social security fund may demand contributions on an actual salary of €1,500, i.e. an additional cost of €200 to €300 per month. Over two years of apprenticeship, the back payment can reach €5,000 to €7,000, including penalties.

For apprentices and their families, the decision also has an impact: without a registered contract, the apprentice is not covered by social security for the apprenticeship, which can cause problems in the event of an accident at work or occupational illness. The employer bears liability.

If you are in this situation, you must check that your apprenticeship contract has been registered with the Chamber of Trades (for craftsmen) or the Chamber of Commerce (for traders). Registration must be done before the start of the apprenticeship, or at the latest within 15 days of concluding the contract (according to custom).

Four tips to avoid this type of dispute

• Draft a proper written contract: Do not rely on a verbal agreement or a simple email exchange. Use the standard model provided by the Chamber of Trades or the Chamber of Commerce. Include names, dates, duration, hours, remuneration and place of work.
• Register the contract before the start of the apprenticeship: Deposit the contract in the apprentice register of the competent chamber as soon as it is signed. Registration is free or almost free. Keep a receipt.
• Check local deadlines: Some chambers require registration within 15 days of conclusion. Check with your chamber to avoid any delay.
• Keep all supporting documents carefully: Signed contract, registration receipt, any amendments. In the event of an inspection, you will need to prove that you have complied with the formalities.

Further reading: related case law and developments

The Court of Cassation has handed down several judgments to the same effect, including:
- Cass. civ. 2e, 5 November 1969: same solution for an unregistered contract.
- Cass. soc., 14 January 1971: confirmation that registration is a condition of validity of the apprenticeship contract in Alsace-Moselle.

The trend of the courts is consistent: local law is interpreted strictly, with no possibility of retroactive regularisation. The judges consider registration to be a substantive formality, not a mere administrative formality. This means that even late registration, a few days after the start of the apprenticeship, can be penalised.

For the future, there is no indication of relaxation. Alsatian-Moselle local law is protected by the Treaty of Frankfurt and specific provisions. Employers must therefore incorporate this obligation into their recruitment process.

Summary and next steps

FAQ:

• Can I hire an apprentice without a written contract in Alsace-Moselle? No, writing is mandatory on pain of nullity of the contract and loss of the social flat rate.
• What if I already have an unregistered contract? Contact your Chamber of Trades or Commerce immediately to regularise. But beware, regularisation may not be retroactive.
• What is the deadline for registering a contract? Ideally before the start of the apprenticeship. Some chambers tolerate 15 days, but it is better not to wait.
• What are the penalties for failure to register? The employer must pay contributions on the actual salary, with increases and late payment penalties.
