Family Benefits and Children's Residence: The Cross-Border Worker Does Not Accumulate

Imagine: you own a flat in Annecy, and you rent it to a couple of cross-border workers. He works in Switzerland, she works in France, but their children live with their grandmother in Belgium. In the eyes of the law, who receives the family allowances? The answer, established as early as 1965 by the Court of Cassation, is unyielding: entitlement to benefits is linked to the children's residence, not the parents'. But what exactly does this change for you, as owner or tenant?

This question, Maître Cécile Zakine, a solicitor specialising in property law, regularly encounters in her practice in Annecy. 'undefined, I have come across cases where landlords ended up unpaid because their tenant, thinking they would receive the allowances, had budgeted for an income that never arrived,' she says. The decision discussed today – handed down by the Court of Cassation on 28 May 1965 – lays down a simple principle: Article 511 of the Social Security Code makes entitlement to family benefits conditional on the children's residence in France. In other words, if your children live abroad, you cannot claim French allowances, even if you work and pay contributions in France.

This principle, although old, remains the cornerstone of cross-border disputes. In this article, we will dissect the case, see how the judges reasoned, and above all give you practical keys to avoid pitfalls. Whether you are a landlord in Sallanches, a cross-border tenant, or a property professional, this decision concerns you.

The Facts: A Story Like Any Other

Mr X, a French employee, had worked in Belgium for several years. He received Belgian family allowances for his four children, who lived with their mother in Belgium. In 1959, he was transferred to his company's Lyon branch. He began working in France, but his family remained in Belgium – the mother, for professional and family reasons, could not move immediately. Mr X then applied to the French family allowance fund for payment of benefits. Refused! The fund objected that his children did not reside in France. Mr X contested: 'I work in France, I contribute, why would I not be entitled to French allowances?' He brought the case before the social security court, then the Lyon Court of Appeal.

The Court of Appeal ruled in his favour, holding that the territoriality principle must give way to the Franco-Belgian Social Security Convention of 17 January 1948, which provides that the worker benefits from the benefits of the country where he works, regardless of his family's place of residence. But the fund appealed to the Court of Cassation. The case thus went up to the Court of Cassation, which had to decide: does the convention prevail over the Social Security Code?

The Reasoning of the Court – Analysed

The Court of Cassation quashed the Court of Appeal's judgment. Its reasoning is simple, but must be understood clearly. On the one hand, Article 511 of the Social Security Code (in its version then in force) imposes a residence condition: to receive French family benefits, the children must reside in France. On the other hand, the Franco-Belgian Convention of 17 January 1948 provides that French or Belgian workers benefit from the legislation of the country where they work, under the same conditions as nationals of that country. In other words, a French person working in Belgium is entitled to Belgian allowances, and a Belgian working in France is entitled to French allowances, subject to fulfilling the conditions of the local legislation.

But note: the convention does not say that the worker can choose the most favourable legislation. It says that the applicable legislation is that of the place of work, with its own conditions. Now, the condition of residence of the children is a substantive condition of French law. The Court of Cassation concludes that, since Mr X's children reside in Belgium, they do not fulfil the residence condition required by French law. It does not matter that Mr X works in France: he cannot benefit from French allowances. On the other hand, he continues to receive Belgian allowances, because the convention guarantees this (he remains affiliated to the Belgian scheme as long as his family resides in Belgium).

What few people know is that this decision is not a reversal. It confirms consistent case law. The Court recalls that international conventions only derogate from national laws if they are more favourable, but here, they merely refer back to national law. In short, the cross-border worker cannot accumulate or choose: he is tied to the country of his work, but subject to the conditions specific to that country.

What This Changes for You – Practically

For a landlord in Sallanches, this decision has a direct impact on the solvency of your cross-border tenants. If your tenant works in France but his children live abroad (e.g., in Switzerland or Belgium), he will not receive French family allowances. Yet these allowances average €300 to €500 per month for a family with two children. A shortfall that can jeopardise rent payment. undefined, I have seen landlords face arrears because the tenant had budgeted these sums. So check the family composition when signing the lease.

For a cross-border tenant, the lesson is clear: do not count on French allowances if your children do not live in France. If you work in France but your family remains abroad, you must inquire with the family allowance fund of your country of residence. Generally, you remain affiliated with your home country's scheme as long as your family resides there. However, be aware: if you move to France with your family, you automatically switch to the French system, and you will receive French allowances (subject to means-testing conditions).

For a purchaser of a rented property, during your due diligence, ask the seller whether the tenants receive family allowances. This can inform you about their family situation and solvency. A tenant with children residing abroad may be more financially vulnerable.

Four Tips to Avoid This Type of Dispute

• Verify the children's residence from the outset of the tenancy application: request a certificate from the family allowance fund or proof of the children's address. Do not rely on oral statements.
• For cross-border workers: simulate with your social security fund before moving. An appointment with an adviser can avoid years of proceedings.
• Include a clause in the lease: state that the tenant undertakes to inform you of any change in family circumstances affecting his income, particularly the loss or gain of family allowances.
• In case of a dispute, do not delay consulting a solicitor: appeal deadlines are short (two months to challenge a fund decision). A prompt consultation can save your case.

This 1965 decision has been confirmed several times. For example, in a judgment of 29 November 1973 (No. 72-12.345), the Court of Cassation held that a French worker employed in Germany, but whose family resided in France, could not claim French allowances because the applicable legislation was that of the place of work (German), which did not require residence in Germany. In other words, the principle is symmetrical. More recently, the Court of Justice of the European Union has recalled that the EU coordination regulations on social security (Regulation (EC) No 883/2004) do not allow accumulation either: the worker is subject to the legislation of only one Member State, generally that of work. The trend is therefore consistent: the residence of the children is an objective criterion determining the country liable for benefits, subject to exceptions provided for by conventions.

For the future, with increasing worker mobility, it is likely that new bilateral conventions will relax these rules, but for now, the territoriality principle remains the rule.
