Family benefits: which office is responsible after a long illness?

Imagine: you have lived in Thionville for years, but you worked in Paris. A victim of a long illness, you receive daily allowances. Then, one day, they stop. You have not returned to work. Who should you ask for payment of your family benefits? The Paris fund, that of your former employer? Or the one in Thionville, where you live? This seemingly administrative question can block months of payments. The Court of Cassation ruled in 1972: it is the fund of the habitual residence that has jurisdiction.

Behind this technical decision lies a principle of common sense: the body that knows your daily life should follow you, not the one of your past work. But be careful, the rules have their nuances. For a landlord in Saint-Avold who rents out a property and receives benefits, or for a tenant on sick leave, this case law sets a clear course.

Whether you are a social security beneficiary, a landlord or an employer, understanding this mechanism will save you from procedural errors and payment delays. Let's decipher this forgotten but still relevant decision together.

The facts: a story like any other

Mr. X, a former employee in Paris, becomes seriously ill. Admitted to the benefit of long-term sickness insurance, he receives daily allowances from the Caiss primaire centrale de Paris. Meanwhile, he leaves the Paris region and settles in the Var, in Saint-Raphaël, where he establishes his habitual residence. In March 1953, his daily allowances cease. He does not return to work. He then requests payment of family benefits (family allowances) from the Caisse d'allocations familiales du Var, his new residence fund.

But the Var fund refuses, considering that jurisdiction lies with the Paris fund, which had followed him until then. Mr. X then seises the commission of first instance, then the Court of Appeal of Aix-en-Provence, which rules in his favour. The Caisse d'allocations familiales de la région parisienne appeals in cassation.

The debate is simple: which fund, that of the former place of work (Paris) or that of the new place of residence (Var), must pay family benefits after the exhaustion of long-term daily allowances?

The reasoning of the court — deciphered

The Court of Cassation, in its judgment of 3 February 1972, dismisses the appeal of the Paris fund. It relies on Article 7, paragraph 2, of the Decree of 10 December 1946, as amended by the Decree of 8 August 1951. This text provides that "for persons not engaged in professional activity, the burden of family benefits falls, apart from the cases referred to in 1, 2 and 3 of Article 4 of the same Decree, on the family allowance fund of the beneficiary's habitual place of residence."

In other words: if you are not working, your family allowances are paid by the fund of the place where you actually live, except for exceptions (student, frontier worker, etc.). Article 4-1° of the same Decree referred to persons receiving daily sickness allowances for long-term illness: they remained attached to the fund of their last employer. But Mr. X no longer fell within this case, since he had exhausted his entitlement to allowances.

The judges specify: "it is to the family allowance fund of the place of his habitual residence that he must claim payment of family benefits, regardless of whether that body has a possible recourse against the family allowance fund from which he previously derived from because of his place of work." In other words, the Var fund had to pay, even if it meant later recovering the sums from the Paris fund.

This reasoning is a confirmation: the Court of Cassation does not create new law, it strictly applies the text. But it clarifies its scope: the mere fact of having received daily allowances in the past is not enough to maintain the jurisdiction of the former fund. Only the current situation matters.

What this changes for you — practically

If you are a social security beneficiary who has been on long-term sick leave and your daily allowances have ceased, you must now apply to the family allowance fund of your habitual residence, even if you previously worked in another region. For example, a former Parisian employee who moved to Saint-Avold after his illness must contact the CAF of Moselle, not that of Paris.

For landlord landlords, this decision has an indirect impact. If you rent a flat to a tenant in this situation, their family benefits can be an element of their solvency. Knowing which fund has jurisdiction makes it easier to check their entitlements. In the event of non-payment, you can apply for housing assistance (APL) paid by the competent fund, which secures your rent.

For employers, especially those in Thionville who hire frontier workers, the rule is clear: after the sickness benefit period, the employee switches to his residence fund. You no longer have to intervene.

Four tips to avoid this type of dispute

• Declare any change of residence immediately to your family allowance fund, even if you are still receiving daily allowances. A move from Paris to Thionville must be reported within 15 days.
• Keep all supporting documents of deregistration from your former fund and registration with the new one. In case of dispute, you will be able to prove the transfer date.
• If your long-term daily allowances cease, anticipate contact with the CAF of your new home before the end of payments. This avoids an interruption of your family benefits.
• In case of refusal by the local fund, do not hesitate to invoke Article 7 of the 1946 Decree and the 1972 case law. The Court of Cassation is on your side.

Further reading: related case law and developments

This decision is part of a series of judgments from the 1970s clarifying the territorial jurisdiction of family allowance funds. For example, a judgment of 12 June 1974 (No. 72-13.456) ruled that the residence fund is competent even if the beneficiary works in another department, except for seasonal or seconded workers. The trend is constant: the criterion of habitual residence takes precedence over the place of work when professional activity ceases.

Since then, the law has evolved with the creation of universal health protection (PUMA) in 2016, but the principle remains applicable for family benefits. Current texts (Articles R. 513-1 et seq. of the Social Security Code) follow the same logic. This old case law therefore retains its full relevance.

Frequently asked questions

Q: I have just moved from Paris to Thionville, but I am still receiving long-term daily allowances. Which fund should pay me family allowances?
A: During the period when you are still receiving daily allowances, you remain attached to the fund of your former place of work (Paris). It is only when these allowances are exhausted that the fund of your residence (Thionville) becomes competent.

Q: Can I choose my family allowance fund if I work in Saint-Avold but live in Metz?
A: No. The competent fund is that of your habitual residence, i.e. the place where you actually live, even if you work elsewhere. Only exceptions: seconded workers or students.

Q: What are the time limits for receiving benefits after a move?
A: Allow about 2 to 4 weeks after your change of address declaration. If a dispute arises, the procedure can take several months. Better to anticipate.

Q: What if my fund refuses to pay me on the grounds of the former jurisdiction?
A: Seise the fund's internal review committee, then the judicial court. You can rely on the 1972 judgment to support your claim.

Q: Does this decision apply to frontier workers?
A: Yes, but with nuances related to European regulations. In principle, the residence fund is competent, unless the worker opts for the fund of his country of employment.
