Shared residence: how it is decided, how to apply for it and its effects

Published on 20/07/2026

When parents separate, shared residence (résidence alternée) — the child living in turn with each of them — often comes up in the discussion, sometimes as self-evident, sometimes as a sticking point. But is it a right? How do you apply for it? What does it concretely change for benefits, tax or maintenance? Here, in a documentary way, is what French law provides, on the basis of the texts and of the official sources.

What the law says: residence may be fixed "alternately"

It is Article 373-2-9 of the Civil Code that expressly provides for this arrangement:

"In application of the two preceding articles, the child's residence may be fixed alternately at the home of each parent or at the home of one of them."

Shared residence is therefore not the default rule: it is one of the two possible arrangements, alongside habitual residence with one parent with contact and accommodation rights for the other (see our guide The child's residence after separation). In both cases, parental authority in principle remains exercised jointly: deciding where the child lives removes no one from their life (see Parental authority).

⚠️ A stubborn misconception: "alternate" does not mean a strict 50/50. The Cour de cassation accepts that the periods of residence with each parent may be unequal (one week / two weeks, adjustments around school journeys…) while still amounting to shared residence. What counts is the arrangement adopted, not perfect symmetry.

The only criterion: the child's interest

There is no automatic right to shared residence, for either parent. Nor does French law lay down any statutory age condition (neither a minimum nor a maximum): the law sets no threshold. The judge assesses case by case, concretely, in the light of the child's interest — which explains why, for a very young child, alternation is sometimes ruled out or adjusted, not by virtue of an age rule, but in the light of their particular situation.

In deciding on the arrangements for exercising parental authority, Article 373-2-11 of the Civil Code requires the judge to take "notably" into consideration the parents' previous practice, the sentiments expressed by the child, the ability of each to assume their duties and to respect the rights of the other, expert assessments, social inquiries, and any pressure or violence. None of these criteria is ranked above the others — everything turns on the overall assessment. We set out this list in detail in our guide on the child's residence.

How to obtain it: an approved agreement or a decision of the judge

Two routes lead to shared residence:

by agreement between the parents, who may have it approved by the family court judge — the judge checks that the agreement preserves the child's interest and that consent is free (Article 373-2-7 of the Civil Code);
by decision of the family court judge, failing an agreement — seised by application (see Applying to the family court judge). A lawyer is not mandatory for residence, parental authority, contact rights or maintenance.

In the event of disagreement, the judge may also, on the basis of that same Article 373-2-9, order a shared residence on a provisional basis, for a period they determine: a genuine trial period at the end of which they rule definitively. It is a useful option where alternation is plausible but uncertain.

	Shared residence	Residence with one parent + contact rights
Place of life	In turn with each parent	Mainly with one parent
The other parent	Takes the child in their turn	Has contact and accommodation rights (DVH)
Division of time	Variable — not necessarily 50/50	Often "every other weekend + half of the holidays" (a practice, not a legal rule)
Fixed by	An approved agreement or the judge	An approved agreement or the judge
Administrative address	Only one is declared, but the tax burden is deemed shared	That of the parent providing accommodation

What weighs in the decision

Beyond the texts, certain concrete factors constantly recur in the judge's assessment — and deserve to be documented if you are applying for alternation:

the geographical proximity of the two homes (the same school, the same activities, reasonable journeys);
each parent's actual availability (working hours, organisation, capacity to accommodate);
the parents' ability to cooperate and to communicate about the child: alternation implies frequent handovers. Acute and lasting conflict is an argument often accepted against alternation. Family mediation can help demonstrate, or rebuild, that capacity for dialogue.

Documenting the reality of daily life — who does what, since when, on what schedule — often carries considerable weight. See our guides Building an evidence file for the family court judge and Preparing for your hearing before the family court judge.

Its concrete effects: benefits, tax, maintenance

Shared residence has practical consequences that are best anticipated.

Family benefits. They may be shared between the two parents. On application (Cerfa form No. 14000), each then receives half of the amount. Failing agreement, the CAF divides them automatically. Note: only family benefits (paid from two children onwards) are shared in this way; the other benefits are paid in full to the designated parent. Details on the official page Who receives the family benefits for a child in shared residence? (F21248).

Tax. Article 194 of the General Tax Code deems a child in shared residence to be "in the equal charge of each parent". The increase in the family quotient is therefore shared in half: each receives an additional quarter of a share for each of the first two children (that is, half a share for two children), and not the whole share.

⚠️ Child maintenance does not automatically disappear with shared residence. Each parent contributes "in proportion to their resources, those of the other parent, and the child's needs" (Article 371-2 of the Civil Code): if the parents' incomes are very different, the judge may set maintenance payable by the better-off parent to the other, so that the child has a comparable standard of living in both homes. See our guide Child maintenance for a child. Note also: for tax purposes, a parent cannot combine the shared family quotient and the deduction of maintenance for the same child.

How much does it cost? (new in 2026)

⚠️ Since 1 March 2026, referring a matter to the civil courts is no longer free. A legal aid contribution of 50 € (a tax stamp bought online) is due for any first-instance application before the judicial court (official presentation). But two frequent situations in family matters are exempt from it: the family court judge ruling on a parental agreement (and therefore the approval of an agreement on residence) and the protection order in cases of violence. Beneficiaries of legal aid (aide juridictionnelle) are likewise exempt (see Legal aid).

One more reason, where possible, to favour agreement: having an amicably agreed shared residence approved remains free, quicker, and lays foundations of cooperation that the judge values. And if a parent obstructs the arrangements laid down, the answer is to refer the matter to the judge, not to take justice into your own hands — keeping the child may constitute the offence of failure to return a child (see Failure to return a child).

Applying for shared residence, or defending it, is prepared with concrete material: the actual schedule of the child's presence, each parent's availability, the proximity of the homes, school and after-school organisation, exchanges between parents. This is precisely the organisational work Aridelle is designed to make easier — gathering your documents, keeping track of dated facts and preparing your questions for a professional.
