A crying baby, even at night, is not in itself an abnormal neighbourhood nuisance under French law. The courts treat occasional, unforeseen noise from children as one of the normal inconveniences of living in a block of flats. Parents do, however, need to act when excessive noise keeps recurring, and all the more so at night.
The question of “crying baby and neighbours” worries many new parents living in flats. It rarely ends up in court. It is almost always settled with a few words exchanged on the stairs, provided you know the rules and don't let the annoyance build up in silence, on either side.
What does the law say about a baby crying?
No French legal text specifically covers a newborn's crying. The law reasons in terms of an abnormal neighbourhood nuisance (trouble anormal de voisinage). According to the factsheet on behavioural noise from Service-Public, the French government's official information website, checked on 24 October 2025, a noise nuisance is a disturbance that goes beyond the ordinary inconveniences of life in a building or neighbourhood.
Three criteria are used to assess it:
- The intensity of the disturbance felt.
- Duration and repetition: a one-off nuisance carries less weight than one that keeps coming back.
- The local context: a noise tolerated in a dense city may be judged abnormal in a quiet neighbourhood.
The Code civil (French Civil Code) sets out the principle in Article 1253: you are liable for abnormal nuisances you cause to your neighbours. The same factsheet points out that you are responsible for noise made by your child, just as for noise from your pet or your appliances.
And at night?
Night-time disturbance (tapage nocturne) covers the period from 10 pm to 7 am. It is the only national time slot set by law. Service-Public stresses that, conversely, there are no hours when noise is always allowed: a nuisance can occur at any time of day. Night-time disturbance is punishable by a fine of up to €450, with a fixed penalty of €68 if paid promptly.
These penalties target behaviour, not a newborn who wakes up. A baby's crying falls first and foremost under the normal noise described above. Parents' responsibility concerns what they do, or fail to do, about noise that goes on.
What the courts take into account
The Centre d'information sur le bruit (the French noise information centre) has commented on a ruling by the cour d'appel d'Angers (Angers Court of Appeal) dated 28 February 2023. It clearly shows where the line lies between normal noise and abnormal nuisance.
In this case, tenants had their lease terminated. Mediators had observed on site running, footsteps and banging on walls and floors, repeated over several months. The nuisance exceeded the level accepted in shared housing. It had continued despite a written warning, visits from mediators and a formal notice (mise en demeure).
The court rejected the argument that you cannot stop children from crying, shouting or running. It asks parents to find “the right balance”, by day and by night. The commentary also recalls older case law: sudden, accidental or unforeseen noise from children does not constitute an abnormal nuisance.
Two other points stand out. Poor sound insulation between two homes cannot be blamed on the neighbouring family, according to a 2020 decision by the cour d'appel de Paris (Paris Court of Appeal). And a single witness statement is generally not enough: the courts expect objective, consistent findings.
In practice, a newborn's crying, even when it is frequent for a few weeks, counts as normal noise. What tips a situation over is doing nothing about repeated, avoidable noise: an older child running or jumping every evening, repeated thuds on the floor, a loud television.
This article describes the general framework and is no substitute for legal advice tailored to a specific situation.
Crying baby and neighbours: how do you defuse things before they turn sour?
Most tensions stem from a misunderstanding. The neighbour hears crying without knowing there is a newborn, or imagines neglect. The parents, for their part, feel judged every time the baby wakes at night. A few simple gestures change the atmosphere.
- Let them know as soon as the baby is born, with a note in the entrance hall or a few words on the landing. Knowing a baby has just arrived makes the crying easier to accept.
- Offer to talk about it if a neighbour seems annoyed, rather than waiting for a curt remark.
- Explain without justifying yourself: crying is how a newborn communicates, and parents respond to it.
- Thank an understanding neighbour. It is often the best protection for the months ahead.
Why newborns cry, and what helps soothe them, is explained in detail in our article on newborn crying.
Reducing noise transmission without aiming for silence
Aiming for complete silence is pointless and exhausting. It is, however, possible to limit what travels through walls and floors.
Where to put the cot
Where possible, place your baby's cot against an interior wall rather than the party wall or above the neighbours' bedroom. The same logic applies to the play corner. Our article on how to set up a small flat with a baby gives more ideas for limited space.
Impact noise on the floor
Once your baby is walking, it is no longer the crying that bothers the flat below the most, but the knocks: toys falling, running, jumping. That is exactly the kind of noise the judges took into account in the Angers case. A thick covering on a hard floor absorbs some of these impacts. A large 150 × 200 play mat made of foam therefore doubles as a play area and a shock absorber.
Noisy times of day
Ball games, toy trucks on wheels or the hoover can wait until mid-morning. Building work, for its part, often follows hours set by a municipal order (arrêté municipal). Our guide to building work with a baby looks at the question the other way round, when it is the family putting up with the noise.
If a neighbour complains: what to do
Service-Public describes a step-by-step approach for any neighbour dispute. It applies both ways.
- Talking: discuss it directly and calmly, ideally not in a moment of tension.
- A simple letter, then a letter sent by recorded delivery if the nuisance persists.
- The conciliateur de justice, a free court conciliator, or a mediator, who charges a fee. An attempt at amicable settlement is compulsory before going to court.
- The landlord or the managing agent: an owner is responsible for nuisance caused by their tenant, and the building's co-ownership rules may regulate noise.
If you receive a letter, reply to it. The Angers ruling shows that failing to react to the first complaints weighs heavily. Explaining the situation, saying what you are putting in place and suggesting a meeting is often enough to calm things down.
When the crying becomes hard to bear
Pressure from neighbours sometimes adds to tiredness and crying that won't stop. If you feel you are losing patience, put your baby down safely in their cot, on their back, and leave the room for a few minutes. Never shake a baby. Our article on shaken baby syndrome lists the numbers to know and explains why it matters to ask someone to take over.
An annoyed neighbour is never a reason to leave a baby to cry alone, or to silence them at all costs. The child comes first, then your own rest.
When it's the older children
With an older sibling, things change. A 3- or 4-year-old running down the hallway at 9 pm is a noise parents can do something about. Winding down calmly at the end of the day, keeping physical games for outdoors or the park, and wearing slippers at home all meet the “right balance” the judges ask for. If both children share a room, our article on baby and older sibling in the same room helps you organise staggered bedtimes.
Key points
- A baby's crying is, in principle, part of the normal noise of living in a building.
- An abnormal nuisance is judged on intensity, repetition and context, and on how the parents respond.
- Letting the neighbours know as soon as the baby is born defuses most tensions.
- With a child who walks, impact noise on the floor matters more than crying.
- If there is a complaint, talking and conciliation come before any legal action.
