Noisy neighbours at night: loud sex, and your children can hear it

It is 9 pm, the children have just gone to bed, and through the partition wall come the sounds of the neighbours having sex. Volume is not always the issue: what weighs is that your children hear it, wonder about it or cannot fall asleep. Noisy neighbours at night or in the evening raise a delicate question, which French law handles with precise tools. A lawyer reviews your situation in 20 minutes on Avocat20min.fr.

The rule also applies in the evening, not only after 10 pm

Many parents think the law only targets noisy neighbours at night, after 10 pm. That is wrong: the evening counts too. Two texts work together.

By day and by night. Article R1336-5 of the Public Health Code provides that no noise may, through its duration, repetition or intensity, harm the neighbourhood's peace. One of these three criteria is enough, at any time. Article R1337-7 makes it a 3rd-class minor offence, up to €450.

At night. Between 10 pm and 7 am, according to service-public, the night-time noise offence of article R623-2 of the Criminal Code is added. It is enough that the noise can be heard in your home and that its author could avoid it. The fixed penalty is €68. Our article on night-time noise, the fine and the police covers the offence.

When	Applicable text	What matters
Evening, before 10 pm	Art. R1336-5, Public Health Code	Duration, repetition or intensity
Night, 10 pm to 7 am	Art. R623-2, Criminal Code	Noise that is audible and avoidable
Any time, if it goes on	Art. 1253, Civil Code	Disturbance beyond the normal inconveniences of neighbourhood

The cause of the noise hardly matters: the law treats noise as noise, whether it comes from a speaker or from someone's private life.

When your children hear sounds of intimacy

With noisy neighbours at night, this is often the heart of the problem. Cries that come back several evenings a week, just as the children fall asleep, in a bedroom next to the neighbours' own. An adult can put on headphones; a child is left alone with what they hear.

What civil law says. Article 1253 of the Civil Code, created by Law No. 2024-346 of 15 April 2024, makes liable, even without fault, whoever causes a disturbance exceeding the normal inconveniences of neighbourhood. The text does not define what is abnormal. Judges assess it with full discretion, case by case, in light of the circumstances of time and place.

In practice, several elements linked to your children can count here:

• the time: repeated cries at the children's bedtime, on school nights;
• the layout: a child's bedroom sharing a wall with the neighbours' bedroom;
• repetition: several evenings a week, over months;
• the effects: trouble falling asleep, waking up, questions from the child, confirmed by a doctor.

One honest caveat: the judge measures the disturbance against an ordinary person, not a particular sensitivity. The presence of children does not automatically turn ordinary noise into an abnormal disturbance. It does, however, provide concrete context the judge can take into account when the noise repeats and is clearly heard in your home.

What criminal law does not cover

With noisy neighbours at night, it has to be said plainly, to avoid a complaint bound to fail or a hurtful accusation. Hearing neighbours through a wall is not a sexual offence.

Indecent exposure under article 222-32 of the Criminal Code requires an act imposed on the sight of others, in a place open to public view. A sound is not enough. The text provides heavier penalties when a minor under fifteen is the victim, but still for what is seen, not what is heard.

The ground therefore stays that of noise: R1336-5 in the evening, the night-time offence at night, abnormal disturbance before the civil judge. Writing "offence" or "danger to children" in a letter would not strengthen your case and would often close the door to dialogue.

Things change, however, if a child sees something through an uncurtained window facing a shared area, or if an adult deliberately exposes them to a sexual act. In that case, call 119 or 17.

How to raise it with the neighbour, putting the children first

Noisy neighbours at night often do not know they can be heard, let alone that children sleep on the other side. Telling them, without shame or blame, settles most situations at once.

A few principles:

• Talk about the children and the noise, not about the neighbours' private life.
• Be discreet: a note under the door or a one-to-one conversation, never in front of other neighbours.
• Suggest a practical fix rather than a reproach.

Sample note:

Hello, we are your neighbours on the 3rd floor, left. Our children's bedroom backs onto yours, and in the evening, around 9 pm, they sometimes hear voices and noise from your side. We know the walls in this building let everything through and that you surely had no idea. Could you perhaps move the bed away from the wall, or be careful around those hours? Many thanks, and do tell us if our children disturb you too.

This tone works because it judges no one and offers something in return. It contains no crude word and leaves nothing embarrassing if the neighbour shows it to someone.

How to talk to your children, by age

When noisy neighbours at night wake the household, stay calm and brief: the child mostly follows your reaction. A few pointers, to adapt to your child:

• Up to 5 or 6: reassure. "It's the neighbours, those are grown-up noises, everything is fine, nobody is hurt." No need to go further.
• From 6 to 11: a simple, true answer is enough. Adults have a private life, they sometimes make noise without realising, and you are going to ask them to be careful.
• Teenagers: a frank, tactful word, with no detail. Acknowledging that it is awkward often helps more than an embarrassed silence.

If your child seems upset, sleeps badly, asks questions that worry you or changes behaviour, talk to their paediatrician or your GP. They know how to support these situations, and their opinion can also document the effect of the noise.

Practical fixes on both sides

With noisy neighbours at night, each side can act.

In your home:

• move the children's bedroom to the other side, if possible;
• gentle white noise or calm music at bedtime;
• a thick curtain, a full bookcase against the shared wall.

In the neighbours' home:

• move the bed a few centimetres away from the shared wall, add pads;
• tighten a creaking bed base, add a thick rug;
• be mindful of the children's bedtime, especially on school nights.

If you are the one being heard, these steps and a polite reply to the neighbour's note almost always end the matter.

Respecting your neighbours' privacy

You can prove noise, but not by any means. Article 226-1 of the Criminal Code punishes with one year in prison and a €45,000 fine recording private words without consent, or a person's image in a private place.

Even with noisy neighbours at night, never film inside their home and share nothing, whether on social media or in the building's group chat. Keep a dated log instead (day, time, duration, effect on the children) and take sound-level readings in your home. Our article on noise nuisance evidence lists the useful items.

Worrying screams: a different situation

Repeated shouting, sounds of blows, a child crying for a long time or calls for help have nothing to do with intimacy. They may signal violence. Do not enter the neighbour's home: call 17 or 112 if there is immediate danger, 119 for a child, 3919 for domestic violence. Our article on neighbours arguing and domestic violence explains how to react.

The steps against noisy neighbours at night

1. The note. The one that puts the children first, above.

2. A letter. If your noisy neighbours at night change nothing, send a plain letter, then a registered letter with acknowledgement of receipt, sticking to facts: dates, times, effect on your children.

3. The landlord or the managing agent. If the neighbours rent, write to their landlord. The Law of 6 July 1989 requires tenants to use the premises peacefully (article 7) and requires the landlord, after a reasoned formal notice, to use their rights to end the disturbance (article 6-1). A tenant who persists may eventually face eviction. In a co-owned building, the syndic (managing agent) can remind everyone of the building rules.

4. The police. At night, while the noise is happening, call 17. The officers' visit leaves a record.

5. The conciliateur de justice. Before a lawsuit over a neighbour dispute, the law requires an attempt at amicable settlement. The court conciliator is free, and their presence helps raise an awkward subject without an audience.

6. The tribunal judiciaire. On the basis of article 1253 of the Civil Code, the judge can order the disturbance to stop under a penalty payment and award damages. A lawyer is not mandatory up to €10,000.

When the building carries every sound

Sometimes noisy neighbours at night do nothing abnormal: a partition that is too thin or a parquet laid without underlay lets everything through. In a co-owned building, works that worsened the insulation can ground an action against whoever carried them out. If you rent, also raise it with your own landlord, who owes you peaceful enjoyment of your home.
