Witness statement for child custody: testifying in support of a parent

A friend asks you to write a witness statement (attestation de témoin) for her file before the family affairs judge (juge aux affaires familiales). Or you are that parent, and you have to explain to the people around you what they should write. Either way, the same question comes up: what goes in it?

This page does not hand you a letter to copy, and that is deliberate: ready-made templates are exactly what gets a statement disregarded. It explains what the judge reads, what sticks, and how to recount what you have seen. The full legal framework (mandatory particulars, handwritten form, identity document) is set out in our guide The witness statement (Article 202 CPC).

The judge is not asking whether they are a good parent

This is the most common mistake, and it comes from the templates circulating online: they suggest declaring that the parent is "loving", "devoted", "exemplary". But Article 202 of the Code of Civil Procedure asks for something else:

"The statement shall contain an account of the facts which its author witnessed or personally observed."

An account of the facts. Not an assessment, not a character portrait. A judge handling a custody case often reads a dozen statements, half of them from the other side, all of them flattering and perfectly symmetrical: they cancel each other out, because none of them can be checked. What survives is the precise scene someone actually saw.

Note the difference: the right-hand column is dateable, locatable, disputable. That is precisely what gives it value. A claim the other party cannot challenge teaches the judge nothing.

The facts that matter in a custody dispute

A dispute over where the children live or over contact rights is decided on everyday life, not on moral qualities. What you personally observed and that is worth reporting:

• Everyday practicalities: who collects the children from school and at what time, who cooks when you are there, who takes them to the doctor, who buys their clothes, who supervises homework.
• Handovers: late arrivals, refusals, places, times. These are dated facts by nature, and they are at the heart of most disputes.
• What is said in front of the child: words you heard, reported as closely as possible to the way they were spoken.
• The state of the child as you observed it: what you saw, never what you infer about what happened elsewhere.
• The practical arrangements you have seen: the home, the bedroom, the journey to school, when you actually went there.
• School, medical follow-up, activities: meetings you attended, appointments where you were present.

⚠️ Only what you saw or heard yourself. "Her mother told me he never came" is not a personally observed fact: it is hearsay, the judge reads it as such, and it weakens the rest of your statement. If you did not see it, do not write it, however convinced you are.

Who may testify in support of a parent

A close relation may write a statement. It is in fact the most common situation: the people who see a parent with their children are their family, their friends, their neighbours. Article 202 does not exclude relatives; it requires that the connection be declared: kinship, marriage, subordination, collaboration or shared interest.

⚠️ Never conceal that connection. A sister who presents herself as a mere acquaintance, and whose relationship later surfaces in the file, loses all credibility, and takes the parent she meant to help down with her. Once declared, the connection blocks nothing: the judge simply takes it into account.

• A new partner may give a statement, declaring their situation. It will be read with the reservations their interest in the case calls for.
• The couple's children may never testify about the grievances between their parents in a divorce or judicial separation: the rule is absolute, set out in Article 205 of the Code of Civil Procedure and Article 259 of the Civil Code. This is a different matter from hearing the child about the measures that concern them, provided for by Article 388-1 of the Civil Code — the distinction is explained in the witness statement guide.
• Professionals (teacher, doctor, childminder) are often asked and often decline: professional secrecy, duty of reserve, or simply not wanting to take sides between two parents whose child they look after. That refusal is legitimate and should not be forced.

How the witness goes about it, in practice

The mandatory particulars (full civil status, statement that it is produced in court, reminder of criminal penalties, handwriting, identity document attached) are listed in the Article 202 guide. For the account itself, a simple plan is enough:

1. Who I am in relation to the parties: how long I have known them, in what capacity, how often I see them. This is what explains why I am in a position to observe what I describe.
2. The facts, in chronological order, each dated and located. One paragraph per scene is better than one block.
3. Nothing else. No conclusion about what the judge should decide, no comment on the other parent, no attack on their morality. The witness supplies facts; it is for the judge to rule.

What it looks like once written:

"I have known Mrs X since 2019; we live on the same landing. I run into her with her two children several times a week.

On Tuesday 3 February 2026 at around 8.15 a.m., I saw her walk her son to Jean-Moulin school, as on most mornings when I leave for work at that time.

On Saturday 14 March 2026 at around 6 p.m., I was on the landing when Mr Y came to collect the children two hours late. He said in front of them, out loud: 'your mother talks nonsense anyway'."

This is not a template to copy: it is the shape an account of facts takes. If three witnesses hand in the same text with the names changed, nobody is helped.

How many statements, and the mistake that sinks them all

Three different statements, written by people who saw different things, are worth more than ten similar ones. Copy-and-paste is spotted instantly: same turns of phrase, same adjectives, same order. It gives the judge a reason to disregard the whole set, and it exposes the parent who collected them.

Do not write the statement on the witness's behalf. Quite apart from Article 202 requiring it to be handwritten by its author, a dictated statement can be heard in the reading. The parent's role is to remind the witness of dates and circumstances, not to supply their sentences.

What the witness risks, and what they do not

The line "I know that a false statement exposes me to criminal penalties" worries many witnesses. It targets lying about materially inaccurate facts (Article 441-7 of the Criminal Code), not an approximate date or a good-faith error. Writing "in spring 2026" when you no longer remember the exact day is honest and perfectly admissible; inventing a scene is not.

Nor is a witness automatically summoned: in the vast majority of family cases the written statement is enough and nobody is heard at the hearing.
