Judicial establishment of paternity is a legal procedure that allows a child to officially establish a parentage link with a man who has not voluntarily acknowledged paternity.
This procedure primarily concerns children born outside marriage, but it may also apply in other specific situations.
Below is a clear and accessible overview of the key rules governing judicial paternity actions in France.
1. What is judicial establishment of paternity?
Judicial establishment of paternity refers to the right of a child, or the child’s legal representative, to apply to the court for a judicial declaration of paternity, even where the alleged father has not voluntarily recognized the child.
The purpose of this action is to establish legal parentage and to enable the child to benefit from all rights arising from filiation, including:
-
-
- the right to bear the father’s surname;
- parental authority;
- child support obligations;
- inheritance rights.
-
2. Who may bring an action to establish paternity?
The action to establish paternity is reserved exclusively to the child.
If the child is a minor, the action is generally brought by the mother acting on the child’s behalf.
If the child is of legal age or emancipated, the child may act personally.
The alleged father must be a party to the proceedings. If he is deceased, the action is brought against his heirs.
3. Conditions for bringing a judicial paternity action
Since the ordinance of July 4, 2005, French law no longer imposes restrictive conditions for bringing an action to establish paternity.
It is sufficient to demonstrate that the man designated in the proceedings is the child’s biological father.
There is no longer any requirement to present prior evidence or serious presumptions before the court agrees to examine the claim.
4. How is paternity proven before the court?
Paternity may be proven by any lawful means. In practice, courts most frequently order a biological expert examination, namely a DNA test.
An unjustified refusal to submit to DNA testing may be interpreted by the court as an indication of paternity or non-paternity, depending on the circumstances and the other evidence in the case.
5. Legal effects of judicial establishment of paternity
Once paternity has been judicially established, the child acquires all rights arising from filiation with the father, including:
-
-
- surname;
- parental authority;
- child support;
- inheritance rights.
-
The father’s name is then entered on the child’s birth certificate.
6. Specific situations and particular cases
-
-
- If the alleged father is deceased: the action may be brought against his heirs. In the absence of heirs, or where heirs have renounced the estate, the proceedings may be directed against the Public Prosecutor.
The court may order biological testing on close relatives of the deceased (siblings, parents) to establish filiation. - Medically assisted reproduction (MAR / ART): where a man has consented to medically assisted reproduction but failed to recognize the child, paternity may be judicially established based on the consent given to the reproductive process, rather than on biological truth.
- If the alleged father is deceased: the action may be brought against his heirs. In the absence of heirs, or where heirs have renounced the estate, the proceedings may be directed against the Public Prosecutor.

7. Stability of filiation under French law
French law places strong emphasis on the stability of filiation.
An action to establish paternity is inadmissible where another filiation link already exists, unless that existing filiation is first contested.
This rule aims to prevent conflicts of parentage and to ensure legal certainty for children.
