Recognising a child is a legal act that officially establishes the parent-child relationship between a father and his child. This process, governed by the **Code civil**, can be carried out before or after birth. Below are the key elements to consider when drafting a paternity recognition letter, along with an adaptable template.

## When and Why Recognise a Child?
Paternity recognition establishes paternal filiation when it is not automatic (e.g., for unmarried couples). Under the **Code civil**, it may be done:
- **Before birth** (during pregnancy).
- **At birth** (during civil registration).
- **After birth** (at any time) [S4].
### Special Cases
- **Married couples**: Paternity is presumed (the child automatically takes the husband’s surname). Recognition is unnecessary unless contested.
- **Unmarried couples**: Recognition is essential to establish the legal bond between the father and the child.
- **Anonymous birth (accouchement sous X)**: If the mother gave birth anonymously, the father may notify the **procureur de la République** to initiate a search for the child’s date and place of birth [S10].

## How to Draft a Paternity Recognition Letter?
### Validity Requirements
For the recognition to be valid, the following criteria must be met [S4]:
1. **Written form**: It may be done:
- In the birth certificate.
- By deed received by a **civil status officer** (town hall).
- By **authentic instrument** (notary).
2. **Supporting documents**: The declarant must provide:
- An official ID (passport, national identity card).
- Proof of address or residence (less than three months old).
3. **Free consent**: The recognition must be voluntary.
### Paternity Recognition Letter Template
Below is an adaptable letter to submit to a civil status officer or notary:
[Your first name and surname] [Your address] [Postcode, City] [Your telephone number] [Your email]
[City], [date]
To the attention of the civil status officer [City] Town Hall [Town Hall address]
Subject: Paternity Recognition
I, the undersigned, [First name and Surname], born on [date of birth] in [place of birth], residing at [full address], hereby declare that I recognise as my child:
- Child’s surname: [Surname]
- First name(s): [First name(s)]
- Date of birth: [date] (or “to be born” if before birth)
- Place of birth: [City, Country] (if known)
I certify on my honour that the above information is accurate and that this recognition is made freely.
Done at [City], on [date]
[Signature]
### Where to Submit the Letter?
- **At the town hall**: The civil status officer records the recognition and notes it on the child’s birth certificate [S4].
- **With a notary**: Useful for joint recognition, particularly in cases of **medically assisted reproduction with a third-party donor** [S6].

## Legal Effects of Recognition
### Rights and Obligations
Once recorded, recognition produces several effects:
- **Filiation**: The child is legally linked to the father.
- **Parental authority**: The father may share parental authority with the mother (subject to applicable rules).
- **Maintenance obligations**: The father must contribute to the child’s upkeep and education (general principle of family law, not detailed in the provided sources).
- **Succession rights**: The child inherits from the father and vice versa.
### Contesting Recognition
Recognition may be challenged in court in certain cases, including:
- If the father discovers he is not the biological parent (as illustrated in a **Cour de cassation** ruling where a mother admitted in a letter that her future husband was not the father) [S2][S8].
- In cases of **defective consent** (duress, mistake).

## Frequently Asked Questions
### 1. Is paternity recognition mandatory?
No, it is **voluntary**. However, for unmarried couples, it is essential to establish the legal bond between the father and the child.
### 2. Can a child born under X be recognised?
Yes, but the process is regulated. The father must inform the **procureur de la République**, who will search for the child’s date and place of birth [S10]. If the mother maintains her anonymity, the recognition cannot be transcribed on the birth certificate.
### 3. What if the mother refuses recognition?
Recognition is a **unilateral act**: the father may recognise the child without the mother’s consent. However, if the mother contests the paternity, she may apply to the court to annul the recognition [S2][S8].
### 4. Can recognition be retroactive?
Yes, it has **retroactive effect** from the child’s date of birth (e.g., for succession rights).
### 5. Is a notary required to recognise a child?
No, recognition at a town hall is sufficient. A notary may be useful for joint or anticipatory recognition [S6].
