How to Establish Paternity in Mauritius

Published 30 August 2026 · Lex Aquila Advocates

In Mauritius, paternity may be recorded voluntarily through civil-status procedures or established judicially when it is disputed. Those routes should not be confused. An acknowledgement is a formal civil-status act; a contested action in recherche de paternité is decided by the Family Division of the Supreme Court, using the evidence properly placed before it.

Voluntary acknowledgement of paternity

For a child born to unmarried parents, the Civil Status Division states that both parents who wish to register the birth together must attend and sign the birth declaration. The parents’ national identity cards and the maternity certificate or attestation are among the documents required. If only one parent declares the birth, the Division explains that the child takes that declaring parent’s surname.

An acknowledgement may also be made by deed before a civil status officer. Section 60 of the Civil Status Act requires the deed to be entered in the appropriate register and a reference placed in the margin of the birth entry. This is a legal act with consequences, not an informal addition of a name to a school or clinic form.

Before using either route, obtain the full birth entry and check the child’s names, date and place of birth, the declaring parent and any marginal annotation. A maternity attestation, a baptism record or proof that an adult paid expenses may be evidence of a fact, but none should be mistaken for the current civil-status entry. Correcting a clerical error is also different from asking a court to decide disputed parentage.

Court proceedings where paternity is disputed

A person seeking a judicial determination uses the civil action known as recherche de paternité under article 340 of the Code Civil Mauricien. The Attorney-General’s Office identifies that action as one of its family-law services, and the legislation establishing the Children’s Court assigns recherche de paternité and désaveu de paternité proceedings to the Family Division of the Supreme Court.

The initiating papers must identify the parties, the child and the facts relied upon. A birth certificate, communications between the adults, evidence of their relationship during the likely conception period, financial support, photographs and witnesses may be relevant depending on what is disputed. The general guide to filing a case in Mauritius helps explain pleadings and service, but a parentage action has its own civil-status consequences.

DNA testing and other evidence

DNA evidence can be highly probative, but a private test is not a substitute for properly conducted court evidence. Identity, consent, sample collection, chain of custody and the testing laboratory all affect whether a result can be relied upon. Where proceedings are contemplated, obtain directions or advice before arranging a consumer kit that may not answer the evidential question the court must decide.

The court evaluates the whole record and the parties’ procedural rights. Suppose a mother in Flacq has messages in which the alleged father discussed the pregnancy and paid maternity costs, but he later denies parentage. Those materials may explain why proceedings were brought; a controlled genetic test may address the biological issue more directly. Neither should be altered, selectively cropped or publicised online.

When an alleged father disputes paternity

Do not sign an acknowledgement merely to obtain access or settle an argument if paternity is genuinely disputed. Equally, silence in response to a letter is not scientific proof. Preserve relevant dates and communications, obtain the full birth entry, and respond through the proceeding so that any request for testing can be handled with safeguards.

A person already recorded as father may need advice on the distinct action and rules for challenging an existing legal status; recherche de paternité and désaveu de paternité are not interchangeable labels. The position also differs from adoption, which creates a legal parent-child relationship through its own statutory process rather than deciding biological paternity.

Paternity, maintenance and parental authority

Establishing filiation can provide the legal foundation for maintenance and parental responsibilities, but it does not set a monthly maintenance amount automatically. Financial relief requires the appropriate application and evidence of the child’s needs and the parents’ means. If an existing order is later ignored, use the enforcement process described in the maintenance-order guide.

Nor does recognition answer every question about where the child lives, schooling, medical decisions or contact. Those matters engage parental authority and any orders made for the child. Adults should avoid using a surname, birth-entry dispute or DNA appointment to pressure the child into choosing between parents.

Inheritance and civil-status consequences

Filiation can affect succession rights because Mauritian forced-heirship rules protect descendants. That is why an accurate birth entry and any judgement establishing parentage must be preserved. A family should not distribute an estate on the assumption that a child born outside marriage has no claim; the legal filiation and applicable succession rules need to be checked before assets are divided.

After a judicial decision or formal acknowledgement, confirm what certified documents the Civil Status Division needs to update or annotate its records. A court judgement, civil-status entry and ordinary photocopy serve different purposes. The separate overview of children born outside marriage addresses related rights without replacing the need to prove the particular child’s status.

Act promptly and protect the child

Parentage proceedings can be subject to technical conditions and time questions that depend on the action, claimant and facts. Do not rely on a generic internet deadline. Seek advice once the issue becomes real, especially where a birth is about to be registered, the alleged parent may leave Mauritius or an estate is being administered.

Keep the dispute private and child-focused. Do not publish accusations or genetic information, impersonate another person to obtain a sample, or involve a school in collecting evidence. Request the full birth entry rather than relying on a hospital bracelet or family account. The legitimate aim is a reliable legal determination and an accurate civil-status record, followed by any necessary child-support or parenting orders.

Frequently asked questions

Can paternity be established after the child is born?

Yes. Apart from joint registration at birth, the Civil Status Act provides for acknowledgement by deed, and disputed paternity may be determined through a judicial action. The correct route depends on the existing birth entry and whether the alleged father consents.

Will the court order a DNA test?

Genetic evidence may be sought in a contested case, but the court controls the proceeding and assesses admissible evidence. Obtain advice before arranging private testing so that identity, consent, sample integrity and laboratory evidence can be dealt with properly.

Does establishing paternity automatically grant custody?

No. Establishing filiation does not itself decide residence, contact or every exercise of parental authority, and it does not calculate maintenance. Those questions require the applicable agreement, statutory process or court order.
