Joint child status for children born after divorce

Learn how Vietnamese law assesses parentage for a child born after divorce, including the 300-day presumption, birth registration and disputed parentage.

Definition of Joint Children of a Married Couple

Under marriage and family law, joint children of a married couple include:

Children born during a valid marriage.
Children born from pregnancy that occurred during a valid marriage.
Children born within a statutory period after termination of a marriage, including divorce, death of a spouse, or a judicial declaration of death.

The decisive factors include the time of birth, the time of pregnancy, and the date when the marital relationship legally ended.

Legal Provisions Regarding Children Born After Divorce

Clause 1 Article 88 of the Law on Marriage and Family 2014 provides:

“A child born within 300 days from the date of termination of a marriage is considered a child conceived during a valid marriage.”

However, when the father does not acknowledge the child, the father must submit documents and evidence to the court for verification. A judicial determination is then required. This mechanism ensures stability in parent–child relations and protects the welfare of the child by preventing disputes or attempts to avoid legal obligations.

Therefore, not every child born within 300 days from the date of divorce is automatically regarded as a joint child of the couple.

Exceptions to the Legal Presumption

Despite the statutory presumption, exceptions apply in the following circumstances:

(1) Evidence proves that the child has no biological relationship with the former husband: DNA test results confirming no biological connection; Mutual confirmation by both parties that the former husband is not the biological father of the child.

(2) Pregnancy occurs after the marital relationship has legally ended

When evidence shows that conception occurred after the date of divorce and had no connection to the former husband, the child is not regarded as a joint child.

(3) A request for parentage determination is submitted to the court

In cases of a dispute or a request for verification of parentage, the court assesses:

Scientific evidence, including DNA analysis and medical records.
Statements of the involved parties.
Dates of conception and birth.

The final judicial conclusion may differ from the statutory presumption.

Importance of Determining Joint Children After Divorce

Accurate classification of whether a child born after divorce is a joint child is crucial for the following reasons:

Protection of the right of child to comprehensive physical and mental development, as well as access to other legal benefits such as inheritance and insurance benefits.
Prevention and reduction of disputes after divorce.
Stabilization of family-related legal relationships.

Under current law, a child born within 300 days after a divorce is presumed to be a joint child of the married couple unless evidence or a court decision indicates otherwise. Understanding these rules enables parents to protect lawful rights and interests of the child and to avoid unnecessary disputes.
