Missing a marriage certificate in Vietnam? Learn how civil-status extracts, replacement records and proof of marriage may help prepare a divorce filing.
Why Is the Marriage Certificate Important?
Under the Law on Marriage and Family 2014, a marriage is legally valid only when it is registered at a competent civil status office in accordance with the law. This means that only couples with a marriage certificate are recognized by law as husband and wife. Without this legal document, your union is not considered a lawful marriage - no matter how long you’ve lived together or how many children you share.
Can You File for Divorce Without a Marriage Certificate?
No, you cannot get a legal divorce if your marriage was not legally registered.
Instead of a divorce procedure, your case will be handled as a request to terminate an illegal cohabitation or resolve rights and obligations arising from a man-woman relationship without legal marriage. The court will not declare a divorce, but it may still resolve related issues such as:
- Child custody and child support
- Division of jointly acquired property
- Compensation for contributions, if applicable

This type of case is not governed under divorce procedures, but it is still a civil matter that can be brought before the court.
What Happens to Children and Property?
Even without a marriage certificate, the law ensures protection for children and property:
- Children: According to Article 15 of the Law on Marriage and Family 2014, children born from an unregistered marriage still enjoy full legal rights regarding paternity, care, and support.
- Property: If the couple can prove joint contributions (even without a legal marriage), the court may consider dividing the assets in a fair and reasonable way under civil law principles.
What Is a Unilateral Divorce and Can It Apply?
A unilateral divorce occurs when one party files for divorce without the consent of the other. However, this only applies to legally recognized marriages. If there is no valid marriage registration, you cannot initiate a unilateral divorce.
Still, the concept of what is a unilateral divorce is important to understand for those who are legally married but facing serious marital breakdowns. In such cases, the applicant can file for divorce unilaterally, especially if the other party is abusive, uncooperative, or missing.
Recommended Legal Actions If You Don’t Have a Marriage Certificate

If you are not legally married but want to separate, here are the steps you can take:
- File a petition to the court to resolve issues regarding children and property under civil proceedings.
- Provide documents or witnesses that prove cohabitation, shared finances, or joint parenting.
- Seek legal advice to determine whether marriage registration is possible (retroactive registration) before separation, if needed.
