Annulment of Marriage in Vietnam
Not every marriage that ends is ended by divorce. Some marriages, in the eyes of the law, should never have been valid in the first place, and for those the remedy is not divorce but annulment. An annulment does not dissolve a marriage so much as declare that, legally, it was never a proper marriage at all.
In Vietnam this is framed as the annulment of an illegal marriage, an illegal marriage being one entered into in breach of the conditions the law sets for marrying. Understanding when a marriage can be annulled, who can ask for it, and how it differs from divorce matters to anyone who suspects their marriage, or someone else’s, was never lawful to begin with.
Annulment and Divorce Are Not the Same Thing
The two are easy to confuse, because both bring a marriage to an end, but they rest on opposite premises.
A divorce accepts that a valid marriage existed and ends it going forward. Both parties acknowledge they were properly married; the marriage simply is not to continue. An annulment says something quite different: that the marriage was flawed from the outset, that a legal requirement for a valid marriage was never met, and that the law should therefore treat the marriage as never having validly existed. This is why annulment is described as making a marriage invalid rather than dissolving it.
The distinction is not merely technical. It shapes who can bring the case, what the grounds are, and how the law treats the parties afterward. If your situation is really one of a valid marriage that has broken down, the route is divorce. If it is one of a marriage that was never lawful, annulment is the relevant path.
What Are the Grounds for Annulment in Vietnam?
A marriage is treated as illegal, and so open to annulment, where it was entered into in violation of the legal conditions for marrying. Those conditions, and the prohibitions that go with them, are the heart of the matter.
The common grounds include marrying under the legal age, which is twenty for men and eighteen for women. They include a lack of genuine voluntary consent, where one party was forced, coerced, or deceived into the marriage. They include bigamy, where a person who is already married marries someone else while the first marriage still stands. And they include marriage between close relatives, meaning those of direct blood line or within three generations, which the law prohibits.
There is a further category worth naming, because it arises often in a cross-border context: the sham marriage. A marriage entered into not to build a family but to obtain immigration status, residence, naturalisation, or some other benefit is not a genuine marriage in the eyes of Vietnamese law, and it too can be annulled, even where the formal conditions of consent and capacity appear to have been met. What is missing there is the real purpose of marriage itself.
These grounds connect directly to the conditions for a valid marriage in Vietnam. Where one of those conditions was breached at the time of the marriage, the marriage is vulnerable to annulment.
Who Can Request an Annulment
The law does not leave this only to the couple. Depending on the ground, several people and bodies may ask a court to annul an illegal marriage.
A person who was forced or deceived into the marriage can request annulment themselves, or ask a competent person or organisation to do so on their behalf. Where the ground is bigamy, the existing spouse of the person who married again can bring the request, as can a parent, child, guardian, or other legal representative of a person married unlawfully. Beyond the family, certain authorities and organisations, including the Procuracy and bodies such as the Women’s Union, have standing to request annulment or to be asked to do so when an illegal marriage comes to light.
This wider circle of people who can act reflects that some illegal marriages, a forced marriage, or a bigamous one, harm interests beyond those of the two people who went through the ceremony.
When an Illegal Marriage Can Still Be Recognised
Vietnamese law includes a sensible and often overlooked provision here. An illegal marriage is not always doomed to annulment; in some cases it can be saved.
Where, by the time the court comes to deal with the request, both partners now fully satisfy the conditions for a lawful marriage, and both ask the court to recognise their marriage, the court can recognise the marriage relationship rather than annul it. A common example is a couple who married below the legal age and have since both reached it. If they satisfy every other condition and wish to stay married, the court need not undo the marriage.
One detail matters in that situation. Where the court recognises the marriage in this way, the marriage is treated as valid from the time the conditions were actually met, not backdated to the original ceremony. The period before that point is not retrospectively legitimised, which can affect questions of property and timing, so it is worth understanding rather than assuming the recognition simply erases the problem.
What Happens to Children and Property After an Annulment
Because an annulment treats the marriage as never having been valid, people often fear it leaves children and property in limbo. Vietnamese law addresses both, and the position is more reassuring than the label suggests.
Children are protected. The rights and obligations between parents and children after an annulment are settled in the same way as they are on divorce, which means questions of custody, care, and child support are resolved on the same principles, with the child’s interests at the centre. A child’s position does not depend on whether the parents’ marriage was valid.
Property is divided on its own set of principles. As a general rule each party keeps their own personal property, while property treated as common is divided according to the contribution each made, and the law takes particular care to protect the lawful interests of a person who was deceived or forced into the marriage. The couple are also required to stop living together as a married couple once the marriage is annulled.
Which Court Handles an Annulment
A request to annul an illegal marriage is a matter for the court, and following the reorganisation of Vietnam’s court system in 2025, a first-instance family matter of this kind is handled by the regional-level People’s Court with jurisdiction over the area, which replaced the former district-level courts. Where the marriage has a foreign element, one party a foreign national, or a party living abroad, the case is dealt with at the level that handles foreign-element matters. Older guidance that refers a request to the district-level People’s Court reflects the previous structure and is now out of date.
How Long Does an Annulment Take?
As a rough guide, a straightforward annulment that nobody contests is usually resolved in around two to four months from the point the court accepts the case. A contested one, where the other party disputes it or the facts have to be proven through evidence, more commonly runs to six months or more. Where there is a foreign element, a party living abroad, or documents that must be legalised and translated overseas, it can take a year or longer, because the court often has to seek assistance across borders.
These are not fixed by statute. An annulment is handled as a civil case, so it follows the same rhythm as other family matters: the court checks the file within one to two weeks, accepts the case, verifies the facts, and then decides. What moves a case toward the shorter end is a clear, documented ground, a prior marriage certificate in a bigamy case, or a birth record in an under-age one, with neither side contesting it. What pushes it toward the longer end is dispute, evidence that takes time to assemble, or a party and paperwork spread across two countries.
So the honest short answer is months rather than weeks for a simple case, and potentially a year or more for a complex or cross-border one. Which end a particular situation falls toward is usually clear once the ground and the circumstances are known.
Where This Leaves You
Whether a marriage can be annulled turns on the specific facts: what condition was breached, when, by whom, and whether the situation has since changed. Two situations that sound alike can lead to very different outcomes, an annulment in one case, a recognised marriage or a divorce in another. Working out which one you are actually in is the important first step, and it is not always obvious from the outside.
