Enforcing a Foreign Custody Order in Vietnam

A custody order made by a court in another country does not take effect in Vietnam on its own. If the child is living here and the other parent will not follow the order, the parent who holds it has to ask a Vietnamese court to recognise and enforce it. Until a court does so, the order has no legal force here.

The process is well defined, and it does not involve arguing the whole custody case again. But it has firm conditions and a time limit, and in many cases the outcome depends on what has already happened in Vietnam by the time the application is made. This guide explains how recognition works for a custody order, the grounds on which it can be refused, how a recognised order is enforced, and when a fresh custody case in Vietnam is the better route.

Does a Foreign Custody Order Have Legal Force in Vietnam?

Not automatically, although Vietnamese law does recognise some foreign family judgments without any court process. Under Article 431 of the Civil Procedure Code, a foreign marriage or family judgment is recognised automatically where nothing in it needs to be enforced in Vietnam and no one objects. The typical example is a divorce that simply ended the marriage. As we explain in our guide to the recognition of a foreign divorce, that kind of judgment can often just be recorded in the civil status register.

A custody order is different because it decides something about a child and usually needs to be carried out. It says where the child lives and with whom, and it may require one parent to hand the child over. Where that is in dispute, or where the order has to be enforced against a parent in Vietnam, the holder of the order needs a court decision recognising it and permitting its enforcement here.

How a Vietnamese Court Recognises a Foreign Custody Order

The first question is whether Vietnam will consider the order at all. A foreign judgment is considered for recognition where Vietnam has a treaty with the country concerned that covers it, or on the basis of reciprocity where there is no such treaty. Vietnam has mutual legal assistance treaties covering family judgments with only a limited number of countries, so for many parents the application rests on reciprocity.

Since the reorganisation of Vietnam’s courts on 1 July 2025, an application of this kind is heard at first instance by the regional People’s Court, usually the one for the area where the parent who is required to comply lives. The application can be filed directly with the court, or through the Ministry of Justice where a treaty requires that route. The court’s decision can be appealed, and an appeal goes to the provincial-level People’s Court.

The application is made by the person entitled under the order. That is usually the parent awarded custody, but it can equally be a parent whose foreign order gives them visitation or contact rights. A parent who is being kept from seeing their child in Vietnam can use the same process to give those rights legal effect here.

The court’s role at this stage is narrower than many parents expect. Under Article 438 of the Civil Procedure Code, the court considering the application does not re-try the custody case. It does not ask afresh which parent should raise the child. Instead it checks the foreign order and its supporting documents against the conditions the law sets, and then decides whether to recognise it. If the order is recognised, it can be enforced in Vietnam in the same way as a decision of a Vietnamese court.

Grounds on Which Recognition Can Be Refused

Because the court is checking conditions rather than re-hearing the case, the grounds for refusal decide most contested applications. Article 439 of the Civil Procedure Code sets them out. The ones that matter most for custody orders are these:

A Vietnamese court has already decided the same matter in a judgment that has taken legal effect, or had accepted the case before the foreign court accepted it.
The parent in Vietnam was not properly notified of the foreign proceedings, or did not receive the papers in time to take part, where the order was made in their absence.
The order is not yet legally effective in the country that made it, or it has been annulled or suspended there.
The time allowed for enforcement has run out, under the law of the country that made the order or under Vietnamese law.
Recognition would conflict with the basic principles of Vietnamese law. In family matters, the protection of the child’s interests is one of those principles.

The remaining grounds cover cases where the foreign court lacked jurisdiction under Vietnamese rules, and cases where the order fails a condition in a treaty that applies.

Why Timing Decides Many Cross-Border Custody Cases

Two timing rules matter most in these cases. The first is the deadline. An application for recognition must be made within three years of the date the foreign order took legal effect. Time lost to a genuine event beyond the applicant’s control is not counted, but that has to be proved. If a parent waits too long, this route is closed.

The second is the overlap with Vietnamese proceedings, which is easiest to see through a common scenario. A court abroad gives a mother custody, and the father later brings the child to Vietnam and keeps them here. The mother applies to have the order recognised. In the meantime, the father files his own custody case with the local court in Vietnam. If his case reaches a final judgment first, the mother’s application can be refused, because Vietnam now has its own decision on the same question. Her foreign order then cannot be enforced here, and the question of the child’s care is settled by the Vietnamese judgment instead.

This is why the order of steps matters so much in a cross-border custody case. The parent holding the foreign order is usually best served by applying promptly, with complete documents, rather than waiting to see whether the other parent will cooperate. The parent in Vietnam, for their part, should understand that filing a local case does not override the foreign order automatically, because the outcome depends on what the Vietnamese court decides and when.

What Happens if Circumstances Have Changed

Custody orders are often recognised some time after they were made, and by then the child may be older and settled in a new home and school. Since the court does not re-try the case at the recognition stage, a parent cannot use that stage to argue that the arrangement no longer suits the child.

That does not leave a parent without a remedy. Once an order has effect in Vietnam, either parent can ask a Vietnamese court to change custody where the child’s circumstances have materially changed, under the ordinary rules on changing a custody arrangement. In that case the court looks at the child’s welfare as it stands now, and it must take into account the wishes of a child aged seven or older.

When a New Custody Case in Vietnam Is the Better Route

Recognition is not always available or sensible. The three-year deadline may have passed. The country that made the order may have no treaty with Vietnam and no practice of reciprocity that a court will accept. Or a Vietnamese court may already be dealing with the child’s custody.

In those situations, the more practical step is often to ask a Vietnamese court to decide custody directly. Vietnamese courts can hear a custody case with a foreign element where the child or the other parent lives in Vietnam, and they decide it on the best interests of the child. The foreign order is not binding in that case, but the order and the history behind it can be put before the court, which can take them into account in understanding how the child came to be in Vietnam. Our guide to the custody rights of a foreign parent explains how Vietnamese courts approach these cases.

A case in Vietnam also opens up interim protection. Where the child’s immediate care is in question, a parent can ask the court for an emergency temporary measure under Article 114 of the Civil Procedure Code, such as placing the child in the care of a particular person until the case is decided. In an urgent situation, that request can be made at the same time as the case is filed. And if the parents reach agreement at any stage, the court can record their agreement in a decision, which is usually much faster than a contested hearing.

How a Recognised Custody Order Is Enforced in Vietnam

Once recognised, the order is carried out by the civil judgment enforcement authorities under the Law on Civil Judgment Enforcement No. 106/2025/QH15, which came into force on 1 July 2026. For a custody order, enforcement usually means requiring the parent who is keeping the child to hand the child over to the parent named in the order.

Handing over a child is the most delicate kind of enforcement. The authorities generally start by seeking voluntary compliance, and coercive measures against the parent keeping the child are available where that fails. Because a child is involved, these steps tend to move more slowly and carefully than the enforcement of a money judgment. Parents should plan for that, and should be prepared to support the handover in a way that protects the child.

Recognition matters all the more because Vietnam is not a party to the 1980 Hague Convention on international child abduction, so there is no treaty mechanism that orders a child’s prompt return from Vietnam. In most cases, recognition and enforcement of a custody order, or a fresh custody case in Vietnam, is the legal route available.

Preparing the Documents for Recognition

An application needs a complete set of documents. The core items are:

A certified copy of the foreign custody order.
Confirmation that the order is legally effective and has not expired for enforcement, unless the order itself says so.
Proof that the other parent was properly notified, where the order was made in their absence.
A Vietnamese translation of each document.

The way foreign documents are authenticated has also changed recently. Since 11 September 2026, Vietnam has applied the Apostille Convention. Court documents from another member country now need only an apostille, instead of consular legalisation. The exceptions are countries that objected to Vietnam’s accession, currently Austria, Czechia and Germany, and countries outside the Convention, where consular legalisation still applies. An apostille does not replace the need for a certified translation.

Making a Foreign Custody Order Work in Vietnam

A foreign custody order can be given full effect in Vietnam. What decides the outcome is preparation and timing: confirming early that recognition is available for the country concerned, filing within the deadline, and having documents that meet the conditions in Article 439.
