Parents in a mixed Belarusian-foreign marriage often have several worries about their child’s citizenship: which citizenship the child actually holds, whether they can keep both, and — the fear that surfaces when a relationship ends — whether a divorce will take it away or replace it. Let’s start with the reassuring part: divorce by itself does not change a child’s citizenship. A child who is a Belarusian citizen remains one after the parents separate, a child who holds the foreign parent’s citizenship keeps it, and the divorce decree affects neither.
What divorce does change is who makes decisions about citizenship. Changing a child’s citizenship generally requires the consent of both parents — and, once the child is old enough, the child’s own — so a divorced parent cannot do it alone. A parent who, after the split, wants to renounce the child’s Belarusian citizenship or naturalise the child in another country needs the other parent’s agreement; without it, they face a dispute rather than a free hand. This article explains how a child acquires citizenship in the first place, whether they can hold two, and the point most often misunderstood: divorce leaves the child’s citizenship exactly as it was.
How a child of a mixed marriage acquires citizenship
Start with the basics. Belarus grants citizenship by descent under the Law on Citizenship: if both parents are Belarusian, the child is Belarusian wherever they are born; if one parent is Belarusian and the other is a foreign national, a child born in Belarus is a Belarusian citizen, while a child born abroad acquires Belarusian citizenship by the parents’ written agreement. Whatever the parents decide, the law ensures the child is not left stateless. So which citizenship a mixed-marriage child holds depends on the parents’ citizenship, the place of birth and, for a child born abroad, the parents’ choice. Establish this starting point first: everything about divorce and any later change follows from it.
How to confirm a child’s Belarusian citizenship
Knowing that a child is a Belarusian citizen by descent is one thing; having it on paper is another, and for a child born abroad it is worth doing early. The Belarusian citizenship of a child born outside the country is confirmed through the consular service or the citizenship authorities, based on documents proving the parents’ citizenship, the child’s birth and — for a child born abroad to one Belarusian and one foreign parent — the parents’ written agreement that the child will be a Belarusian citizen. The foreign birth certificate will generally need to be legalised or apostilled and translated before it can be used in Belarus. Once this is done, the child can be issued Belarusian documents, travel on them and be treated as the citizen they are. The practical lesson: do not leave the status to assumption. A child whose Belarusian citizenship is confirmed and documented is far easier to deal with — for a passport, for travel, for any later question — than one whose status everyone assumes but no one has formally established.
Can the child hold both citizenships?
This is the question mixed couples ask most often, and the answer is nuanced. Belarus does not formally recognise dual citizenship — within Belarus, a Belarusian citizen is treated solely as a Belarusian — but a child of a mixed marriage may in practice hold two citizenships, Belarusian and that of the foreign parent, because each country applies its own law. In practical terms, inside Belarus the child is treated as a Belarusian citizen, while abroad the foreign citizenship operates under that country’s law. So the situation is less “either/or” than parents fear and less “officially both” than they might hope: the child can in fact hold two passports, while each state treats the child as its own national.
Does divorce change the child’s citizenship?
Here is the reassuring answer, stated plainly: no. The parents’ divorce is not, in itself, a ground for a child to acquire, lose or change citizenship. The citizenship the child holds the day before the divorce is the one they hold the day after: the decree dissolves the marriage, not the child’s status. This is the single biggest fear for most parents in this situation, and it is unfounded. A Belarusian child of a mixed couple does not stop being Belarusian because the parents separate, and a child who holds the foreign parent’s citizenship does not lose it either. If you take away one thing from this article, let it be this.
The foreign side: two countries, two sets of rules
Belarus is only half the picture. The child’s other citizenship is governed entirely by another country’s law, and that country applies its own rules. The foreign parent’s country may grant citizenship by descent, by birth on its territory or on other grounds, quite independently of Belarus — which is why a child of a mixed marriage so often ends up with two. The two systems do not coordinate: each treats the child as its own national under its own law, so the child can hold both a Belarusian and a foreign passport, each used and recognised in its own country. For parents, this means two things. First, establish the child’s status on both sides, not just the Belarusian one, so that neither comes as a surprise later. Second, a change on one side does not automatically affect the other: renouncing a child’s Belarusian citizenship, for example, does not by itself affect the foreign citizenship, and vice versa. Two countries, two sets of rules, running in parallel. And because the foreign side is governed abroad, a Belarusian lawyer can only comment on it in general terms. Exactly how the other country treats the child — whether it grants citizenship, whether it allows dual nationality, what it takes to change it — is a question for a lawyer in that country, and it is worth asking alongside the Belarusian one so that both sides are understood together rather than one at a time.
What can change a child’s citizenship
Some things can change a child’s citizenship, but divorce is not one of them. One is a change in a parent’s own Belarusian citizenship, which can affect the child’s under conditions set by law — though, again, never in a way that leaves the child stateless. The other is a deliberate application by the parents to change the child’s citizenship — for example, to renounce the child’s Belarusian citizenship. This requires consent from both parents and, once the child reaches a certain age, from the child as well. The law also now requires that decisions on a child’s citizenship be made in the child’s best interests. So a change is a considered, consent-based step overseen by the citizenship authorities, not an automatic consequence of anything — least of all the end of the parents’ relationship.
Changing a child’s citizenship: consent and procedure
Because this is what divorced parents ask about most, it is worth explaining how a change actually works. Changing a child’s Belarusian citizenship — most commonly, renouncing it — is a formal procedure, not a simple form-filling exercise. The application goes through the citizenship authorities; it requires the consent of both parents and, once the child reaches a certain age, the child’s own written consent; and it is decided in the child’s best interests, with the law never allowing a child to be left stateless. Renunciation of Belarusian citizenship is decided at the highest level of the state, which shows that it is treated as a serious matter, not a routine one. So a change is neither quick nor unilateral: it requires the consents the law specifies, it is assessed against the child’s interests, and it can be refused. Parents who think they can quietly switch a child’s citizenship should understand that the procedure is designed precisely to prevent this. The design is deliberate and protective: because citizenship affects a child’s identity, travel, residence and rights, the law places the agreement of several people and the child’s own interests between an application and its outcome. That way, no single adult’s change of heart — during a divorce or afterwards — can rewrite the child’s status behind the other parent’s back.
How divorce complicates things
This is where the two threads come together. Because changing a child’s citizenship requires both parents’ consent, divorce does not change the citizenship, but it does change who controls any future change. After a separation, neither parent can alter the child’s citizenship unilaterally. A parent who wants to renounce the child’s Belarusian citizenship or naturalise the child abroad needs the other parent’s agreement, and if the parents disagree, the issue has to be resolved through negotiation or with the authorities, not by one parent’s decision. Note also that moving abroad after a divorce does not change the child’s citizenship either: a change in the child’s place of residence and a change of citizenship are different things. Where custody and these questions overlap, a Children’s Agreement recording what the parents have agreed can prevent a great deal of conflict later on.
When parents disagree after divorce
The consent requirement has an important consequence once parents have separated: if they disagree, a change generally cannot go ahead. Because both parents’ consent is required, a parent who objects can effectively block the change — the other parent cannot proceed alone, however strongly they feel or wherever they now live. This differs from many custody matters, where a court can decide between the parents; with citizenship, the required consents must be in place, and without them the change does not proceed. In practice, a divorced parent who wants to renounce the child’s Belarusian citizenship or naturalise the child in a new country has to persuade the other parent, not override them. This works both ways: it protects a Belarusian parent who fears the foreign parent will remove the child’s Belarusian citizenship, and a foreign parent who fears the reverse. The status quo stands unless both parents agree to change it — which, for most children, is the safer default. Where the disagreement is really about something else, such as where the child will live or travel, it is worth separating those issues from citizenship, because they have their own procedures: residence and travel can be decided or agreed on their own terms, without drawing the child’s citizenship into a dispute where it does not belong.
What to do
Two practical steps. First, establish and document the child’s citizenship clearly — especially for a child born abroad, whose Belarusian citizenship may need to be confirmed through the consular service. Keep the paperwork in order: a documented status is far easier to rely on than an assumed one. Second, if you genuinely want to change the child’s citizenship, obtain both parents’ consent (and the child’s, where required) rather than assuming one parent can act alone — and if the parents disagree, treat it as what the law makes it: a joint decision taken in the child’s best interests. For cross-border custody, relocation or citizenship issues during or after a divorce involving a foreign national, get legal advice: these issues interact in ways that are easy to misjudge from the perspective of just one country.
A worked example: a child born abroad, then a divorce
Here is how it all fits together. A Belarusian mother and a foreign father have a child born in the father’s country. By the parents’ written agreement, the child also becomes a Belarusian citizen, confirmed through the consulate, while holding the father’s citizenship under his country’s law. Years later, the parents divorce. The divorce does nothing to the child’s citizenship: the child remains both Belarusian and a citizen of the father’s country, exactly as before. Later, the father wants the child to give up Belarusian citizenship. He cannot do this alone: it requires the mother’s consent and, if the child is old enough, the child’s own, and the application would be assessed in the child’s best interests. Unless the mother agrees, the Belarusian citizenship stays. When the mother later moves with the child to a third country, neither citizenship is affected. The whole sequence — birth abroad, dual citizenship, divorce, relocation, a wish to change — leaves both of the child’s citizenships intact, because only a consented change made in the child’s best interests could alter them, and none took place. The lesson is simple but important: the events parents fear most — divorce, a move, one parent’s wish to change things — are exactly the ones that, on their own, do nothing to a child’s citizenship. The only thing that could change it is the one step that requires everyone’s agreement.
Common misconceptions
A handful of misconceptions cause needless worry, and each of them is wrong. That divorce removes or changes a child’s citizenship: it does not. That one parent can change it after the split: they cannot, without the other parent’s consent. That moving abroad changes it: it does not — residence and citizenship are separate matters. That dual citizenship is officially recognised: it is not, although a child may hold two in practice, with each country treating the child as its own. And that the parent with custody controls the child’s citizenship: they do not — custody and citizenship are different questions, and a change of citizenship requires both parents’ consent regardless of whom the child lives with. Most of these share one underlying confusion: treating citizenship as something that follows the parents’ relationship or the child’s address. It does not. It follows the law of each country the child belongs to, and it changes only through a deliberate, consented step taken in the child’s best interests — which is exactly why the fear of divorce that starts most of these conversations is unfounded.
At a glance: what does and doesn’t change a child’s citizenship
Divorce does not change it; only a deliberate step taken with the required consents can.
| Event | Does it change the child’s citizenship? |
|---|---|
| The parents divorce | No — divorce alone does not change a child’s citizenship |
| A parent loses or changes their Belarusian citizenship | It may affect the child’s citizenship under conditions set by law, but never so as to leave the child stateless |
| The parents apply to change the child’s citizenship | Yes, but only with both parents’ consent (and the child’s, once old enough) |
| The family relocates abroad after divorce | No — relocation does not change citizenship |
| The child reaches the age at which their consent is required | Any change now also requires the child’s own consent |

Frequently Asked Questions
Is our child a Belarusian citizen if one parent is a foreign national?
If the child is born in Belarus to one Belarusian and one foreign parent, yes — the child is a Belarusian citizen. If the child is born abroad, they acquire Belarusian citizenship by the parents’ written agreement, and the law ensures the child is not left stateless. So the citizenship of a child of a mixed marriage depends on the place of birth and, for a child born abroad, on the parents’ choice.
What if the child was born abroad?
A child born abroad to one Belarusian and one foreign parent acquires Belarusian citizenship by the parents’ written agreement, and this citizenship may need to be confirmed through the consular service. Without such an agreement, the child takes the foreign citizenship — unless that would leave the child stateless, in which case the child becomes a Belarusian citizen. Confirm and document the status rather than relying on assumptions.
Can the child have two citizenships?
In practice, often yes — Belarusian and the foreign parent’s — because each country applies its own law. However, Belarus does not formally recognise dual citizenship: inside Belarus the child is treated as a Belarusian citizen, while abroad the foreign citizenship operates under that country’s law. In short: two passports in practice, with each state treating the child as its own national.
Does divorce change the child’s citizenship?
No. The parents’ divorce is not a ground for a child to acquire, lose or change citizenship — the child’s citizenship is unaffected by the parents’ separation. This is the biggest fear for most parents here, and it is unfounded. What divorce changes is who can decide on any future change, not the citizenship itself.
Can one parent change it after divorce?
No — not alone. Changing a child’s citizenship generally requires the consent of both parents (and the child’s, once old enough), so after a divorce neither parent can do it unilaterally. A parent who wants to renounce the child’s Belarusian citizenship or naturalise the child abroad needs the other parent’s agreement; otherwise, the matter goes to the authorities.
Can a parent take the child’s Belarusian citizenship away?
Not unilaterally, and not through divorce. A child’s Belarusian citizenship can be changed only through an application backed by the required consents — both parents’ and, from a certain age, the child’s — decided in the child’s best interests and never leaving the child stateless. No single parent can take it away, and the parents’ separation does not affect it.
Does moving abroad change it?
No. Moving abroad, whether during the marriage or after a divorce, does not change a child’s citizenship: a change of residence and a change of citizenship are different things. The child keeps the citizenship they already hold, wherever the family lives.
How do I confirm a child’s Belarusian citizenship?
Through the relevant authorities — the citizenship and migration departments in Belarus, or the consular service for a child born or living abroad — by providing documents that prove the parents’ citizenship and the child’s birth. It is worth confirming and documenting the status rather than relying on assumptions, so that later steps (a passport, travel, a change of citizenship) are straightforward.
What about the child’s other citizenship?
That is governed by the other country’s law, which determines citizenship independently of Belarus — which is why a child of a mixed marriage often holds two. The two systems run in parallel: each treats the child as its own national, and a change on one side does not automatically affect the other. Establish the child’s status in both countries.
How is a child’s citizenship actually changed?
Through a formal application to the citizenship authorities, with the consent of both parents and, once the child is old enough, the child’s own. The decision is made in the child’s best interests and never leaves the child stateless. Renunciation of Belarusian citizenship is decided at the highest level of the state. The process is neither quick nor unilateral, and the application can be refused.
What if my ex-spouse and I disagree about the child’s citizenship?
Then a change generally cannot go ahead: because both parents’ consent is required, a parent who objects can block it, and the other cannot proceed alone. Unlike some custody matters, there is no court procedure to override a parent’s refusal on citizenship. So the status quo stands unless both parents agree, which protects each of them against a unilateral change by the other.
Does the parent with custody control the child’s citizenship?
No. Custody and citizenship are separate questions. Having custody does not give the parent the child lives with the right to change the child’s citizenship — that still requires both parents’ consent (and the child’s, once old enough). A custody arrangement determines where and with whom the child lives, not which citizenship the child holds.
Conclusion
For a mixed Belarusian-foreign family, a child’s citizenship is determined by descent and place of birth, may in practice be dual, and — the point that should ease the most common fear — is not changed by the parents’ divorce. What divorce does change is control over any future change, which becomes a joint decision taken in the child’s best interests. So establish and document your child’s citizenship, and if you ever want to change it, expect to need the other parent’s consent rather than having a free hand.
