Croatian Citizenship for Children: Can You Apply Together?

Can you apply for Croatian citizenship together with your children? In qualifying cases, yes. Croatian law provides routes through which minor children can acquire citizenship in connection with a parent’s naturalization, and an official application form exists for an adult and their child or children.

However, your own application does not automatically cover every member of the family. Each child’s legal route, age, documents and parental-consent requirements need to be addressed.

The first distinction is whether your child needs citizenship through a parent who was already Croatian at birth or naturalization connected with a parent’s citizenship application.

A Croatian citizenship lawyer can assess the family together while identifying the correct route for each person. That is more useful than completing the parent’s application first and assuming the children can be added later.

Which Citizenship Route Applies to Your Child?

Your child’s route depends on more than the existence of a Croatian ancestor. Parental citizenship at the time of birth, age, residence and the legal basis of the parent’s application can all matter.

The table below is a starting point for the assessment, not a final eligibility decision.

Preparing documents as a family does not mean every family member qualifies under the same provision.

Article 13: Croatian Citizenship for Minor Children

Article 13 of the Croatian Citizenship Act provides for a minor child to acquire citizenship through naturalization in four circumstances:

1. Both parents acquire Croatian citizenship through naturalization.
2. One parent acquires citizenship through naturalization, and the child lives in Croatia with approved permanent residence.
3. One parent acquires citizenship under Article 11(1) or Article 16.
4. One parent acquires citizenship through naturalization, the other parent is stateless or of unknown citizenship, and the child lives abroad.

For the third category, Article 13 does not impose the Croatian permanent-residence condition found in the second category. This is an important distinction for qualifying diaspora families living abroad.

Why the Parent’s Exact Article Matters

The provision specifically refers to Article 11, paragraph 1, and Article 16. Do not assume that every application described as “citizenship through ancestry” or “citizenship through marriage” creates the same position for children.

The family review should identify the parent’s actual legal basis before deciding how the children should be included.

For the broader ancestry route, read our Croatian citizenship by descent guide.

Joint Applications Still Need Child-Specific Evidence

The official application forms allow an adult to apply with a child or children. However, the child’s documentation and the relevant consent or legal authority still need to be addressed.

Simply naming a child in the adult applicant’s family-information section should not be assumed to constitute an application for that child’s citizenship.

Was a Parent Already Croatian at Birth?

If you held Croatian citizenship when your child was born, first assess citizenship by origin rather than automatically preparing a naturalization application.

Article 4 covers, among other circumstances, a child born to two Croatian citizen parents and a child born in Croatia to one Croatian citizen parent.

Article 5 addresses a person born abroad to one Croatian citizen parent and generally requires registration to be requested before the person’s 21st birthday.

The decisive question is when the parent legally held citizenship—not simply when a recent passport or citizenship certificate was issued.

Birth Before and After a Parent’s Naturalization

Illustrative example, not a client case: a parent became Croatian through naturalization in 2022. One child was born in 2018 and another in 2024.

The younger child’s case starts with the question of citizenship through a parent who was already Croatian at birth. The older child’s case cannot be treated identically merely because the parent later naturalized.

A decision confirming that the parent already held Croatian citizenship under earlier law may establish a different history. Read what the decision actually determines.

For the legal distinctions, see Croatian citizenship through parents, emigrants and Croatian affiliation.

Under 18 and Under 21 Are Different Rules

Article 13 concerns minor children. Article 5 can also be relevant to certain adults under 21. These are different age rules attached to different legal routes.

A 19-year-old whose parent was Croatian at the time of birth may need an Article 5 assessment. A 19-year-old whose parent is only now applying through a historical emigrant ancestor needs a different analysis.

Adult children should have their own eligibility assessed rather than being treated as dependants automatically covered by a parent’s minor-child application.

What if Your Child Is Close to Turning 18?

Raise the child’s age before finalizing the application strategy, particularly if the parent’s application is already pending.

Do not assume that booking an appointment or submitting only the parent’s application preserves the child’s eligibility as a minor.

If a child may reach adulthood during processing, obtain individual advice about the pending application and any further steps required. Avoid assuming either that age is automatically “locked in” or that a new application will always be necessary.

Does the Other Parent Need to Consent?

For a minor child’s naturalization under Article 13, one parent generally submits the application with the other parent’s written consent, or the child’s guardian submits it. The law provides specific exceptions.

The other parent’s consent is different from the other parent applying for Croatian citizenship. A non-applying parent may still need to consent to the child’s application.

Divorce Does Not Automatically Remove Consent

Divorce or the fact that a child mainly lives with one parent does not, by itself, establish that the other parent’s consent can be omitted.

Review any court order carefully, particularly who is authorized to decide the child’s status. Article 13 includes exceptions involving a deceased parent and specified circumstances concerning legal capacity or parental responsibility.

Where the other parent’s whereabouts are unknown, the specified exception requires prior approval from the competent social welfare authority. An unsupported statement that the parent cannot be contacted is not a substitute.

Confirm How Consent Must Be Given

MUP explains that consent may also be given in the designated section of Form 2 or Form 3 when the application is submitted.

Confirm the applicable signing and certification arrangements with the receiving authority before the appointment, especially if the parents live in different countries.

Documents for Your Child’s Citizenship Application

Official guidance for applications including minor children identifies the child’s birth record, evidence of citizenship status and the other parent’s written consent unless an exception applies. Check the relevant identity-document requirements as well.

The government guidance does not require a birth extract where the child’s birth is already entered in the Croatian Registry of Births.

For practical preparation, separate the family file into:

• The child’s records: birth, citizenship and identity documents required for the route.
• Parental records: evidence of parentage and the relevant citizenship status or application.
• Consent or authority: parental consent, guardianship documentation or evidence supporting a statutory exception.
• Connecting records: marriage, name-change or other documents explaining differences between the records.
• Route-specific evidence: ancestry, emigration or other material supporting the qualifying case.

This is a preparation framework, not a universal official checklist. Confirm the final requirements for your procedure before ordering documents.

Check Parents’ Names Across the Records

Compare the parent’s name on the child’s birth certificate with the parent’s passport, birth certificate and marriage records.

A married surname on a passport may differ from the name used when the child was born. Identify the record that explains the connection before treating the family file as complete.

Read our guide to name, surname and date discrepancies in Croatian citizenship documents.

Adoption, guardianship, stepfamilies or disputed parentage require individual review of the legal parent-child relationship. Sharing a surname or living together should not be treated as sufficient proof.

Apostille and Croatian Translation

Not every foreign document needs an apostille. The authentication requirements depend on the issuing country, the document and applicable international agreements.

Review the final record before arranging the legalization and certified Croatian translation required for its use.

If a record contains an error that needs correction, translating it first can mean paying for the same work again.

Where Do Parents and Children Apply?

For naturalization, applicants without approved temporary or permanent stay in Croatia generally apply through the competent Croatian diplomatic mission or consular office abroad. Applicants with the relevant Croatian residence status generally submit through the competent police administration or station.

MUP conducts the naturalization procedure.

Before booking, confirm which office is competent for your address, which parent must attend, how consent will be provided and whether the child needs to attend.

Do not assume that naturalization and registration appointments have identical requirements.

Preparing as a family does not necessarily mean one appointment or one identical procedure for everyone.

Already Applied Without Including Your Children?

Start by obtaining a copy of the application that was submitted.

Check whether citizenship was actually requested for your children or whether they were only mentioned in the family-information section.

The next assessment should establish your legal basis, whether the application is pending or decided, each child’s age and registration status, and which documents or consents were submitted.

MUP provides adult-and-children and children-only application forms. However, their existence does not determine which procedure is appropriate for your particular family.

Do not assume that emailing a birth certificate automatically adds a child to a pending case. Confirm whether a supplement or a separate application is required.

If the authority has already asked for further evidence, read how to respond to an MUP additional-document request.

Does Applying Together Save Time or Money?

A coordinated plan can avoid researching the same Croatian ancestor independently for each family member. It also makes it easier to maintain consistent explanations across the family documents.

However, do not assume that one set of originals, one translation or one fee covers every applicant.

Before ordering records, confirm the copies required for each procedure and request a written breakdown of professional fees and third-party costs.

There is no guaranteed family processing time. MUP states that duration depends on the complexity of the individual request and the facts that need to be established.

For planning, use our Croatian citizenship processing time guide. Keep document preparation and appointment availability separate from the authority’s decision-making time.

How a Croatian Citizenship Lawyer Helps Your Family

A family review should do more than confirm that one parent has Croatian ancestry. It should identify the proposed route, documents and preparation steps for every person seeking citizenship.

Through Croatian Immigration Lawyer, family applications can be coordinated with licensed Croatian attorneys for legal advice and representation. The engagement should clearly identify who performs each task.

Common Family Application Mistakes

Assuming Your Approval Covers Every Child

Confirm the procedure and application for each child. Do not substitute a family relationship for the relevant legal requirements.

Treating All Siblings the Same

Different ages and birth dates relative to a parent’s acquisition of citizenship can create different legal questions.

Confusing Under 18 With Under 21

The minor-child naturalization route and registration through a parent who was Croatian at birth are not interchangeable.

Leaving Parental Consent Until the Appointment

Identify consent or parental-responsibility issues before the remaining documents are finalized and translated.

Planning the Children’s Cases Only After Filing

Even when separate procedures are needed, assess the family together at the beginning. That gives you a clearer plan than revisiting every document after the parent’s application has already been submitted.

This article provides general information and does not constitute legal advice for an individual family. Eligibility depends on the child’s age, birth circumstances, parental citizenship history, applicable law, parental responsibility and available records. Families with an approaching age threshold, a pending application or a consent issue should obtain individual advice before filing.
