Croatian citizenship can only be obtained through specific legal pathways defined in the Law on Croatian Citizenship (Zakon o hrvatskom državljanstvu). To apply, you must first qualify under one of the categories set out in the law. The official Croatian text of the law is available on the website of the Croatian Ministry of the Interior (MUP), along with English translations of specific provisions relevant to different citizenship pathways.
Each of the following sections covers a different pathway to Croatian citizenship, together with the legal provisions and eligibility criteria that apply.
Citizenship by origin: who qualifies at birth (Articles 4, 5 & 7)
The most straightforward route to citizenship applies to children with a direct Croatian family connection at birth. Under this basis, citizenship by origin is granted to:
- children whose parents were both Croatian citizens when the child was born,
- children born in Croatia to one parent who held Croatian citizenship,
- children who are foreign citizens or stateless persons and are adopted by Croatian citizens, in accordance with the Family Act (Obiteljski zakon),
- children born abroad to one Croatian-citizen parent, when the child would otherwise be left stateless,
- individuals born abroad to one Croatian-citizen parent may also qualify if they are registered before their 21st birthday with a Croatian embassy or consulate, or with a registry office in Croatia, for entry in the Croatian citizenship records (The Book of Citizens, Knjiga hrvatskih državljana),
- children born or found on Croatian soil whose parents cannot be identified or whose citizenship is unknown. This status can later be revoked if it is shown, before the person turns 14, that both parents hold foreign citizenship.
Article 4 of the law sets out that a child obtains citizenship by origin if both parents are Croatian citizens at the time of birth, if one parent is a Croatian citizen and the child is born in Croatia, or if the child is adopted by Croatian citizens under the relevant adoption law.
Article 5 addresses persons born abroad to one Croatian-citizen parent. If registered at a Croatian embassy, consulate, or registrar’s office (matični ured) before age 21, the child acquires citizenship by origin. For individuals born abroad to a Croatian-citizen parent who are over 21, MUP states that applications for entry in the Croatian citizenship records under Articles 4 and 5(3) are submitted to the Ministry of the Interior using the prescribed questionnaire for determining Croatian citizenship. Applicants living abroad submit their applications through the competent Croatian embassy or consulate.
If you were born before your parent acquired Croatian citizenship or if you do not qualify for citizenship by origin under Articles 4 or 5, you may have another route to Croatian citizenship through naturalization. Article 11 provides a special naturalization route for Croatian emigrants and their descendants, subject to the conditions set out in the Law on Croatian Citizenship.
Citizenship through naturalization: Croatian emigrants and their descendants (Article 11)
This is the route most often called Croatian citizenship by descent. It applies to Croatian emigrants and their children, grandchildren, and further descendants, along with the spouses of those descendants, under certain conditions.
Everything depends on whether your ancestor counts as an emigrant under Croatian law, and two situations rule out descendants most often:
- If your ancestor left Croatia and relocated to another republic within Yugoslavia or the former Yugoslavia, your descendants generally cannot claim citizenship on this basis.
- If your ancestor departed Croatia after October 8, 1991, your descendants are not eligible under this article.
Article 11 permits an emigrant and their descendants to acquire citizenship by naturalization without needing to meet the standard requirements found in Article 8, Paragraph 1, Points 2 through 4 (such as continuous residence, a foreign citizenship release, or the language test). A foreign spouse married to a person covered by Article 11(1) may likewise be exempt from those same requirements.
The law defines an emigrant as someone who left Croatian territory before October 8, 1991 with the intention of living abroad permanently. This also extends, as an exception, to members of the Croatian nation who emigrated from the territory of former states that once encompassed present-day Croatia. However, the definition excludes anyone who left under an international agreement, anyone who formally renounced Croatian citizenship, anyone who relocated to another republic that was part of the same state union as Croatia at the time, and anyone who left Croatian territory without ever having held former Croatian republican citizenship or domicile on the Croatian territory.
Standard naturalization requirements: residence, language, and more (Article 8)
Non-Croatian nationals with no prior Croatian family connection can still apply for citizenship through standard naturalization, provided they meet all of the following conditions:
- they are at least 18 years old,
- they have renounced their existing citizenship, or can show they will be released from it once granted Croatian citizenship,
- they have held continuous, registered permanent residence in Croatia for eight years,
- they have demonstrated knowledge of the Croatian language, Latin script, Croatian culture and the Croatian social system,
- their conduct suggests respect for the legal order and customs of Croatia, and there are no security concerns or obstacles tied to their application.
Minor children may also be granted citizenship on this basis in certain scenarios: when both parents acquire Croatian citizenship by naturalization, or when only one parent acquires Croatian citizenship by naturalization and the child lives in Croatia and has been granted permanent residence. Other provisions apply when only one parent acquires Croatian citizenship under Article 11 or Article 16 and the other parent is stateless or of unknown citizenship, including when the child resides abroad.
Article 8 lays out these same five legal requirements and clarifies a few practical points. An individual who is stateless, or who will automatically lose their existing citizenship upon naturalizing elsewhere, is treated as having satisfied the release requirement. If a person’s home country either refuses to grant a release or attaches conditions that cannot realistically be met, a signed declaration renouncing that citizenship (contingent on Croatian citizenship being granted) is accepted instead. The language and culture requirement is demonstrated through procedures prescribed by the competent authorities, and applicants over 60 are exempt from this requirement.
Article 8a adds that applicants who have not yet secured a release from their foreign citizenship, but meet every other condition under Article 8, may be issued a two-year guarantee of admission, giving them time to obtain the required release while the process is ongoing.
Citizenship for spouses of Croatian citizens (Articles 10 & 11)
Non-Croatian nationals married to a Croatian citizen and holding permanent residence in Croatia may apply under Article 10 without needing to satisfy the standard naturalization conditions in Article 8. The core requirements here are permanent residency and demonstrated respect for the legal order and customs of Croatia.
Two related scenarios extend this further:
- If a Croatian citizen living abroad applies for citizenship through descent, their spouse may also apply, either at the same time or afterward, without needing Croatian residence.
- If a Croatian citizen who was born in Croatia later emigrated before October 8, 1991 with the intention of permanently living abroad, their spouse may qualify under Article 11, again without a residence requirement.
Article 10 states that a foreigner married to a Croatian citizen, who has been granted permanent residence and lives in Croatia, can naturalize without meeting the first four points of Article 8, Paragraph 1. This same treatment extends to registered same-sex life partners of Croatian citizens, under the Law on Life Partnership of Persons of the Same Sex (Zakon o životnom partnerstvu osoba istog spola), and confirmed separately in Article 77 of that law.
Croatian citizenship based on special interest to Croatia (Article 12)
Individuals whose citizenship would serve Croatia’s interests, whether through professional skill, expertise, or another form of contribution, can be naturalized without meeting the usual age, residency, language, or renunciation conditions under Article 8.
A spouse of such an applicant may also become eligible, provided they have lived in Croatia with approved residence for at least one year.
Article 12 confirms that a foreigner whose admission would serve Croatia’s interest may naturalize without the first four conditions of Article 8, and extends the same exemption to their spouse under the residency condition noted above. MUP requests a reasoned opinion from the relevant ministry or state office to establish that this interest genuinely exists before the application proceeds.
Regaining Croatian citizenship: re-acquisition (Article 15)
A person who previously held Croatian citizenship and gave it up specifically to obtain a foreign citizenship required for their profession or activity in another country may apply to have Croatian citizenship reinstated.
To qualify, the applicant must demonstrate respect for the legal order and customs of Croatia and hold a valid residence permit in Croatia at the time of the application. Article 15 confirms this right of re-acquisition without requiring the applicant to meet the first four points of Article 8, so long as they hold an approved residence permit in Croatia.
Croatian citizenship for members of the Croatian people (Article 16)
People without Croatian citizenship who have, at some point, formally expressed an affiliation with the Croatian people, whether through legal transactions, references to such affiliation in certain public documents, the protection of the rights and promotion of the interests of the Croatian people, or active participation in Croatian cultural, scientific, or sports associations abroad, may apply on this basis. As with other paths, respect for the legal order and customs of Croatia is required.
Article 16 permits a member of the Croatian nation without Croatian residence to naturalize if they meet the fifth condition of Article 8 (the legal order and security requirement). Affiliation with the Croatian nation can be established through prior declarations in legal transactions, statements in public documents, advocacy on behalf of Croatian interests, or active involvement in Croatian associations abroad. If a person’s parents have already been confirmed as members of the Croatian nation, that person is not required to submit separate proof of their own affiliation.
International treaties and Croatian citizenship
The law also leaves room for citizenship matters to be settled through international treaties.
Which basis applies to you?
Every application rests on one of the legal grounds described above, and the right one is not always the obvious one. The best starting point is your family timeline: who held Croatian citizenship, when they left, and where they went. A specialist who focuses on Croatian citizenship can match that timeline to the correct article before you file.
