Tunisian citizenship by marriage, through a Tunisian mother or by naturalisation: conditions, where to apply, dual citizenship and nationality certificate.

You can be Tunisian from birth, through a Tunisian father or a Tunisian mother, or acquire Tunisian nationality later, mainly by naturalisation. A foreign spouse of a Tunisian benefits from easier conditions than other foreigners, but it is not automatic and depends on the Tunisian Nationality Code in force when the application is made. A Tunisian does not lose Tunisian nationality automatically by acquiring another one: loss can only be pronounced by decree (Article 30 of the Code). Who is Tunisian by birth? The main text is the Tunisian Nationality Code. Its core rule today is simple: under Article 6, as rewritten by Law 2010-55, a child born to a Tunisian father or a Tunisian mother is Tunisian. The rules for children of a Tunisian mother and a foreign father used to be stricter. The new rule covers anyone who was still a minor when it came into force (Article 3); people born abroad to a Tunisian mother and a foreign father who were already adults could claim Tunisian nationality by declaration within one year of the 2010 law coming into force, and that window has now closed. If that is your situation, have a lawyer look at your case. The Code also grants Tunisian nationality in some narrower situations linked to birth in Tunisia (Articles 7 to 10), for example a child born in Tunisia to unknown parents. In practice, being Tunisian by birth does not depend on having papers, but papers are what prove it. For a child born abroad, the usual steps are: have the birth transcribed in the Tunisian civil register through the Tunisian consulate where you live; obtain a Tunisian birth certificate once the transcription is done; apply for Tunisian identity documents, such as a passport or national identity card, depending on age and the current conditions; where needed, ask for a nationality certificate for certain official files. The longer the transcription is put off, the more documents you are likely to be asked for later, so don't delay it. Tunisian citizenship by marriage: can a foreign spouse become Tunisian? Marrying a Tunisian does not make the foreign spouse Tunisian automatically. It opens an easier route, and the Code treats foreign wives and foreign husbands differently: A foreign wife of a Tunisian man can claim Tunisian nationality by declaration once the couple has lived in Tunisia for at least two years (Article 14); the President of the Republic can oppose this by decree within a set period (Article 15). If her own country's law takes away her original nationality when she marries a foreigner, she becomes Tunisian at the time of the marriage (Article 13); A foreign husband of a Tunisian woman can apply for naturalisation without the usual residence period, provided the couple lives in Tunisia when the application is filed (Article 21); naturalisation remains discretionary. A marriage only counts for nationality purposes if it was celebrated in a form recognised by Tunisian law or by the law of the country where it took place (Article 29). In practice, have a marriage concluded abroad transcribed at the consulate or in the Tunisian civil register so that you can prove it in your file. How to apply for Tunisian nationality by naturalisation Outside marriage, a foreigner may apply for naturalisation. It is granted by decree (Article 19) and is not a right: the President of the Republic decides whether to grant or refuse it and does not have to give reasons (Article 45), so even a complete file can be refused. The Code sets these conditions: habitual residence in Tunisia for the five years before the application, with some exceptions (Articles 20 and 21), and that residence must be lawful (Article 28); being an adult; sufficient knowledge of Arabic, judged according to the applicant's circumstances; being of sound mind and, given one's physical health, not being a burden or a danger to the community; good character, and no prison sentence of more than one year for an ordinary offence unless wiped out by rehabilitation (Article 23). The application is filed with the Ministry of Justice, or sent to it by registered letter, with all supporting documents, in particular civil-status records (Articles 39 and 42); the Ministry then has an inquiry carried out. Expect to have to prove each condition, such as residence and a clean criminal record. Foreign documents generally need an apostille or legalisation and an Arabic translation. Ask the Ministry for the current list before collecting anything. Something to watch: a private member's bill amending the Nationality Code (proposition de loi n° 17/2026) was filed with the Assembly of the Representatives of the People in early 2026. It would tighten naturalisation, in particular by requiring lawful entry into Tunisia and seven consecutive years of habitual residence. It was still before the rights and freedoms committee when this guide was written. Check whether the Code has been amended before you apply. Does Tunisia allow dual citizenship? Yes, in practice. Tunisian law does not take Tunisian nationality away just because a Tunisian acquires another one: when a Tunisian voluntarily acquires a foreign nationality, loss of Tunisian nationality can only be pronounced by decree (Article 30). Many Tunisians abroad therefore hold two nationalities. Keep two points in mind: the Code provides for one specific case of loss: a Tunisian who holds a post in a foreign State's public service or in a foreign army and keeps it after being ordered to resign (Article 32); whether the other country accepts dual nationality is a matter for that country's law. A foreigner who becomes Tunisian may lose their original nationality if their own country's law says so. Nationality certificate, loss and renunciation A nationality certificate proves that a person is Tunisian, unless the contrary is proved (Article 64). It is issued by the Minister of Justice and, where the nationality is by birth, by the cantonal judge (juge cantonal) where the applicant lives or by Tunisian diplomatic and consular officers abroad (Article 63). Since 2023, according to the Ministry of Justice, it can be obtained on the spot at any cantonal court through an electronic system. It is often required in official files, for certain jobs or for some procedures abroad. Tunisian nationality can only be lost in the cases and under the procedures set out in the Code, by decree. Someone who acquired Tunisian nationality can also be deprived of it by decree in serious cases set out in the law, such as a conviction for an offence against State security (Article 33), and a naturalisation can be withdrawn if its conditions were not met or it was obtained by fraud (Articles 36 and 37). These rare, technical situations call for a lawyer. Frequently asked questions My mother is Tunisian and my father is not. Am I Tunisian? Under the current rule, the child of a Tunisian mother is Tunisian. If you were already an adult when the 2010 law came into force, your situation needs looking at: start by having your birth transcribed at the consulate and see a lawyer. How long must a foreign spouse wait before applying? Under the current text of the Code, a foreign wife of a Tunisian man can make her declaration once the couple has lived in Tunisia for at least two years; a foreign husband of a Tunisian woman needs no minimum residence period, as long as the couple lives in Tunisia when he applies. Check for any reform before you file. Will I lose my other nationality if I become Tunisian? That depends on the law of your other country, not on Tunisian law. Check with that country's authorities for your own situation. Is naturalisation guaranteed if my file is complete? No. Naturalisation is granted by decree; the President of the Republic decides whether to grant or refuse it, without giving reasons, even when the conditions are met. When should you see a lawyer? A lawyer can help you check whether you are already Tunisian (often the case for children of Tunisian mothers born abroad), choose the right route for a foreign spouse, prepare a complete naturalisation file, or deal with a refused transcription, a disputed nationality or a loss of nationality. These files often involve documents from two countries, so choose a lawyer used to cross-border family and civil-status matters. The site's directory lists lawyers registered with the ONAT by city.
