Polish citizenship by descent: requirements and how to apply

Polish citizenship by descent means that you are already a Polish citizen because a parent, grandparent or great-grandparent was one and passed it on. Polish law sets no limit on the number of generations; what matters is that citizenship passed from parent to child at every step and that nobody in the chain lost it before the next generation was born. If the chain holds, you do not apply for a new citizenship. You ask a Polish voivode to confirm the citizenship you already have, and you keep your current passport.

This article explains how that works for families in the United States, Israel, the United Kingdom and Canada: which rules decided whether citizenship passed to a child, what could break the chain, and how the confirmation procedure runs from filing to decision.

Can I get Polish citizenship by descent?

You can if two things are true. First, at least one ancestor in your direct line held Polish citizenship. Second, that citizenship passed to each following generation down to you and was not lost along the way.

Poland has had four citizenship acts: of 20 January 1920, 8 January 1951, 15 February 1962 and 2 April 2009. The 2009 act, in force today, provides in Article 2 that everyone who held Polish citizenship under the earlier laws remains a Polish citizen. Each event in a family’s history (a birth, a marriage, an emigration, a foreign naturalization) is assessed under the act that was in force when it happened. A great-grandfather born in 1910, a grandmother born in 1935 and a father born in 1960 are therefore checked under different rules, and the review moves through the family one link at a time.

How did Polish citizenship pass from parents to children?

The rule depends on the year the child was born.

• Born before 19 January 1951 (1920 act). A child born in marriage took the father’s citizenship; a child born outside marriage took the mother’s. A foreign woman who married a Polish citizen became Polish herself. The act set no condition about the place of birth.
• Born from 19 January 1951 (1951 and 1962 acts). A child could take Polish citizenship from either parent. Where one parent was Polish and the other a foreign citizen, the parents could choose the foreign citizenship for the child by a joint declaration shortly after the birth, and the 1951 act set an extra condition for such children born abroad. These cases are reviewed on the records of the particular family.
• Born under the 2009 act. A child is Polish if at least one parent is a Polish citizen, with no option to choose otherwise.

For births before 1951 this means the parents’ marriage record is as important as the child’s birth record, because the marriage decides whether the father’s citizenship passed on.

Is there a generational limit?

No. None of the four acts limits the number of generations. Confusion sometimes comes from Article 56 of the 2009 act, which says the application must contain the details of the person concerned and of the “ascendants up to the second degree”, that is, parents and grandparents. This is a rule about what information goes into the application, not a limit on how far back the claim can reach. The official application form has a separate section for “further ascendants, including great-grandparents” when the applicant relies on their Polish citizenship.

In practice the limit comes from the evidence. Each link has to be documented, and each ancestor has to have kept Polish citizenship until the next generation was born.

What could break the chain?

The most common question is what happened when an ancestor emigrated and took another citizenship. The answer has changed over time.

From 19 January 1951, naturalization abroad did not by itself end Polish citizenship. Under Article 11 of the 1951 act, a Polish citizen could acquire a foreign citizenship only with the permission of the Polish authorities to change citizenship, and citizenship was lost when both happened: the permission was granted and the foreign citizenship acquired. The 1962 act kept a similar rule until the end of 1998. From 1 January 1999 Polish citizenship can be lost only by voluntary renunciation with the consent of the President of Poland. So an ancestor who became an American, British or Israeli citizen in the 1950s, 1960s or later, without such permission, may have remained Polish, and so may the children born after the naturalization.

Before 1951 the rules were different. Under Article 11 of the 1920 act, acquiring a foreign citizenship generally ended Polish citizenship, and the same act contained special provisions for men liable to military service. Men who were naturalized in the United States or served in the US army before 1951 therefore need an individual review of their records: dates of naturalization, age, military status. The same applies to children who held a second citizenship from birth. In a judgment of 4 November 2025 (II OSK 1048/23), the Supreme Administrative Court held that a girl born in Brazil in 1932 to a Polish father did not lose Polish citizenship merely because she also became Brazilian at birth. This is one judgment, and each family is assessed on its own records.

Families who left Poland for Israel in 1958–1959 or in 1968–1969 also need an individual review of the documents connected with their departure, since the outcome depends on what exactly was filed and decided at the time.

Polish citizenship by descent before 1920: ancestors who emigrated early

Many families in the United States, Canada and the United Kingdom descend from people who left Polish lands before the First World War, when those lands were divided between Russia, Austria-Hungary and Prussia. Polish citizenship itself was created by the act of 20 January 1920, which came into force on 31 January 1920 (Dziennik Ustaw 1920, No. 7, item 44).

Under Article 2 of that act, Polish citizenship went to every person “settled” in the Polish state who did not hold the citizenship of another state. The act defined “settled” by a legal tie to a local community, and the test differed by region:

• former Kingdom of Poland (Russian partition): entry, or the right to entry, in the books of the permanent population;
• former Austrian or Hungarian lands, including Galicia: the right of domicile (Heimatrecht, prawo swojszczyzny) in a municipality;
• former Prussian lands: permanent residence there as a German citizen since before 1 January 1908;
• other lands of the former Russian Empire, such as Volhynia: registration in an urban or rural municipality or in an estate organization.

So leaving before 1920 does not by itself close the door.

What usually decides the matter is foreign naturalization. An ancestor who became an American, Canadian or British citizen before 31 January 1920 held another citizenship on that day and did not become Polish under Article 2. The Supreme Administrative Court has applied the same reasoning to children born abroad before 1920 who were foreign citizens by birth (II OSK 1176/16, 6 March 2018). An ancestor who naturalized after 31 January 1920 first became Polish, and the rules on loss described above then apply.

Proving the 1920 tie needs local records, such as population books or municipal domicile registers. The text of the 1920 act quoted here was checked against the official publication on 3 November 2026.

How to get Polish citizenship by descent: the confirmation procedure

The procedure is called confirmation of Polish citizenship (potwierdzenie posiadania obywatelstwa polskiego). It does not grant anything new; it establishes, by an administrative decision, that the person is a Polish citizen under the earlier laws.

Who decides. The decision is made by a voivode, the head of the central government’s administration in a Polish region. The competent voivode is the one for the person’s place of residence in Poland, or the last place of residence there. If the person has never lived in Poland, which is the usual situation for a descendant born abroad, the case goes to the Masovian voivode in Warsaw.

Where to file. The application is addressed to the voivode. A person living outside Poland may file it through the Polish consul responsible for his or her place of residence, and the consul forwards the application and documents to the voivode without delay.

The form. The application is made on the official form (Regulation of the Minister of the Interior of 7 August 2012) and is filled in in Polish, in block capitals. It asks for details of the person concerned, both parents and all four grandparents, and, where the claim relies on them, great-grandparents and earlier ancestors. It also asks for short biographies: places of residence, work and military service, the circumstances of leaving Poland, changes of name, and any foreign citizenships with the dates they were acquired. Every field must be completed; where a fact is not known, the form is marked “NIEZNANE” (unknown).

Deadline. The law gives the voivode six months from the day the application reaches the voivode’s office. This deadline has applied since 1 August 2025. The law does not say how long cases take in practice.

Fee. The stamp duty for a confirmation decision is 277 zł. Under Article 3a of the Stamp Duty Act it is not charged when the application is filed through a Polish consul who collects a consular fee.

Appeal. If the voivode refuses, the decision can be appealed to the Minister of the Interior. Published case files show that disputes of this kind go on to the administrative courts in Warsaw.

Polish citizenship by descent requirements

To have Polish citizenship by descent confirmed, you need to show four things:

1. A Polish ancestor. Someone in your direct line was a Polish citizen. For most families this means an ancestor who became Polish on 31 January 1920, or who was born to a Polish parent after that date.
2. Transmission at every birth. Citizenship passed to each child under the rule in force at the time of the birth: through the father for children born in marriage before 19 January 1951 (children born outside marriage followed the mother), through either parent after that.
3. No break. Nobody in the chain lost Polish citizenship before the next generation was born.
4. Evidence. Each of these facts is supported by documents.

Confirmation has no Polish language test and no residence requirement, and you do not have to give up your current citizenship. You do not need to have lived in Poland or visited it.

What documents do I need for Polish citizenship by descent?

Every detail in the application has to be supported by documents, unless obtaining a document meets obstacles that are hard to overcome. The form names the core evidence: civil status records of birth and marriage. In practice the file usually contains:

• your own birth certificate, and your marriage certificate if your surname has changed;
• a birth and a marriage record for each generation, from you back to the ancestor whose Polish citizenship you rely on. For births before 1951 the parents’ marriage record matters as much as the birth record;
• proof of the ancestor’s Polish citizenship: a Polish passport or ID card, a military record, an entry in a voter list, a consular registration, or, for 1920, a record showing that the ancestor was “settled” in Poland;
• records of what happened after emigration: the dates and documents of any foreign naturalization, because they decide whether the chain held. For the United States these are the naturalization certificate and petition;
• changes of name, where the spelling of a surname changed between generations or countries.

The form also asks whether your ancestors held Polish identity documents, such as a Polish passport or ID card, and which authority issued them and when. A copy of a Polish passport, Polish ID card or earlier voivode’s decision held by one of your parents shortens the form, because the sections about grandparents and earlier ancestors then do not have to be completed.

Documents in a foreign language are filed with a Polish translation made or certified by a Polish sworn translator (tłumacz przysięgły) or by a consul, unless an international agreement provides otherwise.

If your ancestors were born in what is now Ukraine

Between the two world wars a large part of today’s western Ukraine belonged to Poland. Eastern Galicia, with Lviv, Ternopil and Ivano-Frankivsk (then Lwów, Tarnopol and Stanisławów), had been Austrian until 1918. Volhynia, with Lutsk and Rivne (then Łuck and Równe), had been part of the Russian Empire. From the early 1920s until 1939 these lands formed Polish voivodeships, and most people living there were Polish citizens. If your grandparents or great-grandparents were born there and left before the Second World War, their Polish citizenship may be the start of your chain.

The documents that prove it mostly stayed where they were made. Metric books (registers of births, marriages and deaths), records of Polish passports issued, military registration records, voter lists, school records and house registers are held in the state archives of the Lviv, Ternopil, Ivano-Frankivsk, Volyn and Rivne regions, and in the Central State Historical Archive of Ukraine in Lviv, which holds most of the older Galician metric books. Part of the registers was moved to Poland after 1945, so some searches cover Warsaw as well.

Requests to Ukrainian archives are made in Ukrainian and under Ukrainian rules, and the search often has to be done in the reading room by a person authorized to act for the family. A firm based in Warsaw or the United States usually works through written requests from abroad, and records from these archives are often the part of a Polish case that remains missing. We work with these archives directly: we order the search, obtain the extract or certified copy, and arrange the Polish sworn translation for the voivode.

Jewish families from Galicia and Volhynia. Many Jewish families in the United States, Israel and the United Kingdom come from Lviv, Ternopil, Rivne, Lutsk and the towns around them. The 1920 act granted Polish citizenship regardless of religion or nationality, so the same rules apply. In Galicia, Jewish births and marriages were recorded in separate registers kept under Austrian law. They survive partly in Lviv and partly in Warsaw, so the search usually covers both.

Is a Polish passport by descent the same thing?

A Polish passport is the result most families have in mind, but the legal step that comes first is the confirmation decision. It establishes that you are a Polish citizen; the passport is then applied for as a separate procedure.

Polish dual citizenship: do I have to give up my other passport?

No. Polish law does not require you to give up another citizenship. Under Article 3 of the 2009 act, a Polish citizen who also holds another citizenship has the same rights and obligations towards Poland as a person who is only Polish, and in dealings with the Polish authorities he or she is treated as a Polish citizen. Today Polish citizenship is lost only by voluntary renunciation with the consent of the President. Whether your other country allows dual citizenship is a question of that country’s law.

What if the chain was broken?

If an ancestor did lose Polish citizenship before the next generation was born, confirmation is not available through that line. Two other routes are often mentioned, and each has its own scope.

Restoration (przywrócenie obywatelstwa polskiego) is available only to the person who personally lost Polish citizenship before 1 January 1999 on the grounds listed in Article 38 of the 2009 act. The application goes to the Minister of the Interior, through a consul for people living abroad. A descendant who was never a Polish citizen cannot restore an ancestor’s citizenship. If the minister sees from the documents that the applicant may never have lost citizenship at all, the case is passed to the voivode for confirmation instead.

The Karta Polaka (Card of the Pole) is a document confirming belonging to the Polish nation, not citizenship. It depends on the Polish nationality of a parent, a grandparent or two great-grandparents rather than on their citizenship, and it was originally intended for people of Polish origin in the former USSR.

Some families from the eastern borderlands have a second line to look at. If your family lived in Bukovina between the two world wars, the region was part of Romania at the time, and Romanian citizenship may also be open to you.

How ORIGO works on Polish cases

We start by checking the ancestral chain: for each generation we identify the law that applied to the birth and to any emigration or naturalization, and we mark the documents that are missing. Where records are missing, we search for them in Polish and foreign archives. When the chain holds, we prepare the application on the official form, arrange sworn translations, and handle the confirmation case with the voivode, including any appeal to the Minister of the Interior.
