Before you start
What the family records need to show.
Polish citizenship by descent depends on the facts of each generation, not only on having a Polish ancestor. In broad terms, an application to confirm citizenship asks whether the ancestor held Polish citizenship, whether it passed to the next generation under the law in force at the time, and whether anyone in the line lost it. The guides above explain these questions in general terms. They are not legal advice, and an individual case should be checked with a lawyer or a Polish consulate. British readers can start with Polish citizenship by descent for British citizens.
Our part is the documentary side. The evidence usually starts with Polish records from after January 1920, when the first Polish citizenship act was adopted, and then links each generation through birth and marriage certificates. Pre-war passports, identity documents, military papers and population registers can show how an ancestor was treated by the Polish authorities, while British naturalisation files show whether and when another citizenship was acquired.
Preparing the evidence
- Draw the line from the Polish ancestor to you, with dates of birth, marriage and emigration for each generation.
- Gather the certificates you already hold in the UK, including marriage and naturalisation records.
- Identify Polish documents from after 1920 that show the ancestor’s status, such as a passport, an identity card or a military record. See pre-war passport and ID applications.
- Fill the gaps in the archives where a Polish birth or marriage entry is missing.
- Have the complete file assessed by a lawyer or a Polish consulate before you apply.
Common questions
Who decides whether I am a Polish citizen?
Confirmation of Polish citizenship is decided by a voivode, the government’s regional representative in Poland. Applicants living abroad can usually submit the application through a Polish consulate. The decision rests on the documents supplied.
Is restoration the same as confirmation?
No. Confirmation applies to people who already hold Polish citizenship by descent but have no document proving it. Restoration is a separate procedure for people who held Polish citizenship and lost it. The restoration guide explains the difference.
Do British documents need to be translated?
Foreign documents submitted to Polish authorities normally need a translation into Polish by a sworn translator, and British certificates may also need an apostille. Check the current requirements with the office handling your application.
