Czech Citizenship by Descent
Czech citizenship can be claimed by descendants of Czech or Czechoslovak citizens through several pathways. Direct descent through a Czech citizen parent is the most straightforward route. A separate declaration process exists for those whose ancestors were expelled or lost citizenship under post-war decrees, Nazi policies, or the 1993 Slovakia-Czech separation. Persons of Czech origin may also qualify for permanent residency as an intermediate step.

Who qualifies for Czech citizenship by descent
If a parent was a Czech citizen when you were born, you are already Czech and only need to register. If a parent or grandparent was a Czech or Czechoslovak citizen who lost that citizenship by 31 December 2013 — for any reason, including naturalising in the United States or elsewhere — you can acquire Czech citizenship by a simple declaration under Section 31(3) of Act No. 186/2013 (as amended in 2019). It is a legal entitlement: no language test, no residence, and you keep your existing citizenship. The route stops at grandchildren; a proposed great-grandchild extension had not been enacted as of September 2026. People of Czech origin who fall outside it can apply for permanent residence in the Czech Republic.

The declaration route covers most Czech-American families
Since a 2019 amendment, Section 31(3) of the Citizenship Act (No. 186/2013) lets the child or grandchild of a former Czech or Czechoslovak citizen acquire Czech citizenship by declaration, provided that ancestor lost citizenship by 31 December 2013. It does not matter how the citizenship was lost. Naturalising in the United States, Canada or Australia counts, and that is how most Czech emigrants lost it.
It is a legal entitlement rather than a discretionary grant: no language test, no residence, no interview. And because the Czech Republic has allowed dual citizenship since 2014, you keep the citizenship you already hold.
Children of Czech citizens are already Czech
If a parent was a Czech citizen when you were born, you do not need the declaration at all. You are Czech by birth and only need to register the birth with the Czech special registry in Brno, usually through a consulate.
Where the line stops
The declaration reaches children and grandchildren only. A proposal to extend it to great-grandchildren had not become law as of September 2026, whatever some websites say. If your connection is further back, the realistic option is permanent residence for persons of Czech origin, followed in time by naturalisation.
Watch the 1993 split. Czechoslovakia divided on 1 January 1993, and an ancestor who lived on the Slovak side may have become a Slovak citizen. That points you to the Slovak route instead.
Documents, cost, timeline
You need birth and marriage certificates linking you to the ancestor, proof of the ancestor's Czech or Czechoslovak citizenship (a birth record from a Czech registry, a pre-war passport, or a domovský list), and evidence of when they lost it, such as a naturalisation certificate. Foreign documents need apostilles and official Czech translations.
Declarations can be filed at a Czech consulate or a regional office. There is a small administrative fee, and decisions typically take several months.

Czech processing times
Direct descent cases where a parent was Czech can be resolved in 3-6 months. Declaration cases are more complex and may take 6-18 months depending on the regional office and document availability. Permanent residency applications for persons of Czech origin follow a separate immigration timeline.
Where Czech claims go wrong
- Assuming the declaration only covers involuntary losses — it covers any loss by the end of 2013, including naturalising in the US
- Trying to claim through a great-grandparent — not covered
- An ancestor who became Slovak rather than Czech in 1993
- Missing proof of the ancestor's Czechoslovak citizenship and of when it was lost
- Name spellings that differ between Czech, German and English records

Czech citizenship FAQ
My grandfather became an American citizen. Can I still get Czech citizenship?
Yes, if he was a Czech or Czechoslovak citizen and lost that citizenship by 31 December 2013. The Section 31(3) declaration covers losses for any reason, including naturalising in the US.
Can I claim through a great-grandparent?
Not by declaration. The route covers children and grandchildren only, and the proposed great-grandchild extension had not been enacted as of September 2026. Permanent residence for people of Czech origin is the alternative.
Do I need to speak Czech?
No. The declaration has no language test and no residence requirement.
Will I have to give up my current citizenship?
No. The Czech Republic has permitted dual citizenship since 1 January 2014.
Czech nationality law
Czech citizenship is governed by Act No. 186/2013 Coll. on Czech Citizenship (zákon o státním občanství), effective 1 January 2014. The declaration route for descendants of expelled Czechoslovaks is primarily governed by Act No. 193/1999 Coll. (on the citizenship of some former Czechoslovak nationals). The 1993 division of Czechoslovakia was governed by Constitutional Act No. 542/1992.
Dual citizenship in the Czech Republic
The Czech Republic fully permits dual citizenship since the passage of Act No. 186/2013. Prior to 2014, Czech law generally prohibited dual nationality. If your ancestor lost Czech citizenship before 2014 under the old prohibition, they may need to apply for restoration. New Czech citizens are not required to renounce prior nationality, and Czech citizens who naturalise abroad no longer automatically lose Czech citizenship.
Czech application costs
Declaration of citizenship fee: CZK 500 (~€20). Recognition of citizenship at a Czech consulate: free. Document costs (apostilles, certified translations into Czech): €400–€900 depending on number of countries. Attorneys or Czech citizenship specialists: €1,500–€4,000.

Michael Soucek— Claimed Hungarian citizenship by descent firsthand
Founder & Researcher, Heritage Passport Finder
I built Heritage Passport Finder after going through the process of claiming Hungarian citizenship by descent myself. Tracing my family's records and working out what actually qualified turned into a genuine obsession with how citizenship-by-descent law works across Europe, so I started gathering what I learned in one place. I'm not a lawyer, and I don't treat these guides as the final word — citizenship law changes constantly and differs by country, so every page points to official sources and I recommend confirming your own case with the relevant consulate or an immigration attorney. What I can offer is a clear map of the landscape, drawn from official sources and the experience of someone who has actually been through it.
