Citizenship by Descent (Declaration)

To qualify for citizenship by declaration, you must prove a direct bloodline to a former citizen. Eligibility is strictly defined by the date and circumstances under which your ancestor lost their citizenship.

• Direct Descendants (Children and Grandchildren): You qualify if you are the child or grandchild of a former Czech or Czechoslovak citizen who lost their citizenship before January 1, 2014.
• Former Citizens: If you personally held and lost Czech or Czechoslovak citizenship before 2014, you can reclaim it directly.
• The 1918 Threshold: Your ancestor must have been alive and resident in the territory of Czechoslovakia after October 28, 1918. If they emigrated before the formation of the Czechoslovak state, they likely never held the citizenship required to pass it down.
• The "Slovak" Exclusion: If your ancestor became (or would have become) a citizen of the Slovak Republic during the internal reorganization of Czechoslovakia on January 1, 1969, you generally cannot use this Czech pathway. You must prove your ancestor was a citizen of the Czech Socialist Republic side of the federation.
• Territorial Exclusions: You do not qualify if your ancestor lost their citizenship under the Czechoslovak-Soviet Treaty regarding Subcarpathian Rus, or if they lost it due to the post-WWII Benes decrees (specifically targeting those of German or Hungarian ethnicity).
• Generational Limits: The law explicitly covers up to the third generation (grandchildren). Great-grandchildren (the fourth generation) generally only qualify if their parent first reclaims Czech citizenship or if the parent was already a citizen at the time of the applicant's birth.
