Summary

Section 31 of the Czech Citizenship Act provides a declaration route for certain children and grandchildren of Czech or Czechoslovak citizens. It can create Czech citizenship even when the applicant did not already inherit citizenship at birth. This makes it different from a citizenship-certificate case, which only confirms an existing unbroken status.

The current official consular guidance says the qualifying relative can be a parent or grandparent who is a current citizen or a qualifying former Czech or Czechoslovak citizen. The applicant cannot be a Slovak citizen on the declaration date. The route does not extend automatically to a great-grandparent or more distant ancestor, although a closer relative may independently have acquired or retained citizenship and thereby become the qualifying parent or grandparent.

Historic exclusions are important. A Czech or Czechoslovak birthplace does not prove eligibility, and some ways in which citizenship ended are expressly outside the Section 31 former-citizen branch.

Eligibility

The principal descendant requirements are:

The official New York consular guidance identifies excluded histories for the general former-citizen branch. These include loss under the presidential constitutional decree concerning Czechoslovak citizenship of persons of German or Hungarian nationality; loss under the Czechoslovakia-USSR agreement concerning Transcarpathian Ukraine; and specified Czech-versus-Slovak republican citizenship situations. The wording is technical and the historical record controls, so a family description such as “Sudeten German,” “from Slovakia” or “from Subcarpathian Rus” should trigger record review rather than an immediate conclusion.

The relative does not always have to be deceased or to have lost citizenship. Official 2026 guidance expressly describes a parent or grandparent who is a current or former citizen. If the relative is current, documents showing the current status and the family line remain necessary. If the relative was a former citizen, a foreign naturalization certificate, Czechoslovak release document or official citizenship determination may establish the loss date and basis.

For a minor, a parent can make the declaration. The official guidance requires additional items in relevant cases, including the other parent's notarized consent and the written consent of a child over 15, subject to listed exceptions. Families should use the current minor checklist rather than assuming an adult's file can simply be copied.

What This Route Allows

When a valid declaration is accepted and the acquisition document is issued, the declarant acquires Czech citizenship without ordinary naturalization. Czech permanent residence, years of physical presence, the B1 language test and the naturalization civic test are not the core conditions of this declaration route.

The new citizen can register required civil events and apply for Czech identity and passport documents. Czech citizenship generally can coexist with another nationality under Czech law, but the other country's law must be checked separately.

The route may also be used for a qualifying minor through the statutory representation process. A parent's successful declaration does not automatically prove that every adult child or sibling has acquired citizenship; each person needs the correct legal basis and application.

What This Route Is Not

Section 31 is not unlimited citizenship by ancestry. A great-grandparent alone is outside the stated parent-or-grandparent reach. It is also not based merely on a Czech birthplace, a Czechoslovak passport-looking document, a surname, property ownership or ethnic identity.

This is not a way for a current Slovak citizen to add Czech citizenship under the descendant branch. The official rule focuses on citizenship held on the declaration date, so a person considering any change to Slovak status should obtain individual advice about both countries' consequences rather than act on a pathway summary.

It is not the special Section 32 route. Section 32 concerns a rare person who remained a CSFR citizen at the end of 1992 but was neither Czech nor Slovak, and that person's direct descendants. It can be relevant to some Transcarpathian histories that Section 31 excludes, but the exact 31 December 1992 citizenship status must be proven.

Finally, the declaration is not a low-document process. It avoids naturalization conditions, but civil records, citizenship proof, loss evidence, identity documents, Czech forms, authentication and certified Czech translations can make the file substantial.

Next Steps

  1. Identify the closest possible qualifying relative and confirm whether that person is your parent or grandparent.
  2. Obtain official proof of the relative's current or former Czech/Czechoslovak citizenship. Do not use birthplace alone as a proxy.
  3. If citizenship ended, obtain the exact loss document and date. Compare the legal basis with the official exclusion list.
  4. Collect long-form civil records for each family link and records explaining marriages, adoptions, divorces or name changes.
  5. Obtain current proof that you are not a Slovak citizen in the form required by the receiving office.
  6. Ask the Czech diplomatic mission or competent Czech office for its current Section 31(3) forms, document list, fee, appointment and filing rules. Foreign public records may need an apostille or superlegalization and certified Czech translation.
  7. For a minor, obtain the current parent-consent and age-15 consent forms and verify whether an exception applies.
  8. After acquisition, complete any required Czech special-register entries before applying for a passport or other citizen document.
