the qualifying ancestor must have held czech citizenship at the moment the applicant was born, passing it down the line by descent.

- § Act No. 186/2013 §31 cutoff — qualifying ancestor must have lost Czech / Czechoslovak citizenship on or before 31 Dec 2013
- § Constitutional Decree No. 33/1945 (Beneš Decrees) — exclusion: loss under Decree 33 does not found a §31 claim

- relationship:

the applicant must be the grandparent of the qualifying ancestor.

ANY of the following
the qualifying ancestor has a qualifying citizenship loss after cutoff (occurred). If this fact is absent, the rule treats it as not applying (rather than asking for more information).
- occurred:
- true
the qualifying ancestor has a qualifying czech citizenship never lost (occurred). If this fact is absent, the rule treats it as not applying (rather than asking for more information).
- occurred:
- true
Primary sources
- § Act No. 186/2013 on Czech citizenship, §31(1) + §84 — the declaration reaches only a person who lost Czech/Czechoslovak citizenship before the Act took effect on 1 January 2014, so a later loss (or no loss at all) closes this route
- § Act No. 186/2013 §40(1) — from 1 January 2014 the only loss of Czech citizenship is a declaration of renunciation, conditional on permanent residence abroad and holding a foreign citizenship; the automatic loss on voluntary foreign naturalisation under Act No. 40/1993 Sb. §17(1) ceased with that Act on 31 December 2013
- § Act No. 186/2013 §4 — a child acquires Czech citizenship at birth if at least one parent is a Czech citizen on the day of birth (no generational cap, no registration, no deadline)
- § Act No. 186/2013 §42(3), §43 — a direct-line relative may apply for a certificate of citizenship (osvědčení) concerning a DECEASED person, and the certificate states when, how and under which provision citizenship was acquired or lost

- holds:
- true
Primary sources
- § Act No. 186/2013 on Czech citizenship, §31(3) — the declaration is barred only while the declarant IS a citizen of the Slovak Republic ON THE DATE of the declaration; a current-status test, not a lifetime bar (contrast §32(2), which uses the past tense)
- § Zákon č. 40/1993 Z. z. o štátnom občianstve Slovenskej republiky, §9(1)(a), §9(2), §9(3), §9(11) — release from Slovak citizenship on application, conditional on holding or being promised another citizenship, blocked during criminal proceedings or with tax/social-insurance arrears, and effective on receipt of the release document

the qualifying ancestor has a qualifying retains slovak ssr citizenship post 1969 (still retains). If this fact is absent, the rule treats it as not applying (rather than asking for more information).
- still retains:
- true
Primary sources
- § Act No. 186/2013 on Czech citizenship, §31(1) final limb — excludes an ancestor who acquired Slovak SSR / Slovak Republic citizenship after 1 January 1969 AND IS STILL its citizen; the retention element is in the present tense
- § Zákon č. 40/1993 Z. z. o štátnom občianstve Slovenskej republiky, §9(1)(a), §9(11) — Slovak citizenship is lost on release, effective on receipt of the release document, so the excluded status can end

the applicant must be the grandparent of the qualifying ancestor.
- relationship:

the qualifying ancestor has a recorded retains slovak ssr citizenship post 1969 such that still retains = false, acquired post 1969 = true. If this fact is absent, the rule treats it as not applying (rather than asking for more information).
- still retains:
- false
- acquired post 1969:
- true
Primary sources
- § Act No. 186/2013 on Czech citizenship, §31(1) final limb — on the statutory text the exclusion requires acquisition of Slovak SSR / Slovak Republic citizenship after 1 January 1969 AND continued retention, so an ancestor who has since lost it is not excluded
- § Czech Consulate General Los Angeles, official §31 page — renders the same limb disjunctively (acquired after 1 January 1969 OR still a Slovak citizen); the divergence from the statutory text is unresolved and front-line practice may be stricter

Primary sources

- § Constitutional Decree No. 33/1945, §1(3), §1(4), §2(1) — the Decree did not apply to those who declared as Czechs or Slovaks, nor to those coerced into declaring otherwise, and citizenship was preserved for those who stayed loyal to the Republic
- § Government Regulation No. 76/1948 Sb. §1; Act No. 245/1948 Sb. §1(1); Act No. 34/1953 Sb. §1(1)-(2) — restoration of citizenship to the Decree-33 cohort, the last of these ex lege and without any application for Germans resident in Czechoslovakia, extended to spouses and minor children

- § Treaty No. 186/1946 Sb., Protocol Art. 2, and Government Regulation No. 61/1945 Sb. §1, §3 — persons of Czech and Slovak nationality domiciled in Transcarpathian Ukraine could opt for Czechoslovak citizenship until 1 January 1946, an option framed as RETAINING citizenship rather than reacquiring it
- § Act No. 186/2013 §80 items 11-12 — Act No. 193/1999 Sb. and Act No. 46/2006 Sb. are repealed, so no restitution route survives outside §31 and §32

- § Act ČNR No. 39/1969 Sb. §2(1)-(2) — the 1969 allocation ran on two DISJOINT tests: birthplace for those born on Czechoslovak territory, registered permanent residence as at 1 January 1969 (then the last pre-emigration residence of the person or their parents) for those born abroad
- § Act ČNR No. 39/1969 Sb. §4(2)-(3), mirrored by Act SNR No. 206/1968 Zb. §4(1) — a person allocated to the Slovak Socialist Republic could choose Czech republic citizenship by declaration until 31 December 1969; whether that lifts the §31(1) exclusion is unresolved, the qualifier in the repealed Act No. 193/1999 Sb. §7 not having been carried forward
