Adoption

1 path in this category

Adoption-based naturalization (full adoption)

Full adoption (пълно осиновяване only — not непълно) of a non-citizen by a Bulgarian citizen confers no citizenship automatically (ЗБГ чл. 6); the adoptee naturalizes via one of two overlapping tracks — чл. 15(1) т. 2 (waives чл. 12(1) т. 2,4,5,6; retains т. 1 adult + т. 3 clean record) or the more favorable чл. 18(2) (on чл. 18(1) conditions, WITHOUT any чл. 12 conditions). Adoptee must have been under 18 at the adoption application (СК чл. 77(1)); a foreign decree needs КМЧП recognition.

Birth

1 path in this category

Citizenship by birthplace / foundling

A person born on Bulgarian territory who does not acquire another citizenship по произход is a Bulgarian citizen by place of birth (conditional jus soli — anti-statelessness, NOT pure 'otherwise stateless'); a foundling found on territory with unknown parents is deemed born on territory and so acquires citizenship automatically. Declaratory (ex lege at birth, certified via чл.39), loss-protected (чл.22/24 reach naturalisation only; Const. чл.25(3)). Operationalises the 1961 Reduction Convention (Art.1 ↔ чл.10, Art.2 ↔ чл.11; BG PARTY 2012).

Child

1 path in this category

Minor follows naturalizing/accepting parent

A minor acquires Bulgarian citizenship derivatively from a parent: under чл. 17, a child <14 follows a parent who acquires/accepts citizenship (or one parent who does so while the other is already Bulgarian), and a child 14–18 follows only on the child's own request; under чл. 18(1), a child <14 of one Bulgarian-citizen parent who does not already hold Bulgarian citizenship may acquire WITHOUT the чл. 12 conditions on written parental consent (consent of a parent deprived of parental rights not required), 14–18 on own request; under чл. 28, the same derivative mechanism operates on a parent's RESTORATION of citizenship. No 5-year residence, income, language or renunciation requirement is imposed on the child. Full adoption is excluded (чл. 6; adoptees use чл. 18(2)). Dual nationality is tolerated (чл. 3). Decided by presidential указ on MoJ proposal via the Council on Citizenship. As of ЗБГ ДВ бр. 61/29.07.2025.

Descent

3 paths in this category

Citizenship by descent (jus sanguinis, one-parent) — Art. 8 Bulgarian Citizenship Act

At least one parent is a Bulgarian citizen at the moment of the person's birth (чл. 8) → the person IS a Bulgarian citizen by origin ex lege, from birth — gender-neutral, no residence/registration/place-of-birth precondition, no generational cap on the statute's face (practical limit is evidentiary). Where the parental link is undocumented, чл. 9 allows it to be established by acknowledgment (припознаване) or court ruling, after which чл. 8 applies. Status is certified (not conferred) by the declaratory чл. 39 MoJ certificate; as a citizen by birth the person cannot be deprived (Const. чл. 25, ал. 3) and may hold another nationality (чл. 3).

Citizenship by descent — born abroad (ЗБГ Art. 8 ex lege; Art. 39 declaratory certificate)

A child born abroad to ≥1 Bulgarian-citizen parent is Bulgarian from birth by чл. 8 (ex lege); there is no 'registration to acquire' and no acquisition deadline — чл. 39 only certifies the pre-existing status. Pre-1999 chains are read against the era-specific lineage law in force at each birth (КС № 12/1996 birth-moment rule), with the 1968 чл. 6 transmission asymmetry relevant to births abroad before the 1986/1989 amendments.

Citizenship by descent — paternity/parentage establishment by acknowledgment or court decision (ЗБГ Art. 9)

Descent is also established for a person acknowledged (припознат) by a Bulgarian citizen or whose origin from a Bulgarian citizen is established by court decision; Bulgarian citizenship then follows ex lege under чл.8. The court/registry establishes the parentage FACT, not the citizenship status itself (чл.4). Acquisition is declaratory; the чл.39 MoJ certificate confirms the pre-existing status.

Historical

3 paths in this category

Bulgarian-origin facilitated naturalization (Art 15(1)(1))

A non-Bulgarian-citizen 'of Bulgarian origin' naturalizes by the constitutional облекчен ред (чл.25(2) КРБ) under ЗБГ чл.15(1)т.1, waiving чл.12(1) т.2,4,5,6 (no 5-yr residence clock, no income, no language, no renunciation) and retaining only т.1 (adult) and т.3 (clean Bulgarian-court record). Origin = at least one ascendant who is 'българин' (§2(1) ДР); documentary proof reaches 3rd degree (чл.15(2)) while the definitional reach is 4th degree (ВКС №495/2025), with the ascendant's own citizenship irrelevant. The 2021 amendment removed the mandatory standalone origin certificate; origin is now established within the procedure. Dominant BG-MK and BG-TR diaspora route; not a Sephardic statute.

1989-expelled restoration (Revival-Process cohort + descendants)

Persons (and descendants) of the 1984–89 Revival Process / 1989 'Big Excursion' cohort (310k–322k expelled; ~360k inc. family — a RANGE) reacquire Bulgarian citizenship through the LIVE paths of чл.15(1)т.1 origin naturalization (descendants of Bulgarian origin, waiving residence/income/language/renunciation; proof of ascendant ≤3rd degree per чл.15(2), definitional reach to 4th degree per ВКС №495/2025) or standing Chapter Four чл.26 restoration of a released person (with чл.26(2) exempting persons of Bulgarian origin from the 3-yr residence requirement; чл.28 for minor children). The express §4 ПЗР 1989-emigrant restoration window (citizens released without request who emigrated to a no-emigration-agreement Türkiye) is LAPSED (~20.02.2000). Restoration is Chapter Four чл.26–28, NEVER §22–27. Bulgaria tolerates dual nationality (чл.3).

Acquisition/recognition under prior Bulgarian statutes (1903/04 → 1940 → 1948 → 1968), ex lege per the КС №12/1996 birth-moment rule — NOT Sephardic

Bulgarian citizenship is acquired EX LEGE at the moment of birth under the prior statute in force at that moment (1903/04 / 1940 / 1948 / 1968 Act), by the claimant or his ascendant in an unbroken descent chain, per the КС №12/1996 'по право в момента на раждането' temporal rule [BG-EVID-006; BG-EVID-007; BG-EVID-016; BG-SRC-025 T1]; the status, judged link-by-link under each era's law, descends to the present claimant and is RECOGNIZED (not granted) via the declaratory чл. 39 MoJ certificate (чл. 2 inter-temporal anchor) [BG-EVID-027]. Era tests differ (1948 Act required BOTH parents; the pre-1986 1968 Act treated mother-vs-father transmission unequally). § 3 ПЗР auto-restored 1940/1948-deprived ascendants on 20.02.1999. EXCLUSIONS: new-lands (Thrace/Macedonia/Pirot) populations and WWII deportees were NEVER BG citizens → cannot recognize; merely-ethnic-Bulgarian claimants whose ascendant never held citizenship must use чл. 15 origin (HIS-01). NOT Sephardic (no discrete statute).

Investment

Investment citizenship (Art. 12a + Art. 14a) — REPEALED

CLOSED historical pathway. Investment citizenship by two distinct articles — чл. 12а (standard ~5-yr; ≥1,000,000 BGN) and чл. 14а (fast-track ~1-yr; ≥2,000,000 BGN or priority-project/job variants), both introduced ДВ бр. 16/2013 and both repealed by ДВ бр. 26/2022 (golden-passport abolition, в сила ~05.04.2022). §7 ПЗР terminated pending proceedings; §8 ПЗР retained prior grantees conditionally (revocable for non-maintenance); §9 ПЗР ordered a ДАНС 6-month mass review (→17 revocations, 04.05.2023). C-181/23 (29.04.2025) confirms post-repeal EU-law incompatibility of transactional CBI (confirmatory only — BG already repealed). NOT '2009'; NOT 'ДВ 21/2022'; NOT a single article. '~12,500 applicants' REFUTED (~452 apps / ~93 grants). No CBI in live ЗБГ to ДВ бр. 61/2025. As of 2026-06-13.

Marriage

Marriage-based facilitated naturalization (spouse of a Bulgarian citizen, ЗБГ чл.13 т.1)

Facilitated naturalization for the foreign spouse of a Bulgarian citizen: a ≥3-year permanent/long-term residence permit + a ≥3-year subsisting legal marriage to a Bulgarian citizen, meeting чл.12(1) т.1,3,4,5 (age, clean record, income, language) but with the чл.12(1) т.6 renunciation requirement WAIVED for spouses by чл.12(2) т.1 (so dual nationality is permitted). Marriage alone confers nothing automatically (чл.5); anti-sham scrutiny via чл.19/29/33/22 and the upstream ЗЧРБ фиктивен-брак screen.

Military service — negative evidence (no military-service citizenship route)

BG-MIL-01 is a NEGATIVE/absent route: there is no rule-based military-service entitlement to Bulgarian citizenship. A foreign serviceman could be naturalized only via the discretionary чл.16 special-merit/state-interest route (BG-NAT-04), where the Minister of Defence would be the competent proposing minister under чл.30.

A foreigner who has held refugee status (статут на бежанец) or presidential asylum (убежище) for ≥3 years before filing, and who meets чл.12 ал.1 т.1, 3, 4 и 5 (adult, clean record, income, Bulgarian language), may acquire Bulgarian citizenship by facilitated naturalization under чл.13а ал.1 — with no separate 5-year residence clock (т.2) and no renunciation of prior citizenship (т.6).

Stateless naturalization — reduced residence (ЗБГ Art. 14)

A stateless person (лице без гражданство) who has held a permanent or long-term residence permit for ≥3 years and meets чл.12(1) т.1,3,4,5 may naturalize under чл.14; the 5-year clock (т.2) is reduced to 3 years and the renunciation requirement (т.6) is moot. Distinct from BG-SPC-01 only by framing/storage layer (same article чл.14): SPC-01 foregrounds the ЗЧРБ SDP recognition gateway, NAT-03 foregrounds the reduced-residence naturalization grant.

Special-merit / state-interest naturalization (Art 16 BCA)

Discretionary naturalization WITHOUT any чл.12 conditions where Bulgaria 'има интерес' or the person has 'особени заслуги' in the public/economic sphere, science, technology, culture or sport; the proposal is made by the competent minister (NOT the individual) under чл.30 with prior written consent and a motivated statement of the concrete interest/contribution (чл.30(2) нова ДВ бр.21/2021).

Restoration of Bulgarian citizenship after deprivation / lapsed basis (Art. 27 ZBG)

Restoration for a former NATURALIZED citizen DEPRIVED (лишено) of Bulgarian citizenship under чл. 24, where it is established that there was no ground for the deprivation or the ground has lost its significance (чл. 27 ЗБГ). No criminal-record or residence-permit condition (unlike чл. 26). Children follow derivatively (чл. 28). Decided by Presidential decree on the Minister of Justice's proposal (6-month proposal deadline, чл. 35(1) т. 3). The REVOKED-naturalization (чл. 22) cohort has no чл. 27 track.

Stateless-person naturalization (Art. 14 ZBG) via the Statelessness Determination Procedure (SDP, FRBA Arts 21b–21g)

A recognized stateless person who has held a permanent or long-term residence permit for ≥ 3 years and meets ЗБГ чл. 12(1) т. 1,3,4,5 (adult; clean Bulgarian criminal record; self-support; Bulgarian language) may naturalize under Чл. 14, with the 5-year clock (т. 2) replaced by the 3-year clause and the renunciation requirement (т. 6) waived. The route is distinguished from the identically-anchored NAT-03 framing by its upstream ЗЧРБ Statelessness Determination Procedure (чл. 21б–21ж) gateway, which produces the recognized-stateless status.

Voluntary renunciation / release from Bulgarian citizenship (Art 20 ZBG; Constitution Art 98(9))

A Bulgarian citizen permanently resident abroad (>9 mo/calendar year, excl. state/spouse service or studies, §2 т.2 ДР) may voluntarily request release (освобождаване) from Bulgarian citizenship under ЗБГ чл. 20, provided he has already acquired a foreign nationality or has an open procedure to acquire one (anti-statelessness). Children's release follows чл. 21. Granted by presidential указ on MoJ proposal (6-month deadline, чл. 35(1) т. 4).

Revocation of naturalization (Art 22) and deprivation of citizenship (Art 24) + terrorism exclusion

Involuntary loss of Bulgarian citizenship reaching ONLY naturalized citizens (Конституция чл.25(3) absolutely bars deprivation of birth-citizens). Revocation of naturalization (отмяна, чл.22) for judicially-established false data (т.1), concealment of disqualifying data (т.2) or failure to notify a чл.32а change (т.3) — admissible only within 10 years of acquisition and only if the person is not left stateless, EXCEPT a terrorism carve-out (чл.22(2)) that removes the 10-year bar where the facts relate to participation in terrorism (1-month expedited track в сила 31.01.2026). Deprivation (лишаване, чл.24) where a naturalized citizen abroad is finally convicted of a grave crime against the Republic and is not left stateless. No spillover to spouse/children (чл.23/чл.25). Effected by presidential указ; constrained by EU-law proportionality (TFEU Art 20). The former investment-non-maintenance revocation ground (чл.22(1)т.4) was repealed by ДВ бр.26/2022.
