How Greek citizenship by descent works
The eligibility rules for Greek citizenship by descent, in plain English — who may qualify, what disqualifies, and the legal regimes over time, each cited to its primary statute.
Who may qualify
A qualifying path — via the jure sanguinis route
Requirements
ALL of the following
ANY of the following
the applicant has a recorded descent path such that requires pre 1984 declaratory = false.
- requires pre 1984 declaratory:
- false
the applicant has a qualifying birth (greek post 1984).
- greek post 1984:
- true
the qualifying ancestor must have held greek citizenship at the moment the applicant was born, passing it down the line by descent. Where the claim runs through more than one generation, a later loss of that citizenship is measured against the birth of that ancestor's own child on the line — the point at which it would have passed down — rather than against the applicant's birth.
- required citizenship:
- greek
the qualifying ancestor has a qualifying municipal register recorded (confirmed).
- confirmed:
- true
Must NOT be true
the qualifying ancestor has a qualifying ancestor subject to art19 stripping (confirmed). If this fact is absent, the rule treats it as not applying (rather than asking for more information).
- confirmed:
- true
Primary sources
- § Law 3284/2004 (Greek Nationality Code), Art. 1 — declaratory citizenship by descent, no generational cap
- § Law 1438/1984 — maternal/paternal-line equalization from 8 May 1984
A qualifying path — via the jure sanguinis automatic pre1984 route

- F
the applicant has a recorded birth such that greek law legitimate = false.
- greek law legitimate:
- false
the qualifying ancestor must have held greek citizenship at the moment the applicant was born, passing it down the line by descent. Where the claim runs through more than one generation, a later loss of that citizenship is measured against the birth of that ancestor's own child on the line — the point at which it would have passed down — rather than against the applicant's birth.
- required citizenship:
- greek
the qualifying ancestor has a qualifying municipal register recorded (confirmed).

Primary sources
- § ΝΔ 3370/1955 (Code of Greek Nationality), art. 1 εδ. α' — a child born of a Greek FATHER is Greek from birth; and art. 1 εδ. γ' — so is a child born of a Greek MOTHER and a father not legally recognised as such ('εξ Ελληνίδος μητρός και πατρός μη νομίμου γεννηθείς'). Same rule earlier at art. 14 εδ. α' and εδ. β' of the ΑΝ of 1856. These, not Law 3284/2004 art. 1, are the provisions under which this cohort acquired Greek citizenship at birth [GR-07]
- § Art. 56 of n. 5143/2024 (ΦΕΚ Α' 161/11.10.2024) replaced art. 26 §1 of the Greek Nationality Code; the replacement enumerates two entirely different cases and no longer reaches the pre-18.7.1982 paternal or pre-8.5.1984 maternal windows
- § Ministry of Interior, General Secretariat for Citizenship, Εγκύκλιος 16 (α.π. 43360, 31.07.2026) — after that replacement 'δεν απαιτείται πλέον η έκδοση απόφασης διαπίστωσης' for former cases (b) and (c), and 'τα τέκνα αυτά αποκτούν αυτοδίκαια την ελληνική ιθαγένεια', completed by ordinary initial registration in the dimotológio rather than by a determination decision
- § The same circular EXCLUDES from automatic acquisition those falling under art. 14(1) and 14(2) of the Code — the pre-8.5.1984 maternal case inside a marriage Greek law recognised, and the pre-18.7.1982 paternal case inside one it did not — which is why this rule turns on whether the marriage was recognised and not on the parent's sex alone
A qualifying path — via the declaration route
Requirements
ALL of the following
ANY of the following
the applicant has a qualifying descent path (requires pre 1984 declaratory).
- requires pre 1984 declaratory:
- true
ALL of the following
the applicant has a recorded birth such that greek post 1984 = false.
- greek post 1984:
- false
the applicant must be the parent of the qualifying ancestor.
- relationship:
- parent
the qualifying ancestor has a recorded sex such that value = F.
- value:
- F
the qualifying ancestor must have held greek citizenship at the moment the applicant was born, passing it down the line by descent. Where the claim runs through more than one generation, a later loss of that citizenship is measured against the birth of that ancestor's own child on the line — the point at which it would have passed down — rather than against the applicant's birth.
- required citizenship:
- greek
the qualifying ancestor has a qualifying municipal register recorded (confirmed).
- confirmed:
- true
Must NOT be true
the qualifying ancestor has a qualifying ancestor subject to art19 stripping (confirmed). If this fact is absent, the rule treats it as not applying (rather than asking for more information).
- confirmed:
- true
Primary sources
- § Law 3284/2004, Art. 14(1) — maternal-line declaration for births before 8 May 1984 (a personal declaration; the live basis for this route) [GR-02]
- § Law 3284/2004, Art. 14(2) — paternal CIVIL-marriage declaration for children born before 18 July 1982 to a Greek father (Law 1250/1982 civil-marriage cutoff) [GR-04]
- § HISTORICAL — Law 3284/2004, Art. 26 cases (b)/(c) as they stood before 11 Oct 2024: born before 18 July 1982 in wedlock to a Greek father, or before 8 May 1984 to a Greek mother where the marriage was deemed invalid. Replaced by art. 56 of n. 5143/2024; retained here because the pack's route and track names still describe the declaratory decision, NOT as a live basis on which a claimant is told they qualify
A qualifying path — via the declaratory decision route
Requirements
ALL of the following
the applicant must be the parent of the qualifying ancestor.
- relationship:
- parent
the applicant has a qualifying paternal recognition as minor (confirmed). If this fact is absent, the rule treats it as not applying (rather than asking for more information).
- confirmed:
- true
the qualifying ancestor must have held greek citizenship at the moment the applicant was born, passing it down the line by descent. Where the claim runs through more than one generation, a later loss of that citizenship is measured against the birth of that ancestor's own child on the line — the point at which it would have passed down — rather than against the applicant's birth.
- required citizenship:
- greek
Must NOT be true
the qualifying ancestor has a qualifying ancestor subject to art19 stripping (confirmed). If this fact is absent, the rule treats it as not applying (rather than asking for more information).
- confirmed:
- true
Primary sources
- § Law 3284/2004 (Greek Nationality Code), Art. 13 — a foreign child born out of wedlock acquires Greek citizenship upon legal recognition (acknowledgement of paternity) by a Greek father while the child is a minor
Cases that need individual review
Needs individual review
Requirements
ALL of the following
the applicant has a qualifying descent path (includes undeclared pre 1984 maternal link).
- includes undeclared pre 1984 maternal link:
- true
Must NOT be true
the qualifying ancestor has a qualifying ancestor subject to art19 stripping (confirmed). If this fact is absent, the rule treats it as not applying (rather than asking for more information).
- confirmed:
- true
Author caveats
- Your claim runs through a relative born before 8 May 1984 to a Greek mother. Until that date Greek citizenship did not pass automatically that way where Greek law recognised the marriage — that relative became Greek only by making a declaration under Article 14(1), and it is still open to them today with no deadline.
- If that declaration was made, the line holds and the ordinary descent route applies. If it was never made, the line does not carry to you, and the relative may be able to make it now. This is the one thing to establish before anything else.
Primary sources
- § Law 3284/2004, Art. 14(1) — a child born before 8.5.1984 to a Greek mother inside a marriage Greek law recognised 'ginetai Ellinas, an dilosei ti scetiki voulisi tou': BECOMES Greek IF they declare. The declaration is constitutive, so an intermediate ancestor who never made it never acquired Greek citizenship and could not transmit it onward [GR-02]
- § Ministry of Interior, General Secretariat for Citizenship, Εγκύκλιος 16 (α.π. 43360, 31.07.2026) — the same cohort acquires AUTOMATICALLY where there was no marriage Greek law recognised ('εξ Ελληνίδος μητρός και πατρός μη νομίμου γεννηθείς', art. 1 εδ. γ' ΝΔ 3370/1955), which is why this rule fires only on the recognised-marriage half
Needs individual review
Requirements
ALL of the following
the applicant has a qualifying parent not registered in dimotologio (confirmed).
- confirmed:
- true
the applicant must have documented greek_national_origin heritage, backed by a formal attestation document (e.g. a community-committee certificate).
- heritage type:
- greek_national_origin
- attestation required:
- yes
Author caveats
- The decisive condition on this route — the consular assessment of Greek national consciousness — is not something a family tree can answer, so this rule reports that the route is open to the applicant rather than deciding it. A specialist read is the next step.
- Whether Art. 10 confers an entitlement once the consulate is satisfied was not established (2026-07-27 consistency audit, finding 5: legal confirmation outstanding). The rule withholds under either reading.
Primary sources
- § Law 3284/2004, Art. 10 (and Art. 15) — naturalization of expatriates of Greek origin residing abroad; PROSPECTIVE (not retroactive from birth)
- § Requires indisputable Greek national origin + 'Greek national conscience' assessed at a mandatory consular interview (Greek language/history/geography/culture)
- § Greek MoI National Registry of Administrative Procedures (en.mitos.gov.gr, Art. 10 of Law 3284/2004) — indisputable national origin is the FORMAL condition and the establishment of national consciousness the ESSENTIAL condition, both 'assessed by consular authorities'. This pack models the formal condition only (P6); the essential condition is an in-person assessment with no corresponding fact, so a satisfied predicate here means eligible to APPLY, never citizenship confirmed
