Complete guide to claiming Greek citizenship through your ancestors — eligibility, documents, timeline, costs, and how to file. Reviewed by Ancestra's european union counsel.
Quick Facts
Eligibility
Greece citizenship by descent is governed by Ελληνική ιθαγένεια — descent. Greek citizenship by descent is transmitted through Greek parents, with the 2015 amendment enabling registration of children born abroad. We file through the Greek consulate (with the relevant municipality in Greece) and recover records from the General State Archives in Athens.
Eligibility for Greece citizenship by descent depends on three key factors: (1) the generational distance between you and your Greek ancestor — most Greek programs cover up to grandparent (3rd generation), but some go further; (2) whether the citizenship line was broken by naturalization in another country before the next child's birth in the line; and (3) the specific statute in effect at the time of each birth in the line.
Ancestra's written eligibility opinion addresses all three factors for your specific case, citing the exact statute and consular venue that applies. Our genealogists specialize in recovering the civil registry, parish, and consular records required to establish the unbroken lineage that Greek nationality law requires.
Key constraints & rules
The #1 thing to know
Registration at the Greek municipality (dimos) is the legal mechanism — not a consular application. The consulate facilitates the registration but the municipality issues the final recognition.
Generational limit
No generational limit — any descendant of a Greek citizen can register at the relevant municipality.
Transmission rule
Both parents equally since 1984. Before 1984, paternal only. The 2015 amendment (Law 4332/2015) simplified registration for children born abroad.
Dual citizenship
Permitted — Greece allows dual citizenship.
Language requirement
None for descent path.
Residency requirement
None for descent registration.
Filing authority
Greek municipality (dimos) of the ancestor's origin, via the Greek consulate.
Key statute
Greek Nationality Code (Κώδικας Ελληνικής Ιθαγένειας), Articles 9-14
