Greek Citizenship by Descent
Greek citizenship by descent allows those with Greek parents or grandparents to claim citizenship. If a parent was a Greek citizen at your birth, you may be entitled to citizenship. Greek origin (ethnic Greeks with grandparents from Greece) have a special naturalization path with reduced requirements.

Who qualifies for Greek citizenship by descent
Greece's citizenship-by-descent system primarily operates through the municipal registry (dimotologio). If your parent was registered as a Greek citizen, you are entitled to citizenship by birth. Those with Greek grandparents or great-grandparents may qualify as ethnic Greeks (omogenis) for a simplified naturalization process that waives residency requirements. The key is documenting your ancestor's presence in Greek municipal records.

It all runs through the dimotologio
Greek citizenship by descent is built around the municipal register, the dimotologio. If your Greek ancestor was inscribed in a municipality's register as a Greek citizen, that record is the foundation of your claim; without it, there is often no claim to build. Under Article 1 of the Citizenship Code (Law 3284/2004), a child of a Greek citizen — mother or father — is Greek by descent, and the dimotologio is the authoritative proof of who held that status.
The first practical step in almost every Greek case is locating the ancestor's municipal registration — which village or town, which family record. Greek Orthodox baptism records and old family (oikogeneiaki) records held by the municipality are the usual sources. People frequently confuse being registered in a municipality with holding citizenship; the registration is the evidence, and getting the certified extract is what unlocks the consular process.
Ethnic Greeks (omogenis): a separate, discretionary route
If your Greek connection runs through a grandparent or further back, you may qualify as omogenis — of Greek origin — for a simplified naturalisation under the Citizenship Code that waives the ordinary residency requirement. It is decided case by case: you must show Greek origin and Greek national consciousness, so outcomes are harder to predict than a straightforward descent recognition. This is separate from the pure descent recognition under Article 1 and is used heavily by the diaspora in the United States, Australia, Germany, and the UK.
Which track you use depends on whether your parent was themselves registered as a Greek citizen (descent recognition) or whether you are relying on more distant Greek ancestry (omogenis naturalisation). The document set overlaps heavily, but the legal basis and processing differ.
Transliteration is a real obstacle
Greek names moving between the Greek and Latin alphabets rarely land the same way twice. The same surname can appear three different ways across an ancestor's Greek record, a ship manifest, and a naturalisation certificate. Greek authorities need the chain of names to reconcile, so resolving transliteration discrepancies — often with an affidavit or a supporting record — is part of nearly every file.
Wartime losses compound this. Civil and municipal records destroyed during the Second World War or the Greek Civil War sometimes force reliance on church records or secondary evidence, and record-keeping practices varied by region.
Timeline, cost, and dual citizenship
Recognition for a child of a Greek citizen typically takes 6 to 12 months. Omogenis naturalisation runs 12 to 24 months depending on documentation and the consulate. A straightforward parent-descent claim usually costs €300 to €700: modest consular fees, authenticated municipal record copies, apostilles, and certified Greek translations at €60 to €120 per document.
Greece permits dual citizenship. Greek citizens who acquire another nationality do not automatically lose Greek citizenship, and new citizens are not required to renounce their existing passport.

Greek citizenship FAQ
What is the dimotologio and why does it matter?
It is the Greek municipal register. Your Greek ancestor's inscription in a municipality's register as a Greek citizen is the documentary foundation of a descent claim. Locating that registration — and obtaining a certified extract — is the first step in almost every Greek case.
Can I claim Greek citizenship through a grandparent?
Possibly, as an ethnic Greek (omogenis): a simplified, discretionary naturalisation under the Citizenship Code that waives the residency requirement but requires you to show Greek origin and national consciousness. If your parent was themselves a registered Greek citizen, you instead use descent recognition under Article 1 of the Citizenship Code.
My family's surname is spelled differently on different documents — is that a problem?
It is a common one. Names moving between the Greek and Latin alphabets are rarely consistent. Greek authorities need the chain of names to reconcile, so you will usually need an affidavit or supporting record to tie the variants together.
Does Greece allow dual citizenship?
Yes. Greek citizens who acquire another nationality do not automatically lose Greek citizenship, and new citizens are not required to renounce their existing one.
How long does recognition take?
Around 6 to 12 months for a child of a Greek citizen; 12 to 24 months for omogenis naturalisation through a grandparent or more distant ancestor.
Greek nationality law
Greek citizenship is governed by the Greek Citizenship Code (Law 3284/2004, as amended by Law 4332/2015). Article 1 provides for citizenship by descent (jus sanguinis) through a Greek-citizen parent. Registration in a municipal register (dimotologio) is how that citizenship is recorded and proved in practice. Naturalization of people of Greek origin (omogeneis) living abroad is a separate, discretionary procedure under the Code.
Dual citizenship in Greece
Greece permits dual citizenship. Greek citizens who acquire another nationality do not automatically lose Greek nationality, and foreign nationals who naturalise as Greek are not required to renounce prior citizenship. The Greek diaspora — particularly in the United States, Australia, Germany, and the United Kingdom — widely holds dual nationality.
Greek application costs
Citizenship recognition or registration at a Greek consulate: €30–€100 in fees. Authenticated copies of Greek municipal records: €3–€10 per page. Apostilles in your home country: €15–€40 per document. Certified translations into Greek: €60–€120 per document. Total for a straightforward parent-descent claim: €300–€700.

Michael Soucek— Claimed Hungarian citizenship by descent firsthand
Founder & Researcher, Heritage Passport Finder
I built Heritage Passport Finder after going through the process of claiming Hungarian citizenship by descent myself. Tracing my family's records and working out what actually qualified turned into a genuine obsession with how citizenship-by-descent law works across Europe, so I started gathering what I learned in one place. I'm not a lawyer, and I don't treat these guides as the final word — citizenship law changes constantly and differs by country, so every page points to official sources and I recommend confirming your own case with the relevant consulate or an immigration attorney. What I can offer is a clear map of the landscape, drawn from official sources and the experience of someone who has actually been through it.
