Greek Citizenship by Descent: : Eligibility Guide in 2026

Greek citizenship by descent (jus sanguinis) is the right to be recognized as a Greek citizen through your family bloodline. Greek law states that citizenship is inherited and that people born to a Greek parent have the right to it. You can also qualify through a grandparent or great-grandparent, but that depends on the legal proof provided. Greece also has special rules for citizenship by descent that depend on when you were born, your parents’ marital status, and which parent is Greek. Cutoff dates and legal changes also determine your eligibility. 

Therefore, our experts at Global Citizen Solutions, who have helped over 15,000 clients around the world, understand how difficult it is to navigate the nuances of citizenship laws. That is why we recommend working with qualified lawyers and legal professionals. 

Regardless, Global Citizen Solutions is here to inform, and this guide explains in detail the different qualification cases for citizenship by descent in Greece, the application process, documents, and more. 

Greek Citizenship by Descent: Key Takeaways

Greek citizenship by descent allows people with a Greek parent, grandparent, or sometimes great-grandparent to obtain an EU passport if they can prove their family line through official documents.

Applicants must show an unbroken chain of ancestry using birth, marriage, death, and Greek municipal records, and the process takes around 12–24 months for simple cases.

Eligibility depends on your family history, with different rules for those born before or after July 1982 and special conditions for cases involving parents or grandparents.

Greek citizenship gives the right to live, work, and study anywhere in the European Union, along with access to healthcare, education, voting rights, and strong economic opportunities in Greece.

Once approved, applicants can apply for a Greek ID and passport, which allows visa-free or visa-on-arrival travel to many countries worldwide.

Greece allows dual citizenship, meaning you do not need to give up your current nationality when you become a Greek citizen.

Greek citizenship by descent is the process of getting citizenship through your family line (jus sanguinis). You can qualify if you have a Greek parent, grandparent, or great-grandparent, as long as you can prove an unbroken chain of registration in a Greek municipality. There are different rules that apply based on when you were born and which parent is a Greek citizen. Additionally, being born in Greece does not automatically give citizenship, but children of foreign parents can qualify if they attend a Greek school for several years and their parents have lived in the country legally. Special rules depend on the birth date, the parents’ marital status and which parent is Greek. Some of the cutoff dates are 1982 and 1984 for children born before law changes.

Here is who qualifies by descent according to the Greek authorities Ministry of Foreign Affairs, Ministry of Interior and the Greek Citizenship Code. 

1. Born to a Greek parent, and the parent is registered 

If your Greek parent is a citizen, meaning they are registered in a Greek municipal roll, then you, as the child, are considered Greek from birth. This is the simplest case. 

2. Born to a Greek mother and foreign father before 8 May 1984 

You can qualify under this case under the following conditions.  

• You were born of a marriage, and your mother was a Greek citizen at the time of your birth or at the time of the marriage; then you can qualify for citizenship through descent.  
• Your parents were married when you were born. 
• You were born before 8 May 1984. 

What you will need to do is make a formal declaration saying you want Greek citizenship. You do it at a Greek consulate if you live abroad or at the Regional Directorate of Nationality in Greece. You have to show up in person because no one else can sign for you. 

3. Born to a Greek father and foreign mother before mid-July 1982 

This is for people with this specific case at hand. Someone whose father was Greek and whose mother was not, and who was born before about 16-17 July 1982, can apply for citizenship. But again, these conditions must be met:  

1. Your father was Greek. 
2. Your parents were married when you were born. You were born before the cutoff date. 

Similarly, you will also need to make a declaration to a Greek consulate or the Regional Directorate of Nationality.  

4. Born out of wedlock to a Greek father 

If you were born out of wedlock to a Greek father and a foreign mother, then you can get Greek citizenship only once the father has officially recognized you as his child. There are conditions to this case too.  

1. Your father needs to legally acknowledge you. This can be done in Greece or in another country.  
2. Your father has to be properly registered as a Greek citizen in a Greek municipality.  
3. You will become a Greek citizen from the date your father legally recognizes you, not from birth.  

Age matters: 

• Over 18: You apply through the consulate’s citizenship-determination process. 
• Under 18: The consulate sends you to the birth-registration process instead. 

5. Child of a Greek mother who lost citizenship through a foreign father 

In this case, you can qualify for Greek citizenship if you are someone who was considered Greek through a Greek mother before 8 May 1984, but lost that citizenship because a foreign father was legally recognized, which then gave you a foreign nationality.  

You can apply for Greek citizenship under these requirements:  

1. You were born before 8 May 1984. 
2. Your mother was Greek, and you were registered in a Greek municipal roll. 
3. You lost Greek citizenship on the date your foreign father legitimized or recognized you. 
4. You have documents proving that legal recognition. 

You will also need to declare that you want your Greek citizenship back at a consulate or the Regional Directorate. Your minor, unmarried children will also inherit Greek nationality. 

Greek citizenship by descent offers several benefits, including the chance to live in Greece and enjoy its beautiful coastlines and countryside. Below are the top 5 advantages of acquiring Greek citizenship.

1. Economic opportunities: Holding Greek citizenship allows you to enjoy several economic opportunities in the country, such as opening a business, making profitable investments, and working within the European Union.
2. Access to healthcare and education: Greece has a strong public system that includes healthcare, education, political rights, and a rich culture. Greek citizenship gives you full access to all of these services and benefits
3. Freedom of movement within the European Union: Greek citizenship grants the invaluable privilege of European Union membership, with visa-free travel to all member states and the ability to live, work, and study in any European Union country.
4. Voting rights: Greek citizenship allows full voting rights in national, local, and European Parliament elections. Citizens can also run for public office and actively participate in the political process at various levels.
5. Greek passport: If you obtain Greek citizenship, you are eligible to apply for a Greek passport, which ranks 42nd on the Global Citizen Solutions Global Passport Index. This strong passport allows visa-free travel to numerous countries, offering great mobility and opportunities.

Greece has a standard for how these documents must be submitted. All non-Greek documents should have an Apostille stamp and be officially translated into Greek by an approved translator. If your ancestor’s name changed over time, you are also required to submit proof or a “same person” affidavit to confirm it is the same person.

• Valid passport: Full copy of all pages.
  Your birth certificate: Must show both parents’ names.
• Marriage certificate: If you are married or have changed your name.
• Police clearance: Issued in the last 6 months, but only for applicants over 18.
• Passport photos: 2–4 recent photos.
• Parent and grandparent documents: Their birth, marriage, religious or civil, and death certificates, if applicable.
• Greek registration documents (very important):
  • Certificate of Registration from a Greek municipality
  • Male Registry Certificate (for male ancestors)
  • Family Status Certificate (shows family details in Greece)

Here’s a step-by-step guide on how to start Greek citizenship by descent application:

Step 1: Locate your Greek ancestor

The first step is to go the Consulate of your residence, and explain the relationship between you and your Greek parents or ancestor. Provide the consulate with all the details they need and find out if any documents can be retrieved through a search on the search the National Municipal Registry. If not, ask what exactly you need for your specific case and if assistance is available. Unfortunately, the Consulate may not be able to give all the records you need. But it is a starting point.

Step 2: Gather your documents

The proof of our citizenship lies in your legal documents. Collect all birth and marriage records for each generation. Remember that for every generation, you need long-form, unabridged certificates, and all non-Greek documents must have an Apostille and be translated.

Step 3: Book a consulate appointment and possible interview

Schedule a meeting at your local Greek Consulate. You will pay a fee a standard government fee. If you are applying through a grandparent, you will have a brief, informal interview to confirm your ties to Greece and your family history.

Step 4: Wait for approval

 Your application will be reviewed by the Greek authorities. This is the longest phase of the process. Parent-based applications can take six to be shorter but even then there is no specific timeline. The grandparent-based claims can take years because records are manually verified in local Greek archives.

Step 5: Register in Greece:

After the long wait, the Ministry of Interior approves the application and issues a decision of citizenship. Your birth is then recorded in the Municipal Roll.

Step 6: Apply for ID and passport

After registration, you can apply for your Greek ID card and Greek passport. However, the passport application is separate process from having your citizenship approved.

Yes, Greece does allow dual citizenship. Therefore, anyone obtaining Greek dual citizenship does not need to renounce their existing citizenship when they become a Greek citizen.  The inverse is true for existing Greek citizens taking on a second citizenship. However, it is important to also make sure that your country of origin also allows dual citizenship.
