According to Article 1 of the 52-page Greek Citizenship Code from 2010, a child born in Greece acquires Greek citizenship if:
a) the mother was a Greek citizen during her pregnancy and at the time of the child’s birth; or
b) the father was a Greek citizen at the time of the child’s birth; or
c) both non-Greek parents have been legally living in Greece with the proper residence permits for at least five (5) years at the time of the child’s birth.
A child born in Greece under the above conditions acquires Greek citizenship at birth, unless opting for another foreign citizenship or its citizenship is declared as unknown.
The birth must be recorded in the registry and registered in the family’s oikogeneiaki merida at the time Greek citizenship is being claimed. The latter often becomes an issue when one parent is Greek, the other is not Greek and they were never married or have since divorced, or the non-Greek parent and child have left Greece, without claiming citizenship.
If you’re interested in obtaining Greek citizenship but were not born in Greece to at least one Greek parent, go to “Ways to acquire Greek citizenship” to see if you qualify under other conditions.
