The recognition of paternity in Greece is a fundamental matter of family law, as it establishes the legal relationship between a father and his child, with direct consequences for the child’s surname, inheritance rights, maintenance and parental responsibility. Under Greek law, paternity is not always established automatically. The applicable legal process depends on whether the child was born during a marriage, during a civil partnership or to unmarried parents.
Presumption of Paternity within Marriage
Where a child is born during the mother’s marriage or within 300 days following its dissolution or annulment, the mother’s husband is presumed by law to be the child’s father. This presumption of paternity applies automatically, without any additional act of recognition being required.
A corresponding presumption applies where the child is born during a civil partnership between the mother and a man or within 300 days following the dissolution or annulment of that partnership.
The presumption is rebuttable. It may be challenged before the courts, but only by the persons specifically entitled to do so by law and within the separate statutory time limits applicable to each of them. The presumption is overturned once the relevant judgment becomes irrevocable.
Recognition of Paternity Outside Marriage
The position is different where a child is born to unmarried parents and no presumption arising from a civil partnership applies. In this case, paternity must be formally established through either voluntary recognition of paternity or judicial recognition of paternity.
Voluntary Recognition of Paternity
Voluntary recognition takes place when the father acknowledges the child as his own. The father’s declaration may be made:
- Before a notary.
- By will.
As a general rule, valid voluntary recognition requires the mother’s consent, which must also be given personally before a notary. If the mother has died or lacks legal capacity, recognition may be completed solely through the father’s declaration. If the father has died or lacks legal capacity, Greek law provides, under specific conditions, for recognition by the paternal grandfather or grandmother.
The declarations of recognition and consent must be made personally and cannot be subject to a condition or time limit. Any subsequent revocation is legally ineffective. The consent of an adult child is not a general statutory requirement for voluntary recognition.
A simple declaration before a civil registrar, including one made when the child’s birth is registered, is not an independent legally valid form of voluntary recognition. Registration with the civil registry follows the completion of recognition and constitutes a separate procedural step.
Once recognition has been completed, the child has, in relation to the father and his relatives, the legal status of a child born within marriage, unless otherwise provided by law.
Judicial Recognition of Paternity
Both the mother and the child have an independent right to seek the judicial establishment of paternity. The child’s right exists during minority and is exercised in accordance with the rules governing legal representation. Where the mother refuses to consent to voluntary recognition, the father may also bring proceedings. In the specific circumstances prescribed by law, the paternal grandfather or grandmother may have the same right.
Proceedings are heard under the special procedural rules governing family disputes. A DNA paternity test may constitute decisive evidence. The court may order appropriate medical examinations where it considers them necessary for establishing paternity.
If a party refuses to undergo court-ordered examinations without specific health-related grounds, Greek procedural law provides for a defined evidential consequence: the opposing party’s allegations are deemed proven as regards the existence of biological factors that make paternity scientifically probable or highly probable.
Claims for judicial recognition are subject to strict statutory time limits:
- The mother’s right expires five years after the child’s birth.
- The child’s right expires one year after reaching adulthood.
- The right of the father or his parents expires two years after the mother refuses to give her consent.
Greek law provides for specific exceptions and a different starting point for the applicable period in certain cases, particularly where another man was presumed to be the father during the legally relevant period of conception.
Challenging the Recognition of Paternity
The challenge of voluntary recognition is specifically regulated by law and cannot be brought by any person who merely claims a legal interest. The right belongs primarily to the child and, if the child has died, to the child’s descendants. In the particular cases prescribed by law, it may also belong to certain maternal or paternal ascendants.
The statutory ground for challenging voluntary recognition is that the person declared to be the father is not, in fact, the biological father. The challenge is barred three months after the entitled person learns of the recognition and, in all cases, two years after the recognition. Where the child was a minor at the time of recognition, the child may challenge it within two years after reaching adulthood.
A judicial determination of paternity is not challenged through the same action applicable to voluntary recognition. The relevant judgment is subject to the available procedural remedies and the corresponding rules of civil procedure.
Legal Consequences of Recognition
Whether voluntary or judicial, the recognition of paternity produces significant legal consequences:
- Surname: A child born to unmarried parents initially takes the mother’s surname. Following recognition, the adult child or, if the child is a minor, the parents, either parent or the child’s guardian may, within one year after recognition is completed, add the father’s surname by making a declaration to the civil registrar. If both parents make a joint declaration, they may determine a new surname in accordance with the relevant statutory provisions.
- Inheritance rights: The child acquires full inheritance rights in relation to the father and his relatives, on an equal basis with a child born within marriage.
- Child maintenance: The establishment of legal kinship enables a maintenance claim to be brought against the father. The obligation is determined according to the child’s needs and the financial means of the parents.
- Parental responsibility: Parental responsibility for a minor child born and remaining outside marriage initially belongs to the mother. Following voluntary recognition, or judicial recognition based on an action brought by the father, the father also acquires parental responsibility, which is exercised jointly with the mother. By contrast, where paternity is judicially established despite the father’s opposition, he does not automatically exercise parental responsibility unless the parents agree or the court decides otherwise in the child’s best interests.
Why Legal Guidance Is Important
Paternity cases frequently involve sensitive personal matters, strict statutory time limits and significant family, financial and inheritance interests. The appropriate legal strategy—whether it concerns voluntary recognition, judicial proceedings or a challenge to an existing recognition—requires specialised knowledge of Greek family law and careful handling of the available evidence, particularly genetic evidence.
Frequently Asked Questions (FAQ)
- What is the difference between voluntary and judicial recognition of paternity?
Voluntary recognition is made by the father through a declaration before a notary or by will and, as a general rule, requires the mother’s notarised consent. Judicial recognition is obtained through court proceedings brought by the persons specifically entitled to do so by law.
- Is a DNA test compulsory in judicial paternity proceedings?
It is not automatically ordered in every case, but the court may require it where it considers the examination necessary. A party’s refusal without specific health-related grounds produces the evidential consequences prescribed by the Greek Code of Civil Procedure.
- Can a child seek recognition of paternity after reaching adulthood?
Yes. The child has an independent right to seek the judicial establishment of paternity. This right expires one year after the child reaches adulthood, provided paternity has not already been established. The right also exists during the child’s minority and is exercised in accordance with the rules of legal representation.
- What is required for valid voluntary recognition?
The father must make a declaration before a notary or by will and, as a general rule, the mother must provide her consent before a notary. The declarations must be made personally and cannot be subject to a condition or time limit. The adult child’s consent is not a general statutory requirement.
- Can an existing recognition of paternity be overturned?
Voluntary recognition may be challenged by the persons specifically designated by law, on the ground that the person who made the recognition is not the biological father and within the applicable statutory time limits. A judicial determination of paternity is governed by the rules on procedural remedies and is not challenged through the same procedure.
- What are the consequences of recognition for the child’s inheritance rights?
Following recognition, the child acquires full inheritance rights in relation to the father and his relatives, on an equal basis with a child born within marriage.
- Is there a time limit for bringing judicial paternity proceedings?
Yes. The mother’s right expires five years after the child’s birth, the child’s right expires one year after reaching adulthood, and the right of the father or his parents expires two years after the mother refuses to give her consent. As specific exceptions may apply, the individual circumstances should be assessed promptly.
