The member States of the Council of Europe, signatory hereto,
Considering that the aim of the Council of Europe is to achieve a greater unity between its members, in particular by the adoption of common rules in the field of law;
Noting that in a great number of member States efforts have been, or are being, made to improve the legal status of children born out of wedlock by reducing the differences between their legal status and that of children born in wedlock which are to the legal or social disadvantage of the former;
Recognising that wide disparities in the laws of member States in this field still exist;
Believing that the situation of children born out of wedlock should be improved and that the formulation of certain common rules concerning their legal status would assist this objective and at the same time would contribute to a harmonisation of the laws of the member States in this field;
Considering however that it is necessary to allow progressive stages for those States which consider themselves unable to adopt immediately certain rules of this Convention,
Have agreed as follows:

Article 1

Each Contracting Party undertakes to ensure the conformity of its law with the provisions of this Convention and to notify the Secretary General of the Council of Europe of the measures taken for that purpose.

Article 2

Maternal affiliation of every child born out of wedlock shall be based solely on the fact of the birth of the child.

Article 3

Paternal affiliation of every child born out of wedlock may be evidenced or established by voluntary recognition or by judicial decision.

Article 4

The voluntary recognition of paternity may not be opposed or contested insofar as the internal law provides for these procedures unless the person seeking to recognise or having recognised the child is not the biological father.

Article 5

In actions relating to paternal affiliation scientific evidence which may help to establish or disprove paternity shall be admissible.

Article 6

1. The father and mother of a child born out of wedlock shall have the same obligation to maintain the child as if it were born in wedlock.
2. Where a legal obligation to maintain a child born in wedlock falls on certain members of the family of the father or mother, this obligation shall also apply for the benefit of a child born out of wedlock.

Article 7

1. Where the affiliation of a child born out of wedlock has been established as regards both parents, parental authority may not be attributed automatically to the father alone.
2. There shall be power to transfer parental authority; cases of transfer shall be governed by the internal law.

Article 8

Where the father or mother of a child born out of wedlock does not have parental authority over or the custody of the child, that parent may obtain a right of access to the child in appropriate cases.

Article 9

A child born out of wedlock shall have the same right of succession in the estate of its father and its mother and of a member of its father's or mother's family, as if it had been born in wedlock.

Article 10

The marriage between the father and mother of a child born out of wedlock shall confer on the child the legal status of a child born in wedlock.

Article 11

1. This Convention shall be open to signature by the member States of the Council of Europe. It shall be subject to ratification, acceptance or approval. Instruments of ratification, acceptance or approval shall be deposited with the Secretary General of the Council of Europe.
2. This Convention shall enter into force three months after the date of the deposit of the third instrument of ratification, acceptance or approval.
3. In respect of a signatory State ratifying, accepting or approving subsequently, the Convention shall come into force three months after the date of the deposit of its instrument of ratification, acceptance or approval.

Article 12

1. After the entry into force of this Convention, the Committee of Ministers of the Council of Europe may invite any non-member State to accede to this Convention.
2. Such accession shall be effected by depositing with the Secretary General of the Council of Europe an instrument of accession which shall take effect three months after the date of its deposit.

Article 13

1. Any State may, at the time of signature, or when depositing its instrument of ratification, acceptance, approval or accession, specify the territory or territories to which this Convention shall apply.
2. Any State may, when depositing its instrument of ratification, acceptance, approval or accession or at any later date, by declaration addressed to the Secretary General of the Council of Europe, extend this Convention to any other territory or territories specified in the declaration and for whose international relations it is responsible or on whose behalf it is authorised to give undertakings.
3. Any declaration made in pursuance of the preceding paragraph may, in respect of any territory mentioned in such declaration, be withdrawn according to the procedure laid down in Article 15 of this Convention.

Article 14

1. Any State may, at the time of signature, or when depositing its instrument of ratification, acceptance, approval or accession or when making a declaration in accordance with paragraph 2 of Article 13 of this Convention, make not more than three reservations in respect of the provisions of Articles 2 to 10 of the Convention.
   Reservations of a general nature shall not be permitted; each reservation may not affect more than one provision.
2. A reservation shall be valid for five years from the entry into force of this Convention for the Contracting Party concerned. It may be renewed for successive periods of five years by means of a declaration addressed to the Secretary General of the Council of Europe before the expiration of each period.
3. Any Contracting Party may wholly or partly withdraw a reservation it has made in accordance with the foregoing paragraphs by means of a declaration addressed to the Secretary General of the Council of Europe, which shall become effective as from the date of its receipt.

Article 15

1. Any Contracting Party may, insofar as it is concerned, denounce this Convention by means of a notification addressed to the Secretary General of the Council of Europe.
2. Such denunciation shall take effect six months after the date of receipt by the Secretary General of such notification.
