Article 1

Nationals of the Contracting Parties who are of full age and who acquire of their own free will, by means of naturalisation, option or recovery, the nationality of another Party shall lose their former nationality. They shall not be authorised to retain their former nationality.

Nationals of the Contracting Parties who are minors and acquire by the same means the nationality of another Party shall also lose their former nationality if, where their national law provides for the loss of nationality in such cases, they have been duly empowered or represented. They shall not be authorised to retain their former nationality.

Minor children, other than those who are or have been married, shall likewise lose their former nationality in the event of the acquisition ipso jure of the nationality of another Contracting Party upon and by reason of the naturalisation or the exercise of an option or the recovery of nationality by their father and mother. Where only one parent loses his former nationality, the law of that Contracting Party whose nationality the minor possessed shall determine from which of his parents he shall derive his nationality. In the latter case, the said law may make the loss of his nationality subject to the prior consent of the other parent or the guardian to his acquiring the new nationality.

However, without prejudice to the provisions of the law of each of the Contracting Parties concerning the recovery of nationality, the Party of which the minor referred to in the foregoing paragraph possessed the nationality may lay down special conditions on which they may recover that nationality of their own free will after attaining their majority.

In so far as concerns the loss of nationality as provided for in the present Article, the age of majority and minority and the conditions of capacity and representation shall be determined by the law of the Contracting Party whose nationality the person concerned possesses.

Notwithstanding the provisions of paragraphs 1 and, where applicable, 2 above, where a national of a Contracting Party acquires the nationality of another Contracting Party on whose territory either he was born and is resident, or has been ordinarily resident for a period of time beginning before the age of 18, each of these Parties may provide that he retains the nationality of origin.

Notwithstanding the provisions of paragraphs 1 and, where applicable, 2 and 5 above, in cases of marriage between nationals of different Contracting Parties, each of these Parties may provide that the spouse, who acquires of his or her own free will the nationality of the other spouse, retains the nationality of origin.

Notwithstanding the provisions of paragraph 2 above, where applicable, when a national of a Contracting Party who is a minor and whose parents are nationals of different Contracting Parties acquires the nationality of one of his parents, each of these Parties may provide that he retains the nationality of origin.
