Article 5

If the law of a Contracting State entails loss of nationality as a consequence of any change in the personal status of a person such as marriage, termination of marriage, legitimation, recognition or adoption, such loss shall be conditional upon possession or acquisition of another nationality.

If, under the law of a Contracting State, a child born out of wedlock loses the nationality of that State in consequence of a recognition of affiliation, he shall be given an opportunity to recover that nationality by written application to the appropriate authority, and the conditions governing such application shall not be more rigorous than those laid down in paragraph 2 of Article 1 of this Convention.
