A/RES/55/153 Article 6 Legislation on nationality and other connected issues Each State concerned should, without undue delay, enact legislation on nationality and other connected issues arising in relation to the succession of States consistent with the provisions of the present articles. It should take all appropriate measures to ensure that persons concerned will be apprised, within a reasonable time period, of the effect of its legislation on their nationality, of any choices they may have thereunder, as well as of the consequences that the exercise of such choices will have on their status. Article 7 Effective date The attribution of nationality in relation to the succession of States, as well as the acquisition of nationality following the exercise of an option, shall take effect on the date of such succession, if persons concerned would otherwise be stateless during the period between the date of the succession of States and such attribution or acquisition of nationality. Article 8 Persons concerned having their habitual residence in another State 1. A successor State does not have the obligation to attribute its nationality to persons concerned who have their habitual residence in another State and also have the nationality of that or any other State. 2. A successor State shall not attribute its nationality to persons concerned who have their habitual residence in another State against the will of the persons concerned unless they would otherwise become stateless. Article 9 Renunciation of the nationality of another State as a condition for attribution of nationality When a person concerned who is qualified to acquire the nationality of a successor State has the nationality of another State concerned, the former State may make the attribution of its nationality dependent on the renunciation by such person of the nationality of the latter State. However, such requirement shall not be applied in a manner which would result in rendering the person concerned stateless, even if only temporarily. Article 10 Loss of nationality upon the voluntary acquisition of the nationality of another State 1. A predecessor State may provide that persons concerned who, in relation to the succession of States, voluntarily acquire the nationality of a successor State shall lose its nationality. 2. A successor State may provide that persons concerned who, in relation to the succession of States, voluntarily acquire the nationality of another successor State or, as the case may be, retain the nationality of the predecessor State shall lose its nationality acquired in relation to such succession. 4
