20. However, a number of states limit this ground for acquisition to cases where the parent(s) is/are themselves stateless.21 Another limitation is to require that at least one parent has lawful residence in the state involved.22 21. In several states, stateless children born on their territory are entitled to acquire the nationality of their country subject to a certain period of habitual or even lawful residence.23 The way this acquisition takes place can differ from one state to another: the right to register as a national to acquire nationality by declaration of option or acquisition through entitlement to naturalisation. 22. In three states, a stateless child can only acquire the nationality of the country of birth through discretionary naturalisation, although the conditions for this naturalisation are more favourable than in other circumstances.24 Three other states do not provide a more favourable treatment for acquiring nationality to stateless children born on their territory.25 23. Nearly all states provide for the attribution of their nationality to foundlings discovered on their territory. Only in one state is this rule lacking.26 At the same time, state practice reveals a broad range of ages within which this provision applies. Several states limit the granting of nationality to foundlings who are very young (in six states newborns27; in one state under six months28, and in one state under three years29). Several other states do not specify the scope of application of their rules in favour of foundlings, but also apply this ground for the attribution of nationality to older children, including in some cases up to the age of majority. 24. An unconditional ius soli provision does not exist in any member states. However, five states provide for the attribution of nationality to a child of foreigners born on their territory subject to a specific residence condition in respect of a parent.30 Two other states provide – also subject to a specific residence condition – that a person born on their territory can acquire the nationality of their country upon application.31 21.
