ii. Nationality as a consequence of a child-parent family relationship Principle 11. provide that children whose parentage is established by recognition, by court order or similar procedures acquire the nationality of the parent concerned, subject only to a procedure determined by their internal law; 119. More guidance in the explanatory memorandum could prove useful as this has proved to be a complex issue in practice. Principle 12. apply to children their provisions on acquisition of nationality by right of blood if, as a result of a birth conceived through medically assisted reproductive techniques, a child-parent family relationship is established or recognised by law; 120. This principle appears to be relevant for LGBTQ* families. More guidance in the explanatory memorandum may be desirable to take into account social developments. Principle 13. subject the granting of their nationality to children adopted by a national to no other exceptions than those generally applicable to the acquisition of their nationality by right of blood, if as a consequence of the adoption the family relationship between the child and the parent(s) of origin is completely replaced by the family relationship between the child and the adopter(s); Principle 14. facilitate the acquisition of their nationality by children adopted by a national in the case of an adoption in which the family relationship between the child and the parent(s) of origin is not completely replaced by the family relationship between the child and the adopter(s); Principle 15. provide that revocation or annulment of an adoption will not cause the permanent loss of the nationality acquired by the adoption, if the child is lawfully and habitually resident on their territory for a period of more than five years; Principle 16. provide that foreign children lawfully residing on their territory with a view to adoption have the right to file applications for the acquisition of their nationality if the adoption is not finalised. States should not in this case require a period of more than five years of habitual residence on their territory; 121. Owing to the extreme sensitivity on the issue of intercountry adoption, it should be discussed whether principles 13 to 16 should be kept or left out and dealt with in a separate instrument.
