aof the ECN. This repetition of an existing provision proves to be necessary because several member states, including member states which have ratified the ECN, do not completely implement the rules enshrined in that provision of the convention. As already indicated in the explanatory remarks on principle 1, several states provide that a child whose parentage is established by recognition, court order or similar procedures does not acquire
ex legethe nationality of his or her parent, but only if a certain procedure is followed. During that procedure it can, for example, be established whether a valid recognition took place or whether a foreign decision on parentage can be recognised. However, some states require additional conditions to be fulfilled. These additional conditions, for example, based on the assumption that a child whose family relationships with her or his father is not based on marriage will be less likely to develop genuine and effective ties with the state of nationality of this father or based on the desire to avoid fake recognition, are not in line with ECN. For instance, requiring that the child concerned has her or his habitual residence in the state before she or he can be registered as a national or requiring proof with regard to the biological evidence of the recognition is not in conformity with the provisions of the ECN’.
