“In addition to the physical presence of the child in the territory of a [member] state, other factors must be chosen which are capable of showing that presence is not in any way temporary or intermittent…”; c) Factors of relevance, as set out in Proceedings brought by HR, at para 43, and reflected in many other domestic cases, include: “the duration, regularity, conditions and reasons for the child’s stay in the territory of the different [member] states concerned, the places and conditions of the child’s attendance at school, and the family and social relationships of the child in those member states”; d) The intentions of the parents are also a relevant factor and there is no “rule” that one parent cannot unilaterally change the habitual residence of a child; e) As set out In re R, at para 16, it is “the stability of the residence that is important, not whether it is of permanent character” but there “is no requirement that the child should have been resident in the country in question for a particular period of time” because habitual residence can be acquired quickly; f) The “degree of integration of the child into a social and family environment in the country in question” is relevant, In re R, at para.17. It is clear that “full integration” is not required, but only a degree sufficient to support the conclusion, when added to the other relevant factors, that the child is habitually resident in the relevant state; g) The relevant factors will reflect the age of the child. Accordingly, “[the] social and family environment of an infant or young child is shared with those (whether parents or others) on whom he is dependent. Hence it is necessary to assess the integration of that person or persons in the social and family environment of the country concerned.” h) The court is considering the connections between the child and the country or countries concerned. This is a comparative analysis: “What is important is that the judge demonstrates sufficiently that he or she has had in mind the factors in the old and new lives of the child, and the family, which might have a bearing on this particular child’s habitual residence.”
