A domicile of origin is one assigned to a child at the time of its birth. The domicile of origin of a legitimate child is the domicile of his father at the time of his birth, of an illegitimate child the domicile of his mother, and of a foundling the place where he is found. Domicile of origin is, strictly speaking, one kind of constructive domicile. Greater importance is attached to domiciles of origin than to other species of domicile. It requires more evidence to prove that a domicile of origin has been given up, and such a domicile after being lost may be more easily re-acquired, at least in the case of national domiciles.
