With the purely local phases of the law governing the relation of husband and wife, Conflict of Laws has no concern. Nor do we deal with Public International Law problems, such as the question of expatriation by marriage. We are concerned with two questions: first, what law governs the creation of the marriage relation; and second, the recognition and protection to be given the relation and incidents arising therefrom, under the law of states other than that in which the relationship was created.
