In the common law, marriage can produce a common domicile for the spouses with the wife taking the domicile of the husband. This rule is derived from the proposition that a dependent wife will follow her husband in all aspects of her life. Although this provides a convenient law which is usually easy to identify (since the requirements for change of domicile depend on demonstrating an intention to reside indefinitely in the state of choice, the domicile of the husband is difficult to change) it may produce a result in which a person is domiciled in one state but the matrimonial home and all other features of the parties' lives may be in a second state. This problem is aggravated by the rules relating to the revival of the domicile of origin when a domicile of choice is abandoned. For example, a husband with a domicile of origin in Japan establishes a domicile of choice in China where he marries a woman with a French domicile. When the relationship breaks down, he abandons his home in China and goes to live in Singapore. Immediately upon his leaving China, his Japanese domicile revives and his wife's domicile also changes to that of Japan even though she might never have set foot in that country. To avoid both the patriarchal implications and potentially unfortunate legal consequences implicit in the domicile of dependence, many states have amended their laws to permit women to retain their domicile of origin upon marriage, or to establish a domicile of choice independently of the husband during the subsistence of the marriage. In cases where the spouses have different domiciles, the choice of law rule must refer to both "lex domicilii".
