In the United States some states have adopted the narrow policy of enacting by statute the old common law rule, and providing that no will is valid unless made in the form required by the law of the state of the testator's domicile. The capacity of the testator, revocation and construction of a will, are governed by the law of the domicile of the testator at the time of his death—except in cases affected by Lord Kingsdown's Act, as he must be supposed to have used language in consonance with that law, unless indeed he express himself in technical language of another country. A good instance is Groos' Case (1904), Prob. 269, where it was held that the will of a Dutch woman (at the time of her death domiciled in England) duly made in Holland was not revoked by her marriage, that being no ground of revocation by the law of Holland.
