Testamentary capacity is generally governed by the law of the testator's domicile at the time of his death, the form of the instrument in most countries either by the law of his domicile or the law of the place where the will was made, at his option. The old rule of English law was to allow the former alternative only. The law was altered for the United Kingdom in 1861 by the Wills Act 1861 (known as Lord Kingsdown's Act), by which a will made out of the United Kingdom by a British subject is, as far as regards personal estate, good if made according to the forms required by the law of the place where it was made, or by the law of the testator's domicile at the time of making it, or by the law of the place of his domicile of origin. Subsequent change of domicile does not avoid such a will. Another act passed on the same day, the Domicile Act 1861, enacted that by convention with any foreign government foreign domicile with regard to wills could not be acquired by a testator without a year's residence and a written declaration of intention to become domiciled. By the same act foreign consuls may by convention have certain authority over the wills and property of subjects of foreign states dying in England.
