“A will made by a person under no testamentary incapacity and duly executed or formally valid may nevertheless be invalid, or wholly or partly inoperative, because it contains provisions to which the law will not give effect…… Such invalidity, arising from the nature of the bequest, is termed material or essential invalidity, and whether a will is or is not void wholly or in part on account of such invalidity depends upon the law of the country where the testator is domiciled at the date of his death.”
“It is well settled that the material or essential validity of a will of movables or of any particular gift of movables contained therein is governed by the law of the testator’s domicile at the date of his death. That law determines such questions as whether the testator is bound to leave a certain proportion of his estate to his children or widow, whether legacies to charities are valid, to what extent gifts are invalid as infringing the rule against perpetuities or accumulations, whether substitutionary gifts are valid, whether gifts to attesting witnesses are valid, and so on.”
“We are dealing with a will: and, whilst I would agree that the construction of a will depends on the intention of the testator, I would say that in no other respect does his intention determine the law applicable to it. Let me take first the case where there is a disposition of movable property by will. There is no doubt that the proper law regulating the disposition of movables is the law of the domicile of the testator at the time of his death. In the leading case on this subject Lord Carnworth used the word “regulate” in this very connection. When a person dies domiciled abroad, he said, “in every case the succession to personal property will be regulated not according to the law of this country but to that of his domicile”: see Enohin v Wylie. There is perhaps an exception in regard to the construction of his will: for if a question arises as to the interpretation of the will and it should appear that the testator has changed his domicile between making his will and his death, his will may fall to be construed according to the law of his domicile at the time he made it: though in all other respects it would be governed by the law of his domicile at the date of his death.”
“In the case of immovables it is lex situs (as the House of Lords held) and in the case of movables it is, in my judgment, the lex domicilii, from which the validity of the disposition stems. As Mr Foster conceded, if the law of South Africa had forbidden the disposition with which I am concerned, it could not have taken effect.”
