Colt, J.
In the will of their father, provision is omitted to be made for the petitioners, and they are entitled, under the statute, to such share of his real estate as they would have taken if he had died intestate, unless it appears that the omission was intentional, and not occasioned by accident or mistake. Gen. Sts. c. 92, § 25. The omission may be shown to be intentional, and not the result of accident or mistake, both by the terms of the will and by extrinsic paroi evidence. Wilson v. Fosket, 6 Met. 400. There is nothing in the will, except the fact of the omission, which indicates a purpose not to provide for them.
The respondents rely upon evidence tending to show that, in making his will, the testator understood that he had provided tor his children by giving to his wife only a life estate in his property, and that after her death it would be equally divided between them. The will in terms gives all his estate to his wife, who was the mother of these petitioners, to be held by her and her heirs forever, to her and their sole and separate use. It *127is not quite "clear, upon these exceptions, whether the evidence was that he understood that the words of the will made provision for his children by giving them the remainder, subject to a life estate in the wife, or only that they would take by law a portion as intestate or undevised estate, either free from or subject to the life interest. Nor is it material, for a majority of the court are of opinion that, in either aspect, the evidence does not show such intentional omission to provide for them, free from accident or mistake, as will deprive them of their share of his estate under the statute. It shows that the omission was caused by a mistake as to the legal effect of the will and its provisions. It proves that he intended his children should share in his estate, and acted under the mistaken idea, either that the will would carry out his intention, or that it would not have the effect to deprive them of every portion of his property. It does not disclose an intention not to provide for them. If the omission is treated as an intentional act, yet it was occasioned by a mistake, and is not within the excepting clause of the statute. The nature of the mistake is not material. There is no distinction between mistake of fact and mistake of law in this regard. If the testator, in ignorance or mistake of law, supposed that he had provided for them by the terms used in his will, then his failure to name them, or to use apt words of devise to them, cannot, within the meaning of the statute, be regarded as an intentional omission. If he purposely omitted them, thinking that the will left any part of the estate undevised, which would go to them, he was acting under mistake.
The operation of the statute is peculiar, but there is no violation under it of the rules of evidence. The only issue is, whether provision was omitted in the will by design, and with-v ut mistake or accident. Parol evidence is admitted, although the result may change or modify the disposition of the testator’s estate. The will is used to show that there is no legacy under it; and however the issue may be established, there is no conflict with its terms. Bancroft v. Ives, 3 Gray, 367. Converse v. Wales, 4 Allen, 512. Lorings v. Marsh, 6 Wallace, 337.
The successive statutes upon this subject are substantial reen* *128actments of the early provincial statute of 12 Wm. III. c. 4 , Anc. Chart. 351; 1 Prov. Laws, (State ed.) 429, 430. The later enactments add the force of positive law to the judicial construction which had long been put upon that act. The preamble and other provisions of it have always had a just influence upon the construction of the existing law. It provides for posthumous children; for children who have no legacy given them, and who have not had an equal portion of the father’s estate in his lifetime ; and for widows who were married after the making of the will. It recites in the preamble, the anguish of the testator, or his solicitous intention, though in health, or the oversight of the scribe, as among the causes of the omission in the will; many children also being born after the making of the will, and in the lifetime of their parents. The clear intent of the statute is, that none of these shall be excluded from a share in the estate, on the ground that they are left out of the will, unless it is made to appear, as to children, that it was the intelligent, intentional act of the testator. Mistake and ignorance on his part, and the oversight of the scribe, are alike grounds of relief.
Exceptions sustained.
