Argument for Appellants. Stat. 1783, c. 24, "adopting the construction which has been given to it by the Supreme Court." See brief of counsel for appellee in Wilson v. Fosket, cited ante. Under this last statute Wilson v. Fosket was decided in 1843. That case, without overruling the prior cases in Massachusetts under the statute of 1783, or intimating a doubt of their correctness, decided that the commissioners "had builded better than they knew," and that under the new statute parol evidence, including evidence of the parol declarations of the testator, was admissible to show that the testator intended to omit to provide for his child. That case has ever since been followed in Massachusetts under the same statute. Iowa adopted the Massachusetts statute, last cited, and adopted with it the judicial construction placed thereon by the Massachusetts courts. Lorieux v. Keller, 5 Iowa, 196; S. C. 68 Am. Dec. 696. We submit that unless the Massachusetts cases under the new statute find their warrant for the admission of extrinsic evidence in the words, "and not occasioned by any mistake or accident," they are opposed to both principle and the weight of authority. It is difficult to conceive how a mistake or accident can be shown except by extrinsic evidence, and such mistake or accident as will permit the child to inherit has been held in Massachusetts to be perfectly consistent with an intentional omission of the child's name from the will. Ramsdill v. Wentworth, 101 Mass. 125. In Missouri the statute is substantially the same as the Massachusetts statute of 1783, and has uniformly received the same construction, viz.: that to disinherit a child it is not necessary that he should be named or provided for in the will of the parent, if the omission to do so appears to be intentional; but that such intention can only be proved by intrinsic evidence. Bradley v. Bradley, 24 Missouri, 311; Burch v. Brown, 46 Missouri, 441; Pounds v. Dale, 48 Missouri, 270; Wetherall v. Harris, 51 Missouri, 65. See, also, Chace v. Chace, 6 R. I. 407 ; S. C. 78 Am. Dec. 446. The Utah statute in question is precisely similar, it seems to us, to the Massachusetts statute of 1783 and to the Missouri statute as they were judicially construed. Argument for Appellants. In California in 1868, in the case of Estate of Garraud, 35 California, 336, section 17 of the Stat. of Wills of that State, of which (694) sec. 10, Comp. Laws of Utah, 1876, is an exact copy, first received a judicial construction by the Supreme Court. In that case it was held that the intention of the testator to omit to provide for his children can only be gathered from the face of the will; that it can only be proved by evidence competent to prove any other testamentary intention, and that evidence of the acts and declarations of the testator is inadmissible to prove such intention. Suppose at the time of the actual execution of the will, the testator unintentionally omits to provide for his children, but that afterwards he changes his mind and declares his intention not to provide for them, is the will ambulatory in the meantime? and where are such changes to stop? If there be any doubt as to the true construction of the statute in question, it would be settled by the consideration, that in adopting the California statute, we adopted its received construction in California, which must be considered as accompanying the statute to this Territory, and forming an integral part of it. Cathcart v. Robinson, 5 Pet. 264; Bemis v. Becker, 1 Kansas, 226. The leading case of Estate of Garraud, 35 California, 336, was decided in 1868. In the case of Estate of Utz, 43 California, 200, decided in 1872, and in Pearson v. Pearson, 46 California, 609, decided in 1873, the leading case was admitted counsel to be controlling in California, and its authority has never been questioned in that State. In 1876, the legislature of Utah Territory enacted a statute of wills, seven sections of which were literally copied from the California act, as it was when the Estate of Garraud was decided. See sections, 6-12 inclusive, Compiled Laws of Utah, p. 271. One of these sections, section 10, is the one invoked by appellants in this case. It is to be presumed, then, that the legislature of Utah Territory was familiar with the judicial construction of the California statute placed thereon by the highest court of that State, and that they intended to adopt that construction when they adopted the statute. Opinion of the Court. Although evidence of all the circumstances which surrounded the author of a written instrument will be received for the purpose of ascertaining his intentions, yet those intentions. must ultimately be determined by the language of the instrument. No proof, however conclusive in its nature, can be admitted with the view of setting up an intention inconsistent with the known meaning of the writing itself. For the duty of the court in all these cases is to ascertain, not what the parties may have really intended, as distinguished from what their words express, but simply what is the meaning of the words they have used. It is merely a duty of interpretation, and evidence of surrounding circumstances cannot change the legal effect of clear and unambiguous words. Reynolds v. Fire Ins. Co., 47 N. Y. 597, 606; Partridge v. Ins. Co., 15 Wall. 573; Maryland v. Railroad Co., 22 Wall. 105; Kurtz v. Hibner, 55 Illinois, 514; Waldron v. Waldron, 45 Michigan, 350. There is no pretence made in this case that the language of the will is not clear and unambiguous. The uniform language of the authorities is to the effect that no intention to omit to provide for the children appears by reason of the absolute devise to the appellee. C. B. & Q. Railroad v. Wasserman, 22 Fed. Rep. 874; Pounds v. Dale, 48 Missouri, 270; Ramsdill v. Wentworth, 106 Mass. 320; Bush v. Lindsay, 44 California, 121. Mr. Benjamin Sheeks and Mr. Joseph L. Rawlins for appellee. MR. CHIEF JUSTICE FULLER, after stating the case as above, delivered the opinion of the court. Accepting the finding of fact that the testator intentionally excluded his children from any share of the property disposed of by the will, respecting which, upon this record, there could be no doubt, the only question in the case is as to whether the court erred in admitting extrinsic evidence to establish that the omission to provide for the children was intentional. The solution of this question depends upon the proper construction of the statutes of Utah bearing upon the subject. Opinion of the Court. Under those statutes a will or codicil to "pass the estate of the devisor" must be in writing; and by section one of "An Act relative to the Estates of Decedents," approved February 18, 1876, which is section 685 of the Compiled Statutes of Utah of that year, "every devise purporting to convey all the real estate of the testator" carried that subsequently acquired, "unless it shall clearly appear by his or her will that he or she intended otherwise." Sections 9, 10 and 12 are as follows: (693) "SEC. 9. When any child shall have been born, after the making of its parent's will, and no provision shall have been made for him or her therein, such child shall have the same share in the estate of the testator, as if the testator had died intestate; and the share of such child shall be assigned as provided by law, in case of intestate estates, unless it shall be apparent from the will that it was the intention of the testator that no provision should be made for such child. (694) "SEC. 10. When any testator shall omit to provide in his or her will for any of his or her children or for the issue of any deceased child, unless it shall appear that such omission was intentional, such child, or the issue of such child, shall have the same share in the estate of the testator as if he or she had died intestate, to be assigned as provided in the preceding section." (696) "SEC. 12. If such child, or children, or their descendants, so unprovided for, shall have had an equal proportion of the testator's estate bestowed on them in the testator's lifetime, by way of advancement, they shall take nothing in virtue of the provisions of the three preceding sections." Compiled Laws of Utah, 1876, 262, c. 2, tit. 14. Section 19 provides that, in case of intestacy, if the decedent left a husband or a wife and more than one child, the estate of the decedent shall go, one-fourth to the surviving husband or wife for life and the remainder with the other three-fourths to the children. It will be seen that section 12 applies to advancements during the lifetime of the testator, and section 9 to a child born after the execution of the will, no provision having been made VOL. CXXXIII-15 Opinion of the Court. for it therein. The child is to take its share as provided by law in case of intestacy, "unless it shall be apparent from the will that it was the intention of the testator that no provision should be made for such child." And section 10 relates to children in being, or the issue of any deceased child, at the time of the execution of the will, who are to take as in case of intestacy, "unless it shall appear that such omission was intentional." As to a child born after the making of the will, the intention to omit must be apparent from the will; as to children in being when the will is made, the statute does not say how it shall appear that the omission was intentional. But it is insisted on behalf of appellants that such intention is required in the latter case also to appear from the will, and cannot be shown by evidence aliunde. The source of the statute under consideration was undoubtedly that of Massachusetts upon the same subject, though it is said that this particular statute was taken from a similar one in California. The first and second sections of an act of the Province of Massachusetts, passed in the year 1700, (12 Wm. 3,) with their preambles, read as follows: "Forasmuch as it often happens that children are not borne till after the death of their fathers, and also have no provision made for them in their wills, "Be it therefore enacted, etc., That as often as any child shall happen to be borne after the death of the father, without having any provision made in his will, every such posthumous child shall have right and interest in the estate of his or her father, in like manner as if he had died intestate, and the same shall accordingly be assigned and set out as the law directs for the distribution of the estates of intestates. "And whereas, through the anguish of the diseased [deceased] testator, or through his solicitous intention though in health, or through the oversight of the scribe, some of the testator's children are omitted and not mentioned in the will, many children also being borne after the makeing of the will, thô in the lifetime of their parents, "Be it therefore enacted, etc., That any child or children not |
