delivered the opinion of the court:
This is a bill in chancery filed by Francis D., Leslie and Leon- Roche, minors, by their next friend, James S. Roche, in the circuit court of Alexander county, against *253Homer Atherton and Fannie E. Jones, to reform a certain deed bearing date March 21, 1882, executed by Francis D. Atherton and Martha E., his wife, conveying ninety-nine acres of land off of the south side of lot 3, claim 529, survey 527, in Alexander county, Illinois, to Margaret E. and Byron J. Atherton, “to them and their bodily heirs forever,” so that it would operate to vest the remainder in fee in said lands in all the heirs of said Margaret E., deceased, and that partition of the land described therein be made according to the rights and interests of the parties after such reformation of the deed should have been made. The defendant Fannie E. Jones entered her appearance and filed an answer admitting the allegations of the bill. The defendant Homer Atherton, who was duly served with summons, being a minor, a guardian ad litem was appointed for him. The answer of the guardian ad litem having been filed and a replication thereto, the cause was referred to the master in chancery to take and report proofs and his findings and conclusions of law. The proofs having been taken, the report of the master in chancery filed and exceptions overruled thereto, a decree was entered reforming said deed and appointing commissioners to make partition of said land equally between the complainants and defendants, on the basis that said Francis D. Boche, Leslie Boche, Leon Roche, Homer Atherton and Fannie E. Jones were each the owners in fee simple of the undivided one-fifth part of said land, from which decree Homer Atherton has prosecuted an appeal to this court.
The master in chancery found that Francis D. Atherton, the grandfather of the complainants and defendants, (now deceased,) was on the 21st day of March, 1882, the owner in fee simple of said land; that on said day, for the expressed consideration of ten dollars, he, together with his wife, Martha E. Atherton, conveyed said land to his daughter, Margaret E. Atherton, and Byron J. Atherton, her husband, and their bodily heirs; that said *254Byron J. Atherton, the husband of Margaret E. Atherton, was not of kin or otherwise related to said Francis D. Atherton; that in said deed the party of the second part is described as “Margaret E. and Byron J. Atherton,” and the granting clause therein is “to them and their bodily heirs forever,” and the haibendum clause recites that the said land is to be held to the only proper use, benefit and behoof of “the said party of the second part and their bodily heirs forever,” and the relinquishment of homestead in the said deed is unto the said party of the second part and “their bodily heirs;” that the said Margaret E. Atherton was married three times, the first marriage being to David R. Peeler in the year 1878, by which marriage she had one child, a daughter, now Fannie E. Jones; that said Margaret E. Peeler was on the sixth day of December, 1881, granted a divorce, from her husband by the circuit court of Alexander county, for his fault; that on the fifth day of February, 1882, she was married to Byron J. Atherton, by whom she had one child, a son, Homer Atherton, who was born on the second day of February, 1883; that said Byron J. Atherton died in the year 1884; that the said Margaret E. Atherton, on the third day of March, 1886, married James S. Roche, by whom she had three children,—Francis Roche, born in 1887, Leslie Roche, born in 1890, and Leon Roche, born in 1892; • that said Margaret E. Roche died on the 16th day of June, 1894.
It is averred in the bill that said Fannie E. Peeler (now Fannie E. Jones) was highly esteemed and regarded and greatly loved by her grandfather, the said Francis D. Atherton, and that it was his intention and purpose when he made said deed to make provision thereby for said Fannie E. and any other child or children his daughter, Margaret E., might have, either by said Byron J. or any other husband whom she might have, and that when he executed said deed he supposed that the words “and their bodily heirs,” as used in said deed, did or would in-*255elude the said Fannie E; and any other child or children whomsoever that might thereafter be born unto his said daughter, and that the consideration named in the deed was but nominal, and that the actual consideration wa's the desire of the said Francis D. Atherton to make provision for his daughter, said Margaret, and for her children, and that the word “their” in the phrase “their bodily heirs forever,” in the granting and habendum clauses of the deed, was employed with the understanding and intention on the part of said grantor in said deed that it meant and included all bodily heirs of his said daughter.
George W. Harrison, the justice of the peace before whom the deed in question was acknowledged, was called as a witness. He testified he was well acquainted with the grantor and with the grantees. He identified the original deed as the instrument which was acknowledged before him by said grantor. It was partly written and partly printed. The words “their bodily,” in each of the clauses of the deed, were in writing, the words “heirs forever” in print, and that he believed the written parts of the body of the deed were in the handwriting of Byron J. Atherton, one of the grantees. He further testified as follows:
Q. “Where did you take the acknowledgment?
A. “I took Francis D. Atherton’s acknowledgment in his store, about one hundred and fifty yards from his residence, and then I proceeded to the residence and took Mrs. Atherton’s acknowledgment.
Q. “How did you happen to be at the store on that occasion?
A. “I did my trading at the store, and was probably there for the purpose of trading at the store.
Q. “State whether or not you and Francis D. Atherton looked at or examined the deed, at his store, and had" any conversation about it.
A. “Yes, sir; we did.
*256Q. “State what he said to you about the deed, and give the conversation, or the substance thereof, as near as you can.
• A. “His eyes were not very good, and he asked me to read the deed over to him, and I did so. When I came to the words ‘and their bodily heirs,’ I asked him if he didn’t think that was wrong", and that it would cut Fannie Peeler, or any other children except Byron’s, out. He said, ‘No, it would not; I want all of Margaret’s children to share alike in the land.’ I asked him why he made the deed that way. He said, in reply, that he wanted Byron and Margaret to have a lifetime interest in the land, but so they could not sell it, and when they died he wanted her children to all share alike in the land.
Q. “When did that conversation take place—was it before or after you went to the house to take Mrs. Atherton’s acknowledgment?
A. “It was just before Francis D. Atherton signed the deed at the store and before I went to the residence to take Mrs. Atherton’s acknowledgment.
Q. “If in that conversation you made any suggestion to him about changing any word or words in the deed, please state what you said about the matter, and his reply.
A. “I suggested to him changing the word ‘their’ to ‘her’ in the expression ‘their bodily heirs, ’ and he said that would not make any difference,—that her children would all share alike anyhow.
Q. “Do you remember of any one being present at that conversation?
A. “Yes, Byron Atherton and Tom Smithey were there,- and all three of them argued against me about the effect of the word ‘their, ’ claiming that it would make no difference and that all of her children would share equally.”
The deed to Margaret E. and Byron J. Atherton, “to them and their bodily heirs forever,” conveyed what would have been at common law an estate tail special. *257(1 Coke on Litt. secs. 13-15, 283; 2 Preston on Estates, 413, 435-438; 2 Blackstone’s Com. 113, 114; 2 Bacon’s Abr.—1st Am. ed. 1811,—pp. 547, 548; Hopkins’ Hornbook on Law of Real Prop. pp. 43, 44; Lehndorf v. Cope, 122 Ill. 317.) Under the operation of section 6 of an act entitled “Conveyances,” (Hurd’s Stat. 1899, chap. 30, p. 401,) however, instead of an estate tail special a life estate was vested in Margaret E. and Byron J. Atherton, the remainder in fee going to their bodily heirs according to the course of the common law. (Frazer v. Peoria County, 74 Ill. 282; Lewis v. Pleasants, 143 id. 271; Dinwiddie v. Self, 145 id. 290; Kyner v. Boll, 182 id. 171.) The bodily heirs referred to are not Margaret’s bodily heirs nor Byron’s bodily heirs, but “their” bodily heirs,—that is, the bodily heirs of both Margaret and Byron,—which language excludes Fannie E. Jones and Francis D., Leslie and Leon Roche, and applies only to Homer Atherton, who is the only person who comes within the description of “their” bodily heir, —that is, the bodily heir of both of them. The remainder in fee was contingent, but vested in Homer Atherton upon his birth. (Dinwiddie v. Self, supra; Kellett v. Shepard, 139 Ill. 433.) The effect, therefore, of said deed was to vest in Margaret E. and Byron J. Atherton a life estate and the remainder in fee in Homer Atherton, as their only bodily heir, who is now the sole legal owner in fee of said lands.
The legal title to said land being in Homer Atherton, was the court below warranted, upon the case made, in reforming the deed, and, after such reformation, in decreeing four-fifths of said lands to be the property of the other children of Margaret E. Roche? We think not. The mistake insisted upon and sought to be corrected consists in the use of the word “their” instead of “her,” in the clause “to them and their bodily heirs forever,” found in said deed, and under which Homer Atherton takes title. There is no claim that said grantor, at the time he executed said deed, was not fully aware of its terms and *258language, or that he was in any way deceived, misled or otherwise imposed upon or subjected to any undue or improper influence. The evidence, on the other hand, clearly shows that the deed was read to him prior to the ex'ecution'thereof, and that he knew the word “their” was used and that the word “her" was not used in said clause; that he discussed the meaning of the terms employed at the time he signed and acknowledged the deed, and insisted he knew the legal effect thereof and that it expressed his meaning. It is therefore apparent that the mistake complained of is not a mistake as to what words were contained" in the deed, but simply as to the meaning and legal effect of the word “their” when used in the clause “to them and their bodily heirs forever.” This, manifestly, is not a mistake as to any fact. It is purely a mistake of law, and the rule in this State, subject to certain exceptions, among which this case does not fall, is firmly established that courts of equity will not lend their aid to relieve against mere mistakes of law.
In Fowler v. Black, 136 Ill. 363, where the mistake sought to be corrected consisted in the use of the word “heirs" instead of “children,” in a deed, Mr. Justice Bailey, speaking for the court, on page 378 says: “The general rule, subject, it is true, to certain exceptions, is, that courts of equity will not lend their aid to relieve against mere mistakes of law. Mr. Justice Story, in discussing the rule and its exceptions, after analyzing and reviewing at considerable length the leading decisions bearing upon the question, reaches the conclusion that the rule is relaxed in cases where there is a total ignorance of title founded in a mistake of a plain and settled principle of law, and in cases of imposition, misrepresentation, undue influence, misplaced confidence or surprise. ‘But,’ says the learned author, ‘it maybe safely affirmed, upon the highest authority, as an established doctrine, that a mere naked mistake of law, unattended by any such special circumstances as have been above suggested,*259will furnish no ground for the interposition of a court of equity.’ (1 Story’s Eq. Jur. secs. 137, 138.) The general rule above laid down has been frequently recognized and enforced by this court.”
In Sibert v. McAvoy, 15 Ill. 106, on page 109 the court say: “If he misconstrued the contract as written, that was a mistake of law and not of fact, and for such mistakes equity can grant no relief. It is where parties intended to insert words in a contract which were by accident omitted that equity can reform the contract by inserting them or by expunging words they did not intend to have inserted. If the words are written as the parties intended they should be written, or supposed they were written, when they signed the contract, no matter how much they may be mistaken as to the meaning of those words, no relief can be granted, either at law or in equity. The construction of words is a matter of law; the insertion of words is a matter of fact. It is for mistakes of fact, alone, that contracts may be reformed.”
In Gordere v. Downing, 18 Ill. 492, an agreement had been made for the sale of land. The parties went to a justice of the peace for the purpose of executing and acknowledging a deed. The grantor declined to make a deed containing covenants of warranty and directed the justice to prepare a quit-claim deed. The justice took a printed form for a deed of general warranty and filled it out by striking out the words “warrant and defend,” and leaving language in the deed preceding these words which amounted, in law, to a covenant of title in fee. He then informed the parties that the deed so altered was the same, in effect, as a quit-claim deed. The parties then read the deed over, expressed themselves satisfied with it, and it was executed and delivered. It is said: “There is no ground of fraud in the bill or proofs or of mistake of fact, but it plainly appears that the parties and the justice were mistaken in the legal effect of the deed. Each party, for himself, read the deed and is *260presumed to have known the language it contained; but the legal effect of that language is different from what they understood it to be or intended. They knew the facts, the parties to the deed, the consideration, the description of the land. They knew what words of covenant were stricken out of and what remained in the deed, but they were mistaken in the law,—in the legal consequence of retaining those words in the deed. This was a mistake of law in the legal effect of the language used and adopted by the parties, which, in the absence of fraxid, and where there is no mixture of oppression, confidence abused or surprise in matters of fact, equity will not relieve against. This rule is too well settled to admit of argument.”
In Goltra v. Sanasack, 53 Ill. 456, the complainants, who were children by a former marriage, filed a bill for the purpose of having a deed reformed, and it was alleged-that their father purchased the land and intended to have the same conveyed to his wife and his children, but contrary to his intention it was conveyed to his wife and her heirs, and not to her and all his children. In denying the relief prayed for it is said, on page 458: “The rule is inflexible that a mistake or misapprehension of the law is never relieved against or corrected. If a party designs to and performs an act under a mistaken view of the law affecting the transaction he is held to the obligation incurred. As a matter of necessity all persons are presumed to know and act in view of the law, and the maxim is, that ignorance of the law excuses no one.”
In Purvines v. Harrison, 151 Ill. 219, on page 223 the court say: ■ “To justify the reformation of a written instrument upon the ground of mistake, it is necessary, first, that the mistake should be one of fact and not of law; (Sibert v. McAvoy, 15 Ill. 106;) second, that the mistake should be proved by clear and convincing evidence; (2 Pomeroy’s Eq. Jur. sec. 862;) third, that the mistake should be mutual and common to both parties to. the in*261strument. (Sutherland v. Sutherland, 69 Ill. 481.) A mistake of law is an erroneous conclusion as to the legal effect of known facts. (Hurd v. Hall, 12 Wis. 113.) The construction of words is a matter of law. (Sibert v. Mc-Avoy, supra.) Where parties instructed an officer to prepare a quit-claim deed for their execution, but he drew a deed containing language which amounted, in law, to a covenant of title in fee, and they signed the deed knowing that such language was in it, they were held to have been mistaken in the law,—that is to say, in the legal effect of the language used and in the legal consequences of retaining such language in the deed.—Gordere v. Downing, 18 Ill. 492.”
In Seymour v. Bowles, 172 Ill. 521, on page 524 it is said: “The allegation in the bill that in drafting the deed the word ‘heirs’ was mistakenly used for ‘children’ presents no case for the correction of a mistake or reformation of the deed. The alleged mistake is one of law, and can not be corrected.”
In Butterfield v. Sawyer, 187 Ill. 598, on page 602 it is said: “In giving construction to deeds we are confined to the terms of the instrument itself, the object being to ascertain the intention of the grantor as expressed by the language used, and not the unexpressed purpose which may at the time have existed in his mind. Where there is no ambiguity in the terms used, or where the language used has a settled legal meaning, the instrument itself is the only criterion of the intention of the party.”
The,cases of Dinwiddie v. Self, supra, and Kyner v. Boll, supra, relied upon by appellees, can readily be distinguished from the case at bar. In the Dinwiddle case an unmarried woman purchased of the defendant a fee simple title to a 220-acre farm for $9000, that being the full value thereof. She entrusted her brother to close the purchase, and gave him instructions to have the lands conveyed to her absolutely in fee, as her sole and separate property. Without her knowledge or consent- he *262accepted a deed which conveyed the lands to the complainant and “her bodily heirs.” On a bill in chancery the court reformed said deed so as to convey to the. complainant a fee instead of a life estate in said farm, on the ground that the limitation to the “heirs of her body” was inserted in the deed wholly without her knowledge, authority or consent. In discussing the right of the complainant to such relief, the court, on page 304 of the opinion, say: “If * * * she had personally requested the insertion of this limitation or had accepted the deed with full knowledge of its terms she would have been bound by the instrument as executed, however much she may have been mistaken as to the legal effect of the language thus employed.” In the Kyner case the grantor in the deed sought to be reformed, so soon as he discovered that the same was made to the grantee and her “bodily heirs,” carried the same back to the justice of the peace who had prepared the same and before whom the same had been acknowledged, and requested that the word “bodily” be stricken out of the deed, and upon the justice declining to strike out such word the grantor immediately caused to be executed and delivered to the grantee another deed conveying to the said grantee the premises sought to be conveyed, in fee. In both of these cases words were inserted in the deeds sought to be reformed, without the procurement, knowledge or consent of the grantees, which limited the title to a life estate in the grantee when it was the intention of the grantor to convey the fee, and the court in each case, upon well recognized principles, properly expunged such words of limitation therefrom. In the case at bar the deed was written as the grantor intended it should be written. He knew its contents, but was mistaken as to the legal effect thereof. “It is where parties intended to insert words in a contract which were by accident omitted that equity can reform the contract by inserting them or by expunging words they did not intend to have inserted. If the *263words are written as the parties intended they should be written or "supposed they were written when they signed the contract, no matter how much they may be mistaken as to the meaning of those words, no relief can be granted, either at law or in equity.” Sibert v. McAvoy, supra.
It is clear from the foregoing authorities, and many more which might be cited, that this is not a case for equitable relief, and that the decree reforming said deed is erroneous. The decree will therefore be reversed and the cause remanded to the circuit court, with directions to that court to dismiss" the bill for want of equity.
Reversed and remanded.
