delivered the opinion of the court:
The decree of the court below was in favor of the present appellants, so far as it held the will of the testator to be valid, and against the appellees, who sought to set aside the will, as well as the codicil. The decree was adverse to the appellants in holding the codicil to be invalid, and setting it aside, but in that respect it was in favor of the appellees. The present appeal, prosecuted by the appellants, seeks to reverse the decree in so far as it holds the codicil to be invalid. The appellees assign no cross-errors in relation to that part of the de*191cree which sustains the will, and make no complaint of the same. The only question in the case, therefore, is, whether or not the codicil of the deceased testator, David Henline, was invalid and properly set aside.
The grounds, upon which it is sought to impeach the codicil, are lack of testamentary capacity and the exercise of undue influence. As is usual in cases of this character, there is great conflict in the testimony. The appellants here, proponents of the will below, examined twenty-six witnesses. The appellees here, complainants below, examined twenty-two witnesses. Of these forty-eight witnesses many give it as their opinion that the testator had such mental capacity as that he was able to transact ordinary business, while many of them are of the contrary opinion. In cases of this character the verdict of the jury is to have the same force and effect, as is given to a verdict in a case at law under a like state of facts; and when the verdict in such case is not manifestly against the weight of evidence, the court is bound by it in the same manner and to the same extent, as if it were a case at law. The jury had before them and saw the witnesses. The judge who tried the case was satisfied with the verdict and acted upon it. The evidence, particularly upon the question of mental capacity, is conflicting, but a careful consideration of it does not show, that the finding of the court below is clearly against its weight. Where the testimony is thus conflicting and is not clearly against the weight of the evidence, the finding of the jury must be regarded as conclusive. (Calvert v. Carpenter, 96 Ill. 63; Buchanan v. McLennan, 105 id. 56; Greene v. Greene, 145 id. 264).
There is another rule upon this subject well settled by the decisions of this court; and that rule is, that, where there is an irreconcilable conflict in the testimony touching the facts, upon which the validity of the will depends, the decree of the lower court will not be reversed, if the evidence of the successful party, when considered alone, *192is clearly sufficient to sustain the verdict. (Calvert v. Carpenter, supra; Moyer v. Swygart, 125 id. 262; Bevelot v. Lestrade, 153 id. 625; Harp v. Parr, 168 id. 459).
A reference, however, will be made to some of the facts, so far as it is necessary to understand the questions of law involved, and the objections made to the admission of evidence and to the instructions given upon the trial of the case in the court below.
The deceased, David Henline, was about seventy-three years of age when he died on May 4, 1895. He was a bachelor, never having been lawfully married. He had two brothers at the time of his decease, named William and John, and several nephews and nieces. He had been eng'aged in business with h is brother, William, many years, and was a partner with him in the ownership of a considerable quantity of land. In 1868, or 1869, the brothers met with reverses in business. David’s mind seemed to have been so seriously affected thereby, that he secluded himself in a • room in the second story of his house for about a year, and during that time declined to do any business. During the remainder of his life he permitted his brother, William, to manage their business, and relied mainly upon his judgment in matters relating" thereto. It is conceded by both parties, that the deceased, for many years prior to his death, perhaps as much as twenty-five years, sustained illicit relations with the appellant, Delilah Smith. Some time after this illicit relationship began, the said Delilah married a man by the name of Smith, with whom she went to Missouri and there lived for some months. During their stay there the appellant, Paulina Smith,- was born. Not long thereafter Delilah Smith and her husband returned to McLean county, where Smith died, and David Hen line and Delilah Smith and Paulina Smith, the latter being called in this record Susie Smith, lived together as one family until the death of David Henline. It is claimed by counsel for the appellants, that Paulina Smith was the daughter of David *193Henline; but she was born in lawful wedlock, while Delilah Smith and her husband were living together, and the presumption of law is, that she was their child. In 1890 the deceased, David Henline, while living with Delilah Smith and while sick in bed, was induced to buy a hotel in the town of Lexington for the sum of §4000.00. He moved into the hotel with Delilah Smith, who took charge thereof, and he lived there with her and her daughter until his death. While he was sick in the hotel in 1890, he made his will, dated December 24, 1890. In the summer of 1894 the deceased complained of a numb feeling in his right foot, leg and hand, and said that “it divided him up the back of his right side, and, when it got- to his head, he did not know anything, and he felt as if he was cut in two.”
About April 15, 1895, while visiting with one of his brothers, the deceased, David Henline, was taken sick and complained of the numbness in question, and said of it: “When it gets into my head I don’t know anything.” One of his brothers took him to the hotel at Lexington on Monday, April 15,1895. On the afternoon of Tuesday, April 16, 1895, he was obliged to go to bed, and remained there until he died. He was paralyzed. The right side of him and his right hand were numb and dead. He was unable to sit up in bed, and had to be propped up. He lost his power of articulation, and was unable to talk, or to write. He did not recognize bis friends, and, when spoken to, could only answer a part of the time “yes” or “no,” and a part of the time he would mumble out, in reply to questions, some such expressions as “um,” and “ah.” Those waiting upon him were obliged to rub his hands and body in order to promote circulation of the blood. The disease, of which he died, was softening of the brain. This disease progressed and more and more affected his brain from' the time he went to bed, on Tuesday, April 16, up to the day he made his mark to the codicil, which was Monday, April 22. During the week *194before the codicil was signed, Delilah Smith and her daughter, Paulina Smith, were living in the hotel where the deceased was lying sick, and most of the time were in the same or an adjoining room. The testimony shows, that, at this time and for some time before, the appellant, Paulina Smith, was living at the hotel in a state of adultery with a man named Al. Smith, the son of Shelton Smith, the executor named in the will. Al. Smith lived at the hotel, or was there most of the time, and was the father of an illegitimate child by said Paulina. A man, named William Costello, lived and boarded at the hotel. One of the witnesses says, that one evening, during the sickness of the testator, Delilah Smith and Costello were in the cellar drinking beer; they had a keg of beer there and made such a noise as to seriously disturb deceased.
On the evening of Wednesday, April 17, one Buel Stevens, a livery-stable keeper in Lexington, was sent for by Delilah Smith, and had a talk with her and her daughter at the hotel. She requested Stevens to go into the room where the deceased was sick, and ask him to make a will, giving a certain 160 acres of land to her and her daughter, Susie or Paulina. Stevens went into the room in pursuance of this request, and asked the deceased if he would make such a will. He refused to do anything of the kind. Again, on Sunday morning, April 21, Delilah Smith went to the stable after Stevens, but failed to find him in his stable. Later in the day she sent a messenger for him, but still failed to find him. On Sunday evening, April 21, Joseph Humphreys was present in the room where Al. Smith and Mrs. Smith and Susie were. He came to inquire how David Henline was, and was requested by Delilah Smith to go in and talk to the testator upon the subject of making a will, but Humphreys declined to do so, and told them to send for Stevens. He says, however, that he went into the room where the dedeased was, and the latter was lying with his eyes and mouth half open, and seemed to be half asleep. Al. Smith *195then went for Stevens, and Stevens came over. Stevens says, that Mrs. Smith had sent over and requested him to come immediately; that he found Mrs. Smith and her daughter and Humphreys; that Mrs. Smith told him she wanted him to talk with David; that she said she thought David was crazy; that she wanted him to tell David that she had sent for his brothers, William and Jack, and his nephew, John, and that they would not come to see him, and were only waiting for him to die to get what property he had. She had not sent for his brothers and nephew as she thus stated. She also told Stevens to tell him, that, if he would make a will and give her and Susie the 160 acres, “she would fire Costello, and Susie would fire Smith.” Stevens says that he told her it would do no good, as he had tried the same thing on the Wednesday previous without success, but that he went in to see the deceased at her request and spoke to him; he was lying on his left side; he paid no attention; Stevens sat down by his side and took hold of his hand; it was cold; he asked him how he was feeling; he made a mumbling noise, and said: “Ah, ah, ah.” Stevens further says, that he told the deceased that he had been talking to Delilah and Susie, and they said they had sent for his brothers and nephew, and they refused to come and see him; that Delilah and Susie had promised, that, if he would make a will and give them 160 acres of land, Susie would “fire” Al. Smith, and she would “fire” Costello. All Stevens could get out of him was the mumbling noise heretofore referred to. At times he seemed to know what Stevens was talking about, and again he seemed either not to know, or paid no attention. He would turn his head away. Stevens returned to the room where Mrs. Smith and Paulina and Humphreys were, and told them that he had stated to the deceased all that he had been requested to state. A day or two before this, Shelton Smith, the father of Al. Smith, had gone to a justice of the peace to get a description of the land owned by the deceased. *196This was done at the request of Delilah Smith. On Monday morning, April 22, a justice of the peace, named Davidson, was seen by Stevens or Smith, and requested to come to the hotel to make the codicil.
When the codicil was made, Delilah Smith and Shelton Smith were in the room. A doctor named Hill, and the justice, Davidson, were also there. It appears from the testimony of these witnesses, that the deceased was unable to write; that a slate and pencil were brought in and handed to him, but he shook his head, not being able to use them; that he could not tell what he wanted, except as questions were asked; that a map was used and pointed to to indicate the location of his lands; but to all that was said and done he merely nodded his head, aud said nothing; when the mark was made, Davidson held the pen and the deceased took hold of the top of it, and Davidson wrote his name. Doctor Hill says, that he had the disease of the brain which causes aphasia, an impairment of the mind; that the cause of his death was the spreading of the disease over his brain; that his mind was impaired so far that he could not use language, and could not write, and all he could do was to nod and shake his head; that his cerebrum was probably inflamed at that time. None of his relatives were present when the codicil was made, and none of them were informed of the making of it, until after his death. Mrs. Edwards, an old lady, and the mother of the appellant, Delilah Smith, saj^s that her daughter refused to send for the deceased’s brother, William; that she, Mrs. Edwards, nursed the deceased during his sickness; that they could not understand what the deceased said or wanted; that she tried to make him understand, but he could not say a word that any one could comprehend.
In view of such testimony as has been above referred to, we are unable to say that the jury were not justified in returning the verdict which they rendered. The existence of an illicit relation between a deceased testator *197and his mistress will not give rise to a presumption of undue influence as a matter of law, but undue influence is more readily inferred in case of a will made in favor of a mistress than in the case of a will in favor of a wife. The existence of the relation is a circumstance to be considered by the jury, along with other facts in the case. “The influence of a lawful relation may result in testamentary dispositions which ought not to be set aside, when, if they resulted from the influence of an unlawful and immoral relation, they would produce deep suspicion,” the question to be determined being whether the influence exerted was undue or not. The jury have a right to consider the fact of the unlawful relationship where there is proof, as there is in the case at bar, tending to show constraint and interference, impaired mental capacity, loss of will power, and sickness or disease at the time of the making- of the will. (McClure v. McClure, 86 Tenn. 174; Johnson's Estate, 159 Pa. St. 630; Monroe v. Barclay, 17 Ohio St. 302; 27 Am. & Eng. Ency. of Law, p. 514).
This codicil was drawn in the absence of the near relatives of the deceased, at the instance and dictation of the beneficiaries in the will, and after false statements made by them as to the conduct and feelings of the absent relatives; and its terms are hostile and opposed to the terms of the will of December 20, 1890, executed in favor of such beneficiaries. These beneficiaries, moreover, lived with the testator, who was old and feeble. His mind was evidently so impaired, that he was more or less under the domination of Delilah Smith and her daughter. The will previously executed had given appellants 40 acres of land and a hotel building, and had given the remainder of his property to his legal heirs or representatives. The codicil, signed by the testator under the circumstances already detailed, went further, and gave them 800 acres of land, in addition to what had been devised by the terms of the will. There is nothing in the testimony of the witnesses to show, that the previous *198will was present or called to the attention of the testator when he signed the codicil, although the codicil upon its face refers to the will. The proof also shows, that the quantity of land mentioned by Mrs. Smith in her instructions to Stevens, as being desired by her through the will of the deceased, was 160 acres. Humphreys also testifies to 160 acres of land as being the amount mentioned in the conversation. But when the codicil was drawn, the quantity of land given thereby was 800 acres, .instead of 160 acres. It appears, that a map was used for the purpose of calling the attention of the testator to the location of the lands, but whether he in any way pointed to or designated the particular sections referred to in the codicil does not clearly appear. Many authorities mention, as features unfavorable to the validity of a will, and as indicating the probable exercise of undue influence, such concurring circumstances as the following: the departure from the terms of a previous testamentary disposition; the false impressions under which the instrument is made; the active agency of the beneficiary in procuring it to be drawn; the absence of those who had at least equal claims upon the justice of the testator; old age accompanied by feebleness and disease. (Tyler v. Gardiner, 35 N. Y. 559; Delafield v. Parish, 25 id. 35; Blewitt v. Blewitt, 4 Hagg. 463; Greenwood v. Cline, 7 Ore. 17; In re Hess’ will, 48 Minn. 504, and note to same in 31 Am. St. Rep. 685; 2 Lead. Cas. in Eq. p. 2, par. 1285). Where a will is procured to be written by persons largely benefited by it, it is a circumstance to excite a stricter scrutiny and requires stricter proof of volition and capacity. (McCommon v. McCommon, 151 Ill. 428; Purdy v. Hall, 134 id. 298; Byard v. Conover, 39 N. J. Eq. 244). The latter case of Byard v. Conover is somewhat similar in its facts to the case at bar. There, a bachelor, seventy-two years old, while in a moribund condition, signed a paper purporting to be a will, giving all his property to his housekeeper, who had lived with him for many years, *199and who had previously prepared the paper which was signed; none of the testator’s brothers and sisters were present, or informed of the making of the will; and it was held, that the paper should be refused probate on the ground of want of capacity and undue influence.
It is only necessary to notice certain objections urged upon our attention by counsel for appellants. It is said, that the allegations of the bill are not sufficiently specific in relation to the charges of fraud. This specific objection was not made in the court below, either by demurrer to the bill, or in opposition to the introduction of testimony, and, consequently, cannot be made here for the first time. If the allegations were not sufficiently specific in this regard, and attention had been called to them in the court below, the complainants there might have been permitted to amend their bill. (American Bible Society v. Price, 115 Ill. 623).
It is said, that the court below improperly admitted the conversation had between Mrs. Smith and Stevens in regard to what the latter was to say to the deceased upon the subject of making his will. Stevens must be regarded as the agent of Mrs. Smith and her daughter to communicate their wishes to the deceased in regard to the will. What she told Stevens to say to the deceased was so told on the evening before the codicil was executed, while she and her daughter were in a room adjoining that in which the deceased lay, and was for the purpose of influencing the deceased’s mind to make his will or codicil in a certain way. The main objection made to this testimony is, that Mrs. Smith and her daughter were both legatees under the will, and that admissions and statements of one legatee, prejudicial to the will, cannot be admitted where there are other legatees. As we read the testimony, both of the legatees, to-wit, Mrs. Smith and Paulina Smith, her daughter, were present when the conversations were had with Stevens and Humphreys in reference to the communications to *200be made to the deceased. By the terms of the will and codicil Mrs. Smith and her daughter were joint devisees. The property was devised to them.jointly Where the interest of the devisees is joint, the evidence may be admitted against all of them, and where the parties have a joint interest in the matter in suit, an admission made by one is, in general, competent evidence against all. (McMillan v. McDill, 110 Ill. 47; Southern Life Ins. Co. v. Wilkinson, 53 Ga. 535). Under our statute, parties are permitted to create the common law estate of joint tenancy, with its common law incidents, by expressly declaring in the instrument executed, that the estate conveyed shall pass in joint tenancy. (Mette v. Feltgen, 148 Ill. 357).
The first instruction given for the appellees is criticised, because it uses the expressions “alleged execution of the codicil” and “supposed codicil.” It is said, that the use of the words “alleged” and “supposed” was equivalent to telling the jury, that the codicil was not the real codicil of the testator. We do not think so. The proponents of the will allege that the codicil was valid. The appellees deny that it was valid. To speak of it as an “alleged” codicil was no more casting discredit upon its validity, than to speak of it as the “codicil” without the use of the word “alleged” would have been to make an announcement in favor of its validity. The question, submitted to the jury in this case, was, whether “the writing read in evidence, purporting to be the codicil of the will of David Henline, deceased,” was rea-lly his codicil. This is the form of expression used in all cases of contested wills where the question whether the paper is a will or not is to be submitted for their determination to the jury. It cannot be said that, because the instrument is spoken of as one “purporting” to be a codicil, the jury are thereby instructed that it is not a codicil. An instruction, making use of the word “alleged” in the same way in which it is here used, • was given in Campbell v. Campbell, 138 Ill. 612, and was approved by this court.
*201The first instruction given for the appellees is also criticised because of the following language: “The court instructs you, that if you believe from the evidence, that fraud was practiced on David Henline, deceased, in procuring the alleged execution,” etc. It is said, that the instruction is defective in not indicating the nature or character of the fraud, or the persons by whom it was exercised. Undue influence to avoid a will must be such as to overcome the free agency of the testator at the time the instrument is made, so as to substitute the will of the beneficiary, or some other person, for his will. What constitutes such undue influence will depend upon the circumstances of each case. But undue influence is a species of constructive fraud which the court will not undertake to define by any fixed words. Its exercise may be inferred in all cases where the power of the person, receiving a devise or other like benefit, has been so exercised upon the mind of the donor, as, by improper arts or circumvention, to have induced him to make the devise, or confer the benefit, contrary to his deliberate judgment and reason. (Shipman v. Furniss, 69 Ala. 555). It is immaterial by whom the undue influence is exercised, whether by a beneficiary or an outsider. (27 Am. & Eng. Ency. of Law, pp. 500, 501). The instruction was not erroneous for the reasons stated.
The second instruction is objected to, because it tells the jury that the law in the first instance casts the burden of proving the will and codicil upon the proponents alleging its validity. Such is the rule which has been adopted by this court in a number of decisions. (Harp v. Parr, 168 Ill. 459). It is said, however, that, under this instruction, the jury could not know that, after the burden of proof was in the first instance put upon the proponents, it had shifted to the contestants. If this was a defect, it was cured by the first instruction given for the contestants. The latter instruction told the jury that, when the proponents had proven the due execution of *202the will and codicil in. question, and the capacity of the deceased to make the same, by the signing witnesses, a prima facie case was made out in favor of the validity of the will and codicil, and then the burden of proof was shifted to the complainants to prove, by a preponderance of the evidence, some one or more of the grounds alleged against the validity of the will and codicil.
Objection is also made to the fourth instruction given for the appellees. This instruction is unobjectionable as it merely told the jury, in substance, that the condition of the testator’s mind at the time of the execution of the will was the real subject of inquiry. Such is the law. The sixth instruction given for the appellants announced the same rule, namely, that the deceased must be competent to make a will at the time when he made the codicil in question. The real question is, whether the testator, at the time of making the instrument purporting to be his will, had such mind and memory as to enable him to understand the particular business in which he was engaged. (Craig v. Southard, 148 Ill. 37).
The objection to the fifth instruction, given for the appellees, is disposed of by what has already been said in regard to the first. The seventh instruction given for the appellees, which defines what constitutes testamentary capacity, or a sound and disposing mind, agrees with the views on this subject laid down by this court in Campbell v. Campbell, supra, and Nicewander v. Nicewander, 151 Ill. 156.
It is said, that the eleventh instruction assumes that the testator was subjected to “repeated urgings,” and for this reason is defective. The instruction used the following' language: “If you further believe from the evidence that he was too weak to resist repeated urging, and that undue influence was brought to bear upon him,” etc. The instruction does not make the assumption charged against it, but leaves it to the jury to find, whether, as a fact, there was repeated urging. There was evidence in the record, tending to show that the *203testator was at least twice urged to make a will in behalf of the defendants. Counsel say that repeated urging does not constitute undue influence. Whether it does or not will depend upon circumstances; and, certainly, repeated urging in connection with other facts may be considered by the jury in determining whether undue influence was exercised. The instruction does not state that repeated urging is undue influence. Undue influence, however, has been defined to be “any improper or wrongful constraint, machination, or urgency of persuasion, whereby the will of a person is overpowered, and he is induced to do or forbear an act which he would not do, or would do if left to act freely.” (27 Am. & Eng. Ency. of Law, p. 453).
Some other objections are made to the instructions, ^but we do not deem it necessary to discuss them. Upon a careful review of the whole record, we are of the opinion that the decree of the court below was right.
Accordingly, the decree of the circuit court is affirmed.
Decree affirmed.
