delivered the opinion of the court:
Adelbert C. Allen, by the name of D. C. Allen, filed a bill in the circuit court of Will county to contest the will of his father, Chester S. Allen, on the ground of mental incapacity. In accordance with the verdict of a jury a decree was rendered setting aside the will, and the defendants have appealed.
The assignments of error and the arguments' of counsel for the appellants question the sufficiency of the evidence to sustain the verdict, the exclusion of a witness offered by them and the giving and refusal of instructions.
Fourteen witnesses, including the attesting witnesses, testified on the trial to- the soundness of mind of the testator and eleven witnesses testified to his unsoundness of mind, all stating the facts which constituted the basis of their respective opinions. The evidence was such that a verdict in favor of the will could not have been set aside for want of evidence to support it, and if the verdict was in accordance with the preponderance of the evidence it cannot be said that the evidence was. of such a character that no' other verdict could reasonably have been found. The condition of the *192record is such that the verdict cannot be sustained if substantial error appeared on the trial. Such substantial error did occur in the rejection of the testimony of Etta P. Dille, who was offered as a witness by the proponents of the will. She was a daughter of Chester S. Allen and she and the complainant were his only heirs. Under the will all of the estate was devised, one-sixth to the complainant, one-sixth to Etta P. Dille and one-sixth to each of four Wesleyan Methodist bible schools situated in New York, South Carolina, Indiana and Kansas. Mrs. Dille was made a defendant to the bill and was offered as a witness by the defendants, but an objection to her competency on the ground that she was a party to the suit was sustained. The statute provides that no- party or persons directly interested in the event of a suit shall be allowed to testify therein of his own motion or in his own behalf where an adverse party sues or defends as the heir, legatee or devisee of any deceased person unless when called as a witness by such adverse party. The rule is, that it is the real interest that disqualifies a witness, and not the belief, understanding or feeling of the witness in regard to such interest. (Pyle v. Pyle, 158 Ill. 289; Campbell v. Campbell, 130 id. 466.) Under the will the witness was entitled to receive one-sixth of the residue of the estate. If the will were set aside she would receive one-half of the estate.. Her interest was identical with that of complainant. The statute is intended for the protection of a party suing or defending as an heir, legatee or devisee against the testimony of any person having an adverse interest. The only person entitled to object to the testimony is the adverse party suing or defending as heir, legatee or devisee. The parties to this suit, according to their legal, . actual interests, were the appellee and Mrs. Dille on the one side and the four bible schools on the other. The appellee could not object to Mrs. Dille’s competency, because he was not an adverse party. She was offered as a witness by the only parties who could have objected to her competency, *193and she should have been allowed to testify. Duffy v. Duffy, 243 Ill. 476; Enders v. Muno, 269 id. 422.
The appellee insists that the question, as to the competency of Mrs. Dille as a witness has been waived because not assigned as a ground for a new trial and not assigned as error. One of the points in appellants’ motion for a new trial and one of the assignments of error is that the court erred in excluding competent evidence offered on behalf of proponents. This raised the question of the competency of the witness.
The court refused the following instruction:
'“You are instructed that the owner of property, of lawful age, who has capacity to attend to his ordinary business, has the lawful right to dispose of it either by deed or by will, as he may choose, and it requires no greater mental capacity to malee a valid will than to make a valid deed. And if such an owner chooses to disinherit some of his heirs or leave his property to his other heirs or to strangers he has a legal right to do so, and such disposition of his property is valid, without regard to whether it is reasonable or unreasonable, just or unjust, and the reasonableness or justice or impropriety of the will are not questions for the jury to pass upon. If, therefore, you believe, from the evidence, that when Chester S. Allen executed the paper in evidence purporting to be his last will and testament he had mental capacity enough to know and understand the business in which he was then engaged, then the jury should find the paper in evidence to be the will of said Chester S. Allen.”
This was a proper instruction. (Schneider v. Manning, 121 Ill. 376; Taylor v. Pegram, 151 id. 106.) The appellee insists that it is covered by the following instruction which was given:
“You are instructed that the test of mental capacity of Chester S. Allen to make the will in question purporting to be his last will and testament is not whether he could trans*194act ordinary business, but the question is, did he have mental capacity sufficient to understand the business in which he was engaged at the time he made and executed said will; and if you believe, from the evidence, that Chester S. Allen had sufficient mental capacity to understand the business in which he was engaged at the time he made and executed said will, then it is your duty, under the law, to find said will to be the last will and testament of said Chester. S. Allen. And this would be true even though you may believe, from the evidence, that he was not capable of transacting ordinary business.”
This instruction did not tell the jury, as did the one which was refused, that it required no greater mental capacity to make a will than to malte a deed. There was evidence of the execution of deeds by the testator during the time in which his mental capacity was brought in question by the evidence, and the proponents had a right to have the jury told that it required no greater mental capacity to make a will than to malee a deed.' The instruction given did not cure the error in refusing the instruction asked.
Appellants insist that it was error to refuse the following instruction which they requested:
“You are instructed that a person may be so diseased, mentally, as not to be of sound mind and yet he might possess what the law terms a ‘disposing mind/ — that is, the mental capacity to know and understand the disposition he may wish to malee of his property and upon whom he will bestow his bounty. And in this case, if you believe, from the evidence, that Chester S. Allen, at the time he made the will in question, had a ‘disposing mind/ as above explained, then, in law, he had sufficient mental capacity to make a valid will.”
The instruction was properly refused. There is no distinction between a sound mind and a disposing mind.' A man having the capacity to malee a will is of sound and disposing mind, and the .meaning of that term and the ca*195pacity required to malee a will were amply explained to the jury in instructions which were given.
Two other instructions given for the appellee are also criticised, but we do -not regard them as subject to the objections made.
The decree of the circuit court will be reversed and the cause remanded.
Reversed and remanded.
