One James Golder died in this state on August 23, 1914, leaving property and a will purporting to dispose thereof. He was 59 years- old at the time of his -death, and he left surviving him four children: Jean Shaver, aged 25 years; Ellen Johnson, aged 23 years; Theodora Golder, aged 21 years; and -Marguerite Golder, aged 19 years. By the terms of said will Ellen and Marguerite received $5 each, Theodora $4,000 and Jean the residue of all property, real and personal which probably amounted in value to some $20,000. Jean was appointed' executrix. When Jean proposed this will for probate, Ellen and Marguerite contested same, alleging testamentary incapacity and undue influence. The county court admitted the will to probate. Upon appeal and trial de novo, the circuit court admitted such will to probate. Upon appeal to this court we reversed the circuit court on questions of practice. In re Golder’s Estate, 37 S. D. 397, 158 N. W. 734. Upon second trial in circuit court such court made findings that said James Golder was, at the time of the execution of such will, of sound and disposing mind, and not acting under undue influence.
■From the judgment entered upon such findings and from an order denying a new trial, this appeal -was taken. The sole question for our consideration is whether or not the trial court erred in the above findings.
*593There are certain propositions that are so well established as to need no citation of supporting authorities; others that have been settled in this jurisdiction by the decisions of this court; and others concerning which the courts are in dispute, but which we deem supported both by reason and the so-called, “weight of authority.”
[1-3] Every person competent to contract has a right, given by statute, to dispose of property by will subject only to such limitations as a sound public policy may dictate. In the exercise of such right he may obey the dictates of his own will and feelings whether they are such as others would commend or ■ condemn. But while the foregoing is the unquestioned rule of law,, and while seemingly unjust and unnatural bequests or devises are not alone sufficient evidence of mental incapacity or undue influence, they are circumstances entitled to consideration and weight on both issues, and they may be sufficient to impose on the proponent “the necessity of giving- some reasonable explanation of the unnatural character of the will, or, at least, of' showing that its character is not the offspring of mental defect, obliquity or perversion.” Redfield on the Law of Wills, 515; Walls v. Walls (Ky.) 99 S. W. 969; Gay v. Gillilan, 92 Mo. 251, 5 S. W. 7, 1 Am. St. Rep. 712. “Although the testator has the abstract right of disposing of his estate by will as 'he may desire, yet a will which produces unnatural and unjust results demands close judicial scrutiny.” Alexander on Wills, 884. And “in order to sustain any unjust, unnatural, or absurd will * * * fair proof at least should be afforded that the testator was of sufficient capacity * * * to comprehend its import; and, furthermore,.the trier of the case should believe that neither essential mistake on his part nor the fraud nor undue influence of others about him produced so unhappy a disposition.” Schouler on Wills, etc., § 77.
[4, 5] The burden, under our statute, is upon the proponent of a will to establish the testamentary capacity of the testator. Section 998, Rev. Civ. Code, section 604, Rev. Code 1919; section 44, Rev. Prob. Code, section 3211, Rev. Code 1919; section 50, Rev. Prob. Code, section 3229, Rev. Code 1919. It was so held under similar statutes in Rayman’s Will, 42 N. W. 287, and in Seebrock v. Fedawa, 30 Neb. 424, 46 N. W. 650. This is the gen*594•erally recognized rule regardless of statutes. Alexander on 'Wills, •541, 547; 'Sehouler on Wills, § 225. In the light of section 50, ‘’Rev. Prob. Code, supra, which provides: '
“If the court be satisfied upon the proof taken that the will was' duly executed, and that the testator was, at the time of the execution thereof, of sound and disposing mind, and not acting ürider duress, menace, fraud or undue influence, a certificate of the pfoof and the facts so fouiid, signed by the judge and attested by 'the seal of the court, must be attached to the will”
' — the following from Alexander oh Wills, 543, is especially pertinent :
“The law requires that no will be admitted to probate except that of a testator of sound mind; and, unless the court is fully satisfied on this point, the instrument should be rejected.”
[6, 7] Where there is mental incapacity rendering one incompetent to make a will, there cannot be undue influence in a legal sense, as the existence of undue influence presupposes a will which, without such influence, would have been valid. Gwin v. Gwin, 5 Idaho, 271, 48 Pac. 295; Alexander on Wills, 880. One who is mentally incompetent to do a certain act cannot, as to such act, be the subject of coercion. But it is often- a close question whether the invalidity of a particular will should be placed upon mental incapacity or upon undue influence. _ Certain it is that while mere physical weakness is not necessarily evidence of undue influence (Hackett v. Hackett, 33 S. D. 208, 145 N. W. 437), evidence of physical and mental weakness is always material upon the question of undue influence (Ekern v. Erickson, 37 S. D. 300, 157 N. W. 1062; Schouler on Wills, § 226; 40 Cyc. 1146). As said in Alexander on Wills, 491:
“Undue influence is associated with testamentary capacity, since the amount of influence necessary to affect the testator varies according to the strength of his mind.”
[6] The burden is upon a contestant to establish undue influence. Ekern v. Erickson, supra. To sustain such burden, how- ' ever, it is only necessary that there be a preponderance of the ,, evidence showing undue influence. Schouler on Wills, § 242; Alexander on Wills, 9131. But, as above noted, where the will contains unjust or unnatural provisions, it demands close judicial *595scrutiny; the onus devolves upon the proponent to prove a reason^able explanation of the unnatural character of the ■ will; there, must be fair proof that the testator had'mental1 capacity to comprehend its import; and the court must, from all the evidence, be: led to believe that undue influence did not produce the unjust or unnatural disposition.
[9-12] Undue influence is not usually exerted'in the open, and it is therefore usually solely through inferences drawn from surrounding facts and circumstances that a court arrives at the conclusion that a will is the product of undue influence working on the mind of the testator. -Schouler on Wills, § 242; The relations of the parties, the conditions that surround them, the attitude that they occupy towards each other, the influences that control- their, actions (Gross v. Courtley, 161 Ky. 152, 170 S. W. 600), the-habits and inclinations of the testator, his purposes and wishes expressed at times and under conditions lending verity to his statements — all furnish guidance for the court. The keeping of the existence of a will secret from those who have an equal right to know of its existence is a badge of undue influence. Watkins v. Brant, 46 Wis. 425, 1 N. W. 82. Declaration of testator made previous to the execution of the will, and indicating a purpose inconsistent with the provisions thereof, “is competent and relevant, in connection with other evidence, as tending to show susceptibility to undue influence.” Ekern v. Erickson, supra; Schouler on Wills, § 242, p. 292. And it is also competent and relevant on the question of testamentary capacity. Alexander on Wills, 493, 494.; Redfield on Law of Wills, 537; Sheehan v. Kearney, 82 Miss. 688, 21 South. 41, 35 L. R. A. 102. In this latter case will be found a very exhaustive discussion and resume of the authorities upon the competency of such declaration as proof of undue influence. While mental delusions, which are not connected with or have no effect upon the testamentary act, are not sufficient to invalidate the will (Irwin v. Lattin, 29 S. D. 1, 135 N. W. 759, Ann. Cas. 1914C, 1044), yet evidence of such delusions are competent upon the question of general testamentary capacity.
[13, 14] Appellate courts should hesitate to reverse the decisions of trial .courts on questions of fact, and will do so only when it seems clear that its findings are contrary to the clear *596preponderance of the evidence, Hackett v. Hackett, supra. We agree with the court in Ott v. Boring, 139 Wis. 403, 121 N. W. 126, that in order that there ¡be a “clear” preponderance, “requires the preponderance to be so apparent as to manifestly outweigh any probable legitimate influence upon the triers [court] of those advantages for discovering the truth which the reviewing tribunal pannot have.” But the rule, requiring a clear preponderance of the evidence to sustain a reversal does not apply where it appears that the trial court applied wrong rules of law to the evidence. Kelley v. Crawford, 112 Wis. 368, 88 N. W. 296; In re Ball’s Estate, 153 Wis. 27, 141 N. W. 8.
[15, 16] In the light of the above, and keeping especially in mind the rule that the burden of establishing testamentary capacity rests upon the proponents of this will, and the further rule that, if the provisions of the will are apparently unjust or unnatural, it demands most close judicial scrutiny, and requires proponents to establish some reasonable explanation for such unjust or unnatural provisions — two rules which we feel certain the trial court did not fully recognize — we will review.some of the most salient facts disclosed by the evidence.
James Golder and his wife separated about the year 1906, and were divorced in 1910. They had five children; one son, who died prior to his father, and the girls hereinbefore mentioned. At the time of this separation the youngest girl was some ix 3>ears of age and the oldeát one 17. The three younger girls remained with 'their mother; the oldest girl and the boy were away at school, where they remained until old enough to go out for themselves. During vacations the oldest girl spent a part of her time with the mother, and the son was with her more, or less. There is no evidence but that the best of relations existed at all times between the children and their parents — there is not a word of evidence that any one of the children took sides as between the parents. 'The father never provided a home for any of the children, but some 4 years after the separation, and after the son and Jean had taken up claims, he "lived with one or the other until Jean mar-tied. There is ho evidence that he ever blamed or felt harsh to•ward any one of them for residing with the .mother, or that he ■ever had ahy trouble with any one of them, except when he was *597drunk. The evidence, other than that of respondents, shows that the relations ¡between Golder and the appellants were all that they should have been, and it clearly shows that he had an especially tender feeling toward the younger, whom he was wont to call his “baby.” Absolutely no just or natural reason appears why, in disposing of his property Golder should prefer Theodora over either appellant, even if it might be claimed that there was some evidence of a reason for preferring Jean over appellants. It does, however, appear that Jean used her influence in favor of Theodora. Jean lived at Winner. From about July i, 1914, and until his death, Golder, who for some time had been living at «Dallas (a town not far from Winner), lived with Jean. This was at the request of Jean. Theodora also lived with her. Ellen and Marguerite both lived at some distance from Winner, and their mother, a schoolteacher, made her home with Ellen during her vacations.
At the time this will was made, Jean owned 160 acres of land; her husband was in the mercantile business; they owned their home, and 'had one child; Theodora was unmarried, and undoubtedly without property; Ellen was married, had at least two children, lived in home owned by her husband and herself, which home was worth $2,500 and was mortgaged for $850; Marguerite was unmarried, a domestic, and undoubtedly without property. Golder owned 200 acres of land near Winner; held note of $11,000 secured by first mortgage on three quarters of land in Nebraska; had some $3,000 on deposit in a bank; and held some $5,000 of unsecured notes, $4,200 of which were executed by Jean’s husband.
Golder had for years been seriously addicted to the use of intoxicants, and, for several years prior to his death, he was afflicted with Bright’s disease. The evidence shows that Golder was approaching the last stages of this disease when he came to Winner. One doctor, who had made a special study of Bright’s disease, and who had treated Golder more or less for some time before Golder moved to Winner, was called to Winner to consult with the doctor then caring for Golder. This was on July 30th, either two or three days after the will was signed. This doctor testifies that Golder was in a condition of semicoma, in the very last stages of Bright’s disease; and the testimony of respondents themselves is that just before this — within a day or two at .most, and per*598haps the very day on which the will was executed — Golder had been much worse; had been unable to get out óf a chair for two days; was afflicted with a sort of coma. This doctor testified that Golder’s mentality on July 30th was dull on account of uremic poisoning; that he could not concentrate .his mind, and was not in full, possession of his ordinary intellect. He states that in case of a person in Golder’s condition. delusions and hallucinations might be apparent; and the undisputed evidence of disinterested witnesses shows that Golder did have delusions and hallucinations. He. pronounced him of unsound mind, and testified that such unsoundness of mind 'had extended back at least a month, and was of a. continuous nature. The doctor in whose continuous care he was from-as early as July 15 th testified to delusions which he had first noticed on July 15th, and also testified that from that time Golder rapidly grew worse until the time the other doctor was called in consultation. This doctor saw him every day but one from July 15th until he died, and he swears that during much of this time he was in a stupified condition.
A doctor who never saw Golder was called as a witness by respondents. This witness admitted that, where there is much uremia, it is bound to affect the mind of the sufferer; and he admitted that delusions might result from such poisoning. The two subscribing witnesses, neighbors of respondents and related by marriage to Jean, considered Golder of sound mind. One of them admits she knew Golder very slightly. A very close Dallas friend of Golder and his business confident, who came to Winner to see him the last of July, testified that there had been a„great change in his condition since'lie left Dallas; that his memory was gone. One S'joblin, who had'-'éx'cellent Opportunities to know whereof he testified, testified as to Golder having delusions, and that he considered -him of unsound mind. Other disinterested1 witnesses testified as to Golder’s physical and mental condition; that he was incoherent, his mind wandered, was not in full-possession - of his mental faculties; that he was “absolutely off.”- One witness, called by respondents, testified that Golder appeared to be of sound mind about the middle of July. Another says he was of sound mind, but there is no evidence that 'he saw him after May. Another, who lived part of the time at Jean’s home after Golder *599came there, thought him to 'he of sound mind. Appellants testified to Golder having delusions and to other facts evidencing mental and physical weakness; while respondents testified that they never knew of their father having delusions, and both testified to his mental soundness. The attorney who drew the will tes;tified to the conversation he had with Golder before the will was drawn, to how Golder related the family history in explanation of his reasons for disposing of his property as he did.
[15-17] In answer to hypothetical questions asked the several doctors, they answered, in-effect, that if, within several weeks before his death, Golder detailed all his property that he had and told about his past life and about his children, and stated what he wanted to do and the reasons he gave were true in fact, he was possessed of sufficient mentality to understand his property, and his relatives, those for whose being he was responsible. Without such answers to hypothetical questions, the proof of Golder’s mental incompetency was, to our minds, overwhelming. The only basis for such hypothetical questions is the conversation between Golder and the attorney, and there is no evidence that he ever mentioned to the attorney any of his property except the land, while there is evidence from other witnesses that Golder did not have a clear recollection of his property. The evidence of the attorney was objected to upon the ground that it was a communication of client to attorney and privileged. We are inclined to think the evidence properly received, but solely upon the ground that an attorney who drafts a will is presumed to impartially represent the estate and to be without bias. This presumption may hardly be justified in relation to an issue as to testamentary capacity, as any attorney would naturally 'hesitate to admit that he had drawn a will for a testator whom he considered to be without testamentary capacity. In this case we find this witness not remaining neutral, but appearing in court upon the trial as one of the attorneys for the proponents of the will. Knowing, as he must, that he would be called as a witness to testify to matters going to the merits of at least one issue raised by contestants, he should, in conformity with the nineteenth Canon of Ethics adopted by the Bar Association of this state and the American Bar Association, have refused to act as attorney for appellants. His evi*600dence is not entitled to that credence to which it would have 'been entitled if he had preserved that neutrality that a high sense of professional propriety would have demanded.
It appears beyond all question that Golder was naturally a hard-headed, obstinate person, one not easily influenced; and yet the almost undisputed evidence was to the effect that, after he came to Winner, he was easily influenced.
One old friend of 'Golder testified to Golder’s having, about the Holidays, 19 u, talked to him of all his girls, and pledged him to look after their interests; that he told Golder that, in his condition, he ought to make a will, and that Golder answered:
“Blame it, I don’t want to make a will, Uncle Tom. You know the laws of the state. I have no difference between these four girls. * * * The laws of the state are better than any will. Wiry should I make a will?”
Another old friend testified that Golder told him about dividing his property among his children, and indicated an especial interest in Marguerite. These last conversations were some years before Golder died, but, both of them clearly- show that Golder had, toward appellants, a fatherly feeling at a time when respondents contend Golder felt unkindly toward them- -because they lived with their mother. Another clearly disinterested witness testified that, shortly before the time Golder executed the will, he told him that he intended to give his property to all of his girls; and a witness, called by respondents, testified that on July 23d, probably the -day before the attorney received his instructions as to the will, Golder said he was going to give his property to Jean’s child. He told another witness, probably about May, 1914, that he was going to will his property to Jean, Theodora, and the child.
[18] .A close friend of Golder testified about Golder’s going to see one of Ellen’s- babies soon after it was born, and that Golder said he was going to give it $500. There is also evidence that he received letters from Ellen. And yet it is respondents', theory that Golder fairly hated his daughter. In fact Jean goes so far as to testify to her father’s gloating over the fact that he had his will fixed so that Ellen would not get any of his property. This daughter sought to testify that she had never had any trou*601ble with her father. This evidence was -wrongfully excluded on the ground that it related to transactions between this appellant and the testator.
It is undisputed that Jean talked with her father in relation to the disposition of his property, and was influential in getting him to give Theodora the $4,000. It is also undisputed that she opposed notifying appellants of the serious illness of their father, and that it was against Jean’s will and at Theodora’s demand that they were notified of his condition. She attempts to justify her acts on the ground that she was following her father’s desires. But it does not appear that any one else knew that such a desire existed, and surely her husband and Theodora would naturally have known of it if it had existed. Appellants were not notified of their father’s condition until one or two days after the will was executed. They came immediately, and were with him for nearly a -month, and until his death, and yet it is undisputed that Jean, while apparently treating them friendly, they staying at ’her home, did not advise them that their father had made a will. It is undisputed that as soon as the will was executed she went to get papers belonging to her father. It is also undisputed that she requested Ellen not to speak to her father of property matters. She testified that this was because her father complained that Ellen annoyed him by advising him- that he ought to get his property matters fixed up. Ellen denied that she talked to her father about such matters.
It appears from the clear preponderance of the evidence— being that of appellants and two disinterested witnesses as against the testimony of Theodora — that, when this will was first offered for probate, Theodora denounced the same as “crooked,” and laid the unjust and unnatural provisions thereof to the influence of’ Jean. There is evidence of a -disinterested witness that some settlement was made by Jean with Theodora. This probably explains why Theodora did not herself contest this will, as it is apparent she at first contemplated -doing.
[19] We are satisfied, beyond question, that the respondents willfully committed perjury when they testified that they never knew of their father’s delusions. The fact that they swore- falsely to this destroys the probative force of th-eir other testimony.
*602[20] It is respondents’ theory that Golder disposed of his property ass he did because he had divided his property with his wife when they were divorced; because 'Ellen and Marguerite remained with their mother and would probably receive what she had; because he did not feel kindly toward appellants, and especially toward Ellen; because he had lived with Jean considerably. The evidence shows that Theodora also remained with the mother until 1911, and there is absolutely no evidence that she-ever showed any greater interest in her father or his welfare than either Ellen or Marguerite. The overwhelming weight of the evidence shows that if Golder had any daughter whom -he looked upon with especial favor, it was his “baby,” Marguerite. The evidence does not reveal what property Golder had at the time of divorce, and, there is absolutely no evidence to show that, when Golder made the will, he believed, or had any reason to believe, that his former wife had any property. His “baby,” for whom he always appeared to have a very strong affection, appears to have no property or income other than that received for domestic service. Jean, least of any of the daughters, needed financial assistance. The only witness that gave any evidence that gave any support to the above theory, other than respondents themselves, was the attorney who drew the will, except a statement by Golder to one witness to the effect that he was going, to remember Jean in 'his will because she had been good to him, and a remark to the witness, to whom he said that he was going to give his property to Jean, Theodora, and the child. This witness testified that Golder said that the other two children would be taken care of by their mother. O'ne of these statements was about the date the will was made. The date of the other does not appear.
[21] We are therefore of the opinion that, while there might not ’be in the record before us sufficient from which to conclude that the will was the result of undue influence, provided such record showed -Golder to have been well and mentally normal at the time he executed this will, yet, in view of his enfeebled condition, both physical and mental, and the unjust and unnatural provisions of such will which the proponents have failed to reasonably explain, the clear preponderance of the evidence establishes that Golder, if not absolutely mentally incompetent to make a will, was *603so controlled in his act in making the will in question by the undue influence of his daughter Jean Shaver that the same was not his free act.
The judgment and order appealed from are therefore reversed.
