The heirs of Mary S. Pond, deceased, seek in this proceeding to set aside her will on the ground that she was mentally incompetent to make the same. The petition was contested by appellant, Katherine Faust, who was made both executrix and a beneficiary under the will.
The only issue raised by this appeal is whether deceased was competent to make a will. The evidence on this question was in direct conflict, and while we realize that the right to dispose of property by will is a valuable property right, of which we are loath to deprive a person except on clear and convincing evidence of incompetency to make the same, yet in this case the advantage of the trial court in *347hearing the witnesses and noticing their demeanor and candor, sympathy or bias, while testifying is of more importance than usual, for the case practically hinges on the credibility and capacity of witnesses. Courts will presume sanity until that presumption is overthrown by competent and reliable evidence to the contrary. From a careful examination of the evidence, which we will briefly discuss later, we are not prepared to hold that the evidence preponderates against the findings of the lower court.
We do not think a detailed discussion of the evidence necessary; but it is shown without much doubt that deceased was an aged, unmarried woman, living, at the time of her death, in Seattle; that she had frequent hallucinations .in which she imagined that she had painted pictures and written books, and that her deceased brother was sitting at the table with her; that she was at times flighty and could not carry on a coherent conversation. Some two years prior to January, 1914, the date the will was executed, deceased made a trip to New Jersey, and the testimony of one of her cousins, who was a physician and saw her on this trip, was to the effect that she was at that time suffering with a form of insanity known as incipient senile dementia. But the most conclusive evidence is the fact that, during her lifetime and three or four months after the execution of the will, a hearing was had and a guardian appointed for her because she was incapable of handling her own affairs and was of unsound mind. Both the physicians who examined her at this hearing stated that her mind was gone and that she was in an advanced stage of senile dementia; that such a condition does not result in a very short time, and that, in their opinion, judging from her condition at the time of their examination of her, she was not competent to make a will in the January preceding. While there is some evidence to the effect that deceased was competent at the time of making the purported will, to -devise her property, we think the preponderance *348thereof is with the court’s findings that she was incompetent, and therefore they should not be disturbed.
Judgment affirmed.
