when she surrendered the bank book, and opened a new account, designating a new beneficiary. But Mrs. Krauth in this instance did more than change the beneficiary. She delivered the bank ■ book containing the new account to Mr. Jennings as the person entitled to the fund. These acts constituted a valid trust in favor of Jennings, and, unexplained, operated to transfer to him the beneficial interest in the money deposited. Bishop v. Bank,
33 App. Div. 181 , 53 N. Y. Supp. 488 ; Devlin v. Hinman, 34 App. Div. 107 , 54 N. Y. Supp. 496 ;
Willis v. Smyth, 91 N. Y. 297 ; Boone v. Bank,
84 N. Y. 83 ;
Mabie v. Bailey, 95 N. Y. 206 ; Cunningham v. Davenport, supra. Mrs. Krauth boarded with the Jennings family at the time, and there were reasons for making this provision in their favor, particularly as she had deposited a like sum in the New York Savings Bank in trust for Hennessy, who subsequently received the money. The court should not disturb the disposition made by Mrs. Krauth of her own money, except for some substantial reason. At the time of the transfer to Jennings, Mrs. Krauth was about 82 years of age, and the defendant claims that she was then of unsound mind, and incapable of legally making a change of beneficiaries. “Mere mental weakness, or inferiority of intellect, will not incapacitate a person from making a valid contract; nor is it easy to define the state of mind which will have this effect.” 1 Pars. Cont. (6th Ed.) 383. And it is elementary that any person may create a trust who is capable of making a valid disposition of property of any description. A trust once created can be attacked only by a preponderance of evidence proving facts rendering it invalid in law, the burden being on the assailant.
Jones v. Jones, 137 N. Y. 610 , 33 N. E. 479 . Mrs. Krauth’s mind was not so weak in 1890 as to disable her from business, or prevent her from acting with apparent intelligence, particularly in money matters. The bank officials intelligently understood her, and there seems to be no legal reason why the intention she deliberately expressed to them should be defeated by awarding the fund contrary to her will. On November 10, 1894, Mrs. Krauth was judicially declared to be an incompetent person, and the finding declares that such incompetency dated back to 1892,—about two years subsequent to the change of beneficiaries. She died September 11, 1897, and Hennessy thereafter qualified as her executor. The evidence offered, by which it was attempted to show the incompetency of Mrs. Krauth in 1890, is simply matter of opinion, founded on an examination made four years afterwards by Dr. Fitch, supplemented by what others had said as to her memory for some years preceding. It proves no condition uncommon to persons of her age, and fails to satisfy the judicial mind that reason had been dethroned prior to 1894. The legal presumption is that Mrs. Krauth was capable of doing what she did, and did precisely what she intended to-do. Jones v. Jones, supra. Her age did not disqualify her. The law does not look to age, nor to debility of body, if sufficient intelligence remains. Failure to remember names or incidental and unimportant events may, perhaps, indicate decay of memory; but this failure may exist to a very great degree, and yet the “solid power of understanding” remain.
