Inadequacy of consideration may be found in connection with weakness of mind and the combination of facts may be such as to sustain a finding of undue influence,1 even though he is not absolutely lacking in capacity to make a contract. A conveyance by a woman of between sixty and seventy, in very poor health, of doubtful mental capacity, made a few weeks before her death, of property worth from six to eight thousand dollars, in consideration of a payment of two hundred and fifty dollars in cash, and an annuity of five hundred dollars for life, together with doctor's bills, was set aside.2 A release by one who was of inferior mentality, by which he accepted two hundred dollars for eighteen years' work, may be set aside, especially if the evidence shows that he did not understand that such payment was in full.3 A conveyance by an aged man of weak mind for the purpose of securing a loan will be held to be a mortgage.4 A conveyance of property worth one thousand dollars by a grantor who is mentally weak, in consideration of a payment of seventy-five dollars, will be set aside.5
