Is the grandmother's statement "they will believe her" considered an absolution of the debt, and should her words be taken into account while she is unconscious?

Such phrases as: "Do not speak of what you and your children possess," and "Who told you to transfer the money?" do not establish ownership, as they are said as a courtesy and do not explicitly indicate a waiver of money. As for her saying, "Donate it," she was at that time unconscious and not legally competent to act. Therefore, the heirs must be informed of her desire to donate the remaining money. If they agree, they may donate it on her behalf; if they refuse, the money reverts to the heirs and is divided as part of the inheritance.
