kukosekana kwa uwezo wa mwili sio bar / kikwazo kwa kihalali mkataba. uwezo wa akili ni kikwazo kwa kihalali kuingia katika mkataba kwa sababu utawala ni kwamba unaweza kusimamia mambo yako kama wewe ni kiakili uwezo wa kuelewa kwa nini kufanya. kuharibika kimwili kama unaathiri uwezo wa akili bila shaka haina kuathiri uwezo wa mkataba.
