An 84 year old lady is about to sign a Sale Deed for a property. In order to ascertain that she is of sound mind, a doctor's certificate was insisted upon. The Doctor's Certificate states
"I have examined Mrs. xyz on dt. / time and she is physically fit for her age as on this day and time. She is normal."
Is this sufficient to conclude that she is of sound mind and capable of entering into a contract ?
An early response will be appreciated.
