One of my relative aged 90 years expired leaving a Will in favour of his widowed daughter-in-law assigning her the house owned by him. It was signed by two witnesses also, The property is in Chennai city. One of the witness now says she had signed as witness on the day the owner (the aged person who signed the Will) did sign & she signed later. If this point is brought by her or somebody, will there be any problem in implementing the Will to the daughter-in-law? Is it not a crime for the witness to sign though was not witness to the signature by the Executor?
