Is it permissible for me to witness

Q 1: Is a marriage contract, witnessed by two witnesses who are relatives of the bride, the groom or the Waliy, such as a brother, son or grandfather, valid? Actually, some people claim that the contract as such is invalid, while others deem it to be valid. Please, tell us about the right position.

A: The marriage contract is valid if witnessed by relatives of the two spouses - except ascendants and descendants of the one marrying, i.e. father and grandfathers or sons and sons' sons - as they are not accusable.
