i AND MY WIFE WANT TO MAKE A WILL IN FAVOR OF SON HOW CAN IT BE MADE IRREVOCABLE.
will is never irrevocable. it becomes irrevocable if one does not revoke or change it before death.
contact a advocate to make a correct irrevocable will
in every will, it may be mentioned that the will is irrevocable and final but the same can be annulled by executing another will at a later stage.
