Signature or mark of the testator is necessary for unprivileged will. In certain cases, it may be signed by some other person in the presence of testator and under testator’s direction. However, it is always advisable to have will signed by the testator to avoid any future disputes. Every unprivileged will should be attested by atleast two witnesses, who have seen the testator or his agent signing the will. Each witness must sign the will in the presence of the testator. But it is not necessary that each witness should sign in the presence of other witness.
