Wills which are handwritten by the testator himself are known as Holographic Wills. These kinds of will have their own merit. Due to the fact that they are completely handwritten by the testator himself, raises a strong presumption[1] pertaining to their regularity and execution. It is held in various judicial pronouncements that “If there is hardly any suspicious circumstances attached to the will, it will require “very little” evidence to prove due execution and attestation of such a will”[2].
