“Registration of a will refers to the process where the will is registered by the testator at the office of the sub registrar. While registering the will, the testator must submit his identity proof, address proof and photograph and those of his witnesses, who accompany the testator to the sub registrar’s office. The advantage of registering is that the will is kept in the safe custody of the registrar and hence, cannot be tampered with. A registered will can also be withdrawn or overridden by a newer one.”
