H. VENKATACHALA IYENGAR vs B. N. THIMMAJAMMA & OTHERS

The Supreme Court clarified that the mode of proving a will is governed by Section 63 of the Indian Succession Act, 1925, which mandates attestation. The court established that the onus is on the propounder to explain any suspicious circumstances surrounding the execution of the will. In this case, the appellant's significant involvement in the will's execution, which favored his sons, raised suspicion, leading the court to uphold the High Court's decision to set aside the trial court's finding of valid execution. The court emphasized that mere proof of signature does not suffice to presume the testator's knowledge of the will's contents.
