Eulalio Hernaez v. Rosendo Hernaez

Summary

This landmark 1903 Supreme Court case established key principles for will validity in the Philippines. Eulalio Hernaez challenged his deceased mother's will that favored his brother Rosendo, claiming mental incapacity and procedural defects. The Court upheld the will, establishing that mental capacity is presumed unless conclusively disproven, and that evidence of advanced age, illness, or receiving last rites alone cannot invalidate a will. The decision clarified that notaries may use interpreters when parties speak local dialects, witnesses need not have perfect Spanish proficiency, and special requirements for physicians and multiple interpreters apply only to specific circumstances (declared mental incapacity and foreign language wills respectively). The case reinforced the Civil Code's presumption of testamentary capacity and distinguished between various procedural requirements for different types of testamentary situations, providing important precedent for succession law in the Philippines.
