In the Matter of the Testate Estate of Aida A. Bambao v. Cosme B. Sekito, Jr.

Summary

This case involves the probate of a will executed by Aida A. Bambao, a naturalized American citizen, in California. The Supreme Court reversed the lower courts' allowance of the will, holding that the proponent failed to prove California law governing the will's formalities, triggering the processual presumption requiring application of Philippine law. Under Philippine law, the will was fatally defective: it had only two witnesses instead of the required three, lacked acknowledgment before a notary public, witnesses did not sign every page, and the attestation clause was defective. The Court emphasized that substantial compliance cannot cure the mandatory requirement of notarial acknowledgment under Article 806 of the Civil Code. The case was remanded for compliance with Rules 132, Sections 24-25 regarding proof of foreign laws. The decision underscores the strict formality requirements for notarial wills and the necessity of proving foreign law when invoking its application in Philippine courts.
