Linda A. Kucskar vs. Cosme B. Sekito, Jr.

The governing principle is that a foreign will seeking probate in the Philippines must comply with either the formalities of the testator’s domicile or Philippine law. Where the proponent fails to plead and prove the governing foreign law, Philippine law applies by processual presumption, and strict compliance with Articles 805 and 806 of the Civil Code becomes indispensable. Consequently, a will that is not acknowledged before a notary public and suffers from defective attestation cannot be validated under the rule of substantial compliance.

Aida A. Bambao, a naturalized American citizen residing in California, executed a Last Will and Testament on October 28, 1999, designating her cousin Cosme B. Sekito, Jr. as special independent executor for her Philippine assets. The instrument contained an attestation clause signed by two witnesses, omitted the total number of pages, lacked signatures on each page, and was never acknowledged before a notary public. Aida died in California on February 5, 2000. Her sister, Linda A. Kucskar, contested the probate, while the designated executor sought its allowance and appointment as special administrator.

• Aida A. Bambao executed a Last Will and Testament in Newport Beach, California, on October 28, 1999. The instrument nominated Cosme B. Sekito, Jr. as special independent executor for her Philippine assets and included an attestation clause signed by two witnesses. The will did not specify the total number of pages, lacked witness signatures on each page, and was never acknowledged before a notary public.
• Following Aida’s death in California on February 5, 2000, Cosme filed a petition for the allowance of the will and appointment as special administrator before the RTC of Pasig City. Linda A. Kucskar, Aida’s sister and a named heir, opposed the petition, alleging defects in the attestation clause and claiming she bore the expenses of Aida’s adopted minor child.
• The parties stipulated that the submitted copies of the will and a Revocable Living Trust were faithful reproductions of the originals. The RTC appointed Cosme as special administrator and granted the petition for allowance on August 4, 2011, finding conclusive proof of due execution.
• The CA affirmed the RTC’s ruling on August 31, 2017, invoking Article 809 of the Civil Code and the rule on substantial compliance to overlook the attestation defects. The CA held that sufficient compliance with statutory formalities warranted allowance.
• Linda filed a petition for review on certiorari, contending that the will failed to meet Philippine legal requirements and that the applicable California law was never alleged or proven.

• Petitioner maintained that the will should be disallowed because the proponent failed to allege and prove the foreign law governing its formalities. She argued that the instrument violated Philippine statutory requirements, specifically the absence of notarial acknowledgment, the use of only two witnesses instead of three, the failure of witnesses to sign each page, and the omission of the total page count in the attestation clause.

• Respondent contended that the will substantially complied with statutory formalities under Article 809 of the Civil Code, rendering minor defects in the attestation clause immaterial. He further argued that petitioner was estopped from contesting the allowance due to prior pleadings indicating no opposition to the will’s approval, and that the accompanying Revocable Living Trust corroborated the testator’s intent.

• Procedural Issues:
  • Whether the failure to plead and prove the governing foreign law warrants the application of Philippine law through processual presumption.
  • Whether the doctrine of estoppel bars the petitioner from contesting the probate of the will.
• Substantive Issues:
  • Whether the will’s failure to secure notarial acknowledgment, its deficiency in the number of attesting witnesses, and its defective attestation clause justify disallowance under Philippine law.

• Procedural: The Court held that foreign laws do not prove themselves and must be properly pleaded and proved as facts. Because the proponent failed to present authenticated copies of the pertinent California law, the doctrine of processual presumption applies, and Philippine law governs the probate. The Court further ruled that estoppel cannot bar a party from challenging a will’s formalities, as probate proceedings implicate public interest and require strict verification of execution circumstances.
• Substantive: The Court disallowed the will for failing to satisfy mandatory formalities under Articles 805 and 806 of the Civil Code. The instrument lacked the requisite three witnesses, omitted page signatures, and failed to state the page count in the attestation clause. Crucially, the total absence of notarial acknowledgment cannot be cured by the rule of substantial compliance, which only applies to imperfections discernible from the will itself. The Court emphasized that evidence aliunde, such as the Revocable Living Trust, cannot supply missing execution formalities.

• Processual Presumption — Courts presume that unproven foreign law is identical to domestic forum law. The Court applied this doctrine to subject the California-executed will to Philippine formalities after the proponent failed to present authenticated copies of the governing California statutes.
• Substantial Compliance in Attestation — Defects in the attestation clause may be disregarded if the will itself reveals compliance with statutory requirements. The Court clarified that this rule cannot cure the complete absence of mandatory elements, such as notarial acknowledgment or the explicit statement of page count in the attestation clause, which serve as essential safeguards against fraud.
• Non-Applicability of Estoppel in Probate Proceedings — Parties cannot be estopped from raising formal defects in a will due to prior conduct or pleadings. The Court applied this principle to hold that public interest mandates strict judicial scrutiny of testamentary execution, regardless of a party’s earlier acquiescence.

• "In international law, the party who wants to have a foreign law applied to a dispute or case has the burden of proving the foreign law. The foreign law is treated as a question of fact to be properly pleaded and proved as the judge or labor arbiter cannot take judicial notice of a foreign law." — The Court invoked this principle to establish the proponent’s failure to discharge the evidentiary burden, thereby triggering processual presumption.
• "The rule must be limited to disregarding those defects that can be supplied by an examination of the will itself... But the total number of pages, and whether all persons required to sign did so in the presence of each other must substantially appear in the attestation clause, being the only check against perjury in the probate proceedings." — The Court adopted this limitation to reject the appellate court’s expansive application of substantial compliance to the will’s defective attestation.
• "Estoppel is not applicable in probate proceedings because they involve public interest. Otherwise, the truth as to the circumstances surrounding the execution of a testament may not be ascertained which is inimical to public policy." — The Court applied this doctrine to invalidate the trial court’s reliance on petitioner’s prior pleadings to foreclose challenges to the will’s validity.
