Santos vs. Republic
Case
G.R. No. 221277
Decision Date
Mar 18, 2021
Eduardo Santos sought to correct his birth certificate, changing his surname, nationality, filiation, and mother’s civil status. The Supreme Court dismissed his petition, ruling substantial changes require adversary proceedings and proper parties must be impleaded, but allowed refiling for surname change.

Case Summary (G.R. No. 221277)

Factual Background

Eduardo invoked Rule 108 on the theory that his COLB contained incorrect civil registry entries. He averred that, although his parents cohabited as common-law partners, his father allegedly had a subsisting marriage to a Chinese woman in China. Eduardo claimed that he was born out of a relationship not supported by a valid marriage between his parents. He maintained that he had always used his mother’s surname, “Santos,” in his dealings and transactions. Eduardo also alleged that he had elected Filipino citizenship in due time.

To support his petition, Eduardo presented evidence, including his Election of Philippine Citizenship and Oath of Allegiance, an affidavit of Juana Santos stating that Eduardo was illegitimate because she was not legally married to his Chinese father, documents evidencing that he exercised suffrage, his judicial affidavit, his COLB, and death certificates of Juana Santos and Cu Lay, the latter indicating that he was married to a person in China. Eduardo also offered documents intended to show his use of the surname “Santos.”

Proceedings in the Regional Trial Court

On February 22, 2013, the RTC granted Eduardo’s petition. The RTC ordered the Local Civil Registrar of Manila and the National Census and Statistics Office to effect corrections in the entry of Eduardo’s birth certificate: first, to change the surname to “Santos”; second, to correct filiation from “legitimate” to “illegitimate”; third, to correct nationality from “Chinese” to “Filipino”; and fourth, to change his mother’s civil status from “married” to “single.” The RTC directed issuance of the corrected certificate upon the decision’s finality and payment of the required legal fees, and required furnishing copies of the decision to the Local Civil Registrar of Manila, the Office of the Solicitor General, and the National Statistic Office.

The RTC found that Eduardo complied with the publication requirement under Section 4 of Rule 108. It also rejected the public prosecutor’s stance that Eduardo’s evidence was hearsay and self-serving, and that his remedy was misplaced in view of his alleged admission that he was Chinese by birth. The RTC concluded that Eduardo had sufficiently established his entitlement to the requested corrections.

Ruling of the Court of Appeals

The CA modified the RTC ruling. It partially reversed and set aside the RTC decision by declaring Eduardo a Filipino citizen, but refusing to alter the surname and filiation entries. Specifically, the CA directed that Eduardo’s surname should remain “Cu” and that he should remain a legitimate child of his father, Nga Cu Lay.

The CA agreed that Eduardo’s citizenship was Filipino, reasoning that the 1935 Constitution, effective at the time of Eduardo’s birth, recognizes as Filipino a child born of a Filipino mother who elects Philippine citizenship upon reaching the age of majority. However, on the issue of filiation, the CA held that Eduardo failed to overcome the legal presumption of legitimacy. The CA treated the COLB as a formidable evidence for legitimacy and invoked the concept that, after the lapse of periods specified in the Family Code (as stated in the CA’s discussion referring to Article 170 and, in proper cases, Article 171), the action to impugn legitimacy becomes legally infeasible, thereby fixing the status presumed by law and rendering it unassailable. The CA further stated that only the father, or in exceptional instances the father’s heirs, can contest legitimacy through the appropriate action brought under the Family Code framework.

The CA also scrutinized Juana’s affidavit and concluded that it did not adequately establish illegitimate filiation. It reasoned that a child born during a marriage is considered legitimate even if the mother had declared against its legitimacy or had been sentenced as an adulteress. The CA opined that giving full weight to Juana’s affidavit would improperly confer a right that, under the law, belongs exclusively to the husband and, in proper cases, his heirs.

Eduardo’s motion for partial reconsideration was denied by the CA on October 13, 2015 for lack of merit.

The Parties’ Contentions Before the Supreme Court

Before the Supreme Court, Eduardo insisted that the CA failed to accord proper evidentiary weight to Juana’s notarized affidavit. He argued that the affidavit should be admitted and credited, enjoying the presumption of regularity, and should be sufficient to establish his illegitimate status. He attached a purported Certificate of No Marriage (CENOMAR) from the NSO to show that Juana did not appear in the National Indices of Marriage.

On the surname issue, Eduardo maintained that he should be allowed to use his mother’s surname, citing his consistent use of “Santos” in dealings and transactions supported by documents presented. He also contended that the limitations in Article 170 of the Family Code restricting the action to impugn legitimacy to the husband or his heirs presuppose a valid marriage between the parents. Since, in his view, his parents were not legally married, he argued that the statutory restriction could not apply.

The OSG, in its Comment, opposed the petition. It argued that Juana’s affidavit could not establish pedigree or the relationship between Eduardo and his parents without testimony from another family member. It also asserted that, even if Eduardo could testify as to Juana’s affidavit, the Family Code bars Eduardo and Juana from questioning Eduardo’s legitimacy. Finally, it submitted that the CENOMAR could not be considered because it had not been presented and formally offered during trial.

Core Issue

The Supreme Court framed the principal issue as whether Eduardo could impugn his legitimate status and claim that he was a Filipino citizen through a petition for correction of entries in his COLB filed under Rule 108.

Legal Basis and Reasoning: Scope of Rule 108 and Jurisdictional Considerations

At the outset, the Court noted that neither party assailed the RTC’s authority to order corrections through a petition under Rule 108. Nonetheless, the Supreme Court treated as indispensable the propriety of the remedy Eduardo availed, because that determination would control whether the CA decision should be upheld.

The Court emphasized the principle that issues not raised in the assignment of errors are ordinarily not considered, citing Section 8, Rule 51 of the Rules of Court and related jurisprudential formulations on review of unassigned errors when essential and indispensable to a just resolution. Applying these principles, the Court held that it was empowered to consider errors affecting the validity of the proceedings and, where necessary for complete adjudication, could waive lack of proper assignment.

On the substantive procedural framework, the Court pointed to Section 2 of Rule 108, which enumerates the entries in the civil register subject to cancellation or correction. It then clarified, through Republic v. Valencia, that Rule 108 permits not only clerical corrections but also substantial changes. The Court further relied on the distinction reiterated in Republic v. Tipay: if the correction is clerical, the procedure is summary; if it affects civil status, citizenship, or nationality, it is substantial and must proceed adversarial.

The Court found that Eduardo’s requested corrections were not mere clerical errors. He sought substantial changes affecting, among others, filiation, nationality, and the civil status of his mother, as well as a change in surname from “Cu” to “Santos.” The Court reasoned that such changes were grave and would affect not only identity but also consequential rights, including successional rights. Accordingly, the proceeding had to conform to the requirements for substantial corrections under Rule 108.

The Court then applied the procedural safeguards in Sections 3 to 5 of Rule 108, which require, among others: the impleading of the civil registrar and all persons who have or claim an interest affected by the correction; the fixing of hearing schedules by order; and publication of the order once a week for three consecutive weeks. It also required that persons with interests under the entry may file opposition within fifteen days from notice or the last date of publication.

While the civil registrar was impleaded, the Court held that Eduardo failed to show that he exerted earnest efforts to bring all possible interested parties into the proceedings. It underscored that both of Eduardo’s parents were already dead, so they could no longer be impleaded. However, the Court noted that other interested persons could still exist, including Eduardo’s siblings, their descendants, and the purported Chinese wife of his father. The Court ruled that Eduardo’s generic allegation that he was impleading “all persons who shall be affected” did not satisfy the requirement of Section 3 of Rule 108. Even assuming substantial compliance could be argued on notice and publication, the Court concluded that it could not grant the reliefs sought because the required parties were not properly brought before the trial court.

Disposition and Limited Remission

Given the procedural defect in the petition’s conformity with Rule 108 requirements for substantial corrections, the Court ordered the CA Decision dated April 20, 2015 and the CA Resolution dated October 13, 2015 set aside. It then dismissed Eduardo’s Rule 108 petition for correction of entries and cancellation of annotation in the COLB, without prejudice.

The Court clarified, however, that Eduardo was not permanently barred from seeking the surname correction. It held that the dismissal was without prejudice to filing another Rule 108 petition limited to modifying Eduardo’s surname from “Cu” to “Santos,” consistent with Alanis III v. Court of Appeals, where a legitimate child was allowed to use th
