G.R. No. 159486-88 - Estrada vs. Sandiganbayan

Case Summary (G.R. No. 159486-88)

Factual Background

The parties met in 1991 and became sweethearts. They applied for a marriage license in September 1994 but when they returned the license had expired. To proceed, they executed an affidavit dated 13 March 1995 stating they had lived together as husband and wife for at least five years; they were married the same date, with civil rites administered by Judge Jose C. Bernabe. After the ceremony the couple did not live together as husband and wife. The child at issue was born in November 1995 (records reflect both November 13 and November 3, 1995 in different documents). Since the child’s birth the respondent supported the child from her income as a dentist and private practice.

Trial Court Proceedings and Decision

On 4 June 1998 respondent filed an action for support in the RTC, alleging marriage to petitioner and assertion that petitioner reneged on his support obligations for respondent and their child. Petitioner denied the marriage’s validity, alleging the March 13, 1995 affidavit was false, that he was induced to sign the marriage contract to avoid respondent’s embarrassment and possible administrative consequences due to pregnancy, that they never cohabited as husband and wife, and that he never acknowledged the child. The RTC, in its 16 October 2000 decision, held the marriage was not valid because it was solemnized without a marriage license, but declared petitioner the natural (biological) father of the child and obliged him to provide support.

Court of Appeals Decision

The Court of Appeals reversed aspects of the RTC decision. The CA emphasized the general presumption that a marriage is subsisting until judicially declared null and that the child was born during the subsistence and validity of the parties’ marriage. The CA criticized petitioner’s refusal to undergo DNA testing and his uncertain testimony about the last time he had carnal relations with respondent, and it gave weight to an affidavit executed by petitioner on 7 April 1998 wherein he admitted paternity. The CA also held that the trial court erred in declaring the marriage null in the same support action because a declaration of nullity requires participation of the State (prosecutor) to guard against collusion as mandated by the Family Code; the CA therefore declared the child legitimate and the marriage valid until properly annulled by a competent court. The CA affirmed the RTC decision with those modifications.

Petition to the Supreme Court and Parties’ Contentions

Petitioner moved for reconsideration at the CA and thereafter filed a petition to the Supreme Court. He argued the marriage was void ab initio because the affidavit substituting for a marriage license was false and that the false affidavit should not substitute for the absence of a license. He claimed the trial court had jurisdiction to determine invalidity as an affirmative defense in the support action and invoked authority that a void marriage may be subject to collateral attack, avoiding the need for a separate declaration action. He further contended the CA erred in declaring the child legitimate. Respondent argued the petition was dilatory and reiterated that legitimacy of marriage cannot be collaterally attacked, and highlighted petitioner’s evasive testimony and refusal to submit to DNA testing. The Office of the Solicitor General (OSG) supported the RTC, arguing the marriage was solemnized without a license and the affidavit was false, thus rendering the marriage void.

Legal Issues Presented

Two primary issues were framed: (1) whether the trial court had jurisdiction to determine the validity of the marriage in an action for support; and (2) whether the child is the petitioner’s daughter (i.e., legitimacy/filiation).

Supreme Court’s Ruling on Jurisdiction and Collateral Attack

The Supreme Court held that the trial court did have jurisdiction to decide the validity of the marriage in the support action. The Court reaffirmed that the validity of a void marriage may be collaterally attacked where determination of the marriage’s validity is essential to disposition of the case. The Court referenced Nia‑al v. Bayadog and Nicdao Cariño v. Yee Cariño for the principle that courts may pass upon validity of a marriage in a suit not directly instituted to annul it when it is necessary to resolve issues such as legitimacy, heirship, settlement of estate, or support claims. The Court emphasized that while a final judgment of declaration of nullity may be necessary when required by subsequent purposes, preliminary or collateral adjudication of voidness is permissible when essential to the case’s determination.

Supreme Court’s Analysis on Merits — Marriage Validity under Family Code Article 34

Applying Family Code Article 34, which dispenses with a marriage license for couples who have continuously cohabited as husband and wife for at least five years provided the parties state these facts in an affidavit, the Court examined the affidavit executed in lieu of a license. The Court found the affidavit false: the parties did not cohabit for five continuous years and respondent herself admitted under cross‑examination that she had not been living with petitioner as husband and wife for the relevant period before March 13, 1995. The Court stressed that Article 34’s purpose is to protect persons who have been publicly and scandalously cohabiting; where there was no such cohabitation the exemption cannot be invoked. Consequently, the false affidavit could not cure absence of the marriage license and had “no val

Facts of the Case

Petitioner and respondent met and became sweethearts in 1991 and planned to marry; they applied for a marriage license with the Office of the Civil Registrar of Pasig City in September 1994.
The couple had their first sexual relation in October 1994 and engaged in sexual relations regularly thereafter.
When they returned to obtain a marriage license, the previously applied-for license had already expired.
To proceed with the planned marriage, they executed an affidavit dated 13 March 1995 stating that they had been living together as husband and wife for at least five years.
The couple was married on 13 March 1995, with Judge Jose C. Bernabe, presiding judge of the Metropolitan Trial Court of Pasig City, administering the civil rites.
After the ceremony, petitioner and respondent returned to their respective homes and did not live together as husband and wife.
On 13 November 1995 (appearing elsewhere in the record as November 3, 1995), respondent gave birth to a child named Reinna (or Reianna/Reianna Tricia/REIANNA TRICIA A.) De Castro.
Since the child’s birth, respondent allegedly has supported the child from her income as a government dentist and from her private practice.
On 4 June 1998, respondent filed a complaint for support against petitioner before the Regional Trial Court of Pasig City (case later raffled to Branch 70, presided by Judge Pablito M. Rojas).
Petitioner denied marriage and paternity/filiation, alleging the marriage was void ab initio because it was facilitated by a fake affidavit, that he was prevailed upon to sign the marriage contract, that they never lived together as husband and wife, and that he had never seen nor acknowledged the child.

Procedural History

Trial court (Regional Trial Court, Branch 70, Pasig City) rendered a Decision dated 16 October 2000:
- Held the marriage between petitioner and respondent not valid because it was solemnized without a marriage license.
- Declared petitioner as the natural father of the child and obliged him to provide support.
Petitioner appealed to the Court of Appeals (CA-GR CV No. 69166).
The Court of Appeals denied petitioner’s appeal and issued a decision that: (1) declared Reianna Tricia A. De Castro the legitimate child of the petitioner; and (2) declared the marriage valid until properly nullified by a competent court in a proceeding instituted for that purpose. Costs were assessed against the appellant.
Petitioner filed a motion for reconsideration with the Court of Appeals which was denied.
Petitioner elevated the matter to the Supreme Court by petition for review. The Court of Appeals’ Decision and Resolution were the subjects of the petition.
The Office of the Solicitor General (OSG) and respondent filed comments as directed by the Supreme Court.

Issues Presented

Whether the trial court had jurisdiction to determine the validity of the marriage between petitioner and respondent in an action for support.
Whether the child is the daughter of petitioner (i.e., issues of paternity and filiation and petitioner’s obligation to support).

Trial Court Ruling (16 October 2000)

The trial court ruled the marriage between petitioner and respondent was invalid because it was solemnized without a marriage license.
Despite declaring the marriage invalid, the trial court declared petitioner as the natural father of the child and ordered him to provide support.
The trial court relied on testimonial and documentary evidence including the parties’ conduct and admissions and photographic exhibits depicting the marriage ceremony.

Court of Appeals Decision (CA-GR CV No. 69166)

The Court of Appeals affirmed with modifications:
- Declared Reianna Tricia A. De Castro as the legitimate child of the appellant and appellee.
- Declared the marriage on 13 March 1995 between appellant and appellee valid until properly annulled by a competent court in a proceeding instituted for that purpose.
Reasoning and key points by the Court of Appeals:
- Emphasized the rule that a marriage is presumed to be subsisting until a judicial declaration of nullity is made; thus the child was born during the subsistence and validity of the marriage.
- Criticized petitioner’s refusal to undergo DNA testing and petitioner’s uncertainty regarding the last time he had carnal knowledge with respondent; described petitioner’s forgetfulness as insufficient ground to relieve him of obligation.
- Noted petitioner’s affidavit dated 7 April 1998 wherein he voluntarily admitted he is the legitimate father of the child.
- Held that it was improper for the trial court to declare the marriage null and void in an action for support because the participation of the State (prosecuting attorney/fiscal) is required in annulment actions to ensure absence of collusion, per Family Code requirements.
- Concluded that the issue of nullity should have been raised in a direct action for declaration of nullity rather than in the support proceedings.

Petitioner’s Contentions Before the Supreme Court

Petitioner maintained that the trial court properly annulled his marriage because the marriage was celebrated without a marriage license and the affidavit executed in lieu of a license contained false facts — specifically, that they had been living together for five years when in truth they had not.
He argued the false affidavit should not be allowed to substitute for the absence of a marriage license.
Petitioner contended that the appearance of a prosecuting attorney was unnecessary because the action was one for support, not for annulment or declaration of absolute nullity.
He argued that the trial court had jurisdiction to determine invalidity as an affirmative defense in the action for support and cited authorities to support that a void marriage can be the subject of a collateral attack rather than requiring a separate direct proceeding.
Petitioner stressed practical considerations against requiring a separate suit for nullity, including expense, anxiety, delay, and increased court burden.
