Case Summary (G.R. No. 183852)

Factual Background

Pacifico Brobio died intestate, leaving three parcels of land. On May 12, 2002, his heirs executed a Deed of Extrajudicial Settlement with Waiver in which petitioner and other children waived their shares in the three parcels in favor of respondent in consideration of P150,000 and affection. Petitioner alleged that respondent promised an additional amount for her share. While respondent was processing BIR requirements, she lacked an original copy of the Deed and requested petitioner to countersign a duplicate on May 31, 2003. Petitioner refused to sign unless respondent gave the promised additional payment. After bargaining (petitioner initially demanded P1,000,000 and respondent asked for a reduction), the parties agreed to P600,000. Because respondent lacked cash at the time, she executed a promissory note dated May 31, 2003 promising to pay P600,000 on June 15, 2003; petitioner countersigned the deed only after respondent executed the note. Respondent did not pay when the note matured and refused repeated demands.

Procedural History

Petitioner filed a Complaint for Specific Performance with Damages on January 28, 2004. The RTC rendered judgment for petitioner on May 15, 2006, ordering payment of P600,000 plus 12% interest from filing date, attorney’s fees of P50,000, and costs. The CA reversed the RTC and dismissed the complaint on February 21, 2008, finding the promissory note lacked consideration and was executed under intimidation. The CA denied petitioner’s motion for reconsideration on July 9, 2008. Petitioner sought review by the Supreme Court, which reinstated the RTC decision and reversed the CA on the issues presented.

Issues Presented on Review

The petition identified three principal issues: (1) whether intimidation or other vitiating factors attended the execution of the promissory note; (2) whether the promissory note was supported by consideration; and (3) whether an action for partition, rather than specific performance, should have been the remedy.

RTC Findings and Rationale

The RTC found no undue influence or intimidation vitiating respondent’s consent. It characterized the promissory note as the product of negotiation and concluded that respondent acted in bad faith by executing a written promise she did not intend to honor. The trial court also concluded that the promissory note constituted additional consideration for petitioner’s waiver of her share and therefore imposed liability on respondent for P600,000 plus interest, attorney’s fees, and costs.

Court of Appeals Findings and Rationale

The CA concluded that the promissory note was without consideration and therefore had no legal force. It reasoned that the extrajudicial settlement already effected the waiver in 2002 and petitioner had received P150,000; consequently, the later promissory note could not be supported by the earlier settlement as consideration. The CA characterized the promissory note as a device to secure petitioner’s signature to satisfy a BIR requirement — and thus as induced by intimidation or compulsion. The CA further stated that, if petitioner claimed inadequacy of the P150,000, she should have pursued partition instead of specific performance.

Supreme Court Legal Standards on Consent and Undue Influence

The Supreme Court reaffirmed that contracts are voidable when consent is vitiated by mistake, violence, intimidation, undue influence, or fraud. The court emphasized the wide latitude afforded trial courts in weighing surrounding circumstances, including the parties’ ages, relationship, conduct, and intelligence. It reiterated the statutory definitions and tests: undue influence exists when one takes improper advantage of power over another’s will, depriving that person of reasonable freedom of choice; for undue influence to vitiate consent, the influence must have so overpowered or subjugated the mind that the party expressed another’s will instead of his or her own (Civil Code Art. 1337 and related jurisprudence cited in the decision).

Supreme Court Conclusion on Undue Influence and Intimidation

Applying these standards, the Court found no evidence that respondent was deprived of free agency when she signed the promissory note. The record showed bargaining over the amount (from P1,000,000 to P600,000) and respondent’s own testimony that she negotiated and personally wrote the P600,000 amount. The Court explained that being compelled by circumstance (need to comply with BIR requirements) does not automatically equate to vitiated consent; intimidation requires a reasonable and well‑grounded fear of imminent and grave evil upon person or property, which was not shown. Potential penalties for late BIR submission did not constitute the kind of imminent grave evil necessary to invalidate consent.

Supreme Court Analysis on Consideration

The Court applied the presumption that contracts have cause or consideration (Civil Code Art. 1354) and held that mere assertion of lack of consideration is insufficient to overcome this presumption; the party alleging lack (here, respondent) bears the burden of proving absence of consideration by a preponderance of evidence. The Supreme Court found that consideration existed at least in the form of petitioner’s signature on the Deed, i.e., petitioner’s agreement to sign the document was the quid pro quo for the promissory note. Even if such consideration were inadequate, inadequacy alone does not invalidate a contract unless accompanied by fraud, mistake, or undue influence — none of which were proved.
