Coso vs. Deza
Case
G.R. No. 16763
Decision Date
Dec 22, 1921
A testator's will, favoring his illegitimate son and mistress, was upheld as valid; undue influence claims were unproven, preserving his free agency.

Case Summary (G.R. No. 16763)

Background and Facts

The case involves an appeal from the Court of First Instance of Manila which annulled a will on the grounds of undue influence. The will granted the “tercio de libre disposición” — one-third of the testator's estate subject to his free disposal — to an illegitimate son born from the testator's illicit relationship with Rosario Lopez. The will also directed payment of 1,900 Spanish duros to Rosario Lopez as reimbursement for expenses she incurred while caring for the testator during his prolonged illness in Barcelona between 1909 and 1916. The testator, who was married and a resident of the Philippines, had a long-standing extramarital relationship with Lopez, which began in Spain in 1898 and continued until his death in Manila in 1919. After his return to the Philippines, Lopez followed him and maintained close contact until he died.

Issue

The principal issue is whether the influence Rosario Lopez exerted on the testator was “undue” to the extent of invalidating the will. Specifically, whether her influence destroyed the testator’s free agency so that the will represented the influence of another rather than the testator’s own intent.

Applicable Legal Principles on Undue Influence

The Court applied prevailing English and American jurisprudence on undue influence, as articulated in 40 Cyc., which mandates that:

  • Mere influence or affection over a testator does not suffice to invalidate a will; the influence must be “undue.”
  • “Undue influence” is influence of such a nature that it subjugates the testator’s mind, destroying free agency and causing him to express the will of another rather than his own.
  • The influence must be exerted at or near the time of executing the will with the specific objective of procuring testamentary dispositions benefiting particular parties.
  • The burden to prove undue influence rests on those challenging the will.
  • Influence exerted by a person occupying a morally improper or adulterous relationship might be more readily scrutinized; however, influence alone—even in such a context—does not vitiate a will unless free agency is lost.

Findings of the Court

The Court found that while Rosario Lopez did exercise some influence over the testator and the testator expressed strong affection for her, there was insufficient evidence that this influence destroyed his capacity for free will in making the will. The testator:

  • Was intelligent, a lawyer by profession, and capable of knowing and expressing his own mind.
  • Likely acted out of a legitimate sense of duty to provide for an illegitimate child.
  • Seemed to have a genuine feeling of gratitude towards Lopez for her care and sacrifices, justifying reimbursement.

The Court noted that affection—illegitimate or otherwise—does not equate to undue influence. Nor was there proof of fraud, imposition, or coercion sufficient to vitiate the will. The rule that influence gained by kindness and affection, without fraud or oppression, will not invalidate a voluntarily made testamentary disposition was also emphasized, citing Mackall v. Mackall, 135 U.S. 167.
