THE AI-ASSISTED CRITIQUE
The trial court’s reliance on expert testimony to infer a defect in the simultaneity of execution was a fundamental error, as the Supreme Court correctly identified that the core issue was one of credibility of witnesses. The lower court improperly substituted physical inferences—such as paper texture, ink penetration, and typewriter alignment—for a direct assessment of the attesting witnesses’ unimpeached testimony regarding the signing ceremony. This approach contravenes the principle that the best evidence of due execution is the positive, consistent testimony of the subscribing witnesses themselves, especially when, as here, the will’s language was known to the testator and the witnesses’ signatures were genuine. The trial court’s factual findings are thus not entitled to the usual deference, as they were not based on observing demeanor but on rejecting credible oral evidence in favor of speculative res ipsa loquitur conclusions drawn from the document’s physical state.

The Supreme Court properly emphasized that the relationship of the attesting witnesses to the beneficiary does not, per se, discredit their testimony, especially when contrasted with the clear interest of the oppositors as intestate heirs. The legal standard under the statute then in force, Section 618 of Act No. 190 , requires only that witnesses be “credible,” not disinterested. The Court’s reasoning that a testator might logically choose relatives of a beneficiary to ensure their cooperation is a pragmatic recognition of human behavior that does not undermine the statutory formalities. Furthermore, the presence of another legatee unrelated to the witnesses negates any inference of a conspiracy to fabricate the entire execution event, strengthening the probative value of their unanimous account against the interested, uncorroborated testimony of a single oppositor.

Ultimately, the decision safeguards the testamentary intent against defeat by hyper-technical and conjectural objections. By prioritizing the credible, affirmative evidence of execution over expert speculation about the sequence of typing and signing, the Court upheld the presumption of regularity in the notarized will’s execution. This ruling serves as a crucial check on lower courts, instructing that the formal requirements of attestation are satisfied by the witnesses’ presence and signing as described, not by forensically perfect document creation. The Court’s rejection of the “crumpled paper” theory as proof of revocation or irregularity correctly focuses on the substance of the execution ceremony over ambiguous physical clues, ensuring that a testator’s last wishes are not invalidated by inconclusive de minimis irregularities.
