G.R. No. 78903 - Spouses Dalion vs. Court of Appeals

Petitioner: Restituta Leonardo, the only legitimate child of the late spouses Tomasina Paul and Balbino Leonardo.
Private respondents: Illegitimate children of Tomasina Paul and Jose Sebastian—Teodoro, Vicente, Corazon, Piedad, heirs of Eduvigis and Dominador (Eduardo S. Tenorlas et al., Napoleon Sebastian et al.), Evelyn, Aurora, and Julieta Sebastian.

On June 24, 1988, private respondent Corazon Sebastian, her niece Julieta Sebastian, and another companion brought to petitioner’s house an English‐language deed of partition covering the estate of Tomasina Paul and Jose Sebastian. Petitioner, who only understood Pangasinan, insisted on waiting for her husband, Jose Ramos, to translate the document. Corazon assured her that her legitime share was fully provided and induced her to sign without reading or translating.
No copy of the deed was left with petitioner. Only upon engaging counsel did she discover that her allotted share was 7,671.75 sq.m.—far less than her one‐half legitime (19,282.5 sq.m.).

July 1988: Petitioner filed a complaint in the RTC of San Carlos City for declaration of nullity of the extrajudicial settlement. Respondents pleaded lack of cause of action and asserted voluntary, explained execution before MTC Judge Austria.
February 22, 1993: RTC dismissed petitioner’s complaint and respondents’ counterclaim, ruling no duress or fraud was proven and that the proper remedy was reformation, not nullity. By obiter dictum, it noted petitioner’s legitime exceeded her allotment.
May 23, 1996: The Court of Appeals affirmed the RTC decision.
September 13, 2004: The Supreme Court granted petitioner’s Rule 45 petition for review on certiorari.

Whether petitioner’s consent to the extrajudicial settlement was given voluntarily, i.e., free from vitiating circumstances (mistake, fraud, intimidation, or undue influence).
