G.R. No. L-6163, March 14, 1912
SON CUI, TAN CHUI TOO, ET AL., plaintiffs-appellants, vs. ATANASIA GUEPANGCO Y LIM, LUISA TAN TUNGCO Y GUEPANGCO, ET AL., defendants-appellees.

FACTS

Fernando Roxas Tan Tungco, a Chinese national, died in Amoy, China, in 1892, leaving a will executed in 1891. The plaintiffs, Son Cui (claiming to be his first wife married in China in 1868) and her sons (Tan Chui Too, Tan Coco, and Tan Sioco), filed an action against the defendants, Atanasia Guepangco (Tan Tungco’s Filipina wife married in the Philippines around 1871) and her children. The plaintiffs sought to annul the will, claiming that under Chinese law, they are the only legitimate heirs entitled to Tan Tungco’s entire estate, valued at approximately P700,000. They alleged that the defendants, as a mistress and illegitimate children, are not entitled to any share. The defendants countered that Tan Tungco had established domicile in the Philippines, married Atanasia lawfully, and that the plaintiffs are, at best, unrecognized illegitimate children with no right to the estate beyond what the will provided. The trial court ruled in favor of the defendants.

ISSUE

Whether the plaintiffs have successfully proven the existence of a prior marriage between Tan Tungco and Son Cui in China, thereby establishing their status as legitimate heirs entitled to inherit from Tan Tungco’s estate to the exclusion of the defendants.

RULING

No. The Supreme Court affirmed the trial court’s decision, holding that the plaintiffs failed to prove the alleged prior marriage in China by the requisite preponderance of evidence. The Court found the evidence presented by the plaintiffs (witness testimony and a marriage contract from China) to be insufficient and unreliable, especially when weighed against the contrary evidence presented by the defendants. The defendants’ evidence showed that Tan Tungco arrived in the Philippines at age 11 in 1853 and likely did not return to China until 1872, making a marriage in China in 1868 improbable. Crucially, the Court gave significant weight to Tan Tungco’s own last will and testament, wherein he expressly recognized Atanasia as his wife and her children as his only legitimate heirs, with no mention of Son Cui or her children. Following the precedent in Sy Joc Lieng vs. Sy Quia, the Court emphasized the difficulty of rebutting claims of a foreign marriage and the importance of strong, credible evidence to overturn the facts stated in a duly executed will. Consequently, the plaintiffs, not having established their legitimacy, have no right to the estate beyond any provisions made for them in the will. The will, having been probated and the estate partitioned accordingly, was upheld.
