G.R. No. 149844; October 13, 2004
MIGUEL CUENCO, Substituted by MARIETTA C. CUYEGKENG, petitioner, vs. CONCEPCION CUENCO Vda. DE MANGUERRA, respondent.

FACTS

The case involves a parcel of land, Lot 903-A-6, originally part of Lot 903-A which was received as attorney’s fees by the law firm “Cuenco and Cuenco,” a partnership between brothers Mariano Jesus Cuenco and Miguel Cuenco. Mariano, who was practicing in Manila, entrusted his share, Lot 903-A, to his brother Miguel. In 1947, in anticipation of Mariano’s second marriage, the family agreed to partition Lot 903-A into six sublots for Mariano’s six children from his first marriage. Miguel executed deeds of donation for five sublots to the other five children but excluded the respondent, Concepcion Cuenco Vda. de Manguerra. Respondent occupied and fenced her designated portion, Lot 903-A-6, and paid realty taxes thereon.
After Mariano’s death, his last will and testament stated that his attorney’s fees from the relevant cases had been “disposed of, and distributed by me, through my brother, Miguel, to all my said children in the first marriage.” Despite this, Miguel subsequently sought to have Lot 903-A-6 registered in his own name, leading respondent to file an affidavit of adverse claim and, ultimately, a complaint for reconveyance.

ISSUE

Whether petitioner Miguel Cuenco holds Lot 903-A-6 under an implied trust in favor of respondent Concepcion Cuenco Vda. de Manguerra, obligating him to reconvey the property to her.

RULING

Yes, the Supreme Court affirmed the decisions of the lower courts, ruling that an implied trust existed in favor of the respondent. The legal logic is anchored on the principle against unjust enrichment and the factual circumstances establishing an implied trust under Article 1456 of the Civil Code, which provides that if property is acquired through mistake or fraud, the person obtaining it is, by operation of law, considered a trustee of an implied trust for the benefit of the true owner.
The Court found that Lot 903-A was a partnership asset of the Cuenco law firm. As partners, Mariano and Miguel were entitled to equal shares in the attorney’s fees, making Mariano the beneficial owner of one-half. The act of entrusting the title to Miguel created a fiduciary relationship. The 1947 partition plan, to which Miguel acquiesced, and the subsequent donations to five children, collectively demonstrated a clear intention to distribute the property among all six children. Miguel’s exclusion of respondent, while donating to her five siblings, was inconsistent with his claim of absolute ownership and instead confirmed he was holding the lot in trust for the designated beneficiaries. His subsequent attempt to claim sole title constituted fraud, giving rise to the implied trust. The Court held that allowing Miguel to retain the property would result in unjust enrichment at the expense of the rightful beneficiary, respondent Concepcion Cuenco Vda. de Manguerra.
