San Pedro vs. Ong

In a quasi in rem action for quieting of title, jurisdiction over the res is sufficient for the court to hear and decide the case; invalid service of summons on a defendant does not void the entire proceeding but merely precludes a valid judgment regarding that defendant's personal liability. Additionally, a mortgagee who deals with an agent rather than the registered owner must exercise a higher degree of diligence to ascertain the agent's authority, and failure to do so precludes a claim of good faith.

Petitioner Robert San Pedro purchased two parcels of land from the Spouses Narciso and hired Adora Dela Peña to facilitate the transfer of the titles. Dela Peña fraudulently procured Special Powers of Attorney (SPAs) from the Spouses Narciso—bearing forged and spurious signatures—and used them to mortgage the properties to respondent Willy Ong through Ong's agent, Normita Caballes. Upon discovering the encumbrance, San Pedro filed a petition for nullification of mortgage with damages.

• Purchase and Encumbrance: San Pedro bought two parcels of land from the Spouses Narciso, paid ₱35,000.00, and took possession, building a house worth ₱2,000,000.00. He hired Dela Peña to transfer the titles. Instead, Dela Peña procured SPAs from the Spouses Narciso through misrepresentation and fraud, then mortgaged the properties to Ong for ₱170,000.00 through Ong’s agent, Caballes.
• Discovery of Fraud: Upon inquiry, San Pedro found the properties still registered in the Spouses Narciso’s names and mortgaged to Ong. The Spouses Narciso denied authorizing the mortgage. An NBI handwriting expert confirmed that Guillermo Narciso’s signature on one SPA was forged and Brigida Santiago’s signatures on both SPAs were spurious.
• RTC Proceedings: San Pedro filed a Petition for Nullification of Mortgage. Summons was served on Dela Peña via substituted service (left with her sister-in-law who refused to sign). Dela Peña was declared in default. The Spouses Narciso admitted the sale but denied the mortgage. Ong and Caballes claimed to be mortgagees in good faith, relying on the SPAs and clean titles. The RTC ruled in San Pedro's favor, declaring the mortgages void.
• CA Reversal: Ong and Caballes appealed, arguing the RTC lacked jurisdiction over Dela Peña due to invalid substituted service. The CA agreed, holding Dela Peña was an indispensable party and the invalid service voided the entire proceedings, resulting in a remand.

• Jurisdiction over the Res: San Pedro maintained that the action for quieting of title is quasi in rem, requiring only jurisdiction over the subject property, which the RTC acquired upon the filing of the petition.
• Indispensable Party: San Pedro argued that Dela Peña was not an indispensable party, as the core issue was the validity of the mortgage and the superiority of his title over Ong's, making her presence unnecessary for a complete determination of the main controversy.
• Mortgagee in Good Faith: San Pedro asserted that Ong was not a mortgagee in good faith because Ong failed to exercise the required degree of diligence in verifying Dela Peña's authority, having never personally met Dela Peña or the Spouses Narciso.

• Jurisdiction over Dela Peña: Respondents countered that the RTC lacked jurisdiction over Dela Peña because the substituted service of summons was invalid, rendering the entire proceedings fatally defective.
• Indispensable Party: Respondents maintained that Dela Peña was an indispensable party without whom no final determination of the case could be had, given her central role in procuring the SPAs and the loan.
• Mortgagee in Good Faith: Respondents argued that Ong was a mortgagee in good faith who relied on the facial validity of the SPAs and the clean titles of the properties verified by Caballes at the Registry of Deeds.

• Jurisdiction: Whether the RTC acquired jurisdiction to hear and decide the case despite the invalid substituted service of summons on Dela Peña.
• Indispensable Party: Whether Dela Peña is an indispensable party to the action for quieting of title.
• Good Faith: Whether Ong is a mortgagee in good faith.

• Jurisdiction: Jurisdiction was properly acquired by the RTC. An action for quieting of title is quasi in rem, where jurisdiction over the person of the defendant is not a prerequisite provided the court acquires jurisdiction over the res. The RTC acquired jurisdiction over the subject properties upon the institution of the action. The invalid service of summons on Dela Peña merely infringed her right to due process, precluding the RTC from rendering a valid judgment regarding her personal liability, but did not void the entire proceedings.
• Indispensable Party: Dela Peña was not an indispensable party. The crux of the controversy was the title of San Pedro vis-à-vis that of Ong. Dela Peña never claimed title to the properties and her interest ended after fraudulently securing the loan. Her presence would merely permit complete relief regarding her liability for damages, which can be pursued in a separate action.
• Good Faith: Ong was not a mortgagee in good faith. A higher degree of diligence is required when dealing with an agent rather than the registered owner. Ong merely relied on Caballes's representations and the facial validity of the SPAs without personally verifying Dela Peña's authority or meeting the registered owners. Mortgages based on forged SPAs are void ab initio.

• Quasi in rem jurisdiction — In actions quasi in rem, jurisdiction over the person of the defendant is not a prerequisite to confer jurisdiction on the court, provided the latter has jurisdiction over the res. Jurisdiction over the res is acquired either by seizure of the property under legal process or by the institution of legal proceedings. Service of summons in such actions is merely to satisfy due process requirements, not to vest the court with jurisdiction.
• Indispensable parties — An indispensable party is one whose interest will be affected by the court's action and without whom no final determination can be had. A party is not indispensable if their interest is distinct and divisible from the other parties and will not necessarily be prejudiced by a judgment that does complete justice to the parties in court.
• Mortgagee in good faith — While a buyer from the registered owner need not look behind the certificate of title, one who deals with an agent is put upon inquiry and must discover the agent's authority at their peril. A higher degree of diligence is required of a mortgagee when the mortgagor is not the registered owner of the property. Ignoring a significant fact that should create suspicion precludes a claim of good faith.

• "In an action in rem or quasi in rem, jurisdiction over the person of the defendant is not a prerequisite to confer jurisdiction on the court, provided that the latter has jurisdiction over the res. Jurisdiction over the res is acquired either (a) by the seizure of the property under legal process, whereby it is brought into actual custody of the law; or (b) as a result of the institution of legal proceedings, in which the power of the court is recognized and made effective. The service of summons or notice to the defendant is not for the purpose of vesting the court with jurisdiction but merely for satisfying the due process requirements."
• "While one who buys from the registered owner does not need to look behind the certificate of title, one who buys from one who is not the registered owner is expected to examine not only the certificate of title but all factual circumstances necessary for [one] to determine if there are any flaws in the title of the transferor, or in [the] capacity to transfer the land."

• Alba v. Court of Appeals, G.R. No. 164041 (29 July 2005) — Followed. Elucidated that in quasi in rem proceedings, jurisdiction over the res suffices, and service of summons is merely for due process, not jurisdiction.
• Philippine National Bank v. Heirs of Estanislao Militar and Deogracias Militar, G.R. No. 164801 (18 August 2005) — Followed. Defined indispensable parties and established that a party with a distinct and divisible interest is not indispensable.
• Abad v. Guimba, G.R. No. 157002 (29 July 2005) — Followed. Enunciated the principle that a higher degree of diligence is required when dealing with an agent rather than the registered owner.
• Bank of Commerce v. San Pablo, Jr., G.R. No. 167848 (27 April 2007) — Followed. Reiterated that a person dealing with an agent must discover the agent's authority at their peril, and deliberate ignorance of suspicious facts precludes good faith.
• Veloso and Rosales v. La Urbana, 58 Phil. 681 (1933) — Followed. Established that forged powers of attorney are without force and effect, nullifying mortgages constituted on the strength thereof.

• Article 476, Civil Code — Defines an action to quiet title, allowing the removal of a cloud upon title caused by an encumbrance or proceeding that is apparently valid but actually invalid. Applied to classify San Pedro's action as one for quieting of title, which is quasi in rem.
• Section 6, Rule 14, Revised Rules of Court — Prescribes the mode of service of summons for actions in personam. Distinguished from the rule in quasi in rem actions where jurisdiction over the res is the primary prerequisite.
