PNB vs. Mallorca

A real estate mortgage remains indivisible and attaches to the entirety of the mortgaged property irrespective of subsequent subdivisions or partial sales, binding subsequent purchasers regardless of privity with the original debtor. Consequently, a mortgagee's extrajudicial foreclosure validly consolidates title over the entire property upon the expiration of the statutory redemption period. Furthermore, a cadastral court possesses jurisdiction to order the cancellation of an outstanding duplicate certificate of title and consolidate ownership when the underlying issue of encumbrance has been definitively settled in a prior final judgment, rendering the petition incidental and devoid of substantial controversy.

Ruperta Lavilles mortgaged a 48,965-square-meter parcel of land in Passi, Iloilo to the Philippine National Bank in 1950 to secure a P1,800 loan. In 1958, Lavilles sold a 20,000-square-meter portion of the mortgaged property to Primitiva Mallorca without the bank's knowledge or consent. Mallorca petitioned the cadastral court to annotate her interest on the title, prompting the court to order the bank to surrender the owner's copy of the title for registration while explicitly noting that the mortgage lien would remain binding on any subsequent vendee. The Register of Deeds subsequently cancelled the original title and issued a new certificate with co-owner's copies for both Lavilles and Mallorca, both annotated with the bank's mortgage lien.

• The mortgage executed by Lavilles in favor of PNB covered a 48,965-square-meter lot and was duly registered in the Office of the Register of Deeds.
• Lavilles subsequently sold a 20,000-square-meter portion of the mortgaged property to Mallorca without PNB's knowledge or consent.
• Mallorca successfully moved the cadastral court to annotate her purchase on the title, resulting in the issuance of co-owner's duplicate certificates for both Lavilles and Mallorca, each carrying the annotation of PNB's mortgage lien.
• Following Lavilles' default, PNB extrajudicially foreclosed the mortgage and obtained a certificate of sale as the highest bidder.
• Mallorca initiated a separate civil action to enforce her right of redemption, which the trial court granted while dismissing her claim for damages.
• Mallorca failed to redeem the property within the period decreed by the trial court, causing the redemption period to expire.
• PNB presented the final deed of sale to the Register of Deeds for registration, but the Register refused to issue a new title in PNB's name without Mallorca's surrender of her co-owner's duplicate certificate.
• PNB filed a petition for consolidation of title in the cadastral court, seeking the nullification and cancellation of Mallorca's duplicate title.
• The cadastral court issued an order directing Mallorca to surrender her co-owner's duplicate title within five days, which Mallorca appealed to the Court of Appeals.

• Petitioner maintained that the mortgage lien is indivisible and attaches to the entirety of the mortgaged property, binding all subsequent purchasers regardless of their participation in the original loan contract.
• Petitioner argued that its extrajudicial foreclosure and the expiration of Mallorca's statutory redemption period lawfully divested her of any remaining interest in the property.
• Petitioner asserted that the cadastral court validly exercised jurisdiction over the consolidation petition because the validity of the encumbrance had already been conclusively determined in a prior final judgment, leaving no substantial controversy to resolve.

• Respondent contended that her 20,000-square-meter undivided interest remained unaffected by the foreclosure because she was not a party to the original real estate mortgage and did not contract the loan secured by PNB.
• Respondent maintained that PNB only foreclosed the portion of the property belonging to Lavilles, and therefore lacked authority to consolidate title over the portion she purchased.
• Respondent argued that the cadastral court lacked jurisdiction to entertain the petition, as the request to nullify her co-owner's copy elevated the proceedings to contentious litigation beyond the incidental powers of a cadastral court.

• Procedural Issues: Whether the Court of First Instance, sitting as a cadastral court, has jurisdiction to order the cancellation of a co-owner's duplicate certificate of title and consolidate ownership in favor of a mortgagee.
• Substantive Issues: Whether the extrajudicial foreclosure of a real estate mortgage validly extinguishes the interest of a subsequent purchaser of a portion of the mortgaged property, notwithstanding the purchaser's non-participation in the original loan agreement.

• Procedural: The Court held that the cadastral court validly exercised jurisdiction over the petition for consolidation. Because the validity of the mortgage encumbrance and the subsequent foreclosure had already been definitively resolved in a prior final judgment, the petition presented no substantial controversy. The Court ruled that a cadastral court may entertain petitions for the cancellation of outstanding titles where the registered owner has been lawfully divested, treating the matter as an incidental proceeding within the land registration case.
• Substantive: The Court ruled that PNB's foreclosure validly consolidated title over the entire mortgaged lot, including Mallorca's acquired portion. The Court grounded its decision on the indivisibility of real estate mortgages and the principle that a mortgage lien is a right in rem that follows the property irrespective of changes in ownership. The Court emphasized that registration of the mortgage constitutes constructive notice to all subsequent purchasers, and Mallorca's own co-owner's duplicate title explicitly carried the annotation of PNB's lien. Furthermore, Mallorca's failure to exercise her court-decreed right of redemption within the statutory period extinguished her remaining interest and estopped her from denying the mortgage lien.

• Indivisibility of Real Estate Mortgage — The doctrine holds that a mortgage secures the entirety of the debt and attaches to every portion of the mortgaged property, regardless of subsequent subdivisions or partial transfers. The Court applied this principle to rule that PNB's foreclosure encompassed the entire lot, binding Mallorca's acquired portion because the mortgage lien remains intact and enforceable against the whole property until the obligation is fully satisfied.
• Mortgage as a Right In Rem — A real estate mortgage directly and immediately subjects the mortgaged property to the fulfillment of the obligation, binding whoever the possessor may be, irrespective of privity of contract with the mortgagee. The Court relied on this principle to establish that subsequent purchasers are bound by existing, duly registered encumbrances, as the mortgage subsists notwithstanding changes in ownership and follows the property into the hands of transferees.

• "By Article 2126 of the Civil Code, a 'mortgage directly and immediately subjects the property upon which it is imposed, whoever the possessor may be, to the fulfillment of the obligation for whose security it was constituted.' Sale or transfer cannot affect or release the mortgage." — The Court invoked this provision to establish that the mortgage lien attaches to the property itself as a right in rem, binding subsequent purchasers regardless of their participation in the original loan contract.
• "Because the personality of the owner is disregarded; the mortgage subsists notwithstanding changes of ownership; the last transferee is just as much of a debtor as the first one; and this, independent of whether the transferee knows or not the person of the mortgagee." — This passage underscores the Court's rationale that privity of contract is unnecessary to enforce a registered mortgage against a transferee, as the encumbrance runs with the land.

• Bischoff vs. Pomar — Cited to support the principle that a registered real estate mortgage constitutes a right in rem and a lien on the property, binding whoever the owner may be.
• Goquiolay vs. Sycip — Invoked to illustrate the doctrine of mortgage indivisibility, establishing that each parcel under mortgage answers for the totality of the debt.
• E. C. McCullough & Co. vs. Veloso — Relied upon to affirm that a sale of a portion of mortgaged property cannot prejudice the mortgagee's rights, as the mortgage follows the property regardless of the transferee's status.
• Castillo vs. Ramos — Applied to resolve the jurisdictional issue, holding that a cadastral court may entertain a petition for cancellation of an outstanding title where there is no substantial controversy between the parties, treating it as a mere incidental matter in the land registration case.
• De Barretto vs. Villanueva — Cited in relation to Section 39 of the Land Registration Act, reinforcing that a subsequent purchaser takes title subject to all encumbrances explicitly noted on the certificate of title.
• Cavan vs. Wizlezenus and Alto Surety & Insurance Co. Inc. vs. Limcaco — Referenced to support the rule that a cadastral court has jurisdiction to order cancellation of a certificate of title when the registered owner has been lawfully divested of ownership.

• Article 2126, Civil Code — Defines the real nature of a mortgage, establishing that it directly subjects the property to the fulfillment of the obligation regardless of the possessor's identity.
• Article 2089, Civil Code — Provides for the indivisibility of the mortgage, mandating that the encumbrance remains intact and enforceable over the entirety of the property despite partial transfers or subdivisions.
• Section 39, Land Registration Act — Governs the rights of subsequent purchasers, stipulating that they hold title free of encumbrances only if such encumbrances are not noted on the certificate of title; conversely, noted encumbrances bind the purchaser.
• Section 51, Land Registration Act — Establishes that registration of a mortgage in the Register of Deeds serves as constructive notice to all persons regarding the existence of the encumbrance.
• Sections 111 and 112, Land Registration Act — Cited to delineate the cadastral court's authority to order the cancellation of outstanding certificates of title and consolidate ownership upon lawful divestment.
