Robles vs. Court of Appeals

The Court held that a co-owner who mortgages property without clearly repudiating the co-ownership only alienates his undivided share, and a bank that fails to exercise due diligence in ascertaining the title to unregistered land is a mortgagee in bad faith whose mortgage does not prejudice the other co-owners. Furthermore, a free patent issued over private land is void ab initio, and the true owner in possession may bring an action for quieting of title without need for the Office of the Solicitor General to intervene.

Leon Robles possessed a parcel of land in Morong, Rizal, declaring it for taxation purposes as early as 1916. Upon his death, his son Silvino inherited the property, and upon Silvino's death in 1942, Silvino's widow and children—petitioners Lucio, Emeteria, Aludia, Emilio, and half-brother Hilario—inherited the property. The petitioners cultivated the land and built a nipa hut, while entrusting the payment of land taxes to Hilario. In 1962, the tax declaration was transferred to Exequiel Ballena, Hilario's father-in-law. Ballena mortgaged the property to the Antipolo Rural Bank, which foreclosed and had the tax declaration transferred to its name. In 1966, Ballena sold the property to Hilario and his wife, who then mortgaged it to the Rural Bank of Cardona, Inc. Upon their default, the bank foreclosed, acquired the property at auction in 1968, and sold it to Spouses Vergel and Ruth Santos in 1987. The Santos spouses subsequently obtained Free Patent No. IV-1-010021 and took possession of the property in 1988.

• Original Ownership and Possession: Leon Robles possessed the 9,985-square-meter land in Morong, Rizal, since 1916, paying taxes thereon. He was succeeded by his son Silvino, and upon Silvino's death in 1942, by Silvino's heirs.
• Co-ownership and Delegation: Petitioners Lucio, Emeteria, Aludia, and Emilio Robles occupied the land, cultivated it, and shared its fruits. They entrusted the payment of land taxes to their half-brother, Hilario Robles.
• Irregular Tax Transfers: In 1962, the tax declaration was transferred to Exequiel Ballena (Hilario's father-in-law) without any deed of conveyance from the heirs of Silvino. Ballena mortgaged the property to the Antipolo Rural Bank, resulting in foreclosure and transfer of the tax declaration to the bank.
• Mortgage and Foreclosure: On November 7, 1966, Ballena executed a Deed of Absolute Sale in favor of Hilario and Andrea Robles. Twelve days later, the Robles spouses mortgaged the property to the Rural Bank of Cardona, Inc. to secure a loan. Upon default, the bank foreclosed, purchased the property at auction in October 1968, and consolidated its ownership.
• Sale to Santos Spouses and Free Patent: On September 25, 1987, the bank sold the property to Spouses Vergel and Ruth Santos. The Santos spouses took possession on May 10, 1988, and secured Free Patent No. IV-1-010021 in their names.
• Discovery and Ouster: Petitioners discovered the mortgage in September 1987, attempted to redeem the property unsuccessfully, and were ousted from possession in 1988.

• Petitioners maintained that they retained title to the property based on their open, continuous, and adverse possession since 1916.
• Petitioners argued that they did not agree to the real estate mortgage constituted by Hilario, and as co-owners, their shares should not be prejudiced by his actions.
• Petitioners contended that Hilario did not clearly repudiate the co-ownership, as he did not exclude them from the property and they continued to share in its fruits.
• Petitioners insisted that the free patent was void because the property had already become private land through prescription.

• Respondent Santos spouses traced their claim from Exequiel Ballena to Hilario and Andrea Robles, who mortgaged the property as absolute owners, and subsequently to the bank's foreclosure sale.
• Respondents argued that petitioners lost their title due to the transfers of the tax declarations to Ballena, the bank, and Hilario.
• Respondents contended that prescription had set in because Hilario's acts of possessing the property and declaring it for taxation in his name repudiated the co-ownership, and petitioners were inactive for over 20 years.
• Respondents asserted that the real estate mortgage was valid, being a public document with a presumption of due execution, and that Hilario's judicial admission of ownership was binding.
• Respondents maintained that only the Office of the Solicitor General could file an action to nullify a free patent.

• Procedural Issues:
  • Whether petitioners have the legal personality to question the validity of the free patent, or whether such action must be filed exclusively by the Office of the Solicitor General.
• Substantive Issues:
  • Whether petitioners possess the requisite legal or equitable title to maintain an action for quieting of title.
  • Whether the real estate mortgage executed by Hilario Robles is valid and binding upon the shares of the other co-owners.
  • Whether Free Patent No. IV-1-010021 issued to the Santos spouses is valid.

• Procedural: The Court ruled that petitioners have the legal personality to question the free patent. The rule that only the Solicitor General may file actions for cancellation of free patents applies only when the land is recognized as part of the public domain and the ultimate beneficiary of the cancellation would be the government. Because petitioners asserted and proved private ownership over the disputed parcel, the action did not seek reversion to the State but recognition of their private right.
• Substantive: The Court held that petitioners possessed the requisite title to maintain the action for quieting of title. Their open, continuous, exclusive, and notorious possession since 1916 vested private ownership by operation of law (acquisitive prescription). The Court ruled that the real estate mortgage was void insofar as it prejudiced the shares of the petitioners. Hilario Robles was not the absolute owner of the entire property but a mere co-owner; a co-owner may only alienate his undivided share. The Rural Bank of Cardona, Inc. was a mortgagee in bad faith because it failed to observe due diligence in ascertaining the title to the unregistered land. Had it been circumspect, it would have discovered the petitioners in actual possession. Finally, the Court declared the free patent null and void. Because the property had already become private land through the petitioners' possession for over 30 years, it was beyond the jurisdiction of the Director of Lands. A free patent issued over private land produces no legal effect.

• Repudiation of Co-ownership — For a co-owner to acquire the shares of other co-owners by prescription, the following requisites must concur: (1) the co-owner has performed unequivocal acts of repudiation amounting to an ouster of the other co-owners; (2) such positive acts of repudiation have been made known to the other co-owners; and (3) the evidence thereof is clear and convincing. The Court held that Hilario's execution of a mortgage and payment of taxes did not constitute repudiation, as he did not exclude the petitioners from possession or enjoyment of the fruits.
• Due Diligence of Banks in Unregistered Land — Banks must exercise more care and prudence in dealing with unregistered lands than private individuals, as their business is affected with public interest. They cannot rely solely on tax declarations or unnotarized deeds; they must ascertain the true owners and possessors. The Court held the Rural Bank of Cardona, Inc. was a mortgagee in bad faith for failing to investigate the actual possessors of the land.
• Free Patent over Private Land — A free patent issued over private land is null and void ab initio and produces no legal effect. The Director of Lands has no authority to grant a free patent for land that has ceased to be public land and has passed to private ownership. The nullity arises not from fraud, but from lack of jurisdiction.

• "Unless the co-ownership is clearly repudiated, a co-owner cannot, by prescription, acquire title to the share of the other co-owners."
• "Buyers of unregistered real property, especially banks, must exert due diligence in ascertaining the titles of mortgagors and sellers, lest some innocent parties be prejudiced."
• "A free patent which purports to convey land to which the government did not have any title at the time of its issuance does not vest any title in the patentee as against the true owner."
• "Quod nullum est, nullum producit effectum."

• Rural Bank of Compostela v. Court of Appeals, 271 SCRA 76 (1997) — Cited as controlling precedent holding that the rule allowing reliance solely on certificates of title does not apply to banks, which must exercise more care and prudence.
• Agne v. Director of Lands, 181 SCRA 793 (1990) — Followed for the proposition that the Director of Lands has no authority to grant a free patent over private land, and such a patent is void.
• Heirs of Marciano Nagano v. Court of Appeals, 282 SCRA 43 (1997) — Followed for the ruling that a free patent issued over private land is void and gives the true owner a cause of action for quieting of title which is imprescriptible, and that the true owner need not rely on the Solicitor General to file the action.
• Peltan Development, Inc. v. Court of Appeals, 270 SCRA 82 (1997) — Distinguished. The Court clarified that while Peltan held only the Solicitor General could file for cancellation of a free patent, that rule applies only when the land is public and reversion to the State is sought, not when private ownership is asserted.

• Article 476, Civil Code — Defines an action to quiet title as a remedy for the removal of any cloud or doubt on title to real property. Applied to determine if petitioners could seek the removal of the free patent and mortgage.
• Article 477, Civil Code — Requires the plaintiff in a quieting of title action to have legal or equitable title to or interest in the real property. Applied to assess whether petitioners, as co-owners in possession, possessed the requisite title.
• Article 493, Civil Code — Provides that each co-owner has full ownership of his part and may alienate or mortgage it, but the effect is limited to the portion allotted upon termination of co-ownership. Applied to limit the effect of Hilario's mortgage to his undivided share.
• Article 2085(2), Civil Code — Requires that the mortgagor be the absolute owner of the thing mortgaged. Applied to invalidate the mortgage as to the shares of the petitioners, since Hilario was not the absolute owner of the entire property.
• Article 1137, Civil Code — Provides that ownership and other real rights over immovables prescribe through uninterrupted adverse possession for thirty years without need of title or good faith. Applied to establish that the property had become private land, segregated from the public domain.
• Act No. 2874 (Public Land Act) — Limits the jurisdiction of the Director of Lands to public lands. Applied to render the free patent void for having been issued over private land.
