G.R. No. 175816 - BPI Family Savings Bank, Inc. vs. Ma. Arlyn T. Avenido and Pacifico A. Avenido

Petitioner BPI Family Savings Bank (BPI Family) filed a Complaint for Collection of Deficiency of Mortgage Obligation with Damages against respondents spouses Pacifico A. Avenido and Ma. Arlyn T. Avenido (spouses Avenido) on September 20, 2000.
The spouses Avenido had obtained a loan of P2,000,000.00 from BPI Family under a Mortgage Loan Agreement dated April 25, 1996, secured by a parcel of land in Bais City covered by Transfer Certificate of Title (TCT) No. T-1216.

The spouses Avenido failed to pay their loan obligation despite demand, leading BPI Family to initiate extrajudicial foreclosure proceedings under Act No. 3135.
The property was publicly auctioned on March 8, 1999, where BPI Family was the highest bidder with a bid price of P2,142,616.00.
The total mortgage obligation as of the auction date was P2,917,381.43, creating an unpaid deficiency of P794,765.43 after applying the bid price.

BPI Family prayed for payment of the deficiency plus legal interest, attorney’s fees, litigation expenses, and costs.
The spouses Avenido filed an Answer with affirmative defenses and counterclaims, arguing that they had paid a substantial amount exceeding P1,000,000.00 and that unfair charges and penalties inflated their debt.
The spouses contended that the auction sale price exceeded their indebtedness and sought damages for the unjust suit and release of their fully paid motor vehicle encumbered by BPI Family due to the deficiency claim.

BPI Family’s witness, Alfred Rason, testified on the loan computation and auction details, highlighting that the bid price represented 80% of the appraised value per bank policy.
Arlyn Avenido corroborated failure to pay some installments and complained of lack of notification prior to foreclosure and a demand for unpaid deficiency only after auction.

The RTC recognized the right of the mortgagee to recover deficiency but found the BPI Family’s claim overstated due to inclusion of unsupported liquidated damages.
The court computed the total amount due at P2,598,452.80.
It held that since the property’s fair market value (P2,678,270.00) exceeded the outstanding loan, allowing deficiency recovery would unjustly enrich BPI Family.
The complaint and counterclaim were dismissed.

The CA affirmed the RTC ruling that the mortgagees are at disadvantage when they buy at auction and the courts must protect the mortgagor from unjust enrichment.
The CA emphasized the mortgage contract as a contract of adhesion, to be construed strictly against the bank’s claim.
The CA ruled that the deficiency claim was improper since the auction bid was considered nominal and less than market value.

BPI Family filed a Petition for Review challenging the CA’s ruling.
The issue was whether BPI Family is entitled to collect the deficiency mortgage obligation based on the auction bid price or the property’s market value.

Whether BPI Family, as mortgagee, is entitled to collect deficiency from the spouses Avenido after extrajudicial foreclosure and public auction sale.
Whether the proper basis for determining deficiency is the auction sale price or the fair market value of the foreclosed property.
Whether the principle of unjust enrichment bars BPI Family from recovering deficiency when its auction bid was only 80% of the property’s appraised value.
