Spouses Joven Sy v. China Banking Corporation

Summary

This case involves the collection of deficiency balance after foreclosure of mortgaged property securing loan obligations under promissory notes. Spouses Joven Sy and Corazon Que Sy defaulted on three promissory notes totaling P19,900,000.00 with China Banking Corporation. After foreclosure yielding P14,500,000.00, China Bank sought to collect the deficiency. The Supreme Court corrected computational errors by the lower courts, particularly in applying the reduced penalty charges and proper interest computation methods. The Court reduced the unconscionable penalty charges from 1/10 of 1% per day to 1% per month, corrected interest calculations to use 365 days instead of 360 days per Civil Code Article 13, and limited attorney's fees to P100,000.00. The deficiency balance was significantly reduced from P13,938,791.69 to P7,734,132.93. The case demonstrates judicial authority to equitably reduce unconscionable contractual penalties and the importance of accurate mathematical computations in determining final liability in loan deficiency cases.
