Summary
This case involves a dispute between related parties over loan obligations and the scope of real estate mortgage security. Petitioners obtained an initial P1,500,000 loan secured by real estate mortgage plus additional loans totaling P1,250,000. Upon default, respondents filed foreclosure claiming all loans were secured by the mortgage. The Supreme Court affirmed that legal interest of 12% per annum on stipulated interest is mandated by law from the time of judicial demand under Article 2212 of the Civil Code. However, the Court ruled that only the original loan was properly secured by the mortgage, as additional loan arrangements were made through private documents insufficient to legally bind the mortgaged property. The decision established clear guidelines for interest computation in mortgage foreclosure cases and emphasized the formal legal requirements for mortgage amendments.
