In Linda Uy Lim v. Helen O. Tong, the Supreme Court clarified the extent to which a real estate mortgage is valid. The Court ruled that a mortgage is valid only to the extent that it secures an actual loan received by the mortgagor. Any portion of the mortgage intended to secure unsubstantiated debts, particularly those of another party, is considered null and void. This decision protects property owners from having their assets encumbered for debts that are not clearly proven or directly attributable to them.

Whose Debt Is It Anyway? Challenging Mortgage Claims on Marital Property

This case revolves around Linda Uy Lim’s challenge to a real estate mortgage on her property. The mortgage was executed by her attorneys-in-fact, Helen O. Tong and Philip Ong, in favor of Propmech Corporation, to secure a purported obligation of P1,000,000. Lim argued that she only authorized the mortgage for a specific loan, and that the mortgage was fraudulently expanded to cover her estranged husband’s debts. The central legal question is whether a mortgage can validly secure debts beyond the initially agreed loan amount, especially when it includes the personal liabilities of a third party without sufficient proof or consent.

The controversy began with a Special Power of Attorney (SPA) granted by Linda Uy Lim and her husband, Saturnino Lim, to Helen O. Tong and Philip Ong. This SPA authorized Tong and Ong to mortgage their property to secure a loan. Subsequently, a Real Estate Mortgage was executed to secure a P1,000,000 obligation, which Linda Uy Lim claimed was partly for a loan she and her husband received (P400,000) and partly for her husband’s alleged misappropriation of corporate funds (P600,000). Upon receiving a Notification of Foreclosure, Linda Uy Lim filed a complaint seeking the annulment of the mortgage.

The Regional Trial Court (RTC) initially dismissed Lim’s complaint, declaring the Real Estate Mortgage legally executed. The Court of Appeals affirmed this decision. However, the Supreme Court took a different view, scrutinizing the evidence supporting the additional debt of P600,000. The Court found that there was insufficient proof to substantiate Saturnino Lim’s alleged debt to Propmech Corporation. No documentary evidence clearly demonstrated the exact amount Saturnino supposedly defalcated or that he was informed about it. This lack of evidence became a critical point in the Court’s analysis.

The Supreme Court emphasized that fraud is never presumed and must be proven by clear and convincing evidence. In this case, the Court found that while Linda Uy Lim authorized the mortgage through the SPA, the authorization was specifically for securing a loan. The Court acknowledged that Linda Uy Lim and her husband indeed obtained a loan of P400,000 from the corporation, which was proven via testimonial and documentary evidence, including checks and deposit slips made out to Linda Lim. The SPA authorized the attorneys-in-fact to mortgage the property for the purpose of obtaining or securing a loan or monetary obligation. However, it did not extend to covering unsubstantiated debts of a third party.

Building on this principle, the Court invoked the **best evidence rule**, emphasizing that when the contents of a document are in question, only the original document is admissible as evidence, unless certain exceptions apply. In this case, photocopies of letters purportedly written by Saturnino Lim admitting to “wrongdoings” and recalling having taken company funds were deemed insufficient due to the absence of the original documents. The Court also highlighted that at the time the SPA was executed in 1994, the alleged defalcated amount of Saturnino to speak of did not exist yet. Petitioner and her husband could not, therefore, have considered securing an inexistent or future unspecified liability. Consequently, the inclusion of the P600,000 in the mortgage was deemed invalid due to the lack of clear, convincing, and admissible evidence.

In its final ruling, the Supreme Court affirmed the validity of the mortgage only to the extent of the P400,000 loan. The Court declared the Deed of Real Estate Mortgage null and void insofar as it secured the additional P600,000 allegedly representing the personal obligation of Saturnino Lim to Propmech Corporation. This decision underscores the principle that a mortgage’s validity is directly tied to the actual, proven debt of the mortgagor. By invalidating the portion of the mortgage related to the unsubstantiated debt, the Court protected Linda Uy Lim’s property rights and prevented it from being used to secure debts that were not clearly established or agreed upon.
