SUBJECT: The Concept of ‘Equitable Mortgage’

I. Introduction and Purpose of Memo
This memorandum provides an analysis of the concept of an equitable mortgage under Philippine law. Its purpose is to elucidate this judicial doctrine, which treats certain transactions, despite their documentary form as absolute sales or other contracts, as mortgages intended to secure an obligation. Understanding this concept is crucial for practitioners in credit transactions to protect the rights of borrowers, ensure compliance with usury and lending laws, and properly characterize transactions for foreclosure and redemption purposes.
II. Legal Foundation and Definition
An equitable mortgage is established not by explicit agreement, but by operation of law under Article 1602 in relation to Article 1604 of the Civil Code. When a transaction, documented as an absolute sale or other conveyance, is proven to have been intended by the parties as security for a loan, the courts will treat it as a mortgage. The law looks beyond the nomenclature of the contract to ascertain the true intent and agreement of the parties. This doctrine is rooted in the principle that a mortgage is merely an accessory contract securing a principal obligation, and the law will not permit the form of a transaction to subvert its substance, especially to the detriment of the economically disadvantaged borrower.
III. Key Statutory Presumptions (Article 1602, Civil Code)
Article 1602 enumerates specific circumstances where a contract purporting to be an absolute sale shall be presumed to be an equitable mortgage. This presumption is juris tantum and may be rebutted by clear and convincing evidence. The circumstances are:

The price of the sale is unusually inadequate.

The vendor remains in possession of the property.

The vendor retains a right to repurchase the property.

The purchaser retains a part of the purchase price, which is treated as a loan.

The vendor binds himself to pay taxes on the property not sold.

In any other case where it may be fairly inferred that the real intention was to secure a loan.

IV. Essential Elements for Declaration
For a court to declare the existence of an equitable mortgage, the following elements must concur: (1) The parties entered into a contract denominated as a sale (or similar conveyance); and (2) Their true intention was to secure an existing or future debt by way of a mortgage. The second element is paramount. Proof can be extrinsic, including parol evidence, as the rule on integration of writings does not apply when the very nature of the contract is in issue. The inadequacy of the price, continuous possession by the “seller,” and the subsequent acts of the parties (e.g., payment of real estate taxes, insurance, or acknowledgment of indebtedness) are critical indicators.
V. Distinction from Pactum Commissorium
It is vital to distinguish an equitable mortgage from a pactum commissorium, which is absolutely prohibited under Article 2088 of the Civil Code. A pactum commissorium is a stipulation authorizing the creditor to appropriate the property upon the debtor’s default without the need for foreclosure. In an equitable mortgage, the transaction is re-characterized as a mortgage; consequently, the creditor must still observe the formal foreclosure procedures prescribed by law (either judicial or extrajudicial under Act No. 3135 , as amended). Declaring a transaction as an equitable mortgage saves it from nullity as a pactum commissorium.
VI. Impact on Interest Rates and Usury Laws
When a transaction is declared an equitable mortgage, the “purchase price” is considered the principal loan. Any excess in the actual value of the property over this amount, or any subsequent payments demanded for “redemption,” may be treated as interest. Courts will scrutinize these to ensure effective interest rates do not contravene the principles against unconscionable interest under the Civil Code and relevant circulars of the Bangko Sentral ng Pilipinas, even in the absence of a specific usury ceiling.
VII. Burden of Proof and Evidence
The burden of proving that a contract is an equitable mortgage rests upon the party asserting it, usually the borrower-vendor. However, once any of the circumstances in Article 1602 is shown to exist, the presumption arises, shifting the burden of evidence to the other party to overcome it. Evidence can include: the contemporaneous existence of a loan; documents acknowledging indebtedness; receipts for interest payments; the gross inadequacy of the price; and the continuous possession and cultivation of the property by the alleged vendor.
VIII. Consequences of Declaration
Once a contract is judicially declared an equitable mortgage, the following legal consequences ensue:

The “seller” is recognized as the true owner and mortgagor.

The “buyer” is recognized only as a mortgagee-creditor.

The principal obligation is the loan, equivalent to the purported purchase price.

The right to foreclose the mortgage accrues to the creditor upon default, but he must follow the statutory foreclosure process.

The mortgagor retains the right of redemption within the period provided by law (e.g., one year from registration of the extrajudicial foreclosure sale).

IX. Practical Remedies
For the Borrower/Mortgagor: If you have executed a deed of absolute sale as security for a loan, and the creditor threatens to take ownership without foreclosure, file an action for Declaration of Equitable Mortgage and Reformation of Instrument (with application for a preliminary injunction or TRO to prevent consolidation of title). Meticulously gather all evidence of the loan (text messages, receipts, witness testimonies, proof of continued possession and tax payments). Compute the effective interest rate to argue unconscionability if applicable.
For the Lender/Mortgagee: To avoid disputes, always document loan transactions with a clear and notarized Real Estate Mortgage deed. If accepting a sale as security, be aware of the risks of re-characterization. Ensure the transaction price is fair and consider structuring it as a leaseback or other legitimate arrangement if a true sale is intended. If foreclosing on a disputed transaction, initiate foreclosure proceedings under Act 3135; do not unilaterally assume ownership, as this may strengthen the borrower’s claim of a pactum commissorium. In any litigation, be prepared to present evidence rebutting the Article 1602 presumptions, such as proof of the seller’s true intent to divest ownership permanently.
