Litis Pendentia: When Foreclosure Bars a Later Collection Suit

The Supreme Court’s 2015 ruling in Marilag v. Martinez clarifies an important rule for creditors and debtors alike: a mortgagee who chooses to foreclose a real estate mortgage cannot later file a separate collection suit for the same debt. The case explains how the principle of litis pendentia — literally, a pending suit — bars such a second action, and it also addresses excessive interest rates and the return of overpayments.

The Facts of the Case

In 1992, Rafael Martinez obtained a P160,000 loan from Norlinda Marilag, secured by a real estate mortgage, with a stipulated monthly interest of 5%. When Rafael defaulted, Marilag filed a judicial foreclosure case in 1995. The trial court declared Rafael in default and, in January 1998, ruled that the 5% monthly interest was usurious, reducing it to 12% per annum and ordering Rafael to pay P229,200.

Meanwhile, Rafael’s son, Marcelino Martinez, agreed to pay his father’s obligation, which was then pegged at P689,000. After paying P400,000, he executed a promissory note for the P289,000 balance. When he later learned of the foreclosure decision, he refused to pay the balance, claiming he had already overpaid. Marilag then filed a collection suit against Marcelino.

The trial court initially ordered Marilag to return the excess payment, but later reversed itself. The Court of Appeals reinstated the original ruling, and the case reached the Supreme Court.

The Issue

The central question was whether Marilag’s collection suit against Marcelino was barred by the earlier foreclosure case.

The Ruling: Litis Pendentia Applies

The Supreme Court held that the collection suit was barred by litis pendentia. While the Court found that res judicata did not apply — because the foreclosure decision had not yet become final — the principle of litis pendentia nevertheless barred the second action.

For litis pendentia to apply, three requisites must concur: (1) identity of parties, or at least parties representing the same interests; (2) identity of rights asserted and reliefs prayed for, founded on the same facts; and (3) a judgment in the pending case would amount to res judicata in the other. All three were present here.

One Debt, One Cause of Action

The Court reiterated a settled rule: in a loan secured by a real estate mortgage, the creditor has a single cause of action against the debtor — to recover the debt. The creditor may either file a personal action for collection or institute a real action to foreclose the mortgage. These remedies are alternative, not cumulative or successive. Choosing foreclosure waives the collection action, except for recovering any deficiency after the foreclosure sale.

The Court explained that the remedy is deemed chosen upon filing the complaint. Thus, Marilag’s filing of the judicial foreclosure case barred her from later filing a collection suit, regardless of whether the foreclosure decision had become final.

The Court also rejected the argument that Marcelino’s promissory note created a separate contract. The note merely represented his assumption of his father’s existing obligation; it did not novate the original loan. Since novation is never presumed, the note did not create a new, independent cause of action.

Excessive Interest and Return of Overpayment

The Court found the stipulated 5% monthly interest excessive and unconscionable, noting that rates of 3% per month and higher have consistently been struck down. It reduced the interest to 1% per month (12% per annum). Computing the amounts due, the Court found that Marcelino had overpaid by P134,400, which Marilag was ordered to return with 6% legal interest from the filing of the answer. The Court deleted the award of attorney’s fees because the trial court failed to state its factual and legal basis in the body of its decision.

Practical Takeaways

• A mortgagee must choose between foreclosure and a collection suit; filing one bars the other, even if the first case is still pending.
• Litis pendentia can bar a second suit even when res judicata does not yet apply because the first judgment is not final.
• A third person’s assumption of a debtor’s obligation does not create a new contract or novate the original loan unless clearly and unequivocally shown.
• Stipulated interest rates of 3% per month or higher are generally excessive, unconscionable, and void; courts may reduce them to reasonable rates.
• Courts must state the factual and legal basis for awarding attorney’s fees in the body of the decision, not merely in the dispositive portion.
