Amending Lease Contracts: Upholding Written Agreements and Preventing Unjust Enrichment

The Supreme Court, in Spouses Manzanilla v. Waterfields Industries Corporation (G.R. No. 177484, July 18, 2014), clarified important rules on amending lease contracts, the binding effect of judicial admissions, and the limits of the unjust enrichment principle. The ruling is a reminder that a lessee who violates a lease agreement cannot escape ejectment by claiming it spent heavily on improvements, nor can it contradict its own admissions in court.

The Facts of the Case

The spouses Manzanilla owned a parcel of land in Batangas. In May 1994, they leased a 6,000-square meter portion to Waterfields Industries Corporation for 25 years at a monthly rental of P18,000. Waterfields paid a rental deposit of P216,000, which the contract stated would answer for unpaid rentals, damages, penalties, and unpaid utility charges.

The parties executed an amendment in June 1994, but by April 1997, Waterfields began failing to pay rent. In a letter dated July 9, 1997, Waterfields' president promised to pay arrears and stated that the deposit would thereafter be used exclusively for unpaid utilities and incidental expenses, applied only at termination of the lease.

Despite this, Waterfields still failed to pay rentals from December 1997 to May 1998. The spouses Manzanilla filed an unlawful detainer case, and the lower courts ruled in their favor. The Court of Appeals reversed, applying the principle of compensation and holding that the deposit covered the unpaid rentals. The Supreme Court reversed the CA and reinstated the ejectment.

The Issue: Did the Lessee Violate the Lease?

The central question was whether Waterfields failed to pay rent, which would constitute a violation of the lease and give rise to a cause of action for unlawful detainer.

The Court held that for unlawful detainer, two requisites must concur: (1) failure to pay rent or comply with the lease conditions, and (2) demand to pay or vacate. Here, demand was not in question. The issue was whether Waterfields violated the lease by non-payment.

Judicial Admissions Are Binding

Waterfields argued that the July 9, 1997 letter was unenforceable under the Statute of Frauds because it was not notarized or signed by both parties. The Court rejected this argument.

In its Answer, Waterfields expressly admitted paragraph 5 of the Complaint, which alleged that the Contract of Lease was amended on July 9, 1997. Under Section 4, Rule 129 of the Rules of Court, judicial admissions do not require proof and can only be contradicted by showing palpable mistake. The doctrine of estoppel also barred Waterfields from denying its own admission to the prejudice of the other party.

The Court also noted that even without the admission, the contemporaneous and subsequent acts of the parties showed their intention to amend the contract, per Article 1371 of the Civil Code.

Unjust Enrichment Does Not Apply

Waterfields claimed that ejecting it would result in unjust enrichment because it spent nearly P10 million developing the property. The Court disagreed.

Unjust enrichment requires two conditions: (1) a person is benefited without valid basis or justification, and (2) the benefit is derived at the expense of another. Neither condition was met here. The spouses Manzanilla were justified in recovering possession because Waterfields violated the lease by failing to pay rent. By violating the contract, Waterfields took the risk of losing its improvements in favor of the lessors.

Practical Takeaways

• Amendments to lease contracts are binding. A written amendment, even if not notarized, can be effective if the parties' acts show their intention to be bound by it.
• Judicial admissions are powerful. A party cannot contradict admissions made in its pleadings without showing palpable mistake.
• Unjust enrichment is a narrow doctrine. It does not protect a lessee who violated the contract, even if it spent heavily on improvements.
• Failure to pay rent creates a cause of action. In unlawful detainer, the cause of action arises from the violation itself, not from the termination of the contract.
• Deposit terms matter. A lease deposit can only be used for the purposes stated in the contract or its valid amendments.
