In Philippine civil law, the lease of immovable property creates a temporary relationship between lessor and lessee that balances the owner’s ultimate dominion over the thing with the lessee’s right to its peaceful and useful enjoyment. A recurring issue arises when the lessee, during the lease term, introduces improvements that enhance the property’s value or utility. The Civil Code of the Philippines expressly regulates the lessee’s right to reimbursement for such improvements, particularly “useful improvements,” and addresses how the sale of the leased property affects that right. This article comprehensively examines the legal framework, conditions, mechanics, and consequences of the lessee’s right to reimbursement for useful improvements, with special emphasis on the impact of alienation or sale of the leased property.

Legal Basis

The principal provision is Article 1678 of the Civil Code, which states:

“The lessee may make useful improvements on the thing leased provided he does not alter its form or substance. However, the lessee shall not have any right to indemnity for such improvements unless the lessor has expressly consented thereto. In such case, the rules on necessary and useful expenses of a possessor in good faith under Articles 546 and 547 shall apply.”

When the lessor gives express consent, the lessee stands in the position of a possessor in good faith. Article 546 entitles such a possessor to reimbursement of all necessary and useful expenses and grants a right of retention until full payment is made. Article 547 further provides that useful improvements may be removed by the possessor (here, the lessee) without damage to the principal thing if the owner (lessor or successor) does not reimburse; conversely, the owner may elect to retain the improvements by paying their value.

Complementary provisions include:

Article 1676, which governs the effect of sale on existing leases: the purchaser of a leased property is bound by the lease if the lease contract is recorded in the Registry of Property or if the purchaser had actual knowledge of the lease. In such cases, the buyer is subrogated to the rights and obligations of the original lessor.
General rules on obligations and contracts (Articles 1156–1317) and accession (Articles 440–475), which prevent unjust enrichment.
The lessee’s obligation under Article 1665 to return the property in the condition received, save for wear and tear, which is reconciled with the separate right to indemnity for consented improvements.

These provisions reflect the policy of protecting the lessee’s good-faith investment while preserving the lessor’s dominion and preventing the lessee from transforming a lease into a disguised ownership claim.

Definition and Classification of Improvements

Philippine law classifies improvements into three categories:

Necessary improvements – Those required for the preservation or continued use of the property (e.g., major roof repairs to prevent collapse). The lessee is entitled to full reimbursement regardless of consent, as these expenditures benefit the lessor directly.
Useful improvements – Those that increase the property’s value, productivity, or suitability for its intended purpose without changing its essential form or substance (e.g., installing air-conditioning systems in a commercial space, constructing additional partitions in an office, or paving a dirt driveway). These are the focus of Article 1678.
Ornamental or luxurious improvements – Those made for aesthetic or personal pleasure (e.g., decorative fixtures or landscaping purely for beauty). The lessee may generally remove them without causing damage to the property but has no right to indemnity unless the lessor expressly consents and elects to retain them.

Useful improvements must be suitable to the purpose of the lease and must not alter the property’s form or substance. Alterations that amount to structural changes may be treated as prohibited acts under the lease contract or as bad-faith acts.

Conditions for the Right to Reimbursement

The right to reimbursement for useful improvements is not absolute. The following cumulative conditions must be satisfied:

Express consent of the lessor. Mere silence or tolerance does not constitute consent; the consent must be clear and preferably documented in writing to avoid disputes. Without express consent, the lessee has no right to indemnity and may only remove the improvements if removal causes no damage.
Good faith on the part of the lessee. The lessee must believe he has the right to make the improvement or that the lessor has consented. Improvements made maliciously or in obvious bad faith forfeit any claim.
Suitability and non-alteration. The improvement must enhance the property’s utility for the leased purpose and must not transform its character.
Existence of the lease at the time of making the improvement. The right arises only during the lease term.

When these conditions are met, the lessee acquires two principal rights: (1) reimbursement of the useful expenses (ordinarily the amount by which the property’s value increased or the reasonable cost, whichever protects against unjust enrichment), and (2) the right of retention, allowing the lessee to remain in possession until full payment.

Mechanics of Reimbursement and Valuation

Reimbursement is typically due upon termination of the lease, not automatically upon the making of the improvement. The lessor (or successor) has the option either to:

Pay the value of the useful improvements and retain them, or
Allow the lessee to remove the improvements, provided removal causes no damage to the leased property.

Valuation occurs at the time payment is demanded or the lease terminates, taking into account depreciation, wear and tear, and current market conditions. Expert appraisal is ordinarily required in contested cases. The lessee bears the burden of proving the cost, necessity/utility, consent, and increased value. Documentary evidence—such as written consent, invoices, and photographs before and after—is critical.

The right of retention serves as the lessee’s primary remedy against non-payment. Courts may enforce this through specific performance or by refusing to issue a writ of execution for eviction until reimbursement is satisfied.

Effect of Sale of the Leased Property

The sale of the leased property does not automatically extinguish the lease or the lessee’s right to reimbursement. The outcome depends on whether the buyer is bound by the existing lease:

Buyer bound by the lease (lease recorded in the Registry of Property or buyer had actual knowledge). The buyer is subrogated to the original lessor’s rights and obligations under Article 1676. The buyer therefore assumes the duty to reimburse for useful improvements previously consented to by the seller, and any new improvements made after the sale require the buyer’s consent. The lessee may exercise the right of retention against the buyer. The lease continues according to its terms, and reimbursement crystallizes at the original expiration date or upon lawful termination.
Buyer not bound (unrecorded lease and buyer in good faith without knowledge). The buyer may terminate the lease by giving due notice and evicting the lessee on the ground of superior title. In such cases, the lease is deemed terminated by the sale, and the original lessor remains liable for reimbursement of consented useful improvements. The original lessor may also be liable for damages if the sale was made in bad faith or without notice to the lessee. The buyer takes the property “as is” but is not personally liable for the lessee’s claim unless the buyer expressly assumes the obligation.

In both scenarios, the right to reimbursement does not accrue immediately upon sale unless the sale itself causes termination of the lease. If the lease continues, the obligation merely passes to the new owner. Judicial sales (e.g., foreclosure or execution sales) are treated similarly, though the purchaser at public auction may be considered in good faith and thus unbound if the lease was unrecorded.

Special Considerations and Related Laws

Lease contracts may stipulate terms regarding improvements (e.g., waiver of reimbursement or ownership of improvements by the lessor), provided such stipulations do not contravene law, morals, good customs, public order, or public policy.

In agricultural leasehold relations, Republic Act No. 3844 (Agricultural Land Reform Code), as amended, grants tenants stronger protections, including compensation for permanent improvements and even rights of pre-emption or redemption in case of sale. Residential leases under Republic Act No. 9653 (Rent Control Act of 2009, and its successors or extensions) primarily regulate rental amounts but do not alter the Civil Code rules on improvements. Commercial and industrial leases remain governed principally by the Civil Code and the specific contract.

In subleases or assignments, the sublessee’s improvements require consent of both the head lessor and sublessor, and rights flow accordingly.

Remedies and Procedural Aspects

A lessee whose right is denied may file an ordinary action for specific performance, sum of money, or damages before the appropriate court (Metropolitan Trial Court or Regional Trial Court depending on the amount and nature). Preliminary injunction or temporary restraining order may be sought to prevent eviction or sale pending resolution. Prescription follows the general ten-year period for written obligations (Article 1144) or four years for oral, running from the date the right accrues—usually lease termination or demand for payment.

Courts consistently apply the rules strictly to prevent unjust enrichment while respecting the temporary nature of lease. The lessee cannot claim ownership or force the lessor to sell the property; the remedy remains monetary reimbursement or removal.

Policy and Practical Implications

The regime under Articles 1678, 546, and 547 strikes a balance: it encourages the lessee to maintain and enhance the leased premises when the lessor consents, while protecting the lessor from unwanted or unauthorized encumbrances. Upon sale, the law ensures continuity of legitimate expectations by binding knowledgeable or recorded purchasers, thereby promoting stability in lease transactions and protecting good-faith investments. Parties are well-advised to document consent, maintain records of improvements, and consider registration of long-term leases to safeguard rights against third-party buyers.

This framework, rooted in the Civil Code and refined through decades of application, remains the cornerstone of the lessee’s right to reimbursement for useful improvements in the Philippine jurisdiction, whether the property remains with the original lessor or passes to a new owner by sale.
