Quick answer

A landlord may stop unauthorized subleasing or a prohibited use of rental property, terminate the lease when the contract or law permits, demand restoration of the premises, recover proven losses, and—if the tenant refuses to leave—file an ejectment case.

But the landlord should first determine whether there is an actual breach:

Subleasing is generally allowed unless the lease expressly prohibits or restricts it. Article 1650 of the Civil Code recognizes subleasing when it has not been expressly prohibited.
Assignment is different from subleasing. Under Article 1649, a tenant generally cannot assign the lease to another person without the landlord’s consent unless the contract provides otherwise.
A tenant must use the property only for the purpose stated in the lease or, if no purpose was stated, according to the property’s nature and local custom. A prohibited, damaging, illegal, or materially different use may justify termination and damages.

Even when the violation is clear, a landlord should not forcibly evict the occupants, change the locks, remove belongings, shut off utilities, or use threats. If the tenant will not surrender the property voluntarily, possession should be recovered through the proper legal process.

First determine what the tenant actually did

The legal remedy depends on whether the arrangement is a sublease, an assignment, a guest arrangement, or merely the tenant’s use of workers or contractors.

Sublease

A sublease ordinarily exists when the original tenant:

Retains the original lease;
Gives another person the right to occupy all or part of the property; and
Usually receives rent or another benefit from that person.

The original tenant remains bound to the landlord. Article 1650 also makes the sublessee responsible to the landlord for acts concerning the use and preservation of the property in the manner agreed between landlord and tenant.

Because the Civil Code permits subleasing unless it is expressly prohibited, silence in the lease does not automatically make every sublease unlawful. The exact contract language remains critical. A clause may:

Completely prohibit subleasing;
Require prior written consent;
Permit only specified occupants;
Limit subleasing to part of the premises; or
Treat unauthorized subleasing as a ground for termination.

If the contract merely says that the property is “for residential use,” that language may prohibit commercial or transient-accommodation use without necessarily prohibiting every shared-occupancy arrangement.

Assignment of the lease

An assignment occurs when the tenant transfers the leasehold interest to another person who effectively takes the tenant’s place. Article 1649 of the Civil Code generally requires the landlord’s consent for an assignment unless the lease provides otherwise.

Labels are not controlling. Calling a document a “sublease,” “management agreement,” or “authorization” will not prevent a court from examining whether the original tenant actually surrendered possession and transferred the lease.

Guests, family members, employees, or caretakers

The presence of another person does not automatically establish a sublease. Relevant questions include:

Does the original tenant still live in or control the property?
Is the occupant paying rent?
Does the occupant have exclusive possession of a room, unit, or commercial space?
How long has the person stayed?
Did the tenant advertise the premises to the public?
Does the contract identify permitted occupants?
Has the occupant represented that they—not the tenant—operate or possess the property?

The landlord needs evidence of the actual arrangement, not merely suspicion or the presence of an unfamiliar person.

When use of the property violates the lease

Article 1657 of the Civil Code requires the tenant to use the leased property with due care and according to the stipulated purpose. If the parties did not specify a purpose, the tenant must use it according to the nature of the property and local custom.

Possible violations include:

Operating a business in premises leased solely as a residence;
Converting a long-term residential unit into transient or short-term accommodation contrary to the lease;
Using a warehouse for manufacturing when only storage was authorized;
Conducting activities that violate zoning, fire-safety, condominium, subdivision, or licensing rules;
Making unauthorized structural alterations;
Storing hazardous materials contrary to the contract or applicable regulations;
Creating excessive noise, congestion, sanitation problems, or other serious disturbances;
Allowing activities that damage or materially increase the risk to the property; or
Using the property for unlawful conduct.

Not every minor or technical deviation automatically warrants eviction. The contract language, seriousness of the breach, possibility of correction, actual harm, prior tolerance, and applicable notice-and-cure provisions must all be considered.

Remedies available to the landlord

1. Demand that the tenant stop or correct the violation

The landlord may issue a written notice requiring the tenant to:

Stop the prohibited activity;
Remove an unauthorized subtenant or occupant;
Obtain consent if the landlord is willing to regularize the arrangement;
Restore altered portions of the property;
Obtain required permits or comply with building rules; or
Explain the arrangement and provide relevant documents.

The notice should identify the specific lease provision and facts involved. Vague accusations such as “illegal occupancy” may create unnecessary disputes about what the tenant was expected to correct.

If the lease provides a cure period, notice method, or escalation procedure, the landlord should follow it. A notice sent by the wrong method or before the contractual cure period expires may weaken a later termination.

2. Terminate or rescind the lease

A substantial breach of a reciprocal obligation may support rescission under Article 1191 of the Civil Code. In lease disputes, Articles 1657 and 1673 are also important. Article 1673 permits judicial ejectment for grounds that include:

Expiration of the lease period;
Nonpayment of rent or agreed charges;
Violation of lease conditions; and
Devoting the property to a use not stipulated that causes deterioration, or using it in a manner inconsistent with the nature of the property.

Rescission is not ordinarily justified by a slight, casual, or trivial breach. Whether a violation is sufficiently substantial depends on the contract and circumstances. A lease may also contain a valid termination clause specifically addressing unauthorized subleasing, assignment, occupancy, or prohibited use.

The landlord should communicate termination unequivocally and state:

The breach relied upon;
The contractual or legal basis;
Whether an opportunity to cure was provided or was unnecessary under the contract;
The effective termination date;
The deadline to vacate and surrender the keys; and
The amounts claimed, if any.

3. Recover possession through unlawful detainer

If the tenant’s possession was initially lawful but became unlawful after expiration or valid termination of the lease, the usual summary remedy is unlawful detainer under Rule 70 of the Rules of Court.

Except where the applicable rules or controlling jurisprudence recognize that no prior demand is necessary—such as particular cases based purely on expiration—a clear written demand remains the prudent course. Where the suit is based on failure to pay rent or comply with lease conditions, Rule 70 specifically contemplates a demand to pay or comply and to vacate.

An unlawful-detainer action must generally be filed within one year from the relevant last demand or from the point possession became unlawfully withheld, depending on the legal and factual basis of the case. Pleading the dates correctly is essential. If the case falls outside Rule 70’s one-year period, the appropriate action may instead be an ordinary action to recover the better right of possession, subject to the proper court’s jurisdiction.

Ejectment cases are filed in the first-level court—such as the Metropolitan Trial Court, Municipal Trial Court, Municipal Trial Court in Cities, or Municipal Circuit Trial Court—where the property is located. They are governed by Rule 70 and the Supreme Court’s Rules on Expedited Procedures in the First Level Courts.

A favorable judgment, not private force, authorizes recovery of possession through court enforcement.

4. Claim unpaid rent, reasonable compensation, and damages

Depending on the evidence and contract, the landlord may seek:

Unpaid rent and agreed charges;
Reasonable compensation for continued occupancy after termination;
Repair or restoration costs;
Damage to the premises beyond ordinary wear and tear;
Contractual penalties, if valid and not unconscionable;
Attorney’s fees when authorized by the contract or law and properly justified; and
Other direct, proven losses caused by the breach.

Damages must be established with evidence. A court will not automatically award an estimated loss simply because a breach occurred. Keep invoices, inspection reports, photographs, repair quotations, receipts, correspondence, and proof connecting the loss to the tenant’s conduct.

5. Seek an injunction when continued use creates urgent harm

If the prohibited activity threatens continuing and serious injury—for example, dangerous structural work or storage of hazardous materials—the landlord may consult counsel about injunctive relief.

A temporary restraining order or preliminary injunction is not automatic. The applicant must satisfy the procedural and evidentiary requirements, including showing a clear legal right and urgent or irreparable injury. Ordinary financial loss alone may not be enough if damages would adequately address the harm.

6. Report regulatory or criminal violations to the proper authority

A contractual breach and a regulatory or criminal violation are separate matters. Depending on the activity, the appropriate authority may include:

The city or municipal zoning or business-permits office;
The Bureau of Fire Protection;
The condominium corporation or homeowners’ association;
Building officials;
Environmental, health, or sector-specific regulators; or
Law-enforcement authorities for apparent criminal activity.

Reports should be factual and supported by available evidence. A landlord should not publicly accuse the tenant of a crime without a sound factual basis.

For immediate danger—such as fire, violence, explosives, toxic exposure, or an active crime—contact emergency responders or law enforcement without waiting for the lease dispute to be resolved.

Barangay conciliation may be required first

Before filing in court, the parties may need to undergo barangay conciliation under Sections 408 and 412 of the Local Government Code when the dispute and parties fall within the Katarungang Pambarangay system.

Coverage depends on factors such as the parties’ actual residences and the statutory exceptions. Urgent court relief, disputes involving certain public officers or government entities, and cases involving juridical persons may be treated differently. The landlord should verify whether a Certificate to File Action is required before commencing suit.

Barangay proceedings do not authorize the landlord to seize the premises. A settlement reached there should clearly state the vacating date, payment terms, turnover condition, treatment of the deposit, and consequences of default.

The landlord should not use self-help eviction

Even if the tenant plainly violated the lease, the landlord should not:

Change locks while the tenant or occupants remain in possession;
Shut off electricity, water, internet, or other essential services to force departure;
Enter the premises without contractual or lawful authority;
Remove, retain, sell, or dispose of the occupants’ belongings;
Threaten, intimidate, or physically remove occupants;
Destroy fixtures installed by the tenant;
Harass customers, employees, guests, or family members; or
Falsely represent that a court has already ordered eviction.

Articles 536 and 539 of the Civil Code protect possession against forcible interference and direct a claimant to seek assistance from the competent courts when the possessor objects. Improper self-help may expose the landlord to injunctions, damages, or possible criminal complaints.

An emergency entry expressly allowed by the lease may be defensible when reasonably necessary to address an actual emergency, but it should not be used as a pretext to dispossess the tenant.

What the tenant or subtenant can do

A tenant who receives a notice should review the entire lease and respond promptly. Possible defenses or responses include:

The lease does not prohibit subleasing;
The occupant is a guest, employee, family member, caretaker, or authorized occupant rather than a subtenant;
The use remains within the permitted purpose;
The landlord previously gave written or provable consent;
The landlord knowingly accepted the arrangement for a substantial period;
The alleged breach was cured within the allowed period;
Termination did not follow the contract’s notice requirements;
The demand identifies the wrong property, violation, amount, or deadline; or
The person demanding possession lacks authority from the owner or lessor.

Waiver, estoppel, or consent should not be assumed merely because the landlord did not object immediately. Their application is fact-dependent, especially where the lease requires written consent or contains a non-waiver clause.

A subtenant should understand that a sublease ordinarily cannot give better rights against the landlord than those lawfully held by the original tenant. Termination of the principal lease may affect the subtenant’s right to remain, although contractual claims against the original tenant may survive.

Evidence to preserve

For the landlord

Preserve:

The signed lease and all renewals, addenda, house rules, and turnover documents;
The property title or proof of authority to lease and sue;
Written consent requests and responses;
Notices of violation, cure notices, termination notices, and demands to vacate;
Proof of personal service, courier delivery, registered mail, email, or other agreed service;
Advertisements for the property, including screenshots showing the URL and date;
Messages between the tenant, occupants, brokers, customers, or property manager;
Lawfully obtained photographs, videos, inspection reports, and access logs;
Records of payments received from the tenant;
Regulatory notices or inspection findings;
Complaints from neighbors, administrators, or associations; and
Repair invoices and evidence of the property’s condition before and after the lease.

For the tenant or subtenant

Preserve:

The complete lease and any agreement with the original tenant;
Written or electronic proof of the landlord’s consent;
Receipts and payment records;
Messages showing the landlord’s knowledge of the occupants or activity;
Permits and proof that the use complies with the lease;
Inspection records and photographs of the property’s condition;
The notice, envelope, delivery record, and date it was received; and
Evidence that the alleged violation was corrected.

Keep original electronic files where possible. Avoid editing screenshots in a way that removes dates, account details, URLs, or surrounding context.

A practical step-by-step approach for landlords

Read the complete lease. Identify the provisions on subleasing, assignment, occupants, permitted use, inspections, default, cure periods, termination, notice, and dispute resolution.
Verify the facts lawfully. Do not rely solely on rumors or trespass into the premises. Determine who occupies the property, what activity occurs, and whether money or possession changed hands.
Classify the violation correctly. Decide whether it involves a sublease, assignment, additional occupant, prohibited use, nuisance, property damage, or regulatory violation.
Document the breach. Preserve advertisements, correspondence, inspection results, official records, and witness information.
Send a precise written notice. State the facts, lease provisions, required corrective action, deadline, and possible termination.
Evaluate the response. The tenant may provide consent, permits, proof that no sublease exists, or evidence that the breach has been cured.
Serve termination and demand properly. If termination is justified, clearly demand surrender of the premises and comply with contractual notice requirements.
Complete barangay proceedings if required. Obtain the proper certification before filing when the Local Government Code applies.
File the correct action on time. Ensure that the complaint alleges the lease, violation or expiration, termination, demand when required, failure to vacate, and dates establishing the court’s jurisdiction.
Use court enforcement. Do not personally carry out the eviction.

Common mistakes

Assuming every sublease requires consent despite the Civil Code’s default rule;
Confusing a sublease with an assignment;
Using a residential-use clause as if it were automatically a no-subletting clause;
Relying on an oral warning when the lease requires written notice;
Failing to demand both compliance and surrender when Rule 70 requires it;
Letting the one-year ejectment period pass without legal advice;
Accepting rent after termination without documenting what the payment represents;
Treating the security deposit as an automatic penalty or forfeiture;
Claiming speculative damages without receipts or other proof;
Filing before completing mandatory barangay conciliation;
Naming only the tenant even though other occupants openly claim independent possession;
Entering the premises or collecting evidence unlawfully; and
Attempting a lockout or utility disconnection instead of obtaining a court order.

Acceptance of money after a notice of termination can create factual disputes about waiver, renewal, or continued occupancy. If payment is accepted, the receipt and correspondence should accurately state whether it is rent, arrears, or reasonable compensation for use and occupancy, subject to applicable law.

When legal help is urgent

Consult a Philippine lawyer promptly when:

A demand to vacate has already been served or received;
The one-year period for unlawful detainer may be close to expiring;
The lease contains automatic-termination, forfeiture, arbitration, or unusual notice clauses;
The landlord has accepted rent after learning of the violation;
The premises are being used for short-term rentals, hazardous operations, or apparent unlawful activity;
A condominium corporation, homeowners’ association, regulator, or local government has issued a violation notice;
Structural alterations or significant damage are continuing;
Several occupants or businesses claim separate rights to possess the property;
The original lease has expired but occupation continued with the landlord’s acquiescence;
The landlord is considering an injunction; or
Either side is considering changing locks, disconnecting utilities, or removing belongings.

Frequently asked questions

Can a landlord evict a tenant merely for subleasing?

Not always. Under Article 1650 of the Civil Code, subleasing is generally possible when it has not been expressly prohibited. Eviction is more supportable when the lease clearly prohibits subleasing, requires consent that was not obtained, or the arrangement separately violates the permitted-use or occupancy provisions.

Is the landlord’s consent always required?

For an assignment, consent is generally required under Article 1649 unless the lease says otherwise. For a sublease, the Civil Code’s default rule is different: it may be made unless expressly prohibited. The contract may nevertheless require prior written consent.

Can the landlord remove the subtenant directly?

The landlord should not forcibly remove any occupant. The demand and court pleadings should address all persons whose possession must be terminated, based on counsel’s assessment of their claimed rights and the procedural rules.

Can the landlord keep the entire security deposit?

Not automatically. Application or forfeiture of the deposit depends on the contract, the nature of the breach, unpaid obligations, proven damage, and applicable law. The landlord should provide a defensible accounting and avoid treating the deposit as a substitute for proof of loss.

What if the prohibited activity stops after notice?

Cure may prevent termination if the contract gives the tenant a right to cure and the breach is fully corrected on time. It does not necessarily erase accrued damages or prior violations. Repeated or incurable breaches require separate evaluation.

What if the lease has no stated duration?

Article 1687 of the Civil Code supplies rules for leases without a fixed period, depending in part on how rent is paid. The parties’ conduct and any implied renewal under Article 1670 may also matter. Legal advice is advisable before issuing a termination notice.

May the landlord inspect the property?

Only according to the lease and law, normally with reasonable notice unless there is a genuine emergency. Ownership does not give an unrestricted right to enter premises currently possessed by a tenant.

Is a demand letter enough to evict the tenant?

No. A demand may terminate the right to remain and establish a basis for suit, but it does not itself authorize physical eviction. If the occupants refuse to surrender possession, the landlord generally needs a court judgment and lawful execution.
