Quick answer

A landlord may seek to terminate the lease and recover possession when a tenant subleases contrary to an express prohibition, assigns the lease without the required consent, or uses the property in violation of the lease. The usual remedy is a written demand requiring compliance and surrender of the premises, followed—if the violation is not resolved—by an unlawful-detainer case in the proper first-level court.

However, an alleged “unauthorized sublease” is not automatically a breach. Under Article 1650 of the Civil Code, a tenant may generally sublet all or part of the property when the lease contains no express prohibition. Assignment is different: Article 1649 generally requires the landlord’s consent. The lease, written communications, actual arrangement, and landlord’s prior conduct must therefore be examined before action is taken.

A landlord should not forcibly evict occupants, change locks, remove belongings, or use threats to regain possession. Eviction must ordinarily proceed through lawful process.

First determine what arrangement actually exists

Labels are not decisive. Establish whether the third person is:

A guest, employee, caregiver, or family member staying with the tenant;
A roommate sharing expenses without receiving an independent right to occupy;
A sublessee paying the tenant for a defined space or independent occupancy;
An assignee who has effectively taken over the tenant’s entire leasehold position;
A business operator using residential premises commercially; or
An occupant whose presence the landlord previously approved or knowingly accepted.

A sublease creates a lease between the original tenant and a subtenant while the original tenant remains responsible to the landlord. An assignment transfers the tenant’s leasehold rights to another person. Assignment generally requires the landlord’s consent unless the contract provides otherwise. Subletting, by contrast, is generally permitted if the lease contains no express prohibition.

The original tenant remains responsible for performing the lease even when a lawful sublease exists. Under Articles 1651 and 1652 of the Civil Code, the sublessee also has obligations concerning the agreed use and preservation of the property and may, within statutory limits, be subsidiarily liable to the landlord for rent due from the tenant.

When subleasing can support termination and eviction

A landlord normally has a strong contractual ground when the lease clearly states that the tenant must not:

Sublet all or any part of the premises;
Take paying boarders or transient occupants;
List the unit for short-term accommodation;
Transfer possession or assign the lease;
Permit occupancy by persons not identified in the contract; or
Do any of these things without the landlord’s prior written consent.

Article 1673 of the Civil Code allows the judicial ejectment of a tenant for violation of a condition agreed upon in the lease. The landlord must still prove both the relevant condition and its violation.

If the lease is silent about subleasing, Article 1650 generally permits it. A landlord cannot safely assume that consent was legally required merely because consent was never requested. Other grounds may nevertheless exist—for example, an unauthorized assignment, overcrowding, structural damage, nonpayment, nuisance, illegal activity, or a use that violates an express lease restriction.

Ambiguous clauses should be assessed in context. A clause limiting the premises to “residential use,” for example, does not necessarily prohibit every guest or work-from-home activity. The scale and nature of the activity, customer traffic, alterations, nuisance, regulatory requirements, and wording of the contract may all matter.

Prohibited or materially different use

Article 1657 requires the tenant to use the property diligently and devote it to the use stipulated in the lease. When the contract does not specify a use, the use may be inferred from the property’s nature and local custom.

Potential violations include:

Converting a residential unit into a shop, warehouse, dormitory, lodging business, or production site;
Operating a business expressly prohibited by the lease;
Using the premises for unlawful activity;
Storing hazardous materials contrary to the lease or applicable safety rules;
Making unauthorized structural alterations;
Creating serious noise, sanitation, fire-safety, or security problems; or
Using the premises in a way that causes deterioration beyond ordinary wear.

Article 1673 separately recognizes as a ground for judicial ejectment a use or service not stipulated that causes deterioration, or a failure to observe the tenant’s duty under Article 1657. A minor, temporary, or curable departure will not necessarily justify the same response as a continuing, material violation. The exact lease language, seriousness of the conduct, damage, warnings, and opportunity to correct the problem are important.

Possible zoning, licensing, building, fire-safety, condominium, or homeowners’ association violations should be verified with the agency or governing body that actually has authority. A landlord should not allege that conduct is “illegal” without a reliable factual and legal basis.

Review the lease before sending a demand

Check the complete agreement and all attachments for:

The permitted use;
Subletting, assignment, guest, and occupancy restrictions;
Whether consent must be written;
Notice and cure periods;
Grounds for termination;
Renewal or holdover provisions;
Rules incorporated from a condominium or subdivision;
Notice addresses and authorized delivery methods;
Penalty, indemnity, and attorney’s-fee clauses; and
Any dispute-resolution requirement.

Also review amendments, text messages, emails, receipts, and prior dealings. A landlord who expressly approved the arrangement—or repeatedly accepted it with full knowledge—may face arguments involving consent, waiver, or modification. Acceptance of rent does not invariably waive a breach, but the surrounding facts can affect the case.

For an oral lease, gather evidence showing the agreed rent, duration, purpose, occupants, and restrictions. Proving an unwritten restriction against subletting is considerably harder because the Civil Code’s default rule allows subletting when no express prohibition exists.

Evidence to preserve

Preserve evidence lawfully and in its original form. Useful records may include:

The signed lease, amendments, inventory, and house rules;
The title, tax declaration, authority to lease, or other proof of the landlord’s right to possess;
Advertisements offering the property or rooms for rent;
Booking pages and dated screenshots showing the URL and account;
Messages discussing rent, guests, business use, or consent;
Payment records involving the tenant and alleged subtenant;
Security logs, access records, and authorized incident reports;
Photographs or videos taken from lawful locations;
Inspection notices and reports;
Complaints from neighbors supported by firsthand statements;
Building, fire, zoning, licensing, or association notices;
Repair estimates and proof of actual damage;
The written demand and proof of delivery, refusal, or posting; and
A dated chronology identifying who personally observed each event.

Do not trespass, secretly obtain private communications, impersonate a customer, or conduct an inspection contrary to the lease or law. Avoid collecting more personal information than is reasonably needed.

Statements such as “the guard said the unit is being rented out” are weaker than testimony from a person with direct knowledge, authenticated records, or admissions by the tenant.

Send a precise written demand

For unlawful detainer based on breach, the prudent demand should:

Identify the property and lease.
Quote or accurately describe the violated provision.
State the verified facts constituting the violation.
Demand compliance within the applicable contractual or legal period.
Demand that the tenant vacate and surrender possession if the breach is not timely cured or if the lease is validly terminated.
Address unpaid rent or other amounts separately and provide a clear computation.
Reserve claims without exaggerating them.
State where keys and possession may be surrendered.
Be signed by the landlord or a duly authorized representative.

Rule 70, Section 2 generally requires a lessor relying on nonpayment or breach to demand that the tenant pay or comply with the lease conditions and vacate. Unless the parties stipulated otherwise, the rule refers to failure to comply after 15 days for land or five days for buildings. Contractual notice and cure provisions may also apply and should be followed.

Serve the demand using the method specified in the lease and preserve proof. Rule 70 recognizes service on the tenant, service on a person found on the premises, or posting on the premises when no person is found. For evidentiary security, landlords often use more than one lawful method, such as personal delivery with acknowledgment and trackable registered mail or courier delivery.

A demand should not contain unsupported accusations or threats of arrest. Criminal liability does not arise merely because a contractual breach is alleged.

If the tenant disputes the accusation

The tenant should respond in writing and provide relevant supporting records. Depending on the facts, the response may explain that:

The lease does not prohibit subletting;
The person is a guest, relative, employee, or roommate rather than a subtenant;
The landlord previously consented;
The activity remains within the agreed use;
The alleged violation has been corrected;
The notice did not follow the lease;
The supposed evidence identifies a different unit or person; or
The landlord’s factual allegations are inaccurate.

A tenant should not ignore the notice even when it appears defective. Important documents and communications should be preserved immediately. If surrender is negotiated, the agreement should address the move-out date, keys, inspection, utilities, deposit, unpaid accounts, damage claims, and release of claims.

Barangay conciliation may be required first

Katarungang Pambarangay conciliation is a precondition to court action when the dispute falls within the lupon’s authority. It commonly applies when the real parties in interest are natural persons who actually reside in the same city or municipality.

Disputes involving real property are generally brought in the barangay where the property—or the larger portion of it—is located. If conciliation fails, the proper certificate to file action should be obtained before filing in court. Parties generally appear personally in barangay proceedings without lawyers, subject to the statutory exceptions for minors and persons who are incompetent.

Barangay conciliation does not apply in every rental dispute. Important exceptions include disputes between parties actually residing in different cities or municipalities, unless adjoining-barangay rules and agreement apply; cases involving juridical entities in circumstances outside lupon authority; specified government-related disputes; and situations requiring urgent legal action to prevent injustice. The parties’ actual residences and legal identities—not merely the property address or business address—must be checked.

Skipping mandatory conciliation can result in dismissal or suspension of a prematurely filed case.

Filing an unlawful-detainer case

If lawful termination and demand do not produce surrender, the landlord may file unlawful detainer in the Municipal Trial Court, Metropolitan Trial Court, Municipal Circuit Trial Court, or Municipal Trial Court in Cities with territorial jurisdiction over the property.

Unlawful detainer concerns the right to physical possession. The tenant’s possession was lawful at the beginning but became unlawful after the right to possess expired or was validly terminated and the tenant refused to leave.

The complaint should accurately allege and support:

The parties’ identities and residences;
The plaintiff’s right to possession;
The lease and relevant restriction;
The acts constituting the breach;
Proper termination and demand;
The tenant’s failure to comply and surrender;
Compliance with barangay conciliation, when required; and
Filing within the Rule 70 period.

An unlawful-detainer action must be brought within one year from the unlawful withholding. Supreme Court decisions commonly reckon that period from the relevant demand to vacate. A later letter that merely repeats an earlier demand may not restart the period. Waiting close to one year is therefore dangerous. If the Rule 70 period has passed, a different possessory action may be necessary and should be assessed by counsel.

Ejectment cases filed from 11 April 2022 are governed by the Rules on Expedited Procedures in the First Level Courts. Among other things, a defendant generally has 30 calendar days from service of summons to file an answer. Because defenses, counterclaims, affidavits, and documents may be lost or excluded if not raised or submitted on time, both sides should seek legal assistance promptly after summons is served.

The court may award possession and appropriate compensation for the use and occupation of the property. Claims for other damages or attorney’s fees require a valid legal and evidentiary basis; they are not automatic simply because the lease mentions them.

Do not use self-help eviction

Even when the breach appears obvious, a landlord should not:

Change locks while the occupants are away;
Block access to the property;
Remove or dispose of belongings;
Shut off utilities as pressure to leave;
Use guards or other persons to intimidate occupants;
Enter without contractual or legal authority;
Publicly shame the tenant or disclose unnecessary personal information; or
Threaten arrest merely to collect rent or enforce a civil lease.

Articles 536 and 539 of the Civil Code protect possession against forcible interference and contemplate recourse to competent authorities or courts when possession is disputed. Unlawful self-help can expose the landlord to damages, injunctions, or other liability and may seriously weaken an otherwise valid case.

An immediate report to police, fire services, building officials, or another competent agency may be appropriate when there is an actual emergency, violence, fire hazard, or suspected crime. Such a report does not itself authorize a private lockout or determine the parties’ civil right to possession.

Options short of litigation

Depending on the seriousness of the breach, the parties may agree to:

Remove the unauthorized occupant;
Stop the prohibited activity by a fixed date;
Apply for written consent subject to reasonable conditions;
Amend the lease to identify occupants or an approved use;
Pay documented additional costs;
Repair damage and permit a lawful follow-up inspection;
End the lease voluntarily under a written surrender agreement; or
Set a realistic move-out schedule with safeguards against further damage.

Any settlement should be written, identify the people bound by it, state exact deadlines, and explain what happens to deposits, rent, utilities, repairs, keys, and remaining claims. A barangay settlement that becomes final has legal consequences and should not be signed casually.

Common mistakes

Assuming every additional occupant is a subtenant

Payment, control of space, permanence, and the parties’ actual agreement matter. A visitor or relative is not automatically a sublessee.

Overlooking the Civil Code’s default rule

If there is no express prohibition, subletting is generally allowed. Assignment remains subject to a different rule.

Sending only a notice to “explain”

For a breach-based unlawful-detainer case, a vague complaint or warning may not satisfy the required demand to comply and vacate.

Demanding only payment or compliance

The demand should ordinarily include surrender of possession if the breach remains unresolved. The wording of the lease and the ground invoked must be considered.

Relying on unverified screenshots or hearsay

Preserve URLs, dates, account details, original files, and witnesses with firsthand knowledge. Confirm that the material relates to the correct property.

Repeatedly sending demands and assuming the deadline restarts

A repetitive reminder may not create a fresh one-year Rule 70 period.

Skipping barangay proceedings

Determine whether the parties’ actual residences and legal status place the dispute within lupon authority.

Accepting rent without documenting the landlord’s position

Continued acceptance with knowledge of the alleged breach can complicate arguments about consent or waiver. Obtain advice on how to handle tendered payments lawfully.

Treating a civil breach as a crime

Unauthorized subletting or nonpayment is not, by itself, proof of a criminal offense. Report only conduct for which there is a good-faith factual and legal basis.

When legal help is urgent

Consult a Philippine lawyer promptly when:

A demand has already been served and the one-year ejectment period is running;
Summons or a court order has been received;
The lease is oral, incomplete, or internally inconsistent;
The landlord previously knew of or consented to the arrangement;
The property is being used for short-term rentals or a regulated business;
Several occupants or corporate parties are involved;
The tenant claims ownership, a right to purchase, or another independent right to possess;
There is substantial property damage or a safety hazard;
Either side is considering changing locks, removing belongings, or cutting utilities;
A barangay settlement is being proposed;
There are threats, violence, suspected criminal activity, or an immediate danger; or
The property is subject to condominium, socialized-housing, government, or specialized regulatory rules.

FAQ

Can a tenant sublease without asking the landlord?

Generally, yes, if the lease contains no express prohibition against subletting. The tenant remains responsible to the landlord. Assignment of the lease is different and generally requires the landlord’s consent unless the contract provides otherwise.

Is a “no assignment” clause automatically a “no sublease” clause?

Not necessarily. Assignment and sublease are legally distinct. The exact language and actual transaction must be examined.

Can the landlord evict the subtenant directly?

The landlord may seek recovery against persons unlawfully withholding possession or claiming under the tenant, but the correct defendants and allegations depend on the lease, the sublease, occupancy, and demand. The tenant and relevant occupants should be identified before filing.

Does accepting rent legalize the prohibited arrangement?

Not automatically. But knowing acceptance, communications, and repeated conduct may support arguments about consent, waiver, or modification. The facts must be evaluated together.

Can the tenant cure the breach by removing the subtenant?

Possibly, especially when the lease provides a cure period or the demand allows compliance. Cure may not resolve every case—for example, if the lease was validly terminated, the breach caused substantial damage, or the contract makes the violation a ground for termination. The wording and circumstances control.

Can the landlord enter the unit to gather evidence?

Only with lawful authority, such as valid consent, a lease-compliant inspection right exercised with proper notice, or a genuine emergency. Ownership does not give an unrestricted right to enter an occupied rental property.

Can the landlord immediately change the locks after the lease is terminated?

Ordinarily, no. If occupants refuse to surrender possession, the landlord should obtain relief through the proper legal process.

Where is the ejectment case filed?

In the proper first-level court with territorial jurisdiction over the property. Mandatory barangay conciliation must be completed first when applicable.

What if more than one year has passed since the demand?

Summary unlawful detainer may no longer be available. Another action to recover possession may be appropriate, but jurisdiction, allegations, and remedies differ. Obtain legal advice without further delay.
