Introduction

In the Philippines, an action for Unlawful Detainer (commonly referred to as an ejectment suit) is a legal remedy available to a person deprived of the possession of real property. It is governed primarily by Rule 70 of the Rules of Court (on Ejectment) and the Revised Rules on Summary Procedure for cases filed in first-level courts (i.e., Metropolitan Trial Courts, Municipal Trial Courts in Cities, Municipal Trial Courts, and Municipal Circuit Trial Courts). The essence of Unlawful Detainer is that the defendant originally had lawful possession of the property—often as a lessee, vendee, or other occupant permitted by the owner or lessor—but subsequently defied a demand to vacate after the right to continue possessing the property had terminated.

This article explains the basics of Unlawful Detainer in the Philippine context, focusing on what evidence is required to successfully prosecute (or defend) such a case.

Unlawful Detainer vs. Forcible Entry

Before delving into the evidence requirements, it is crucial to distinguish Unlawful Detainer from Forcible Entry:

Forcible Entry (Rule 70, Section 1, Rules of Court) involves the use of force, intimidation, threats, strategy, or stealth in gaining possession of the property.
Unlawful Detainer (Rule 70, Section 2, Rules of Court) involves the possession of the property initially granted by the owner or lawful possessor, which is later unlawfully withheld after the expiration or termination of the right to possess.

The evidence requirements for ejectment actions largely parallel each other, but the factual allegations and proofs differ because the “cause” of lost possession is different: forcible entry centers on the manner by which possession was taken, while unlawful detainer concerns the continued possession after the permission to possess expires.

Key Elements of Unlawful Detainer

To succeed in an Unlawful Detainer case, the plaintiff (landlord or owner) must generally prove the following elements:

Initial Lawful Possession
The defendant’s possession of the property was initially lawful or tolerated, often by virtue of a lease agreement (written or oral), verbal consent, or implied permission.
Expiration or Termination of Possession
The continued occupation became unlawful upon the expiration of the lease or the revocation of the right to possess. This may happen when:
- The lease period ends.
- The occupant fails to pay rent or violates other lease conditions.
- The owner or lawful possessor demands the occupant to vacate or otherwise terminates the arrangement.
Demand to Vacate
A valid, sufficient, and timely demand to vacate must have been made by the plaintiff. Under the Rules on Summary Procedure, a written demand is usually required.
Refusal to Vacate
The occupant (defendant) refused to leave after receiving the demand, hence becoming an unlawful detainer.
Filing Within One Year
The ejectment case must be filed within one year from the date of the last demand (or from the time the right of possession was effectively terminated). Failure to meet this deadline may result in dismissal of the ejectment suit, and the parties might have to resolve the dispute through other legal actions (e.g., accion publiciana or accion reivindicatoria).

Evidence Requirements in Unlawful Detainer

1. Proof of Ownership or Legal Possession

Although Unlawful Detainer is essentially an action to recover possession (not necessarily to prove ownership), plaintiffs typically present proof of ownership (e.g., a Torrens title, tax declarations, deed of sale) or evidence of a better right of possession (e.g., lease agreement). While absolute title is not the main issue in Unlawful Detainer suits, showing some right or interest in the property that is superior to the defendant’s can strengthen the plaintiff’s case.

Note: Even if the plaintiff is not the registered owner but has the right to possess (for instance, a lessee subletting with contractual authority), they can still maintain an Unlawful Detainer action.

2. Proof of Lease or Tolerance

A written or oral contract of lease (if the occupant is a tenant) or evidence that demonstrates the owner tolerated the defendant’s occupancy is critical. Common forms of documentary evidence include:

Lease agreements
Payment receipts of monthly rental or deposit fees
Written statements or communications acknowledging the occupant’s right to stay

Even lacking a written lease, the court can deduce lawful possession if the plaintiff can show the occupant regularly paid rent or that the occupant paid certain amounts in acknowledgment of the plaintiff’s property right.

3. Demand Letters and Proof of Service

The plaintiff must prove they have made a formal demand to vacate and that the defendant refused to comply. Essential pieces of evidence typically include:

Demand Letter: A written notice addressed to the occupant stating the ground for termination and giving them a definite period to vacate.
Proof of Service: Evidence that the demand letter was actually received by or otherwise served on the defendant. This can take the form of:
- An affidavit of the person who delivered the letter
- Registered mail registry receipts or return cards
- Acknowledgment receipts signed by the occupant

4. Affidavits of Witnesses

Because Unlawful Detainer actions often proceed under the Revised Rules on Summary Procedure, the rules typically require the submission of affidavits of witnesses and other documentary evidence upfront. These affidavits serve as direct testimonies in lieu of a full-blown trial, though cross-examination might still be requested in certain circumstances. The plaintiff should present affidavits attesting to:

The nature of the lease agreement or permission
The fact of termination or expiry of the lease
The refusal of the defendant to comply with the demand to vacate

5. Rental/Payment Records

If non-payment of rent or overdue rent is a ground for ejectment, the plaintiff should include rent receipts, records of bounced checks, or any evidence showing the defendant’s delinquency or the cessation of rental payments.

6. Certification Against Forum Shopping

Under Philippine procedural rules, a Certificate of Non-Forum Shopping must be appended to the Complaint. This certifies that the plaintiff (and counsel) have not commenced any other action or proceeding involving the same issues and that there is no pending action in any court or tribunal.

Initiating the Action

1. Where to File

Unlawful Detainer actions are filed in the Municipal Trial Court (MTC), Municipal Trial Court in Cities (MTCC), Metropolitan Trial Court (MeTC), or Municipal Circuit Trial Court having territorial jurisdiction over the location of the property.

2. Complaint Requirements

The complaint must detail:

A statement of the plaintiff’s right to possession or the circumstances of toleration.
The expiration or termination of the defendant’s possession.
The fact and date of demand to vacate.
The defendant’s continued occupancy.
Compliance with the one-year prescriptive period (action must be filed within one year from last demand).
The prayed-for relief (e.g., surrender of property, arrears in rent, costs of suit).

All supporting evidence (e.g., demand letter, affidavits) is best attached to the complaint, especially under the Revised Rules on Summary Procedure.

3. Defendant’s Answer

The defendant may file an Answer within the period stipulated by the Summary Procedure rules (a shorter period than in ordinary civil actions). The Answer must be verified and include all defenses (factual or legal) plus supporting affidavits and documents. The defendant’s failure to raise critical defenses or to submit crucial evidence at this stage might weaken their position.

Trial and Judgment

Under the Revised Rules on Summary Procedure, Unlawful Detainer cases generally proceed in an expedited manner:

After the plaintiff files the complaint and the defendant files the answer, the court may call the parties to a preliminary conference or judicial dispute resolution conference.
If settlement fails, the court may allow the parties to submit position papers or memoranda with attached evidence (no extensive trial by witness examination except in limited circumstances where clarifications or cross-examinations are needed).
The court should render judgment based on the pleadings, evidence presented, and applicable law within a shortened timeframe.

Possible Court Rulings

Grant of Ejectment: Defendant is ordered to vacate and pay arrears in rent or reasonable compensation for the use of the property.
Denial of Ejectment: If the court finds the plaintiff failed to meet the burden of proving unlawful detainer, the case is dismissed.

Post-Judgment Remedies

Appeal
A losing party may appeal the MTC/MeTC/MTCC’s judgment to the Regional Trial Court (RTC) within the period specified by the Rules of Court. The RTC’s decision may in turn be elevated to the Court of Appeals or ultimately the Supreme Court if justified by legal grounds.
Execution
If no appeal is made or if the judgment is affirmed on appeal, the court may issue a writ of execution ordering the sheriff to enforce the decision—i.e., physically oust the defendant if they refuse to leave and collect any money judgment awarded (unpaid rent, damages, costs).

Common Defenses by the Defendant

No Valid Lease Termination: Arguing that the lease or right of possession has not yet expired, or that termination was invalid (e.g., no proper notice).
Wrongful Demand: Arguing that the plaintiff’s demand to vacate was not served properly, was defective, or was never received.
Ownership Issues: Questioning the plaintiff’s title, although full-blown ownership disputes are generally outside the scope of Unlawful Detainer. Still, the defendant might raise doubts about whether the plaintiff is indeed the proper party to evict.
Laches or Prescription: Arguing that the plaintiff filed the case beyond the one-year prescriptive period for ejectment suits.

Important Points and Practical Tips

Proactive Documentation
The property owner/landlord should keep thorough records: written contracts, receipts, and timely demand letters. If the occupant fails to pay rent on time, do not wait too long to issue a notice; the one-year period could lapse, resulting in a more complicated case of accion publiciana or accion reivindicatoria, which takes longer and is more expensive.
Proper Notice to Vacate
Even if a contract of lease stipulates automatic termination after a certain event, the law still often requires a demand to vacate to trigger an unlawful detainer action. Serve notices in writing, preferably through registered mail or with a signed acknowledgment of receipt.
Compliance with Procedural Rules
Because ejectment suits follow the Summary Procedure, strict compliance with the rules—particularly regarding pleading, evidence submission, and timelines—is critical. Failure to comply can result in dismissal.
One-Year Deadline
Unlawful detainer is a summary remedy intended for quick recovery of possession. Do not delay beyond the one-year mark from the last demand, or risk losing the right to bring an ejectment action under Rule 70.
Retention of Counsel
While the Summary Procedure is designed to be simpler than ordinary civil actions, professional guidance from a lawyer can be invaluable to ensure the correct framing of the complaint or answer, timely submission of evidence, and observance of procedural rules.

Conclusion

Unlawful Detainer in the Philippines provides an expedited remedy for landlords or lawful possessors to regain possession of property when an occupant remains despite the expiration or termination of their right to stay. The crux of an Unlawful Detainer suit lies in proving that the possession was initially lawful, the right to possess has ended, and a demand to vacate was made and refused. Evidentiary requirements—such as the lease agreement, demand letters, proof of service, and relevant affidavits—must be well-prepared and submitted in compliance with the Revised Rules on Summary Procedure.

Anyone dealing with a potential Unlawful Detainer issue—whether as landlord or occupant—is strongly advised to seek qualified legal counsel. Legal advice from an attorney ensures all necessary evidence is presented correctly, procedural rules are met, and rights are preserved to the fullest extent of the law.
