When a buyer has already moved into a house, lot, or condominium but stops paying the remaining purchase price, the seller cannot simply change the locks, remove the buyer’s belongings, or ask the police to evict the buyer. The correct remedy depends on the contract, how much the buyer has paid, whether ownership has already transferred, and whether the seller has properly cancelled or rescinded the transaction. A mistake at the demand-letter stage can delay recovery of the property or cause an ejectment case to be dismissed.

First Determine What Kind of Property Contract You Have

The document’s title is not controlling. Courts examine its actual terms, especially when ownership was supposed to transfer.

Contract or arrangement	Usual legal effect	Typical remedy for nonpayment
Contract to sell	The seller retains ownership until the buyer fully pays the price or satisfies another condition	Valid cancellation, compliance with the Maceda Law when applicable, demand to vacate, then ejectment
Contract of sale or deed of absolute sale	Ownership may have passed upon delivery, even if part of the price remains unpaid	Collection of the balance or judicial rescission and restoration of ownership
Installment sale by a subdivision or condominium developer	Governed by the contract, the Maceda Law, and possibly Presidential Decree No. 957	Statutory grace periods and cancellation procedures; DHSUD or HSAC issues may also arise
Lease with option to buy	Occupancy may initially be based on a lease rather than a sale	Lease termination, collection, or ejectment depending on the agreement
Conditional deed or memorandum of agreement	Effect depends on whether full payment is a condition before ownership transfers	Contract interpretation is essential before demanding surrender

A provision stating that the deed of absolute sale will be signed only after full payment is a strong indication of a contract to sell. In Diego v. Diego, the Supreme Court treated such a provision as a distinctive sign that the seller retained ownership pending full payment. (Supreme Court E-Library)

This distinction matters because nonpayment under a contract to sell generally prevents the seller’s obligation to transfer ownership from becoming effective. By contrast, when there has already been a completed sale, the seller may need to seek judicial rescission rather than merely declare that the buyer has lost all rights.

The Seller’s Main Legal Options

1. Demand payment of the unpaid balance

Under Article 1191 of the Civil Code of the Philippines, the injured party in a reciprocal contract may generally choose between:

Fulfillment, meaning enforcement of the buyer’s obligation to pay; or
Resolution or rescission, meaning cancellation of the reciprocal obligations because of a substantial breach.

Damages may be claimed with either remedy when legally and factually supported.

A seller who still wants the transaction completed may demand:

The principal balance;
Contractual interest, if validly agreed upon;
Penalties or liquidated damages, subject to possible reduction if excessive;
Taxes, association dues, or expenses assigned to the buyer by the contract; and
Reasonable attorney’s fees when authorized by the contract or law.

If there is no valid stipulated interest, Article 2209 and the doctrine in Nacar v. Gallery Frames generally support legal interest at 6% per year on a monetary obligation after the debtor is placed in delay through judicial or extrajudicial demand. (Lawphil)

2. Cancel or rescind the transaction and recover possession

A seller who no longer wants to continue the transaction may seek cancellation or rescission, return or retention of payments as legally allowed, and recovery of possession.

For a completed sale of real property, Article 1592 of the Civil Code is especially important. Even when the contract says cancellation will occur automatically upon nonpayment, the buyer may generally still pay after the deadline until the seller makes a judicial demand or a demand through a notarial act for rescission. After that demand, a court may no longer grant the buyer a new payment period under Article 1592. (Lawphil)

Article 1592 ordinarily applies to a sale of immovable property, not to a true contract to sell in which ownership was expressly reserved. The Supreme Court reiterated this distinction in Royal Plains View, Inc. v. Mejia. (Supreme Court E-Library)

However, calling the agreement a contract to sell does not allow the seller to ignore the Maceda Law.

3. Negotiate a voluntary surrender or restructuring

Litigation may be avoided through a written agreement covering:

A final payment schedule;
A fixed voluntary move-out date;
Treatment of previous payments;
Cash surrender value or refund, if required;
Reasonable compensation for continued occupancy;
Condition of the property upon turnover;
Transfer of utilities and association accounts;
Delivery of keys and an inventory of fixtures; and
Release of claims only after both sides have performed.

A compromise involving real property should be written clearly and notarized. Acceptance of late or partial payments after an announced cancellation should also be documented carefully because it may create an argument that the seller waived the default or revived the agreement.

When the Maceda Law Applies

Republic Act No. 6552, known as the Realty Installment Buyer Protection Act or Maceda Law, protects buyers of real estate on installment payments.

It generally covers residential real estate installment transactions, including condominium units. It excludes:

Industrial lots;
Commercial buildings; and
Sales to agricultural tenants under Republic Act No. 3844.

The law’s protections cannot be defeated by simply placing an automatic-cancellation clause in the contract.

If the buyer has paid less than two years of installments

The buyer is entitled to:

A grace period of at least 60 days, counted from the date the unpaid installment became due; and
If the buyer still fails to pay, cancellation only after 30 days from the buyer’s receipt of a notice of cancellation or demand for rescission made through a notarial act.

An ordinary text message, email, verbal demand, or unnotarized lawyer’s letter may not satisfy this statutory cancellation requirement.

If the buyer has paid at least two years of installments

The buyer is entitled to:

A grace period of one month for every year of installment payments made, without additional interest;
Use of that statutory grace period once every five years during the contract, unless the agreement grants better rights;
A notarial notice of cancellation or demand for rescission;
At least 30 days from receipt of the notarial notice; and
Payment of the required cash surrender value before cancellation becomes effective.

The cash surrender value is normally:

50% of total payments made; plus
After five years of installments, an additional 5% for every year, up to a maximum of 90%.

Down payments, deposits, and option money are included in total payments for this computation when covered by the law. The statutory text makes cancellation effective only after both the 30-day period and payment of the required cash surrender value. (Lawphil)

In Spouses Bayudan v. Dacayan, the Supreme Court held that sellers could not maintain an unlawful detainer case where the contract to sell had not been validly cancelled under the Maceda Law. Without effective cancellation, the buyer’s continued possession had not yet become unlawful. (Supreme Court E-Library)

Check Whether the Buyer Has a Valid Reason for Suspending Payment

Not every unpaid balance is a straightforward buyer default. Before cancelling, determine whether the seller or developer failed to perform an earlier obligation.

Possible buyer defenses include:

The seller cannot produce a clean title;
The property is subject to an undisclosed mortgage, adverse claim, or pending case;
The seller failed to deliver possession as agreed;
The property substantially differs from the approved plan or description;
A developer failed to complete roads, drainage, water systems, amenities, or other promised improvements;
The unit or subdivision lacks required approvals;
The buyer is being disturbed by a reivindicatory ownership claim or foreclosure; or
The seller accepted a revised payment arrangement.

Under Article 1590 of the Civil Code, a buyer may suspend payment when disturbed in possession or ownership by a vindicatory action or foreclosure, subject to the article’s conditions. Mere trespass or an unsupported fear of a future claim is not automatically enough.

For subdivision and condominium projects, Section 23 of Presidential Decree No. 957 permits a buyer, after due notice, to suspend installment payments when the owner or developer fails to develop the project according to the approved plans and within the required period. The buyer may also pursue reimbursement in proper circumstances. (Lawphil)

A buyer cannot ordinarily stop paying merely because of financial difficulty, buyer’s remorse, or a change in market value. The alleged justification should be matched against the contract, title records, approved development plans, correspondence, and actual condition of the property.

Step-by-Step Process for the Seller

1. Secure the complete documentary record

Collect the signed contract and every document showing what each party promised. Do not rely only on a payment spreadsheet or informal messages.

At minimum, obtain:

Contract to sell, deed of sale, reservation agreement, or memorandum of agreement;
Addenda, restructuring agreements, and turnover documents;
Certified true copy of the Transfer Certificate of Title or Condominium Certificate of Title;
Tax declaration and real property tax records;
Payment ledger, receipts, bank records, and returned checks;
Proof of the buyer’s possession and date of turnover;
Correspondence about extensions, defects, or revised payment terms; and
Developer approvals, license to sell, plans, and completion commitments when applicable.

2. Prepare an accurate statement of account

The computation should separate:

Original selling price;
Payments received;
Principal balance;
Interest;
Penalties;
Taxes and association dues;
Credits or refunds; and
Maceda Law cash surrender value, when required.

Do not add undocumented charges. Courts may reject penalties that have no contractual basis or reduce penalties that are unconscionable.

3. Decide which remedy the seller is choosing

The demand should make the seller’s position understandable.

A seller may initially give the buyer a final opportunity to cure the default and state that failure will lead to cancellation. But the seller should avoid simultaneously asserting that:

The contract has already been cancelled;
The entire purchase price remains immediately collectible; and
The buyer must continue performing the supposedly cancelled contract.

Alternative remedies may be pleaded in court when procedurally allowed, but the factual and legal theory must remain coherent.

4. Complete the required grace periods

Before issuing a final cancellation:

Determine whether the Maceda Law applies;
Count the buyer’s installment-payment years correctly;
Identify the original due date;
Account for written extensions or accepted late-payment practices; and
Calculate any mandatory refund.

A seller should not treat the statutory 30-day period as running from mailing. The Maceda Law refers to the buyer’s receipt of the notarial notice.

5. Serve a formal demand and notarial cancellation notice

The notice should contain:

Names and addresses of the parties;
Exact property description;
Contract date and relevant provisions;
Payment history and outstanding balance;
Specific default;
Applicable grace periods;
Final date for payment;
Declaration of cancellation or demand for rescission, when appropriate;
Cash surrender value and manner of payment, if required;
Demand to vacate after cancellation becomes effective; and
Reservation of claims for damages and reasonable use of the property.

Use reliable methods that produce evidence of delivery:

Personal service with a signed receiving copy;
Registered mail with registry receipt and return card;
Reputable courier with delivery certification; and
Email or messaging applications as supplementary proof.

A buyer’s refusal to receive the notice should be documented through the process server, courier records, witnesses, photographs, or an affidavit of attempted service.

6. Complete barangay conciliation when required

Under the Local Government Code, disputes between natural persons actually residing in the same city or municipality generally must first undergo Katarungang Pambarangay proceedings, unless an exception applies.

The usual process is:

Mediation before the Punong Barangay;
Constitution of the Pangkat Tagapagkasundo if mediation fails;
Pangkat conciliation, normally for up to 15 days, extendible by another 15 days in meritorious cases; and
Issuance of a Certificate to File Action if no settlement is reached.

Cases involving corporations, parties residing in different cities or municipalities, urgent provisional remedies, or other statutory exceptions may not require prior barangay conciliation. Filing without a required Certificate to File Action can result in dismissal or premature litigation. (Lawphil)

7. File the correct court action

The appropriate case depends on the desired result.

Seller’s objective	Possible action	Usual forum
Collect money only, not exceeding ₱1 million	Small claims case, if the claim qualifies	First-level court
Collect a civil claim within first-level court jurisdiction	Civil action under summary or regular procedure, depending on the claim	MeTC, MTCC, MTC, or MCTC
Recover possession within one year from the effective demand to vacate	Unlawful detainer	First-level court
Recover possession after the one-year ejectment period	Accion publiciana	First-level court or RTC, based on assessed value
Rescind a completed sale, restore title, or obtain reconveyance	Action for rescission, cancellation, or reconveyance	Frequently the RTC, depending on the principal relief
Resolve certain subdivision or condominium buyer claims against a developer	Administrative case within statutory jurisdiction	Human Settlements Adjudication Commission

Under Republic Act No. 11576, first-level courts generally handle civil money claims not exceeding ₱2 million, exclusive of specified incidental amounts. For actions involving title to or possession of real property, jurisdiction between the first-level court and RTC generally turns on whether the property’s assessed value exceeds ₱400,000. Ejectment cases remain within the exclusive original jurisdiction of first-level courts regardless of assessed value. (Lawphil)

A small claims case is appropriate only when the seller seeks payment of a qualifying money claim. It cannot provide the full relief needed when the central issues include cancellation, title, reconveyance, or possession.

8. Enforce the judgment through the sheriff

Winning a case does not authorize private eviction. If the buyer still refuses to leave, the court issues a writ of execution, and the sheriff implements the judgment.

The sheriff may:

Serve the writ;
Direct the occupants to vacate;
Coordinate lawful turnover;
Remove occupants and personal property under court procedures; and
Deliver possession to the prevailing party.

Property condition, fixtures, keys, meter readings, and abandoned belongings should be documented during turnover.

Requirements for an Unlawful Detainer Case

Unlawful detainer is commonly used when the buyer originally entered lawfully but later lost the right to remain.

The seller generally must show:

The buyer’s possession was initially lawful;
The contract or right to possess was validly terminated;
The seller demanded that the buyer vacate;
The buyer continued occupying the property; and
The case was filed within one year from the operative demand that made possession unlawful.

The case must allege these facts clearly. It is not enough to say that the seller owns the property and the buyer has failed to pay.

In Rivera-Avante v. Rivera, the Supreme Court explained that ejectment concerns physical possession and that ownership is considered only provisionally when necessary to decide who has the better right to possess. The decision also warns that repeated reminder letters do not necessarily restart the one-year filing period. Count conservatively from the first effective demand following valid termination. (Supreme Court E-Library)

Under the Supreme Court’s Rules on Expedited Procedures in the First Level Courts, all forcible entry and unlawful detainer cases use summary procedure regardless of the damages or unpaid rentals claimed. The defendant generally has 30 calendar days from service of summons to answer. (Supreme Court of the Philippines)

Although the procedural rules prescribe short periods, actual completion may still take several months or longer because of service problems, failed mediation, court congestion, motions, appeals, and enforcement difficulties.

Common Mistakes That Can Weaken the Seller’s Case

Changing the locks or cutting utilities

Self-help eviction can expose the seller to civil liability, injunctions, damages, or criminal complaints. The buyer entered with permission, so forcible removal is not the proper first remedy.

Treating nonpayment as automatically criminal

Failure to pay a contractual debt is generally a civil matter. Estafa requires additional elements such as deceit or misappropriation; it does not arise simply because the buyer later lacked funds.

A dishonored check may create liability under Batas Pambansa Blg. 22 only when all statutory elements are proven, including proper notice of dishonor and failure to pay or make arrangements within five banking days from receipt of notice. (Lawphil)

Using an ordinary demand when a notarial notice is required

For covered installment sales, the Maceda Law requires cancellation or demand for rescission through a notarial act. Proof that the buyer received it is as important as notarization.

Filing ejectment before valid cancellation

If the contract remains effective, the buyer may still have a contractual right to occupy. Premature ejectment can be dismissed even when installments are unpaid.

Missing the one-year ejectment period

A seller who waits more than one year after the effective demand may need to file an accion publiciana instead. That action is generally more complex than summary ejectment.

Assuming all previous payments may be forfeited

A forfeiture clause remains subject to the Maceda Law, Civil Code provisions, and equitable review. Where the buyer has paid at least two years of installments, the statutory cash surrender value cannot simply be ignored.

Filing in the wrong forum

The dispute may involve an MTC, RTC, or the Human Settlements Adjudication Commission depending on the parties, property, assessed value, and principal relief. The former HLURB’s adjudicatory functions are now exercised by the HSAC under Republic Act No. 11201, but not every developer-versus-buyer collection or possession case falls within its jurisdiction. (Lawphil)

Documents Commonly Needed

Document	Why it matters
Contract to sell or deed of sale	Establishes payment terms, ownership conditions, and remedies
Certified title copy	Confirms registered owner, liens, mortgages, and annotations
Tax declaration	Shows assessed value for jurisdictional purposes
Payment ledger and receipts	Proves default and total payments made
Returned checks and bank notices	Supports collection and possible BP 22 issues
Turnover or occupancy agreement	Establishes when and why possession began
Notarial cancellation notice	Proves compliance with Article 1592 or the Maceda Law
Proof of receipt	Establishes when statutory and ejectment periods began
Cash surrender computation and proof of payment or tender	Necessary for covered buyers who paid at least two years
Barangay Certificate to File Action	Shows compliance with mandatory conciliation
Photographs, utility records, and association records	Proves continued occupancy and property condition
Corporate secretary’s certificate or board authority	Establishes authority when the seller is a corporation
Special power of attorney	Allows a representative to act for an absent seller

Court filing fees vary according to the action, claim amount, assessed value, and damages requested. The Clerk of Court computes the official filing fee. Separate expenses may include certified records, notarization, courier service, sheriff’s fees, publication in unusual cases, and enforcement costs.

Special Issues for Sellers or Buyers Abroad

A seller abroad may authorize a representative through a special power of attorney. When the SPA is executed in another country, it will commonly need:

Notarization in that country;
An apostille from the country’s competent authority if it is a party to the Apostille Convention; or
Philippine consular authentication when the relevant document cannot use the apostille process.

The original authenticated or apostilled instrument may be required by courts, registries, banks, or government offices. (Philippine Embassy)

Where the buyer is a foreigner, the validity of the intended transfer must also be examined. Article XII, Section 7 of the 1987 Constitution generally prohibits foreigners from acquiring private land except through hereditary succession. Foreigners may acquire qualifying condominium units subject to the Condominium Act and the project’s foreign ownership ceiling. A constitutionally prohibited land transaction may require restitution or another remedy rather than an order compelling transfer of the land. (Lawphil)

Frequently Asked Questions

Can the seller immediately remove a buyer who stopped paying?

No. The buyer originally entered with the seller’s consent. The seller must first establish default, observe applicable grace periods, validly cancel or rescind the agreement, demand that the buyer vacate, and obtain a court order if the buyer refuses.

Is a text message demanding payment enough?

It may help prove that the buyer knew about the default, but it may not satisfy Article 1592 or the Maceda Law. When a notarial demand is required, use a notarized notice and preserve proof of receipt.

Can the seller keep every payment already made?

Not automatically. The contract, Maceda Law, amount and duration of payments, damages suffered, and fairness of any forfeiture provision must be considered. Buyers who paid at least two years of installments may be entitled to a statutory cash surrender value.

What happens if the buyer paid installments for less than two years?

For a transaction covered by the Maceda Law, the buyer ordinarily receives a 60-day grace period from the due date. Cancellation may occur only after another 30 days from receipt of the required notarial notice.

What if a deed of absolute sale has already been signed?

The seller may no longer be dealing with a simple contract-to-sell cancellation. Depending on delivery, registration, and the deed’s terms, the remedies may include collection of the unpaid balance, judicial rescission, reconveyance, cancellation of title, and damages.

Can the seller charge rent while the defaulting buyer remains in the property?

The seller may claim reasonable compensation for use and occupancy after the buyer’s right to possess has validly ended. The amount should have a contractual or evidentiary basis. Calling it “rent” does not by itself create a lease.

Does a bounced check allow immediate eviction?

No. A bounced check may support a money claim and, when all elements exist, a BP 22 complaint. It does not replace contractual cancellation, demand to vacate, or an ejectment judgment.

How long does an ejectment case take?

The procedural rules are designed for expedited resolution, but actual timelines vary. Service of summons, barangay proceedings, mediation, court workload, appeal, and sheriff implementation can extend the process from several months to considerably longer.

Should the case be filed with DHSUD or HSAC?

DHSUD handles housing regulation, while HSAC adjudicates disputes assigned to it by law. Certain claims by subdivision or condominium buyers against developers fall within HSAC jurisdiction. A seller’s collection, cancellation, or ejectment claim may instead belong in the regular courts, depending on the principal relief.

What can a seller do when the one-year ejectment deadline has passed?

The seller may pursue an accion publiciana to recover the better right of possession. Jurisdiction will generally depend on the property’s assessed value under Republic Act No. 11576.
