When a buyer moves into a house, lot, condo unit, or other property before paying the full purchase price, the problem is usually not just “unpaid balance.” It becomes a possession problem, a contract problem, and sometimes a title problem. The right move depends on what was signed, whether ownership was already transferred, whether the buyer is protected by the Maceda Law, and whether the buyer’s possession has already become unlawful. The safest approach is to review the documents first, make a proper written demand, avoid self-help eviction, and use the correct forum if the buyer refuses to pay or leave.

Why early occupancy is risky

Allowing a buyer to occupy before full payment often feels practical. The buyer may need to move in, renovate, secure the property, or show good faith. But in Philippine real estate transactions, possession has legal consequences.

The main risks are:

The buyer may claim that delivery already transferred ownership.
The seller may find it harder to recover possession quickly.
The buyer may stop paying but continue living in the property.
Utilities, association dues, real property tax, and repairs may become disputed.
If the documents were poorly drafted, the case may turn into a long civil action instead of a faster ejectment case.
If the seller uses force, padlocks the property, cuts utilities, or removes belongings, the seller may face separate complaints.

The first question is simple but critical: did you sign a contract of sale, a contract to sell, or only an occupancy agreement?

Check the type of agreement first

Philippine law treats these arrangements differently.

Document or arrangement	Usual legal effect	Why it matters
Deed of Absolute Sale	Usually indicates that the seller already agreed to transfer ownership, especially if delivery was made	The seller may need rescission or collection remedies, not simple cancellation
Contract to Sell	Seller keeps ownership until full payment	Buyer’s failure to fully pay may prevent the seller’s obligation to transfer title from arising
Conditional Sale	Depends on wording; may operate like a contract to sell or a conditional contract of sale	Courts look at the actual stipulations, not just the title of the document
Reservation Agreement	Usually preliminary; buyer may not yet have ownership or possessory rights	Seller must check if it gives any right to occupy
Occupancy Permit / Move-in Agreement	Buyer may enter only under stated conditions	This helps show that possession was temporary and conditional
Lease with Option to Buy	Buyer is also a tenant until purchase is completed	Non-payment may involve both lease and sale provisions

Under the Civil Code, ownership of the thing sold is generally transferred upon actual or constructive delivery, but the parties may stipulate that ownership will not pass until the buyer fully pays the price. (Lawphil)

This is why the exact wording matters. A clause saying “ownership shall remain with the seller until full payment” is very different from a notarized deed saying the seller has already sold, transferred, and conveyed the property.

Contract to sell vs. contract of sale

Contract to sell

A contract to sell is common in Philippine real estate transactions. The buyer pays in installments, but the seller keeps ownership until the full purchase price is paid.

The Supreme Court has repeatedly explained that in a contract to sell, full payment is a positive suspensive condition. This means the seller’s obligation to execute the deed of absolute sale or transfer title becomes demandable only after full payment. If the buyer does not fully pay, the seller’s obligation to convey ownership does not arise. (Supreme Court E-Library)

In practical terms, if the buyer occupies the property under a contract to sell and then defaults:

the buyer may not yet be the owner;
the seller may have a stronger basis to cancel or terminate, subject to the contract and applicable laws;
the buyer’s continued stay after valid demand may become unlawful;
ejectment may be available if the requirements are met.

Contract of sale or deed of absolute sale

A contract of sale is different. Under Article 1458 of the Civil Code, one party obligates himself to transfer ownership and deliver a determinate thing, while the other pays a price certain. The Civil Code also provides that delivery is important in transferring ownership. (Supreme Court E-Library)

If a deed of absolute sale was already signed and the buyer was placed in possession, the seller may have a harder case. The seller may need to pursue:

collection of the unpaid balance;
rescission under Article 1191 of the Civil Code;
rescission rules for immovable property under Article 1592;
damages, interest, and attorney’s fees if supported by the contract.

Article 1191 allows the injured party in reciprocal obligations to choose between fulfillment and rescission, with damages in either case. Article 1592 adds a special rule for sales of immovable property: even if the contract says rescission happens automatically upon non-payment, the buyer may still pay after the due date as long as no demand for rescission has been made judicially or by notarial act. (Lawphil)

This is one reason notarized demand letters matter in real estate disputes.

Is the buyer protected by the Maceda Law?

For real estate sold on installments, Republic Act No. 6552, known as the Realty Installment Buyer Act or Maceda Law, may apply. It protects buyers of real estate on installment payments against oppressive cancellation terms. (Lawphil)

If the buyer has paid at least two years of installments

The buyer is generally entitled to:

a grace period of one month for every year of installment payments made, without additional interest;
this grace period may be used only once every five years of the contract life and extensions;
if the contract is cancelled, a refund of the cash surrender value, generally 50% of total payments made, plus an additional 5% per year after five years of installments, up to 90%;
actual cancellation only after 30 days from receipt of the notice of cancellation or demand for rescission by notarial act, and upon full payment of the cash surrender value. (Lawphil)

If the buyer has paid less than two years of installments

The seller must give a grace period of at least 60 days from the date the installment became due. If the buyer still fails to pay, the seller may cancel after 30 days from the buyer’s receipt of a notice of cancellation or demand for rescission by notarial act. (Lawphil)

Why this matters before ejectment

If Maceda Law applies, cancellation done without the required notice, grace period, or refund may be attacked as invalid. A buyer in possession may argue that the contract is still alive and that the seller has not yet validly terminated the buyer’s right to occupy.

For sellers, this means: do not jump straight to eviction without checking Maceda Law compliance.

If the property is a subdivision lot or condominium unit

If the transaction involves a subdivision project or condominium project, additional rules may apply under Presidential Decree No. 957, the Subdivision and Condominium Buyers’ Protective Decree.

PD 957 requires, among others, registration of the project and a license to sell before subdivision lots or condominium units in a registered project may be sold. It also requires a performance bond to guarantee development obligations. (Supreme Court E-Library)

PD 957 also provides buyer protections, including:

contracts to sell and deeds of sale for subdivision lots and condominium units must be registered with the Register of Deeds;
installment payments should not be forfeited if the buyer stops paying because the developer failed to develop the project according to approved plans;
upon full payment, the developer must deliver the title;
if the buyer has taken possession, the buyer may become liable to the owner or developer for realty tax and assessment effective the year following possession and occupancy. (Supreme Court E-Library)

Today, the housing regulatory and adjudicatory structure is no longer simply “HLURB.” Republic Act No. 11201 created the Department of Human Settlements and Urban Development, transferred regulatory functions over subdivisions, condominiums, and similar real estate developments to DHSUD, and transferred the adjudicatory mandate to the Human Settlements Adjudication Commission or HSAC. (Supreme Court E-Library)

So, if the dispute involves a developer, subdivision, or condominium project, check whether the proper forum is:

DHSUD, for regulatory concerns such as license to sell, project registration, and development compliance; or
HSAC, for adjudication of certain housing and real estate disputes involving buyers, developers, homeowners associations, and similar matters.

When does the buyer’s possession become unlawful?

If the seller allowed the buyer to move in, the buyer’s possession usually starts as lawful. It becomes unlawful only when the buyer’s right to stay has expired or has been validly terminated, and the buyer refuses to leave after demand.

The Supreme Court has described unlawful detainer as a situation where possession was initially by contract or tolerance, but later became illegal after notice terminating the right of possession, followed by the occupant’s continued refusal to vacate. (Supreme Court E-Library)

For a buyer who occupies before full payment, unlawful detainer may apply when:

the buyer was allowed to occupy under the contract, move-in agreement, or seller’s tolerance;
the buyer defaulted or breached the conditions for occupancy;
the seller validly cancelled, rescinded, or terminated the buyer’s right to stay;
the seller made a clear demand to pay and/or vacate;
the buyer refused to comply.

The demand should be specific. A vague text message saying “Ayusin mo na ito” is weaker than a dated written demand stating the unpaid amounts, the breached clauses, the deadline to cure, and the demand to vacate if payment is not made.

Step-by-step: What the seller should do

1. Gather and review all documents

Collect the complete paper trail before sending demands or filing a case.

Important documents include:

Contract to Sell, Deed of Conditional Sale, Deed of Absolute Sale, or Reservation Agreement
Move-in, occupancy, or turnover agreement
payment schedule and statement of account
receipts, bank deposit slips, remittance records, and acknowledgment receipts
text messages, emails, Viber/Messenger conversations, and letters
keys turnover form, inspection form, or unit acceptance form
title, tax declaration, real property tax receipts
condominium or homeowners association records
utility bills and association dues
photos or videos showing actual occupancy and property condition

Look especially for clauses on:

retention of ownership;
default;
grace periods;
cancellation;
forfeiture;
demand requirements;
buyer’s obligation to vacate;
rentals or occupancy fees during default;
improvements introduced by the buyer;
venue and dispute resolution.

2. Determine whether ownership already transferred

Ask these practical questions:

Was a deed of absolute sale signed?
Was it notarized?
Was it delivered to the buyer?
Was the buyer placed in possession?
Was the title transferred or annotated?
Did the contract reserve ownership until full payment?
Is the buyer’s stay described as temporary occupancy only?

If ownership may already have transferred, a simple “get out” demand may not be enough. The seller may need to seek rescission, collection, damages, or other remedies.

3. Compute the buyer’s default carefully

A demand letter should not rely on rough estimates. Prepare a clear computation:

Item	What to include
Principal unpaid balance	Remaining purchase price
Past due installments	Missed installment dates and amounts
Interest	Only if allowed by contract or law
Penalties	Check if reasonable and written in the agreement
Association dues	If buyer agreed to shoulder them
Utilities	Electricity, water, internet, if unpaid
Real property tax	Especially if buyer is in actual possession
Occupancy fee or rental	Only if supported by contract or fair claim
Damage to property	Document with photos, estimates, and inspection reports

Avoid inflated claims. Excessive penalties or unsupported charges can weaken credibility and invite counterclaims.

4. Check Maceda Law before cancelling

If the buyer is paying in installments for real estate, check whether RA 6552 applies. Give the required grace period, notice, and refund if applicable. A cancellation letter that ignores Maceda Law can backfire.

For buyers who have paid substantial installments, the seller should be especially careful. The law may allow cancellation, but not arbitrary forfeiture.

5. Send a written demand

A good demand letter usually contains:

names of the parties;
property description;
contract date;
summary of payment history;
exact unpaid amount;
clause breached;
deadline to pay or cure default;
statement that failure to comply will result in cancellation, rescission, and/or demand to vacate;
demand to vacate by a specific date if the right to occupy has ended;
reservation of rights to claim damages, occupancy fees, attorney’s fees, and costs.

For immovable property, a notarial demand is often important, especially where Article 1592 or the Maceda Law is involved. A notarial act gives the demand more formal legal effect than an ordinary private letter. (Lawphil)

Service is also important. Keep proof that the buyer received the demand:

personal service with signed receiving copy;
registered mail or courier with proof of delivery;
email if allowed by the contract or acknowledged by the buyer;
barangay record, if demand was made during proceedings.

6. Do barangay conciliation if required

Many disputes between individuals must first go through Katarungang Pambarangay before a court case is filed. Supreme Court Circular No. 14-93 states that barangay conciliation is generally a pre-condition before filing a complaint in court or government offices, subject to exceptions such as disputes involving juridical entities, parties residing in different cities or municipalities, or real properties located in different cities or municipalities. (Lawphil)

For property disputes, venue is generally the barangay where the real property or the larger portion of it is located. (Supreme Court E-Library)

Barangay conciliation is commonly needed when:

seller and buyer are both natural persons;
they live in the same city or municipality, or in adjoining barangays that agree to conciliation;
no exception applies.

It is commonly not required when:

one party is a corporation, partnership, or other juridical entity;
parties reside in different cities or municipalities and the barangays are not adjoining;
urgent court relief is needed;
the case falls under an exception in the Katarungang Pambarangay rules.

If no settlement is reached, secure a Certificate to File Action. Courts can dismiss or suspend cases filed prematurely when barangay conciliation was required but skipped.

7. File unlawful detainer if the buyer refuses to leave

If possession was initially lawful but became unlawful after demand, the usual remedy is unlawful detainer, filed in the first-level court where the property is located: Metropolitan Trial Court, Municipal Trial Court in Cities, Municipal Trial Court, or Municipal Circuit Trial Court.

Unlawful detainer cases are covered by the Rules on Expedited Procedures in the First Level Courts, which took effect on April 11, 2022. The Rules cover forcible entry and unlawful detainer cases regardless of the amount of damages or unpaid rentals sought. (Supreme Court of the Philippines)

The key practical deadline is important: unlawful detainer must generally be filed within one year from the last demand to vacate. If the seller waits too long, the remedy may shift to a slower ordinary civil action, such as accion publiciana.

8. Do not forcibly remove the buyer

Even if the buyer is clearly in default, avoid:

changing locks while the buyer’s belongings are inside;
cutting off water or electricity to force the buyer out;
removing furniture or personal items;
blocking access;
using security guards to intimidate occupants;
entering the property without consent while the buyer is still in possession.

These actions can create new legal problems. Possession disputes should be handled through proper demand, barangay process where applicable, court action, and sheriff-assisted enforcement.

What buyers should know if they already moved in

A buyer who occupies before full payment should not assume that living in the property means ownership has already transferred. The buyer should check whether the agreement is a contract to sell and whether ownership is reserved until full payment.

If the buyer cannot pay on time, the buyer should:

review the contract’s grace period and default clauses;
check Maceda Law rights if paying by installment;
ask for a written restructuring agreement, not just verbal extensions;
keep proof of payments and communications;
avoid making major improvements without written consent;
pay utilities, dues, and taxes agreed to be shouldered;
avoid subleasing or letting relatives occupy unless allowed.

If the seller refuses to accept payment, the buyer may need to consider tender of payment and consignation, which means offering payment and depositing it through court in proper cases. The Supreme Court has noted consignation as a remedy where payment is refused under appropriate circumstances. (Supreme Court E-Library)

Common scenarios

The buyer paid the down payment and moved in, then stopped paying

This is the most common situation. If the contract reserves ownership until full payment, the seller should check Maceda Law, send proper demand, terminate the buyer’s right to occupy, and file unlawful detainer if the buyer refuses to leave.

The seller signed a deed of absolute sale even though the buyer still owed money

This is risky for the seller. If the deed and delivery indicate a completed sale, the seller may need to sue for the unpaid price or rescind the sale. Article 1592 may require judicial or notarial demand before rescission can cut off the buyer’s right to pay late. (Lawphil)

The buyer says, “I already spent money on renovations”

Improvements do not automatically excuse non-payment. But they can complicate settlement. The contract should say whether improvements need prior written consent and what happens to them upon cancellation. Without clear terms, buyers often claim reimbursement, while sellers argue that unauthorized improvements are at the buyer’s risk.

The buyer is a foreigner

Foreigners generally cannot own private land in the Philippines except in cases such as hereditary succession. The 1987 Constitution provides that private lands may be transferred only to individuals, corporations, or associations qualified to acquire or hold lands of the public domain, subject to the constitutional exceptions. (Lawphil)

A foreign buyer may be involved in a condominium transaction, long-term lease, or purchase through a Filipino spouse or corporation, but land ownership restrictions must be handled carefully. If the arrangement is designed to evade foreign land ownership restrictions, it can create serious enforceability problems.

The buyer is overseas or an OFW

If the buyer is abroad, service of demand becomes a practical issue. Use the address in the contract, email if recognized by prior communications or contract terms, courier to the overseas address, and service on the authorized representative if one was appointed. If documents are signed abroad, notarization may require consular acknowledgment or apostille depending on the country and intended use.

The property is in a subdivision or condominium project

Check PD 957, the license to sell, turnover documents, association dues, realty tax allocation, and whether the dispute belongs in DHSUD, HSAC, or regular court. If the issue is mainly buyer default and possession, ejectment may still be relevant; if the issue involves developer obligations, project completion, title delivery, or buyer protection, HSAC or DHSUD may be involved.

Documents and offices usually involved

Step	Documents	Office or forum	Practical timeline
Document review	Contract, title, receipts, statement of account, move-in documents	Private review	A few days to 2 weeks, depending on records
Demand	Demand letter, computation, proof of service	Notary public, courier, registered mail	Usually 1 to 2 weeks
Barangay conciliation	Complaint form, IDs, contract, demand letter	Barangay Lupon	Often 2 to 6 weeks, depending on hearings
Court filing	Verified complaint, affidavits, evidence, certification against forum shopping, Certificate to File Action if required	MTC / MeTC / MTCC / MCTC	Filing and summons may take weeks; full case length varies
Housing-related complaint	Contract, receipts, project documents, license to sell, correspondence	DHSUD or HSAC	Varies widely by region and case load
Enforcement	Final judgment, writ of execution, sheriff coordination	Court sheriff	Depends on appeal, execution schedule, and resistance

Practical drafting tips to prevent this problem

The best time to solve early occupancy problems is before turning over the keys.

A seller who allows move-in before full payment should have a written occupancy agreement stating:

the buyer is not yet the owner unless and until full payment and deed execution occur;
possession is temporary and conditional;
the buyer must pay installments, utilities, association dues, taxes, and maintenance;
default automatically suspends or terminates the right to occupy, subject to law;
the buyer must vacate after written demand;
unauthorized improvements are not reimbursable unless approved in writing;
the buyer cannot lease, assign, or allow others to occupy without consent;
the seller may inspect with reasonable notice;
occupancy fees or rentals apply during default;
all notices must be sent to stated addresses and emails.

For installment sales, the agreement should also align with RA 6552. A clause that completely forfeits all payments regardless of the buyer’s statutory rights may be void. The Maceda Law expressly declares stipulations contrary to its key protections null and void. (Lawphil)

Frequently Asked Questions

Can I evict a buyer who moved in but has not fully paid?

Yes, but usually not by force. If the buyer’s possession was initially allowed, you generally need to validly terminate the buyer’s right to occupy, make a clear demand to vacate, comply with Maceda Law if applicable, go through barangay conciliation if required, and file unlawful detainer if the buyer refuses to leave.

Does possession mean the buyer already owns the property?

Not always. Under the Civil Code, delivery can transfer ownership in a sale, but the parties may also agree that ownership stays with the seller until full payment. This is why a contract to sell is commonly used when the buyer pays in installments. (Lawphil)

What if the buyer paid a large down payment?

A large down payment does not automatically transfer ownership. But it may trigger protections under the contract, the Maceda Law, or equitable considerations. If the buyer has paid at least two years of installments, RA 6552 gives specific grace period and refund rights. (Lawphil)

Can the seller keep all payments if the buyer defaults?

Not always. For installment real estate sales covered by the Maceda Law, the buyer may be entitled to statutory grace periods and, in some cases, cash surrender value. For subdivision and condominium projects, PD 957 also restricts forfeiture in certain developer-default situations. (Lawphil)

Do I need a notarized demand letter?

Often, yes. For sales of immovable property, Article 1592 recognizes demand for rescission by judicial or notarial act. The Maceda Law also refers to notice of cancellation or demand for rescission by notarial act. A notarized demand is usually stronger than an ordinary email or text message. (Lawphil)

Should I file in barangay first?

If both parties are individuals and the dispute falls within the Katarungang Pambarangay rules, barangay conciliation may be required before court filing. If one party is a corporation or the parties reside in different cities or municipalities, an exception may apply. (Lawphil)

What court handles a buyer who refuses to vacate?

Usually, unlawful detainer is filed in the first-level court where the property is located. These cases are covered by the Rules on Expedited Procedures in the First Level Courts. (Supreme Court of the Philippines)

Can I cut off utilities if the buyer refuses to pay?

This is risky. Even when the buyer is in default, forcing the buyer out by cutting utilities, padlocking, or blocking access can create separate civil or criminal complaints. Use written demand, barangay proceedings where required, court action, and sheriff-assisted enforcement.

What if the buyer is a foreigner?

Foreigners generally cannot own private land in the Philippines except in limited constitutional situations such as hereditary succession. They may be involved in condominium ownership or lease arrangements, but land transactions with foreigners require careful review because invalid structures can affect enforceability. (Lawphil)

What if there is no written contract?

The case becomes more evidence-heavy. Receipts, messages, bank transfers, witnesses, possession, tax payments, and conduct of the parties become important. But for real estate, relying on verbal arrangements is dangerous. A written, notarized agreement is far safer, especially where possession is given before full payment.
