Buying a condo unit from a seller who has not yet fully paid the developer can be legitimate in the Philippines, but it is not a normal “resale” yet. In most cases, the seller does not yet have a Condominium Certificate of Title (CCT) in their name. What they usually have is a buyer’s right under a Contract to Sell with the developer. That means you are not simply buying a titled condo from an owner; you are usually taking over the seller’s rights, payments, penalties, and obligations — and you normally need the developer’s written approval before the transaction becomes safe.

Why This Kind of Condo Purchase Is Risky

The biggest risk is simple: the seller may not yet own the condo in the way buyers usually understand ownership.

In Philippine condominium projects, especially preselling or installment units, the first buyer usually signs a Contract to Sell with the developer. A Contract to Sell is different from a Deed of Absolute Sale. In a Contract to Sell, the developer generally keeps ownership until the buyer fully pays the price and complies with all requirements. The Supreme Court has repeatedly recognized that, in a contract to sell, title is retained by the seller until full payment of the purchase price. (Lawphil)

So if the original buyer has not fully paid the developer, that buyer may only have a contractual right to acquire the unit later, not full registered ownership today.

That does not automatically make the transaction illegal. It means the transaction must be handled as an assignment of rights, transfer of account, or assumption of balance, not as a simple sale of a titled condo.

The Legal Concept: Sale of a Condo vs. Assignment of Rights

A normal sale of a titled condo usually involves:

a Condominium Certificate of Title in the seller’s name;
a Deed of Absolute Sale;
payment of BIR taxes;
issuance of a Certificate Authorizing Registration or eCAR;
payment of local transfer tax;
registration with the Registry of Deeds; and
issuance of a new CCT in the buyer’s name.

But when the seller has not fully paid the developer, the usual situation is different.

The seller may have:

a Reservation Agreement;
a Contract to Sell;
official receipts;
a statement of account;
a payment schedule;
a turnover notice;
a loan approval or in-house financing arrangement;
unpaid amortizations, penalties, association dues, or transfer charges; and
no CCT yet in the seller’s name.

Under Article 1458 of the Civil Code, a contract of sale involves an obligation to transfer ownership and deliver a determinate thing for a price. Article 1459 adds that the vendor must have the right to transfer ownership at the time the property is delivered. (Lawphil)

That is why, in practice, the safer structure is usually not “I sell you my condo.” It is closer to:

“I assign to you my rights and obligations under my Contract to Sell with the developer, subject to the developer’s approval, full settlement of account requirements, and execution of the developer’s transfer documents.”

What the Seller Can and Cannot Transfer

A seller who has not fully paid the developer can usually transfer only what they actually have.

Seller’s Status	What Seller Usually Has	Safer Transaction Type	Main Risk
Unit is preselling and under Contract to Sell	Right to continue buying the unit	Assignment of rights / transfer of account	Developer may reject the transfer
Unit is turned over but not fully paid	Possession plus contractual rights	Assignment with assumption of balance	Arrears, penalties, unpaid dues
Unit is fully paid but title not yet released	Stronger right to demand title/deed	Sale or assignment depending on documents	Delay in CCT release
CCT already in seller’s name	Registered ownership	Deed of Absolute Sale	Normal title-transfer risks
Unit is mortgaged to a bank	Ownership subject to mortgage	Sale with loan takeout or mortgage release	Bank consent and release needed

The practical rule is: do not pay as if you are buying clean title unless clean title actually exists.

Key Philippine Laws That Matter

Civil Code: ownership, delivery, and authority to sell

The Civil Code provisions on sales matter because a buyer must know whether the seller can actually transfer ownership.

Under Article 1475, a sale is perfected when the parties agree on the object and price. But perfection of a contract is not the same as transfer of registered ownership. For immovable property, ownership and real rights are generally transferred through delivery or tradition, and in real estate practice, registration with the Registry of Deeds is crucial for protection against third persons. (Lawphil)

Article 1544 of the Civil Code is also important in double-sale situations. For immovable property, the buyer who first registers in good faith generally has the stronger claim. The Supreme Court has emphasized that registration must be coupled with good faith. (Lawphil)

RA 4726: The Condominium Act

Republic Act No. 4726, or the Condominium Act, defines a condominium as an interest in real property consisting of a separate interest in a unit and an undivided interest in the common areas or land, directly or indirectly. (Lawphil)

For foreigners, this law is especially important because foreign ownership in a condominium project is generally allowed only up to the constitutional and statutory limit, commonly applied as the 40% foreign ownership cap in the condominium corporation. The Supreme Court has recognized that the Condominium Act allows foreigners to acquire condominium units and shares in condominium corporations up to not more than 40% of the total and outstanding capital stock. (Lawphil)

PD 957: protection for subdivision and condominium buyers

Presidential Decree No. 957 regulates the sale of subdivision lots and condominium units and was enacted to protect buyers against abuses such as failure to deliver titles, fraudulent sales, and failure to complete promised project features. (Lawphil)

For projects covered by PD 957, the developer should have proper registration and a License to Sell before selling condominium units. DHSUD explains that a License to Sell is issued only for subdivision and condominium projects with approved plans complying with required minimum standards. (DHSUD)

PD 957 also matters because DHSUD states that the developer must deliver the title of the subdivision lot or condominium unit to the buyer upon full payment. (DHSUD)

RA 6552: Maceda Law protection for installment buyers

Republic Act No. 6552, known as the Realty Installment Buyer Act or Maceda Law, protects buyers of real estate on installment payments against oppressive conditions. (Lawphil)

This is relevant because the original seller may have refund or grace-period rights if they default. But as the new buyer, you should not assume you automatically inherit those protections unless the transfer is properly documented and recognized by the developer.

The Supreme Court has emphasized that cancellation under RA 6552 generally requires compliance with mandatory requirements, including a notarized notice of cancellation and, where applicable, refund of the cash surrender value. (Supreme Court E-Library)

RA 11201: DHSUD and HSAC

Republic Act No. 11201 created the Department of Human Settlements and Urban Development (DHSUD) and transferred the former HLURB’s regulatory functions to DHSUD. It also created the Human Settlements Adjudication Commission (HSAC) for adjudicatory functions. (Supreme Court E-Library)

For buyers, this matters because disputes involving developers, condominium projects, non-delivery, cancellation, and buyer protection issues may fall within the housing and real estate regulatory/adjudicatory system rather than ordinary collection-style negotiation alone.

The Safest Way to Buy: Step-by-Step Due Diligence

1. Ask what document the seller actually has

Before discussing price, ask for copies of:

Reservation Agreement;
Contract to Sell;
official receipts;
statement of account from the developer;
payment schedule;
turnover documents, if any;
parking slot documents, if included;
notices of default or penalty notices;
written developer policy on transfers or assignments; and
seller’s valid IDs and civil status documents.

The most important question is:

Is the unit already titled in the seller’s name, or is it still under the developer’s account?

If there is no CCT in the seller’s name, treat the transaction as a transfer of rights, not an ordinary sale.

2. Verify the project with DHSUD

For a preselling or developer-controlled unit, check whether the project has a proper Certificate of Registration and License to Sell. DHSUD’s buyer guidance specifically encourages buyers to check whether the landowner or developer is the one actually selling the condominium unit and whether the project is properly authorized. (DHSUD)

For older projects, also ask whether the condominium corporation has already been turned over, whether the master deed is registered, and whether the project has issues with title release.

3. Request a fresh statement of account directly from the developer

Do not rely only on screenshots, old receipts, or the seller’s spreadsheet.

Ask the developer for a current account statement showing:

total contract price;
total payments made;
remaining balance;
unpaid amortizations;
penalties and interest;
transfer fee or assignment fee;
documentation fee;
turnover charges;
real property tax advances, if any;
condominium dues, if already turned over;
parking dues, if applicable; and
exact amount needed to update or fully settle the account.

This is where many buyers discover that the “discounted” unit is not really discounted after arrears and penalties are added.

4. Get the developer’s written consent before paying the seller in full

Many developer contracts prohibit assignment or transfer without the developer’s prior written consent. Some developers allow transfer only after a minimum percentage has been paid. Others require the account to be updated first. Some impose transfer fees. Some reject transfers if the buyer is a foreigner and the foreign quota is already full.

The buyer should not pay the full purchase price to the seller until the developer confirms in writing that:

the seller’s account can be transferred;
the buyer is qualified;
the required transfer documents are acceptable;
the exact balance and charges are confirmed;
the developer will recognize the buyer as the new account holder after completion; and
the developer will issue an amended Contract to Sell, Deed of Assignment, or other official transfer document.

5. Structure payments safely

A risky structure looks like this:

buyer pays the seller directly;
seller promises to update the account;
seller promises to process the transfer later;
buyer later discovers developer consent was not obtained.

A safer structure is:

buyer, seller, and developer confirm the account status;
buyer pays arrears or balance directly to the developer, if allowed;
seller receives only the agreed “equity” or premium after transfer approval;
documents are signed and notarized;
developer issues written acknowledgment of the buyer as transferee; and
original receipts and account records are turned over.

For large amounts, parties sometimes use escrow arrangements, manager’s checks with conditional release, or simultaneous signing at the developer’s office. The key is to avoid a situation where the seller has your money but the developer still does not recognize you.

6. Check the seller’s authority and civil status

If the seller is married, do not ignore spousal consent.

Under the Family Code, administration and enjoyment of community or conjugal property generally belong to both spouses jointly. The Supreme Court has repeatedly dealt with cases involving sales or dispositions of conjugal property without proper spousal consent, and such defects can create serious title or validity issues. (Lawphil)

If the seller is abroad, the person signing in the Philippines must have a proper Special Power of Attorney. Under Article 1878 of the Civil Code, a Special Power of Attorney is required for acts involving the sale or transfer of real rights over immovable property, and the Supreme Court has applied this requirement strictly. (Lawphil)

For overseas Filipinos and foreigners signing documents abroad, Philippine consulates can notarize documents for use in the Philippines, including powers of attorney and deeds, and personal appearance is typically required for consular notarization. (Philippine Consulate LA)

7. Check if the unit is already mortgaged or assigned to a bank

Some buyers assume the unpaid balance is only with the developer. But the seller may have already financed the unit through:

bank loan;
Pag-IBIG financing;
in-house financing;
deferred cash arrangement;
post-dated checks;
promissory notes; or
a mortgage after title release.

If a bank loan is involved, you normally need the bank’s consent, a loan takeout arrangement, or full settlement and release of mortgage. Do not accept informal promises that the seller will “continue paying the bank” while you occupy the unit.

8. Confirm tax consequences before signing

If the transaction is a true sale of titled property, BIR taxes and title transfer requirements usually apply. For capital assets, BIR Form 1706 guidance states that the 6% capital gains tax is based on the selling price, zonal value, or fair market value per tax declaration, whichever is higher. (Bir Cdn)

Documentary Stamp Tax on real property transfers is also a major cost, and BIR guidance provides that the DST return is generally filed within five days after the close of the month when the taxable document was made, signed, accepted, or transferred. (Bureau of Internal Revenue)

For title registration, the BIR issues an electronic Certificate Authorizing Registration or eCAR, which allows the Land Registration Authority and Registry of Deeds to process the transfer. (Bureau of Internal Revenue Web Services)

For an assignment of rights before title issuance, tax treatment can be more fact-specific. Some transactions may involve assignment documents, developer transfer fees, and BIR review depending on the structure and stage of the account. It is risky to sign a document labeled “Deed of Sale” if the seller does not yet have title and the developer has not approved the transfer.

Documents to Request Before Paying

Document	Why It Matters
Seller’s Contract to Sell	Shows whether assignment is allowed and what conditions apply
Latest statement of account	Confirms balance, arrears, penalties, and charges
Official receipts	Proves payments actually made
Developer transfer policy	Shows fees, consent requirements, and restrictions
Written developer approval	Confirms the transfer can proceed
Draft Deed of Assignment / Transfer of Rights	Main document if seller has no title yet
Seller’s IDs and TIN	Needed for documentation and tax processing
Marriage certificate or proof of civil status	Determines need for spousal consent
SPA, if seller is represented	Confirms authority of representative
CCT, if already issued	Confirms registered ownership
Tax declaration and real property tax clearance, if applicable	Used in later tax/title work
Condo dues clearance	Prevents hidden association liabilities
Foreign quota certification, if buyer is foreign	Confirms the buyer can validly acquire the unit

Common Red Flags

Be extra careful if you see any of these:

seller refuses to let you verify directly with the developer;
seller says “no need to tell the developer”;
seller wants full payment before transfer approval;
seller cannot produce official receipts;
account has many missed amortizations;
developer says the account is already for cancellation;
seller is abroad but representative has only a general authorization;
spouse refuses to sign;
unit includes parking but parking slot documents are unclear;
seller is offering a very large discount but cannot explain the account history;
buyer is foreign and no one has checked the project’s foreign ownership cap;
document is titled “Deed of Absolute Sale” even though the seller has no CCT;
developer will not issue a written acknowledgment of the transferee.

The phrase “assume balance” should always trigger deeper review. It can be a good deal, but only if the balance, arrears, rights, and approvals are all clear.

Practical Scenarios

Scenario 1: Preselling unit, seller paid only 30%

This is usually an assignment-of-rights transaction. The buyer should verify whether the developer allows transfer at that stage. Some developers require a minimum payment threshold or account update before approving assignment.

Scenario 2: Unit already turned over, but still under in-house financing

This can be riskier because possession may already have been given, but ownership is still not transferred. Check unpaid dues, real property tax advances, move-in fees, and whether the seller has default notices.

Scenario 3: Seller is fully paid, but CCT is delayed

This may be safer than a low-equity transfer, but still requires verification. Ask why the CCT is delayed. Common reasons include pending master title work, BIR processing, developer backlog, unpaid closing fees, incomplete buyer documents, or project registration issues.

Scenario 4: Foreigner buying from a Filipino original buyer

A foreign buyer must check whether the condominium project still has available foreign ownership capacity. Even if the seller is Filipino, the transfer to a foreign buyer may be blocked if the project has already reached the foreign ownership limit recognized under the Condominium Act framework. (Lawphil)

Scenario 5: Seller’s account is already in default

If the account is already subject to cancellation, the buyer should not rely on verbal assurances. RA 6552 may give the original buyer certain protections, but the buyer stepping in should require a written reinstatement or updated approval from the developer before paying substantial money.

Typical Timeline

Step	Usual Timeline	Common Bottleneck
Request documents from seller	1–7 days	Seller has incomplete records
Developer account verification	3–15 working days	Developer needs authorization from seller
Transfer approval review	1–4 weeks	Arrears, foreign quota, missing IDs
Signing and notarization	1–7 days	Seller or spouse is abroad
Developer recognition of transferee	1–4 weeks	Internal approval and payment posting
Full title transfer after complete payment	Several weeks to several months	BIR eCAR, Registry of Deeds, developer backlog

For OFWs and foreign-based sellers, add time for consular notarization, courier delivery, or apostille/authentication issues.

How to Reduce the Risk

A buyer can reduce risk by following these rules:

Verify with the developer before paying. The developer’s records are more important than the seller’s screenshots.
Use the correct document. If there is no CCT yet, the document is usually a Deed of Assignment or transfer-of-rights document, not a simple Deed of Absolute Sale.
Pay arrears directly to the developer when possible. This prevents the seller from receiving money meant to cure default.
Require written developer approval. Verbal approval from an agent or broker is not enough.
Check all hidden costs. Include penalties, transfer fees, closing fees, VAT issues, dues, taxes, and documentation charges.
Do not ignore spousal consent or SPA defects. A defective signature can cause serious problems later.
For foreigners, check the foreign quota early. Do this before spending on due diligence or paying reservation money.
Keep proof of every payment. Use bank transfers, manager’s checks, receipts, and written acknowledgments.
Do not move in based only on trust. Possession without recognized rights can lead to conflict if the account is later cancelled.
Make the seller’s payment conditional. The seller’s equity or premium should be released only after the developer approves the transfer.

Frequently Asked Questions

Is it legal to buy a condo from someone who has not fully paid the developer?

Yes, it can be legal, but it should usually be treated as an assignment of rights or transfer of account, not a regular sale of a titled condo. The developer’s written consent is normally essential.

Can the seller issue a Deed of Absolute Sale if the condo is not fully paid?

Usually, that is risky. If the seller has no CCT and the developer still owns the unit under a Contract to Sell, the seller may not be able to transfer registered ownership. A Deed of Assignment or developer-approved transfer document is usually more appropriate.

What is an assignment of rights in a condo purchase?

An assignment of rights is a document where the original buyer transfers their rights and obligations under the Contract to Sell to a new buyer. In condo projects, this usually needs developer approval because the developer must recognize the new buyer as the account holder.

Should I pay the seller’s equity directly to the seller?

Not immediately. First confirm the account with the developer. If there are arrears, penalties, or transfer fees, consider paying those directly to the developer and releasing the seller’s equity only after written transfer approval.

What happens if the seller stops paying the developer after I pay the seller?

If the developer does not recognize you as the transferee, the account may still be under the seller’s name. The developer may treat the seller as the defaulting buyer, and you may have to chase the seller to recover your money. This is one of the main reasons developer-approved documentation is critical.

Can the developer refuse the transfer?

Yes. The developer may refuse if the Contract to Sell prohibits transfer, the account is in default, required fees are unpaid, documents are incomplete, the buyer is not qualified, or the foreign ownership cap is already full.

What if the seller already turned over the unit to me?

Physical possession does not automatically mean ownership. If the developer has not approved the transfer and the account remains unpaid or in default, possession can become a serious problem. Always align possession with written legal recognition.

Does Maceda Law protect me as the new buyer?

RA 6552 protects real estate installment buyers, but if you are taking over someone else’s account, your protection depends heavily on whether the assignment is validly documented and recognized by the developer. Do not assume you have Maceda Law rights unless the developer has officially accepted you as buyer or transferee.

Can a foreigner assume balance on a Philippine condo?

A foreigner may buy or assume rights to a condominium unit only if the transaction complies with the Condominium Act and the project’s foreign ownership limit. The buyer should obtain confirmation from the developer or condominium corporation before signing.

Who handles disputes if the developer refuses to recognize the transfer?

If the dispute involves a condominium project, buyer rights, cancellation, delivery, title issuance, or developer obligations, DHSUD or HSAC may be relevant depending on whether the matter is regulatory or adjudicatory. DHSUD states that buyers may seek assistance from its Regional Office or file a formal complaint when developers fail to fulfill obligations. (DHSUD)

Key Takeaways

Buying from a seller who has not fully paid the developer is risky but manageable if structured correctly.
The seller may not yet own the condo; they may only have rights under a Contract to Sell.
The safest route is usually a developer-approved assignment of rights or transfer of account.
Do not pay the seller in full before verifying the account, balance, arrears, penalties, and transfer requirements.
Require written developer consent, proper notarized documents, spousal consent when needed, and a valid SPA if someone signs for a party abroad.
Foreign buyers must check the condominium project’s foreign ownership capacity before committing.
A low price is not a good deal if the account is in default, the developer rejects the transfer, or title cannot later be issued.
