I. Why this issue matters

In the Philippines, it’s common for a buyer to be allowed to take possession of a house, lot, or condo unit before the Transfer Certificate of Title (TCT)/Condominium Certificate of Title (CCT) is transferred to the buyer—especially in installment purchases under a Contract to Sell (CTS). The practical temptation is to start improving the property early (fit-outs, partitions, extensions, flooring, roofing, fencing).

Legally, that is a high-risk move unless the contract is carefully drafted, because in a CTS the seller usually remains the owner until conditions are fulfilled (typically full payment). Improvements may “stick” to the property through accession, but that does not automatically mean the buyer will be reimbursed if the deal collapses.

This article explains the Philippine legal framework, the risks, and the concrete legal options and protections for both buyer and seller.

II. Contract to Sell vs Contract of Sale: the core distinction

A. Contract of Sale (CoS)

A Contract of Sale generally means there is a meeting of minds to transfer ownership for a price, and ownership may pass upon delivery (actual or constructive), unless the contract provides otherwise.

B. Contract to Sell (CTS)

A Contract to Sell is typically a conditional sale where:

The seller reserves ownership; and
The seller’s obligation to execute a Deed of Absolute Sale and transfer title arises only upon full payment (or satisfaction of conditions).

Key consequence: Even if the buyer is already living in or using the property, the buyer is often not yet the owner—the buyer’s right is usually personal (contractual), not a real right in rem, unless properly protected/registered in some form.

III. Renovations before title transfer: what “law” is triggered

When a buyer renovates property they don’t yet own, several bodies of law can apply:

Civil Code on ownership and accession Improvements attached to land/buildings are generally treated as part of the property (accession). The law then looks at who built and in what faith.
Civil Code on possessors and improvements If the buyer is a possessor (with or without right), rules on reimbursement and retention may apply depending on good faith vs bad faith.
Civil Code on builders/planters/sowers If the buyer is treated as a builder in good faith, there may be reimbursement/indemnity consequences.
Maceda Law (RA 6552) (if applicable) Protects buyers of residential real estate on installment payments, granting rights like grace periods and cash surrender value—important when a CTS is cancelled and improvements are involved.
Developer laws and regulations (if applicable) For subdivision/condo developer transactions, rules on buyer protection and project obligations may affect remedies and forums.
Property registration principles (PD 1529) Registration/annotation issues shape third-party enforceability and priority.
Local permitting laws and condo/subdivision restrictions Renovations may be illegal or removable if done without permits/HOA/condo approvals.

IV. The biggest legal risks for the buyer

1) You may lose the improvements (or get only partial recovery)

Even if you funded the renovation, once it is attached, it typically becomes part of the property. If the contract is cancelled and you leave, the seller keeps the improved property unless you have enforceable rights to reimbursement or removal.

2) Your right may be treated as purely contractual

Without a strong contract clause (and sometimes without registration/annotation), you may only have a claim for damages—which can be slow, disputed, or hard to collect.

3) Renovations may violate law or project rules

Building permits typically require authority from the owner (or an authorized representative).
In condominiums, alterations often require condo corp approval and compliance with the master deed/house rules. Unpermitted renovations can expose you to:
Stop-work orders,
Demolition,
Liability for damages to common areas/other units.

4) Default changes the “good faith” analysis

A buyer who is initially in good faith can be deemed to have lost good faith once notified of a defect in right (e.g., valid cancellation, demand to vacate, notice of breach). This can reduce reimbursement rights.

5) Third-party issues (mortgages, prior sales, liens)

If the seller’s title has encumbrances (mortgage, adverse claims, prior sale), your improvements can end up benefiting someone else, and your remedies may be limited to suing the seller.

V. When buyer renovations can be legally protected: key concepts

A. “Possessor in good faith” and reimbursement

Under the Civil Code framework, a possessor in good faith is generally entitled to reimbursement for:

Necessary expenses (to preserve the property), and
Often useful expenses (those that increase value), and may have a right of retention until reimbursed (subject to procedural realities and the nature of the case).

A CTS buyer who occupies with the seller’s consent can often argue they are a possessor in good faith at least until a valid notice of cancellation/breach is served.

B. Builder in good faith doctrines

Where someone builds or introduces improvements believing they have a right to do so, the law provides equitable consequences—often pushing toward:

indemnification/reimbursement, or
forced sale options in some fact patterns, but outcomes depend heavily on whether the builder is truly in good faith and what exactly was built (new structure vs alterations).

C. Unjust enrichment

Even where strict property rules are unfavorable, a buyer may invoke the principle that no one should unjustly enrich themselves at another’s expense. This is often pleaded alongside contractual and Civil Code claims, especially when:

Seller encouraged renovations,
Seller approved plans,
Seller benefited directly upon cancellation.

VI. The contract is king: what the CTS should say (and what buyers should insist on)

If you renovate before title transfer, the CTS must be explicit. The best protections are contractual.

A. Written authority to renovate

Include a clause that:

Seller authorizes specific renovations (scope-based),
Buyer may obtain permits using an SPA (Special Power of Attorney),
Renovation must comply with laws/HOA/condo rules.

B. Ownership of improvements and reimbursement formula

A strong clause answers:

Who owns improvements before full payment?
If the CTS is cancelled (by buyer default or seller breach), what happens?

Common approaches:

Reimbursement approach: seller must reimburse verified costs (or appraised value increase), less wear and tear.
Removal approach: buyer may remove certain improvements if separable and without damage (rarely practical).
Liquidated valuation: pre-agreed schedule (e.g., 80% of documented costs if cancelled within year 1; 60% within year 2, etc.).
Set-off approach: improvement value is offset against unpaid balance or penalties.

C. Evidence and audit mechanics

Require:

Pre-approval of plans,
Itemized receipts,
Before/after photos,
Joint inspection and sign-off,
Optional third-party appraisal.

D. Retention/possession protections

If cancellation occurs:

Provide a cure period beyond statutory minimums (if applicable),
Provide a move-out timeline tied to reimbursement payment,
Provide escrow mechanics to avoid one side holding all leverage.

E. Escrow/Security devices

For buyer protection:

Seller deposits post-dated deed or signed deed in escrow released upon full payment.
Seller provides performance bond (rare in consumer deals but strong). For seller protection:
Buyer posts a renovation bond for damage, contractor liens, common area repairs.

F. Registration/annotation strategy (case-by-case)

Because a CTS buyer is vulnerable to third parties, discuss with counsel whether to:

Register/annotate the CTS or a memorandum,
File an adverse claim (in appropriate situations),
Use notice of lis pendens if litigation is filed, so third parties are warned of your claim. (These are technical and must be used carefully to avoid wrongful annotation exposure.)

VII. What legal remedies does the buyer have if things go wrong?

Your options depend on why the deal collapsed and what the CTS says.

Scenario 1: Seller refuses to transfer title despite buyer’s compliance

Primary remedies:

Demand for specific performance (compel execution of deed and transfer of title)
Damages (actual, moral/exemplary in proper cases, attorney’s fees if justified/contracted)
Consignation of payment if seller refuses to accept payment (to show buyer is not in default)

Why renovations matter here: Renovations support damages and equities (seller benefited; buyer relied), and may justify provisional remedies.

Scenario 2: Seller cancels the CTS alleging buyer default; buyer disputes cancellation

Buyer’s remedies:

Challenge the validity of cancellation (notice requirements, grace periods, computation disputes)
If covered, invoke RA 6552 (Maceda Law) protections for residential installment buyers:
- Grace periods
- Cash surrender value after a threshold
- Proper cancellation procedures

Renovation recovery: You plead reimbursement for useful/necessary expenses, unjust enrichment, and contract-based reimbursement if any.

Scenario 3: Buyer truly defaulted and cancellation is valid

This is the hardest case for the buyer. Still possible claims:

Cash surrender value (if Maceda Law applies and requirements are met)
Reimbursement for necessary expenses (more likely than useful expenses if good faith is lost)
Equitable reimbursement if seller explicitly induced renovations

But practically, outcomes often depend on documentation and the exact contract clauses.

Scenario 4: Seller is not the real owner / property is encumbered / double sale issues

Buyer may sue for:

Annulment/rescission plus damages
Return of payments
Damages for improvements under unjust enrichment and bad faith theories If a third party with better title prevails, the buyer’s remedies may primarily be against the seller, not against the property.

VIII. Procedural and forum options in the Philippines

Where to file depends on the nature of the transaction and defendant:

Regular courts (RTC/MTC)
- Specific performance, rescission, damages, title-related actions
- Ejectment (unlawful detainer/forcible entry) is typically in MTC, but is limited in scope.
Developer-related disputes If the seller is a subdivision/condo developer and the dispute relates to project sales and obligations, the specialized housing forum and regulatory framework may apply (often faster and more technical).
Alternative dispute resolution Many CTS contracts require mediation/arbitration. Even without a clause, settlement is common because improvement valuation is fact-heavy and litigation is slow.

IX. Practical “legal hygiene” for buyers who still want to renovate early

If you must renovate before title transfer, do these to avoid losing everything:

A. Get a written, specific renovation authority

Not just “buyer may improve,” but scope, standards, approvals, and consequences.

B. Secure permits properly

If permits must be in the owner’s name, require seller cooperation and an SPA.

C. Document everything like you’re preparing for court

Receipts, contracts, progress billing, delivery receipts, photos, and inspection reports.

D. Use staged renovations tied to payment milestones

Avoid heavy structural works until you’re near full payment.

E. Demand an improvement reimbursement clause with a clear formula

Leave as little as possible to “equity” or “we’ll talk later.”

F. Check title and encumbrances first

Verify the seller’s title status, liens, mortgages, and authority to sell.

G. Condo/HOA compliance

Get approvals in writing; comply with work hours, contractor accreditation, deposit requirements.

X. Seller-side perspective: how sellers should manage buyer renovations

Sellers also face risk: unsafe works, unpaid contractors, damage to structure, neighbor claims, and messy turnover.

Seller protections commonly include:

Prior written approval of plans
Proof of contractor licensing/insurance
Renovation bond and common area deposits (condos)
Indemnity clauses and restoration obligations if cancellation occurs
Strict prohibition on structural changes prior to full payment

XI. Common clauses (conceptual templates)

Below are clause concepts (not plug-and-play language):

Renovation Permission Clause “Seller authorizes Buyer to perform the following renovations… subject to written approval… compliance with law… permits…”
Reimbursement Upon Cancellation Clause “If this CTS is cancelled for any reason other than Buyer’s fraud/willful breach, Seller shall reimburse documented useful improvements at __% of verified costs or appraised incremental value, whichever is lower, payable within __ days…”
Set-Off Clause “Any reimbursable improvements shall be offset against amounts due, penalties, or surrender value…”
Inspection and Valuation Clause “Parties shall jointly inspect and sign a completion certificate; in case of dispute, an independent appraiser’s valuation shall govern…”
Possession/Move-Out Clause “Buyer shall vacate within __ days after reimbursement is paid / escrow released…”
Escrow Clause “Reimbursement funds shall be deposited in escrow; Buyer releases possession upon confirmation of deposit…”

XII. Bottom line guidance

Under a Contract to Sell, the buyer who renovates early is often improving someone else’s property until full payment triggers transfer of title.
The buyer’s best protection is contract drafting: explicit authorization, valuation, reimbursement or set-off mechanics, and evidence requirements.
If the deal breaks down, the buyer may rely on contract rights, possessor/builder reimbursement principles, and unjust enrichment, plus statutory protections like RA 6552 when applicable—but outcomes become uncertain and fact-intensive without strong documentation and clauses.

Or a litigation demand letter outline for reimbursement/specific performance.
