In the Philippines, vast tracts of land—particularly in rural and provincial areas—remain untitled and are evidenced solely by a Tax Declaration (TD) issued by the local assessor’s office and a notarized Deed of Sale (or other unregistered instrument) showing acquisition from a prior holder. These documents do not constitute a Torrens title under Presidential Decree No. 1529 but are sufficient to establish presumptive ownership and possession for purposes of taxation and transfer between private parties. Selling only a portion of such land adds layers of technical, documentary, and fiscal requirements because the transaction involves subdivision, precise identification of boundaries, and transfer of tax records without the benefit of a certificate of title.

Legal Framework Governing the Transaction

The Civil Code of the Philippines (Republic Act No. 386) governs contracts of sale of immovable property. Article 1458 defines sale as the delivery of a thing in exchange for a price; Article 1475 states that the contract is perfected by mere consent; and Article 1495 requires the seller to transfer ownership. Ownership over untitled land may be acquired through acquisitive prescription (ordinary or extraordinary) or by open, continuous, exclusive, and notorious possession under a claim of ownership for the periods prescribed in Articles 1134 to 1137. A Tax Declaration in the seller’s name, coupled with actual possession and payment of real property taxes, serves as strong corroborative evidence of such ownership (consistent with long-standing jurisprudence treating tax declarations as indicia of possession though not of title).

Because the land lacks a Torrens title, the transaction is not registered with the Register of Deeds. Instead, transfer occurs through (a) execution of a public instrument (notarized Deed of Absolute Sale), (b) payment of required national and local taxes, and (c) cancellation and issuance of new Tax Declarations by the provincial or city assessor. The sale is valid and binding between the parties and their successors, though it remains vulnerable to third-party claims until the buyer perfects title through judicial or administrative proceedings.

Ownership Evidence: The Limited Role of Tax Declaration and Prior Deed of Sale

A Tax Declaration is a public document issued by the local assessor showing the declared owner, area, boundaries, assessed value, and tax payments. It is prima facie evidence of possession and tax liability but does not prove ownership against the State or adverse claimants. The prior Deed of Sale in the seller’s favor merely documents the previous transfer; it must be presented to prove the chain of acquisition. For the current seller to convey valid title, the following must concur:

The seller must appear as the declared owner in the latest Tax Declaration.
Real property taxes must be fully paid up to the date of sale.
There must be no unreleased liens, adverse claims, or notices of lis pendens annotated on the Tax Declaration or known to the parties.
The seller must have been in actual, peaceful possession of the entire land (or at least the portion being sold) for the prescriptive period if relying on prescription.

If the seller is married and the land was acquired during the marriage, the property is presumed conjugal; the spouse’s written consent is mandatory under the Family Code to avoid nullity of the sale.

Specific Requirements When Selling Only a Portion

Selling a portion of untitled land requires physical and technical segregation before the sale can be consummated. The law and administrative practice demand:

Subdivision Survey Plan
A licensed geodetic engineer must prepare a subdivision plan (or “sketch plan” for small areas) showing the metes and bounds of the portion being sold and the remaining area. The plan must include technical descriptions, bearings, distances, and tie points to an established reference. For untitled lands, this plan is submitted to the Land Management Bureau (LMB) or the DENR Regional Office for verification and approval. The approved plan becomes an integral part of the new Deed of Absolute Sale and the basis for issuing separate Tax Declarations.
Clear Identification of the Portion
The Deed of Absolute Sale must contain an exact technical description copied from the approved subdivision plan. A mere verbal or rough sketch description is legally insufficient and may render the sale voidable for lack of determinate object.
No Adverse Claims or Overlaps
The seller must execute an Affidavit of Non-Encumbrance and Non-Tenancy (if agricultural). The buyer should verify with the local assessor’s office, the barangay, and adjacent owners that no overlapping declarations or pending claims exist.
Compliance with Land Use and Agrarian Laws
If the land is agricultural and the portion exceeds five hectares or forms part of an area covered by the Comprehensive Agrarian Reform Program (Republic Act No. 6657), a Department of Agrarian Reform (DAR) clearance may be required. For lands within urban zones or subdivisions, local zoning clearance from the city or municipal planning office may be needed.

Documentary Requirements for the Transaction

The complete set of documents typically required includes:

Original and certified true copies of the seller’s current Tax Declaration covering the entire land.
Original prior Deed of Sale or other muniment of title in the seller’s name.
Approved subdivision plan (LMB-verified) with technical description.
Notarized Deed of Absolute Sale executed by the seller (and spouse, if applicable), containing the full technical description of the portion, purchase price, and warranties of ownership and peaceful possession.
Proof of payment of all real property taxes up to the year of sale.
Seller’s valid government-issued identification and, if applicable, Community Tax Certificate (cedula).
Buyer’s proof of identity.
Affidavit of non-encumbrance, non-tenancy, and true consideration (to avoid under-declaration for tax purposes).

Step-by-Step Procedure

Due Diligence and Preparation
Buyer and seller verify possession, tax payments, and absence of claims. A geodetic engineer is engaged to conduct the subdivision survey.
Approval of Subdivision Plan
The plan is submitted to the LMB or DENR-Land Management Services for approval (usually 15–30 working days).
Execution and Notarization
The Deed of Absolute Sale is signed before a notary public. The notary retains one copy and issues certified copies.
Payment of National Taxes
The seller computes and pays Capital Gains Tax (6% of the higher of gross selling price or zonal value/fair market value per BIR) and Documentary Stamp Tax (1.5% of the same base) with the Bureau of Internal Revenue. The BIR issues a Certificate Authorizing Registration (CAR) upon payment.
Payment of Local Taxes
The local treasurer collects transfer tax (usually 0.5%–0.75% of the selling price or zonal value, depending on the LGU ordinance).
Transfer of Tax Declaration
The parties present the notarized Deed of Absolute Sale, CAR, approved subdivision plan, and proof of tax payments to the provincial or city assessor’s office. The assessor cancels the old Tax Declaration and issues:
- A new Tax Declaration in the buyer’s name for the sold portion.
- An updated Tax Declaration in the seller’s name for the remaining area.
Delivery and Possession
Physical possession and all pertinent documents (including the approved plan) are delivered to the buyer. The buyer pays the new real property taxes starting the following year.

Tax Obligations and Fiscal Implications

Capital Gains Tax (6%): Borne by the seller; final tax on the gain.
Documentary Stamp Tax (1.5%): Also paid by the seller unless the contract provides otherwise.
Local Transfer Tax: Paid to the LGU treasurer.
Real Property Tax: Must be current; unpaid taxes become liens on the land.
Withholding Tax: Not applicable to ordinary sales between individuals unless the seller is a corporation or habitually engaged in real estate business.

Under-declaration of the selling price to reduce taxes is prohibited and may lead to BIR assessment plus penalties.

Risks and Legal Vulnerabilities

Because the land remains untitled, the buyer acquires only the seller’s rights—subject to any superior claim by the State or third persons. Double sales, forged prior deeds, overlapping Tax Declarations, and reclamation or public-domain issues are common pitfalls. The buyer cannot register the sale with the Register of Deeds and therefore cannot obtain a Torrens title immediately. Any future application for title (administrative free patent under Commonwealth Act No. 141 as amended or judicial reconstitution) will require the buyer to prove continuous possession through the chain of deeds and Tax Declarations. Prescription periods continue to run; adverse claimants may still surface.

Best Practices and Protective Measures

Engage a lawyer to review the chain of documents and draft the Deed of Absolute Sale with full warranties.
Require the seller to execute a Special Power of Attorney if any step will be handled by an agent.
Insert a clause in the deed allowing the buyer to withhold a portion of the purchase price until the new Tax Declaration is issued in the buyer’s name.
Conduct an ocular inspection and obtain an Affidavit of Adjoining Owners confirming boundaries.
Consider titling the entire land first through administrative or judicial proceedings before subdividing and selling; a Torrens title dramatically increases marketability and price.

The transaction, when properly documented and taxed, validly transfers ownership between the parties and creates a clean record in the assessor’s office. However, it leaves the buyer without the indefeasibility and security that only a Torrens title provides. Full compliance with survey, notarization, tax, and assessor requirements is therefore indispensable to protect both seller and buyer in the sale of a portion of land evidenced solely by Tax Declaration and Deed of Sale.
