Unregistered Deed of Sale: Your Rights in the Philippines

A notarized deed of sale that was never registered still binds the seller and the seller’s heirs, but it does not bind anyone else. Against third persons — a second buyer in good faith, a creditor who levies on the land, a bank that takes a mortgage — registration is what counts (PD 1529, Sec. 51). Until you register, annotate an adverse claim or sue to compel, your purchase is exposed.

This guide is for buyers who have a notarized deed but whose title is still in the seller’s name. If your deed was never notarized at all, start with our guide on whether an unnotarized deed of sale is valid.

The answer at a glance

• Right/Rule: An unregistered deed affecting titled land “shall operate only as a contract between the parties and as evidence of authority to the Register of Deeds to make registration”; registration “shall be the operative act to convey or affect the land insofar as third persons are concerned” (PD 1529, Sec. 51).
• Defense/Exception: A second buyer who knew of your earlier sale cannot rely on registering first, because Article 1544 requires good faith. But a creditor’s registered levy on attachment beats your earlier unregistered sale (Valdevieso v. Damalerio, G.R. No. 133303, 17 February 2005).
• Evidence: The notarized deed, proof of payment, the seller’s owner’s duplicate title (or proof of who holds it), tax and possession records, and any proof that a later buyer knew of your purchase.
• Deadline/Forum: PD 1529 sets no deadline to register, but every day of delay is risk. An action on a written contract prescribes in ten years from accrual (Civil Code, Art. 1144). Petitions about the title are filed in the court where the land lies.
• Next step: Get a certified true copy of the title today. If it is clean, register the deed now; if you cannot, annotate an adverse claim.

Is an unregistered deed of sale still valid between you and the seller?

Yes. Registration is not what makes a sale valid. The sale was perfected when you and the seller agreed on the property and the price, and a notarized deed of sale is a public instrument whose execution “shall be equivalent to the delivery of the thing” unless the deed shows otherwise (Civil Code, Art. 1498). Ownership passes to the buyer on actual or constructive delivery (Art. 1477).

So, as between you and the seller, you are the owner. The seller cannot sell or mortgage the land again without breaching your contract, and the seller’s heirs inherit that obligation: contracts take effect between the parties, “their assigns and heirs” (Art. 1311). If the seller refuses to cooperate with the transfer, you can compel the seller to do what the transfer requires (Art. 1357; PD 1529, Sec. 107, discussed below).

The problem is everyone else. On titled land, Section 51 of PD 1529 says plainly that no deed “shall take effect as a conveyance or bind the land” until it is registered. To the outside world, the seller still owns the property.

Who wins when someone else claims the same land?

The table below shows the usual result for titled land. Each row assumes your notarized deed is genuine and earlier in date than the other person’s claim.

Second buyers. When immovable property is sold twice, ownership belongs to the buyer “who in good faith first recorded it in the Registry of Property” (Art. 1544). In Blanco v. Rivera (G.R. No. 145878, 25 April 2006), the first buyer bought a co-owner’s undivided share in 1977 but could not register, allegedly because the other co-owner held the owner’s duplicate title and would not surrender it. In 1980 the seller sold the same share to that other co-owner, who registered and got a new title. The Supreme Court ruled for the second buyer because there was no proof he knew of the earlier sale. It also said the first buyer could have annotated an adverse claim or sued, and was guilty of laches after more than 14 years of inaction. Quoting earlier rulings, the Court stressed the other side of the rule: knowledge gained by the second buyer of the first sale “defeats his right even if he is first to register,” because that knowledge taints the registration with bad faith. For the full double-sale rules, see Article 1544 double sale.

The seller’s creditors. This is the risk buyers most often overlook. In Valdevieso v. Damalerio, the buyer bought titled land in December 1995 and declared it for tax purposes, but registered only in June 1996. In between, the seller’s creditor had the land attached and the levy annotated on the title. The Court held that “levy on attachment, duly registered, takes preference over a prior unregistered sale,” and that the preference is “not diminished even by the subsequent registration of the prior sale.” The buyer’s new title carried the attachment. A buyer in that position can be left with only a claim against the seller.

The registered owner’s side. A deed from someone who is not the registered owner is weaker still. In Sumampong v. Heirs of Sumampong-Sarate (G.R. No. 277682, 5 February 2026), the occupant had a notarized 1966 deed from a third person, a house on the land, a tax declaration and tax receipts. The Court held that these “cannot prevail over a certificate of title,” and that the registered owner’s heirs could recover possession because an action to recover registered land does not prescribe and was not barred by laches. Always confirm that your seller is the person named on the title — see how to verify a land title.

What if the land has no Torrens title?

For land not registered under the Torrens system, no deed “shall be valid, except as between the parties thereto,” unless it is recorded with the Register of Deeds where the land lies (PD 1529, Sec. 113). Recording is done in a separate registration book, and it is “without prejudice to a third party with a better right.” So the same advice applies: record the deed promptly, and keep proof of possession and tax payments. Our guide on land title vs tax declaration explains why a tax declaration alone is not proof of ownership.

Why do deeds stay unregistered, and what fixes each problem?

How does an adverse claim protect you while you cannot register?

Section 70 of PD 1529 lets anyone who claims an interest in registered land adverse to the registered owner file a sworn statement with the Register of Deeds. It must state your right and how you acquired it, the title number, the registered owner’s name, a description of the land, your residence and an address for notices. Once annotated, it warns everyone who checks the title.

Section 70 says the adverse claim is “effective for a period of thirty days from the date of registration.” The Supreme Court has read this together with the next sentence, which says the annotation “may be cancelled upon filing of a verified petition.” In Sajonas v. Court of Appeals (G.R. No. 102377, 5 July 1996), the Court held that cancellation is still needed to make the adverse claim ineffective; otherwise the annotation remains and continues as a lien on the property. In that case, buyers whose adverse claim was annotated before a creditor’s levy kept the land free of the levy.

Use it honestly. A court that finds an adverse claim frivolous may fine the claimant not less than ₱1,000 nor more than ₱5,000 (Sec. 70), and after cancellation the same claimant cannot register a second adverse claim on the same ground. For how adverse claims compare with a notice of lis pendens, see adverse claim vs lis pendens.

Your options and what to do next

Option 1 — Register now (seller cooperative or title in hand). Pay the taxes on the sale at the BIR Revenue District Office where the land lies and secure the BIR’s electronic Certificate Authorizing Registration (eCAR). Then present the notarized deed, the owner’s duplicate title, the eCAR and the other documents the Register of Deeds lists, and pay the registration fees. The Register of Deeds cancels the seller’s title and issues a new one in your name. The owner’s duplicate presented with the deed is “conclusive authority” for the Register of Deeds to issue a new title (PD 1529, Sec. 53). See who pays the taxes and fees in a property sale and the property purchase timeline. Ask the RDO and the Registry for their current checklists; requirements and fees change.

Option 2 — Annotate an adverse claim (you cannot register yet). If the seller holds the title and will not release it, or taxes are still being processed, file a sworn adverse claim under Section 70 at the Register of Deeds. Do this immediately if you suspect another sale, a mortgage or a pending case against the seller.

Option 3 — Demand, conciliate, then go to court (seller refuses). Send a written demand asking the seller to surrender the owner’s duplicate and sign the tax forms by a fixed date. If you and the seller live in the same city or municipality, barangay conciliation is generally required before filing a civil action — see our guide to the certificate to file action. Your court remedies include a petition under Section 107 to compel surrender of the withheld duplicate (the court may order surrender or, if it cannot be delivered, annul the outstanding duplicate and order a new title), and an ordinary action for specific performance under Article 1357. If you file a case affecting the title, ask your lawyer about annotating a notice of lis pendens (PD 1529, Sec. 76).

Option 4 — Someone else has already registered. Get a certified true copy of the title and the registered documents. If a second buyer registered knowing of your sale, or a deed was forged, consult a lawyer at once about an action to cancel the later title or for reconveyance, with a notice of lis pendens. If a creditor’s levy was registered first, your realistic claim may be against the seller for the price and damages.

If you are the seller. Keeping the title after being paid in full exposes you to a Section 107 petition and a damages claim. If the buyer has not paid, put the unpaid balance in writing before releasing the title, and get advice on your remedies.

Where to go: the Register of Deeds for the province or city where the land lies (title copy, adverse claim, registration); the BIR Revenue District Office (transfer taxes); the Lupon of your barangay (conciliation); the court where the land lies (Section 107 petition or civil action); and the Public Attorney’s Office if you qualify for free legal help.

Documents to bring:

• The original notarized deed of sale and certified copies
• A certified true copy of the title (get a fresh one)
• Receipts or bank and e-wallet records of the price paid
• The latest tax declaration and real property tax receipts
• Proof of possession: photos, utility bills, barangay certification
• Your demand letter and the seller’s replies, especially any refusal to release the title
• Valid IDs and, for an adverse claim, your sworn statement

Deadlines: There is no fixed period to register, but the cases above show what delay costs: priority goes to whoever registers first in good faith, and long inaction can be treated as laches (Blanco). An action on a written contract, such as one to compel the seller to perform, must be brought within ten years from the time the right of action accrues (Art. 1144); a written extrajudicial demand interrupts the period (Art. 1155). BIR deadlines for the transfer taxes run separately — check them with the RDO.

First action today: Request a certified true copy of the title from the Register of Deeds and check its annotations (our guide to checking liens and adverse claims shows what to look for). If it is clean, start the BIR process this week; if it is not, or the seller is stalling, file an adverse claim.

Key takeaways

• A notarized but unregistered deed binds the seller and the seller’s heirs (PD 1529, Sec. 51; Civil Code, Arts. 1311, 1498).
• Against third persons, registration is the operative act (Sec. 51).
• A second buyer who registers first in good faith wins; one who knew of your sale does not (Art. 1544).
• A creditor’s registered levy beats your earlier unregistered sale (Valdevieso).
• If you cannot register yet, annotate an adverse claim; it stays until cancelled (Sec. 70; Sajonas).
• A seller who withholds the title can be compelled by court petition (Sec. 107).

Frequently asked questions

Am I the owner if my deed is notarized but not registered?
As between you and the seller, yes: executing a public instrument is equivalent to delivery (Art. 1498), and ownership passes on delivery (Art. 1477). Against third persons, the registered owner is still the seller until your deed is registered (PD 1529, Sec. 51).

Can the seller’s creditors take land I already bought?
Yes, if they register a levy or attachment before you register your deed. The Supreme Court held in Valdevieso v. Damalerio that a registered levy on attachment takes preference over a prior unregistered sale.

Does an adverse claim expire after 30 days?
Not automatically. In Sajonas v. Court of Appeals, the Court held that the annotation stays on the title until it is cancelled on a verified petition.

Is paying real property tax in my name enough to protect me?
No. In Sumampong, a deed, a tax declaration and tax receipts could not prevail over a certificate of title. Tax payments help show possession and good faith, but they do not replace registration.
