Is an Unnotarized Deed of Sale Valid in the Philippines?
Yes. A deed of sale that was never notarized is still a valid sale between the buyer and the seller, as long as they agreed on the property and the price. What the buyer gives up is protection: an unnotarized deed cannot be registered, is weaker proof in court, and does not bind a second buyer or the seller’s creditors. The buyer can compel the seller to sign a notarized deed (Civil Code, Art. 1357).
The answer at a glance
- Rule: Contracts bind “in whatever form they may have been entered into” if the essential requisites are present (Art. 1356). The public-document requirement for land (Art. 1358) is “only for convenience, not for validity or enforceability” (Dalion v. Court of Appeals, G.R. No. 78903, 28 February 1990).
- Exception: Some land transactions are void without the right form — a donation of land not made in a public document (Art. 749) and a sale of land by an agent whose authority is not in writing (Art. 1874).
- Evidence: The signed deed, receipts for the price, proof that you took possession, witnesses who saw the signing, and messages in which the seller acknowledges the sale.
- Deadline and forum: Actions on a written contract must be brought within ten years from the time the right of action accrues (Art. 1144); a written demand interrupts the period (Art. 1155). Barangay conciliation usually comes before court.
- Next step: Ask the seller to sign a notarized deed now, while they are available and cooperative. If they refuse, send a written demand.
Why is an unnotarized deed of sale still valid?
A sale in the Philippines is a consensual contract. As the Supreme Court put it in Dalion, a contract of sale “is perfected by mere consent” and “no particular form is required for its validity.” Once the buyer and seller agree on a determinate property and a price, each can demand that the other perform: the buyer can demand delivery and transfer of ownership, and the seller can demand payment. For the general rules, see our guide to how a contract of sale works.
Article 1356 of the Civil Code states the general principle: contracts “shall be obligatory, in whatever form they may have been entered into, provided all the essential requisites for their validity are present.” Form becomes “absolute and indispensable” only when the law itself makes it a condition of validity or enforceability.
Article 1358 does say that acts and contracts that create or transmit real rights over immovable property “must appear in a public document.” But the same paragraph says that sales of real property are governed by Articles 1403, No. 2, and 1405 — the Statute of Frauds — and the Supreme Court has read Article 1358 as a rule of convenience. In Dalion, the buyer’s only evidence was a 1965 private (unnotarized) deed of absolute sale. The Court upheld the sale and affirmed an order for the seller to deliver the land and execute a formal deed in a public document, failing which the sheriff would execute it on the seller’s behalf.
What the law does require for enforceability is a writing. Under the Statute of Frauds, an agreement “for the sale of real property or of an interest therein” is unenforceable by action unless it, or a note or memorandum of it, is in writing and signed by the party charged (Art. 1403(2)(e)). A signed private deed satisfies this. A purely verbal land sale does not, although it can be ratified by failure to object to oral evidence or by accepting benefits under it (Art. 1405). Our Statute of Frauds guide covers this in detail.
What does notarization actually add?
Notarization does not create the sale; it changes what the deed can do outside the relationship between buyer and seller. The comparison below shows the practical difference.
| Issue | Notarized deed | Unnotarized deed |
|---|---|---|
| Binding between buyer and seller | Yes | Yes, if consent, object and price are present (Dalion) |
| Registration with the Registry of Deeds | Registrable as a public instrument acknowledged before a notary (PD 1529, Sec. 112) | Not registrable as it stands |
| Effect on third persons (titled land) | Once registered, registration is the operative act against third persons (PD 1529, Sec. 51) | Operates only as a contract between the parties |
| Untitled land | Must still be recorded to bind others (PD 1529, Sec. 113) | Valid only between the parties |
| Proof in court | Admissible without further proof; the acknowledgment is prima facie evidence of execution (Rule 132, Sec. 30) | Due execution and authenticity must be proved first (Rule 132, Sec. 20) |
| Delivery of the property | Executing a public instrument is equivalent to delivery (Art. 1498) | Delivery must be shown another way, such as actual possession (Art. 1497) |
Under the 2019 Amendments to the Revised Rules on Evidence, public documents include “documents acknowledged before a notary public except last wills and testaments” (Rule 132, Sec. 19(b)); all other writings are private. The Supreme Court has stressed that notarization “converts a private document into a public document, making it admissible in evidence without further proof of its authenticity” (Spouses Tan v. Atty. Vallejo, A.C. No. 11219, 16 March 2022).
When does the missing form make the deal fail?
The “valid but unprotected” rule is for a sale signed by the owner. These situations are different:
| Situation | Rule | Result |
|---|---|---|
| Donation of land in a private document | A donation of an immovable must be made in a public document to be valid (Art. 749) | Void; it must be redone properly, and acceptance takes effect only during the donor’s lifetime |
| Land sold by an agent with verbal authority only | The agent’s authority must be in writing (Art. 1874) | The sale is void |
| Verbal land sale with nothing signed | Statute of Frauds (Art. 1403(2)(e)) | Unenforceable by action unless ratified (Art. 1405) |
| Deed notarized without the seller appearing | Signatories must personally appear and be identified (2004 Rules on Notarial Practice, Rule IV, Sec. 2(b)) | The notary may be disciplined; do not rely on the notarized deed’s presumption — be ready to prove the signing |
Other defects — a missing spouse’s consent, one co-owner or heir selling the whole property, or a “sale” that is really a loan — are separate problems that notarization does not cure. They are covered in common legal issues in property sales contracts.
What are the risks for a buyer holding an unnotarized deed?
- A second buyer can win. If the same land is sold twice, ownership goes to the buyer “who in good faith first recorded it in the Registry of Property” (Art. 1544). An unnotarized deed cannot be recorded, so a later buyer in good faith who registers first can defeat you. See double sale under Article 1544.
- The seller’s creditors can reach the land. For titled land, an unregistered deed “shall operate only as a contract between the parties” (PD 1529, Sec. 51). A levy or attachment registered against the seller’s title is constructive notice to everyone (Sec. 52).
- The seller may deny signing. Before a private document is received as authentic, you must prove it was duly executed — through someone who saw it signed, evidence that the signature is genuine, or other evidence (Rule 132, Sec. 20). A private document more than 30 years old, from proper custody and free of suspicious alterations, needs no further proof of authenticity (Sec. 21).
- The seller may die. Contracts take effect between the parties, their assigns and heirs (Art. 1311), so the heirs are bound — but proving the deed gets harder as witnesses become unavailable.
- The title stays in the seller’s name. The transfer process at the BIR and the Registry of Deeds works from a notarized deed. See who pays the taxes and fees in a property sale.
Your options and what to do next
Option 1 — The seller is cooperative: execute a notarized deed now. Have the seller sign a new deed of absolute sale (or a deed confirming the earlier sale) before a notary public. To be registrable, the deed must be signed in the presence of at least two witnesses who also sign, and acknowledged before a notary; if it has two or more pages, each page is signed on the left margin by the parties and witnesses and sealed, and the number of pages is stated in the acknowledgment (PD 1529, Sec. 112). Everyone who signs must appear personally and be identified, and the notary must not be a relative of a party within the fourth civil degree (2004 Rules on Notarial Practice, Rule IV, Secs. 2(b) and 3(c); Tan v. Vallejo applied Sec. 3(c) where the buyer was the notary’s relative). Then pay the transfer taxes and register. Our guides on when to sign the deed of absolute sale and the deed of sale checklist help here.
Option 2 — The seller refuses or stalls: demand, conciliate, then sue to compel. Once a sale is perfected, “the contracting parties may compel each other to observe that form,” and the right “may be exercised simultaneously with the action upon the contract” (Art. 1357). Where a public document is needed for registration, the parties may use this same right (Art. 1406). Start with a written demand giving a deadline to sign. If you and the seller live in the same city or municipality, barangay conciliation is generally required before filing. If that fails, file a civil action asking the court to order the seller to execute a public deed and deliver the property — as in Dalion, the court can direct the sheriff to sign if the seller will not. Which court hears the case depends on the relief sought and the property’s value, so get advice before filing.
Option 3 — The seller has died. The heirs are bound by the sale (Art. 1311). Ask them, or the estate’s administrator, to sign a confirmatory deed. If the estate is being settled, raise your claim there rather than waiting until the land has been partitioned or sold.
Option 4 — You suspect a second sale or a creditor’s claim. Get a certified true copy of the title from the Registry of Deeds and check the annotations (see how to verify a land title). Consult a lawyer immediately about protecting your claim on the title and about filing the action under Option 2.
If you are the seller. Your obligation to sign a public deed is part of a reciprocal sale. If the buyer has not paid what was agreed, put the unpaid balance in writing and review your remedies in our guide to the contract of sale before signing anything new.
Where to go: a notary public (to execute the deed); the Lupon of your barangay (conciliation); the Registry of Deeds where the land lies (title copy and registration); the BIR Revenue District Office (transfer taxes — ask for its current checklist); the Municipal Trial Court or Regional Trial Court (action to compel); and the Public Attorney’s Office if you qualify for free legal help.
Documents to bring:
- The original unnotarized deed and any copies
- Receipts, bank or e-wallet records of the price paid
- A certified true copy of the title, or the tax declaration for untitled land
- Proof of possession: tax receipts in your name, utility bills, photos, barangay certification
- Names and contact details of witnesses to the signing
- Texts, emails or letters in which the seller acknowledges the sale
- Government IDs of the parties for notarization
Deadlines: An action upon a written contract must be brought within ten years from the time the right of action accrues (Art. 1144); an action upon an oral contract within six years (Art. 1145). The period is interrupted by filing in court, by a written extrajudicial demand, or by the debtor’s written acknowledgment (Art. 1155). When the right of action accrues depends on the facts — for example, whether and when the seller refused to sign — so do not wait.
First action today: Make photocopies of the deed and your payment records, store the original safely, and send the seller a short written request to sign a notarized deed by a specific date.
Key takeaways
- An unnotarized deed of sale is valid and binding between buyer and seller (Arts. 1356, 1358; Dalion).
- It cannot be registered, so it does not protect you against a second buyer or the seller’s creditors (PD 1529, Secs. 51, 112, 113; Art. 1544).
- In court, you must first prove the deed was genuinely signed (Rule 132, Sec. 20).
- Donations of land and land sales by an agent without written authority are void without the required form (Arts. 749, 1874).
- You can compel the seller, or the seller’s heirs, to sign a notarized deed (Arts. 1311, 1357, 1406).

Frequently asked questions
Is a deed of sale signed only by the seller valid?
It can be. A deed of absolute sale is often signed only by the seller, and a writing signed by the party charged satisfies the Statute of Frauds (Art. 1403(2)(e)). But the buyer is still a principal party: in Tan v. Vallejo the Supreme Court rejected the argument that such a deed is a “unilateral contract of sale” needing only the sellers’ signatures, and disciplined the notary, who was related to the buyer.
Can I register an unnotarized deed of sale?
No. PD 1529, Sec. 112 makes deeds registrable when they are executed as public instruments, signed before two witnesses and acknowledged before a notary public or other authorized officer.
What if the deed was notarized but the seller never appeared before the notary?
The notarial rules require personal appearance and proper identification (Rule IV, Sec. 2(b)). A deed notarized in breach of the rules invites a challenge, so keep other proof of the signing and consider having a proper deed executed.
Does an old unnotarized deed still have value?
Yes. It still binds the parties and their heirs, and a private document more than 30 years old, produced from proper custody and free of suspicious alterations, needs no further proof of authenticity (Rule 132, Sec. 21). It still cannot be registered as it stands.
