Short answer. Only unenforceable, not void. Under Article 1403, a sale of real property that is not in writing is an unenforceable contract, listed among those that bind once they are ratified. So a verbal land sale is not a legal nullity — it exists and can become fully enforceable once ratified, unlike a contract that is void from the start.
What the law says
The following contracts are unenforceable, unless they are ratified:

Unenforceable is a distinct category
Philippine law recognises several grades of defective contracts, and they are not the same. A void contract is a legal nothing — it produces no effects and cannot be cured. A verbal land sale does not fall there. Article 1403 opens by saying The following contracts are unenforceable, unless they are ratified: and then lists agreements under the Statute of Frauds, including the sale of real property not in writing. The label unenforceable is the key. The contract genuinely exists and is not void; what it lacks is the written proof needed to compel it in court. That missing element can be supplied later, which a void contract's fatal defect never can.
Why the difference matters
The distinction has real consequences. Because a verbal land sale is only unenforceable and not void, it can ripen into a fully enforceable contract through ratification. It is not stuck in permanent invalidity. This also affects who can complain and how. Only a party to the contract can raise the Statute of Frauds as a defence, and it must be raised properly and in time; it is not a defect the law notices on its own the way it treats a void agreement. Treating the two as interchangeable leads people to wrongly assume a verbal land deal is worthless, when in fact it stands on the verge of enforceability.
How ratification happens
A verbal land sale is ratified in more than one way. If, in a lawsuit, the party being sued fails to object to oral evidence of the agreement, the objection is waived and the contract becomes enforceable. Ratification also occurs by accepting benefits under the contract. Most importantly, the Statute of Frauds applies only to agreements still wholly unperformed. Once there has been partial or full performance — the buyer pays and the seller accepts, or possession is delivered — the sale is taken out of the Statute entirely and may be enforced despite the absence of a writing. At that point the earlier lack of a document no longer stands in the way.
The practical bottom line
So the honest answer to a worried buyer or seller is that a verbal land sale is not dead; it is vulnerable. Left wholly on words, it cannot be forced through the courts over the other side's objection. But it is not void, and it can be rescued by ratification or by performance, or simply by putting it in a signed writing. If you are the one wanting to enforce it, act to secure a signed document or evidence of performance; if you are the one resisting, know that the defence must be timely and can be lost. The category — unenforceable, not void — is what keeps the deal alive.
