Quick answer

You register an adverse claim by preparing a sworn written statement describing your claimed interest in the land and filing it with the Register of Deeds where the property is located. Once annotated, the claim is effective for thirty days, and it protects your interest by putting the world on notice — but it does not, by itself, prove your claim or create a permanent hold on the title.

An adverse claim is a fast, relatively inexpensive way to place the world on notice that you claim an interest in a piece of registered land — without having to file a court case first. It will not resolve a dispute on its own, but it buys time and removes an opposing buyer’s ability to later call themselves an innocent purchaser. Here is how to actually register one.

What an Adverse Claim Does

Under the Property Registration Decree, registered land operates on the principle that whatever is annotated on the title binds the whole world, while whatever is not annotated generally does not. An adverse claim under Section 70 lets someone who claims an interest in registered land — adverse to the registered owner, and arising after the original registration — place that claim directly on the certificate of title. Once annotated, anyone who later deals with the property is deemed to know about your claim, which strips away their ability to argue they were an innocent purchaser for value. That single effect is usually the whole point of filing one: it does not resolve who is right, but it forces anyone dealing with the property afterward to deal with your claim rather than ignore it.

Who May File One

Section 70 is written broadly: “whoever claims any part or interest in registered land adverse to the registered owner” may file, so long as the right or interest being claimed arose after the original registration of the land, and there is no other, more specific provision in the Decree for registering that particular kind of claim (for instance, an actual sale or mortgage should be registered as such, not as an adverse claim). In practice, adverse claims are commonly used by buyers under an unregistered contract to sell, co-owners or heirs whose share is being disposed of without their consent, and anyone with a colorable claim to the property who has not yet filed — or is preparing to file — a court case to establish it.

Step-by-Step: How to Register an Adverse Claim

The 30-Day Clock and What Happens After

An adverse claim is deliberately temporary. Section 70 provides that the claim is effective for a period of thirty days from the date of registration. Before that period lapses, the claimant may voluntarily withdraw it by filing a sworn petition to that effect with the Register of Deeds. After the thirty days lapse, the annotation may be cancelled upon the filing of a verified petition by any party in interest — typically the registered owner or a prospective buyer who wants the title cleared. Importantly, the lapse of thirty days does not automatically erase the claim from the title; cancellation still requires that verified petition, which gives the claimant an opportunity to be heard before the annotation disappears.

Frivolous Claims and the Penalty for Abuse

The law does not let claimants annotate frivolous claims without consequence. Section 70 provides that if, after notice and hearing on a petition to cancel, a court finds that the adverse claim was frivolous, it may fine the claimant an amount of not less than one thousand pesos (₱1,000) nor more than five thousand pesos (₱5,000), at the court’s discretion. The law also bars re-filing: once an adverse claim has been cancelled, no second adverse claim based on the same ground may be registered by the same claimant. This is meant to prevent adverse claims from being used as a harassment tool to cloud a title indefinitely by refiling the same claim every thirty days.

Adverse Claim Versus Other Annotations

An adverse claim is not the only way to protect an interest in land, and it is worth knowing when a different tool fits better. If you have already filed a court case affecting title to or possession of the property, a notice of lis pendens is generally the better tool — it is not limited to thirty days, and it stays annotated for as long as the case is pending. If you hold a money judgment against the registered owner, the appropriate annotation is a levy on execution made by the sheriff, not an adverse claim. And if your interest arises from an actual, completed transaction — a sale, a mortgage, an easement — that transaction should generally be registered directly as such rather than through an adverse claim, since Section 70 itself only applies where “no other provision is made in this Decree for registering the same.”

Common Mistakes When Filing

The most frequent reason an adverse claim runs into trouble is an incomplete sworn statement — leaving out the certificate of title number, describing the claimed interest too vaguely, or omitting a valid address for notices. Because Section 70 lists specific, mandatory contents, the Register of Deeds can decline to annotate a statement that leaves any of them out, so it is worth reviewing the draft against the six requirements before it is notarized rather than after. Another common error is treating the adverse claim as a substitute for the underlying court action it is meant to protect — the thirty-day window exists precisely because an adverse claim is not, on its own, a permanent solution, and claimants who let it lapse without taking further action often find themselves back where they started once the annotation is cancelled.

If You Are on the Other Side: Dealing With an Adverse Claim on Your Title

If you are a registered owner or a prospective buyer and discover an adverse claim annotated on a title you are dealing with, you generally have two options. You can wait out the thirty-day period, after which the claim may be cancelled upon a verified petition if the claimant does not take further action to protect the underlying right being asserted; or, if you believe the claim is groundless, you can file the verified petition to cancel it yourself, which triggers the notice-and-hearing process where a court can assess whether the claim was frivolous and, if so, impose the fine Section 70 provides for. Either way, a pending adverse claim is not something a buyer should simply ignore or work around — it is exactly the kind of notice the law intends buyers to take seriously before completing a transaction.

Fees and Practical Notes

The Registry of Deeds collects an entry or registration fee when the adverse claim is filed, assessed under the current Land Registration Authority fee schedule in effect at the registry where you file; because that schedule is periodically updated, it is best confirmed directly with the Register of Deeds concerned or the LRA rather than relying on a fixed figure. Bring at least two original notarized copies of the sworn statement (one for the registry’s file, one stamped as your receiving copy), a photocopy of the certificate of title if you have access to one, and a valid ID.

Practical Takeaways

Frequently Asked Questions

How long does an adverse claim stay on the title? It is effective for thirty days from the date of registration. After that, it may be cancelled upon a verified petition filed by any interested party, though the cancellation itself still requires notice and, if contested, a hearing.

Does registering an adverse claim prove that my claim is valid? No. An adverse claim only serves as notice to the world that you assert an interest in the property; it does not adjudicate whether that interest actually exists. Establishing the claim itself requires the appropriate court action.

Can I file another adverse claim if my first one is cancelled? No. Section 70 of the Property Registration Decree expressly bars registering a second adverse claim based on the same ground once the first has been cancelled, precisely to prevent the annotation from being used to harass a titleholder indefinitely.

What is the difference between an adverse claim and a notice of lis pendens? An adverse claim is a standalone sworn statement that lasts thirty days and does not require a pending case; a notice of lis pendens requires an actual case already filed in court affecting the title or possession of the land, and it remains annotated for as long as that case is pending.
