How Long Must You Use Someone Else’s Land and Buildings to Acquire Ownership by Adverse Possession, and What Are the Requirements?

In legal terms, adverse possession is the acquisition of ownership of another person’s property through possession that meets the legal requirements—not through purchase or transfer. Put simply, even if you have been using someone else’s land or building for a long time, it does not automatically mean you have acquired rights, unless that possession fully satisfies all elements prescribed by law.

The core requirements for adverse possession for land and buildings consist of four main points, all of which must be met together:

1. Time period: possession must be continuous and uninterrupted for the entire period of 10 years.

2. Peaceful possession: meaning the possession is not obtained by force or disturbance, or by seizing/contesting in a manner that makes the owner’s possession abnormal.

3. Open possession: possession that is visible to the public—not concealed or secretly held; for example, actually living there, actually using the property, and maintaining or improving it in an open manner.

4. Intent to own: this point is very important, because if you enter and live on or use the land as a lodger, borrower, tenant, or with the owner’s permission—including cases where the circumstances show that you still acknowledge the original owner as the owner—then, in general, it will not be considered possession with intent to own. Therefore, it often does not meet the requirements for adverse possession

In addition, the law also explains interruption of possession: if the possessor is dispossessed involuntarily—for example, being evicted or having the area seized—but is able to regain possession within 1 year, or files a lawsuit to recover possession within 1 year, then this may still not be counted as an interruption of possession.

The question “How long have you lived there?” is a common starting point for misunderstandings, because counting time alone is not enough. However, if we look only at the legal time requirement, it can be summarized as follows: the land and buildings must be possessed continuously for a full 10 years, and the possession must be peaceful, open, and with the intention to own, in order to fall within the framework of adverse possession.

A key point to watch out for is the word “continuously.” In practice, it does not mean merely being on the property from time to time; it means holding and using it on an ongoing basis like an owner—for example, maintaining it, making improvements, actually using the property regularly, and having no lapse in possession that would be considered an interruption. Because if possession is interrupted, the time count may have to start over, resulting in failure to meet the requirements for adverse possession, even if you have lived there for many years in total.

Another point that should be clearly distinguished is that the 10-year period applies only to immovable property. Movable property has a different time requirement. But in the context of this article, which focuses on land or a house, the main rule to remember is 10 uninterrupted years, together with all elements: peaceful, open, and with the intention to own.

In practice, cases involving adverse possession are often not decided by whether the full 10 years have elapsed, but by the facts as to whether the possession satisfies all key elements—especially these three core points that are at the heart of the conditions for adverse possession for land and buildings.

1. Peaceful possession

“Peaceful” does not mean there can be no dispute at all throughout the 10-year period. Rather, it must be possession that does not arise from the use of force, or from an abnormal manner of holding that indicates the possession is unlawful in nature. Simply put, it is possession in a condition that the general public can see as “actually being held and used,” not a continuous tug-of-war that keeps the state of possession unstable.

2. Open possession

“Open” means possession that is not concealed, so that the surrounding community can perceive it—for example, regularly entering and using the area, maintaining it, repairing it, improving it, or making use of it in a way that is ordinarily visible. The importance of this principle is that the possession is not a secret holding where the original owner has no opportunity to know of it or object.

3. Intention to be the owner

This point is often decisive, because if the area is used as an authorized occupant—such as by renting, borrowing, or residing with the owner’s consent—the circumstances indicate that it is not held as if one were the owner, and therefore does not satisfy the elements of adverse possession, even if it has been for a long time. Conversely, if all circumstances show that the property is used and cared for like an owner would, without acknowledging the authority of the original owner, this point carries significant weight.

4. Continuous and uninterrupted possession

Even if the above elements are satisfied, if the possession is interrupted, the time calculation may be affected. The law provides principles on involuntary loss of possession and re-entry into possession within a prescribed timeframe, which is a point that requires a detailed review of the facts in each case.

Although the principle of adverse possession sets a 10-year period for land and buildings, in real cases the time count is often where people make mistakes. This is because the law uses the term possession without interruption (Uninterrupted Period), and it also clearly specifies what circumstances are considered an interruption or not, as follows:

1. Possession must be continuous, not occasional use

Possession that can be counted must reflect holding and use on a continuous basis as if the possessor were the owner—not going in to use it from time to time and then disappearing, to the point that there is no consistent state of possession. This directly affects the adverse possession requirement of uninterrupted possession.

2. What causes possession to be interrupted

As a general rule, if the possessor stops intending to possess, or no longer holds the property, the possession may come to an end. However, if the possessor is only temporarily obstructed due to a temporary cause, the possession may still not be deemed to have ended.

3. Losing possession involuntarily but recovering it within 1 year may not be counted as an interruption

This is a very important point for completing the 10-year period, because the law provides that “possession shall not be deemed interrupted” if the possessor is dispossessed involuntarily and then re-enters into possession within 1 year from the date of dispossession, or files a lawsuit to recover it within 1 year.

4. If possession is transferred, can the time be carried over?

The law allows a transferee of possession to aggregate the transferor’s period with their own. This is the point that, in many cases, means you do not have to start counting from day one again. However, be aware that defects in the transferor’s possession may also be raised as a defense against the transferee.

5. Always check the type of property first, because some property cannot be acquired by adverse possession

In practice, many cases where people are confident that “we’ve been here a long time, so we should be entitled to it” actually do not qualify as adverse possession because they fail to meet certain key requirements, or because the property is of a type that the law does not allow to be acquired by this method from the outset. Clearly separating the issues helps you quickly assess whether you truly meet the requirements for adverse possession.

1. State land or land used for public benefit

Certain types of property—especially public property of the State or property reserved for the common use of the public—are not in the category that can be acquired by adverse possession, no matter how long they have been used or occupied. This point is very important because it is a structural limitation that prevents the case from even reaching consideration of other elements.

2. Occupying with a legal basis granted by the original owner, such as renting, borrowing, or permission

The core of adverse possession is possession as if you were the owner. If you move in or use the land while acknowledging that the original owner still has rights—such as renting a house, borrowing land to build a house, or being granted temporary permission to use it—those circumstances conflict with the element of intent to possess as owner. This means you fail a key requirement, even if you have lived there for a long time and maintained it continuously.

3. Possession is not open, or is concealed

If holding the property is done in a concealed manner—secretly using it or preventing the public or the original owner from having an opportunity to know and object—this often fails the “open” element, which is central to the requirements for adverse possession for land and buildings.

4. Possession is interrupted, or there is a period where actual control is lost

Even if you have the intent to possess as owner and have used the property for a long time, if the possession is disrupted to the point that it is considered interrupted, the time calculation becomes problematic and, in some situations, may need to start over. This is why many people add up the years and find they exceed 10, but in terms of the actual facts they still fail because the possession is not continuous as required by law.

5. Using an area without clarity as to ownership, and being unable to prove the boundaries

Adverse possession requires proof of where you possess and the extent of the boundaries. If the boundaries of the area possessed are unclear—for example, using only part of the area without certainty, or having insufficient boundary evidence—it becomes difficult to prove the right, even if other elements are met.

As a matter of law, once the facts satisfy all required elements—such as possessing another person’s land or building peacefully and openly, with the intention to own it, continuously for a full 10 years—the possessor may acquire ownership under this approach. In real life, however, the point where many people stumble is that having the right in principle and making that right practically enforceable within the land registration system and against third parties are two different things. There are three main reasons:

1. The facts must be proven—it is not enough to merely claim you have lived there for a long time

A claim based on adverse possession can almost always be challenged on the grounds that the elements are not fully met—for example, the possession was not truly open, or the occupier moved in with permission and therefore lacked the intention to own. This means the requirements for adverse possession must be proven through circumstances and evidence, not by statements alone.

2. Land is immovable property; the registration system affects confirmation of rights

Even if you believe you have already acquired ownership by meeting all conditions, in practice, having that right recognized and using it for further actions—such as sale, transfer, or mortgage registration—usually requires clear documentary support or a definitive ruling, because the counterparty or relevant parties will want verifiable evidence.

3. In many cases, a court decision is required because there are disputes over boundaries and the status of possession

Many adverse possession cases do not argue only about whether 10 years have been completed; they also dispute where the possession occurred, the extent of the boundaries, and whether the possession was truly continuous or interrupted. When there is a dispute, the court is the mechanism that enables the facts to be formally determined.

In cases or disputes involving adverse possession, verifiable evidence is essential because the court and the opposing party will consider whether the evidence reflects possession that is continuous, open, peaceful, and with an intention to own. Therefore, evidence preparation should be done systematically and tied to the elements of the requirements for adverse possession—not merely a scattered set of documents that fails to tell a coherent story.

1. Witness testimony

Witnesses often serve as the link that connects the story and shows a picture of continuous and open possession—especially neighbors, the village headman, community committee members, or people who have seen the property actually used for a long time. The key is that witnesses should be able to provide specific details, such as who they saw using the land, since when, how it was used, and whether anyone objected, rather than making broad statements like “they’ve been there a long time.”

2. Documents showing use and maintenance of the property

These documents help show possession as if the possessor were the owner, not merely temporary occupation—for example, receipts for construction materials, repairs, extensions, fences, internal roads, agricultural plots, or contractor/service agreements, with clear dates and locations. Good documentation should show continuity in intervals throughout the entire period, not only at the beginning and then disappearing.

3. Photos or videos organized as a timeline

Photos and videos carry weight when they can be arranged into a timeline, such as before-and-after images of improvements, images showing actual residence, and images showing seasonal use, together with date/time information or supporting witnesses. The key is that the images should be consistent regarding the boundaries and the manner of use, to support that the possession was open and continuous.

4. Water and electricity bills, or other location-tied service records

If electricity, tap water, or other services tied to the property’s location have been used continuously, these records can strongly reflect regular, actual residence or use. However, care must be taken to ensure the account holder’s name and the address/house number match the area claimed to be possessed, and that they do not conflict with other facts—for example, showing a different address or frequent changes of the account holder that make the narrative inconsistent.

5. Tax evidence and dealings with government agencies as the property’s caretaker

Certain tax documents or records of contact with government agencies can increase credibility that the property has been used openly and in fact—especially when the information is clearly tied to the property or area. However, having tax receipts does not automatically mean the requirements are met; they must be used together with other evidence to show the overall picture of continuous possession and an intention to own.

6. Boundary evidence, maps, survey images, and location-identification documents

A point that causes many cases to stumble is: where exactly is the possession, and how large is the area? Because claiming adverse possession requires clear boundaries. Evidence that helps greatly includes maps, time-stamped satellite images, survey documents, or consistent boundary evidence. If the boundaries are unclear, even a long history of use can still be difficult to prove.

7. Evidence of disputes, objections by the original owner, or the possessor’s responses

Demand letters, notices, chat messages, or written correspondence may become important evidence in two ways. On one hand, they can show that a dispute exists and may affect whether the possession was peaceful. On the other hand, they can show how the possessor responded—for example, asserting a right as their own, or admitting they were merely staying with permission—which directly touches on the element of intention to own. Therefore, this group of documents should be compiled in full and clearly arranged in chronological order.

An overview of adverse possession for land and buildings is not determined solely by how long someone has occupied the property, but by the fact that the possession has been continuous for a full 10 years and meets the requirements for adverse possession in full—especially that the possession is peaceful, open, and carried out with consistent intent to own throughout the period for which the right is claimed.

What prevents many cases from moving forward often lies in the details, such as interruptions in possession; moving in with a legal basis granted by the original owner (e.g., renting, borrowing, or having permission); or being unable to clearly prove the boundaries of the area and the sequence of events. Therefore, making an accurate assessment from the outset and preparing evidence that can tell a coherent, continuous story will help reduce risk and make the decision to proceed more precise.
