California is the most populous state in the country, with booming real estate markets in both the major cities and more rural areas. But whether you own a townhouse in San Francisco or a large suburban home outside of Los Angeles, you likely have two or three neighbors around your property. Under California law, these neighbors could gain possession of parts of your property under a legal doctrine known as adverse possession.
Adverse possession essentially allows a trespasser onto a piece of land to gain ownership of that land if the true owner fails to object within a certain period of time and if the trespasser pays faithful property taxes on the subject land.
To make sure that all of your land remains yours, it makes sense to keep an eye on your property lines. Or, you yourself might eventually want to assert a claim for adverse possession against another individual's land. Either way, you'll need to learn about California's adverse possession laws.
Adverse possession is a legal concept that allows a trespasser—sometimes a stranger but more often a neighbor—to gain legal title over someone else's land. The concept first developed centuries ago, in early Britain. It has been kept alive in order to achieve a fair result when one owner left a piece of land idle or unused, while another has been tending to it for so long that to make him or her leave would seem unfair, or create hardship.
In California, adverse possession is defined and regulated both by statute and by state courts.
Of course, there are hurdles to clear before someone can claim a piece of your California land using this theory. For one, the burden of proof is on the trespasser. In other words, if you hold legal title to a piece of land, you are its presumed owner until and unless the adverse possessor can come up with enough compelling evidence and arguments to convince a judge to give him or her ownership over all or a portion of it; most likely in the context of you suing to oust that person.
Adverse possession should not be confused with having an easement to use another person's property—for example, when your next-door neighbors have an easement to use your driveway to access their property. Easements involve shared rights with others in pieces of property, whereas adverse possession results in a shift in title, and the corresponding right to exclude others from the property.

In the Golden State, a combination of statutory language and court decisions dictate the elements that a trespasser must establish in order to prove adverse possession. As in most states, adverse possession in California is established from the nature of a trespasser's possession and the length of time the person possesses the land.
A trespasser's possession must, in California, be:
The final requirement, payment of property taxes, is often the biggest hurdle to someone claiming adverse possession, since it's unlikely for local government tax authorities to switch a portion of someone's property to a neighbor's tax bill.
What should you do if you spot a trespasser or a neighbor encroaching on your California land? Your first move, of course, is to speak with the person and ask them to remove all structures from, and refrain from entering onto, your property. If it's an innocent mistake, they are likely to comply.
If the trespass continues, you might want to consult a lawyer and bring an action to quiet title. This is a legal method for determining the rightful owner of land.
You'd be asking a California state court judge to issue an order declaring that you, and not the trespasser, are the true owner (and title holder) of the land. This order is particularly helpful if you are seeking to sell your property and will need to reassure potential buyers.
Any property that is held by California's state and local government entities is typically immune from adverse possession actions. Therefore, if you live next to an undeveloped portion of Big Basin Redwoods State Park, you won't be able to "annex" a larger yard by building a shed and waiting five years. California's government always has first priority when it comes to ownership.
