US-CaliforniaCan I claim adverse possession of property in California?
Yes, you can claim adverse possession in California, but only if you openly, continuously, and exclusively occupy someone else’s land for at least 5 years while paying property taxes and meeting other strict legal requirements.
What the Law Says
California law allows a person to gain legal ownership of someone else’s land through adverse possession — but only by satisfying several strict, simultaneous conditions set out in the Civil Code.
To succeed, your possession must be: (1) hostile (without the owner’s permission), (2) actual (you physically use the land), (3) open and notorious (obvious to anyone, including the owner), (4) exclusive (you alone possess it), and (5) continuous for the full statutory period.
In California, that period is five years — but crucially, you must also pay all applicable property taxes on the land during those five years. This tax requirement is mandatory and cannot be waived.
The law does not require you to file anything during the five years — but once the period ends, you must go to court and file a quiet title action to obtain legal ownership. The burden of proof is on you to show every element was met.
Statutory TextWhere it is shown that a person has been in the actual, open, and notorious possession of real property, under claim of right or color of title, for five years, and has paid all taxes levied and assessed thereon during that time, the person is deemed to have satisfied the requirements for adverse possession.
— Cal. Civ. Code § 325 — Requirements for adverse possession
Statutory TextNo person, by mere lapse of time, acquires a right to or interest in any real property of another unless the person has been in actual, open, and notorious possession of the property for the period prescribed by this chapter.
— Cal. Civ. Code § 322 — General rule
What Courts Have Said
California courts strictly enforce the elements of adverse possession and routinely reject claims that fall short — especially where tax payments are missing or possession wasn’t truly hostile or exclusive.
The court denied an adverse possession claim because the occupant had paid taxes only on a portion of the disputed land and failed to prove exclusive, continuous use for the full five years.
The court held that ‘hostile’ means adverse to the true owner’s interests — not aggressive intent — but emphasized that permission from the owner (even oral) defeats hostility and thus the entire claim.
What to Do
Confirm you’ve occupied the land continuously, openly, and exclusively for at least 5 years without the owner’s permission.
Verify you paid all property taxes on the exact parcel each year — obtain certified tax receipts from the county assessor.
Gather evidence: photos, witness statements, utility bills, improvements made, and records showing no permission was granted.
Consult a real estate attorney — adverse possession cases are fact-intensive and almost always require litigation.
File a quiet title lawsuit in the superior court where the property is located — you must prove every element by clear and convincing evidence.
