US-CaliforniaWhat are the requirements for adverse possession in California?
To claim adverse possession in California, you must openly, continuously, exclusively, and hostilely occupy the property for at least 5 years while paying all property taxes.
What the Law Says
California law sets strict conditions for acquiring title to land through adverse possession. The claimant must meet several factual and legal requirements simultaneously for a statutory period.
Adverse possession in California is governed primarily by Civil Code sections 320–329 and Code of Civil Procedure section 318. To succeed, the possessor must show that their use of the property was (1) open and notorious, (2) hostile (without the owner’s permission), (3) exclusive, (4) continuous, and (5) accompanied by payment of all assessed property taxes for the statutory period.
The required period of possession is five years — but only if the claimant has paid all taxes levied on the property during that time. If taxes were not paid, no adverse possession claim can succeed, regardless of how long the occupation lasted.
Importantly, 'hostile' does not mean aggressive or violent; it means the possession is inconsistent with the true owner’s rights — i.e., without license, permission, or agreement from the owner.
Statutory TextNo action for the recovery of real property, or for the recovery of the possession thereof, can be maintained unless it appears that the plaintiff, his ancestor, predecessor, or grantor, was seized or possessed of the property in question within five years before the commencement of the action.
— Code of Civil Procedure, s. 318 — Limitation of actions for recovery of real property
Statutory TextFor the purpose of constituting an adverse possession, by a person claiming a title founded upon a written instrument, or a judgment or decree, land is deemed to have been possessed and occupied for the purpose of constituting an adverse possession only when it has been protected by a substantial inclosure, or when it has been usually cultivated or improved.
— Civil Code, s. 325 — Possession under written instrument or judgment
Statutory TextWhere it is shown that a person, or those under whom he claims, paid the taxes assessed upon the land for five years, evidence of such payment shall be prima facie evidence that the possessor was in possession of the land for the same period.
— Civil Code, s. 326 — Effect of payment of taxes
What Courts Have Said
California courts have consistently emphasized that adverse possession is disfavored and strictly construed against the claimant.
The court held that mere occupancy without payment of taxes cannot satisfy adverse possession, even after decades — tax payment is mandatory under Civil Code § 326.
Confirmed that 'hostile' possession means asserting ownership contrary to the true owner’s interest — not requiring animosity, but unequivocal conduct inconsistent with permission.
What to Do
Confirm you have occupied the property openly, continuously, and exclusively for at least 5 years.
Obtain certified records showing you paid all property taxes on the parcel for each of those 5 years.
Gather evidence of your possession (photos, witness statements, improvements, utility bills).
File a quiet title action in superior court to legally establish ownership — adverse possession is never automatic.
Consult a real estate attorney early: courts rarely grant these claims, and procedural missteps are fatal.
