Squatters Rights in Oregon: 10-Year Adverse Possession Law
Oregon requires 10 years of continuous, open, hostile possession, with no tax-payment or color-of-title requirement. A 2025 law, effective January 2026, newly allows squatters to be removed through Oregon's faster eviction process rather than a full ejectment lawsuit.

Recent Law Changes in Oregon
2025: House Bill 3522, signed June 20, 2025 and effective January 2026, allows a property owner to evict a squatter using Oregon's expedited Forcible Entry and Detainer (FED) process via a 24-hour written notice to vacate — previously, owners had to file a slower, more complex ejectment lawsuit. A related measure, Senate Bill 593, addresses adverse possession guidelines. This is a removal-process change; the underlying 10-year adverse possession period is stated to remain unchanged, but SB 593's specifics should be verified directly.
Oregon Adverse Possession Procedures
Making an Adverse Possession Claim
To establish adverse possession in Oregon, a claimant typically must:
- File a quiet title action in the circuit court of the county where the property is located
- Prove possession for the 10-year period required by Or. Rev. Stat. § 105.620
- Demonstrate that possession was actual, open, notorious, exclusive, hostile, and continuous
- Prove an honest belief of ownership that was objectively reasonable and continued throughout the entire 10-year period -- a requirement added when Oregon's adverse possession statute was overhauled in 1989
- Present evidence such as witness testimony, surveys, photographs, fences or monuments, and documentation of improvements
- Meet the "clear and convincing evidence" standard
- Obtain a court judgment granting legal title to the property
Following a successful quiet title action, the claimant should record the judgment with the county recorder's office to establish clear title to the property.
Defending Against Squatters
Oregon property owners can protect against adverse possession claims by:
- Regularly inspecting property boundaries and vacant lots
- Posting "No Trespassing" signs around the property perimeter
- Maintaining accurate surveys and boundary documentation
- Providing written, revocable permission for any allowed use of the property
- Keeping property tax payments current as supporting evidence of ownership
- Taking legal action against unauthorized occupants before the 10-year period runs
- Documenting periodic visits and inspections of vacant or undeveloped land
Any interruption of continuous possession -- a lawsuit, a permission agreement, or the occupant's abandonment -- resets Oregon's 10-year statutory clock.
Removing Squatters
Oregon provides property owners with several options for removing unauthorized occupants:
- Law Enforcement Assistance: unauthorized entry onto or remaining on land or premises can be charged as criminal trespass under ORS §§ 164.245 (second degree) and 164.255 (first degree)
- Expedited Squatter Removal: under HB 3522 (2025, effective January 1, 2026), an owner or landlord may give a true squatter 24 hours' written notice to vacate, then use the same expedited forcible entry and detainer (FED) process available to landlord-tenant evictions if the person does not leave
- Ejectment: for occupants who do not qualify as squatters under HB 3522, owners may still need to file a formal ejectment action in circuit court
- Attend the hearing and, if the court rules for the owner, have law enforcement execute the order to remove the occupants
Oregon law does not permit self-help evictions such as changing locks or shutting off utilities; owners must use the criminal trespass, expedited squatter-removal, or civil ejectment process. HB 3522 does not change Oregon's separate 10-year adverse possession rules.
Notable Oregon Adverse Possession Cases
Hoffman v. Freeman Land and Timber, LLC (1999)
329 Or 554, 994 P2d 106 (1999)
The Oregon Supreme Court held that a rancher's limited, sporadic use of disputed timberland -- even if visible enough to be 'open and notorious' -- was not enough to prove by clear and convincing evidence that the rancher used the land intending to be its true owner. The decision helped define Oregon's 'honest belief' framework: a claimant must show an actual belief of ownership that is objectively reasonable, not merely act consistently with occasional use.
Stiles v. Godsey (2009)
233 Or App 119, 225 P3d 81 (2009)
The Oregon Court of Appeals held that hostile possession can arise either from a claimant's honest but mistaken belief of actual ownership (for example, a mistake about where the true boundary runs) or from an intent to appropriate the property regardless of ownership. On the facts, the court found the plaintiffs had proven a prescriptive easement over a disputed strip but had not met their burden to establish full statutory adverse possession of the same land.
Wiser v. Elliott (2012)
247 Or App 386, 270 P3d 610 (2012)
The Oregon Court of Appeals emphasized that the statutory 'honest belief' requirement for adverse possession is judged objectively: a claimant must show a continuous, objectively reasonable belief of ownership for the entire 10-year period, supported by an objective source such as monuments, fences, surveys, or title documents, rather than a bare subjective or after-the-fact belief.
Mid-Valley Resources, Inc. v. Engelson (2000)
170 Or App 255, 13 P3d 118 (2000)
The Oregon Court of Appeals held that a claimant cannot rely on the 'pure mistake' doctrine to establish hostility if the record owner's own testimony shows she was in conscious doubt about the true boundary line. Without that doctrine's aid, the claimant must instead prove hostile intent to possess the land as an owner by clear and convincing evidence.
Frequently Asked Questions About Oregon Adverse Possession
How long must someone occupy my property in Oregon to claim adverse possession?
Oregon requires 10 years of continuous possession under Or. Rev. Stat. § 105.620. There is no 30-day rule -- short-term occupancy never creates any ownership interest in Oregon.
What is Oregon's "honest belief" requirement for adverse possession?
Since a 1989 statutory overhaul, Oregon requires a claimant to have an honest belief that they actually owned the property, and that belief must be objectively reasonable and continue for the full 10-year period -- for example, supported by a fence, survey, or deed, as discussed in Wiser v. Elliott. This is stricter than simply using the land openly; as Hoffman v. Freeman Land and Timber shows, limited or sporadic use is not enough to prove that belief by clear and convincing evidence.
Does a mistaken belief about a boundary line count as "hostile" possession in Oregon?
It can, under the "pure mistake" doctrine described in Stiles v. Godsey -- but only if the claimant was not in conscious doubt about the true line. Mid-Valley Resources v. Engelson shows that if the record owner's own testimony reveals doubt about the boundary, the claimant cannot rely on pure mistake and must otherwise prove hostile intent by clear and convincing evidence.
Is there a faster way to remove a squatter in Oregon now?
Yes. Starting January 1, 2026, HB 3522 lets owners give a true squatter 24 hours' written notice to leave and then use the same expedited eviction (forcible entry and detainer) process used for tenants, instead of a slower ejectment lawsuit. This law targets unauthorized occupants who are not tenants; it does not change Oregon's separate 10-year adverse possession statute.
Can someone claim adverse possession against government-owned land in Oregon?
No. Land owned by the state of Oregon, its political subdivisions, or the federal government generally cannot be acquired through adverse possession.
Can I legally remove squatters from my property in Oregon myself?
No. Oregon law prohibits self-help evictions such as changing locks or shutting off utilities. Owners must use the criminal trespass process (ORS §§ 164.245, 164.255), the new expedited squatter-removal process under HB 3522, or a formal ejectment action.
Can police remove squatters in Oregon?
Directly, only in the narrowest cases: officers can arrest someone for criminal trespass under ORS 164.255 (first degree, for a dwelling) or ORS 164.245 (second degree) when the entry was clearly unlawful and recent. For everything else, Oregon now channels squatter cases through an expedited civil process rather than police action. Governor Kotek signed HB 3522 on June 20, 2025, effective January 1, 2026, letting an owner give a genuine squatter, someone with no rental agreement, no rent payments, and no other legal right to the property, a 24-hour written notice to vacate that must identify the person as unlawfully present, and then file the same fast-moving forcible entry and detainer (FED) action used in ordinary landlord-tenant evictions if they don't leave. Before HB 3522, owners had to pursue a slower ejectment lawsuit in circuit court, and that ejectment route remains available for occupants who don't meet HB 3522's definition of a squatter, such as a holdover tenant. As in other states, self-help removal like changing locks is illegal, and only law enforcement executing a court order may physically remove an occupant who refuses to leave; HB 3522 also leaves Oregon's separate 10-year adverse possession statute, ORS 105.620, unchanged.
