Squatters Rights in Idaho: 20-Year Adverse Possession Law
Idaho requires 20 years of possession, reduced to 5 years for claimants with color of title who pay all property taxes for that period. A 2025 law gave sheriffs new removal authority and created criminal penalties for fraudulent lease or deed documents.

The Path to Adverse Possession in Idaho
A visual summary of what a claimant must complete, start to finish.
How Adverse Possession Works in Idaho
To claim ownership of property through adverse possession in Idaho, a claimant must possess the land for 20 years while meeting the legal requirements established under state law. A shorter 5-year track is available for claimants who pay property taxes and, where required, hold color of title.
Legal Basis and Statutory Period
Idaho’s adverse possession law is codified under Idaho Code § 5-210; HB 321 of 2025. The standard statutory period is 20 years of continuous, open, and hostile possession.
Property Tax Requirements
A shorter 5-year period applies to claimants who hold color of title and pay all property taxes on the land for that period.
Color of Title Rules
Color of title is not required for the standard 20-year claim, but is required (with tax payment) for the shorter 5-year track.
Key Legal Requirements
- Actual possession
- Open and notorious possession
- Hostile possession
- Exclusive possession
- Continuous possession for 20 years (5 years with color of title and tax payment)

Recent Law Changes in Idaho
2025: House Bill 321, passed the Idaho Legislature in March 2025, gives sheriffs authority to remove an unauthorized occupant and creates new criminal penalties — a misdemeanor for knowingly presenting a false document purporting to be a valid lease, deed, or other instrument conveying property rights, or for listing property for sale without legal title. This is a removal-process and criminal-penalty change and does not alter the 5/20-year adverse possession periods.
Idaho Adverse Possession Procedures
Making an Adverse Possession Claim
To establish adverse possession in Idaho, a claimant typically must:
- File a quiet title action in the district court of the county where the property is located
- Provide clear and convincing evidence of 20 continuous years of possession under Idaho Code § 5-210
- Show that the land was protected by a substantial enclosure, or was usually cultivated or improved, in a manner appropriate to the character of the property
- Prove that all property taxes on the claimed land were paid throughout the entire 20-year period
- Demonstrate that possession was actual, open, notorious, exclusive, hostile, and continuous
- Present evidence such as witness testimony, tax receipts, photographs, surveys, and documentation of improvements
- Obtain a court judgment granting legal title to the property
Idaho requires 20 years of possession, one of the longer periods in the country, since a 2006 amendment quadrupled the prior 5-year period. Following a successful quiet title action, record the judgment with the county recorder to establish clear title. HB 321, enacted in 2025, further tightened protections for property owners against unauthorized occupants.
Defending Against Squatters
Idaho property owners can protect against adverse possession claims by:
- Regularly inspecting property boundaries
- Posting "No Trespassing" signs around the property perimeter
- Maintaining accurate property surveys and documentation
- Providing written permission for any allowed use of the property
- Keeping property tax payments current and disputing any taxes an occupant attempts to pay on the property
- Taking legal action against unauthorized users before the statutory period expires
- Documenting property visits and inspections
- Considering a property management service for vacant properties
Because Idaho requires the claimant to have paid all property taxes on the land for the full 20 years, staying current on your own tax payments is one of the strongest defenses against an adverse possession claim. Any action that interrupts continuous possession also restarts the statutory period.
Removing Squatters
Idaho provides property owners with several options for removing unauthorized occupants:
- Law enforcement assistance: for clear cases of trespassing, request assistance from law enforcement under Idaho's criminal trespass laws (Idaho Code §§ 18-7008, 18-7011)
- Unlawful detainer action: file a complaint with the magistrate division of the district court in the county where the property is located
- Attend the hearing, typically scheduled promptly
- If successful, obtain a writ of restitution
- Have the sheriff execute the writ to remove the occupants
Idaho law prohibits "self-help" evictions such as changing locks, removing doors, or shutting off utilities. Property owners must follow legal procedures to remove occupants or risk civil and criminal liability. HB 321 (2025) streamlined some of these removal procedures for clear cases of unauthorized occupancy.
Notable Idaho Adverse Possession Cases
Kennedy v. Schneider (2011)
151 Idaho 440, 259 P.3d 586 (2011)
A couple who had asserted adverse possession over three parcels under a written claim of title won a quiet title decree at the district court, which found they had proven their claim by clear and satisfactory evidence. The Idaho Supreme Court vacated that decree on appeal, holding the record lacked substantial, competent evidence to support the trial court's findings and remanding the case, underscoring how demanding Idaho's clear-and-convincing evidentiary standard is for adverse possession claimants.
Fischer v. Croston (2018)
163 Idaho 331, 413 P.3d 731 (2018)
Neighbors in Bonneville County had treated an old fence line as their shared boundary for decades until a new survey showed it didn't match the platted property line, prompting one side to tear down the fence and build a new one on the surveyed line. The Idaho Supreme Court affirmed summary judgment holding that the old fence line was a valid boundary by agreement that controlled over the platted description, but rejected the other neighbor's attempt to establish a new boundary-by-agreement claim where no actual boundary dispute existed at the time the new fence went up.
Fickenwirth v. Lanning (2023)
172 Idaho 199, 538 P.3d 370 (2023)
Adjoining owners disputed a strip of land after one replaced a decorative split-rail fence near a shared gravel driveway with a new fence set slightly differently, and the driveway owners sued claiming the strip by adverse possession or boundary by agreement. The Idaho Supreme Court affirmed that the driveway owners failed to prove adverse possession or boundary by agreement at the old fence's location, while upholding the trial court's finding that a boundary by agreement had been established at the new fence line instead.
Owen v. Smith (2021)
168 Idaho 633, 485 P.3d 129 (2021)
New neighbors built a fence along the boundary shown in a survey obtained during their purchase, but the adjoining owners disputed that line and sued for trespass and loss of use of the disputed strip. The Idaho Supreme Court affirmed summary judgment for the buyers, holding they were bona fide purchasers with a superior claim to the land described in their deed and upholding a permanent easement for a buried irrigation pipeline crossing the property.
Frequently Asked Questions About Idaho Adverse Possession
How long must someone occupy my property in Idaho to claim adverse possession?
Idaho requires 20 continuous years of possession under Idaho Code § 5-210, with the claimant paying all property taxes on the land for that entire period. This is one of the strictest adverse possession standards in the country. Idaho's period was only 5 years until a 2006 amendment quadrupled it to 20 years. The commonly repeated "30-day squatter's rights" claim is a myth.
Does Idaho require payment of property taxes for adverse possession?
Yes. Unlike many states where tax payment is just supporting evidence, Idaho Code § 5-210 makes payment of all property taxes on the claimed land throughout the full 20-year period a required element of the claim, not merely an optional one.
What kind of use satisfies Idaho's possession requirement?
Idaho law requires that the land be protected by a substantial enclosure, such as a fence, or usually cultivated or improved in a way consistent with its character. Idaho courts have treated a long-maintained fence line as establishing a boundary by agreement, as in Fischer v. Croston (2018) and Fickenwirth v. Lanning (2023), while claimants who cannot show enclosure, cultivation, or full tax payment for the entire period typically fail, as happened in Kennedy v. Schneider (2011).
Can I legally remove squatters from my property in Idaho?
Yes, but only through legal procedures. For clear trespassing, you can request law enforcement assistance under Idaho's criminal trespass statutes. Otherwise, an unlawful detainer action must be filed in the magistrate division of the district court. "Self-help" methods like changing locks or cutting off utilities are illegal in Idaho and can expose the owner to liability.
Can someone claim adverse possession against government-owned land in Idaho?
No. Idaho law exempts land owned by the state, federal government, counties, cities, and other public entities from adverse possession, and certain infrastructure such as irrigation district easements and rights-of-way is separately protected from adverse possession under Idaho Code § 42-1208. This matters in Idaho, where a large share of land is federally or state owned.
Can trespassers gain rights to my property after 30 days in Idaho?
No. This is a common misconception. Idaho requires 20 years of continuous, open, notorious, exclusive, and hostile possession, plus payment of all property taxes on the land, to establish adverse possession. Short-term occupancy of any length does not create ownership rights.
Does Idaho allow police-assisted squatter removal?
Only through a court-ordered process, and Idaho recently made that process much faster. Officers can arrest a person on the spot for criminal trespass under Idaho Code §§ 18-7008 and 18-7011 if there's no claim of a landlord-tenant relationship or prior permission, but they cannot simply remove someone from a home on a bare phone call — a court order is still required to put the owner back in possession. As of July 1, 2025, House Bill 321 created Idaho Code § 6-310A, a new expedited alternative to the standard unlawful detainer action (Idaho Code § 6-303): for residential property where the occupant never had a rental agreement with the owner, the court must hold a hearing within 72 hours of the complaint being filed, and if the owner prevails, the sheriff enforces the order removing the occupant — far faster than a standard eviction case. HB 321 also made it a crime to submit false statements to obtain removal under this process, and anyone with a colorable claim of tenancy (a lease, rent payments, or a prior landlord-tenant relationship) falls outside § 6-310A and must go through ordinary unlawful detainer proceedings instead.
