Adverse possession requires 10 years of continuous unauthorized possession under Wyo. Stat. Ann. § 1-3-103
In Wyoming, a squatter must occupy property continuously for 10 years before they can even attempt to claim legal title through adverse possession, a window set by Wyo. Stat. Ann. § 1-3-103. That decade-long requirement places Wyoming in the mid-range of states nationally: meaningfully more forgiving to owners than five-year states like California, but far shorter than the twenty- and thirty-year periods in parts of the Northeast. For a Wyoming landlord, ten years is long enough that no claim should ever mature if you monitor the property and respond to unauthorized occupants promptly.
The practical takeaway is that time is on your side, but only if you use it. A squatter who is detected and removed within months never gets close to the threshold. The danger is passive ownership, absentee landlords, inherited parcels, and vacant rentals where a trespasser quietly accumulates years. Wyoming law gives you the tools to stop that clock; the rest of this page explains the elements a claimant must prove, how to defeat a claim, and the only lawful way to put someone out.
Adverse possession in Wyoming is not a quick land grab. A claimant carries the burden of proving every element for the full 10 years required under Wyo. Stat. Ann. § 1-3-103, and failing any one of them defeats the claim entirely. The possession must be:
Wyoming's statute does not provide a shortened color-of-title period; the ten-year clock applies whether or not the occupant holds a faulty deed. That uniform window simplifies the analysis for owners: a single decade is the bar, every time.
Because the entire claim depends on continuous possession, any meaningful interruption resets the count to zero. The cleanest interruption is legal action: a single eviction or ejectment filing breaks continuity and restarts the ten-year clock from scratch. You do not have to wait for the period to run before acting, and you should not.
Routine ownership habits prevent claims from ever forming. Inspect vacant and seasonal properties on a schedule, keep parcels posted and secured, and document the dates of every visit. If you find an unauthorized occupant, serve a written demand to vacate and keep a dated copy. Paying property taxes, recording your deed, and granting and revoking any permitted use in writing all reinforce that the occupant's presence is neither exclusive nor hostile. With a ten-year requirement, an attentive Wyoming owner has a wide margin of safety, but the protection only works if the inattention never stretches to a decade.
It is critical to separate two situations. A holdover tenant entered lawfully under a lease or rental agreement and simply stayed past its end; their original permission means they can never satisfy the hostility element of adverse possession. A true squatter never had permission at all. Either way, once someone is occupying a dwelling, Wyoming treats removal as a court matter, not a do-it-yourself one.
Wyoming landlords may not resort to self-help. Changing the locks, removing doors or windows, shutting off electricity, water, or heat, or hauling out an occupant's belongings to force them out is unlawful, and it exposes you to liability even when the occupant has no right to be there. With average rent in Wyoming around $986 a month, the temptation to skip the process and stem the loss is real, but an illegal lockout can cost far more than the rent you are chasing. The correct response is always to route the removal through the courts.
To remove a squatter or holdover lawfully, start with written notice to vacate, then file the appropriate action in court if they refuse to leave. For someone who entered without any agreement, an ejectment or forcible entry and detainer action establishes your superior title and right to possession. For a former tenant, the standard eviction process applies.
After a hearing, if the court rules in your favor, it issues a judgment for possession. Only a sheriff or other authorized officer may then carry out the physical removal under that order, never the landlord personally. This judicial route does double duty: it returns the property to you and, by interrupting the occupant's possession, it conclusively breaks the continuity that any future adverse possession claim would require. Acting through the court early is both the safe path and the one that protects your title for the long run.
There is an important legal distinction between these two types of unauthorized occupants. A holdover tenant is a former leaseholder, someone who once had a valid lease who remains in the unit after that lease has expired without the landlord's consent and without executing a new lease. In Wyoming, holdover tenants are typically treated as month-to-month tenants or as tenants at sufferance depending on whether the landlord continues to accept rent. They must be removed through the formal eviction process with appropriate notice.
A squatter (or trespasser) is someone who entered the property without any prior legal right to do so, they never held a lease with the landlord. Despite having no legal right of occupancy from day one, squatters cannot be physically removed by the landlord without a court order in Wyoming. Changing the locks, removing belongings, or shutting off utilities to force a squatter out constitutes illegal self-help eviction and can expose the landlord to civil liability.
A squatter must occupy the property continuously for 10 years before they can attempt to claim title through adverse possession under Wyo. Stat. Ann. § 1-3-103. They must also prove the possession was hostile, actual, open and notorious, and exclusive for that entire period. Wyoming offers no shortened color-of-title window, so the ten-year requirement applies in every case.
Often not directly. If officers cannot quickly establish that the occupant is a trespasser rather than someone claiming a tenancy or other right to be there, they typically treat it as a civil matter and decline to remove the person. In that situation you must obtain a court order for possession through an eviction or ejectment action; a sheriff then enforces that order. A clear, recent trespass with no claim of tenancy is the scenario most likely to draw a direct police response.
A holdover tenant moved in lawfully under a lease or rental agreement and stayed after it ended, while a squatter never had permission to be there at all. The distinction matters because a holdover's original permission means their occupancy can never be hostile, so they cannot build an adverse possession claim. Both, however, must be removed through the courts, and self-help eviction is illegal against either one.
Use the ten-year window to your advantage by staying engaged. Inspect vacant and seasonal properties regularly, post and secure them, pay your property taxes, and keep your deed recorded. If you find an unauthorized occupant, serve a written demand to vacate and, if needed, file in court. A single eviction or ejectment filing breaks the continuity of possession and resets the ten-year clock to zero, which is why prompt action prevents any claim from ever maturing.
