Squatters Rights in Missouri: 10-Year Adverse Possession Law
Missouri requires 10 years of hostile, open and notorious, actual, exclusive, and continuous possession. A 2024 law created a clear legal mechanism — separate from the state's 'unlawful detainer' statutes for tenants — for owners to remove unauthorized occupants.

How Adverse Possession Works in Missouri
To claim ownership of property through adverse possession in Missouri, a claimant must possess the land for 10 years while meeting the legal requirements established under state law.

Recent Law Changes in Missouri
2024: New provisions (Mo. Rev. Stat. §§ 534.602, 534.604), enacted August 2024, broadened the definition of first-degree trespass to cover unauthorized entry into and refusal to vacate vacant properties, while requiring owners to affirm they never leased the property to the occupant (false affidavits carry criminal and civil penalties). This is a removal-process change and does not alter the 10-year adverse possession period.
Missouri Adverse Possession Procedures
Making an Adverse Possession Claim
To establish adverse possession in Missouri, a claimant must satisfy the 10-year statutory period under Mo. Rev. Stat. § 516.010 and prove all five elements in a quiet title action.
- File a quiet title action in the circuit court for the county where the property is located
- Prove possession was hostile and under claim of right, actual, open and notorious, exclusive, and continuous for the full 10 years
- Show the possession was in defiance of the record owner's rights, not merely permissive use later reinterpreted as adverse
- Present supporting evidence such as tax records, surveys, photographs of improvements, and witness testimony
- Obtain a court judgment and record it with the county recorder of deeds to establish clear title
Missouri's 10-year period is on the shorter end nationally; unlike some states, there is no separate shortened period tied to 'color of title.'
Defending Against Squatters
Missouri property owners can take practical steps to prevent an adverse possession claim from maturing.
- Regularly inspect vacant, rural, or investment property
- Post 'No Trespassing' signs at property boundaries
- Maintain current surveys and boundary documentation
- Grant explicit written permission for any use you allow -- permissive use cannot become hostile unless the claimant clearly and openly asserts a contrary right
- Keep property tax payments current
- Act promptly against unauthorized occupants well before the 10-year period could run
Any interruption of continuous possession, including successful removal of the occupant, resets Missouri's 10-year clock.
Removing Squatters
Missouri added a fast, ex parte removal process for unlawful occupants in 2024 under Mo. Rev. Stat. §§ 534.602 and 534.604, alongside its existing eviction and trespass laws.
- File a verified petition in the circuit court for the county where the property is located, showing the occupant entered without permission, the property was not leased to anyone in the prior three months, and the occupant is not a current or former tenant
- If the court finds good cause, it can issue an ex parte order for the occupant's immediate removal, effective right away
- The court holds a follow-up hearing, typically within 48 hours, to confirm the order
- Give the order to law enforcement, who can arrest anyone who violates it -- a class A misdemeanor -- regardless of whether the violation occurs in the officer's presence
- For occupants who may qualify as tenants, use Missouri's standard unlawful detainer/eviction process instead
Missouri law still prohibits 'self-help' evictions such as changing locks or shutting off utilities against anyone with a colorable tenancy claim; the expedited §534.602 process applies specifically to unlawful occupants who were never tenants.
Notable Missouri Adverse Possession Cases
Walker v. Walker (1974)
509 S.W.2d 102 (Mo. banc 1974)
The Missouri Supreme Court held that a claimant's possession must be hostile and under a claim of right, meaning it is exercised in defiance of, not in subordination to, the record owner's rights. This case is a foundational statement of Missouri's five-element adverse possession test: hostile, actual, open and notorious, exclusive, and continuous possession for ten years.
Teson v. Vasquez (1977)
561 S.W.2d 119 (Mo. App. 1977)
The Missouri Court of Appeals, in a large dispute over river-bottom farmland in St. Louis County, held that hostile possession must be 'antagonistic to the claims of all others' -- the claimant must occupy the land intending to hold it as their own rather than in subservience to someone else's superior claim, even against a party holding a recorded quitclaim deed.
Shanks v. Honse (2012)
364 S.W.3d 809 (Mo. Ct. App. 2012)
The Missouri Court of Appeals for the Southern District applied Missouri's adverse possession elements to a boundary dispute, reaffirming that possession originating with the true owner's permission remains permissive -- and cannot support adverse possession -- unless and until the claimant makes a clear, open assertion of a hostile right that is communicated to the owner.
Frequently Asked Questions About Missouri Adverse Possession
How long must someone occupy my property in Missouri to claim adverse possession?
Missouri requires 10 continuous years of possession that is hostile, actual, open and notorious, exclusive, and under a claim of right, per Mo. Rev. Stat. § 516.010. The '30-day squatter's rights' claim circulating online is a myth.
What does 'hostile' possession mean in Missouri?
Under Walker v. Walker (1974) and Teson v. Vasquez (1977), hostile possession means occupying the land in defiance of the record owner's rights and antagonistic to any other claims -- not merely using it with the owner's permission. Possession that starts permissively stays permissive unless the claimant clearly and openly asserts a contrary right that the owner becomes aware of.
How quickly can a property owner remove a squatter in Missouri now?
Very quickly for occupants who were never tenants. Since 2024, Mo. Rev. Stat. § 534.602 lets an owner file a verified petition and get an ex parte court order for the occupant's immediate removal, with a follow-up hearing typically within 48 hours. Violating the order is a class A misdemeanor under § 534.604.
Can I legally remove squatters from my property in Missouri?
Yes, but through legal channels. For someone who was never a tenant, Missouri's expedited unlawful-occupant process (§ 534.602) can produce a removal order within days. For anyone claiming tenant status, use the standard unlawful detainer process. 'Self-help' evictions -- changing locks, shutting off utilities -- remain illegal in Missouri.
Can someone claim adverse possession against government-owned land in Missouri?
No. Missouri law exempts land owned by the state, counties, municipalities, and the federal government from adverse possession claims.
Can trespassers gain rights to my property after 30 days in Missouri?
No. This is a nationwide myth with no basis in Missouri law. Adverse possession requires 10 years of continuous, hostile, open, notorious, and exclusive possession -- occupancy of a few weeks or months creates no ownership interest.
Can police remove squatters in Missouri?
For genuine trespassers, yes, directly: Missouri's first-degree trespass statute, RSMo § 569.140, lets officers act against someone who knowingly entered or remains unlawfully with no claim of right. Missouri also confirmed and enacted a faster civil-criminal hybrid tool in 2024 -- Governor Mike Parson signed HB 2062 on July 9, 2024, creating RSMo §§ 534.602 and 534.604, which let an owner file a verified petition showing the occupant entered without permission, the property wasn't leased to anyone in the prior three months, and the occupant isn't a current or former tenant. A judge can issue an ex parte removal order right away, followed by a confirming hearing typically within 48 hours, and violating that order is a class A misdemeanor police can enforce with arrest. Anyone who may qualify as a current or former tenant falls outside this fast-track process and must instead be removed through Missouri's standard unlawful detainer/eviction procedure in circuit court.
