Thank you for your question. I am happy to assist you.
To acquire property in Kansas by adverse possession, the possessor would need to show the court that the use of the land has been open, continuous, exclusive and hostile for the statutory period in order to quiet the title of the land in his favor.
In KN the statutory period is 15 years. Kansas Code 60-503.
Here is the statute for your convenience:
60-503. Adverse possession.
No action shall be maintained against any person for the recovery of real property
who has been in open, exclusive and continuous possession of such real property, either under a claim knowingly adverse or under a belief of ownership, for a period of fifteen (15) years. This section shall not apply to any action commenced within one (1) year after the effective date of this act.
History: L. 1963, ch. 303, 60-503; Jan. 1, 1964.
The estate or heirs will now want to file an action to evict the man from the property. This will prevent him from acquiring title by adverse possession.
You will require the services of a local attorney. If that is not possible, you can purchase the forms to file at: http://www.nupplegal.com/kseviction.html
I hope that the information which I provided was helpful to you.
Best wishes for a successful outcome. If you have additional questions, please do not hesitate to submit them to me directly.
