Common Examples

Fenced Backyard Encroachment
Pinecrest Builders erected fences six feet beyond the true boundary onto Summit Development land based on a mistaken plat. Successive townhome buyers mowed, gardened, and maintained patios in the strips. The permanent fences and visible improvements remained in place year-round. Summit later demanded removal after more than ten years.
Seasonal Lakefront Beach Use
Gilbert rented his cabin and included a disputed beach strip in each lease under a good-faith boundary belief. Successive tenants used the beach each summer for recreation while the fence line stayed visible. Victoria sued to quiet title after decades of summer use.

Laboratory Security Fencing
Peak Drug built laboratory buildings and security fencing on Carol's land under an oral arrangement. The fenced compound operated continuously and visibly for decades. Christopher sued after Carol died.

Common questions
Frequently Asked
4
What makes use open and notorious in adverse possession?+
The use must be visible and apparent so that a reasonable owner visiting the premises would readily notice the invasion of rights. Fences, structures, and regular activity that signal exclusive control satisfy the element.
Supporting sources
Does seasonal use satisfy open and notorious for lakefront property?+
Yes when the seasonal pattern matches how an average owner would use that type of land. Summer recreation on a beach with a visible fence line provides the required notice.
Supporting sources
Can tacking occur when each possessor acts under a mistaken boundary belief?+
Yes. Successive owners who each believe they own the strip may add their periods together to meet the statutory requirement. The open and notorious character of the use continues across the transfers.
Supporting sources
Does actual knowledge by the true owner satisfy the open and notorious element?+
Yes. When the owner sees the visible improvements and ongoing activity, the element is met even without formal notice.
