A quality of possession required for adverse possession under which the claimant's use of the land is sufficiently apparent and unconcealed that a diligent owner would have notice of the intrusion.

Fenced Backyard Encroachment
Pinecrest Builders erected a fence six feet beyond the true boundary onto Summit Development's vacant parcel and sold the townhomes to Lopez, Chen, and Rivera. Each buyer mowed, gardened, and used patios inside the fenced strips for more than ten years. Summit later demanded removal of the fences, but the visible fencing and regular backyard activities supplied the open and notorious element that allowed tacking and satisfied the statutory period.
Seasonal Lakefront Beach Use
Gilbert rented his cabin to successive tenants who used a disputed beach strip on Victoria's lot each summer for recreation. The tenants placed chairs and equipment openly during the season and left the area fenced year-round. Victoria sued after decades, but the consistent seasonal pattern visible to any observer met the open and notorious requirement and permitted tacking of the good-faith periods.

Hedgerow and Shed on Orchard Strip
The Johnson Partnership expanded a hedgerow and irrigation ditch onto Beth's strip, planted crops, grazed cattle, and built a tool shed that remained in plain view from the orchard line for decades. Beth purchased the orchard five years before suit but raised no objection until a new survey. The cultivated strip and structures were sufficiently visible to satisfy the open and notorious element and support tacking across generations.
Freight Yard Improvements
Silver Logistics paved sections of Flora's rail yard, stored containers, posted signs claiming exclusive ownership, and conducted daily loading visible from the public road while paying the listed taxes. Flora took no steps to monitor the parcel during the entire period. The prominent signs and continuous operations were open enough to put any reasonable owner on notice of the claim.
Mountaintop Tower Installation
Frontier Fiber erected a perimeter fence around Arthur's summit, posted signs, and operated transmission towers continuously for fifteen years. The fenced compound and active equipment were visible to anyone approaching the site. Arthur accepted annual fees without objection, yet the physical barriers and ongoing operations met the open and notorious standard against the present estate.
Mistaken Boundary Cabin Occupancy
Howard's predecessors occupied a cabin on the Kunto parcel under a good-faith belief it lay within their deeded tract and used the land seasonally in a manner typical for waterfront property. The cabin and regular maintenance were plainly observable from the true boundary. Successive owners continued the same visible pattern, satisfying the open and notorious element and allowing tacking to complete the statutory period.
Common questions
Frequently Asked
4
What makes possession open and notorious rather than secret?+
The use must be visible to a common observer so that the record owner receives actual or constructive notice. Fences, structures, cultivation, and regular activity that would alert a diligent owner satisfy the element, while hidden or concealed acts do not.
Supporting sources
Does seasonal or intermittent use defeat the open and notorious requirement?+
No. Seasonal use consistent with the nature of the property satisfies continuity and can still be open and notorious when accompanied by visible improvements such as fences or structures that remain year-round.
Supporting sources
Can mistaken boundary possession still be open and notorious?+
Yes. Good-faith occupation under a mistaken boundary that produces visible fences, plantings, or structures provides the required notice even though the possessor does not intend to oust the true owner.
Supporting sources
Does the true owner's actual knowledge of the use satisfy the open and notorious element?+
Yes. Actual knowledge by the owner satisfies the requirement because the purpose of the element is to ensure the owner has notice of the adverse claim.
