What is defined as the open, continuous, exclusive, and notorious possession of another's land that may lead to acquiring title?

The concept described is known as adverse possession. Adverse possession allows an individual to claim legal title to land under certain conditions when they have openly and continuously occupied someone else's property without permission for a specific period, which varies by jurisdiction. This possession must be exclusive, meaning that the individual is not sharing the use of the land with the true owner or the public, and it must be notorious, as it must be apparent and visible enough that the true owner is presumed to have knowledge of it.

This legal principle is based on the idea that the true owner's failure to act on their property rights over time can lead to the abandonment of those rights. As a result, after meeting all the specific requirements, the person in possession may ultimately be able to transfer legal title to themselves, securing ownership of the property despite not originally having legal title.

The other options do not fit this definition. Conditions refer to specific requirements in agreements or leases, easements by necessity relate to the right to use another's property when a piece of land is landlocked, and a covenant generally refers to a formal agreement or promise in a deed, which does not pertain to possession or acquiring title through use.
