Final answer:
An easement acquired by consistent use over time is known as an easement by prescription, which is established after using the property in a certain way for a legally defined period, without the owner's permission.
Step-by-step explanation:
An easement acquired by constant use is known as an easement by prescription. This occurs when someone has used another's property openly, continuously, and without the owner's explicit permission for a period that is defined by state law, which often ranges from 5 to 20 years. To claim an easement by prescription, the use must be adverse, which means it occurs without the approval or against the will of the landowner.
Easements are important non-government restrictions that complement restrictive covenants in controlling land use. Both private entities and individuals use easements to allow for the preservation of open space and conservation, as well as for practical access to property that would otherwise be difficult or impossible.
