What legal concept involves a charge on one estate for the benefit of another?

The legal concept that involves a charge on one estate for the benefit of another is an easement appurtenant. This type of easement is a property right that allows one parcel of land to benefit from the use of another parcel. The easement becomes part of the property and transfers with the land, meaning that when the property is sold, the new owner also receives the benefit of the easement.

An easement appurtenant typically involves two properties: the dominant estate, which benefits from the easement, and the servient estate, which is burdened by it. For example, if one property owner has the right to cross a neighbor's land to access a road, the neighbor's land is the servient estate, while the property that needs access is the dominant estate.

This distinguishes it from other options, such as encumbrances, which refer more broadly to any claim against property that may diminish its value, or a charging order, which is related to a legal claim against a business interest rather than real estate. Therefore, easement appurtenant is the appropriate concept that specifically involves a charge on one estate for the benefit of another.
