What is the term for a wall used jointly by two parties under an easement agreement?

The correct term for a wall that is used jointly by two parties under an easement agreement is a party wall. A party wall is specifically designed to serve as a shared boundary between two properties, allowing for mutual use and benefits. It is typically built on the property line and may be used by both property owners for support or other structural purposes.

This term is significant in property law because it outlines the rights and responsibilities of each party concerning the maintenance and use of the wall. The legal framework governing party walls can vary, and easement agreements typically detail how costs and upkeep responsibilities are to be managed between the parties involved.

Other terms, while they may be used in construction, do not accurately describe this joint use and legal arrangement. For instance, a boundary wall generally refers to any wall that delineates the separation between two properties but does not imply shared ownership or use. A common wall suggests a similar purpose as a party wall, but it is less frequently used in legal contexts and can lead to confusion. A retaining wall, on the other hand, serves to hold back soil or stabilize elevation changes and is not considered a shared structure between two properties.
