Which easement is used for the construction of common party walls between properties?

The correct choice is a Support Easement. This type of easement allows one property owner to support, or maintain, a structure that physically extends over or under another person's property. In the context of a common party wall, a Support Easement ensures that both property owners have legal rights related to the shared wall, which serves as both a structural element and a boundary between the two properties. This easement ensures stability and structural integrity, as both parties are dependent on the wall for their respective buildings.

Given this context, a Joint Use Easement would typically involve shared access or use of space rather than the specific structural support of a wall. Similarly, a Utility Easement is designated for utility providers to install and maintain their infrastructure, such as water lines or electricity, while an Access Easement focuses on providing a pathway for entry to a property. None of these options align with the structural focus of a Support Easement related to party walls.
