A Party Wall Agreement is a legal arrangement between two property owners who share a common wall, typically in townhouses or semi-detached home. This agreement outlines the responsibilities, rights, and obligations of each party in relation to the shared wall, including maintenance, repairs, and any potential alterations. It ensures that both owners are aware of their duties, helps prevent disputes, and provides a clear framework for handling issues related to the wall, whether it’s structural damage, renovation, or access for repairs.
