A common wall, which also goes by the name "party wall", is a type of wall that is shared by two different properties. This wall can be found in townhouses, apartments or condominiums. Instead of referring to it as a common wall, it can also be called a dividing wall, shared wall, adjacent wall, or boundary wall. A common wall can often cause disputes between neighbors, which is why it is important for property owners to understand their rights and obligations when it comes to the use and maintenance of the wall. Whether it's called a common wall or any of its synonyms, it is important to always ensure that the wall is in good condition to prevent any potential legal issues.
