Neighbors are bound by legal easements imposed by law for their mutual benefit and to prevent conflict. A party wall is a dividing wall presumed to be common between two adjoining owners; there is a legal presumption that dividing walls between buildings, or the dividing walls of gardens or yards, are party walls unless there is a title, sign, or proof to the contrary. Co-owners of a party wall share in its repair and maintenance in proportion to their use or right, and neither may make openings or alterations that impair the other's rights without consent. Other legal easements between neighbors include the easements relating to distances and works for certain constructions and plantings (such as minimum distances for trees near the boundary), the easement of light and view (with rules on windows and required distances), and the easement of drainage of buildings and waters (a lower estate must receive the waters that naturally flow from a higher one, without human intervention). These exist by law, independent of any agreement.
Living next to someone comes with rules the law imposes automatically — about shared walls, distances, windows, and water. These are legal easements between neighbors.
The Party Wall
A party wall is a dividing wall presumed to be common between two adjoining owners. The law presumes that dividing walls between buildings, and the dividing walls of gardens or yards, are party walls — unless there is a title, exterior sign, or proof to the contrary.
Rights and Duties in a Party Wall
- Co-owners share in the repair and maintenance of the party wall in proportion to their use or right;
- Neither owner may make openings or windows in the party wall without the consent of the other; and
- Neither may weaken or impair the wall to the prejudice of the other.
An owner may sometimes increase the height of a party wall at their own expense, subject to the rules and paying for any resulting damage.
Easements Relating to Distances
The law imposes minimum distances for certain works and plantings near a boundary — for example, trees must be planted a required distance from the boundary line, and a neighbor may demand the removal of trees planted too close. Similar rules govern certain constructions and installations.
Easement of Light and View
The easement of light and view governs windows and openings overlooking a neighbor's property:
- Regular (direct-view) windows require a minimum distance from the boundary; and
- Restricted openings (for light only) are allowed under conditions, but do not grant a right of full view.
Easement of Drainage
The easement of drainage of waters provides that a lower estate must receive the waters that naturally flow from a higher estate, without human intervention. The lower owner cannot obstruct this natural flow, and the higher owner cannot artificially increase the burden. There are also rules on the drainage of roofs, so that rainwater does not fall onto a neighbor's land.
These Exist by Law
Crucially, these are legal easements — they exist by operation of law, for the mutual benefit of neighbors, independent of any agreement. Neighbors do not need a contract for them to apply.
Practical Takeaways
- A party wall is presumed common — owners share maintenance and cannot make openings or weaken it without consent;
- The law imposes distance rules for trees and works, and an easement of light and view for windows;
- A lower estate must receive naturally flowing water from a higher one — these legal easements apply automatically.
