Boundary Markings | How do I know who is responsible?
As a homeowner, it is important to know which boundaries that surround your property you are responsible for.
The most common marking on deed plans that relates to boundaries are 'T' marks. An entry referring to a 'T' mark is normally a statement concerning the ownership of a boundary structure or the liability to maintain and repair it.
A 'T' mark on your side of the boundary indicates that you own the fence and are responsible for its upkeep. If 'T' marks appear on both sides forming an 'H' shape, it signifies joint ownership and shared responsibility with your neighbour.
If your title deeds have no 'T' marks or other references to boundaries, it is generally considered that the boundary is a shared boundary, meaning the property owner and their neighbour are jointly responsible for its maintenance and repair. 'T' marks, when present, typically indicate which side of the boundary structure (like a fence) is responsible for repairs.
When looking at your Land Registry title plan you may not see the 'T' marks and therefore it is important to refer back to your original deeds.
