An easement is the right of a party to use land that does not belong to them. There are two parties to an easement:
Easements are registered if they are shown on the plan, together with their ownership. Sewerage easements are sometimes not shown on title plans, and are thus unregistered.
An unused registered easement can be removed from a title by the servient party applying to the Registrar of Titles. Alternatively, a dominant party can agree to their easement being removed from the servient party’s title as the result of an agreement between the parties, which may involve consideration.
