I own a semidetached cottage and I have allowed the adjoining property to be connected to my cesspool for more than 20 years. They have never contributed towards emptying or maintenance. Since their property is now up for sale and I do not wish to share with any new owner, am I within my rights to disconnect at this stage?
Yes. The owners of the neighbouring cottage will have gained no rights over your property by using your facilities with your permission. However I suggest you give your neighbours advance notice of your intentions. A property with no sewage outlet will be very difficult to sell, and the consequences of a peremptory disconnection could be drastic.
