As the neighbouring property owner you should encourage your neighbour who is about to carry out notifiable works under the Party Wall ACT to issue you with the relevant notice/s.
Once you have received the relevant notice/s you will initially have 14 days to respond.
Under the Party Wall ACT you are able to agree to the works, agree to the appointment of an Agreed Surveyor acting for you and your neighbour or appoint your own surveyor (typically at the cost of your neighbour).
If you have received a notice from your neighbour please do contact us so we can discuss your options in more detail.
