Do I still need to serve a “party wall notice” on my neighbour if they have signed a “party wall agreement”?
Our party wall agreements contain all of the information required to be included on a party wall notice. You do not therefore need to serve a separate party wall notice if your neighbour has signed the party wall agreement. Unless you have spoken with your neighbour and know that they are willing to sign a party wall agreement you should generally first serve a party wall notice. Your neighbour can still sign a party wall agreement even after notice has been served.
