Section 15 of the act describes methods for serving notices, awards etc required under the act. Party Wall Surveyors were trained to pedantically follow the methods of serving and did so – this is probably due to their lack of understanding of the law and how to read and interpret statute. They misinterpreted the English language!
However the most recent case law Night v Goulandris on the methods of serving notices, award etc allows any method as long as the server can guarantee the document has been served and it is recommended reading for all aspirant and serving Party Wall Surveyors and will enlighten surveyors on English Grammar and pedantry.
The methods of service specified in the Act are not exhaustive, the ‘may’ in s15 being permissive, Knight v Goulandris  EWCA Civ 237, but email (or any other form of electronic) service is now covered by the 2016 Order and requires the express agreement of the recipient. In the Knight case the Court of Appeal noted that at common law ‘service’ requires ‘receipt’, (putting aside the special rules about post), but the Court did not expressly consider whether the arrival of an email in the recipient’s inbox is sufficient to constitute receipt or whether there is no receipt until the email is accessed.
