Let me answer this as far as I am able.
I cannot comment on the validity of the appeal.
You need to remember that the Party Wall Act has no teeth. There is no penalty for non-compliance.
The idea of the Party wall Award (why it’s called an award I have no idea because it’s an agreement) is that it is an “agreement” unless there has been an argument and the whole matter has been determined which is then subject to an appeal which is where you appear to be at now.
You cannot beat the neighbour with a stick and if they decide to go ahead regardless, your only remedy is an emergency application to court for an injunction to stop the work going ahead under threat of arrest.
You need to tell the contractors that if they stop this work you will make an immediate application to court for an injunction against them in the neighbour and you will ask the court to award costs against them.
I would prepare the proceedings now ready to get them to the court.
Applying for a prohibitory (preventing) or mandatory (compelling) injunction is relatively straightforward. Just work it through a bit at a time.
There is a specific court order form N 16 A injunction application form which is here: https://www.gov.uk/government/publications/form-n16a-application-for-injunction-general-form
And you will also need court form N1 which is here
I have no idea why some require the extra N1 form because in my opinion it doesn’t add anything to the process but if they want it, let them have it. Alternatively you could use N208, which is virtually the same as N1. The difference is that N1 is part 7 of the Civil Procedure Rules and N208 as part 8 of the civil procedure rules.
If you want to know what the difference between part 7 and part 8 is, join the queue. Part 7 is appropriate if there are lot of evidential issues but how you decide that, the majority of solicitors don't even know.
So you can use one or the other.
The court fee is GBP308
You are going to need also a witness statement in this format
Please note that the Statement of Truth at the end of a witness statement has changed. It changed quietly on 6 of April 2020.
Here is the form of witness statement on the government website which at the time of putting the link together, still had the old Statement of Truth.
Here is the new wording: https://parissmith.co.uk/blog/guidance-signing-statement-of-truth/
it is referred to in box 6 of the N16
if there is some urgency with this you can make an emergency application and the next 48-hour is. You would need to attach a Certificate of Urgency (a letter headed as such) saying why this is urgent.
Incidentally, it would be a good idea to attach screenshots or documents, and in the witness statement you would say “a copy (or a screenshot) of the XXX is attached marked Exhibit A”. You then write Exhibit A (and so on and so forth) at the top of the exhibit.
You also need to ask the court to award costs against the other person, in your favour and in that respect you need a timesheet of everything that you have spent timewise and moneywise, including this advice, at GBP19 per hour.
The most important document is the witness statement. There is a days work in putting this together at least so start now.
It would take a solicitor half a day to get it into good shape.
