N244 form for enforcing court direction

[DavidJB]

Hi. I'm going to Small Claims in a dispute with a builder and the court ordered a jointly instructed surveyor's report of the partially completed building works. The builder knows that my case will fail without this and he is not cooperating with giving the joint instruction, knowing that I can't do it on my own. I have explained this to the court and asked for guidance and they say I can use an N244 form to ask the court to enforce the order, but I don't know what I write on it. Just "please enforce it" or do I need to tell them what I am asking them to do to enforce it, in which case I don't know what to ask for...
Thanks for any help!
