I have some legal documents which must be witnessed by a JP. I don't personally know anyone who is a JP and I'm unsure how to go about finding one! Does anyone know, please?

Also, how much does a JP charge? I assume they don't do it out of the kindness of their hearts and also need to cover the cost of some sort of registration?

Thank you!

(Sorry, Mods, struggled to figure out where to put this one!)
