First of all make sure you print with Page Numbers.
It might be an idea to initial each page.
Obviously sign at the end in your normal signature ... i.e. in my case it would just be "Veronica" ... since that's a signature I often use. I discussed signatures here: viewtopic.php?f=6&t=23
As far as the witnesses go, the same applies ... whatever they are most comfortable with.
As I said in that topic, your signature is only your personal 'mark' ... such as you could reproduce it at will. If anyone argues at any variance (they wouldn't) then a Handwriting Expert can tell that it was you ... and that's all that matters.
I think I'll just send A PHOTOCOPY of mine to the Home Office, and let them sort it out first of all. If they think the DVLA, etc, need to know, let them sort it out. It says "Furthermore, I claim the law of agent and principal applies and that service upon one is service upon both."
... which means it's up to them to tell anyone else.
I WON'T fill in the Place of Claim until all objections are resolved. What I will probably do about objections I can't resolve is add a Schedule B which lists exceptions. IT MIGHT BE A GOOD IDEA TO ALLOW FOR THAT TO START WITH. In other words start off with a blank Schedule B (in my case). I don't know how others are doing this. I've numbered everything in preparation. See here: http://www.fmotl.com/NoticeOfUnderstanding.htm
Schedule B could contain a list of updates, or actions taken on the original.
When finally resolved, I'll add the Place of Claim. IN THE MEANTIME THE ORIGINAL WILL NOT BE LODGED WITH MYSELF, OR ANY OF MY 3 WITNESSES. In other words to place of the original will not be disclosed. (You never know!)
