yes, it sounds as though the court are suggesting that you ask for a
direction that service has been effected.
at 3 you are asking
the court to make a direction that service is deemed to have taken
place.
that would then allow you to comtinue with the
divorce.
the 'why' is that you have received a letter from your ex
(attach a copy) stating he has received the
petition.
I think you should be fine just
giving fuller details in box 10, without needing an additional
affidavit. Reference the letter and confirm that you
can identify thesiganture as being that of your husband
