If you use the wiki service they will do all the forms for you, the form that goes with the
Consent Order is called statement of information for consent (D81) its quick and easy to complete, basically its assets and income for you both, this is needed so the judge considering the order can make sure the agreement falls within mca s25.
If your ex decides not to use a solicitor the judge may question the him/her to make sure the understand what they are agreeing too, you will be fine as you will have the wiki solicitor, the wiki peeps will explain how it all works before you pay the dosh, or you can call the wiki helpline and one of the guys will talk you through it.
Don`t worry too much about this, my own order was questioned by the judge, my ex and i went to court and the hearing lasted about seven minutes, the order was sealed and it was over.
Your ex lives a long way off so in his/her case they would ask to talk to the judge on the phone rather than appear in court, this is becoming the norm these days even with Directions hearings, one of the better changes made recently.
