I sent him a draft petition from my lawyer so he had a chance to give input on it. My lawyer said that is very often done these days to keep things amicable. He wanted a few changes made and I agreed. Your ex could have done that as it does not really matter what the facts set out in it say. Now he has gone ahead it's not likely anyone will ever read it so just let it lie and negotiate a good financial settlement to avoid wasted costs on court hearings etc. We had no court hearings. Much better just to agree things.
Yes, they can go ahead if you don't respond. What will happen is your D's solicitors will arrange for you to be served personally with the petition. They will get another copy and get a process server to physically hand it to you, at home or at work. Not nice. Your other option would be if you really are feeling upset about his allegations is to cross-petition. You could issue your own petition on his unreasonable behaviour. You will have to get in quick if you are going to do this and it will increase the costs but it might make you feel a bit better.
I do want to be divorced but in my own time. I feel overwhelmed by it all. My ex sent me a petition ..none of the points are acceptable to me... I have been to sit down and go through it carefully and then see a solicitor but have felt quite stressed about it so have put it off. I told my ex I would get there but this morning I have a letter from his solicitor saying....the county court has confirmed exs Divorce Petition and that I should have filled in and returned the Acknowledgement of service form with the court within 8 days of receipt of papers. Do I have to return this within a certain time...is it a legal thing...if I dont reply straight away does it just go through? Feeling a bit stupid and fed up and cant see why we couldnt sit down and talk about it really. I have behaved calmly and well throughout our separation and he sends me letters from a solicitor.
