Hi all, I'm looking for some general advice if possible please. Me and my ex split in April last year and I filed for divorce in June. So far he has ignored two sets of papers that have been sent to him from the courts and now I am having to change my grounds just to be able to move forward. We have 6 children (the eldest being my daughter from a previous relationship) and so far we have managed to arrange visitation and such without too many arguments. The situation has now come to a point where due to his behaviour and threats of legal action I have now arranged for mediation to begin. My issue is I have given the address I know him to be living at to the mediation team so they can send him a letter about it and he is now stating he doesn't live there. He does have a flat in his name but has never spent a single night there, he moved in with his girlfriend and her daughter. This is where I drop the children off for his fortnightly weekend visits and also where I collect them from. What can I do if he pretends not to have received the letter and continues to deny living there? All he is doing is slowing down this process and making things harder. Is there a way I can prove he is living there? Do I have to send the letter to his flat? This is also the same for the amended divorce petition. I'm stuck on what to do? Any help would be greatly appreciated :)
