I have been separated since December 2007. I know where my ex was then, but I have no idea if he is still there. We split all of the house and finances etc in 2008, but I have had no contact with him since then. How do I go about serving him with papers, and do I need a consent order as the finances have been settled? He has little or no family, so I can't use them to find him. Also, I have moved since and don't want him to know my new address. Can I keep my location private?
