My Xh was paying maintenance for our dc when he first left. However he soon stopped paying when he met his new partner as she earns to support them both. I've not received a penny since and I've heard that they are now moving abroad, where he will work. The problem is I'm not sure where they are moving to so I'm not sure if the csa can be used or whether ill have to get a remo. Is there anyway that I can trace him if I have no idea where in the world he is? He hadn't seen our dc for 5 years, and has had no contact except for the odd birthday card that I made clear was not welcome.
