I know issues with child maintenance is a regular topic on MN and have read appalling stories on here in the past. Thought people might be interested in this survey by Gingerbread: www.gingerbread.org.uk/our-work/news-and-views/tell-us-about-your-experiences-of-child-maintenance/
Hope this is ok to post, I have no links to Gingerbread but thought it might be a good opportunity to get voices heard on what is currently a mess of a system
