I had a private arrangement for the father of my two girls to pay child maintenance, but he stopped paying anything 2 months ago and said that because he is not working, he is nil assessed by CMS. I haven’t pursued it further because I phoned them and they said he is nil assessed. I have no evidence of what his income is, and have taken up a second job to keep afloat. Feeling very frustrated that there is nothing I can do but I need evidence to say that I am a single parent and struggling financially. Any advice please?
