Hey , new to this site and just want some advice really I have 2 children .. 1 child I am on birth certificate the other I am not . I have a private arrangement however CMS send letters to both parents wirh what I earn is this allowed , as you can imagine the stress it’s causing me as I am constantly getting messages if not from the mums it’s from Cms I recorded 8 letters in 14 days from them it made me really ill.. anyways is there anyway can stop the letters ? The child that I’m not on birth certificate the mum constantly disappears I have asked for DNA test to prove the child is mine but as soon as I contact she goes CMS I have never seen this child , and all I got from Cms was that I am alleged ??? it’s just one stress I am struggling with , any help advice would be welcoming
