My partner pays maintenance for 2 kids - one is now over the age of 16 and has a full time job (i.e not eligible for maintenance payments anymore). He phoned the CMS 4 weeks ago to advise them of this and obviously they need to go and check with the ex - they aren't on speaking terms. He says his payments will change automatically and he will be advised via letter once she stops claiming child benefit. I don't think she will do this off her own back though!
Should we be phoning to check on progress of this? Will any change in payments be backdated?
Thanks!
