Hi, a family member has been taken to CMS (very bad relationship with ex). Turns out ex gave false information (address/ contact) and said they hadn't had any money from ex at all previously (they had).
Family member has now found out that they have an attachment of earnings of around £600 per month for maintenance and arrears. They are very upset and left without much spare money as they were trying to save to go to court for access (none allowed by ex for months).
My question is are they able to get this amount changed, e.g. Show evidence of bank transfers and of other children at current address which would affect calculations, as family member believes this is now set in stone and they cannot challenge.
