About CMS Help
CMS Help supports paying parents who face disputed amounts, unexplained arrears,
and enforcement that may not match a correct calculation.
Start simple: on the home page, pick the line that matches your situation.
You do not need an account to check figures or draft a letter.
What we stand for
- Children are entitled to support — the amount should be correct and explained.
- Paying parents deserve clear figures, written breakdowns, and a fair way to challenge mistakes.
- Published claims are checked against official sources before they go live — see Findings.
- Older Child Support Agency (CSA) debt is kept separate from current Child Maintenance Service (CMS) calculations.
What this site provides
- Clear home-page guidance on what to do if you disagree with CMS
- A rough estimate calculator and an arrears check with Excel download
- A browser timeline plus My Case accounts to store evidence and download your documents
- Save your home-page timeline and audits into My Case when you are signed in
- Letter drafts for the full CMS process (Word and PDF)
- Dispute and enforcement guides, plus Findings from the National Audit Office (NAO), Public Accounts Committee (PAC), and Department for Work and Pensions (DWP)
- A Freedom of Information (FOI) register for transparency work
