Appealing to the First-tier Tribunal
The Social Security and Child Support (SSCS) tribunal is part of HM Courts & Tribunals Service — genuinely independent of the CMS and DWP. It does not review the CMS's decision for reasonableness; it re-decides the case on the law and evidence. It is free, designed for unrepresented parents, and it corrects CMS decisions regularly.
Prerequisites and deadline
- You need a Mandatory Reconsideration Notice first — see MR.
- Appeal within one month of the MRN date. Late appeals up to 13 months are possible with reasons, at the tribunal's discretion — the tribunal, not the CMS, decides whether to admit a late appeal.
- Use form SSCS2 ("Appeal a Child Maintenance Group decision by the DWP"), available on GOV.UK, sent to HMCTS with a copy of the MRN.
Who is involved
Child maintenance appeals are unusual: both parents are parties, along with the Secretary of State (represented, sometimes, by a DWP presenting officer). Whatever you file is disclosed to the other parent, and vice versa. Address confidentiality is protected if you ask — flag any safety concerns on the SSCS2.
What the tribunal can and cannot do
| Can | Cannot |
|---|---|
| Re-make the decision entirely: income, bands, shared care, variations, effective dates | Hear complaints about CMS conduct, delay or advice (that is the complaints ladder) |
| Direct disclosure: company accounts, bank statements, tax records; summon witnesses; take evidence on oath | Enforce payment of what it decides (enforcement remains with the CMS) |
| Decide the case afresh even where the CMS refused a variation at the sift | Take account of changes of circumstances arising after the decision under appeal — it decides the case as at the decision date |
| Increase or decrease the assessment — appeals can go either way for either parent | Award costs or compensation |
The process, step by step
Lodge the SSCS2
State your grounds by element, as in your MR, and say whether you want an oral hearing. Choose an oral hearing. Success rates are consistently higher when the tribunal can ask questions; paper determinations favour the status quo.
The CMS response
The Secretary of State must file a response with the evidence held — often the first time you see the full basis of the decision. Read it forensically; note what is missing.
Directions and disclosure
Ask early, in writing, for any directions you need: disclosure of the other party's accounts or bank statements in variation cases, HMRC data, CMS call recordings. Tribunals grant focused, justified requests.
Prepare your bundle
A paginated, indexed set: decision letters, MRN, your evidence, a one-page chronology, and a short skeleton argument — what is wrong, what the right figure is, and the rule that gets you there. Precision beats volume.
The hearing
Usually a judge, sometimes with a financially qualified member; increasingly by video. Expect direct questions. Answer what is asked, concede what is true, and keep returning to your strongest documented points. Hearings typically run well under a day; listing takes roughly six months in current backlogs.
The decision
Given orally or by post. If you lose and believe the tribunal erred in law, request a statement of reasons within one month — the essential first step to the Upper Tribunal.
The FtT's disclosure powers are the sharpest tool in the system for dividend, company-profit and diversion cases — see HH v SSWP [2021] UKUT 280 on the tribunal's role as an expert fact-finder. Paying parents: the same powers mean your full finances may be examined; if your position is sound, that examination is your friend.
