CMS Liability Orders: What They Actually Are (And What the Law Really Says)
Years of research and active High Court proceedings have exposed serious questions about whether CMS liability orders are legally valid court orders at all. Here is what you need to know.
What This Article Is About
Every year, the Child Maintenance Service seeks liability orders against tens of thousands of paying parents. These documents look like court orders. They are registered with Registry Trust Limited, which affects your credit record. They are used to justify wage deductions, bank account raids, driving licence removal, and ultimately committal to prison.
Years of detailed research - culminating in active High Court judicial review proceedings - has raised serious, documented questions about whether these documents are legally valid court orders at all. This article sets out what the research has found, in plain English, with the full statutory references so you can verify everything yourself.
This is not scaremongering. It is not an invitation to ignore the CMS. Do not ignore any summons or hearing. It is information that every paying parent subject to CMS enforcement deserves to know.
The Five Core Findings
The research document (March 2026, version 1.0) identifies five principal findings:
Finding 1: The summons is generated by CMS - not the court
The summons CMS sends you (template reference CMEL7298) is described in CMS's own staff handbook as an "off-system letter" - meaning it is generated on CMS's own computer system, not on the court's case management system (called Libra). A court-issued summons always carries a court reference number. The CMS summons carries only CMS's own internal reference numbers (called SCIN numbers).
The law requires a specific sequence before a summons can validly be issued. Under section 51 of the Magistrates' Courts Act 1980 and the landmark House of Lords authority R v Manchester Stipendiary Magistrate ex parte Hill [1983] 1 AC 328, a Justice of the Peace (or authorised court officer) must personally apply their judicial mind to each individual case and decide whether to authorise a summons. This is not a clerical act - it is a judicial act, and it must happen for each case individually.
The research suggests what actually happens is: CMS sends the court a bulk spreadsheet of names. A court officer reviews the entire list - not each individual case. Your case is one line on a spreadsheet. The House of Lords made clear in ex parte Hill that if a magistrate authorises a summons without applying their mind to the individual information, "he is guilty of dereliction of duty" and the summons is a nullity - void from the start.
Finding 2: The liability order document is generated by CMS - not the court
Since SI 2021/763 (which came into force in September 2021) abolished Schedule 1 of the Child Support (Collection and Enforcement) Regulations 1992, there is no longer a prescribed form for a liability order. HMCTS's own internal guidance (June 2023) confirms the consequence: "There is no longer a prescribed order and so the court does not produce one. The Council's software should generate a notice that the order has been made."
This means what CMS sends you as a "Liability Order" is, in law, a notification document - not the order itself. The order itself, in law, only exists when the designated officer records the adjudication in the court register under Rule 66 of the Magistrates' Courts Rules 1981. The register entry is the legal act that creates the order. The notification document CMS generates has no legal force unless it corresponds to an actual register entry.
A letter obtained from HMCTS (the "Veer email") confirms that in the cases under examination, no order is on the court file. Two CMS enforcement officials, captured on recorded calls, confirmed this directly: "no court orders - they're memorandums."
Finding 3: The court cannot question whether the debt is real - Article 6 ECHR
This is the most constitutionally significant finding. Section 33(4) of the Child Support Act 1991 contains what the research calls a "structural bar":
"For the purposes of this section, the court is not to question whether - (a) a maintenance calculation is, or was, correct; or (b) an amount of child support maintenance is, or was, payable."
This means that at a liability order hearing, even if:
- CMS has made an error in calculating what you owe
- You have already paid some or all of the money
- The debt has been calculated on income figures that are wrong
- The debt does not exist at all
...the court cannot examine any of this. It is required by law to accept CMS's assertion that the money is owed. The National Audit Office has confirmed that CMS accounts contain approximately £29.7 million in incorrectly calculated amounts. People are receiving orders for debts that may not exist - and the court is barred from looking at this.
The research argues this structural bar is incompatible with Article 6 of the European Convention on Human Rights - the right to a fair trial - and relies on the European Court of Human Rights authority Tsfayo v United Kingdom [2006] ECHR 981, which held that a later appeal does not cure an Article 6 violation that occurred at the enforcement stage.
The House of Lords confirmed the existence of the section 33(4) bar in Farley v Child Support Agency [2006] UKHL 31. The research argues this authority, read with the ECHR, makes the entire regime structurally incompatible with the right to a fair hearing.
Finding 4: The administrative route that would make this lawful has never been switched on
Parliament anticipated exactly this problem. In the Child Maintenance and Other Payments Act 2008 (section 25), Parliament enacted provisions - sections 32M and 32N of the Child Support Act 1991 - that would allow CMS to operate an administrative liability order regime without court involvement at all. If these provisions were in force, much of what CMS currently does administratively would be lawfully authorised.
These provisions were never commenced. No commencement order was ever made. This was confirmed by DWP Minister Andrew Western MP in a written parliamentary answer on 18 March 2026.
The significance is this: the fact that Parliament needed to pass new legislation to authorise an administrative route confirms that the current court-based route under section 33 CSA 1991 cannot be administratively bypassed. If it could be bypassed without legislation, the new provisions would have been unnecessary. CMS cannot self-authorise what Parliament has not enacted.
Finding 5: Serious Fraud Office referral on the basis of criminal law concerns
The research identifies potential concerns under the Forgery and Counterfeiting Act 1981 (sections 1, 3, and 9(1)(g)) and the Fraud Act 2006 (sections 2, 3, and 4) arising from the registration of CMS-generated documents with Registry Trust Limited as if they were court orders, when the research suggests they may not be court orders at all.
A referral has been made to the Serious Fraud Office (reference: RF26030143832C). Thames Valley Police crime references are also on record. These referrals are active. No charges have been brought. These are allegations, not convictions. They are cited here because they are verifiable public record and are relevant to understanding the seriousness with which the research is being pursued.
The Legal Process That Should Happen - Step by Step
For a CMS liability order to be legally valid, the following must occur:
- A formal complaint must be made by or on behalf of the Secretary of State to the magistrates' court - not submitted to itself (Regulation 28(1), SI 1992/1989).
- A JP or authorised court officer must personally apply their judicial mind to each individual case and decide whether to authorise a summons. Their name must be recorded by the designated officer (section 51 MCA 1980; ex parte Hill [1983] 1 AC 328).
- The summons must comply with Rule 98 of the Magistrates' Courts Rules 1981 (as substituted by SI 2019/1367), including identifying the court office address and containing a court reference number.
- A hearing must be held at which the court is individually satisfied that payments have become payable and have not been paid (section 33(3) CSA 1991 - the "satisfaction test").
- The adjudication must be recorded in the court register (Rule 66, MCR 1981). This is the legal act that creates the order. Without this register entry, there is no order - regardless of what documents CMS generates.
The research's central argument is that step 2 and step 5 are not being met - and that without them, any documents CMS sends you are not court orders in law, regardless of how they are labelled.
What to Look for on Your Own Documents
If you have received a CMS summons or liability order, check these things:
- Court reference number: A court-issued summons will have a court case reference number - not just CMS's internal SCIN reference number. If your summons shows only a SCIN number, ask the court directly whether it has a corresponding Libra (court system) entry.
- Who authorised the summons: The court is legally required to keep a record of the name of the JP or court officer who authorised your summons. Write to the court - not CMS - and ask for this name.
- Court office address: Since SI 2019/1367, a summons must state the name and address of the court office. If the only address is CMS's own address, this requirement may not be met.
- Court record of the liability order: Write to the court directly (not CMS) and ask: "Is there a record on the court file of a liability order made against me, including a register entry under Rule 66 of the Magistrates' Courts Rules 1981? Please provide the Libra case reference number."
What the Court Cannot Do - and Why This Matters
Even if you believe your maintenance calculation is wrong, you cannot raise this at the liability order hearing. Section 33(4) CSA 1991 prevents it. The only routes to challenge the calculation itself are:
- Mandatory Reconsideration - ask CMS to review the decision (strict time limits apply)
- First-tier Tribunal (Social Entitlement Chamber) - independent appeal of the calculation itself
These are separate from and must run alongside any challenge to the liability order process itself. If you have both a wrong calculation and a potentially invalid order, you need both processes running simultaneously.
Urgent: If You Have Already Received a Liability Order
If You Are at Risk of Committal to Prison
Committal proceedings (where CMS applies to have you imprisoned for non-payment) are the most serious stage of enforcement. If you are facing committal:
- Treat this as an emergency and seek legal advice today
- Contact your MP - they can raise urgent questions with DWP and CMS
- Contact a solicitor even if just for one emergency appointment
- Contact your local Law Centre (lawcentres.org.uk) for free legal advice

Debt Collection Agencies Are Returning Cases - What This Means
If a debt collection agency has been instructed to collect arrears from you and has returned the case without enforcing, this may be because their own compliance or legal teams have identified the same deficiencies described in this article - specifically:
- The absence of a court-generated order document (the order being a CMS-generated notification only)
- The absence of a Rule 66 register entry on the court file
- Uncertainty about whether the originating summons was validly authorised by a JP
- The risk of enforcement action being unlawful or void if the underlying order is itself defective
A debt collection agency that returns a case without enforcement is, in effect, declining to act on a document whose legal validity they cannot verify. This does not mean the debt is extinguished or that CMS cannot take other enforcement steps. The CMS may instruct a different agency, seek a fresh order, or use other enforcement routes. If your case has been returned by a DCA, you should:
- Keep a written record of when and how you were notified of the case return
- Write to the DCA and ask for the reason in writing
- Write to the CMS asking what enforcement action they intend to take next
- Seek legal advice promptly - the return of a case creates a window but it is not a permanent resolution
The fact that commercial debt collection agencies - whose business is debt recovery - are returning CMS arrears cases rather than enforcing them is one of the strongest real-world signals that something is fundamentally wrong with the documents CMS is issuing as liability orders.
The Official CMS Enforcement Documents May Not Be What They Claim
This is the core finding that underlies everything above, and it deserves to be stated plainly:
This is not a technicality. A debt enforcement regime that relies on documents that are not court orders - presented as if they are - and that uses those documents to justify wage deductions, bank raids, driving licence removal, and imprisonment, raises the most serious questions about rule of law and the rights of citizens. These questions are now before the High Court.
What This Research Does NOT Mean
To be absolutely clear about what this article is and is not saying:
- It does not mean you can ignore CMS. Orders can be made in your absence. Enforcement action can follow. Ignoring proceedings makes things worse.
- It does not mean the courts have agreed with these arguments. The High Court proceedings are active and have not concluded.
- It does not mean you do not owe the money. If you have a child maintenance obligation, that obligation exists regardless of whether the enforcement process is legally valid.
- It does not substitute for qualified legal advice. The research document itself says: "This document is research produced by a non-lawyer. It may contain errors. Nothing in it is legal advice."
What it does mean is that there are serious, documented, statute-referenced questions about whether the documents CMS sends you are legally valid court orders - and that those questions are being pursued in the High Court, before criminal investigation bodies, and are now affecting the willingness of commercial debt collection agencies to enforce. You have a right to know this.
