CMS Enforcement: Current Official Rules & Safeguards
These additions use current GOV.UK, DWP statistics and collection/enforcement guidance.
Direct Pay Must Normally Move to Collect & Pay Before Enforcement
Current DWP statistics guidance says CMS cannot begin enforcement while a case remains on Direct Pay. The arrangement must first move to Collect & Pay. For Collect & Pay cases, CMS pursues non-payment on the Receiving Parent's behalf.
Official unpaid-maintenance guidanceDeduction From Earnings Order
A DEO lets CMS require an employer to deduct maintenance directly from the Paying Parent's net earnings or pension. It can be used where maintenance is not paid, is underpaid, is late, or where payment direct from earnings is chosen.
DEO overview60% Protected Earnings — Specifically for DEOs
Employers must leave the employee with at least 60% of net earnings after the child-maintenance deduction. This is the protected-earnings proportion.
This safeguard applies to a Deduction from Earnings Order. It is not a general statutory cap applying to every CMS payment or enforcement method.
Protected earnings guidanceWhat Counts as Net Earnings for a DEO?
GOV.UK says DEO net earnings are calculated after Income Tax, Class 1 National Insurance and pension or superannuation contributions. Some payments count as earnings while certain benefits and statutory payments do not.
What counts as earningsCMS Can Make Bank Deduction Orders
CMS can recover unpaid maintenance directly from a Paying Parent's bank or building-society account through regular or lump-sum deduction orders where the statutory conditions are met.
Official enforcement optionsLiability Orders Are Still Court-Granted in Current DWP Guidance
Current GOV.UK liability-order guidance and the latest CMS statistics to March 2026 describe CMS as applying to a court for a liability order. The order legally recognises that a specified amount of maintenance was unpaid for a specified period.
This is important because proposals to accelerate enforcement should not be presented as though court-granted liability orders have already disappeared from the current system.
Current liability-order guidanceLiability-Order Reference Numbers Matter
DWP's liability-order guidance says each liability order has its own CMS reference number. If you want a payment applied to a particular liability order, quote that reference. Using only the general case reference can result in CMS deciding how the payment is allocated.
Payment allocation guidanceEnforcement Agents Can Follow a Liability Order
Once a court grants a liability order, CMS can refer the debt to enforcement agents. Current DWP statistics describe enforcement agents as able to seize goods and sell them to cover unpaid maintenance and costs.
CMS statistics to March 2026Property and Credit Consequences
A liability order can support registration of the debt on the Register of Judgments, Orders and Fines and can be followed by charging/order-for-sale action against property or assets, depending on the case.
Liability-order consequencesDriving Licence, Passport and Prison Are Last-Stage Sanctions
DWP's latest statistics say sanctions such as stopping a Paying Parent obtaining or retaining a driving licence or passport, or imprisonment, are used only after other methods of recovering unpaid maintenance have been attempted. DWP says it pursues these sanctions where it believes the Paying Parent can pay but is refusing to do so.
Current enforcement statisticsCurrent Scale of Enforcement
At the end of March 2026, DWP reported around 5,300 liability orders, 5,400 regular or lump-sum deduction orders, and 7,200 enforcement-agent referrals in process.
Latest CMS enforcement statisticsGet the Records Behind Enforcement
DWP's Subject Access Request process can be used to obtain CMS account information and evidence used in a dispute or investigation. Ask specifically for enforcement notes, decision history, payment allocation and records relevant to the disputed period.
DWP Subject Access RequestIf Enforcement Looks Wrong: Use the Correct Route
Different types of enforcement dispute require different remedies.
Important: Disputing Arrears Does Not Automatically Stop Enforcement
Sending evidence, making a complaint or submitting a Subject Access Request does not automatically suspend an enforcement action. If the underlying CMS decision is appealable, protect the applicable reconsideration/appeal deadline and tell CMS promptly why the debt is disputed and what evidence supports your position.
Important: A Liability Order Recognises Non-Payment for a Period — It Is Not a Substitute for Rechecking the Underlying Case
A court-granted liability order is a serious enforcement step. If you say the amount arose from an incorrect maintenance calculation, wrong effective date, missing payment credit or other underlying error, identify and challenge that issue through the route available for that decision. Payment records and allocation references can be especially important.

CMS Enforcement Powers, Liability Orders, Bailiff Action, Legal Rights, Evidence Standards & Challenging Incorrect Enforcement
The Child Maintenance Service (CMS) has legal powers to collect child maintenance where payments are not made voluntarily.
Enforcement action can be serious and may affect:
- Income
- Bank accounts
- Property
- Credit arrangements
- Employment
- Financial stability
Enforcement powers exist to help ensure that children receive financial support where maintenance is lawfully due.
However, enforcement action should be:
- Lawful
- Proportionate
- Evidence-based
- Fair
- Accurate
Parents have important rights where they believe enforcement action is based on incorrect information, disputed arrears, missing payments, or administrative errors.
For many Paying Parents, understanding enforcement powers and challenge rights is essential where concerns exist regarding false arrears, incorrect balances, or evidence that appears to have been overlooked.
CMS Enforcement Powers Explained
CMS has various enforcement powers available when maintenance remains unpaid.
These powers generally increase in severity depending on:
- Amount owed
- Payment history
- Attempts to resolve the matter
- Compliance with payment arrangements
Enforcement Options Available To CMS
Examples include:
Deduction from Earnings Orders (DEO)
Money taken directly from wages.
Deduction Orders
Money taken from bank or building society accounts.
Collection Through Collect & Pay
CMS collects payments directly.
Liability Orders
Formal legal recognition of debt.
Enforcement Agents (Bailiffs)
Used following certain legal processes.
Property Enforcement
In some circumstances.
Disqualification Applications
In certain cases involving driving licences or passports.
Deductions From Earnings (DEO)
A Deduction from Earnings Order allows CMS to require an employer to deduct child maintenance directly from wages.
What Can Be Taken?
This may include:
- Ongoing maintenance
- Arrears
- Collection fees where applicable
Employer Responsibilities
Employers must normally comply with a lawful DEO.
Protected Earnings Rules
Importantly, legislation provides Protected Earnings Rules.
This means a certain proportion of earnings must normally remain available to the employee after deductions.
CMS cannot simply take all available earnings.
If A DEO Appears Incorrect
You may wish to:
Request a breakdown.
Check income figures used.
Check arrears calculations.
Compare against payslips.
Request a Mandatory Reconsideration where applicable.
- Submit evidence.
Deduction Orders From Bank Accounts
CMS may also seek deductions from:
- Bank accounts
- Building society accounts
Where legal requirements are met.
Evidence Matters
Parents should carefully review:
- Account balances
- Payment histories
- Arrears calculations
before enforcement proceeds.
What Is A Liability Order?
A Liability Order is one of the most significant enforcement tools available to CMS.
Simple Explanation
A Liability Order is a legal document confirming that CMS believes child maintenance arrears are legally owed.
Once granted, additional enforcement powers may become available.
Why Liability Orders Matter
A Liability Order can be used to support:
- Enforcement Agent action
- Property-related enforcement
- Further recovery action
Does A Liability Order Mean The Debt Is Correct?
Not automatically.
Parents may still have concerns regarding:
- False arrears
- Missing payments
- Incorrect calculations
- Shared care disputes
- Evidence not considered
It is important to raise concerns as early as possible.

What Can Bailiffs Do?
Depending on the circumstances and legal authority available, enforcement agents may seek to:
