Enforce a Child Maintenance Order in the UK: 7 Powerful Steps When Parents Refuse to Pay

Enforce a Child Maintenance becomes the only option left when a parent simply stops paying what they owe their own child. If you’re the parent chasing missed payments, you already know how draining this gets, both financially and emotionally. The good news is that the Child Maintenance Service (CMS) has real legal teeth, and understanding how those powers actually work can save you months of frustration.

In the UK, child maintenance is meant to be straightforward: the parent who doesn’t have the child living with them most of the time pays a regular contribution toward the child’s upkeep. In practice, thousands of receiving parents deal with missed payments, partial payments, or paying parents who simply go quiet. When that happens, the CMS steps in with a set of escalating tools, ranging from taking money straight out of a payslip to, in the most stubborn cases, applying for prison time.

This article walks through exactly what child maintenance enforcement looks like in England and Wales: how arrears build up, what powers the CMS can use, how long each step tends to take, and what you can do to keep the process moving. Whether you’re just starting to notice missed payments or you’ve already been dealing with arrears for months, knowing the process gives you a clearer sense of what to expect and how to push things forward.

What Is a Child Maintenance Order in the UK?

A child maintenance arrangement is the legal mechanism that requires a non-resident parent to contribute financially to their child’s day-to-day living costs. It isn’t optional, and it doesn’t disappear because parents were never married or never lived together. The obligation follows the child, not the relationship status of the parents.

There are two main routes parents can take:

• Family-based arrangements – an informal agreement between parents, with no CMS involvement and no legal enforcement attached unless it’s later turned into a court consent order.
• Statutory CMS arrangements – calculated and, where needed, collected by the Child Maintenance Service under the Child Support Act 1991.

Most enforcement problems arise within statutory arrangements, because that’s where the CMS has the legal authority to step in. If you have a private, family-based deal that has broken down, you generally need to apply to the CMS first before any of the enforcement steps below become available to you.

Why Parents Fail to Pay Child Maintenance

Non-payment happens for a mix of reasons, and understanding the cause sometimes helps decide which enforcement route makes sense.

• Genuine financial hardship – job loss, illness, or a drop in income.
• Deliberate avoidance – hiding income, working cash-in-hand, or disputing paternity to delay payment.
• Disagreement over the calculation – some paying parents withhold payment because they believe the assessed amount is wrong, rather than going through the proper variation or appeal process.
• Breakdown in communication – especially in high-conflict separations, where maintenance becomes tied up with wider disputes over contact or custody.

Whatever the reason, arrears are treated as a legal debt once they’ve built up under a CMS arrangement, and the service has statutory authority to pursue them regardless of the paying parent’s excuse.

Direct Pay vs Collect and Pay: Why It Matters for Enforcement

The CMS runs two payment services, and which one you’re on affects how enforcement plays out.

Direct Pay is where the CMS calculates the amount owed, but the parents arrange the actual transfer of money between themselves. If payments stop under Direct Pay, the CMS doesn’t automatically know. The receiving parent has to report the missed payment before anything can happen.

Collect and Pay is where the CMS collects the money from the paying parent and passes it on. This service comes with collection charges: broadly, an additional percentage added to what the paying parent owes, and a smaller percentage deducted from what the receiving parent gets. If a parent has a history of missed payments, moving from Direct Pay to Collect and Pay is usually the first practical step, because it puts the CMS in direct control of collection and gives it visibility over exactly what’s been missed.

If you’re currently on Direct Pay and payments have stopped, ask the CMS to switch you to Collect and Pay. This single move often triggers the enforcement process far faster than continuing to chase the other parent yourself.

How to Report Non-Payment to the CMS

Before any enforcement action can begin, the CMS needs to know a payment has been missed. Reporting it is simple but worth doing properly:

1. Contact the CMS as soon as a payment is late. Don’t wait for a pattern to form; report it immediately.
2. Keep records of missed or partial payments, dates, and any communication with the other parent about money.
3. Ask to move to Collect and Pay if you’re currently on Direct Pay and the missed payments continue.
4. Request a written statement of arrears once the CMS confirms how much is owed.

Once the CMS is aware of a shortfall, it will usually contact the paying parent to try to recover what’s owed and explain what action may follow if payment still doesn’t happen.

Child Maintenance Enforcement Powers Explained

This is where the process actually gets teeth. The CMS enforcement toolkit is designed to escalate, starting with administrative measures and only reaching the courts when softer options fail.

Deduction from Earnings Orders

This is usually the first serious enforcement step. The CMS can order an employer to take the maintenance payment directly out of the paying parent’s wages before it even reaches their bank account. It requires no court hearing and can be set up relatively quickly once arrears are confirmed. According to the CMS’s most recent published figures, over a quarter of paying parents on the Collect and Pay service now have a deduction from earnings order in place, making it one of the most commonly used tools.

Deduction Orders on Bank Accounts

If the paying parent is self-employed or their employment situation makes a deduction from earnings order impractical, the CMS can apply a deduction order directly to a bank account. Since 2018, this has included joint accounts and business accounts, closing a loophole that previously let parents shield income by keeping money out of a personal account.

Liability Orders

When administrative deductions aren’t possible or aren’t working, the CMS can apply for a liability order through the courts. Since reforms introduced in 2023, this process has become largely administrative, cutting the typical timescale down to roughly six weeks in straightforward cases rather than requiring a full contested court hearing. A liability order doesn’t recover the money itself, but it unlocks further legal action.

Enforcement Agents and Charging Orders

Once a liability order is granted, the CMS can refer the case to enforcement agents (formerly known as bailiffs), who are legally allowed to seize goods and sell them to cover the debt. Alternatively, unpaid arrears can be secured against the paying parent’s property through a charging order, meaning the debt has to be settled if and when the property is sold.

Disqualification from Driving or Holding a Passport

For persistent non-payers, the CMS can apply to the courts to suspend a driving licence or passport for up to two years. This tends to be reserved for cases where other enforcement routes have already been tried and failed, since it doesn’t directly recover any money but instead applies pressure through restricting the parent’s freedom of movement.

Curfew Orders

Introduced under more recent enforcement legislation, curfew orders are a newer addition to the CMS toolkit, allowing restrictions to be placed on a non-paying parent’s movements as a further deterrent, separate from driving or passport disqualification.

Committal to Prison

Imprisonment is the last resort and is used rarely. It requires a court to find that the parent has wilfully refused to pay despite having the means to do so. Sentences are short, generally described as up to around six weeks, and the aim is almost always to prompt payment rather than to punish through a lengthy custodial term. In practice, very few cases reach this stage, since most non-payers settle once faced with the earlier enforcement steps.

Enforcement Timeline: What to Expect

One of the most common frustrations for receiving parents is not knowing how long enforcement takes. Roughly, the process tends to move like this:

1. Missed payment reported – action from the CMS typically begins within a few weeks.
2. Deduction from earnings or bank account attempted – usually the fastest route if the paying parent is employed or has identifiable income.
3. Liability order application – if deductions fail or aren’t viable, expect around six weeks for the administrative liability order process.
4. Enforcement agents, charging orders, or licence disqualification – timescales vary significantly depending on the case and whether court hearings are needed.
5. Committal proceedings – rare, and only after every other route has been exhausted.

There’s no single fixed timeline, and complex cases (self-employment, hidden income, parents living abroad) tend to move slower. Staying in regular contact with your CMS case manager and asking for updates helps keep pressure on the process.

Collection Fees and Arrears

It’s worth understanding the cost structure, because it affects both parents. Under the Collect and Pay service, the paying parent has an additional percentage added on top of the maintenance amount, while the receiving parent has a smaller percentage deducted from what they receive. These charges exist specifically to encourage parents to keep up with Direct Pay arrangements where possible, since Collect and Pay is more resource-intensive for the CMS to administer.

Arrears themselves don’t disappear if a parent stops paying and later starts again. The CMS is required to recover any backdated amount owed, on top of ongoing payments, which is why arrears can often stretch collection timelines out considerably once they’ve built up.

What If the Paying Parent Lives Abroad or Is Self-Employed?

These two scenarios cause the most delays in child maintenance enforcement cases.

Self-employed paying parents can be harder to assess accurately, since their declared income may not reflect their actual earnings. If you suspect the figures don’t add up, you can apply for a variation, asking the CMS to look at additional income, assets, or lifestyle inconsistencies that suggest the official income figure is too low.

Parents living abroad fall outside the CMS’s direct enforcement powers in most cases, though reciprocal arrangements exist with certain countries that allow maintenance orders to be recognised and enforced overseas. If the other parent has moved abroad specifically to avoid payment, it’s worth raising this with the CMS early, since it changes which enforcement routes are actually available.

Appealing or Challenging a CMS Decision

Enforcement isn’t only something that happens to paying parents; sometimes paying parents genuinely believe the calculation is wrong. If either parent disagrees with a CMS decision, the process generally works like this:

• Mandatory reconsideration – ask the CMS to review its own decision first. This step is required before anything else.
• Appeal to a Tribunal – if the reconsideration outcome is still disputed, an independent tribunal can review the case, usually within one month of the reconsideration decision.
• Upper Tribunal – further appeal is possible but only on limited legal grounds, not simply because one parent disagrees with the outcome.

Disputing a decision doesn’t pause the obligation to pay in most circumstances, so paying parents who ignore an assessment while waiting for an appeal outcome can still end up facing enforcement action in the meantime.

Tips for Receiving Parents Pursuing Enforcement

If you’re the one trying to get child maintenance enforcement moving, a few practical habits make a real difference:

• Report missed payments immediately rather than waiting to see if the parent catches up on their own.
• Push to move to Collect and Pay if Direct Pay keeps breaking down.
• Keep a paper trail of every missed payment, communication, and CMS reference number.
• Ask specific questions when you contact the CMS: which enforcement stage the case is at, what happens next, and roughly when.
• Consider independent legal advice if arrears are significant or the case involves self-employment, hidden assets, or a parent based overseas, since these situations often benefit from a solicitor’s involvement alongside the CMS process.

For general guidance on your rights and the current rules, the GOV.UK child maintenance service page is the most reliable starting point, and Citizens Advice offers free, practical guidance if you’re unsure which enforcement route applies to your situation.

Conclusion

Chasing unpaid child maintenance is exhausting, but the UK system does have a genuine enforcement structure behind it, moving from wage and bank deductions through to liability orders, asset seizure, licence disqualification, and, in the most extreme and rare cases, imprisonment. Understanding how child maintenance enforcement actually works, and knowing which stage your case is likely to be at, puts you in a much stronger position to push the CMS for action rather than waiting passively for arrears to be resolved.

If you’re currently dealing with a non-paying parent, reporting the missed payment straight away, moving to Collect and Pay where needed, and keeping detailed records are the most effective things you can do while the CMS works through its enforcement process.
