Child Maintenance After Divorce in England and Wales: Your Complete Plain-English Guide

When a relationship ends and children are involved, one of the most pressing questions is who pays for the children and how much. Child maintenance after divorce in England and Wales is a topic that causes a great deal of anxiety, and it is easy to feel overwhelmed by the rules, the calculations, and the process. This guide breaks everything down in plain English so you can understand your rights, your responsibilities, and your options without needing to pay a solicitor hundreds of pounds just to get basic answers.

What Is Child Maintenance and Who Has to Pay It?

Child maintenance is regular financial support paid by the parent who does not live with the child, known as the paying parent, to the parent who the child lives with most of the time, known as the receiving parent. The purpose is straightforward: to help cover the everyday costs of raising a child, such as food, clothing, and housing.

In England and Wales, child maintenance is separate from the divorce process itself. You do not need to be married to have a child maintenance arrangement, and divorcing does not automatically set one up. You will need to either agree an amount between yourselves or involve the Child Maintenance Service (CMS), which is the government body responsible for calculating and enforcing child maintenance.

Both parents have a legal responsibility to financially support their children, regardless of whether they were married, in a civil partnership, or simply living together. The child's welfare is the central concern, and the law in England and Wales takes that seriously.

It is worth noting that child maintenance is distinct from the financial settlement reached during divorce, which covers assets, property, and spousal maintenance. If you want a broader understanding of how finances are divided during a divorce, the Complete guide to divorce in England and Wales on Clarity Guide covers this in full.

Child maintenance typically applies until a child is 16 years old, or up to 20 years old if they remain in approved full-time education, such as A-levels or equivalent. University does not count for CMS purposes, though parents can make private arrangements for older children.

Family-Based Arrangements: Sorting It Out Yourselves

The simplest and most flexible option is a family-based arrangement, which means you and your ex-partner agree between yourselves how much maintenance will be paid and how often. There is no government involvement, no fees, and you can tailor the arrangement to your family's specific needs.

For example, you might agree that the paying parent contributes a set amount each month, pays for specific costs like school trips or uniform, or covers certain bills directly. This kind of flexibility is not possible through the CMS, which uses a fixed formula.

A family-based arrangement works best when both parents are communicating reasonably well and there is a degree of mutual trust. The main drawback is that it is not legally enforceable in the same way as a CMS arrangement. If the paying parent stops paying, your options are more limited unless you formalise the agreement.

You can make a family-based arrangement more secure by turning it into a consent order approved by a court. This gives it legal weight, though the court can only agree to include child maintenance in a consent order for 12 months, after which either parent can apply to the CMS. It is worth taking legal advice before drafting a consent order, but you can keep costs down by doing much of the groundwork yourself. Solicitors in England and Wales typically charge between £150 and £400 or more per hour, so being well-informed before any meeting saves money.

If you and your ex are on decent terms, starting with a family-based arrangement is sensible. You can always move to the CMS later if things break down.

How the Child Maintenance Service Calculates Payments

If you cannot agree privately, the Child Maintenance Service (CMS) is the official route. The CMS uses a set formula based on the paying parent's gross weekly income, which is taken directly from HMRC records. Here is how the rates work in 2026:

There are adjustments built into the calculation. If the paying parent has the child staying overnight, the amount is reduced. Specifically, for 1 to 52 nights per year, there is a small reduction. For 53 to 103 nights, the rate reduces by one seventh. For 104 to 155 nights, it reduces by two sevenths, and so on. This reflects the costs the paying parent incurs when the child is with them.

If the paying parent earns below a certain threshold, a flat rate or nil rate applies instead. For example, if they receive certain benefits or earn very little, they may pay a flat rate of just £7 per week, or nothing at all.

The CMS does not consider the receiving parent's income in its calculation, nor does it factor in wider living costs or debts. The formula is blunt but consistent. If you want to estimate what the CMS might calculate before making any decisions, the free divorce financial calculator on Clarity Guide can help you think through the numbers.

It is also worth knowing that the CMS calculation only applies to the first £3,000 of gross weekly income. If the paying parent earns more than this, the receiving parent can apply to court for a top-up order.

How to Apply to the Child Maintenance Service

Before you can apply to the CMS, you are required to use the Separated Families helpline (run by a service called Sorting Out Separation or through the CMS directly), unless you are exempt due to domestic abuse. The idea is to encourage a family-based arrangement before government services are used.

If you decide to proceed with a CMS application, you apply online or by phone. There is a one-off application fee of £20 for the person applying, though this is waived if you are under 19 years old or have experienced domestic abuse.

Once you apply, the CMS contacts the paying parent and gathers their income information from HMRC. A maintenance calculation is then issued, usually within a few weeks. Both parents are informed of the amount.

There are two main service types once the CMS is involved:

• Direct Pay: The CMS calculates the amount, but payments are made directly between parents. There is no collection fee, but the CMS does not enforce payment if the paying parent stops.
• Collect and Pay: The CMS collects payments and passes them on. This involves a fee: the paying parent pays an extra 20% on top, and the receiving parent receives 4% less. This service is used when Direct Pay has broken down or is not appropriate from the start.

Choosing Direct Pay where possible keeps more money in both parents' pockets. Collect and Pay is a safety net, not a first resort.

What Happens If the Paying Parent Refuses to Pay?

Unfortunately, non-payment is a real problem for many families. If you have a CMS arrangement and the paying parent stops paying, the CMS has enforcement powers that can be used after pursuing other options first.

If you are on the Collect and Pay service, the CMS can take the following enforcement steps:

• Deduction from earnings order: Payments are taken directly from the paying parent's wages or salary by their employer.
• Deduction order: Money is taken directly from the paying parent's bank account.
• Liability order: A court order that opens up further enforcement options, including bailiff action, charging orders on property, or even driving licence removal and, in serious cases, imprisonment.

These powers are genuine and the CMS does use them, though the process can be slow. If you are on Direct Pay and payments have stopped, your first step should be to contact the CMS and ask to move to Collect and Pay, or to request enforcement action.

If you have a privately agreed family-based arrangement with no court order, enforcement is harder. This is one reason why formalising the agreement matters if there is any doubt about reliability of payments.

Dealing with a non-paying ex is stressful and exhausting. If you are also going through the wider divorce process at the same time, understanding your rights around finances more broadly can help. The guide on separation agreements in England and Wales may also be useful if you are at an earlier stage of separation.

Child Maintenance and the Divorce Financial Settlement

It is important to understand that child maintenance and your divorce financial settlement are treated separately in England and Wales. When a court approves a divorce financial settlement, it deals with assets such as the family home, savings, pensions, and any spousal maintenance. Child maintenance sits outside this process and is handled either privately or through the CMS.

You cannot use a financial consent order to permanently fix child maintenance. As mentioned earlier, any child maintenance figure included in a consent order only holds for 12 months, after which either parent can go to the CMS for a fresh calculation. This prevents children from being locked into outdated arrangements as circumstances change.

One area where the two overlap is in relation to the family home. Courts sometimes allow the parent with primary care of the children to remain in the family home until the children reach a certain age, partly because stable housing supports the children's welfare. This is often called a Mesher order. However, this is a property decision, not a child maintenance decision.

If you are considering your overall financial position during a divorce, it is worth building a complete picture. Clarity Guide's guide on how much divorce costs in the UK helps you understand all the financial moving parts, from court fees to legal costs, so you can plan properly.

Getting clarity on these distinctions early on can save a great deal of confusion and conflict later. Many parents make assumptions about what their divorce settlement will cover, only to find child maintenance needs to be sorted separately. Being prepared makes the whole process smoother.

Reviewing and Changing a Child Maintenance Arrangement

Life changes, and child maintenance arrangements need to be able to change with it. If you have a CMS arrangement, there is a built-in annual review where the paying parent's income is reassessed using the latest HMRC data. If income has changed significantly, the maintenance amount will be adjusted accordingly.

Outside of the annual review, either parent can request a variation in certain circumstances. For example, if the paying parent has unearned income (such as rental income or dividends) that is not reflected in their PAYE salary, the receiving parent can ask the CMS to take this into account. Similarly, if the paying parent has significant assets or has reduced their income artificially to lower payments, a variation can be requested.

You can also request a change if the child's living arrangements change, for example if the child moves to live primarily with the other parent, or if overnight contact arrangements change significantly.

If you have a family-based arrangement and circumstances change, you simply need to discuss and agree a new figure. If you cannot agree, either parent can apply to the CMS at any point, as long as no court order restricting this is in place.

It is sensible to review any arrangement every year even if no formal review is triggered, to make sure it still reflects the reality of both parents' finances and the child's needs. Open communication, where it is safe and possible, makes this much easier.

A note for readers in Scotland: child maintenance works differently under Scots law and the CMS system applies across Great Britain, but some aspects of private arrangements and court orders differ.
