When a relationship ends, making sure your children are financially supported is one of the most important things you will deal with. Child maintenance after divorce in England and Wales can feel complicated, but the rules are clearer than many parents realise. This guide walks you through how maintenance works, how it is calculated, and what you can do if things go wrong.

What Is Child Maintenance and Who Has to Pay It?

Child maintenance is regular financial support paid by one parent to the other to help cover the everyday costs of raising a child. It is separate from any division of assets or spousal maintenance agreed as part of your divorce settlement.

In England and Wales, the parent who does not live with the child most of the time is usually the one who pays. This person is called the paying parent. The parent the child lives with most, or the one who receives the payments, is called the receiving parent.

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. Divorce does not change this obligation. Even if a parent has no contact with their child, they are still required to contribute financially.

Child maintenance covers children up to the age of 16. It can continue until the child turns 20 if they remain in approved full-time education, such as A-levels or a BTEC at school or college. It does not automatically extend to university.

It is worth noting that these rules apply specifically to England and Wales. If you or your former partner lives in Scotland, different arrangements apply through a broadly similar system but with some procedural differences. You can read more in our guide to divorce with children in Scotland.

How to Arrange Child Maintenance: Your Three Main Options

There is no single route to arranging child maintenance, and many families sort it out without any official involvement. Here are the three main ways it can be set up in England and Wales.

  1. A family-based arrangement: You and your ex-partner agree between yourselves how much will be paid, when, and how. This is sometimes called a private or voluntary arrangement. There are no fees involved and it offers the most flexibility. However, it is not legally enforceable, which means if payments stop, you would need to move to a formal arrangement.
  2. A consent order through the courts: If you reach an agreement, you can ask the family court to turn it into a legally binding consent order. This gives both parties more security. However, even a court order cannot be enforced indefinitely; after 12 months, either parent can apply to the Child Maintenance Service (CMS) instead. Solicitors typically charge £150 to £400 or more per hour to help with this, so costs can add up quickly.
  3. The Child Maintenance Service (CMS): If you cannot agree, either parent can apply to the CMS, which is a government service that calculates the correct amount and, if needed, collects and passes on payments. There is a one-off application fee of £20 for the paying parent (receiving parents do not pay to apply). The CMS uses a set formula based on the paying parent's income, so there is less room for dispute about the figure itself.

Most families start with a family-based arrangement. If things break down, moving to the CMS is a straightforward next step.

How the Child Maintenance Service Calculates Payments

The CMS uses a fixed formula to work out how much the paying parent should contribute each week. The calculation is based primarily on the paying parent's gross weekly income, as reported to HMRC through tax returns or employer records.

Once the CMS has confirmed income, it applies the following rates:

Number of childrenPercentage of gross weekly income
1 child12%
2 children16%
3 or more children19%

These percentages apply to income between £100.01 and £3,000 per week. There are reduced rates for lower incomes and a flat rate of £8 per week for those on certain benefits. Income above £3,000 per week is not automatically included in the standard calculation, but the receiving parent can ask the CMS to consider it.

Shared care reduces the amount: If the paying parent has the child overnight for at least 52 nights per year (roughly one night per week), the calculation is reduced. The more overnight stays the paying parent has, the lower their weekly payment. This can be a source of disagreement, so keeping a record of overnight stays is sensible.

The CMS can also take into account other children the paying parent is financially responsible for, which may reduce the overall figure. If you want to get a rough idea of what might be owed, our free divorce financial calculator can help you think through the numbers before making any formal applications.

When Can You Change or Stop Child Maintenance Payments?

Child maintenance is not fixed forever. Either parent can request a review if their circumstances change significantly. This is called a variation through the CMS, or simply a renegotiation if you have a private arrangement.

Common reasons a review might be requested include:

  • The paying parent loses their job or their income drops significantly
  • The paying parent receives a significant pay rise
  • The number of overnight stays with the paying parent changes substantially
  • The paying parent has additional children they are financially responsible for
  • The paying parent has certain special expenses, such as costs related to a disability

The CMS carries out a standard annual review to check whether the paying parent's income has changed. If a larger change has happened between reviews, either parent can ask for an earlier reassessment.

When does child maintenance stop? Payments automatically end when the child turns 16, or 20 if they remain in full-time non-advanced education. If the child leaves education early or turns 20, maintenance ends even if they have not finished their course. There is no automatic obligation to support a child through university under the CMS system, though parents can of course agree this privately or a court may consider it in some circumstances.

If the receiving parent remarries or enters a new civil partnership, this does not affect child maintenance. Maintenance is for the child, not the parent, so it continues regardless of the receiving parent's relationship status.

What Happens If the Paying Parent Refuses to Pay?

Unfortunately, missed or withheld payments are a reality for many families. If you have a private arrangement and payments stop, your first step should be to try to resolve it directly. If that fails, you can apply to the CMS to take over the arrangement.

If payments are already being managed through the CMS and the paying parent falls behind, the CMS has a range of enforcement powers it can use, including:

  • Deductions from earnings orders: Payments are taken directly from the paying parent's salary by their employer.
  • Deductions from bank accounts: The CMS can apply to take money directly from the paying parent's bank or building society account.
  • Referral to a court: In serious cases, the CMS can refer the matter to a court, which has the power to issue a committal order (imprisonment) or remove a driving licence.
  • Charging orders on property: Unpaid maintenance can be secured against the paying parent's property.

The enforcement process can be slow, and it is not always straightforward. Keeping clear records of what has been paid and when will help if you ever need to demonstrate arrears.

Child Maintenance and Your Divorce Settlement: Understanding the Difference

It is important to understand that child maintenance is separate from your divorce financial settlement. The two processes run alongside each other but they are governed by different rules and handled by different bodies.

Your divorce financial settlement covers how you split assets such as the family home, savings, pensions, and debts. The family court oversees this, and anything agreed can be made into a binding consent order. Solicitors, mediators, or services like Clarity Guide (from just £37) can help you navigate this process without spending thousands on legal fees.

Child maintenance, by contrast, is calculated based on income rather than assets. You cannot trade it away as part of your financial settlement. For example, you cannot agree that the paying parent keeps a larger share of the pension in exchange for paying no child maintenance. The courts will not approve this kind of arrangement, and the CMS will not be bound by it either.

What you can do is reach a family-based agreement on top of the standard CMS amount. For instance, parents sometimes agree that one will pay school fees or contribute to extra-curricular activities separately. This is perfectly lawful, as long as the core maintenance obligation is still being met.

If you are trying to work out how all the financial pieces fit together after separation, our free divorce financial calculator is a helpful starting point before you speak to a solicitor or make any formal applications.

Many parents also find it useful to put any private agreements in writing in a separation agreement, even if it is not a court order. This creates a clear record of what was agreed. You can learn more about this in our guide to separation agreements in England and Wales.

Practical Tips for Managing Child Maintenance After Divorce

Getting the practical side right can save a great deal of stress further down the line. Here are some straightforward steps to help things run smoothly.

  • Put agreements in writing: Even if you have a friendly arrangement with your ex-partner, write down what has been agreed, including the amount, payment date, and bank details. This protects both of you if memories differ later.
  • Keep records of all payments: Save bank statements or payment confirmations showing every transfer. If a dispute arises, clear evidence makes everything easier.
  • Track overnight stays: If shared care is relevant to your calculation, keep a simple diary of when the children stay with each parent. Discrepancies in shared care are one of the most common reasons maintenance arrangements break down.
  • Review the arrangement regularly: Life changes, and what worked two years ago may no longer be fair or accurate. Build in an annual review as a matter of course, even if you are on good terms.
  • Use the CMS tool: The CMS has a free online calculator on the government website that gives you an indicative figure based on the paying parent's income. Running this calculation before any formal discussions helps set realistic expectations.
  • Get advice before signing anything: If you are asked to sign a consent order or any formal agreement that mentions child maintenance, it is worth understanding exactly what you are agreeing to. A one-hour consultation with a family solicitor (typically £150 to £400) or a plain-English resource like Clarity Guide can help you understand your position without committing to expensive ongoing legal representation.

The most important thing is to keep the focus on what is best for the children. When both parents understand the rules clearly, it is much easier to have productive conversations and reach fair outcomes.

Frequently Asked Questions

The amount depends on your gross weekly income and how many children you are supporting. The Child Maintenance Service uses a standard formula: 12% of gross weekly income for one child, 16% for two, and 19% for three or more. If you share overnight care, the amount is reduced. You can get an indicative figure using the free CMS calculator on the government website.
Yes. Many parents make a private, family-based arrangement between themselves without any third-party involvement. This can be flexible and avoids the CMS application fee. However, private arrangements are not automatically legally enforceable, so if payments stop, you would need to apply to the CMS or seek a court order.
No, not automatically. Child maintenance continues until the child is 16, or until they turn 20 if they remain in full-time non-advanced education, such as A-levels or a BTEC at school or college. It does not extend to university under the standard CMS rules, though parents can agree to make additional contributions privately.
If you have a private arrangement and payments stop, your first step is to try to resolve it directly. If that fails, you can apply to the Child Maintenance Service, which can calculate the correct amount and, if needed, use enforcement powers such as deductions from earnings or bank accounts. Keeping records of all payments and missed payments will support your case.
No. Child maintenance is for the child, not for either parent. If the receiving parent remarries or enters a new civil partnership, payments continue as before. If the paying parent remarries and has new children to support, this may be taken into account in a CMS calculation, but it does not remove the obligation to support existing children.
You cannot use child maintenance as a bargaining chip in your financial settlement. The courts will not allow arrangements where, for example, one parent waives maintenance in exchange for a larger share of assets. However, parents can agree on additional financial support on top of the standard CMS amount, such as school fees, as part of a wider financial agreement.
The Child Maintenance Service operates across Great Britain, including Scotland, and uses the same income-based formula. However, Scottish family law has some differences in how divorce and financial matters are handled overall.
