Child Maintenance & Financial Provision on Divorce - How It's Calculated

Summary

Every parent has a duty to provide financial provision for his or her children, and sometimes step-children. When parents separate or divorce, typically, one parent becomes the primary carer , and the other parent contributes financially to the maintenance of that child when not in their care. Financial provision for children can include obligatory child maintenance (calculated by the Child Maintenance Service), top up child maintenance or other appropriate payments to cover expenses such as housing or school fees, for example. It may be possible for parents to come to an agreement between themselves as to the amount and regularity of maintenance payments. Where an agreement cannot be reached, parents can apply to the Child Maintenance Service (CMS) to calculate and action the appropriate provision. A child maintenance top up order can be pursued through the Court when the non-resident parent is a high earner and their gross income exceeds the maximum assessment through the CMS. This is currently £156,000 per annum. This article explains what child maintenance is and when it applies, how statutory child maintenance is calculated under CMS rules, and what additional financial.

• •This article explains what child maintenance is and when it applies, how statutory child maintenance is calculated under CMS rules, and what additional financial provision may be available for children beyond regular maintenance. It also answers common questions that arise during divorce, including how shared care affects the amount paid and what happens when income changes. The aim is to help you understand the framework so you can make informed decisions and, where possible, reduce conflict.
• •Child maintenance is money paid by one parent to the other (or, in some cases, to the person the child lives with) to contribute towards the child’s everyday costs. It is intended to support the child’s needs, rather than to equalise household incomes or compensate a parent for the end of the relationship. Typical costs covered include food, clothing, utilities, transport, and general activities. In practice, families often treat it as part of the overall financial planning that allows the child to live reasonably in both homes.
• •Child maintenance usually becomes relevant when parents separate and the child lives with one parent more than the other, or where there is a clear “paying parent” and “receiving parent”. It can apply whether parents were married, in a civil partnership, or never married. It can also apply where the child lives with a grandparent or other carer, depending on the circumstances.
• •Parents can agree child maintenance between themselves. This is often called a family-based arrangement. It can be flexible, private, and adapted to a child’s changing needs, for example by covering clubs, travel, or childcare in a way that feels fair. However, informal agreements can become difficult to manage if communication breaks down or one parent’s income changes.
• •If making a family-based arrangement the CMS website provides a calculator on their website that anyone can use to determine the correct child maintenance the paying parent should be paying the receiving parent.
• •If agreement is not possible, or if either parent wants the certainty of a standard calculation, an application can be made to the CMS. The CMS uses a statutory formula to calculate the amount payable and can collect and enforce payments if needed. Generally, the family court does not make routine child maintenance orders as the CMS has jurisdiction, but the court can still make orders for certain additional financial provision for children, such as school fees, lump sums, or housing, where the legal criteria are met.
• •The CMS calculation is built around the paying parent’s gross weekly income, usually taken from HM Revenue and Customs information. The CMS then applies a percentage based on the number of qualifying children and makes adjustments for other factors. The result is a weekly amount, typically paid monthly in practice.
• •As a broad guide, where gross weekly income falls within the main band used for standard calculations, the percentages commonly applied are 12% for one child, 16% for two children, and 19% for three or more children. Different rules and reduced percentages can apply in other income bands, and there are minimum rates where income is low. The CMS also has a cap on the income it considers in the standard formula. If the paying parent’s income exceeds that cap, the receiving parent may need to consider whether an application to the court for additional provision is appropriate, depending on the facts.
• •Shared care is a key adjustment. If the children stay overnight with the paying parent, the maintenance amount reduces based on the number of nights per year. The reduction is applied in bands. More overnight care generally means a lower payment because the paying parent is meeting more day-to-day costs directly during contact. Where care is broadly equal, the calculation can reduce significantly, and in some scenarios no maintenance may be payable under the statutory formula. However, equal time does not automatically mean equal costs, so parents sometimes agree additional contributions privately for specific expenses even where the CMS calculation is low.
