When parents separate, the question is rarely whether a child needs financial support. The difficulty is agreeing what is fair, reliable and workable when household incomes, care arrangements and communication have changed. This guide to child maintenance rules explains the usual position in Northern Ireland, the routes available to parents, and when early legal advice can prevent a financial disagreement becoming a wider family dispute.
Child maintenance is money paid towards a child’s everyday living costs. It is separate from decisions about where a child lives, the time they spend with each parent, and parental contact. Those issues can affect the amount paid in some cases, but maintenance should not be used as a bargaining tool for contact.
Who can receive child maintenance?
A parent who does not live with their child for most of the time will often be expected to pay child maintenance to the parent or person with day-to-day care. This may also be a grandparent or another relative if they are the child’s main carer.
Maintenance is commonly payable until a child reaches 16. It can continue until age 20 where the child remains in approved full-time education or qualifying training. The precise position can depend on the child’s circumstances, including whether they have left education, started work or are receiving certain benefits.
The fact that a parent has a new partner, another household or a difficult relationship with the receiving parent does not, by itself, remove the responsibility to contribute. Equally, the receiving parent’s income is not usually part of the standard Child Maintenance Service calculation. The focus is principally on the paying parent’s income and the pattern of overnight care.
Guide to child maintenance rules: choosing an arrangement
There are three broad ways to arrange maintenance. The right option depends on the level of trust between parents, the regularity of income and whether both parties can communicate constructively.
Family-based arrangements
A family-based arrangement is an agreement made directly between parents. It can cover an amount, a payment date and how extra costs such as school uniform, childcare, clubs or holidays will be managed. It offers flexibility. For example, parents may agree a different approach where income is seasonal or where a child’s needs create higher regular costs.
The benefit is that parents retain control and can adjust the arrangement quickly. The risk is that a verbal understanding may become unclear over time, particularly after a change in employment, a new relationship or altered contact arrangements. Even where relations are good, it is sensible to record the agreement in writing and review it at agreed intervals.
Child Maintenance Service calculation
Where an agreement cannot be reached, either parent can ask the Child Maintenance Service, often called the CMS, to calculate maintenance. The CMS generally uses income information supplied by HM Revenue and Customs and applies statutory rules.
The calculation can take account of the paying parent’s gross weekly income, certain pension contributions, other children they support and the number of nights the child stays with them. A parent who provides regular overnight care may receive a reduction because they meet some day-to-day costs directly during those stays.
This is why clear, realistic records of overnight care can matter. Informal arrangements should not be overstated to reduce payments. Nor should a parent be denied recognition for genuine, established shared care simply because the arrangement is not written down. If there is disagreement, evidence such as calendars, messages and school arrangements may help clarify the position.
Direct Pay and Collect and Pay
After the CMS has made a calculation, parents may use Direct Pay, where the paying parent sends the money directly to the receiving parent. This can work well where payment is dependable, even if communication is limited.
If payments are missed or direct payment is unsuitable, the CMS may collect and pass on the money through Collect and Pay. Charges can apply under that service, so it is usually preferable to maintain a reliable direct arrangement where possible. However, a parent should not accept repeated late or missing payments merely to avoid using a formal collection route.
How maintenance amounts are worked out
There is no single figure that applies to every family. The statutory calculation uses several rates, and the outcome can differ significantly depending on income and family circumstances. A parent with a low income may pay a reduced or flat-rate amount. A parent with a higher income may pay more, while the CMS calculation is generally based on income up to a set limit.
The CMS can also consider variations in defined circumstances. Examples may include certain unearned income, income being diverted, significant assets producing income, or particular expenses connected with keeping in contact with a child. Variations are not automatic and should be supported with accurate information.
It is understandable to feel that a calculation does not reflect the full reality of family life. The statutory scheme is designed to provide a consistent starting point, not to account for every purchase or every disagreement. In some situations, particularly where there are substantial school fees, disability-related costs, complex business income or an existing court order, specialist advice is worthwhile before either parent makes assumptions.
When should a maintenance arrangement change?
Child maintenance should not be treated as fixed indefinitely. A genuine change in income, employment, benefits, overnight care or responsibility for other children may affect what is payable. A parent who loses work, has hours reduced or becomes self-employed should act promptly rather than allowing arrears to build up.
The same applies to the receiving parent. If the child begins staying overnight with the paying parent more often, or leaves qualifying education, that may require a review. The CMS should be told about relevant changes where it is managing the case. Parents with a private arrangement should discuss the change openly and confirm any revised agreement in writing.
Do not simply stop paying because you believe the amount is wrong. That can create arrears and may lead to enforcement action. If a calculation appears inaccurate, there are formal routes to ask for it to be looked at again and, where appropriate, challenged. Timescales matter, so retain letters, payslips, childcare information and records of payments.
What if a parent will not pay?
Missed payments can place real pressure on the household caring for a child. If Direct Pay has failed, the receiving parent can ask the CMS for support with collection and enforcement. The available action depends on the case, but may include deductions from earnings or benefits, deductions from bank accounts and further enforcement measures.
For the paying parent, ignoring correspondence is rarely sensible. If the amount cannot be paid due to a genuine change in circumstances, contact the CMS and obtain advice as soon as possible. A manageable response is far better than allowing debt and additional charges to grow.
It is also essential to keep maintenance separate from contact. A parent cannot lawfully withhold a child from the other parent because payments are late, and a parent should not withhold maintenance because contact is difficult. Both issues may need to be addressed, but through the appropriate process.
Where family law advice can help
Many maintenance cases can be resolved without solicitors. A straightforward agreement, made in good faith and kept under review, may be the least stressful outcome for everyone. Legal advice becomes particularly valuable where separation also involves divorce, disagreements about children, allegations of domestic abuse, uncertain income, property issues or an argument over shared care.
A solicitor can help you understand whether a proposed arrangement is realistic, record the terms clearly, and deal with connected family issues without losing sight of the child’s welfare. For families in Portadown, Craigavon and across Northern Ireland, JPH Law can provide sensible, practical advice in confidence.
The most useful arrangement is not necessarily the one that looks neatest on paper. It is the one that gives a child dependable support, reflects the actual care they receive, and can withstand the ordinary changes family life brings.
