Introduction to Variation of Child Maintenance

When it comes to child maintenance payments in the UK, a “variation” refers to a formal request to change the amount of money one parent pays to support their child. This adjustment can be made when circumstances change, such as a shift in income, extra costs relating to the child, or other significant financial developments. The Child Maintenance Service (CMS) is the government body responsible for assessing, collecting, and, if necessary, varying these payments to ensure they remain fair and appropriate for everyone involved.

The CMS uses a standard formula to calculate child maintenance, but this may not always reflect the specific needs or situations of individual families. That’s why it’s possible to apply for a variation if you believe the current arrangement no longer suits your circumstances. Understanding who can apply, the valid reasons for requesting a change, and what evidence is required is essential before starting the process.

It’s important to note that not every change in personal or financial situation will automatically qualify for a variation. The CMS will only consider certain grounds, such as additional income not previously declared, costs for supporting a child with a disability, or expenses like travel for contact with the child. Knowing the eligibility criteria and required documentation helps you prepare a stronger case and avoid unnecessary delays.

If you are considering changing your child maintenance arrangement, it’s a good idea to familiarise yourself with the process and your legal rights. The rules and procedures are set out in the Child Support Act 1991, which is the main piece of legislation governing child maintenance in the UK. For a more detailed overview of how variations work and practical steps you can take, you may also find the article on variation of child maintenance payments helpful.

Understanding these basics ensures you are better prepared to navigate the system and make informed decisions about your child’s financial support.

Who Is Eligible to Apply for a Variation?

When it comes to changing a child maintenance arrangement through the Child Maintenance Service (CMS), it’s important to understand who is eligible to request a variation. A “variation” means asking the CMS to look again at your current child maintenance calculation because you believe it does not reflect your real financial circumstances, or those of the other parent.

Who Can Apply?

Generally, either parent involved in a child maintenance case can apply for a variation. This includes:

  • The paying parent (sometimes called the “non-resident parent”): This is the person who pays child maintenance.
  • The receiving parent (sometimes called the “parent with care”): This is the person who receives child maintenance payments for the benefit of the child or children.
  • In some cases, a person with legal parental responsibility who is caring for the child, such as a grandparent or guardian, may also be eligible if they are registered as the receiving party in the CMS arrangement.

For more on the roles of paying and receiving parents, see this helpful overview.

Are There Any Restrictions?

There are a few conditions and restrictions to be aware of:

  • Active CMS Case: You can only apply for a variation if you already have a case open with the Child Maintenance Service. If you have a private or family-based arrangement, you must first register your case with the CMS.
  • Grounds for Variation: You must have a valid reason (or “ground”) for requesting a variation, such as extra income not included in the standard calculation, special expenses, or changes in circumstances. More about these grounds is explained in detail elsewhere on this page.
  • Timing: There are no strict time limits for applying for a variation, but it’s advisable to act as soon as you become aware of a change in circumstances.
  • One Application at a Time: Only one variation application can be considered at a time for each case. If you have already applied and are waiting for a decision, you must wait until it is resolved before making another request.

Examples of Who Can Apply

  • A paying parent whose income has decreased due to redundancy may apply to reduce their payments.
  • A receiving parent who believes the paying parent has additional income (such as from dividends or rental property) not included in the current calculation can request a variation to increase payments.
  • A parent with care who incurs extra costs for the child’s disability or education may also seek a variation.

Practical Advice

Before applying, it’s helpful to gather evidence to support your case, such as payslips, bank statements, or details of additional expenses. The CMS will review your application carefully and may ask for further information.

For a step-by-step guide on changing payments and the CMS’s role, see this article on the Child Maintenance Service.

Understanding who can apply for a variation and the conditions involved can help you make informed decisions about your child maintenance arrangement. If you believe your situation has changed, it’s worth considering whether a variation could help ensure the payments are fair and accurate.

Eligibility Criteria for Paying Parents

Eligibility Criteria for Paying Parents

If you are a paying parent under a Child Maintenance Service (CMS) arrangement in the UK, you may be able to request a variation to your child maintenance payments. Understanding the eligibility criteria is essential before making an application, as the CMS will only consider variations in specific circumstances.

When Can a Paying Parent Request a Variation?

You can apply for a variation if your current child maintenance calculation does not accurately reflect your financial situation. Common reasons include:

  • Changes in Income: If your gross weekly income has changed significantly (usually by at least 25%), you may be eligible to request a reassessment. This includes both increases and decreases in income.
  • Special Expenses: Certain costs, known as special expenses, can be considered for a variation. Examples include costs related to maintaining contact with your child (such as travel expenses), expenses for supporting children with disabilities, or costs associated with debts incurred for the benefit of the child. For a detailed discussion of what counts as special expenses, you can refer to this article.
  • Assets Not Accounted for in the Original Calculation: If you have assets worth over £31,250 (excluding your home and business assets), the CMS may consider this as grounds for a variation. This is relevant if your income from employment or self-employment does not reflect your overall financial position.
  • Unearned Income: If you receive significant unearned income, such as rental income, dividends, or interest, and it was not included in the original calculation, you can request a variation to have this income considered.

Evidence Required for Eligibility

To support your application for a variation, you must provide clear and relevant evidence. The CMS will require documentation that demonstrates your financial circumstances and supports your reasons for requesting a change. This might include:

  • Payslips or tax returns showing changes in income
  • Receipts or invoices for special expenses (such as travel costs for contact with your child)
  • Bank statements or financial documents relating to assets or unearned income
  • Evidence of debts incurred for the benefit of the child

Providing thorough and accurate evidence is crucial, as the CMS will only consider variations if there is sufficient proof of your eligibility. For more detailed legal guidance on what counts as evidence for eligibility, see this resource.

Practical Advice

  • Be Proactive: If your financial situation changes, notify the CMS as soon as possible. Delays could result in arrears or overpayments.
  • Keep Records: Maintain up-to-date records of your income, expenses, and any relevant financial changes.
  • Understand the Rules: The Child Support (Variation) Regulations 2000 set out the legal framework for variations. Familiarising yourself with these rules can help you prepare a stronger application.

If you are unsure whether your circumstances qualify for a variation, or what evidence you need to provide, it is advisable to review the official CMS guidance or seek professional legal advice. This will help ensure your application is as robust as possible and gives you the best chance of a fair outcome.

Eligibility Criteria for Receiving Parents

Eligibility Criteria for Receiving Parents

As a receiving parent – the parent or guardian who receives child maintenance payments – you may consider requesting a variation to your existing arrangement if your circumstances, or those of the paying parent, have changed. Understanding when you are eligible to apply for a variation, and the requirements involved, can help ensure you receive the correct level of support for your child.

When Can a Receiving Parent Request a Variation?

You can apply for a variation through the Child Maintenance Service (CMS) if you believe the current calculation does not accurately reflect the paying parent’s financial situation. Common reasons for requesting a variation include:

  • The paying parent has additional income: If you have evidence that the paying parent has income not included in the original assessment – such as earnings from self-employment, rental properties, or investments – you can ask the CMS to consider this.
  • Lifestyle evidence: If the paying parent’s standard of living appears higher than what their declared income would suggest, you may request a review.
  • Special expenses: If the paying parent is incurring costs not previously accounted for, like travel expenses for contact with the child, you may want to ensure these are fairly considered in the calculation.
  • Changes in the paying parent’s circumstances: If you know the paying parent’s financial situation has changed significantly (for example, a new job or increased earnings), you can ask the CMS to reassess the maintenance amount.

Requirements and Limitations for Receiving Parents

There are specific requirements and limitations for receiving parents seeking a variation:

  • Evidence is essential: You must provide clear evidence to support your request. This might include bank statements, payslips, or other documents showing the paying parent’s income or assets.
  • Grounds for variation are defined by law: Not every change in circumstance qualifies for a variation. The Child Support Act 1991 sets out the legal framework for when and how variations can be made. The CMS follows these rules strictly.
  • Application process: You must apply to the CMS, outlining the reason for your request and supplying any supporting documents. The CMS will review your application and may contact both parents for more information.
  • Possible outcomes: The CMS may decide to increase, decrease, or leave the payment amount unchanged, depending on the evidence and circumstances.

Practical Advice

  • Be specific: Clearly explain why you believe the current arrangement is unfair or inaccurate.
  • Act promptly: If you become aware of changes in the paying parent’s circumstances, apply for a variation as soon as possible. Delays could affect the amount you receive.
  • Stay informed: Rules and procedures may change over time. For up-to-date information on how the CMS operates and recent developments, you may find the Child Maintenance Service inquiry report published useful.

For a full understanding of your legal rights and the criteria for variations, refer to the Child Support Act 1991, which sets out the statutory basis for child maintenance arrangements in the UK. This ensures your application is grounded in the correct legal context and increases the likelihood of a fair outcome.

Common Grounds for Variation

When considering a change to a child maintenance arrangement through the Child Maintenance Service (CMS), it’s important to understand the common grounds that may justify a variation. These are specific circumstances in which the CMS may agree to adjust the amount you pay or receive, ensuring that the arrangement remains fair and reflects your current situation.

Typical Reasons for Requesting a Variation

Below are the most common grounds on which a variation might be granted:

1. Special Expenses

You can apply for a variation if you have certain special expenses related to your child or your circumstances. These might include costs such as travel expenses for seeing your child, expenses related to a child’s disability, or fees for boarding school. The CMS will consider whether these expenses are reasonable and necessary before deciding if they should affect your payments. For a detailed breakdown of what counts as special expenses and how they are assessed, see this guide on special expenses.

2. Changes in Income

Significant changes in income are another common reason for requesting a variation. If the paying parent’s income increases or decreases substantially – beyond the standard thresholds used by CMS – this can be grounds for a recalculation. For example, if you lose your job, receive a pay rise, or start earning extra from self-employment or investments, you may be eligible to request a variation. The CMS will require evidence of these changes, such as payslips or tax returns, to reassess the payment amount.

3. Shared Care Arrangements

If the way you and the other parent share care of your child has changed, this can affect the maintenance calculation. More frequent overnight stays with the paying parent, for example, may reduce the amount payable. The CMS considers the number of nights the child spends with each parent when working out payments. For further guidance, see information on shared care arrangements and how these may impact your case. You can also learn more about child arrangements and their role in maintenance decisions.

4. Income from Assets

If the paying parent has significant assets – such as property, savings, or investments – that are not reflected in their reported income, the CMS may take these into account when calculating maintenance. This ensures that the calculation is fair and that the child receives appropriate support, even if the parent’s regular income is low but they hold substantial wealth.

5. Other Relevant Circumstances

Other factors may also be considered, such as paying debts related to the former relationship or supporting other children. Each case is assessed individually, and the CMS will look at the specific details and evidence provided.

How These Grounds Affect Payment Calculations

When you apply for a variation, the CMS reviews your situation and any evidence you provide. If your application is successful, your child maintenance payments may increase or decrease depending on the circumstances. For example:

  • If you have proven special expenses, your payments may be reduced to account for these costs.
  • If your income has increased significantly, your payments may go up to reflect your greater ability to pay.
  • If you share care more equally, your payments may be lowered.

It’s important to provide clear, up-to-date evidence to support your application. This could include receipts, bank statements, or a written agreement about child arrangements.

For more comprehensive legal information on the grounds for variation, including special expenses and asset-related cases, see Variation of child maintenance on the grounds of assets | News | LexisNexis.

Understanding these grounds can help you decide whether to apply for a variation and what information you’ll need to provide. If your circumstances have changed, it’s worth reviewing your current arrangement and considering if a variation could help ensure your child maintenance payments are fair and appropriate.

Special Expenses

Special Expenses

Special expenses are certain costs that a parent can ask the Child Maintenance Service (CMS) to consider when requesting a variation to their child maintenance payments. If you are paying child maintenance and face significant costs directly related to your child, you may be able to apply for a variation so these expenses are taken into account. This can help ensure that your payments are fair and reflect your actual financial situation.

To qualify as a special expense, the cost must be necessary and directly linked to the child or the circumstances of the child maintenance arrangement. The CMS has strict guidelines about what counts as a special expense, and you will need to provide evidence to support your claim.

Common Types of Special Expenses

Some of the most common special expenses that may justify a variation include:

  • School Fees: If you pay fees for your child to attend a private school, you can ask the CMS to consider these costs. The rules around this can be complex, particularly in Wales, where the School Funding (Wales) Regulations 2010 set out specific requirements regarding educational costs. You will need to provide documentation, such as invoices or receipts, to prove the amount you pay.
  • Medical Expenses: Costs for medical or dental treatment, or for caring for a disabled child, may also be considered. This includes ongoing therapies, specialist equipment, or medicines not covered by the NHS. For further details about what might qualify and how these costs can impact your finances, see this resource on medical expenses.
  • Travel Costs: If you need to travel to see your child, such as when parents live far apart, the CMS may take into account reasonable travel expenses. This can include the cost of petrol, train tickets, or even overnight accommodation if needed for contact visits.
  • Repaying Debts from the Relationship: In some cases, if you are repaying debts that were jointly incurred for the benefit of the child or the family, these repayments may be considered special expenses.

Applying for a Variation Based on Special Expenses

To apply for a variation on the grounds of special expenses, you will need to submit a formal request to the CMS and provide clear evidence of the costs involved. This could include receipts, invoices, bank statements, or official correspondence. The CMS will review your application and decide if the expenses meet their criteria.

If your application is successful, your regular child maintenance payments may be reduced to reflect the special expenses you are paying. However, the CMS will only allow expenses that are reasonable, necessary, and directly related to the child.

For a comprehensive overview of the rules and legal background on this subject, you can read more about special expenses and the grounds for varying child maintenance payments.

Understanding what counts as a special expense and how to present your case can make a significant difference in ensuring your child maintenance arrangement is fair and manageable. If you are unsure whether your costs qualify, you can find further guidance on special expenses and how to apply for a variation.

Changes in Income or Financial Circumstances

Changes in Income or Financial Circumstances

A significant change in income or financial circumstances is one of the most common reasons to request a variation of a child maintenance arrangement through the Child Maintenance Service (CMS). The law recognises that parents’ financial situations can change unexpectedly, and maintenance payments should reflect these changes to remain fair for everyone involved.

What Counts as a Significant Change?

A “significant change” typically means a substantial shift in your financial position that affects your ability to pay, or the amount you should pay, in child maintenance. Examples include:

  • Losing your job: If you become unemployed, your income may drop considerably, making it difficult to keep up with current maintenance payments.
  • Reduced working hours: If your employer reduces your hours, or you have to take on a lower-paid job, your earnings may decrease enough to justify a change in payments.
  • Increased earnings: If you receive a pay rise, bonus, or promotion, your increased income may mean you are expected to contribute more towards your child’s upbringing.
  • Other financial changes: This could include receiving a lump sum (like an inheritance), starting to receive benefits, or facing new financial commitments, such as supporting another child.

The CMS uses specific rules to decide when a change in income is significant. Generally, a variation can be considered if your gross weekly income changes by at least 25% from the amount previously used in the calculation. This threshold helps prevent minor fluctuations from triggering constant recalculations.

How to Apply for a Variation

If you experience a significant change in your income or financial circumstances, you can apply to the CMS for a variation. You will need to provide evidence, such as payslips, redundancy letters, or proof of new income. The CMS will review your case and decide if an adjustment is appropriate based on the information you provide.

For a detailed explanation of how financial changes can affect maintenance orders, you may find it helpful to review the legal commentary on the Variation of Maintenance Orders (Variation of Maintenance Orders Act 1987). This resource covers the grounds and procedures for varying or revoking maintenance orders in depth.

You can also learn more about how the CMS considers changes in financial circumstances, including what types of evidence are required and how decisions are made.

Practical Advice

  • Act promptly: If your income changes, inform the CMS as soon as possible. Delays may result in arrears or overpayments.
  • Keep records: Gather and keep all relevant documents about your income and financial situation. This makes the variation process smoother and helps support your case.
  • Understand your rights: Both the paying parent and the receiving parent can request a variation if circumstances change.

Understanding your options and the rules around changes in income can help ensure your child maintenance arrangement remains fair and manageable for everyone involved.

Shared Care and Child Arrangements

Shared Care and Child Arrangements

Shared care refers to situations where a child spends time living with both parents, rather than staying with just one. These arrangements can have a direct impact on child maintenance payments calculated by the Child Maintenance Service (CMS). The amount of time a child spends with each parent is taken into account when working out how much maintenance should be paid.

When parents share care, the CMS reduces the maintenance amount according to the number of nights the child stays with the paying parent. For example, if a child stays overnight with the paying parent at least 52 nights a year, the maintenance payment may be reduced. The more nights the child spends, the greater the reduction. This adjustment is designed to reflect the shared responsibility of both parents for the child’s living costs.

If your shared care arrangement changes – such as your child staying more or fewer nights with you – this can be a valid ground to request a variation in your maintenance payments. For instance, if you start having your child overnight more frequently, or if the arrangement shifts so that one parent takes on more day-to-day care, it’s important to notify the CMS. Accurate records, such as calendars or written agreements, can help support your request.

Understanding the details of child arrangements is essential, as these legal agreements set out where and with whom a child lives, as well as how much time they spend with each parent. Changes to these arrangements – whether formal or informal – can affect your maintenance obligations.

If you are considering changing your shared care agreement, or if circumstances have already changed, you may find it helpful to learn more about the Variation of Child Arrangements. This resource outlines the process involved in altering existing arrangements and what steps you may need to take.

In summary, changes in shared care and child arrangements can significantly impact child maintenance payments. If your situation changes, it’s important to inform the CMS promptly and provide evidence of the new arrangement. This ensures that payments remain fair and reflect your current level of care for your child.

Evidence Required to Support a Variation Application

When applying to vary a child maintenance arrangement through the Child Maintenance Service (CMS), you must provide clear and reliable evidence to support your request. The type of evidence required depends on both your eligibility to apply and the specific grounds for variation you are relying on. Supplying the correct documents helps the CMS assess your circumstances accurately and ensures your application is processed without unnecessary delays.

Why Evidence Matters

The CMS bases its decisions on the information you provide. Incomplete, outdated, or inaccurate evidence can lead to your application being refused or delayed. It is important to submit up-to-date documents that clearly demonstrate your financial situation or the specific change in circumstances you are claiming.

Types of Evidence Needed

Below are common types of evidence you may need to provide, depending on your reason for requesting a variation:

1. Proof of Income and Financial Circumstances

If your application is based on a change in income, you will need to submit recent financial documents. Examples include:

  • Recent payslips (usually covering the last three months)
  • P60 forms or annual tax returns
  • Bank statements
  • Letters from your employer confirming changes in salary or employment status

For more detailed guidance on what counts as acceptable financial documents, see the LexisNexis resource on variation of financial orders.

2. Evidence of Special Expenses

If you are asking for a variation due to special expenses (such as costs related to a child’s disability, travel expenses for contact, or school fees), you should provide:

  • Receipts or invoices for relevant expenses
  • Written confirmation from service providers (e.g. schools, medical professionals)
  • Travel tickets or mileage logs

3. Court Orders

If your circumstances have changed because of a court decision – such as a new arrangement for child contact or a financial order – you must provide a copy of the relevant court order. This helps the CMS understand the legal context and ensures your application reflects any binding decisions made by the court.

4. Other Supporting Documents

Depending on your situation, you might also need to submit:

  • Letters from benefits agencies if your benefits have changed
  • Documentation of self-employment income or business accounts
  • Proof of shared care arrangements, such as calendars or written agreements

Practical Advice

  • Always provide copies rather than original documents, unless specifically requested.
  • Ensure all evidence is up to date – outdated documents may not be accepted.
  • If any documents are not in English, you may need to provide a certified translation.
  • Clearly label and organise your evidence to make it easy for the CMS to review.

Common Questions

What happens if I cannot provide all the evidence?
If you are missing certain documents, explain why in your application and provide as much alternative evidence as possible. The CMS may contact you for further information.

How current should my financial documents be?
Generally, documents should be no more than three months old to reflect your current circumstances accurately.

Can I submit digital copies?
The CMS often accepts scanned or digital copies, but check their current guidance before submitting your application.

Providing thorough and accurate evidence is key to a successful variation application. For more information on the types of documents you may need, see further guidance on financial documents and court orders. If you are unsure which documents to submit, consider seeking advice from a legal professional or contacting the CMS directly.

What specific evidence do I need for my variation application?

How a Variation Affects Maintenance Payments

When a variation to a child maintenance arrangement is approved by the Child Maintenance Service (CMS), it can directly change the amount that needs to be paid. The outcome depends on the specific circumstances and the evidence provided during your application.

A successful variation may result in one of three outcomes:

  • Payments increase: If the evidence shows, for example, that the paying parent has extra income not previously included or receives certain benefits, the CMS may decide that a higher payment is appropriate.
  • Payments decrease: If the paying parent has unavoidable extra costs – such as supporting other children, high travel expenses related to contact, or significant debts related to the child – the CMS may reduce the maintenance amount.
  • Payments stay the same: Sometimes, after reviewing the evidence, the CMS may determine that the existing arrangement is fair and no change is needed.

It’s important to understand these possible effects before you apply for a variation. Applying without strong evidence or a clear understanding of the rules could mean your payments remain unchanged, or in some cases, even increase unexpectedly. Reviewing your financial situation carefully and gathering all relevant documentation can help you make an informed decision.

The process and impact of a variation are governed by specific legal rules set out in the Child Support Act 1991. This legislation outlines how maintenance is assessed and the circumstances under which variations can be made. For more insight into how the Family Justice System interacts with maintenance payments and supports children’s welfare, the Family Justice System report provides useful background.

Before submitting an application, you may want to explore more about how variations affect payments to understand the process, timelines, and what to expect once your request is considered. This can help you decide if a variation is the right step for your situation.

Related Financial Considerations and Support

When considering a variation to your child maintenance arrangement, it’s important to look at your wider financial situation, especially if you’re going through separation or divorce. Variations to child maintenance payments often intersect with other financial orders and support options, so understanding these connections can help you make informed decisions for your family’s future.

Variations and Other Financial Orders

A child maintenance variation through the Child Maintenance Service (CMS) is just one aspect of the financial arrangements that may be put in place during or after separation. In many cases, parents may also have financial orders during divorce, which can cover things like property, pensions, and lump sum payments. While CMS variations deal specifically with ongoing child maintenance, financial orders can provide a broader financial framework, especially if you’re dividing assets or agreeing on spousal maintenance.

For a deeper understanding of how these orders can be changed or updated, you may wish to read about Financial Orders, which explains the legal grounds and procedures for varying existing arrangements. This can be particularly relevant if your financial situation changes significantly after the original order was made.

Other Support Options for Parents

Child maintenance is just one form of support available to parents. If you’re struggling to agree on payments or need help navigating the process, the Child Maintenance Service offers practical guidance on how to apply, challenge decisions, and ensure you receive the right amount. It’s a good idea to explore all the support options available, including benefits and local authority services, to make sure your children’s needs are met.

Housing and Work Arrangements

Changes to your financial circumstances – such as a variation in maintenance payments – can also affect your housing and employment situation. If you’re a single parent or your living arrangements are changing, you may be eligible for housing assistance for single parents. This can include help with finding suitable accommodation or understanding your rights under the Housing Act 1996.

Balancing work and childcare is another important consideration. If your responsibilities have changed, you might benefit from exploring work accommodations for parents, such as flexible working arrangements or adjustments to your job role. These can make it easier to manage your finances and caregiving duties alongside any changes to maintenance payments.


By considering variations in the broader context of financial orders, housing, and employment, you can ensure that your child maintenance arrangements truly reflect your family’s needs. Taking a holistic approach helps you plan for long-term stability and wellbeing, both for you and your children.

Next Steps: Applying for a Variation

Once you’ve confirmed your eligibility and identified valid grounds for a variation, the next step is to begin the formal application process through the Child Maintenance Service (CMS). It’s important to follow the correct procedure to ensure your request is considered promptly and fairly.

How to Start Your Application

To apply for a variation, you’ll need to contact the CMS and provide specific details about why you believe the current arrangement should be changed. This usually involves filling out a variation application form, where you’ll be asked to explain your reasons – such as a significant change in income, new expenses related to the child’s needs, or evidence of unreported income.

Submitting Required Evidence

Supporting evidence is crucial for a successful application. This may include recent payslips, bank statements, proof of additional costs (like school fees or medical expenses), or documentation of any changes in your financial circumstances. Providing clear and thorough evidence helps the CMS make an informed decision and can prevent delays.

Procedure and Guidance

Following the official process is essential. Incomplete applications or missing documents can result in your request being delayed or rejected.
