It is very upsetting to believe that the other parent is not being honest about their income, especially where this affects the financial support your child receives. Many parents feel powerless when child maintenance payments seem unrealistically low, particularly where a business or company structure is involved. Understanding how the law approaches hidden income can help you see what options may be available.
Understanding the issue or context
Child maintenance is intended to ensure that children are financially supported by both parents. Problems often arise where one parent is self-employed, paid through a company, or involved in a business with a new partner.
In these situations, income can appear artificially low on paper. Parents commonly report that the paying parent declares minimal earnings while still enjoying a higher standard of living, supported by company funds, dividends, or a partner’s business.
This can feel deeply unfair, particularly where the child receives only a very small weekly amount that does not reflect the other parent’s true financial position.
The legal rules or framework
In the UK, child maintenance is usually dealt with through the Child Maintenance Service (CMS). The CMS primarily bases maintenance calculations on income information provided by HMRC.
However, the system recognises that declared income does not always reflect reality. Where there is evidence that a paying parent has unreported income, diverted income, or income hidden within a company, the receiving parent can ask the CMS to look more closely.
This is known as applying for a variation. Variations allow the CMS to take into account additional income, assets, or situations where income is being deliberately reduced to avoid paying maintenance.
If a paying parent is a company director or controls a business, the CMS may consider income such as dividends, retained profits, or benefits derived from the business, depending on the evidence available.
Practical steps to take
If you believe your ex is hiding income, the following steps can help you move forward:
- Request a variation through the CMS
This is the formal route for challenging an unrealistically low maintenance assessment. - Gather evidence carefully
Useful evidence may include company details, lifestyle indicators, social media, public records, or information showing control of a business. - Focus on facts, not assumptions
The CMS will not act on suspicion alone. Clear, objective information is important. - Keep records of payments and communications
This helps show the history of maintenance and any inconsistencies. - Seek legal clarity if the situation is complex
Where company structures or significant assets are involved, legal advice can help you understand whether further action is realistic.
Common pitfalls to avoid
Parents often encounter difficulties by:
- Relying only on verbal claims or suspicion
- Expecting the CMS to investigate without evidence
- Confusing a partner’s income with the paying parent’s income
- Becoming discouraged when the process takes time
A focused, evidence-based approach is more likely to lead to progress.
Frequently Asked Questions
Can the CMS investigate hidden income?
Yes. The CMS can look into additional or diverted income through the variation process.
Does owning a company matter?
It can. Company ownership or control may be relevant if income is being sheltered.
Can my ex’s partner’s income be included?
Generally no, unless it is directly linked to your ex’s income or benefits.
What if the CMS refuses to change the amount?
There may be review or appeal options, depending on the decision.
Is £12 a week normal?
Low payments can occur, but they should reflect genuine declared income.
Should I get legal advice?
Yes, especially where business interests or deliberate concealment are suspected.
