Variations explained: a guide for receiving parents
Updated 27 October 2023
Applies to England, Scotland and Wales
Information for parents who receive child maintenance
You may have heard different terms used to describe the parents in a child maintenance case.
In child support law:
- the parent who receives child maintenance is known as the 鈥榩arent with care鈥� - we call them the 鈥榬eceiving parent鈥�
- the parent who pays child maintenance is known as the 鈥榥on-resident parent鈥� - we call them the 鈥榩aying parent鈥�
Do we take any other information into account when we work out child maintenance?
Yes, but you or the paying parent have to ask us first. We call this 鈥榓pplying for a variation鈥�.
You (or the paying parent) can ask us to look at certain types of the paying parent鈥檚 income that are not included in the main rules we use to work out child maintenance.
This is called 鈥榓dditional income鈥�. It can increase the paying parent鈥檚 gross income figure that we use when we work out child maintenance.
The paying parent can ask us to take into account certain expenses they pay. These are called 鈥榮pecial expenses鈥� and can reduce the paying parent鈥檚 gross income figure that we use when we work out child maintenance.
You or the paying parent can apply for a variation at any time, either before or after a child maintenance amount is worked out.
A paying parent鈥檚 additional income you can ask us to consider
You can apply for a variation for:
- 鈥榰nearned鈥� income 鈥� for example, rental income the paying parent gets from property or land, or dividends and interest from savings and investments. This type of income must be at least 拢2,500 a year
- 鈥榥otional income from assets鈥� - this is income that we can work out the paying parent could get based on certain types of assets that they own if the asset鈥檚 total value is 拢31,250 or more
- 鈥榚arned鈥� income 鈥� this is when the paying parent is getting benefits (and qualifies to pay Flat rate child maintenance) but also has gross income from a pension, employment or self- employment. This type of income must be at least 拢100 a week
- 鈥榙iversion鈥� of income 鈥� this is when you think the paying parent is controlling the amount of income they get by diverting it to another person or another purpose, which means it is not being included in the figure we use to work out child maintenance
Expenses a paying parent can ask us to consider
A paying parent can apply for a 鈥榮pecial expenses variation鈥� for:
- the cost of keeping up regular contact with a child or children that qualify for child maintenance 鈥� for example, the cost of fuel to travel between the home of the paying parent and the child that qualifies for child maintenance (must be at least 拢10 a week)
- costs connected with supporting a child with a disability or a long-term illness
- repaying debts from a former relationship 鈥� for example, the paying parent is paying a car loan for a car the receiving parent has kept (must be at least 拢10 a week)
- boarding school fees for a child or children that qualify for child maintenance 鈥� but only the everyday living costs or 鈥榖oarding鈥� part of the fees (must be at least 拢10 a week)
- making payments on a mortgage, loan or insurance policy for the home that the paying parent and receiving parent used to share 鈥� the receiving parent and the child or children must still live in the home, and the paying parent must have no legal or 鈥榚quitable鈥� interest in it (must be at least 拢10 a week)
A paying parent can鈥檛 ask us to take special expenses into account if their gross income is less than 拢7 a week or if they are getting benefits.
When either parent applies for a variation, we share the information they give us with the other parent. This allows us to get information from everyone involved before we make a decision.
We will also use other sources of information such as Companies House.
How to apply
You can apply for a variation at any time.
You can make an application for a variation over the phone in most cases. However, if the application is complicated we may ask you to apply in writing, using an application form.
It is very important that the application contains as much information as possible. The person applying must say why they are applying for a variation, or give us enough information for us to be able to see why they are applying. The only reasons for applying for a variation are given above and are set out in child support law.
