Variations explained: a guide for paying parents

Updated 27 October 2023

Applies to England, Scotland and Wales

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 receiving parent have to ask us first. We call this 鈥榓pplying for a variation鈥�.

You can ask us to take into account certain expenses you pay. These are called 鈥榮pecial expenses鈥� and can reduce the gross income figure that we use when we work out child maintenance.

You (or the receiving parent) can also ask us to look at certain types of your income that are not included in the main rules that we use when working out child maintenance.

This is called 鈥榓dditional income鈥� and can increase the gross income figure that we use when we work out child maintenance.

You or the receiving parent can apply for a variation at any time, either before or after a child maintenance amount is worked out.

Expenses you can ask us to consider

You can apply for a special expenses variation for:

  • the cost of keeping up regular contact with a child or children that you pay child maintenance for 鈥� for example, the cost of fuel to travel between your home and the child鈥檚 home (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, if you are 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 you pay child maintenance for 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 you and the receiving parent used to share 鈥� the receiving parent and the child or children must still live in the home, and you must have no legal or 鈥榚quitable鈥� interest in it (must be at least 拢10 a week)

You can鈥檛 ask us to take special expenses into account if your gross income is less than 拢7 a week or if you are getting benefits.

Other types of your income we can be asked to consider

An 鈥榓dditional income variation鈥� application can be made for:

  • 鈥榰nearned鈥� income 鈥� such as rental income you get 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 you could get based on certain types of assets that you may own if the asset鈥檚 total value is 拢31,250 or more
  • 鈥榚arned鈥� income 鈥� this is when you are getting benefits (and qualify to pay Flat rate child maintenance) but you also have gross income from a pension, employment or self employment. This income must be at least 拢100 a week
  • 鈥榙iversion鈥� of income 鈥� this is when you may be controlling the amount of income you get by diverting it to another person or other purpose, which means it is not being included in the figure we use to work out child maintenance

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, on an application form.

It鈥檚 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.
