The government has set out a formula to help parents work out how child maintenance should be paid. Their online child maintenance calculator tool is a useful resource but does not deal with tricky situations - when you'll need specialist advice - but it does provide a useful benchmark.
There are three options for arranging child maintenance with your ex:
- A family based arrangement - you and your ex can make any arrangement you like for child maintenance provided you both agree. However, it will not be legally binding.
- The Child Maintenance Service (or CMS, which used to be called the CSA) - the government-run CMS can calculate child maintenance for you and your ex if you can't agree the amount yourselves and can also do the administration around the payments by collecting them and paying them over if required.
- Court - not only can court orders be used to turn voluntarily agreed arrangements into legally binding ones but the court can also deal with more complicated or unusual situations for example where the paying parent has a very high level of income, where school fees need to be paid and where either parent or the child lives abroad.
The interaction between child maintenance and other financial arrangements such as spousal maintenance can be tricky and it's important to get advice on the overall picture.
