Child maintenance is essentially a way to ensure your child's everyday needs are met when they're living with just one parent. This is a requirement whether you've split from the other parent or never officially been together.
Keep in mind that child maintenance focusses on financial support and both parents have a role in covering their child's expenses, even if they're not always around for the day-to-day. Arrangements about spending quality time with your child are handled separately.
It's essential to have a child maintenance agreement if your child is under 16, and this extends to 20 if they're still in full-time education.
You’ll need details of the following for the parent who’ll be paying:
- their income, including State Pension
- any benefits they get
- the number of nights your child stays with them
You can access the governments' child maintenance calculator to give you an estimate.
