Use the Child Maintenance Service or Child Support Agency (CSA)

How to apply

The Child Support Agency (CSA) now only handles existing cases. New claims are dealt with by the Child Maintenance Service.

Make a new arrangement

Your first step is to contact Child Maintenance Options.

They’ll talk with you about arrangement options. If you decide to use the Child Maintenance Service, they’ll give you a reference number and explain how to apply.

Child Maintenance Options cannot discuss existing CSA or Child Maintenance Service cases.

If you apply to the Child Maintenance Service

You’ll need to give information about you and your family, for example:

  • details about the child you’re applying for - including the full names of their mother and father
  • your National Insurance number
  • your bank account details, if the Child Maintenance Service needs to collect and pass on payments


The application fee is £20.

You will not have to pay this if you’re:

  • a victim of domestic violence
  • under 19 years of age
  • in Northern Ireland

How your information is used

Your information is used to set up and manage child maintenance payments, and sometimes to try and find the paying parent.

Your name and address will not be given out to anyone unless ordered to by a court, but information might be shared with other government organisations, debt collection agencies or the courts.

If the Child Maintenance Service or CSA cannot get the information from either parent, they might ask others, for example:

  • the ‘paying’ parent’s employer
  • government organisations like Jobcentre Plus
  • prison services or local councils
  • the paying parent’s bank or building society

The receiving parent has main day-to-day care of the child. The paying parent does not have main day-to-day care.

Read more about how the Child Maintenance Service or the CSA use your information.

How long it takes

Most child maintenance cases are set up within a month. Sometimes this can take longer if there’s a problem with contacting the paying parent.

The first child maintenance payment is usually made within 6 weeks of making payment arrangements.

If the contact details for the paying parent are not known, the service will try to find them - but if they cannot, the receiving parent cannot open a case.
