Paying child support
How to pay child support
There are different ways to make child support payments.
Collecting child support
Choose a collection option
The person who will receive child support can choose how the paying parent pays them.
This is where you and the other parent make and receive payments directly between you. It’s for parents who don’t need much help from us to agree on a plan.
Child Support Collect
This is where we collect and transfer child support payments for you.
