PRO SE CHILD SUPPORT MODIFICATION GUIDE

WHAT IS A CHILD SUPPORT MODIFICATION?
A modification is a change to an existing child support order. Either parent can request a modification if there has been a significant change in circumstances.
You can request:
- An increase in child support

☐ Disability affecting ability to work
☐ Incarceration
☐ Retirement
Changes Involving the Child:
☐ Child's medical expenses increased significantly
☐ Child's educational costs increased
☐ Child has special needs

Other Changes:
☐ Paying parent has new children to support
☐ Receiving parent remarried (not always relevant)
