PRO SE CHILD SUPPORT MODIFICATION GUIDE

A Step-by-Step Guide to Modifying Child Support Orders


IMPORTANT WARNINGS

DO NOT STOP PAYING CHILD SUPPORT while your modification is pending. Child support continues at the current amount until a judge changes it. Failure to pay can result in:
- Wage garnishment
- License suspension
- Contempt of court
- Jail time


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
- A decrease in child support
- Changes to payment terms


SECTION 1: DO YOU QUALIFY FOR A MODIFICATION?

Grounds for Modification

Most states require a "substantial change in circumstances." Check all that apply to your situation:

Income Changes:
☐ Job loss or unemployment
☐ Significant salary reduction (usually 15-20%+)
☐ New higher-paying job (for either parent)
☐ 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
☐ Child became emancipated
☐ Child's living arrangements changed
☐ Parenting time changed substantially

Other Changes:
☐ Paying parent has new children to support
☐ Receiving parent remarried (not always relevant)
☐ Health insurance availability changed
☐ 3+ years since last order (automatic review right in most states)

When You CANNOT Modify

☐ Temporary income reduction (short-term layoff)
☐ Voluntary unemployment (quit without good reason)
☐ Voluntary underemployment (took lower-paying job by choice)
☐ Remarriage income of new spouse (usually)

Percentage of Income Model (Some States):
- Percentage of paying parent's income

Most states have online child support calculators:
