You're in — here's your guide.
Read it top to bottom. Find your state. Then do Step 1 of the action plan on page 4. That's all it takes.
You're probably paying too much. Here's how most dads find out.
— Marcus, Ohio
Your income dropped. Or your hours got cut. Or you started spending more time with your kids. Or the original order was set years ago when the rules were different.
Any one of those things — in most states — gives you the legal right to ask for a lower payment. But the court won't come to you. You have to go to them. And when you do file, they only go back to the date you filed. Not the date your situation changed.
The table on the next page tells you — for your state — the exact income drop you need to qualify, whether you can do this without court, what the filing fee is, and how long it takes. This information is public record. It's just buried in state websites no one reads.
We read them for you. All 51. And put it in one table.

|---|---|---|---|---|---|---|
| Alabama AL |
10% ✅ Easy |
3 years | ✔ Free option | 60–120 days | ~$100–200 | Alabama uses a '10% or $50/mo' rule — either threshold triggers eligibility. |
| Alaska AK |
15% ⚠️ Moderate |
3 years | ✔ Free option | 60–90 days | ~$150–250 | Alaska is one of 7 states using pure % of obligor income — your income alone drives the number. |
| Arizona AZ |
15% ⚠️ Moderate |
3 years | ✔ Free option | 60–120 days | ~$102 (Maricopa Co.) | AZ requires 15% change OR substantial change in parenting time. File on the same day either happens. |
| Arkansas AR |
20% or $100/mo 🔶 Harder |
3 years | ✔ Free option | 60–120 days | ~$165 | AR uses a variable percentage model — higher earners see a lower base percentage applied. |

15% or $50/mo ⚠️ Moderate |

✅ Do This Today — 5-Step Action Plan
You now know what your state requires. Here's exactly what to do next — in order.
- Find your state in the table above. Look at the Threshold column. Is your income drop bigger than that percentage? If yes — you likely qualify. If you're at the 3-year review window — you also qualify. Move to Step 2.
- Check the "Free Admin?" column for your state. If your state shows ✔ Free option — start with the administrative route. It's free, faster, and you never have to set foot in a courtroom. Call your state's child support enforcement agency this week.
- Gather your documents — today, not next week. You'll need: your 3 most recent pay stubs, last 2 years' tax returns, and your current child support order. If you're unemployed: layoff letter + any unemployment payment documentation.
- File on the earliest possible date. Remember: courts only go back to your filing date — not the date your income dropped. Every week you wait is money you cannot recover. File this week if you can.
- Track every hearing date and deadline in writing. Most modifications fail not because of the facts — but because dads miss a deadline or don't show up. Write every date on your calendar. Set phone reminders. Treat it like a job interview.
