Modifying Child Support After Job Loss, Disability or Incarceration in Colorado
Colorado child support does not drop on its own after a job loss, disability or incarceration. You must file, the change starts at the filing date, and no potential income is imputed to a parent sentenced to 180 days or more.
Can you reduce child support after a job loss in Colorado?
Yes, if the change is substantial and continuing and you file; the modification takes effect from the filing date, not from the date you lost the job (C.R.S. 14-10-122(1)(d)). The court may modify installments due between the filing and the order even if the circumstances that justified the modification no longer exist when the order is entered.
Will Colorado use potential income if you quit or earn less?
If a parent is voluntarily unemployed or underemployed, child support must be calculated on potential income, except that it must not be determined for a parent who is physically or mentally incapacitated, a parent caring for a child under the age of twenty-four months for whom the parents owe a joint legal responsibility, or an incarcerated parent sentenced to one hundred eighty days or more (C.R.S. 14-10-115(5)(a)).
Can Colorado child support be reduced while incarcerated?
A determination of potential income must not be made for an incarcerated parent sentenced to 180 days or more, so the order is figured on actual income. The order does not change by itself: you have to file, and the effective date is the filing date. Federal rules also bar treating incarceration as voluntary unemployment (45 CFR 302.56(c)(3)).
What if a parent with past-due support is unemployed?
If a noncustodial parent who owes past-due support is unemployed and not incapacitated and has an obligation of support to a child receiving public assistance under part 7 of article 2 of title 26, the court or the delegate child support enforcement unit may order the parent to pay under a court-approved plan or to participate in work activities such as employment, job search, community service or vocational training (14-10-115(5)(a)(II)).
Is there a low-income adjustment?
Yes. The guidelines include a low-income adjustment and a minimum monthly order for obligors with very low adjusted gross income, and HB25-1159 expanded the income range for the low-income adjustment (HB25-1159). Check the figures in the Colorado child support calculator at filing, because the schedule was updated.
Who is excluded from potential income?
| Parent | Rule (14-10-115(5)(a)(I)) |
|---|---|
| A parent who is physically or mentally incapacitated | No potential income determination |
| A parent caring for a child under 24 months for whom the parents owe a joint legal responsibility | No potential income determination |
| An incarcerated parent sentenced to 180 days or more | No potential income determination |
How much does a late filing cost? An example
Say a parent loses a job on January 15 and files on March 1. The new order takes effect March 1, so the installments for the period before filing stay at the old amount:
| Reduction the court later orders | Relief lost for the 1.5 months before filing |
|---|---|
| $300 a month lower | $450 |
| $500 a month lower | $750 |
| $800 a month lower | $1,200 |
File as soon as the income drops.
What proof helps?
- The termination or layoff notice and your last pay stub.
- Unemployment or disability award letters.
- Your job-search record.
- Medical records if the cause is disability.
- For incarceration, the sentence showing 180 days or more.
What should you do first?
- File the motion now: the effective date is the filing date.
- Keep paying what you can: unpaid payments are final money judgments with interest (see the Colorado interest rate).
- Check the numbers in the Colorado child support modification calculator.
