Colorado Child Support Modification LAwyers
A prenuptial agreement in Colorado is a written contract two people sign before marriage to decide how property, debt, and spousal support would be handled if the marriage ends. A postnuptial agreement does the same work after the wedding. Both are governed by the same Colorado statute, the Uniform Premarital and Marital Agreements Act, and both must meet specific signing, disclosure, and counsel-access requirements to hold up in court.
Whether you are protecting a business, separate property brought into the marriage, future inheritance, or one spouse’s career investments, the agreement is only as strong as the process behind it. A document that looks airtight on paper can be set aside if either spouse was rushed into signing, denied access to a lawyer, or kept in the dark about the other side’s finances. Our Colorado family law team builds these agreements to be honest, balanced, and enforceable, with the documentation that holds up if anyone later tries to challenge them.

When Colorado courts will modify child support
Colorado allows modification of child support under C.R.S. § 14-10-122[1] when there has been a substantial and continuing change in circumstances since the existing order. The statute does not require a specific dollar threshold by itself. Courts look at whether the change is real, durable, and large enough to make the current order unfair under today’s facts.
A change is “substantial and continuing” when it is significant in size and reasonably expected to last. Short-term swings, like one slow month at work or a temporary bonus, usually do not qualify. A new job, an extended layoff, a serious medical condition, or a permanent shift in parenting time normally does.
The most common triggers we see in Colorado modification cases include:
- Income change for either parent. Job loss, a raise, a new position, business income fluctuation, retirement, or disability.
- Parenting time changes. A real, sustained shift in overnights between households, since overnights drive the guideline calculation.
- Medical or extraordinary expenses. New uninsured medical costs, special education needs, or major childcare changes.
- Emancipation or aging out. A child turning 19 or otherwise emancipating under Colorado law can change support owed for remaining children.
- A new child support obligation. When a parent now owes support for another child, the new math feeds into the existing guideline calculation.
The 10% threshold and why it matters
Colorado layers a practical screening test on top of the “substantial and continuing” standard. If running today’s guideline calculation would change the monthly support amount by less than 10%, the court has discretion to find that no substantial change has occurred. If the calculation shifts the number by 10% or more, the change is generally treated as substantial enough to revisit the order.
This is not a guarantee in either direction. A 12% swing is not automatic, and a 7% swing is not automatically dead. We run the math before we file, so you know whether you have a case worth filing or a motion the court is likely to deny.
How to file a motion to modify in Colorado
Modification is filed in the same court that entered the original support order, because that court retains continuing jurisdiction over the case. You do not open a new case. You file a motion to modify under the existing case number.
The basic sequence looks like this:
- Gather current financial information. Recent pay stubs, the last two tax returns, proof of health insurance premiums, work-related childcare costs, and documentation of the change you are asking the court to recognize.
- Update your Sworn Financial Statement. Both parents file current Sworn Financial Statements (JDF 1111) and Child Support Worksheets reflecting today’s numbers.
- File the motion and supporting documents. The motion identifies the change, attaches the new calculation, and states the relief you want.
- Serve the other parent. Service is required for the motion to proceed. Personal service or service through counsel both work, depending on how the original case ended.
- Attend a hearing or resolve by agreement. Many modification cases settle by stipulation once both sides see the same numbers. Others go to a hearing where the court hears evidence and rules.
Retroactive modification only goes back to the filing date
This is one of the most important rules in Colorado modification, and it is the rule that costs parents the most money when they wait. Under § 14-10-122, the court can modify support only for installments coming due after the motion is filed. The court cannot wipe out support that already accrued before the filing date.
In plain terms: if your income drops in January but you wait until July to file, the support that came due January through June is still owed. The court can adjust July forward, but it cannot retroactively forgive the first six months. Filing early is how you protect yourself from carrying support obligations that no longer match your real income.
Medical support and add-on expenses
Medical support, including health insurance and uninsured medical costs, is treated slightly differently from the base support number. A court can add or correct medical support provisions even when there is no broader substantial change, because Colorado requires medical support to be addressed in every order. If your current order is silent on medical support or no longer reflects who carries insurance, that alone may justify a motion.
Add-on expenses like work-related childcare, extraordinary medical costs, and certain education expenses are also reviewed during a modification. Documentation matters here. Courts want receipts, statements, and proof of payment, not estimates from memory.

Stipulated modifications and avoiding a contested hearing
You and your co-parent can agree to modify support without a full contested fight. A stipulated modification is a written agreement on the new support number that both parents sign and the court approves. It is faster, less expensive, and more enforceable than a private handshake.
A stipulation only works if both parents are willing to share current income information and run the guideline calculation honestly. We use stipulations whenever the facts allow it. When the other side refuses to disclose, hides income, or stonewalls on parenting time data, we move to a contested process and let the court compel the documents.
When the other parent is hiding income
Self-employment, cash businesses, executive compensation, RSUs, equity grants, and bonus-heavy pay structures can all create opportunities for under-reporting. Colorado courts can impute income to a parent who is voluntarily underemployed, who refuses to provide documentation, or whose lifestyle does not match the income claimed.
We address these cases with documentation, subpoenas, careful review of tax returns and business records, and, where the numbers justify it, expert testimony. The goal is not to attack the other parent. The goal is to put the real income in front of the court so the guideline calculation reflects reality.
How Johnson Law Group handles Colorado child support modification
When you bring a modification matter to our team, we start with the math. We run the current Colorado guideline calculation against the existing order, then tell you on the first call whether you have a case worth filing. If the numbers justify a motion, we explain your projected new order, your timing exposure, and where the other side is likely to push back.
From there, we keep you in the loop through our client portal so you know where the case stands, what is owed when, and what the next step looks like. You should never have to call us to find out whether your motion was filed.
We handle modification cases across our Colorado offices, including matters that started in another county or another state. If your original order came out of a different jurisdiction and now needs modification here, we work through the registration and jurisdictional questions first. Colorado handles that under its version of the Uniform Interstate Family Support Act (UIFSA), and we sort it out before the substantive motion is filed.
Frequently Asked Questions
How long does a child support modification take in Colorado?
Timelines vary by county and complexity. A stipulated modification can finalize within a few weeks once both sides exchange financial documents. A contested modification that requires a hearing typically takes several months from filing to order, depending on the court’s calendar.
Can I stop paying child support if I lose my job?
No. You must continue paying the existing order until the court modifies it. Stopping unilaterally creates arrears with interest and can trigger enforcement consequences. The right move is to file a motion to modify as soon as possible so the court can adjust the order going forward.
Does my child support change automatically when my income changes?
No. Colorado does not adjust support automatically. The existing order remains in effect until a court enters a new one. If your income has dropped, the only way to lower your obligation is to file a motion to modify.
Can we just agree privately and skip court?
A private agreement does not change your court-ordered obligation. If you both agree to a new number, put it in a written stipulation and submit it to the court for approval. Until the court signs off, the original order controls.
What if the other parent and I share roughly equal parenting time?
Parenting time directly affects the guideline calculation. When overnights shift, the support number usually shifts with them. A real, sustained change in overnights is one of the most common reasons we see for modification.
How far back can the court modify?
The court can modify only forward from the date your motion is filed. Support that came due before that date stands as ordered, even if your circumstances changed earlier. This is why filing early matters.
