Child Support in Colorado: How to Apply and Get Help

What has changed since June 2026

The Colorado Judicial Branch revised its child support modification instructions on July 13, 2026. If you need to change an order, use the current court instructions and forms, not old copies you saved. The court explains a 10% change test for many requests, along with an exception when an order lacks medical or dental support terms.

Colorado’s 2026 support-calculation changes are also in effect. The state updated its guideline schedule, low-income adjustment, and credit for parenting-time overnights. An existing order does not change by itself: ask the county office or court what steps apply to your case.

Where to start

Start with the question that matches your situation. A parent who has no order needs a different next step than a parent with a court order and missed payments. If safety is part of the situation, talk about safety before location, enforcement, or court notices are sent.

What Colorado Child Support Services can and cannot do

Colorado Child Support Services can help parents and caretakers with child support tasks. This includes locating a parent, establishing parentage, setting up child support and medical support orders, processing payments, enforcing orders, and helping with some requests to change an order.

Individual child support orders are managed by county child support offices. The county office that handles your case is usually the best place to ask about your file, notices, missing documents, payment questions, or enforcement status. Use the state county office finder if you need contact information.

Child Support Services is not your private lawyer. The office works to establish and enforce support under the law. It usually does not handle divorce, custody, parenting time, protection orders, or full family-law representation. For those issues, you may need legal aid, a court self-help center, a lawyer, or ASMOM’s legal help guide.

How to apply for child support in Colorado

Colorado says county child support offices require an application to begin a child support case, and applying online is the fastest and easiest method. There is no application fee for child support services. A printable application may also be available if online access is hard.

1. Start the application. Use the online application or ask your county office for paper options.
2. Give information about both parents. Include names, birth dates, addresses, employers, Social Security numbers if known, old phone numbers, relatives, and past locations.
3. Explain the child’s living situation. Say who the child lives with, whether there is an existing court order, and whether safety concerns exist.
4. Upload or mail documents. Add birth certificates, court orders, income records, child care bills, and health insurance proof when you have them.
5. Respond to county requests. If the caseworker asks for more information, answer as soon as you can. Ask for help if you do not understand a notice.

You can also review ASMOM’s national child support hub if you need a broader overview before applying.

Online form tip: Colorado says you can leave fields blank when you do not know the answer. If you create an online account, the application can be saved for 60 days. If you use the printable application, send it to your county office and keep a copy and the mailing date. Application help is free, but private legal representation and some separate court filings may cost money.

After submitting: Save your application number or submission receipt. Ask which county has the case, whether a parentage step or legal notice is needed, and how the worker will contact you safely. If you move or change numbers, tell the office using the contact method you agreed is safe.

Information to gather before you apply

You do not need every item on this list to get started. Colorado says to provide as much information as possible. Still, gathering documents early can reduce delays.

Keep a paper folder and a phone folder with photos of key records. Save copies of any forms you send.

How Colorado calculates child support

Colorado uses child support guidelines set in state law. The formula can consider both parents’ gross income, the number of children, parenting time, child care costs, health insurance, and other allowed factors. The state’s calculating payments page explains the basic factors.

Use the Colorado Judicial Branch calculator page to estimate support and prepare worksheets. The worksheet helps show the calculation used for court, but an estimate is not a final order until the proper legal process is complete.

Do not rely on random online calculators for a final answer. Even a good calculator can be wrong if income, overnights, health insurance, child care costs, or legal rules are entered wrong.

Important: Colorado’s updated law does not mean every parent will pay the same amount, or that older orders automatically change. The judge or agency must use the rules that govern your case. If you estimate support, enter gross pay, the child’s actual overnight schedule, qualifying child care costs, and insurance costs carefully. For the official method, check the court’s calculator page and the current child support worksheet.

If parentage has not been established

Parentage means legally identifying a child’s parents. In Colorado, parentage may be established through a court order, an administrative action by a local child support office, or voluntary acknowledgement. The state parentage page explains these paths.

This matters because a child support order usually cannot move forward against a person until that person is legally recognized as a parent. If you were not married to the other parent, or the other parent is not on the birth certificate, ask your county child support office what parentage step is needed.

If parentage is disputed, the case may take longer. If there are safety concerns, tell the caseworker before notices are sent or meetings are scheduled.

Some parents can sign an Acknowledgment of Parentage at the hospital or through Colorado Vital Records. If parentage is disputed, ask the county office about its legal or genetic-testing process rather than guessing who should sign. The other parent must receive proper legal notice before a support or parentage order is final; if a parent does not respond on time, a default order may be possible.

How payments are received in Colorado

The Family Support Registry is the central payment record system for many Colorado child support and maintenance payments. FSR accounts are set up automatically in many cases, and parents receive an account number by mail.

Colorado’s receiving payments page says payments are processed the same business day they are received, and payments to the person receiving support are generally issued within two business days. Delays can still happen because of banking, employer, case, or address issues.

You may be able to receive support by direct deposit or a child support payment card. If your payment seems missing or wrong, ask FSR for the payment record and ask your county office what happened in the case.

FSR payment help: The registry lists 303-299-9123 (Denver area) and 800-374-6558 (toll free) for account and payment questions. Ask for the payment history, check that your mailing address or bank information is current, and confirm whether the payment was received or sent out. Those are different steps.

If you receive Colorado Works/TANF, ask your caseworker whether child support money is handled differently for your household. The FSR record alone may not explain how public assistance affects the amount paid to you.

When child support payments do not come

If there is a support order and the paying parent does not pay, Colorado Child Support Services can use enforcement tools. The state’s enforcement page says CSS may use income withholding, suspensions and denials, intercepts, credit reporting, and judicial actions when a child support order is not being followed.

Income withholding is one common collection tool. Colorado’s income withholding page says the local county office may verify employment and issue an income withholding order after a support order is established.

Do not assume the office knows every detail. Contact your county office and ask what enforcement step is active, what they need from you, and whether employer, address, or payment information is missing.

If there is still no payment: Ask for an updated balance of unpaid support (also called arrears), the date of the last recorded payment, and whether income withholding or another step has started. An enforcement option may be available, but it does not guarantee money will arrive on a set day. Keep your notices and confirm who is handling the case if the other parent now lives in another state.

How to change a Colorado child support order

A child support order usually stays in place until it is changed by the court or through the proper legal process. A verbal agreement between parents is risky. If the other parent says, “I will pay less for a few months,” get advice before relying on that.

The Colorado Judicial Branch says a child support order may be changed if there is a substantial and continuing change in circumstances. A substantial change generally means the new calculation would make support go up or down by at least 10 percent. A continuing change is more than temporary.

You might ask for a change if a parent’s income or overnight visits change. New child care or health insurance costs may matter too. You may also ask about an order that left out medical or dental support. Colorado Child Support Services also has a changing order page with review and adjustment forms.

If you do not have a child support caseworker and need help with court forms, the Colorado Judicial Branch says you can contact the Self-Help Center at your courthouse. You can also ask about Sherlock self-help centers. Self-help staff can explain forms and procedure, but they cannot be your lawyer.

County review or court motion?

If your case is open with Colorado Child Support Services, the state says a county review request must be in writing. Include the reason for the change, an Income and Expense Affidavit, and records to support the request. The county says a review and change may take up to six months, and the order can go up, go down, or stay the same. Having three years pass since the last review is also one reason you can request a review.

If you use the court instead, follow the current instructions and ask the court which forms apply. Colorado’s court page lists JDF 1403 for a motion to modify and JDF 1404 when parents agree to a change. The court may require service, financial disclosures, fees, and a hearing. Ask about a fee waiver if you cannot afford court costs. The court’s July 2026 instructions also describe deadlines for documents; check those instructions and any orders or notices you receive. Do not assume a county review has the same deadlines as a court filing.

Do not stop paying or accept a new amount based only on a talk or a text. Ask when any change would start and what document confirms it. If the child is close to age 19, ask about ending support; ending it can need a different form and there are exceptions, including some school and disability cases.

If child support creates safety concerns

For some parents, asking for support can trigger threats, stalking, financial control, or abuse. Tell your caseworker if you are worried about harm to you or your children. Colorado says safety information can be updated at any time while your case is open.

If you receive Colorado Works/TANF, you may be required to cooperate with child support unless you have a good reason not to. If cooperation is unsafe, ask the Colorado Works eligibility department about Good Cause. Colorado’s safe access page says Good Cause may let some TANF participants avoid mandatory child support cooperation when pursuing support would create danger.

Do not share a new address, school, work schedule, child care location, or safe phone number with the other parent just to move a case along. Ask the county office about safer communication and nondisclosure options. ASMOM’s domestic violence safety guide can help you plan safer next steps.

Colorado’s child support safety page explains Non-disclosure of Information (NDI) for case records and the separate Address Confidentiality Program (ACP) for some survivors. Ask the county office which steps can keep your address off records shared with the other parent and what might still be visible in court files. Do not assume a protection order or a request to close a CSS case removes every existing court obligation.

If someone may monitor your phone or browser, try to reach an advocate through a safer device when possible. Avoid making sudden device changes that might increase danger. A trained advocate can help you weigh safe contact choices for your own situation.

If your case is delayed, denied, or disputed

A child support application is not the same thing as a court order. If you have waited for an answer, call the county office handling your case. Ask what is holding things up. It may be locating a parent, confirming parentage, serving papers, checking income, or setting a hearing. Ask for the next step in writing when possible.

1. Read every notice. Write down the case number, date, what the office or court decided, and any deadline to respond.
2. Ask what is missing. Request a list of needed papers and ask how to provide them and confirm receipt.
3. Dispute a wrong balance. Ask FSR for its payment record, then compare it with your order and other proof. Ask the county worker how to request a correction.
4. Get help with court papers. Court self-help staff explain forms but do not represent you. Colorado Legal Services or a family lawyer can discuss legal options when deadlines or safety matter.
5. Use backup support meanwhile. Child support is not guaranteed emergency cash; ask about public benefits, food, housing, child care, and local community services.

If you receive a court order, garnishment notice, or appeal-related notice, follow the instructions and deadline on that notice. There is no single appeal deadline for every kind of child support issue.
