Child Support & Maintenance File Editor

Follow the guidelines in C.R.S. § 14-10-115 (for Child Support) and C.R.S. § 14-10-114 (for Maintenance) to determine the values you should enter for each field.

There is no Save button on the file editor page. Every time you change a value and step off the field, the change is automatically saved.

All amounts should be entered as Monthly Amounts.

Press the Print Worksheet button to generate the printed forms which can be filed with the court.

To change the file settings that were entered when creating the file, open the menu at the right end of the file header and select Edit File Settings.

If the file uses an older version of the law, a notice is shown in the file header. Press the Change link to move the file to a different law version.

For Scratch Pad calculations, the menu provides a Save As File option, to save the temporary calculation as a regular file.

As you enter data, the calculation results are updated automatically. Press the details button next to a result to see a preview of the calculation details.

Some fields provide a Set as Default button when their value differs from your current default. Press it to save the value as your personal default for new files.

Multiple Calculations

With an active subscription, a file can hold up to three calculations, shown side by side. Use this option to compare alternative scenarios for the same case.

Press the Add Calculation button and select whether to copy an existing calculation or add a blank one.

To rename or delete a calculation, use the buttons next to the calculation name.

The Print Worksheet page can print a worksheet for each calculation, or a side by side comparison of all of them.

Section Comments

Every section of the editor provides a Show Comments button, which opens a comment box for the section. These comments are not printed on any form and are not searchable. They are only for internal tracking.

Child Support Section

Enter the number of children for this calculation. Leave empty if you want to calculate maintenance without calculating child support.

Set the number of children to a value between zero and six. Setting this value to zero will skip child support calculation. The guidelines do not provide information beyond six children.

Do not include non-joint children in this field. You can enter the number of non-joint children in the Income section.

Select the Same Schedule option if all children share the same overnights schedule. Otherwise, select the Different Schedules option and enter the overnights per child. See C.R.S. § 14-10-115 (8)(g).

Enter the number of overnights for one of the parties. The number of overnights of the other parties is calculated automatically.

Press the calculator icon next to an overnights field for the following options:

• Assign all overnights to the selected party.
• Split the overnights evenly between the parties.
• Estimate the number of overnights for the selected party using the overnights calculator.

The Child Support Guidelines do not provide information on combined monthly income above $40,000 ($30,000 for law versions before 2026). Use the Extrapolate switch to determine whether Math4Law should extrapolate the result beyond that amount, or cap it at that level.

Maintenance Section

You can calculate the maintenance in this case, or enter the value manually.

Enter the marriage length in years and months to calculate the maintenance term. The calculated term is displayed below the marriage length. The guidelines do not provide a term for marriages shorter than 3 years or longer than 20 years, and the editor notes when the marriage length is outside this range.

CRS § 14-10-114(3.5) states that for annual income above $240,000 ($20,000 monthly income), the standard calculation method does not apply. Use the Extrapolate switch to determine whether Math4Law should use the standard calculation method above $20,000, or cap the income at that level.
