Quick Answer: If you have 50/50 custody in Colorado, the parent who earns more typically pays child support. Child support payments are based on both parents’ incomes, the number of overnights each parent has, and certain child-related expenses, not just parenting time.


Many parents assume that equal custody means no one pays child support, yet Colorado child support calculations are income-driven. Even with 50/50 custody, one parent may still owe support.

Here’s how it works.

How Courts Calculate Child Support With 50/50 Custody

Even when custody is split equally, courts apply a statutory child support formula. In Denver County, Adams County, and other Colorado district courts, judges generally follow these guidelines unless there is a legally supported reason to deviate.

The calculation considers:

  • Each parent’s gross monthly income
  • The number of annual overnights
  • Health insurance premiums
  • Work-related childcare costs
  • Extraordinary medical or educational expenses

Once those figures are entered into the worksheet, the formula determines whether a child support payment is owed, and by whom.

Because income plays a significant role in the calculation, the higher-earning parent often pays the difference necessary to balance financial resources between households.

Why Do I Pay Child Support With 50/50 Custody?

Equal visitation or parenting time does not mean equal income. If one parent earns significantly more, the formula may result in that parent paying support, even if parenting time is shared 50/50.

You may still owe child support if:

  • Your income is higher than the other parent’s
  • The guideline worksheet shows a financial imbalance
  • Certain child-related expenses are allocated differently

The purpose of child support is to promote the child's financial stability in both homes, rather than to reward or penalize either parent.

What Counts as child support payments?

Child support is more than just a monthly transfer of money. A child support order may require a parent to:

  • Maintain health insurance coverage
  • Share uninsured medical expenses
  • Contribute to childcare costs
  • Cover educational expenses
  • Share travel expenses related to parenting time

Even with 50/50 custody, these financial responsibilities must be fairly divided. Read our blog post "What Does Child Support Cover in Colorado?" to learn more. 

Can Parents Agree to Different Child Support Arrangements With 50/50 Custody?

In some cases, courts may approve an agreement between parents; however, those agreements must comply with Colorado’s child support guidelines and must be in the child’s best interests.

Judges will generally reject arrangements that:

  • Allow one parent to pay substantially less than the guideline calculation
  • Attempt to exchange parenting time for reduced financial support
  • Shift financial responsibility in a way that disadvantages the child

Because child support directly impacts a child’s well-being, courts are cautious about approving deviations from the formula. If one parent is experiencing financial difficulties, it is possible to request a modification in child support payments.

Speak With a Denver Child Custody and Child Support Attorney

Although Colorado uses a statewide child support formula, the details matter. Accurate income documentation, proper expense reporting, and correct parenting time calculations can significantly affect the final child support payment amount. Even small adjustments in income or overnights can change the outcome.

If you are asking, “If you have 50/50 custody, who pays child support?” the answer depends on the specific financial facts of your case.
