D.C. child support is based on the number of overnight visits

Washington, D.C. uses overnights, or where the children sleep for figuring shared custody timeshare percentages in its child support formula. These totals then convert to a percentage.

Besides income, parenting time percentages are a key part of the Washington, D.C. child support formula. Your parenting time directly affects your child support, whether you pay or receive. Use the calculator above to get an estimate of your support amount.

Most overnight totals are estimates (and thus incorrect)

Washington, D.C. lawyers and judges often rely on overnight estimates only, even if they are incorrect, because counting total hours is tedious and time consuming. Divorcing parents usually rely on these estimates as well.

Using estimates means your overnight totals can be wrong when compared to your actual parenting time schedule. This means your child support amount will not be fair or exact.

How to calculate overnights instead of relying on estimates

To calculate overnights, the easiest and most accurate way is to use software. Without software, you're forced to count each night for a whole year, which is error-prone when you include alternating holidays, summer break, and any changes to the schedule throughout the year.

Using software, you can also tweak your schedule to see how even little changes affect your total overnights, and you can see how your overnights change each year due to holidays and other events.

You can also track what actually happens, and show how many overnights you've actually received for any period of time. Historical information is a powerful tool when you request a child support modification or when you request more parenting time.

Fast facts on Washington, D.C. child support

In any divorce, Washington family courts award custody of the children to one or both parents. Custody is divided into legal custody and physical custody. Child support amounts are tied to physical custody designations.

Washington, D.C. sole physical custody: The children reside with and are supervised by the residential parent, while the other parent is entitled to overnight visitations. In Washington, D.C., when the nonresidential parent has fewer than 128 overnights, or less than 35% of the total time with the children, the family court considers it a sole custody case.

Washington, D.C. joint physical custody: Each parent has significant periods of physical custody, which allows them frequent and continuing contact with their children. Washington, D.C. requires that each parent host at least 128 overnights, or 35% of the time per year, to qualify for joint physical custody.

Washington, D.C. child support formula and parenting time adjustment

Washington, D.C. family courts use formulas that consider both parents' incomes and the needs of the child to arrive at a monthly child support amount.  A parenting time adjustment is given based on joint custody.

Sole custody formula: The total income from the nonresidential parent is put into the formula. Certain deductions reduce that total to an adjusted income. To be considered a sole custody case, the nonresidential parent spends fewer than 128 days per year, or less than 35 percent of the time, with the children. There is no parenting time credit given for sole custody situations. The residential parent receives child support from the nonresidential parents according to Washington, D.C. law.

Joint custody formula: A different formula is used for joint custody child support calculations. Both household incomes figure into the formula, unlike the one for sole custody. In the District of Columbia, when the family court orders joint physical custody, the nonresidential parent must host the children for 128 days per year or more. The more overnights, the greater the credit toward child support.

Examples of sole child custody and Washington, D.C. child support

Consider the hypothetical case of Robert and Mary. Robert's adjusted income is $4,000 per month, while Mary's adjusted monthly income is $2,400. They have two children.

See how the child support amounts change in these examples:

  • Scenario #1: Robert is the nonresidential parent in this sole custody case, and is scheduled to host the children for fewer than 128 days per year. He pays $921 in child support each month to Mary.
  • Scenario #2: Mary is the nonresidential parent and hosts the children for fewer than 128 days per year. She pays $552 in child support to Robert.

In Washington, D.C. sole custody cases, the nonresidential parent pays child support to the residential parent, regardless of income.

Examples of shared custody formula and Washington, D.C. child support

Consider the hypothetical case of Robert and Mary. Robert's adjusted monthly income is $4,000, while Mary's adjusted monthly income is $2,400. They have two children.

See how the child support amounts change in these examples:

  • Scenario #1: Robert hosts the children for 130 days, which is just over the minimum to qualify for joint physical custody. He pays $594 in child support per month to Mary.
  • Scenario #2: Robert hosts the children for 150 days. He pays $473 in child support per month to Mary.
  • Scenario #3: Robert hosts the children for 175 days. He pays $321 in child support per month to Mary.
  • Scenario #4: Robert and Mary agree to a 50/50 split, or 182 days. He pays $279 in child support per month to Mary. This is because he is the higher earner.

In Washington, D.C. joint custody, the nonresidential parent pays child support to the residential parent.

In the case of a 50/50 split, the higher earner generally pays child support to the lower earner to ensure the children's standard of living is the same in both locations.

Other factors in the Washington, D.C. child support formula

The District of Columbia's child support formula uses the following information to calculate your monthly amounts for joint custody child support:

Eligible children: In Washington, D.C., child support payments continue for each child until he or she turns 21, at any point where the child becomes self-supporting, such as through marriage or military service.

Gross earnings: Gross earnings are established based on tax records and current pay stubs. Washington, D.C. law uses one parent's income from the equivalent of one full-time job to determine a child support amount in sole custody cases. Both incomes figure into joint custody child support.

Specific deductions: There are some deductions allowed by Washington, D.C. family courts that allow an adjustment of the income, including health insurance premiums for the children, support for other children and child care expenses, for example.

How accurate child support helps your children

Paying accurate child support helps your children in several ways, primarily because it ensures their financial needs are met.

Here are some other reasons why accurate overnight numbers help you, the other parent and your children:

  • It provides a fair way to determine your child support amounts
  • It guarantees the child support amount reflects each parent's responsibilities
  • It allows for modifications if your actual time and scheduled time are different
  • It is compliant with the laws of the District of Columbia

Your financial obligations to your children don't end with divorce, so whether you are paying or receiving child support, you owe it to your children to pay or receive the proper amount.
