Quick answer: District of Columbia child support modification starts with a presumption: a guideline result 15% or more away from your order is presumed a substantial and material change. You can also modify on changed needs or ability to pay, but only from the date the other parent has notice.
This District of Columbia child support modification calculator applies the presumption in D.C. Code 16-916.01(r). Enter your current order and the amount the guideline gives today (you can get it from the District of Columbia child support calculator) and it shows whether the 15% line is met, the monthly difference and what it adds up to after notice. An order less than a year old that departs from the guideline gets no presumption.

What does this modification calculator check?

Frequently asked questions
How much does child support have to change to be modified in the District of Columbia?
A guideline result that varies from the existing order by 15% or more is presumed to be a substantial and material change. A change in the child's needs or the payer's ability to pay can also support a modification regardless of the percentage.
Can the District of Columbia change child support retroactively?
No, except that a modification may run from the date the opposing party was given notice of a pending petition for modification.
Does the 15% presumption always apply in the District of Columbia?
Not within one year of an order that differs from the guideline by court order or merged agreement, and it can be rebutted by special circumstances or by reliance on an older order with a patently unjust result.
Does the District of Columbia review child support orders?
The IV-D agency notifies both parents of the right to a review every 3 years and reviews when support is assigned or when either parent asks, and parents exchange financial information every 3 years.
Does incarceration for contempt justify a District of Columbia modification?
No. Incarceration for contempt for failure to pay child support is not a change in circumstances sufficient to modify support.
