Many parents feel uncertain about how child support works. Questions often arise about who is responsible for which expenses, how support is calculated, and what happens when unexpected costs come up.
Understanding what child support is intended to cover can help parents reduce confusion and avoid unnecessary conflict.
Base Support
Virginia starts with a base child support amount meant to cover a child’s basic, day-to-day needs. This baseline assumes that both parents share financial responsibility and that support should reflect their combined income. Base support typically covers:
- Housing
- Food
- Clothing
The court uses Virginia’s child support guidelines to determine a total support amount based on the parents’ combined income and number of children. That total is then divided proportionally according to each parent’s share of the income.
For example, if the guideline amount is $1,000 per month and one parent earns 30% of the combined income, that parent would generally be responsible for paying $300 per month in child support.
Add-On Expenses
After the base amount of child support is determined, additional expenses may be added to this amount for other expenses, including:
- Health insurance
- Unreimbursed medical expenses
- Childcare expenses so the parents can work
- Extraordinary medical or dental expenses
- Extracurricular activities
The base amount of child support does not typically include these add-on expenses unless you and the other parent have agreed to this.
Adjustments for the number of overnight visits the child spends with the non-custodial parent can affect the amount of child support.
The court makes decisions regarding children by using the best interests of the child standard. The goal is to maintain the child’s standard of living as it was when the parents lived in one household.
Modifying Child Support
As a child ages or situations change, it may become necessary to adjust the amount of child support. In Virginia, you can request a modification of child support if any of the following apply:
- It has been at least three years since the last modification of the child support order.
- A parent’s income has changed by 25% or more.
- Significant changes in your child’s needs, such as medical or educational, have occurred that justify a modification.
- There have been significant shifts in custody or childcare costs.
To modify your child support order, you will need to file a petition with the court and prove a substantial change has occurred to justify a change in the formal court order. This process is necessary to legally change the order, even if you and the other parent agree.
Documenting Child Expenses
One of the best ways to avoid conflict over child expenses is to keep clear and detailed records of child-related expenses. Track your spending using a spreadsheet, app, or old-fashioned notebook and pen. Keep receipts for these expenses.
Keep a log of the items your ex drops off your child with and make sure you return them when your child returns.

Child support is not a punishment exacted on non-custodial parents. Instead, it is a valuable resource that can help ensure that your child benefits from your contributions. The final amount of support isn’t only for basic necessities; it is a comprehensive consideration of your child’s needs that factors in all significant expenses and the abilities of both parents.
