Quick Reference
Starting point: Virginia calculates child support under Code Section 20-108.2, using gross income, number of children, and custody arrangement.
Shared custody threshold: When both parents have 90 or more parenting days per year, the shared custody formula applies.
Guideline formula: Combined gross income → statutory table amount → divided proportionally between parents.
Mediation advantage: Parents may adopt the guideline, agree to a different amount, share child-related expenses directly, or use a hybrid of both. Then, the attorney-mediators at Kales & Kales draft a legally binding, court-enforceable agreement for you.
Child Support Prerequisites in Virginia
Before calculating support, the following must be established:
- Legal parent-child relationship confirmed
- Virginia has jurisdiction
- Gross income information available for both parents
- Health insurance and work related childcare costs for the child(ren)
- Custody or parenting schedule established
With these elements in place, the statutory framework may be applied — but mediation allows for thoughtful flexibility beyond the default formula.

How Child Support Is Calculated in Virginia
Virginia child support is governed by Virginia Code Section 20-108.2. The calculation follows a three-step process.
Determine Each Parent’s Gross Monthly Income
Gross income includes salary, wages, bonuses, commissions, self-employment income, rental income, dividends, severance pay, and certain retirement or disability benefits. Virginia courts may also impute income to a parent who is voluntarily unemployed or underemployed below their earning capacity.
Combine Incomes and Apply the Statutory Table
The combined gross income is matched to a statutory schedule based on the number of children, producing a total child support obligation. Each parent is then responsible for their proportional share of that total. Health insurance premiums and work-related childcare costs paid by either parent are added to the base obligation before the proportional split.
Adjust for Custody Arrangement
Virginia distinguishes between two formulas based on parenting time:
Sole / Primary Custody: If the non-custodial parent has fewer than 90 days per year, the standard formula applies.
Shared Custody: When each parent exercises 90 or more parenting days per year, Virginia uses the shared custody formula under Code Section 20-108.2. A day is when a child is with a parent for a continuous 24-hour period. A half-day day is when a child is with a parent overnight, but for less than 24 hours.
Mediation allows parents to discuss custody and support together, creating arrangements that reflect their practical realities rather than treating them as separate calculations.
Calculation Overview
Deviation from the Virginia Child Support Guidelines
While the guideline amount is presumed correct, courts may deviate when applying it would be unjust or inappropriate. Factors that can support deviation include:
- A child’s special medical or educational needs
- Imputed income for a voluntarily underemployed parent
- Significant travel expenses related to visitation
- Support obligations for other children from a prior relationship
- Relative assets and earning capacities of each parent
In mediation, parents can evaluate these factors collaboratively and agree to amounts above or below the guideline or even ignore the guideline altogether.
Four Mediation Approaches to Child Support
Unlike litigation, mediation gives families flexibility to craft child support arrangements tailored to their circumstances. At Kales & Kales, parents typically explore one of four approaches:
Adopt the Guideline Amount
Choose the statutory calculation for predictability. This mirrors what a court would likely order and simplifies future modification discussions.
Negotiate a Different Monthly Amount
Parents may agree to a monthly amount above or below the guideline based on income fluctuations, property division, or other financial factors specific to their situation.
Share Child-Related Expenses Directly
Instead of a fixed monthly payment, parents share actual child-related costs — extracurriculars, school fees, clothing, unreimbursed medical expenses — as they arise. This keeps payments tied directly to children’s needs.
Hybrid: Base Payment + Shared Expenses
Many families use a base monthly payment combined with proportional sharing of specific child-related costs. This structure provides stability while addressing real-world expenses.
Modifying Child Support in Virginia
Either parent may petition the court for a modification when there has been a material change in circumstances since the last order. Qualifying changes typically include:
- A significant shift in either parent’s income
- A change in the custody or parenting schedule
- A change in the child’s health insurance or childcare costs
Minor or temporary income fluctuations alone do not generally meet the material change standard. Parents who reach an updated agreement through mediation must still submit a consent order to the court.
Mediation is an efficient venue to revisit and update agreements collaboratively, without returning to adversarial proceedings.
Enforcement: What Happens if Support Goes Unpaid
Nonpayment of court-ordered child support can trigger several enforcement actions under Virginia law:
- Wage withholding directly from the paying parent’s employer
- Federal and state tax refund interception
- Driver’s license suspension
- Suspension of professional or recreational licenses after 90 days of nonpayment, or when the arrearage exceeds $5,000
- Contempt proceedings, which can result in incarceration
Unpaid support also accrues interest. Addressing disagreements early through mediation often avoids escalation and preserves the co-parenting relationship.
When Mediation May Not Be Appropriate
Some situations may require litigation, including:
- Domestic violence or coercive control
- Hidden assets or income concealment
- Severe power imbalance between the parties
- Refusal to disclose financial information
