Child support ensures that both parents contribute financially to their children’s upbringing. Unlike alimony, which is discretionary, child support follows mandatory guidelines in every state. The calculations appear straightforward but disputes over income, expenses, and deviations create substantial litigation.
Guideline Calculations
State guidelines calculate presumptive support based on parental income and custody arrangement. The income shares model used by most states bases support on what parents would have spent on the child in an intact household.
Gross income is the starting point. Wages, salaries, bonuses, commissions, self-employment income, investment income, and other sources are included.
Imputed income applies when a parent is voluntarily underemployed or unemployed. Courts assign income based on earning capacity rather than actual earnings.
Deductions vary by state. Taxes, mandatory retirement contributions, health insurance premiums, and support for other children may reduce income for calculation purposes.
Combined parental income determines the basic support obligation from state tables. The obligation is divided between parents according to income shares.
Adjustments for healthcare, childcare, and extraordinary expenses add to the basic obligation. These costs are typically shared proportionally.
Deviation Factors
Deviations from guideline amounts are permitted for good cause. Courts consider specific factors in deciding whether to deviate.
Shared custody arrangements may reduce support when the obligor has substantial parenting time. More time with the child means more direct expenses.
High income situations may justify deviation when guideline amounts exceed reasonable child-related expenses. Extremely high earners may pay less than strict application would require.
Special needs of the child including medical conditions, educational requirements, and developmental needs may justify higher support.
Other financial circumstances including debt, unusual expenses, and resources of the child may affect appropriate support levels.
Agreement between parents to deviate is not automatically accepted. Courts must find the agreed amount serves the child’s interests.
Income Disputes
Income verification requires documentation. Tax returns, pay stubs, bank statements, and business records establish income.
Self-employment income is frequently disputed. Business deductions that reduce taxable income may not reduce income for support purposes. Lifestyle analysis may reveal income not reflected in tax returns.
Hidden income investigations examine lifestyle, assets, and spending inconsistent with reported income. Forensic accountants trace funds and identify undisclosed sources.
Fluctuating income from commission, seasonal work, or variable business creates averaging questions. Which years to include and how to project future income are contested.
Voluntary income reduction through career changes, reduced hours, or early retirement may not reduce support obligations. Courts examine motivation for income changes.
Establishing Paternity
Paternity establishment is prerequisite to child support for unmarried parents. Without legal paternity, no support obligation exists.
Voluntary acknowledgment is the simplest method. Both parents sign an acknowledgment at birth or later. The acknowledgment establishes legal paternity.
Genetic testing resolves disputed paternity. DNA testing is highly accurate. Court-ordered testing occurs when paternity is contested.
Presumed paternity arises in certain circumstances. Marriage to the mother at birth creates presumption. Living with the child and holding out as father may create presumption.
Disestablishment of paternity is difficult once established. Men who discover they are not biological fathers face challenges overturning paternity findings.
Modification
Modification requires showing changed circumstances. Support orders are not permanent but modification requires justification.
Material change typically means significant income change. A 10 to 20 percent change often meets the threshold. Job loss, disability, and substantial raises may warrant modification.
Change in custody arrangement affects support calculations. More time with one parent changes the allocation of support obligation.
Duration of change matters. Temporary setbacks may not justify modification. Permanent changes warrant adjustment.
Retroactive modification is limited. Support cannot be modified retroactively in most states. Arrearages that accrued before the modification motion remain due.
Automatic review provisions in some orders trigger recalculation at specified intervals. Changed circumstances are assumed, and recalculation occurs.
Enforcement
Wage garnishment is the primary enforcement mechanism. Income withholding orders direct employers to deduct support from wages.
State enforcement agencies pursue delinquent obligors. License suspension, passport denial, credit reporting, and tax refund interception are available tools.
Contempt proceedings hold non-paying obligors in contempt of court. Jail is possible for willful failure to pay.
Interest accrues on unpaid support. Arrearages grow even when current support is paid.
Bankruptcy does not discharge child support. Unlike most debts, support obligations survive bankruptcy in full.
Interstate enforcement through UIFSA provides mechanisms for enforcing orders across state lines. Registration and enforcement in the obligor’s state enables collection.
Termination
Support typically terminates when the child reaches majority. The age varies by state, usually 18 or 19.
Emancipation terminates support earlier. Marriage, military enlistment, and other circumstances may emancipate minors.
College support is required in some states. Courts can order support for educational expenses past majority age.
Disability of the child may extend support indefinitely. Adult disabled children may continue receiving support.
Death of the obligor may terminate or continue support depending on state law and order terms. Life insurance can secure future obligations.
For Service Members
Military child support involves unique income components and enforcement mechanisms.
BAH and BAS are included in income for support calculations. These allowances significantly increase gross income above base pay.
DFAS enforces support orders directly from military pay. Wage garnishment through DFAS is efficient and reliable.
The 10/10/10 rule for DFAS direct payment applies to alimony and property division, not child support. Child support can be garnished regardless of marriage duration.
Maximum garnishment limits apply. No more than 60 or 65 percent of disposable earnings can be garnished for support, depending on circumstances.
Deployment does not suspend support obligations. Support continues during deployment. Arrangements for payment must be made.
PCS moves may trigger modification if income changes significantly with the new duty station. COLA differences and special pays vary by location.
Reserve and Guard activation affects income. Support calculations may need adjustment when income changes with activation.
Command involvement in support enforcement is possible. Failure to support dependents violates regulations. Command can take administrative action.
Paternity establishment for service members follows state law. Military status does not affect how paternity is established.
A military attorney understands how military income is properly included in support calculations, DFAS garnishment procedures, and how military service affects support obligations and enforcement.
