Frequently Asked Questions
Child Support in New Jersey
Discover what you need to know about Child Support Laws in New Jersey.
New Jersey calculates child support under the New Jersey Child Support Guidelines (Appendix IX of the Court Rules).
New Jersey follows an income shares model, meaning the court estimates what parents would have spent on the child if living together and divides that amount proportionally based on each parent’s income.
The calculation generally considers:
Both parents’ gross incomes
The number of children
A statewide child support schedule
Health insurance premiums for the child
Work-related childcare expenses
Parenting time (overnights)
Other court-approved adjustments or deviations
New Jersey uses standardized worksheets to determine the presumptive support amount.
For an estimate tailored to your situation, you can use the Deliberately.ai child support calculator above—but only a court order is legally binding.
Child support in New Jersey is commonly influenced by:
Each parent’s income
The number of children
Parenting time and overnights
Health insurance costs for the child
Work-related childcare expenses
Other dependent support obligations
Court-approved deviations when strict guideline application would be inappropriate
Cases involving self-employment, fluctuating income, or complex custody schedules may require detailed financial documentation.
There is no universal amount.
The final figure depends on:
Both parents’ financial information
The New Jersey guideline schedule
Parenting time adjustments
Health insurance and childcare allocations
Any approved deviations

In New Jersey, child support does not automatically end at age 18.
Under current law, support generally ends when the child:
Turns 19, unless extended by court order
Support may continue beyond age 19 if:
The child is still in high school
The child is attending college or post-secondary education
The child has a disability
Other circumstances justify continuation
Always review your specific court order.
Not necessarily.
Wage withholding may continue unless formally terminated.
Any arrears remain owed even after the current obligation ends.
Extension beyond 19 requires appropriate application and court approval.
Always confirm termination or extension procedures through the court.
Yes.
A child support order may be modified when there is a substantial change in circumstances, such as:
Significant income changes
Job loss or promotion
Changes in parenting time
Changes in the child’s needs
Modifications generally apply prospectively (from the filing date), not retroactively to already-owed support.
Timeframes depend on:
Whether the case is contested
Court scheduling
Whether income documentation is disputed
Uncontested matters may resolve more quickly than contested cases.
New Jersey child support is intended to cover:
Housing
Food
Clothing
Transportation
Basic living expenses
Some routine child-related costs
Certain expenses, such as unreimbursed medical costs or extracurricular activities, may be allocated separately in the court order.
It can—but only if:
The cost is included in the guideline calculation, and
The court order reflects the adjustment.
Paying expenses outside the court order does not automatically reduce your obligation.
New Jersey generally considers gross income, which may include:
Wages and salary
Bonuses and commissions
Overtime (when consistent)
Self-employment income
Investment or rental income
Other recurring income
If a parent is voluntarily unemployed or underemployed, the court may impute income based on earning capacity.
Nonpayment may result in enforcement actions such as:
Wage garnishment
Tax refund intercept
Liens
License suspension
Contempt proceedings
Arrears continue to accumulate until paid in full.
Nonpayment may result in enforcement actions such as:
Wage garnishment
Tax refund intercept
Liens
License suspension
Passport denial
Contempt proceedings
Arrears continue to accumulate until paid in full.
Arrears generally:
Remain owed until paid
May be collected through enforcement tools
Do not disappear when the child reaches the age of termination
Yes.
Income withholding is common, and courts or New Jersey Probation Child Support Enforcement may use additional collection tools when necessary.
Not automatically.
New Jersey guidelines include parenting time adjustments based on the number of overnights. Even in shared custody arrangements, support may still be owed depending on income differences.
In certain cases involving disability or special needs, support may continue beyond age 18 (or 19 if still in high school), depending on court findings.
These cases can be legally complex and may require legal guidance.
Child support cases are handled through New Jersey Superior Court (Family Division) and enforced through Probation Child Support Enforcement.
If income or parenting time issues are likely to be contested, consulting a New Jersey family law attorney before filing can help avoid delays and mistakes.
A lawyer is not required for straightforward cases, but it is strongly recommended when:
Income is disputed
Self-employment is involved
Arrears exist
A deviation is requested
Custody or parenting time is contested
You will typically need:
Recent pay stubs
Federal and state tax returns
Proof of health insurance costs
Childcare documentation
Existing court orders
Incomplete financial documentation can delay proceedings.

How Long Does a Child Support Modification Take in Louisiana?
Michigan calculates child support using the Michigan Child Support Formula (MCSF), which Michigan courts are required to use when setting or changing child support.
Michigan’s approach is based on an income-shares model, meaning the formula estimates what parents would have contributed toward the child if they lived together, then allocates responsibility between parents.
The calculation is based on:
Both parents’ incomes (used to determine each parent’s support share)
Number of children
A statewide support schedule/formula inputs (per MCSF)
Parenting time / overnights (Michigan applies a parental time offset when overnights can be determined)
Medical support (health insurance and ordinary medical considerations)
Work-related childcare expenses
Other adjustments and court-approved deviations under the MCSF
