Child support in New Jersey is an obligation that runs from
parent to child rather than from parent to parent. When viewed
through this prism, child-support law in New Jersey becomes
more easily understood.


In most instances, the amount of child support will be determined by New Jersey’s Child Support Guidelines that involve
some complicated formulas based on:
• both parties’ income from all sources (earned and unearned including alimony),
• the amount of overnight parenting time exercised by
each parent,
• the children’s ages,
• health-care and child-care costs, and
• support paid for children from another relationship.

As the New Jersey Child Support Guidelines are formulas, most
disputes involve the methodology or actual data input. For
instance, a party may argue that a spouse earns a substantial
but unreported sum of money from, say, tips, and that would
affect that spouse’s actual income and thus the amount he or she
could be expected to pay for child support.

Parents who are not the residential parent—the one who
doesn’t have the children for most of the time—believe they
have to pay or are paying for all their children’s support. In most
instances, however, that’s not so. Parents who are the primary
residential parents may or may not have a probation account,
an account to which the ex pays alimony and is then sent to
the one who is supposed to receive it, but they pay for all the
children’s expenses not covered by the child- support payments;
they cannot expect the nonresidential parents’ child support to
cover all their children’s expenses. Except in very rare instances,
neither party has the obligation to pay for all of their children’s
support; it’s a shared obligation.


In some cases, the child-support guidelines will not be used or
will deviate from the agreed-upon amount. That’s the case when
an adult child resides away from home during college, or when
the net income of both parties from all sources exceeds $187,200.
In that instance, a deviation from the New Jersey Child Support
Guidelines may be necessary.


When a child-support account is established through Family
Support Services/Probation, there will often be periodic increases in support (cost of living adjustments). Likewise, the
parties may agree to revisit child support at certain set intervals
such as every three years. Child support may also be modified,
however, at any time if there’s a significant change in circumstances. Some common examples of what may be considered a
change in circumstances include these.
• modification of custody or parenting time
• changes (positive or negative) in the incomes of the
• job loss, serious illness, disability
• emancipation of one or more children
• termination of child support in New Jersey

Until recently, New Jersey did not assume the emancipation of
a child or the termination of child support upon a child’s eighteenth birthday. In fact, appellate cases even stated that a child
could even be “unemancipated.” However, recent legislation
presumes emancipation and termination of child support once
a child reaches nineteen. A parent receiving child support for
someone who is nineteen or older can ask the court that the
child support continue if the child is disabled, not out of high
school, going to college, or other compelling reasons. The new
legislation also says that emancipation must occur no later than
when a child reaches age twenty-three.

In New Jersey, children are considered emancipated if they
have moved beyond the “sphere and influence” of their parents,
but it’s rare for the court to say that a college student has moved
beyond that sphere. In New Jersey, both parents are generally
required to contribute to their children’s college costs and at
times up to and including paying toward professional or graduate degrees.
