Text sizeJump to: (a) (b) (c) (d) (e)

(a) All orders and judgments that include child support entered, modified, or enforced on or after September 1, 1998 shall provide that the child support amount will be adjusted every two years to reflect the cost of living.
(b) Orders and judgments that include child support entered, modified, or enforced on or before August 31, 1998 shall be prospectively subject to adjustment every two years to reflect the cost of living.
(c) The cost-of-living adjustment shall be based on the average change in the Consumer Price Index for the metropolitan statistical areas that encompass New Jersey and shall be compounded.
(d) Before a cost-of-living adjustment is applied, the parties shall be provided with notice of the proposed adjustment and an opportunity to contest the adjustment within 30 days of the mailing of the notice. An obligor may contest the adjustment if the obligor's income has not increased at a rate at least equal to the rate of inflation as measured by the Consumer Price Index or if the order or judgment provides for an alternative periodic cost-of-living adjustment. A cost-of-living adjustment shall not impair the right of either parent to apply (1) to the court for a modification of support provisions of the order or judgment based on changed circumstances, or (2) to the State IV-D agency or its designee for a three-year review of a Title IV-D child support order, without the need to show changed circumstances.
(e) The forms and procedures to implement cost-of-living adjustments shall be prescribed by the Administrative Director of the Courts.

Plain-English Summary

Support that never moves loses value quietly. This rule builds the correction in: orders and judgments that include child support are adjusted every two years to reflect the cost of living. Orders entered on or after September 1, 1998 must say so; older orders are prospectively subject to adjustment anyway.

The measure is specified. The adjustment is based on the average change in the Consumer Price Index for the metropolitan statistical areas that encompass New Jersey, and it is compounded rather than applied to the original figure each time.

Nothing happens without warning. The parties get notice of the proposed adjustment and 30 days from the mailing to contest it. An obligor can object on the ground that their income has not risen at least as fast as inflation, or that the order already provides its own periodic adjustment. And the adjustment does not use up anyone's other rights — either parent may still seek modification for changed circumstances, or ask the State agency for a three-year review of a Title IV-D order without showing changed circumstances at all.

Frequently Asked Questions

How often is New Jersey child support adjusted for inflation?

Every two years, to reflect the cost of living.

How is the adjustment calculated?

On the average change in the Consumer Price Index for the metropolitan statistical areas that encompass New Jersey, compounded.

Can I object to a cost-of-living increase?

Yes. You get notice and 30 days from its mailing to contest. An obligor may contest if their income has not increased at a rate at least equal to inflation as measured by the Consumer Price Index, or if the order provides an alternative periodic adjustment.

Does a COLA stop me from seeking a modification?

No. A cost-of-living adjustment does not impair either parent's right to apply to the court for modification based on changed circumstances, or to apply to the State IV-D agency for a three-year review of a Title IV-D order without showing changed circumstances.
