• Duration framework: For marriages under 20 years, limited duration alimony generally may not exceed the length of the marriage except for good cause; longer marriages may support open durational alimony.

What alimony is (and is not)

Alimony is court-ordered support from one spouse to the other after separation or divorce. It is separate from child support (see N.J. Court Rules Appendix IX; N.J.S.A. 2A:34-23) and from property division. A single judgment may include all three, but each has its own legal tests.

No spouse is automatically entitled to alimony. Courts typically ask whether one party has a genuine need and whether the other has the ability to pay, then apply New Jersey's statutory framework.

Eligibility and statutory factors

No numeric formula. Courts apply statutory factors (need, ability to pay, duration of marriage, parental responsibilities, and more).

Fault. Fault may be considered among the statutory factors but is rarely dispositive alone.

Document income, earning capacity, health, length of marriage, contributions as homemaker or to the other spouse's career, and the marital standard of living. Those facts drive both temporary (pendente lite) and final awards.

Types of alimony in New Jersey

Open durational, limited duration, rehabilitative, and reimbursement alimony.

Labeling matters. Rehabilitative awards usually require a plan (schooling, retraining, re-entry to the workforce). Durational or term awards run for a fixed period. Lump-sum or reimbursement awards may be non-modifiable depending on the judgment language and statute.

How amount is set

New Jersey does not use a statewide calculator for final alimony. Judges weigh the statutory factors and the record. Online “alimony calculators” are at best rough illustrations and are not controlling.

Temporary support while a divorce is pending often follows different local practices or guidelines than the final award. Confirm what your county or division actually uses.

How long alimony lasts

For marriages under 20 years, limited duration alimony generally may not exceed the length of the marriage except for good cause; longer marriages may support open durational alimony.

Permanent / indefinite support. Open durational alimony (the modern successor to permanent alimony) is available especially after long marriages, subject to modification and termination statutes.

When alimony ends or can be changed

Death, remarriage, or cohabitation under statutory standards; reaching full retirement age can support modification/termination of open durational awards.

Either party may usually seek modification upon a substantial change in circumstances unless the award was expressly made non-modifiable. Retirement, disability, remarriage, cohabitation, and large income swings are frequent triggers — but the statutory test and burden of proof are New Jersey-specific.

Taxes

TCJA eliminated federal deductibility for post-2018 decrees; New Jersey tax treatment should be confirmed because state conformity has been an evolving issue.

Child support remains non-deductible and non-taxable. Do not assume alimony treatment mirrors child support.
