Alimony in New Jersey: Who Qualifies and How Long It Lasts

In New Jersey, how long alimony lasts depends heavily on how long the marriage or civil union lasted. For a marriage or civil union under 20 years, the total length of alimony generally cannot exceed the length of the marriage itself, except in exceptional circumstances. Open-ended alimony with no preset end date — now called "open durational" alimony — is only available after a marriage or civil union of 20 years or longer, and even then only absent exceptional circumstances. There is no fixed dollar formula; a New Jersey judge weighs a list of statutory factors and can award one of four different types of alimony depending on the situation.

The four types of alimony New Jersey recognizes

New Jersey law recognizes four distinct types of alimony. Which one applies depends on the facts of the marriage and the goal the payment is meant to serve:

• Open durational alimony — alimony with no set end date, available only after a marriage or civil union of 20 years or more, absent exceptional circumstances.
• Rehabilitative alimony — shorter-term support meant to help a spouse become self-supporting again, such as while finishing school or re-entering the workforce.
• Limited duration alimony — support for a set period of time, typically used for shorter marriages where open-ended support isn't appropriate.
• Reimbursement alimony — support meant to repay a spouse for contributions made toward the other spouse's education, training, or career advancement during the marriage.

Open durational alimony replaced what used to be called "permanent alimony" under a 2014 overhaul of New Jersey's alimony law. If you see older cases, articles, or agreements referring to "permanent alimony," that terminology no longer reflects current New Jersey law — it was formally eliminated by that 2014 reform.

How long alimony can last

The core durational rule is straightforward for shorter marriages: for any marriage or civil union that lasted less than 20 years, the total length of alimony is not supposed to exceed the length of the marriage or civil union itself — except in exceptional circumstances a court identifies and explains. In practice, this means a 10-year marriage generally cannot produce more than roughly 10 years of alimony absent something unusual in the case.

For marriages or civil unions of 20 years or longer, a court has the option of awarding open durational alimony, which has no built-in end date. That does not mean it is unconditional or permanent in every sense — open durational alimony can still be modified or terminated later based on changed circumstances, including retirement, job loss, or the recipient's cohabitation, discussed below.

The factors a New Jersey judge has to weigh

New Jersey law requires courts to consider and make findings on 14 separate statutory factors when deciding whether to award alimony, what type, and in what amount. The law is explicit that no single factor automatically outweighs the others — if a court wants to give one factor extra weight, it has to make specific written findings explaining why. Because the exact list and weighting are fact-specific and technical, this is an area where reviewing the current statutory language or talking with a New Jersey family law professional is worthwhile rather than relying on a summary.

When alimony can change or end

These rules involve age, employment, and relationship status thresholds that can shift over time — treat them as time-sensitive and confirm current status with your court or a New Jersey family law professional before relying on them.

Retirement

New Jersey law creates a rebuttable presumption that alimony terminates once the paying spouse reaches full retirement age. "Full retirement age" here is tied to the age for full Social Security retirement benefits under federal law. Because it's a rebuttable presumption rather than an automatic cutoff, either side can ask a court to depart from it based on the specific facts of the case.

Job loss or reduced income

If the paying spouse is not self-employed and loses their job or otherwise has a significant drop in income, New Jersey law generally requires that person to wait until they have been unemployed for 90 days before applying to court to modify alimony. If the modification is eventually granted, relief can be made retroactive back to the date the income loss actually occurred — so the 90-day wait affects when you can file, not necessarily how far back relief can reach.

Cohabitation

Alimony can be suspended or terminated if the person receiving it is cohabiting with another person in a relationship that resembles marriage, even if the couple hasn't remarried or entered a civil union. What counts as "cohabitation" in this sense is a fact-specific question, so if this situation applies to your case, it's worth getting a current, case-specific read rather than assuming any one detail (like a shared address) is automatically decisive.

Taxes on alimony in New Jersey

Federal tax treatment of alimony changed for divorces finalized after 2018 under federal tax reform, but New Jersey's own state income tax rules did not follow that federal change. For New Jersey state income tax purposes, alimony remains deductible by the person paying it and taxable as income to the person receiving it. That means your federal and New Jersey state tax treatment of the same alimony payments may not match — something to flag for whoever prepares your taxes, and worth double-checking against current guidance since federal and state tax rules can diverge further over time.

Alimony and bankruptcy

If either spouse files for bankruptcy, federal bankruptcy law treats alimony and child support as a "domestic support obligation." That means alimony generally cannot be wiped out in bankruptcy, and it is paid ahead of most other unsecured debts in a bankruptcy case. Debts from a property settlement in a divorce decree (as opposed to alimony or child support itself) are also generally treated as non-dischargeable in a typical Chapter 7 bankruptcy case. In short: filing for bankruptcy is not a reliable way to escape a New Jersey alimony obligation.

What you can do in New Jersey

1. Identify which type of alimony might apply. Look at the length of your marriage or civil union first — it's the biggest factor separating open durational alimony (20+ years) from limited duration, rehabilitative, or reimbursement alimony.
2. Gather financial documentation. Because courts weigh multiple statutory factors, having clear records of income, expenses, and contributions made during the marriage will matter regardless of which type of alimony is at issue.
3. Note any time-sensitive triggers. If you or your former spouse has lost a job, is nearing full retirement age, or has started cohabiting with a new partner, understand that these can be grounds to modify or end alimony — but the 90-day waiting period for job-loss modifications applies specifically to non-self-employed obligors, so confirm how it applies to your situation.
4. Check both federal and New Jersey tax treatment. Don't assume your alimony is treated the same way on your federal return as on your New Jersey state return — confirm with a tax preparer familiar with current New Jersey rules.
5. Talk to a New Jersey family law professional before filing anything. The 14-factor test, the "exceptional circumstances" exception to the durational cap, and what counts as cohabitation are all fact-intensive determinations that a summary like this one cannot resolve for your specific case.
