New Jersey divorce law has a few features that catch people off guard. Property division is based on fairness — not a guaranteed 50/50 split. Alimony has four distinct types and a hard rule tied to marriage length. And child support uses net income, not gross, which means the numbers look different from what many people expect. If you're going through a divorce in New Jersey, understanding these basics before you meet with an attorney can help you ask better questions and walk in more prepared.

Property Division: Equitable Distribution, 16 Statutory Factors
New Jersey is an equitable distribution state under N.J.S.A. § 2A:34-23.1. That means courts divide marital property in a way they consider fair — which isn't automatically 50/50. A judge weighs 16 statutory factors and may award 40/60, 55/45, or another ratio based on the specific circumstances of the marriage.
Marital property generally includes all assets and debts acquired by either spouse during the marriage — real estate, bank accounts, retirement savings, vehicles, and investment accounts. The marriage period runs from the wedding date through the date of the complaint for divorce. Separate property — assets owned before the marriage, inheritances, and gifts given to one spouse individually — is generally not subject to division.
One important caution: if separate property gets commingled with marital funds — for example, an inheritance deposited into a joint account — it may lose its separate character. Careful record-keeping matters.
The 16 factors courts weigh include the length of the marriage, each spouse's age, physical, and emotional health, the income and property each spouse brought into the marriage, the standard of living established during the marriage, contributions to the other spouse's education or career, and any written agreements between the parties. No single factor controls — judges apply judgment across all of them.
Suppose a couple has $500,000 in total marital assets — a home with $200,000 in equity, a 401(k) worth $180,000, and $120,000 in joint savings. Starting from a rough midpoint, each spouse might expect around $250,000. But if one spouse contributed significantly more to asset appreciation, or if the other received a substantial inheritance that was kept separate, a judge may award a 55/45 or 60/40 split. Every outcome depends on how the 16 statutory factors apply to the specific facts of the marriage.

Alimony: Four Types, No Formula, and the 20-Year Rule
New Jersey overhauled its alimony law in 2014 — eliminating permanent alimony for most marriages and creating a clearer framework built around four distinct types of support. The statute is N.J.S.A. 2A:34-23. There is no formula for calculating the amount — courts weigh 14 statutory factors and exercise considerable discretion.
The four types of alimony are: open durational alimony (no fixed end date, available only for marriages of 20 years or longer), limited duration alimony (fixed end date, for marriages under 20 years — duration generally may not exceed the length of the marriage), rehabilitative alimony (shorter-term support to help a spouse return to the workforce), and reimbursement alimony (repayment for supporting a spouse through education or career advancement during the marriage).
The 20-year threshold is one of the most significant features of New Jersey's law. For marriages under 20 years, the total duration of alimony generally may not exceed the length of the marriage — with limited exceptions. A 10-year marriage would generally support no more than 10 years of alimony. Marriages of 20 years or more may result in open durational alimony, which continues until a court order changes it — but it terminates when the paying spouse reaches full Social Security retirement age, unless exceptional circumstances apply.
Suppose Spouse A earns $110,000 per year and Spouse B earns $32,000 per year after a 12-year marriage. Spouse B scaled back a career to manage the household and raise children. A court weighing the income gap, the marriage length, Spouse B's earning capacity, and the standard of living during the marriage might consider limited duration alimony in the range of $1,800–$2,800 per month for up to 12 years. This is illustrative only — actual awards depend on how the judge weighs all 14 factors in the specific case.
| Alimony Type | When It Applies | Duration |
|---|---|---|
| Open durational | Marriages of 20+ years | No fixed end — terminates at paying spouse's full retirement age |
| Limited duration | Marriages under 20 years | Generally may not exceed length of the marriage |
| Rehabilitative | When a spouse needs time to re-enter the workforce | Shorter term; tied to a specific plan or timeline |
| Reimbursement | When one spouse funded the other's education or career advancement | Fixed — tied to the amount contributed |

Child Support: Income Shares Using Net Income
New Jersey calculates child support using the Income Shares Model under Court Rule 5:6A. The model combines both parents' incomes and looks up the basic child support obligation on a state schedule — then each parent pays their proportional share based on their percentage of combined income.
One key New Jersey distinction: the calculation uses net income — income after federal and state taxes, FICA, mandatory retirement contributions, union dues, and existing support orders — rather than gross income. This makes the starting numbers lower than in states that use gross income, but the results are calibrated to each family's actual take-home situation.
The state uses two separate worksheets. The sole parenting worksheet applies when one parent has the child 263 or more nights per year (more than 72% of overnights). The shared parenting worksheet applies when the parent of alternate residence has 104 or more overnights per year — roughly every other weekend plus additional time. The shared parenting calculation adjusts each parent's obligation based on their parenting time percentage.
The basic obligation from the schedule covers the child's core needs. Courts then add adjustments for health insurance premiums, unreimbursed medical costs, and work-related childcare expenses — split between parents in proportion to their income shares.
Suppose Parent A has a net monthly income of $4,500 and Parent B has a net monthly income of $2,500. Combined net monthly income is $7,000. Looking up one child on the NJ schedule at that income level, the basic obligation might be approximately $1,050 per month. Parent A's share would be roughly 64% ($672/month) and Parent B's share roughly 36% ($378/month). Health insurance and childcare costs are added on top and split proportionally. These figures are illustrative — the actual schedule and each family's specific deductions determine the real numbers.

Retirement Accounts: QDROs and the Coverture Fraction
Retirement accounts accumulated during the marriage are marital property in New Jersey and subject to equitable distribution. The portion earned before the marriage is generally separate. Courts use the coverture fraction — months of the marriage overlapping with the retirement plan divided by total months in the plan — to identify the marital share.
Dividing a 401(k), 403(b), or pension typically requires a Qualified Domestic Relations Order (QDRO) — a court order directing the plan administrator to split the account. A QDRO allows the transfer to happen penalty-free and without triggering taxes at the time of the transfer. Without one, early withdrawal penalties and income taxes may apply.
New Jersey state and municipal pensions — including PERS, TPAF, and PFRS — have their own division rules and require state-specific procedures. These pensions are not divided by QDRO; instead, the plan has its own domestic relations order process.
