Equitable distribution states: fair, not equal

Updated September 2026. Every rule links to its official source. How we make our numbers.

If your state is not one of the nine community property states, this is your system. It is the more common one, and the more uncertain one, and women are often told "equitable" as if it were a synonym for "equal". It is not. It means a judge, or the two of you, decides what is fair given the facts of this marriage.

The states that use it

Everything except Arizona, California, Idaho, Louisiana, Nevada, New Mexico, Texas, Washington and Wisconsin. In full:

A footnote worth knowing: Alaska, Florida, Kentucky, South Dakota and Tennessee let couples opt in to community property through a special trust, but that only applies if you actually signed one (J.P. Morgan Private Bank). Otherwise those five are equitable distribution states like the rest.

What courts commonly weigh

Every equitable distribution state publishes its own factor list in statute, and the lists rhyme. New York's is a good worked example because it is long, public and typical. Under Domestic Relations Law 236 Part B(5)(d), a court must consider factors including:

• How long the marriage lasted, and the age and health of both people. The statute pairs these in a single factor. A thirty-year marriage between two people in their late fifties is a different case from a six-year marriage between two people in their thirties.
• The income and property each person had at the start of the marriage and at the time the case begins.
• Contributions to acquiring the marital property, including contributions "as a spouse, parent, wage earner and homemaker," and contributions to the other person's career or career potential. This is the clause that puts the years at home on the ledger.
• Loss of inheritance and pension rights, and loss of health insurance benefits, both named as separate factors.
• The probable future financial circumstances of each person, which is where earning capacity does its work.
• Whether property is liquid or not, the tax consequences, and any wasteful dissipation of assets.

Earning capacity deserves a line of its own. Courts look at what each person can realistically earn going forward, not just at last year's W-2. A woman who stepped back from paid work for fifteen years does not have the same earning capacity as her spouse who did not, and that gap is supposed to be visible in the outcome. It is also the reason the income damage after a late divorce is so lopsided: women's household income falls about 41% after a divorce at 50 or older, against 23% for men (US GAO, GAO-12-699).

Your state's factor list will differ from New York's in the details. Look up your own statute, or ask your attorney to read you the list. It is usually one page, and it tells you what arguments actually count.

Why we show a 40% to 60% band

A calculator that prints "your share is 47.5%" in an equitable distribution state is inventing precision. Nobody knows the number until the two of you agree or a judge rules. What is knowable is the marital portion of each asset, and the range that most negotiated outcomes fall into.

So our Marital Share Estimator does the part that is arithmetic and stops at the part that is judgment. It calculates the marital portion of a 401(k), an IRA or a pension, then shows a 40% to 60% band of that portion for equitable distribution states, against a 50/50 starting point for community property states. The band is a planning range, not a prediction and not a promise. Full method on how we make our numbers.

The mechanics are the same either way

Whichever system your state uses, the two calculations underneath do not change:

• Accounts with a balance (401(k), 403(b), IRA) use the subtraction method: today's balance minus the balance on the wedding date, with growth on the premarital piece treated differently from state to state.
• Pensions use the coverture fraction: months married during plan participation divided by total participation months.
• Splitting an employer plan needs a QDRO. A qualified domestic relations order is a separate court order. An IRA divides through the decree instead, with no QDRO (IRS).
• Separate property generally means what you owned before the marriage plus gifts and inheritances received during it and kept separate (IRS Publication 555). That definition is written for community property states, and equitable distribution states use very similar categories.

And the house question is identical everywhere: an even split on paper is often not even after tax. Run the House vs. 401(k) Comparison before you decide to keep it, and the Retirement Runway Calculator to see how long the result actually lasts.

What to do with this

Run the Marital Share Estimator with your wedding date and the balances you can see, and note both ends of the band. Then look up your state's factor list and write down which factors obviously apply to you: length of marriage, years out of paid work, a health issue, a pension you would lose. Those notes are the useful thing to hand a professional. If you are not sure which professional, start here.
