Modeled estimate, not a state calculation. This figure is ours rather than New Hampshire's. The arithmetic behind it is a national approximation that runs the same way in every state: 30 percent of the difference between the two incomes, scaled by a factor for the length of the marriage. No New Hampshire document was opened to produce it and no New Hampshire rule is applied inside it. Read it as a planning band rather than a figure a court has committed to, because a New Hampshire judge applying New Hampshire's own law can land somewhere else.

Our record classifies New Hampshire as one of the small group of states that write a spousal support formula into the statute itself. This estimate is not that formula and does not implement it. Nobody here has read New Hampshire's statute, and we would rather tell you that than run arithmetic of our own and put New Hampshire's name on the result. Where the two differ, the statute is right and we are not. A family law attorney licensed in New Hampshire can run the statutory calculation on your own figures, and that is the number to plan around.

Alimony Calculator in New Hampshire: What You Should Know

Our copy states term alimony in New Hampshire at 23 percent of the difference between the parties' adjusted gross incomes, with duration running to about half the length of the marriage, on a calculation our copy dates to 2019. Two warnings before you use any of that. Nothing behind it has been read: gencourt.state.nh.us returned 403 and the host without the www closed the connection, so 23 percent is our figure rather than New Hampshire's stated rate, and the 2019 date is unchecked with it. And our own two surfaces disagree about the base, one saying gross income and the other adjusted gross, which is the whole of what adjusted means in a support statute. The estimate on this page is a third thing again, and it is not 23 percent: it is our national approximation on the two incomes you enter, it sits below the stated rate for a short marriage, and it passes the rate from a six-year marriage upward.

Key point: The 23 percent our copy states for New Hampshire term alimony is ours rather than the state's stated rate, and the estimate on this page does not use it. Our own surfaces also disagree on whether the base is gross or adjusted gross income.

How New Hampshire awards spousal support

Our New Hampshire record classifies it as a statutory formula state, which means the legislature has written an arithmetic starting point into the statute, so two cases with similar incomes and a similar marriage length should land in a similar place. Here is what that looks like in practice.

Modeled estimate, not a state calculation

This figure is ours rather than New Hampshire's. The arithmetic behind it is a national approximation that runs the same way in every state: 30 percent of the difference between the two incomes, scaled by a factor for the length of the marriage. No New Hampshire document was opened to produce it and no New Hampshire rule is applied inside it. Read it as a planning band rather than a figure a court has committed to, because a New Hampshire judge applying New Hampshire's own law can land somewhere else.

Our record classifies New Hampshire as one of the small group of states that write a spousal support formula into the statute itself. This estimate is not that formula and does not implement it. Nobody here has read New Hampshire's statute, and we would rather tell you that than run arithmetic of our own and put New Hampshire's name on the result. Where the two differ, the statute is right and we are not. A family law attorney licensed in New Hampshire can run the statutory calculation on your own figures, and that is the number to plan around.

A formula state gives the court a calculation to run rather than a list of considerations to weigh. The arithmetic works off the gap between the two incomes, not off either income on its own, which is why a raise for the lower-earning spouse cuts the award as surely as a pay cut for the higher earner does. Close the gap and the figure falls, even when neither household is worse off in total.

The formula is a starting point rather than a ceiling or a floor. A judge can depart from it, and departing generally means putting a reason on the record. That is what makes support in a formula state worth planning around in a way it is not elsewhere. What it does not mean is that every figure on this page is that formula. We have read one state's maintenance statute, Illinois', and there the duration is the statute's own arithmetic while the amount is still ours. Everywhere else both figures are a national approximation applied the same way in all fifty states. The panel above the calculator says which of the two you are looking at, beside every number it returns.

Length of marriage enters twice. It scales the amount, and separately it sets how long payments run. That second effect is the one people underestimate: the difference between a nine-year marriage and an eleven-year marriage is often larger in total dollars than a sizable difference in income would be.

One caveat matters more here than anywhere else on this page. Several states run a formula for temporary support while the case is open and then hand post-judgment support back to the court to decide on the statutory factors. Where that is how the state works, the arithmetic is a good guide to what gets paid during the case and a weaker guide to what gets ordered at the end of it. Check which of the two you are looking at before you plan around the number.

What New Hampshirecourts weigh, in our data's order

These are the 3 factors our New Hampshire record carries, listed in the order it records them. They are the ground a support argument is actually fought on, so the side that documents them is the side arguing where the statute points.

  1. Length of the marriageThe strongest single predictor of both how much support is awarded and how long it runs. Short marriages point toward limited, time-boxed support aimed at getting the lower earner back on their feet. Long marriages point toward larger awards over longer terms, and are where indefinite support is still argued for.
  2. The income difference between the spousesThe figure the calculation is applied to. What matters is the gap, not either income by itself, so a rise in the lower earner's income reduces support just as a fall in the higher earner's does. Two couples with the same household total can reach very different results depending on how that total is split.
  3. Standard of living during the marriageThe benchmark the court measures need against. It is why the same income gap supports a larger award for a couple who lived expensively than for a couple who saved. Documenting how the household actually spent, through statements rather than recollection, is what makes this factor usable in a hearing.

Does conduct matter in New Hampshire?

No. Marital fault does not appear in the New Hampshire factor list, so the analysis runs on need, ability to pay, and the other factors above rather than on who was to blame for the marriage ending. That is worth knowing before you spend money on it: evidence of an affair or of who left first has little purchase on the support question here, and the same money spent documenting the marital standard of living or a career interrupted for the household does far more work.

Grounds are a separate question from support, and the two do not always line up. Our record has New Hampshire letting you file on fault grounds as well as no-fault grounds, our own record rather than New Hampshire's own law on divorce grounds, so conduct could enter the case through the petition itself. It does not follow that it reaches support: conduct is not in the support factor list here, so a fault filing can change the shape of the case without changing the number.

Support and the property split are one conversation

Our record has New Hampshire dividing marital property by equitable distribution, which means the split starts near even and moves with the same kinds of factors that drive support: length of marriage, each spouse's earning capacity, and what each contributed. That is our own record rather than New Hampshire's own property division law. Because the two questions run on overlapping facts, they are usually negotiated together. Trading a larger share of the estate for a smaller or shorter support award is one of the most common settlement structures there is, and it is often the one that gets a case resolved. Real outcomes in a formula state are less spread out than under open discretion, so a planning band means more here than it does elsewhere. That is a fact about the state rather than about this figure. Unless the panel above says otherwise, the estimate is the same national approximation every state on this site gets. A judge can depart from the statutory result anyway, and most support terms are settled by agreement rather than decided at a hearing.

One practical cost sits underneath that trade. Where the asset being swapped for support is a retirement account, dividing it takes a qualified domestic relations order, which runs $500 to $1,500 in New Hampshire on top of whatever else the case costs. Worth pricing in before you agree to take retirement money instead of monthly support, along with the fact that the two are taxed very differently when you eventually draw on them.

New Hampshire spousal support examples

These three examples run through the same New Hampshire calculator on this page, so the figures match what the tool returns for the same entries. Each is a different shape of case rather than a small variation on the one before, because the two things that move support most, the income gap and the length of the marriage, tend to move together in real households.

Read the range, not the middle figure. We draw the band comparatively narrow here, because a formula leaves less room between the high and low outcomes than open discretion does. The width is our judgement about that spread rather than anything the state publishes. In the second example below, the top of the band is about 1.3 times the typical figure.

Example 1: Four-year marriage, modest standard of living

A short marriage with a real but moderate income gap and no caregiving history. This is the case where support is most often brief or refused outright.

Short marriages in New Hampshire may result in limited rehabilitative alimony. Our record classifies New Hampshire as a formula state, so real outcomes there are less spread out than under open discretion. That is a fact about New Hampshire rather than about this number, which is our own approximation and not the state's calculation.

  • The two employment statuses you entered have not changed the estimate above. You had to answer to get here, and whichever answer you picked the figure is the same: we calculate on the income figures you entered and impute nothing to either parent. Courts can impute. Where a judge finds a parent voluntarily unemployed or under-employed, a court may set support on what that parent could earn rather than on what they currently bring in, and an imputed figure is set at or above actual earnings rather than below them. Which way that would move your case depends on whose income gets imputed, and that is the part we cannot answer for you: if it is the paying party's, the figure above tends to sit below what a court would order, and if it is the receiving party's it can move in either direction depending on the state and on the two incomes, so we do not put a direction on it. We have read the imputation provision in Illinois and in no other state, New Hampshire included, so nothing on this page is adjusted for one.
  • Whether the paying spouse has business income has not changed the estimate above. We ask because it shapes the case rather than the arithmetic: business income is the single most argued-about number in a support case, because what a business pays its owner and what a court treats as that owner's income are frequently different figures, and establishing the second usually takes disclosure or a forensic accountant. Nothing in the figures on this page is adjusted for your answer, so do not read the estimate as having priced it in.

Example 2: Twelve-year marriage, one spouse the primary caregiver

The most common shape of a contested support case: long enough that a career was reshaped around the household, not long enough to reach the territory where indefinite support gets argued.

Set the first and third examples side by side and the scale of what marriage length does becomes clear. The estimate moves from around $764 a month running 0.8 to 2 years to around $5,425 a month running 4.8 to 12 years. Part of that is the wider income gap. Most of it is the twenty extra years.

The ceilings below are worked out on the second example above: a twelve-year marriage, $120,000 and $45,000 a year. Enter your own figures in the calculator at the top of this page and it runs the same limits against them.

What New Hampshire law limits

Our estimate runs past a limit this page states for New Hampshire. We have not clamped it, because nobody here has opened the document behind one of them, and a figure clamped to an unread number would look more settled than it is. The limit is worked out below on the figures you entered so you can see exactly how far past it we are.

  • Amount: 23 percent of the difference between the two incomes

    $1,438 a month

    Worked out as 23 percent of $6,250 a month, the difference between the two gross incomes you entered.

    Our estimate runs past this

    Our estimate gives a typical figure of $1,875 a month, $437 above it and a range top of $2,344 a month, $906 above it. We have not brought it down to the ceiling, so the gap is the size of our model's overshoot rather than something a court would order.

    Our New Hampshire page says term alimony runs at 23 percent of the difference between the two incomes. Our estimate starts from 30 percent of that same difference, and a multiplier for the length of the marriage is then applied to it in every case, so the starting rate on its own is never the figure you are looking at. What that produces is a typical figure below the stated rate for a short marriage, above it from a six-year marriage upward, and a range top above it from a three-year marriage upward. That gap is our model rather than New Hampshire's law. We have not opened the statute, as of 2026-08-27, and our own two pages disagree about whether the 23 percent runs on gross income or on adjusted gross income, which changes the answer in every case. Take the rate and its base from the statute or a New Hampshire attorney.

    One caveat on the figure above: our calculator copy states the rate as 23 percent of the difference between the ADJUSTED gross incomes and our guide states it as the difference between the gross incomes. Those are different numbers and we have not opened the statute to find out which is right, as of 2026-08-27, so the ceiling here is worked on gross, which is the higher of our two readings.

    Not read from the statute. This is what our own page states. The document that would settle it is the New Hampshire statute governing alimony and the term alimony formula in it. We tried gencourt.state.nh.us on 2026-08-27 and www.gencourt.state.nh.us returned 403 to a browser user agent; gencourt.state.nh.us without the www closed the TLS connection abruptly.

How long spousal support lasts in New Hampshire

Duration is the question people ask second and worry about first, and it is decided differently from amount. Amount answers what the lower earner needs and what the higher earner can pay. Duration answers a narrower question: how long it should reasonably take the lower earner to get where they can stand on their own, and whether that is realistically possible at all.

The table below runs one couple through the New Hampshire estimate at seven marriage lengths. Incomes are held at $110,000 and $40,000 a year with no children and no health limits, so the only thing changing between rows is how long the marriage lasted.

Estimated New Hampshire spousal support amount and duration at seven marriage lengths, holding income constant
Marriage lengthBandTypical monthlyEstimated durationLikelihood
2 yearsVery short marriage$7000.5 to 1 yearsUnlikely
5 yearsShort marriage$1,1381 to 2.5 yearsPossible

25 yearsVery long marriage$2,4505 to 12.5 yearsVery likely
30 yearsVery long marriage, retirement in view$2,8006 to 15 yearsVery likely

Two things are worth reading off that table. The first is that a five-year marriage and a twenty-year marriage are not the same case with a different number attached: at five years the estimate runs 1 to 2.5 years and support is only possible, while at twenty years it runs 4 to 10 years and is very likely. The second is that the ranges stay wide at every length, because duration is where courts exercise the most judgment and where settlements do the most trading.

Support also ends on events, not only on dates. Across states the usual terminating events are the death of either spouse, the recipient remarrying, and in many places the recipient living with a new partner in a marriage-like arrangement. Retirement in good faith at a normal age is the other common ground for cutting support off or reducing it. Whether New Hampshire treats each of those the same way is a question for a licensed attorney there, and it is worth asking before you sign an agreement rather than after.

Support while the New Hampshire case is still running

New Hampshire imposes no statutory waiting period before a divorce can be finalized, but a contested case here runs about 1.0 years on average against 3 months when both spouses agree. You also need one year of residency in New Hampshire before you can file at all. That stretch of time is the reason temporary support exists. A court can order support early in the case, well before anything final is decided, so the lower-earning spouse is not left covering a separate household on one income for about 1.0 years while the rest gets sorted out. If money is tight now, asking for a temporary order is almost always faster than waiting for the judgment, and the months spent waiting are rarely made up afterwards.

Data pending verification. Some states cap support duration by statute at a set share of the length of the marriage. We have not verified whether New Hampshire does, so the duration column above is our general model rather than a New Hampshire rule, and we are not stating a durational formula we have not checked. Confirm it against the New Hampshire sources below or with a licensed family law attorney in the state.

The kinds of spousal support a court can order

Support is not one thing. States use different names for the categories below and not every state recognizes all of them, but the underlying purposes are consistent, and knowing which one is being discussed tells you what the argument is really about.

Temporary support, while the case is open
Ordered after filing and before judgment, purely to keep two households running while the case is decided. In New Hampshire that window matters more than people expect: a contested case averages about 1.0 years, so this is often the largest block of support anyone actually receives. It ends when the final judgment lands, and it does not commit the court to continuing at the same figure.
Rehabilitative support
Time-limited support tied to a plan: finishing a degree, renewing a license, completing a training program, or re-entering a field after years away. It is the most common outcome for short and mid-length marriages. Because it is tied to a plan, the strongest version of this request comes with the actual program, its length, and its cost rather than a general statement about needing time.
Durational or term support
A set number of years, usually pegged to the length of the marriage, without needing to be tied to a specific rehabilitation plan. This is the category most reform legislation over the past decade has been about, generally replacing open-ended awards with a term the statute caps.
Indefinite or permanent support
Support with no end date written into it, reserved for long marriages where the age, health, or work history of the lower earner means self-sufficiency is not a realistic outcome. Indefinite does not mean unchangeable: it stays modifiable on a substantial change in circumstances, and it generally ends on the usual terminating events.

Data pending verification. Our New Hampshire record does not list which of these categories New Hampshire recognizes by name or what it calls them, so the descriptions above are the general framework rather than a New Hampshire list. We would rather say that than name four New Hampshire categories we have not checked.

How spousal support is taxed

This changed in a way that still catches people out. Under the federal Tax Cuts and Jobs Act, for any divorce or separation agreement executed after December 31, 2018, alimony is not deductible by the spouse paying it and is not taxable income to the spouse receiving it. The federal rule is the same in New Hampshire as everywhere else, because it is federal.

Two consequences follow, and both are worth understanding before you negotiate. Support is now paid out of after-tax dollars, so a given monthly figure costs the payer considerably more than the same figure did before 2019. And the older advice that a large award could be made cheaper by the deduction no longer applies at all. Agreements executed on or before December 31, 2018 generally keep the old treatment, though modifying one can bring it under the current rule if the modification says so.

State income tax is a separate question from the federal one, and it is not something this page models. Check the federal treatment against the IRS guidance below, and check the New Hampshire treatment with a CPA or a licensed family law attorney in the state.

What it costs to argue about support in New Hampshire

Support is the issue most likely to turn a divorce contested, and it is also the one where the arithmetic of fighting is easiest to get wrong. Below are the New Hampshire figures set against what is actually in dispute.

Attorney rate
$225 to $425/hr
Mediation session
$250
Uncontested case
$2,000 to $5,000
Contested case
$12,000 to $40,000

Put those next to the second worked example above, where the estimate came to $1,875 a month, or $22,500 a year. A contested case in New Hampshire runs $12,000 to $40,000, which is the equivalent of roughly 6 to 21 months of that support. Ten billable hours on each side, which a single contested motion can consume, costs $2,250 to $4,250 per side at New Hampshire rates. Two mediation sessions cost $500 shared between you.

The sharper way to read those figures is as a difference rather than a total. An uncontested New Hampshire divorce runs $2,000 to $5,000 and takes 3 months. Contesting it adds $10,000 to $35,000, or roughly 5 to 19 months of the support in that example, and stretches the case to about 1.0 years. That difference is the actual price of the argument, and it is the number to hold against whatever separates your position from your spouse's.

None of that means give up a position worth holding. Where the gap between the two sides is large, where one spouse's income is hard to pin down, or where the marriage was long enough that duration is the real question, representation earns its cost several times over. But where the two positions sit a few hundred dollars a month apart, the arithmetic usually says settle: the fight can cost more than the difference it is about. Our record does not have New Hampshire requiring mediation before a contested hearing, but at $250 a session against a contested case starting at $12,000, it is usually the cheapest serious attempt at a resolution available. That is our own record rather than New Hampshire's own court rules. Our record carries collaborative divorce as available in all fifty states, so it says nothing specific about New Hampshire; whether trained collaborative attorneys practise near you is a local question. Where it is on offer, both sides commit in writing to settle without litigation and share one financial expert instead of hiring two.

New Hampshire spousal support authority

Data pending verification. We have not yet verified the specific statute that carries New Hampshire's spousal support rules, so we are not naming one here. Citing a section number we have not checked would be worse than citing none. The starting points below are New Hampshire's own courts and the institutional sources, and a licensed family law attorney in the state can give you the controlling section.

One thing to be straight about, because it is not visible from the page. This page states the New Hampshire formula our copy states, term alimony at 23 percent of the difference between the parties' adjusted gross incomes with duration at about half the length of the marriage. None of that has been read out of New Hampshire's own law: it came into our copy at the original build and no New Hampshire document has been opened behind it since. It may well be right, and we are not going to present it to you as New Hampshire law while nobody here has read a New Hampshire document saying so. If the exact figure matters to your situation, what would settle it is the New Hampshire statute governing alimony and the term alimony formula inside it, and a New Hampshire family law attorney can read it against your facts.

Alimony in New Hampshire - Frequently Asked Questions

Does New Hampshire have an alimony formula?

Yes, and our estimate is not it. Our data records New Hampshire as one of the small group of states that put an arithmetic starting point in the statute rather than leaving the amount entirely to the judge, and a judge who departs from that starting point generally has to explain why. Nobody here has read the New Hampshire statute, so what this page computes is a national approximation rather than the state's calculation, and it says so beside every figure. One further thing to check: several states run a formula for temporary support during the case and then decide post-judgment support on the statutory factors instead, so confirm which of the two you are looking at.

How is spousal support calculated in New Hampshire?

By a calculation our record says the New Hampshire statute sets out, which nobody here has read and which this page does not reproduce. The statutory factors our New Hampshire record carries are length of the marriage, the income difference between the spouses, and standard of living during the marriage. What our estimate does instead is 30 percent of the difference between the two incomes, scaled by a factor for the length of the marriage, which is the same approximation it applies in every state. Read it as a planning band and take the statutory figure from the statute itself, or from a family law attorney licensed in New Hampshire.

How long does alimony last in New Hampshire?

Duration scales with the length of the marriage more than with anything else. Running the same couple through our New Hampshire estimate at different marriage lengths, a 10-year marriage produces support of 2 to 5 years and a 20-year marriage produces 4 to 10 years. Short marriages under 5 years usually produce brief rehabilitative support or none at all. Long marriages are where indefinite support is still argued for, particularly when age, health, or years out of the workforce mean the lower earner cannot realistically become self-supporting. Support also ends on events rather than only on dates: the death of either spouse, the recipient remarrying, and in many states the recipient cohabiting with a new partner.

How much alimony is typical in New Hampshire?

There is no single figure, because the answer depends on the gap between the two incomes and how long the marriage lasted. As a worked example, a 12-year New Hampshire marriage where one spouse earns $120,000 a year, the other earns $45,000, and the lower earner was the primary caregiver produces an estimate of $1,406 to $2,344 a month, typically around $1,875, running 2.4 to 6 years. Our record classifies New Hampshire as a formula state, so real outcomes there are less spread out than under open discretion. That is a fact about New Hampshire rather than about this number, which is our own approximation and not the state's calculation. Run your own figures in the calculator on this page.

Can alimony be modified in New Hampshire?

Yes. Either spouse can ask the court to modify alimony based on a substantial change in circumstances, such as a significant change in income, retirement, the recipient's remarriage or cohabitation, or a serious health change. New Hampshire courts typically require the change to be material and not anticipated at the time of the original order.

Does fault affect alimony in New Hampshire?

No. New Hampshire does not weigh marital fault in setting alimony. Courts focus on financial need, ability to pay, and the other statutory factors rather than blame for the divorce.

Is alimony tax deductible in New Hampshire?

For divorces finalized after December 31, 2018, alimony is no longer deductible by the payer or taxable to the recipient under the federal Tax Cuts and Jobs Act. This federal rule applies in New Hampshire as it does in every state. Older orders entered before 2019 generally retain the prior tax treatment unless modified.

How we calculate this estimate

Alimony is the least formula-driven number in a divorce, and outside one state this estimate is a national approximation rather than any state's own rule. It works from the gap between the two incomes, scaled by how long the marriage lasted, with the share of that gap set by how your state is recorded as deciding support and by the standard of living during the marriage. The other inputs, employment status on both sides, caregiving history, age and health, and marital fault where your state weighs it, move the factors and the likelihood rather than the arithmetic. The output is a monthly range with a duration range, a likelihood rating, and the specific factors pushing your case up or down.

What the estimate assumes for New Hampshire

  • One state's own calculation is implemented, in half. Six states write a spousal support calculation into their own statute. We have read one of them, 750 ILCS 5/504, and the duration our Illinois calculator returns is that statute's arithmetic rather than our model's: the length of the marriage multiplied by a factor the statute fixes for each year of it, wherever the guideline route reaches the case. The Illinois AMOUNT is still ours, because the statute works it out from net annual income and this calculator collects gross. Everywhere else, both figures are the same national approximation. Every alimony figure we return says which of the two it is, beside it.
  • The share of the income gap our estimate applies depends on which of three groups our record puts your state in, and the marriage-length factor then multiplies it in every case. A formula state takes 30 percent of the gap, which the factor moves to between 12 and 48 percent of it. A discretionary state takes between 22 and 38 percent depending on the standard of living during the marriage, moving to between 8.8 and 60.8 percent. A hybrid state averages the two, landing between 10.4 and 54.4 percent. Those are the figures before any ceiling a state sets, every one of them is ours, and no state publishes any of them.
  • Duration is modeled at about a third of the length of the marriage, with a band around it and a cap at the length of the marriage, in forty-nine states. How wide that band runs depends on the same grouping: a formula or hybrid state gets 20 to 50 percent of the length of the marriage, a discretionary state 13.3 to 66.7 percent. Several of them set duration as a share of the marriage by statute and none of those shares is a third. Illinois is the exception: its ladder runs from .20 below five years to .80 at nineteen and opens up at twenty, we have read it, and our Illinois duration is that calculation rather than the model.
  • State limits are applied in five states and shown without being applied in six more. Delaware, Florida, Kansas, Louisiana and Texas each set a ceiling on the amount or the term, we have read that ceiling out of the state's own instrument, and where our arithmetic ran past it the ceiling is what produced the figure. Florida, Louisiana and Texas are the ones whose ceilings are worked on a base the instrument does not use: their rules measure an income this page does not collect, so what we apply is a generous version of the state's own limit, which is why we are willing to bring a figure down to it and never up to it. Each of those pages says so beside the figure. Massachusetts and Maine's limits are rebuttable presumptions rather than ceilings, so they are shown beside the figure rather than applied to it. Massachusetts carries a second reason on top of that one, set out on its own page beside the figure, and it is the harder of the two: what the rule measures is not what this page collects. Indiana, New Hampshire, New Jersey and Utah have limits our own pages state and nobody here has opened the document behind, so those are worked out on your entries and set beside our estimate without changing it. We do not clamp a number to a figure we could not read. The other 39 states have no limit in our records, which is a statement about our records rather than about their law: where your state limits an amount or a term and we hold nothing for it, the limit still controls and this estimate can exceed it.
  • Which of the three approaches a state takes came into our data at the original build. It has since been checked against the state's own rendered instrument in 4 states, Florida, Illinois, New York and Texas, and each of those pages names the instrument that settled it. In the other 46 it is still our record's classification with no statute behind it.
  • Fault is only factored in for states where our record says fault can affect a support award.
  • The one cost-table figure this page uses is your state's waiting period, and it is our own record rather than a reading of the statute. Nobody here has opened a dissolution statute to check the number, and the same field carries two different things across the fifty states, a wait that runs from filing and a separation requirement that runs from the day you separated. Confirm it with the clerk of court where you will file.
  • The estimate is pre-tax. It does not model how support affects either spouse's tax return.

Where the estimate stops

Outside the Illinois duration, this is our model rather than your state's. In a state that publishes its own calculation the number to plan around is that calculation, and a family law attorney licensed there can run it on your figures. Even where a guideline applies, a judge can depart from it and most support terms are negotiated rather than tried, so treat the range as a planning band rather than a prediction of your order.
