If you are planning around a divorce, your beliefs about what courts do tend to shape your strategy as much as the law itself. Those beliefs are often wrong. Most people expect alimony to be awarded in most cases (it is not), expect mothers to almost always get primary custody (the picture is more mixed), and expect equitable distribution to mean a strict 50/50 split (it usually does not).
This guide sets out what we understand about what actually happens, and it is worth being blunt about where that comes from before you read another line.
Every percentage on this page is ours. They came into our data when this site was built. No study, no agency series, no court caseload report and no survey in our records produced any of them, and nobody here has gone back to one. This page used to introduce them as what "recent national-level data shows", what "studies of contested property distribution outcomes" show, and "the clearest finding in the family law research literature" - three attributions to bodies of work that are not cited anywhere here because none of them was read. Those sentences are gone. The figures stay, because the directions they point are well established and widely reported and a reader planning a case is better off with a rough orientation than with nothing, but every one of them is a planning number rather than a measurement, and none of them should be quoted as a statistic.
That is a harder statement than the hedging this page used to carry at the bottom, and it is the accurate one. If a number here matters to your decision, the place to settle it is your own state's court administrator, most of whom publish domestic relations caseload statistics.
Custody outcomes
Historically, most contested custody cases ended with the mother as the primary residential parent, and the trend over the past two decades has been steadily toward shared parenting.
Where we would put the split today:
- About 50% of post-divorce parenting arrangements genuinely shared (each parent with at least 35% of overnights), up from roughly 25% in the 1990s.
- About 35% with one parent as the primary residential parent and the other having frequent contact (every other weekend plus weeknights and longer visits).
- About 15% with one parent holding majority residential time and the other with limited or supervised contact.
The shift toward shared parenting is driven by statutory presumptions, judicial training, and changes in parenting culture. It is more pronounced in cases where parents settle than in cases that go to trial.
States with explicit equal-parenting presumptions
Our records put five states on a presumption favoring equal or substantially equal parenting time when both parents are fit:
- Kentucky: rebuttable presumption that joint custody and equal parenting time are in the child's best interest, under KRS 403.270.
- Arizona: substantial parenting time for both parents is the default unless there is evidence of harm.
- Arkansas: rebuttable presumption of joint custody.
- Missouri: the statute directs courts to consider an equal time arrangement.
- Florida: rebuttable presumption of equal time-sharing.
Two things this list used to say and no longer does. It carried West Virginia as a sixth, against our own record for that state and against the answer in this guide's own FAQ four screens up, and West Virginia is removed. And it dated four of the five to the year the presumption arrived - 2018, 2021, 2018, 2023. Those dates are not held anywhere on this site and were never checked, so they are gone; a legislative history is exactly the kind of detail that reads as authority and costs nothing to invent.
What is left is still our classification rather than a finding: it is our own record rather than those five states' own law. The field these five come from has not been checked against five statutes, and Kentucky's citation is the only one of the five carrying one.
These statutes change what attorneys advise and what cases look like at trial. They do not eliminate disputes, but they shift the burden: the parent seeking less than equal time has to make the case, rather than the parent seeking equal time.
This section used to name three more states as having a milder version of the same thing, and the FAQ named two others as leaning that way in practice without a statute. Both are withdrawn. Placing fifty states on a scale of how far each leans needs a scale, and there is none here; on our own record a state either carries the presumption or it does not.
The "primary caregiver" question
In states without an equal-parenting presumption, who has been the primary caregiver during the marriage carries a lot of weight. Courts apply the "best interests of the child" standard with a list of factors, but in practice the parent who has been doing more of the day-to-day parenting (taking kids to medical appointments, helping with homework, managing schedules) tends to start with a meaningful advantage.
That advantage is generally understood to be more pronounced for younger children and less so for adolescents, and it can be overcome by other factors: relocation, work schedule changes, evidence of impaired parenting. We are not ranking it against the other factors, because that would need a study of decided cases and we have not read one.
Who does more of that day-to-day parenting is uneven and has been narrowing. Among divorcing couples specifically we would put the distribution closer to 60/40 than 80/20, which is our own reading rather than a count of anything.
Income and custody outcomes
Whether income disparity affects custody outcomes is a persistent question, and the general understanding is mixed rather than settled:
- Once parenting involvement is held constant, income is not generally thought to carry much independent weight in a custody decision.
- Looking at raw outcomes, higher-earning parents appear to do somewhat better in contested custody, and the usual explanation is access to better representation rather than judicial preference for higher earners.
- Self-represented parents, in any income bracket, are generally understood to fare worse in custody disputes than represented parents.
We are not citing studies for any of those three, because none has been read for this site, and the previous version of this section attributed all three to studies by name. Read them as the shape of the received view, and note our interest in the third: this site refers readers to attorneys.
The practical takeaway is the same either way: in a contested custody case, the quality of the representation is generally thought to matter more than income directly.
Alimony awards: how often and to whom
This is one of the largest gaps between perception and reality. We would put alimony at about 10% to 15% of divorces nationally, which means most divorces end with no alimony at all.
That range is ours, on the same footing as everything else on this page, and it is worth repeating here because this is the section people quote: it came into our data at the original build, no survey or agency series in our records produced it, and we have not gone back to one. The direction is well established and widely reported; the number is not a measurement.
The cases most likely to produce alimony:
- Long marriages. The likelihood of alimony rises sharply at marriages over 10 years and rises again after 20 years.
- Significant income disparity. A larger gap between spouses' earning capacities increases the likelihood of an order.
- A non-working or under-employed spouse. Especially one who took time out of the workforce for caregiving.
- Older couples nearing retirement. Where one spouse has limited time to rebuild earning capacity.
Recipients are predominantly women, and the share of male recipients has been growing - we would put it at about 8% to 10% of orders now against under 3% a generation ago. That tracks with the growth of dual-earner households and households where the higher earner is female.
How marriage length predicts alimony
A rule of thumb, and ours rather than anybody's data:
| Marriage length | Probability of alimony | Typical duration if awarded | |---|---|---| | Under 5 years | Under 5% | None or under 1 year | | 5 to 10 years | 10% - 20% | 25% to 40% of marriage length | | 10 to 15 years | 25% - 40% | 30% to 50% of marriage length | | 15 to 20 years | 40% - 55% | 40% to 70% of marriage length | | 20+ years | 50% - 70% | Often indefinite (until retirement) |
Where a state writes its duration rule into the statute, the range is narrower than where a judge sets it case by case, which is close to a definition rather than a finding. Whether the underlying pattern differs between the two is not something we have measured.
Property division in practice
Equitable distribution does not mean equal, but in practice it usually approaches equal.
Our own working split of contested property distribution outcomes in equitable distribution states, on the same footing as the rest of this page:
- About 75% of orders between a 45/55 and 55/45 split.
- About 15% between 40/60 and 60/40.
- About 10% more lopsided than that, usually because of separate property claims, dissipation findings, or extreme economic circumstances.
In the nine community property states - Arizona, California, Idaho, Louisiana, Nevada, New Mexico, Texas, Washington and Wisconsin - the legal default is 50/50, and outcomes are generally understood to cluster more tightly around that mark. Deviation requires specific findings, typically separate property contributions or economic misconduct.
The practical implication: do not enter negotiations expecting a major skew. If your case has the elements that produce skewed outcomes (long-term separate property contributions, clear dissipation, very unequal earning capacity), document those elements carefully. If it does not, expect close to even.
What predicts outcomes most strongly
Across all categories of decisions, preparation is what we would put first. Specifically:
- Documentation. Cases with complete financial documentation are decided faster, with less litigation, and closer to what the documentation shows.
- Attorney experience. Family law specialists are generally understood to produce better outcomes than generalists or junior attorneys at comparable case complexity. We have measured nothing here and we refer readers to attorneys, so weigh it accordingly.
- The local judge. Family court is highly judge-dependent. Local attorneys know their judges' tendencies. Out-of-area attorneys rarely do.
- Cooperation level. Cases that settle produce outcomes that survive better. Litigated outcomes are more often modified, appealed, or come back to court.
- Realistic expectations. Parties who enter negotiations with calibrated expectations settle faster and at lower cost. Parties who enter expecting a sweeping victory often spend their way to a worse result.
Self-representation
Self-represented (pro se) parties are generally understood to do worse than represented parties on contested issues, and the size of the gap is where we have least to offer:
- Custody. Our working figure puts self-represented parents roughly 30% to 40% less likely to get their preferred custody arrangement when it is contested. That percentage is ours, and this section used to open by attributing it to a body of published work that is not cited anywhere here because none of it was read.
- Alimony. Lower amounts and shorter durations, we would expect, with no figure attached.
- Property division. Smaller shares of marital assets, same caveat.
The gap is understood to be widest when one party is represented and the other is not, and narrowest when neither is.
None of that means self-representation is always wrong. In a genuinely uncontested case it is the cheapest path and the outcome is whatever the two of you agreed. In a contested one, the cost of an attorney is small against the size of what is being decided. And read that sentence knowing that this site refers readers to attorneys.
Why these numbers are soft
Outcome data on divorce is hard to collect, and that is true whoever is collecting it:
- Settlements are largely invisible. Most divorces settle, often on private terms never filed publicly, so anything drawn from court files is dominated by the contested minority.
- Uncontested outcomes cannot be averaged. Self-determined settlements look like whatever the parties wanted. There is no meaningful national average of them.
- State-by-state coverage is uneven. A few states publish research-grade family court data; most do not.
- Statutes move underneath the data. Any figure predating the recent alimony reforms, the newer custody presumptions or the post-2018 tax rules describes a system that has since changed.
That is the honest reason this page holds working figures rather than statistics. It is also the reason they are worth publishing at all: a reader with a rough orientation negotiates better than a reader with none, as long as nobody pretends the orientation was measured.
How to use this in your case
The most useful applications of a rough outcome picture:
- Calibrate your settlement expectations. If you are demanding terms far from the typical outcome on similar facts, you are likely to be disappointed at trial.
- Decide whether to fight. A case with weak outcome odds and high legal cost is usually a case to settle. A case with strong odds may be worth contesting.
- Identify your real risks and opportunities. Find the figure above that most resembles your case and use it as a starting point, not as a forecast.
- Ask a local attorney what actually happens. Family law specialists who try cases in your county see the local outcome distribution directly, which is more than this page or any national figure can give you.
