Alimony can feel abstract until it becomes part of a real divorce case. Then the questions get personal very quickly: How do courts decide who pays, how much, and for how long? The short answer is that judges usually look at a group of financial and practical factors rather than one simple formula.
In many states, alimony—often called spousal support or spousal maintenance—is designed to address economic unfairness that can follow a divorce, especially when one spouse earned more, paused a career, handled more caregiving, or relied on the marriage financially. State laws vary, and some states use specific statutory factors while others give judges broader discretion. The American Bar Association’s 2025 50-state chart on divorce and alimony and its 2026 family law charts overview both highlight just how state-specific these rules can be.
In this post, you’ll learn 10 common factors courts consider when awarding alimony, why those factors matter, and what kinds of evidence often shape the outcome. If you want a broader foundation first, it may help to start with this overview of how spousal support works, including types, duration, and when payments may end.

Unlike child support, which often relies on guideline calculations, alimony is frequently more individualized. The ABA notes that courts usually have more leeway in alimony decisions than in child support decisions because spousal support is closely tied to the facts of a particular marriage and divorce. The ABA’s family law resource on awarding alimony and support describes that broader discretion.
That flexibility can cut both ways. It allows a court to consider the real story behind a family’s finances, but it also means documentation matters. Recent appellate updates collected by the ABA show courts reversing or questioning support rulings where trial courts failed to make findings about income, expenses, standard of living, or earning capacity. See, for example, the ABA’s November 2025 case update and April 2026 case update.
One of the first things many courts examine is how long the marriage lasted. In general terms, a shorter marriage may be less likely to lead to long-term support, while a longer marriage may make ongoing alimony more plausible.
For example, Massachusetts law lists the length of the marriage as a required factor in setting the form, amount, and duration of alimony, and its statute also ties durational limits to marriage length in many cases. See Massachusetts General Laws Chapter 208, Section 53 and Section 49. Other states use similar frameworks even if the details differ.
Why it matters: a long marriage often reflects a deeper economic partnership. Over time, couples may make choices that are hard to unwind after divorce—one spouse taking fewer promotions, leaving the workforce, moving for the other spouse’s career, or becoming financially dependent in ways that developed gradually.
Courts nearly always look at current income, but they also tend to look beyond a paycheck. Judges may review wages, bonuses, self-employment earnings, investment income, retirement income, and other available resources.
Ohio’s spousal support statute, for example, directs courts to consider the income of the parties, from all sources, along with relative earning abilities and assets and liabilities. That appears in Ohio Revised Code 3105.18. Massachusetts likewise directs courts to examine income and related financial realities in setting support under Chapter 208, Section 53.
Why it matters: alimony is often about whether one spouse has a meaningful financial shortfall and whether the other has meaningful capacity to contribute. A court may also compare post-divorce living situations rather than focusing on gross income alone.
This is one reason detailed financial records can become central. In many divorces, the difficult question is not whether money exists, but how much is truly available after taxes, debt service, business expenses, and other obligations.
A spouse’s current income is only part of the picture. Courts often consider earning capacity—what someone can realistically earn based on education, work history, training, health, and the local job market.
Massachusetts explicitly lists employment and employability, including employability through additional training if necessary, as a factor in alimony decisions under Section 53. Ohio similarly includes relative earning abilities and the time and expense necessary for a spouse to get education, training, or job experience in Section 3105.18. The ABA’s Family Advocate issue on income notes that many states allow courts to impute income based on earning capacity in support cases.
