The March effect: Why divorce filings spike every spring

Divorce filings in the U.S. follow a predictable seasonal pattern, peaking in March and August every year, and researchers say the timing reveals something important about how people actually end marriages. In this article, Skillern Firm Divorce & Child Custody Lawyers, a Texas family law firm, examines the data behind divorce filing trends in the U.S. and what these seasonal patterns may reveal about how couples approach the decision to end a marriage. Every year, family law attorneys start getting busier around the same time the weather changes.

The pattern has a name in legal circles. Some call it "divorce season,” referring to the springtime surge in marital dissolution filings that researchers and practitioners have tracked for years. Whatever you call it, the data behind it is more consistent and more revealing than most people realize.

The Myth of the ‘Divorce Month’

January gets most of the press. Each new year, headlines declare it the yearly "Divorce Month," suggesting that couples who clashed over Christmas or waited to preserve one last holiday season line up at their attorneys’ offices come Jan. 2.

While divorce inquiries might increase in January, the actual filings tell a different story. Some divorce filings do begin to increase during the first month of the year, but the data shows they don't peak until March.

That distinction matters. Divorce, the data suggests, is almost never impulsive.

What the Research Actually Shows

University of Washington sociologists Julie Brines and Brian Serafini conducted what is believed to be the first quantitative study of seasonal divorce filing patterns, analyzing filings across Washington state from 2001 to 2015. They found that filings consistently peaked in March and August every single year across the 14-year period studied.

The pattern held even after accounting for other seasonal variables like unemployment rates and housing market conditions. When the researchers tested whether family-adjacent court filings, such as guardianship rulings, followed a similar pattern, they found that they did. Property claims, which carry no family-ritual dimension, did not. That finding helped confirm what the researchers suspected: The calendar of divorce filings tracks the calendar of family life.

Brines and Serafini also tested the pattern across four additional states (Ohio, Minnesota, Florida, and Arizona), which varied significantly in demographics and economic conditions, particularly during the recession years. Despite those differences, the biannual filing pattern persisted in each one.

Holiday Pressures

To understand why spring filings surge, it helps to first understand what happens in the months before. According to Brines, winter and summer holidays function as culturally important periods for families. These are times when filing for divorce feels inappropriate, even taboo. Struggling couples often treat these stretches as a last chance to spend Christmas together or take one more family vacation. They might have hope that these opportunities will change something.

"People tend to face the holidays with rising expectations, despite what disappointments they might have had in years past," Brines said. "They represent periods in the year when there's the anticipation or the opportunity for a new beginning."

That optimism competes with the reality of the holidays for many people. A November 2025 poll from the American Psychiatric Association found that 41% of Americans expect elevated stress during the holiday season, with finances, family dynamics, and grief ranking as the leading causes.

For couples already carrying tension into Thanksgiving or Christmas, the logistics of travel, competing family obligations, and financial pressure often do not help to heal a marriage. A 2024 study conducted by Qualtrics on behalf of Intuit Credit Karma found that nearly half of Americans (49%) feel more stressed about finances during the holidays, with 44% reporting pressure to spend more than they can afford. When January credit card statements arrive, couples managing a fragile financial picture are often forced into disputes they can no longer put off.

Why Increased Filings Can Take Until March

The lag between the holiday breaking point and the March filing peak is not random. Brines notes that couples need time to get finances in order, find an attorney, and get the courage to actually file. This all creates a natural delay between the decision and the action that can easily take months.

There may be psychological factors at work, too. Researchers from Johns Hopkins have noted that suicides also tend to peak in spring, while many people assume suicides peak in the winter, similar to divorce. Whether the same mechanism drives divorce filings is unknown, but the timing correlation is consistent year over year.

The August Counterpart

The early spring spike has a late-summer mirror. August filings follow similar logic: A summer family vacation that was supposed to reconnect a couple instead confirmed what one or both partners already knew. Brines and Serafini note that the August surge typically follows summer vacations that did not go as hoped, with parents deciding they want to begin proceedings before their children start a new school year.

Brines believes the approaching school year may actually accelerate the timing for couples with children, creating a practical deadline that pushes the decision from "someday" to "now."

What the Pattern Reveals

Taken together, the spring and summer filing peaks show that divorce is rarely impulsive. Brines and Serafini noted that the data suggests that most people who file in March made their decision somewhere around December or before and spent months preparing and gathering the resources to move forward.

The consistent seasonal pattern, Brines concluded, reflects a "domestic ritual" calendar that governs family behavior. This indicates that rather than holidays causing divorce, they delay it.
