Why Divorce Filings Spike in March and August: The Seasonality of Splitting Up
March 7, 2026
Divorce doesn’t file evenly across the calendar. Court filing data shows a consistent, repeatable curve — two real peaks, in March and August — and the reasons behind each are different enough that “the seasonality of divorce” is really two separate stories, not one.
The real curve
Rather than a steady drip of filings throughout the year, the data shows a clear dip around the winter holidays, then a sharp climb into a March peak, a summer lull, and a second, separate rise into August.
Why March, specifically
The most common explanation isn’t romantic — it’s practical and calendar-driven. Couples who decide during the holiday season not to divorce yet, for the kids’ sake or to avoid disrupting family gatherings, follow through once the holidays are safely behind them and the new year’s resolve has had a few months to firm up. January’s post-holiday intent becomes March’s actual filing, once attorneys are consulted and paperwork is prepared.
Why August, separately
The August peak lines up with the end of the school year cycle — filing before a new school year starts, so custody and living arrangements can settle before children begin a new grade, rather than disrupting a school year already in progress.
What this reveals about how divorce actually happens
Both peaks point to the same underlying pattern: divorce is rarely a single sudden decision. It’s a decision made privately, then delayed deliberately around external logistics — the holidays, the school calendar — before it becomes a court filing. The paperwork date and the actual decision date are often months apart.
What this means if you’re the one deciding
Recognizing this pattern doesn’t change the decision itself, but it does reframe the idea that timing a filing around practical considerations — kids’ school year, family events — is somehow unusual or calculated. The data suggests it’s actually the norm, not the exception.
