Global Trend Sees Median Marriage Length Before Divorce Hit Record High

For a marriage to end, a couple must first be able to afford the exit—and right now, millions cannot. The financial mechanics of separating one household into two have become a binding constraint on divorce, fundamentally altering the timeline of modern relationships. When couples sit down at the kitchen table to divide their lives, the math of rent, mortgages, and childcare often stops the process in its tracks. According to new data from the Office for National Statistics (ONS), the median duration of a marriage ending in divorce in England and Wales reached a record high of 13.0 years in 2025. This marks the longest average marriage lifespan before dissolution since records began in 1963, representing a sharp increase from the historic low of 8.9 years recorded in 1985.[3][4]

The shift is not isolated to a single demographic, but rather reflects the heavy economic weather couples are currently navigating. Inflation, rising mortgage rates, and the escalating costs of daily life have made the prospect of separation financially daunting. Rebecca Aston-Jones, a senior associate at the law firm Clarke Willmott, noted that the rising cost of living is keeping unhappy couples together. "One of the main factors discouraging people from pursuing a divorce is the significant financial pressure that comes with establishing and maintaining two separate households," she stated.

Legal professionals observe that couples are increasingly hesitant to face the financial consequences of a split. Lisa Pepper, a partner and specialist divorce lawyer at Osbornes Law, pointed out that while the legal process of divorce is more accessible than it has been in the past 60 years, the economic barriers remain high. She suggested that a "less romantic reason" for the record-breaking marriage durations is simply that couples cannot afford the alternative, prompting many to try mediation or couples therapy before choosing the "nuclear option."[4]

The data reveals a clear generational shift in relationship longevity. Among couples who married in 2015, only 16.3 percent had divorced before their 10th wedding anniversary. In contrast, for those who married in 1995, nearly a quarter (24.7 percent) had dissolved their marriages within the first decade. This downward trend in early divorce suggests that newer cohorts are either navigating early marital challenges more successfully or are more constrained by the economic realities of the 2020s.[4]

The trend of extended marriage durations applies across different partnership structures. Same-sex civil partnerships and marriages are also seeing record lengths before dissolution. In 2025, the median duration at dissolution was 13.7 years for male couples and 13.6 years for female couples. Meanwhile, the overall divorce rate has remained stable at 8.4 per 1,000 married people, which sits well below the peak levels seen in the 1980s and 1990s, when approximately 150,000 divorces occurred annually compared to the 105,002 registered in 2025.[4]

While the extended duration of marriages might appear as a victory for relationship stability, family lawyers caution against purely romantic interpretations. The introduction of no-fault divorce in 2022—which accounted for 94.2 percent of legal partnership dissolutions in 2025—was expected by some critics to trigger a spike in separations. Instead, the 20-week mandatory reflection period built into the new legislation has provided couples with necessary time to untangle increasingly complex financial assets, from pensions to property, which accumulate over longer marriages.[4]

The global picture mirrors these domestic findings, showing that longer marriages before divorce are part of a wider trend. Across various developed nations, the median length of marriages ending in divorce hovers around the 12-to-13-year mark. In the United States, for instance, the median length of a marriage ending in divorce is approximately 12 years, with about 40 percent of divorces occurring within the first decade. The data challenges the outdated but persistent myth that half of all marriages end in divorce, highlighting instead that higher education and greater financial stability correlate strongly with lower divorce rates.[1][2]

The financial complexity of untangling a 13-year marriage is significantly higher than that of an 8-year marriage. Couples divorcing later in life must navigate the division of deeply intertwined assets, including joint mortgages, retirement funds, and investments. This complexity often requires independent valuations and careful legal navigation, further extending the timeline from the initial decision to separate to the final legal dissolution.[1][4]

The record-high median marriage length reflects a complex intersection of economic pressure and evolving relationship dynamics. While some couples are genuinely finding ways to sustain their marriages longer through therapy and mediation, others are simply trapped by the math of the modern housing market. The decision to divorce is no longer just an emotional one; it is a rigorous financial calculation that many couples are currently unable to balance, forcing them to redefine the boundaries of their relationships while remaining under the same roof.[4]
