Baby boomers are having second thoughts about “till death do us part.” Instead of waiting, a growing share of people over 50 are going to the courthouse. And for adults over 65, divorce is no longer just happening, it’s accelerating: it has tripled, even though divorce rates among younger adults have fallen since 1990.

The broader divorce-rate context shows how unusual this age shift is. Overall, the U.S. divorce rate peaked at 22.6 per 1,000 married women in 1980 and has generally declined, hitting 14.2 per 1,000 in 2024. But the age breakdown flips the story. Divorce has fallen among people in their 20s and 30s since 1990, while for people over 50 it has doubled, and for those over 65 it has tripled. Nearly 40% of divorces now involve adults over 50. Translation for anyone overseeing financial, legal, or wealth platforms: the “silver split” wave is reshaping what retirement and inheritance actually mean for households entering late life.

Why this matters goes beyond heartbreak. Longer life expectancies extend the time people may spend in an unhappy marriage, increasing the incentive to exit later rather than endure longer. Middle-class households also increasingly have two incomes, which can raise the sense of financial independence needed to take a leap. And stigma has declined, making it socially easier to divorce than it used to be. The source frames these drivers as hard to pin down exactly, but divorce attorneys say they are seeing older clients show up with more frequency.

For example, Frank Perrone, cochair of the matrimonial law practice at Tarter Krinsky & Drogin in New York, says he is working on two gray divorce cases, including one where both parties are in their 80s. In that case, the wife wants to travel and spend money, while the husband does not want to leave the house. The conflict has created financial animosity, and the couple is moving toward separation and splitting everything up. This is a pattern executives should notice: late-life divorce is not just a custody conversation. It turns into a high-stakes, multi-asset financial restructure with real emotional friction.

The financial mechanics are where the chaos lives. For older couples, high-earning years are often behind them. If one spouse has not been working for years, getting back into the workforce can feel daunting. Perrone highlights that the major issues often focus on income and retirement assets, including pensions, 401(k)s, and annuities. “The biggest asset may not be the house anymore,” he says, noting that retirement accounts become more central in later-in-life splits. He also calls out the downstream effect: in long-term marriages, divorce can mean restructuring “almost an entire lifestyle.”

Second-order effect: the expense math of being single is brutal, especially in retirement. The source points out that a single-person household is much more expensive to run than a two-person household. Retirement accounts can be slashed, and newly single Americans may have to reevaluate how they will spend their time and money. Women may feel this hardest. Research cited in the source shows women experience a 45% decline in their standard of living compared to a 21% decline for men. Traditional gender roles still echo in late-life finances: women may have fewer earnings and less career advancement because years at home caring for children can dampen income growth. They also have longer life expectancies, meaning retirement income needs can last longer.

That’s why this trend is as much a financial education and systems problem as a legal one. Sharon Klein, president of family wealth at Wilmington Trust in New York and head of its divorce advisory practice, says lingering traditional gender roles can leave women without a clear picture of their finances, even including basic items like credit histories. “Women need to get educated about what they have,” Klein says. And while support from friends and family matters, their networks are not equipped to handle the administrative nightmare of late-life divorce: tax issues, legal issues, investment decisions, and the risk of making decisions too quickly.

The “paperwork trap” is real. Laws vary state by state and each divorce is unique, but couples often underestimate how many moving parts there will be: taxes, illiquid assets, and estate planning. Experts warn that people frequently update their wills post-divorce to remove former spouses and miss other accounts whose beneficiaries must also be changed, such as trusts, 401(k)s, and life insurance. Another critical risk is updating powers of attorney, since no one wants an ex deciding whether to pull the plug at a hospital.

The source includes concrete examples showing how these misses can turn “fair” splits into unfair outcomes. Jeff Judge, managing partner at Chesapeake Financial Planners, describes a situation where an equal split was not equal due to different tax liabilities on different assets. He also recalls a client who only realized after her husband died that she had never changed the beneficiary of his life insurance policy, resulting in “hundreds of thousands of dollars” going directly to the ex-wife. Craig Parker, assistant general counsel of Trust & Will, emphasizes that it is “very common in a gray divorce” for people to leave assets in the ex’s name even years after divorce, and even if they paid a lot during the divorce. Parker adds that “The estate plan is a separate stop,” which is a blunt way of saying divorce settlements do not automatically cleanse the rest of your financial system.

Executives should also consider what happens when divorce drags or gets contested late in life. Sophie Spears, an associate attorney at Mosberg Sharma Stambleck Gross LLP in New York, says adult children sometimes push parents to fight divorce in court rather than mediate or settle. Spears calls court “inconvenient, uncomfortable, and invasive,” and also expensive. Separately, the source notes that prenuptial agreements weren’t as common decades ago, and even when they exist, people sometimes cannot find them. Families may also have trouble proving inherited property is only theirs because they no longer have a copy of the will. In other words: later life divorces create logistical landmines when records are missing and agreements are outdated.

Put it together and you get the strategic stake for leaders in wealth, finance, and legal ecosystems. As the U.S. enters the largest intergenerational wealth transfer in history, gray divorce may quietly reroute trillions of dollars and reshape retirement many people have envisioned. That means boards and executives should treat this like infrastructure. When divorce becomes more common after 65, the “end of the marriage” turns into a multi-asset, multi-stakeholder redesign of retirement, inheritance, taxes, and beneficiaries. The households involved are not hypothetical. They are the ones approaching the moments your products, services, and risk models are built to support.
