Divorce after 50: the money guide

Updated September 2026. Every rule links to its official source. How we make our numbers.

Key numbers

  • 36% of US divorces now involve someone 50 or older, up from about 9% in 1990 (Bowling Green State University; Pew Research, 2025).
  • Women's household income drops about 41% after a divorce at 50 or older, roughly double the drop men experience (US Government Accountability Office).
  • Married at least 10 years? You may qualify for up to 50% of your ex's Social Security (SSA).
  • Splitting a 401(k) or pension requires a court order called a QDRO; splitting an IRA does not (IRS).

A divorce at 30 divides furniture and futures. A divorce at 55 divides the retirement you already built, with much less time to rebuild it. That is the whole difference, and it is why the money decisions deserve more attention than the legal ones. This guide walks the four decisions in the order they usually matter, each with a free calculator.

1. The retirement accounts (usually the biggest asset)

For most couples over 50, the 401(k)s and pensions are worth more than the house. The part that grew during the marriage is generally marital property, whichever name is on the account. Start with the Marital Share Estimator to see the marital portion and an indicative range for your state, then read what a QDRO is, because the paperwork that divides a 401(k) has its own rules, its own cost, and its own ways of going wrong.

2. Social Security (the benefit nobody tells you about)

If the marriage lasted at least 10 years, you keep a claim on your ex's record: up to half of his benefit, without reducing his by a cent. Three in ten women don't find out until after decisions are already made. The Ex-Spouse Social Security Estimator gives you a number in about two minutes, even if you don't know his earnings.

3. The house (the decision most people get backwards)

"I keep the house, he keeps the 401(k)" feels fair and often isn't: retirement dollars get taxed on the way out, houses cost money to hold and to sell. Compare the two sides after tax with the House vs. 401(k) Comparison, then read keeping the house at 55 for the carrying-cost math.

4. Health coverage until Medicare

If you were on his employer plan, that coverage ends with the marriage. Between COBRA and the marketplace, the bridge to 65 is plannable, but it can cost more per month than the mortgage. Health coverage to 65 shows the options and typical costs.

Then: how long does the money last?

Once you can sketch the split, the Retirement Runway Calculator answers the real question: at your spending level, with your Social Security start age, how many years are funded, and what monthly budget lasts to 95.
