In the United States 54 percent of cohabiting partners are not married to each other. Divorced individuals enter these unions after an average of 1.8 years. Multiple studies link the pattern to roughly twice the risk of separation and higher odds of depressive symptoms than marriage.
Key Takeaways
- In the U.S., 54% of cohabiting partners were not married to each other (cohabitation prevalence within all couples)
- The average duration between divorce finalization and entering a cohabiting union among divorced individuals was 1.8 years in a longitudinal study of U.S. families (2010–2016 data collection)
- For divorced parents in the U.S., the risk of starting a cohabiting relationship was highest within the first 2 years after divorce (hazard peak in early post-divorce period)
- In a nationally representative U.S. study, cohabiting after divorce was associated with lower average relationship stability than marriage (higher separation rates for cohabitors compared with married couples)
- Cohabiting couples were about 2x as likely to experience relationship dissolution as married couples in a large U.S. comparative analysis (relative dissolution risk)
- Divorced individuals who cohabit show higher odds of depressive symptoms than non-cohabiting divorced individuals (odds ratio in the study’s model)
- Cohabiting after divorce can increase household income volatility; a study found that cohabiting was linked to greater changes in household resources compared with marriage (directional findings with measured outcomes)
- In the U.S., fewer legal protections apply to unmarried cohabiters than spouses—only 17 states (and DC) provide comprehensive domestic-partner-equivalent protections across major legal domains as of 2024 (state policy count)
- As of 2024, 32 U.S. states have no specific laws granting inheritance rights to unmarried cohabiters (state-by-state legal overview)
- 39% of divorced adults reported having discussed finances before moving in with a new partner (planning behavior)
- Among adults who have experienced divorce in the U.S., 44% reported wanting to keep assets separate when living with a new partner (asset-separation preference)
- Remote legal consultation adoption reached 41% among law-firm clients in 2023 (survey-based adoption share)
- The global family services and legal assistance market for legal documentation and advice was valued at $72.6 billion in 2023 (industry market estimate)
Many divorced Americans start cohabiting quickly, but it often brings less stability and weaker legal protection.
