Moving to a new state can raise real questions about legal agreements you signed somewhere else. According to the U.S. Census Bureau migration data, about 2.1 percent of Americans moved to a different state in 2024, or roughly 7.1 million people. Many of them arrived with agreements written under very different rules. Not every state has the same rules for whether a prenup is valid, and what worked in one state may not hold up in another.
If you have a prenuptial agreement from another state and your marriage is now heading toward divorce in Illinois, that document may still be valid, but it depends on how it was written and what Illinois law says about it. If you need to review your prenup in 2026, do not wait until a divorce is filed. A Lombard family law attorney who handles prenuptial and postnuptial agreements can help you understand your options.
