Illinois adopted the Uniform Premarital Agreement Act under 750 ILCS 10/1 through 10/7. Illinois follows equitable distribution under the Illinois Marriage and Dissolution of Marriage Act (750 ILCS 5/503), meaning courts divide marital property based on fairness — not a 50/50 split. A prenup lets you and your partner decide property division terms yourselves.
Whether you're a Chicago commodities trader protecting investment returns, a Springfield professional with a growing medical practice, or a Naperville couple entering a second marriage, an Illinois prenup gives you clarity. Chicago's high-value real estate market and the state's equitable distribution rules make property division particularly contentious without a prenup.
SignAI generates your Illinois prenuptial agreement with proper legal language — including compliance with 750 ILCS 10, equitable distribution considerations under 750 ILCS 5/503, and governing law clauses for Illinois courts.

FAQ
Yes. Illinois adopted the Uniform Premarital Agreement Act (750 ILCS 10/1–10/7). The agreement must be in writing, signed voluntarily by both parties, and supported by fair financial disclosure. Illinois courts regularly enforce prenups that meet these statutory requirements.
Illinois law permits modification or waiver of spousal maintenance in a prenuptial agreement. However, courts may refuse to enforce a waiver that would cause undue hardship. Under 750 ILCS 5/504, maintenance is evaluated based on factors like income disparity and marriage duration — a prenup can modify these considerations.
Under 750 ILCS 5/503, non-marital property includes assets owned before marriage, inherited property, gifts from third parties, and property acquired by exchange of non-marital property. A prenup can expand this list by designating additional categories of property as non-marital.
Yes. Under Illinois UPAA (750 ILCS 10/7), a prenup is unenforceable if one party didn't receive fair and reasonable disclosure and didn't voluntarily waive disclosure. SignAI includes financial disclosure schedules to meet this requirement.
Yes. Under 750 ILCS 10/6, a prenuptial agreement can be amended or revoked after marriage by written agreement signed by both parties. The modification must also be voluntary and supported by fair disclosure. A postnuptial agreement can address changed circumstances.
