Illinois follows equitable distribution under the Illinois Marriage and Dissolution of Marriage Act (750 ILCS 5/503), meaning a judge divides marital property based on fairness — not a guaranteed 50/50 split. A prenuptial agreement gives you and your partner control over how assets and debts are handled, rather than leaving the decision to Cook County Domestic Relations Division.
Chicago's economy spans finance, commodities trading, real estate, and professional services. If you hold a position at a trading firm, own rental properties in Lincoln Park or the Loop, or have a stake in a private practice, a prenup protects those interests. Without one, income and asset growth during marriage becomes marital property subject to equitable distribution.
SignAI generates your Chicago prenuptial agreement with the right legal language automatically — including compliance with the Illinois Uniform Premarital Agreement Act (750 ILCS 10), proper financial disclosure provisions, and terms that Cook County courts have consistently upheld.

Use cases
People in Illinois use SignAI to create Prenups for a wide range of situations. Here are the most popular:
Chicago is a major financial hub with commodities exchanges, hedge funds, and trading firms. A prenup can protect unvested bonuses, deferred compensation, carried interest, and partnership stakes from becoming marital property.
Try it: “I'm a trader in Chicago and need a prenup to protect my deferred compensation and bonuses”
Whether you own a Gold Coast condo, a Wicker Park two-flat, or suburban rental properties, a prenup ensures your pre-marital real estate equity stays protected under Illinois law.

Chicago doctors, attorneys, and other licensed professionals often have significant practice equity and high earning potential. A prenup can address how professional goodwill and practice value are treated during divorce.

Entering a second marriage with children from a prior relationship is common in Chicago. A prenup ensures assets designated for your children remain protected and separate from marital property.

FAQ
Yes. Prenuptial agreements are enforceable under the Illinois Uniform Premarital Agreement Act (750 ILCS 10). The agreement must be in writing, signed voluntarily by both parties, and include fair financial disclosure. Illinois courts regularly uphold properly drafted prenups. SignAI's e-signatures are legally valid under the Illinois Electronic Commerce Security Act and the federal ESIGN Act.
Illinois does not legally require both parties to have independent attorneys, but courts look more favorably on agreements where both sides had legal representation. If one party lacked counsel, a court may examine the agreement more closely for fairness. SignAI generates a professional prenup that both parties can review with their own lawyers.
Yes, but with limits. Illinois courts can set aside a maintenance waiver if enforcing it would cause one spouse undue hardship. The court considers factors like the length of the marriage, each party's earning capacity, and standard of living. A well-drafted maintenance provision that accounts for these factors is more likely to hold up.
Without a prenup, Cook County Domestic Relations Division divides marital property based on fairness factors — not a 50/50 split. This means a judge considers each spouse's contributions, earning capacity, and needs. A prenup lets you define your own division terms, giving both partners certainty about the outcome.
While Illinois has no statutory waiting period, signing at least 30 days before the wedding is a best practice. This demonstrates that both parties had adequate time to review and negotiate the terms without coercion. A prenup signed at the last minute is more vulnerable to legal challenges.
