Yes. Illinois law allows prospective spouses to modify or eliminate spousal maintenance in a written prenuptial agreement. However, a court may refuse to enforce the waiver if the agreement does not satisfy the requirements of 750 ILCS 10/7. Even a valid waiver may not apply if enforcement would cause undue hardship because of unforeseeable circumstances.
At Caesar & Bender, LLP, Chicago prenuptial agreement attorneys Michael Ian Bender and Molly E. Caesar advise clients on drafting, reviewing, and enforcing prenuptial agreements throughout Illinois. Together, they help clients prepare agreements designed to withstand legal scrutiny and represent spouses involved in disputes over maintenance waivers.
This guide explains what the statute requires, what makes a maintenance waiver hold up, when a judge can order support anyway, how partial waivers and caps work, and how these disputes are litigated in Chicago courtrooms.

Illinois Law on Maintenance Waivers
Illinois law allows a prenuptial agreement to modify or eliminate spousal maintenance. Under the Illinois Uniform Premarital Agreement Act (750 ILCS 10/4(a)(4)), prospective spouses can agree to waive or limit spousal support before they marry.
In Illinois, spousal maintenance is the legal term for what many people still call alimony. A maintenance waiver is a provision stating that one or both spouses give up or limit the right to request maintenance if the marriage ends.
For a waiver to be enforceable, the prenuptial agreement must satisfy the requirements of the Illinois Uniform Premarital Agreement Act. Even when the agreement is enforceable, a court can order support under 750 ILCS 10/7(b) if enforcing the waiver would cause undue hardship because of circumstances that were not reasonably foreseeable when the agreement was signed.
Child support is treated differently. A prenuptial agreement cannot adversely affect a child’s right to receive support under 750 ILCS 10/4(b).
What Does Illinois Statute 750 ILCS 10/7(b) Require?
Section 7(b) is a limited safety valve, not a general fairness review. The party seeking support must connect the claimed undue hardship to circumstances that were not reasonably foreseeable when the prenup was signed. Relevant evidence may include the condition and its onset, the parties’ knowledge at execution, current income and property, medical or caregiving needs, ability to work, insurance or other resources, and the amount actually necessary to avoid hardship. Even when the standard is met, the court may order support only to that extent; the rest of the agreement is not automatically displaced.
Challenges to the enforceability of the prenuptial agreement itself are governed by Section 7(a), while Section 7(c) provides that the court decides unconscionability as a matter of law.
| Statutory Provision | What It Requires | Effect If Proven |
|---|---|---|
| 750 ILCS 10/3 | Agreement in writing and signed by both parties; enforceable without consideration | An oral or unsigned agreement is not a valid premarital agreement |
| 750 ILCS 10/7(a)(1) | Party did not execute the agreement voluntarily | Agreement is not enforceable |
| 750 ILCS 10/7(a)(2) | Agreement was unconscionable when executed and the statutory disclosure requirements were not satisfied or waived | Agreement is not enforceable |
| 750 ILCS 10/7(b) | Maintenance waiver causes undue hardship because of circumstances that were not reasonably foreseeable when the agreement was signed | Court can order support only to the extent necessary to avoid the hardship |
| 750 ILCS 10/6 | Amendment or revocation after marriage must be in writing and signed by both parties | An amendment or revocation that is not written and signed does not satisfy Section 6 |
Key Takeaway: Section 7(b) does not let a judge rewrite an unfair bargain. It applies only when a maintenance waiver produces undue hardship traceable to circumstances the parties could not reasonably have foreseen when they signed, and relief is limited to the support needed to cure that hardship.
What Makes a Maintenance Waiver Enforceable in Court?
Whether a maintenance waiver is enforceable depends on the circumstances surrounding the execution of the prenuptial agreement. A challenge under Section 7(a) focuses on how the agreement was signed, while Section 7(b) considers whether later, unforeseeable circumstances caused undue hardship. In In re Marriage of Woodrum, 2018 IL App (3d) 170369, the appellate court confirmed that parties can waive or modify marital rights through a valid premarital agreement.
When voluntariness or unconscionability is disputed, courts look at the facts surrounding the agreement’s execution, including:
- How much time passed between the first draft or negotiations and the wedding date
- Whether each party had a genuine opportunity to hire an attorney of their own choosing
- Whether financial statements, tax returns, or schedules of assets and debts were exchanged
- The parties’ relative bargaining position, age, education, and business sophistication
- Whether the agreement was signed without threats, ultimatums, or last-minute pressure
Was the Agreement Entered Into Voluntarily?
Involuntary execution is the first statutory ground for challenging a premarital agreement under Section 7(a)(1), and the spouse challenging the agreement bears the burden of proof. The court examines the circumstances surrounding execution, including the opportunity to review the agreement, obtain legal advice, and make a meaningful choice before signing.
Presenting a prenuptial agreement immediately before the wedding without enough time for review or legal advice can support a claim that the agreement was not signed voluntarily. At the same time, Illinois courts have held that making a prenuptial agreement a condition of marriage, by itself, does not amount to coercion or duress.
Dated drafts, correspondence, and signed acknowledgments help show how much time each party had to review the agreement and whether there was an opportunity to seek legal advice. Those documents are part of the evidence the court considers, but they do not automatically resolve the issue.
Was There Fair and Reasonable Financial Disclosure?
Financial disclosure is another key part of enforceability under Section 7(a)(2). Unconscionability alone does not make a prenuptial agreement unenforceable. The challenging spouse must also prove that they did not receive a fair and reasonable disclosure of the other party’s property or financial obligations, did not voluntarily waive additional disclosure in writing, and did not have adequate knowledge of those finances.
A closely held company may require tax returns, financial statements, capitalization information, and an explanation of the value used; a full marital business valuation is not always required before marriage, but the disclosure should provide enough information to understand the nature and approximate value of the interest. For couples with substantial or complex holdings, the same documentation can be especially important in a potential high-asset divorce. Each party should retain the signed schedules and a dated copy of the supporting package.
What Is the Difference Between Unconscionability and Undue Hardship?
Section 7(a)(2) and Section 7(b) address different issues. Under Section 7(a)(2), a prenuptial agreement is unenforceable if it was unconscionable when executed and the challenging spouse proves all three disclosure-related conditions set out in the statute. Section 7(b), on the other hand, leaves the agreement in place and addresses whether a maintenance waiver should be enforced.
Unconscionability is evaluated as of the date the agreement was signed and is decided by the court as a matter of law. Procedural unconscionability focuses on the circumstances surrounding the execution of the agreement, while substantive unconscionability focuses on terms that are harsh, oppressive, or inordinately one-sided. A challenge under Section 7(a)(2) also requires proof of the statute’s disclosure-related requirements.
Section 7(b) focuses on events that occur after the agreement is signed. The challenging spouse must prove that unforeseen circumstances caused undue hardship. A later income difference or an agreement that appears unfair in hindsight, standing alone, does not satisfy those requirements.
When those requirements are met, the court orders only the amount of support needed to avoid the hardship. The remaining provisions of the prenuptial agreement, including property division, remain in effect.

Can You Waive Maintenance Partially or Cap the Amount?
Yes. Under 750 ILCS 10/4(a)(4), prospective spouses can modify or eliminate spousal support in a prenuptial agreement. This flexibility allows couples to tailor maintenance provisions instead of choosing between a complete waiver and full statutory maintenance.
Common approaches include a dollar cap on total maintenance, a fixed payment period regardless of the length of the marriage, or a step-down schedule that gradually reduces support over time. Some agreements also include a sunset clause, under which the waiver applies for a set number of years before the statutory maintenance rules take effect.
A maintenance provision can also be tied to specific events, such as the birth of a child, one spouse leaving the workforce, or reaching a stated income threshold. It should also state whether it applies to temporary maintenance during the divorce, post-dissolution maintenance, or both.
Whatever approach the parties choose, the provision should clearly define the amount, duration, and any triggering events. Clear drafting helps avoid disputes over the scope of the waiver, although every provision remains subject to the enforcement requirements of Section 7.
Key Takeaway: Illinois permits caps, step-downs, sunset clauses, and duration limits as alternatives to a complete waiver. Partial provisions often survive challenges more comfortably because they reduce the risk of an unconscionability or undue hardship finding.
What Happens If Your Prenup Omits a Waiver Clause?
If a prenuptial agreement does not address spousal maintenance, either spouse can ask the court to award maintenance in a divorce. The request is decided under the maintenance provisions of 750 ILCS 5/504 rather than the prenuptial agreement. Identifying that issue early in a Chicago divorce helps define the necessary financial discovery and prevents settlement discussions from assuming a waiver that was never written.
The court considers several statutory factors, including each spouse’s income and property, financial needs, earning capacity, the standard of living established during the marriage, the length of the marriage, and contributions one spouse made to the other’s education or career.
For post-dissolution maintenance, statutory guidelines apply when the parties’ combined gross annual income is less than $500,000, and the payor has no obligation to pay child support or maintenance from a prior relationship. The guideline amount equals 33 1/3% of the payor’s net annual income minus 25% of the recipient’s net annual income, subject to a cap ensuring the recipient’s net income plus maintenance does not exceed 40% of the combined net annual income. The duration of maintenance depends on the length of the marriage.
Clear drafting is just as important when a prenuptial agreement includes a maintenance provision. A clause that uses undefined terms or does not specify whether it applies to temporary maintenance, post-dissolution maintenance, or both can create disputes over the scope of the waiver.
How Do Illinois Courts Handle Maintenance Waiver Disputes?
Most maintenance waiver disputes arise during divorce proceedings. In Cook County, those disputes are heard in the Domestic Relations Division of the Circuit Court of Cook County. One spouse typically asks the court to declare the prenuptial agreement, or the maintenance waiver itself, unenforceable.
The parties exchange evidence related to the dispute, including drafts of the agreement, correspondence, financial disclosures, and other documents showing how the agreement was negotiated and signed. Depositions and witness testimony become part of the record when the facts surrounding the agreement are disputed.
If factual disputes remain, the court holds an evidentiary hearing. If the material facts are undisputed, the case can be resolved through summary judgment. The spouse challenging the agreement bears the burden of proving involuntary execution or the combination of unconscionability and the disclosure-related requirements under Section 7(a)(2). A claim under Section 7(b) requires proof that unforeseeable circumstances caused undue hardship. Under Section 7(c), the court decides unconscionability as a matter of law.
Key Takeaway: Maintenance waiver disputes are decided within the divorce case through discovery and an evidentiary hearing, whether the parties pursue mediation or litigation, with the challenging spouse carrying the burden of proof. Fee-shifting clauses in the agreement often make an unsuccessful challenge costly.

Frequently Asked Questions
Is a spousal maintenance waiver automatically valid in Illinois?
No. The party resisting enforcement may challenge the agreement under Section 7(a) and carries the burden of proving the applicable statutory grounds. Section 7(b) may also permit limited support when an otherwise enforceable waiver causes undue hardship because of circumstances that were not reasonably foreseeable at execution.
Can a prenup waive maintenance for a stay-at-home spouse?
A maintenance waiver can apply even if a spouse later stays home. Enforcement still depends on Section 7(a), and Section 7(b) may permit support if unforeseen circumstances cause undue hardship.
What if my spouse didn’t have a lawyer review the prenup?
Lack of independent counsel does not automatically invalidate a premarital agreement. However, the opportunity to obtain advice and understand the agreement may be relevant when the court evaluates voluntariness and procedural unconscionability.
Can a waiver be challenged years after signing?
Yes. Challenges commonly arise during dissolution proceedings, which may occur many years after execution. Voluntariness and unconscionability are evaluated as of the execution date, while Section 7(b) considers later circumstances. Any applicable statute of limitations is tolled during the marriage, although equitable defenses such as laches and estoppel remain available.
What evidence do courts look at to prove unconscionability?
Judges consider the financial disclosures attached to the agreement, drafts and their dates, attorney correspondence, the interval before the wedding, each party’s education and business sophistication, and how one-sided the terms were when signed. Testimony from the drafting attorneys is common.
Can a maintenance waiver be modified after marriage?
Yes. Under 750 ILCS 10/6, an existing premarital agreement may be amended after marriage only through a written agreement signed by both spouses.
