A prenuptial agreement is only as strong as its enforceability. Lafata Law drafts these agreements with litigation in mind — because the attorneys have seen how they get challenged in court.
A prenuptial agreement drafted without attention to enforceability requirements is a document that may not hold up when it matters most. Couples in DuPage County considering a prenuptial or postnuptial agreement need attorneys who understand not just how to draft these documents, but how courts evaluate them during divorce proceedings. Lafata Law brings litigation experience from over 200 cases tried to verdict, providing insight into how prenuptial agreements are challenged — and how to structure them to meet statutory requirements.
A prenuptial agreement is a contract between two people who intend to marry, made in contemplation of marriage and designed to become effective upon marriage. Under the Illinois Uniform Premarital Agreement Act (750 ILCS 10/1 et seq.), these agreements — sometimes called premarital or antenuptial agreements — allow prospective spouses to define their rights and obligations regarding property and financial matters before the wedding takes place.
The agreement must be in writing and signed by both parties. Illinois law does not require consideration (something of value exchanged) for the agreement to be enforceable. The agreement has no legal effect until the marriage occurs.
Illinois law permits prenuptial agreements to address a broad range of financial and property matters. Under 750 ILCS 10/4, parties may contract with respect to:
One critical limitation: a prenuptial agreement cannot adversely affect a child’s right to support. Courts will not enforce provisions that attempt to limit or waive child support obligations.

Enforceability depends on several factors established by statute. Under 750 ILCS 10/7, a prenuptial agreement is not enforceable if the party challenging it proves either of the following:
Involuntary Execution: The challenging party did not sign the agreement voluntarily. This includes situations involving duress, coercion, or undue pressure. Agreements signed days before a wedding with no prior discussion often face scrutiny on this basis.
Unconscionability Combined with Inadequate Disclosure: The agreement was unconscionable at the time of execution, and before signing, the challenging party:
Illinois courts decide unconscionability as a matter of law. An agreement that appears fair at execution may still face challenges if disclosure was inadequate and no written waiver exists.
Additionally, even if a spousal support provision is otherwise valid, a court may override it if enforcement would cause undue hardship due to circumstances not reasonably foreseeable when the agreement was signed.
Attorneys who have litigated divorce cases understand how these challenges arise in court. Megan Lafata’s background in civil litigation, including contract disputes, provides relevant experience in drafting agreements that address potential vulnerabilities.
A prenuptial agreement is executed before marriage and becomes effective upon marriage. A postnuptial agreement is executed after the marriage has already taken place.
While the Illinois Uniform Premarital Agreement Act specifically governs premarital agreements, postnuptial agreements may face additional scrutiny. Once married, spouses owe fiduciary duties to each other. Courts may apply stricter standards when evaluating whether a postnuptial agreement was entered voluntarily and with adequate disclosure.
Both types of agreements serve similar purposes — defining property rights, addressing spousal support, and providing clarity about financial expectations. The timing of execution and the legal relationship between the parties at signing can affect how courts evaluate enforceability.
A prenuptial agreement is only as strong as its enforceability. Drafting an agreement that technically addresses the right topics is not enough if the agreement cannot withstand a legal challenge years later.
Lafata Law’s attorneys have combined experience of over 20 years in litigation, including service as former DuPage County prosecutors. Between both attorneys, they have tried over 200 cases to verdict. This courtroom experience informs how they approach prenuptial and postnuptial agreements — identifying provisions that courts have found problematic and structuring agreements to meet statutory requirements.
Knowledge of DuPage County judges and court procedures provides additional context when advising clients on how local courts have handled similar matters.
Timing matters. Prenuptial agreements signed shortly before the wedding ceremony face increased scrutiny regarding voluntary execution. Courts may question whether both parties had adequate time to review the agreement, consult independent counsel, and make an informed decision.
The best practice is to begin discussions well in advance of the wedding date. This allows time for:
Postnuptial agreements can be considered at any point during the marriage. Couples who did not execute a prenuptial agreement, or whose circumstances have changed significantly, may benefit from a postnuptial agreement that reflects their current situation.
A properly drafted prenuptial or postnuptial agreement can provide both parties with clarity about property rights, financial obligations, and expectations. The value of such an agreement depends on meeting Illinois statutory requirements and anticipating potential challenges.
