Prenuptial Agreement Lawyer Chicago, IL
A prenuptial agreement is a contract entered into by two people before they marry. It sets out how assets, debts, and financial obligations will be handled during the marriage and in the event of divorce or death. In Illinois, prenuptial agreements are governed by the Illinois Uniform Premarital Agreement Act, which outlines what these contracts can and cannot include, and what makes them enforceable. For an agreement to hold up in court, it must be entered into voluntarily, with full financial disclosure from both parties, and without fraud, duress, or unconscionable terms.
What a prenup covers depends entirely on the couple’s situation. Some agreements address real estate and business ownership. Others focus on protecting separate property or defining how maintenance will be handled if the marriage ends. Every agreement we draft starts with an honest conversation about what matters most to you.
Types of Prenuptial Agreement Cases We Handle in Chicago
Our firm works with individuals at all financial levels and in all kinds of relationships. Whether you own a business, have children from a prior marriage, or simply want clarity going into a new chapter, we handle the full range of premarital and marital agreement matters.
- Prenuptial agreements. We draft premarital agreements covering property division, separate versus marital assets, debt allocation, business interests, inheritance rights, and financial obligations during the marriage. Each agreement reflects the specific circumstances of the people involved.
- Postnuptial agreements. Couples who didn’t enter marriage with an agreement sometimes want to establish one afterward. A postnuptial agreement addresses the same financial issues as a prenup and can be entered into at any point during the marriage.
- High net worth prenuptial agreements. When significant assets are involved, including closely-held businesses, investment portfolios, real estate holdings, or inherited wealth, the drafting process requires greater precision. We have substantial experience structuring agreements around complex financial situations.
- Cohabitation agreements. Unmarried couples who live together and share finances benefit from a written agreement that defines property rights and financial obligations. These agreements serve a similar function to a prenup but apply outside of marriage.
- Civil union agreements. Illinois recognizes civil unions, and parties entering into a civil union have the same right to premarital agreements as those entering into marriage. We handle the full range of agreement work for civil union couples.
- Agreement review and negotiation. If your future spouse has presented you with a draft agreement, we review it for fairness, enforceability, and your legal exposure before you sign anything. Coming in with a draft someone else prepared is one of the most common situations we handle.
- Legal separation. When couples decide to separate rather than divorce, a formal separation agreement defines financial and property arrangements going forward. We handle these alongside our premarital agreement practice.
- Prenuptial agreement enforcement and challenges. If a prenuptial agreement is being enforced against you in a divorce, or if you believe an agreement you signed wasn’t entered into fairly, we handle both enforcement and challenge proceedings. The validity of these agreements turns on specific legal questions, and the outcome matters significantly.

Experience Drafting and Litigating Family Law Agreements
Olga A. Allen has focused exclusively on family law since 2007 and has handled prenuptial and postnuptial agreement matters across a wide range of financial circumstances, from straightforward property protection to agreements involving business ownership, prior marriage obligations, and significant inherited assets. Her work spans both negotiated settlements and contested litigation, which means she understands what makes an agreement durable and what makes it vulnerable.
In 2024 and 2025, Ms. Allen was named a Super Lawyer by Super Lawyers Magazine, a distinction awarded to only 5% of attorneys in Illinois based on professional achievement and peer recognition. She also held the Rising Star designation every year from 2016 through 2022. She is fluent in Polish and has a strong commitment to serving Chicago’s Polish community.
Beyond Ms. Allen, our firm brings substantial depth to this practice area. John Kay has practiced exclusively in family law since 1992, with more than 30 years of experience navigating financial disputes in Chicagoland courts. Brian J. Hurst has been with the firm since 2007 and has built a practice focused entirely on matrimonial and family law, including complex financial matters. Together with their colleagues, these attorneys have handled prenuptial agreements across every level of financial complexity this city has to offer.
A Track Record That Extends to Appellate Courts
Prenuptial agreements occasionally get challenged in divorce proceedings, and when they do, the outcome can turn an entire case. Ms. Allen has prevailed in both the Illinois Appellate Courts and the Illinois Supreme Court through her appellate practice, a record that reflects an ability to handle family law questions at their most complex. That appellate depth is not something most family law firms can claim, and it matters when an agreement’s validity is at stake.
Our firm’s appeals practice is a genuine asset for clients whose matters extend beyond the trial court level.

Understanding Prenuptial Agreements in Chicago
Key Provisions and What They Do
A well-drafted prenuptial agreement addresses the financial relationship between the parties clearly and specifically. Common provisions include:
- Separate property designation. Identifying assets each party brings into the marriage and establishing that those assets remain separate, not subject to division in a divorce.
- Business ownership protections. Defining how a business interest is treated during the marriage and in the event of divorce, including whether appreciation in value is marital or non-marital property.
- Debt allocation. Clarifying which debts belong to which party and ensuring one spouse is not liable for the other’s pre-marital obligations.
- Inheritance and estate planning integration. Addressing how the agreement interacts with each party’s estate plan, which matters especially when either party has children from a prior relationship.
- Maintenance provisions. Illinois law permits prenuptial agreements to address spousal maintenance, including whether it will be paid, in what amount, and for how long, subject to certain limitations.
Important Aspects of Your Prenuptial Agreement
A prenuptial agreement that’s rushed, poorly drafted, or signed under pressure is far more likely to be challenged later.
- Both parties need independent legal counsel. An agreement is far more defensible when each party has their own attorney. Courts look at whether both sides had the opportunity to understand what they were signing.
- Full financial disclosure is non-negotiable. Illinois law requires complete disclosure of assets and liabilities before a prenuptial agreement can be enforced. An agreement signed without full disclosure is vulnerable to challenge.
- Timing matters. An agreement presented days before a wedding, with no time for review or negotiation, raises serious enforceability concerns. Starting this process months in advance protects both parties.
- Provisions must be legally permissible. Some terms, including any provisions that affect child support or that are grossly unfair at the time of enforcement, won’t hold up. A knowledgeable attorney helps you understand where those lines are.
Typical Prenuptial Agreement Timeline
The process typically unfolds in stages, and the timeline depends on the complexity of the financial issues involved:
- Initial consultation: Both parties, each with their own attorney, discuss the scope of the agreement and what issues need to be addressed.
- Financial disclosure: Each party provides a complete picture of their assets, income, debts, and obligations. This step cannot be skipped.
- Drafting: The agreement is drafted, reviewed, and negotiated between both parties and their respective counsel.
- Review period: Both parties have adequate time to review the final draft, ask questions, and request changes before signing.
- Execution: The agreement is signed in accordance with Illinois law, with each party’s signature witnessed and notarized.
What to Bring to Your Prenuptial Agreement Consultation
Before your first meeting, gather the following:
- A general inventory of your assets, including real estate, bank accounts, retirement accounts, and investment portfolios
- Documentation of any business interests you own or have a stake in
- A summary of any significant debts, including student loans, mortgages, or business liabilities
- Any prior marital settlement agreements or divorce decrees if you’ve been married before
- A sense of what financial issues are most important to you going into the marriage
The more complete your financial picture, the more efficient and thorough the drafting process will be.
