We Handle Every Type of
Prenup & Postnup Situation
A well-written agreement is not about planning for divorce. It is about creating clarity, protecting what matters most, and reducing future conflict. Whether you are entering a marriage, protecting a business, preserving family wealth, or addressing changing circumstances after marriage, we help you create an agreement that is practical, enforceable, and tailored to your goals.
A prenuptial agreement can address property rights, businesses, investments, retirement accounts, future income, inheritances, debt obligations, and potential spousal maintenance. Every agreement is customized based on your specific goals and circumstances.
A prenuptial agreement is signed before marriage, while a postnuptial agreement is signed after marriage. Both can address many of the same financial and property issues, but the timing and circumstances are different.
Generally, yes. Illinois courts enforce properly drafted agreements that meet legal requirements and are entered into voluntarily with full financial disclosure. Careful preparation is critical to maximize enforceability.

Here's How We Handle
Prenup & Postnup Agreements
Most people have never created a marital agreement before. We guide you through the process step-by-step, helping you understand your options, identify potential risks, and create an agreement designed to protect your interests while remaining fair and enforceable.
The First Conversation
Filing & Initial Disclosures

Going to Court (If Needed)
After Signing
We start with a conversation about what you and your future spouse want to address in writing: property each of you brings to the marriage, business interests, expected inheritances, retirement accounts, and how maintenance might work if the marriage ever ends. We review which issues a prenup can enforceably cover under Illinois law and which it cannot. By the end of the consultation, you'll know what the agreement can do for you and what the realistic timeline and cost look like.
For prenups and postnups, the equivalent of filing is initiating full financial disclosure between the parties. Both sides exchange documents covering income, assets, debts, and any prior obligations. Illinois courts require this disclosure to be complete and accurate for the agreement to be enforceable, and we manage the document exchange so nothing falls through.
We draft the agreement based on your conversation and the financial disclosures, then send it to your future spouse's attorney for review. Both sides negotiate any terms that need adjustment. The negotiation often surfaces useful conversations couples haven't had yet, like what happens if one spouse leaves work to raise children. We document the final terms in language that will hold up if the agreement is ever tested.
Prenups and postnups don't go through court at signing. The agreement is only tested in court if it is later challenged, usually during a divorce. We structure the original drafting and signing process so the agreement can withstand challenge, which means clear language, complete disclosure, independent counsel for both parties, and execution well in advance of the wedding.
For prenups, the agreement takes effect on your wedding day. For postnups, it takes effect on signing. We provide you with executed copies, recommendations on where to store them, and guidance on when you might want to revisit the terms, such as after a major asset acquisition, the birth of a child, or significant business changes. Life changes, and the agreement can change with you through amendments.
Here's What You Can Count On
Family law cases run long. The right working relationship matters as much as the right legal strategy. These are the standards we hold ourselves to, every day, from your first call through your final order.
Communication Standard
We respond to every client message within one business day, often the same day. When your attorney is in court, the team responds first so you always know we have heard you.
Who Makes The Decisions
We explain your options in plain English, give you our recommendation, and tell you the tradeoffs. We never settle, file a motion, or commit you to anything without your written authorization.

Billing Transparency
Every invoice is itemized so you see exactly what we did and what it cost. If a strategic choice will add meaningful cost, we tell you before we do the work.
Documentation Rhythm
After every hearing, negotiation, or strategic decision, you get a written summary of what happened, what was decided, and what comes next. You always have a record to re-read when the moment is calmer.

What People Actually Ask Us About Illinois Prenups & Postnups
These are the questions we hear most often from people considering a prenup or postnup in Illinois. If yours is not here, send it over.
A prenup can address property classification (what stays separate, what becomes shared), debt allocation, business interests, inheritance handling, spousal maintenance terms, and how specific assets are valued. It cannot address child custody, child support, or anything that affects a child's welfare, because Illinois courts retain final authority on those issues.
Strongly recommended, and effectively required for enforceability. Illinois courts can refuse to enforce a prenup where one party did not have independent legal counsel, especially if the agreement heavily favors the represented party. We draft prenups for one party and require the other side to engage their own attorney for review.
Technically possible, but risky. Illinois courts can refuse to enforce a prenup signed under time pressure, and a week before the wedding qualifies. We recommend signing at least 30 days before the wedding, and ideally 60 to 90 days, so neither party can later argue they signed under duress.
Prenup costs depend on the complexity of your finances and how much negotiation is required between the parties' attorneys. Simple agreements with limited assets typically run on flat fees; agreements involving businesses, real estate portfolios, or substantial inheritances often run hourly because the negotiation phase varies. We quote the realistic cost range at the first consultation.
Yes, through a postnuptial amendment or a new postnuptial agreement. Couples often update their prenups after major life events: receiving a substantial inheritance, starting or selling a business, or having children. The same enforceability standards apply to modifications as to the original agreement, including full disclosure, voluntary execution, and independent counsel.
There is no good research showing that prenups affect divorce rates. What they do is set clear financial terms in advance, which often makes the financial side of a divorce faster and less contentious when one happens. Many couples report feeling more secure in the marriage knowing the financial framework is already settled.
