When two people decide to build a life together, it’s natural to focus on the future with hope and excitement. But while love and trust are key parts of any marriage, planning for life’s uncertainties is just as important. This is where prenuptial and postnuptial agreements come in.
Whether signed before the wedding or after the vows are exchanged, these legal documents help define how assets, debts, and other financial matters will be handled during the marriage and in case it ends in separation, divorce, or death.
Understanding These Legal Agreements
Prenuptial agreements are contracts that couples sign before getting married. Postnuptial agreements are similar contracts, but they’re signed after the marriage has already taken place. Both are used to set clear terms around the ownership and control of personal and joint assets.
These agreements are not just for high-net-worth individuals. Many couples—regardless of income—choose to use them to bring structure and clarity to their financial life together. By making these choices ahead of time, couples may avoid confusion and costly disputes later on.
What Should Be Included in the Agreement?
Each couple’s agreement should be customized to fit their unique situation, but some common provisions include:
- Protection of Individual Property
Assets owned by each person before marriage can be clearly marked as separate property. - Handling of Debt
The agreement can ensure one spouse isn’t responsible for the other’s debt. - Spousal Support Terms
Also known as maintenance or alimony, the agreement can include whether either party will be entitled to support after a divorce. - Rules About Shared Property
It can set terms for how jointly acquired property will be divided, helping avoid arguments later. - Financial Responsibilities During the Marriage
This may include who will manage bank accounts, how bills are paid, and how savings are handled.
These elements can bring peace of mind and help both parties understand their financial roles clearly.
When Is the Right Time to Consider One?
There’s no one-size-fits-all answer, but here are some situations where a prenuptial or postnuptial agreement might be worth considering:
- You Own Property or a Business
If you want to protect your interest in a home or business, it can be spelled out in the agreement. - You Have Children from a Previous Relationship
An agreement can help ensure assets are passed down according to your wishes. - There Is a Big Difference in Income or Debt
When one partner earns much more or owes significantly more, these documents can provide balance. - You Expect an Inheritance
If a large sum is expected in the future, you can protect it with an agreement. - You Simply Want Financial Clarity
Some couples find that laying out financial terms creates better communication and fewer surprises.
How Illinois Courts Treat These Agreements
In Illinois, prenuptial and postnuptial agreements are recognized and enforceable—if done correctly. The courts look for signs that:
- Both parties fully disclosed their financial situation before signing
- There was no pressure or coercion involved
- Each person had time to review and understand the agreement
- The terms are fair and not heavily one-sided
Hiring a qualified attorney can help ensure the document meets all legal standards and protects your interests.
Can These Agreements Be Challenged?
Yes, under certain circumstances, prenuptial and postnuptial agreements can be contested in court. A judge may rule an agreement invalid if:
- One spouse was not truthful about their finances
- The agreement was signed under pressure or without time to consider
- The terms are extremely unfair or would cause severe hardship
- The agreement was not put in writing and signed properly
This is why it’s important to work with a family law attorney who understands the legal requirements and will help you draft a strong, enforceable agreement.

Frequently Asked Questions
- What’s the main difference between a prenuptial and postnuptial agreement?
A prenuptial agreement is signed before marriage, while a postnuptial agreement is signed after the couple is already married. Both serve similar purposes in outlining how assets, debts, and financial matters will be handled. - Do I need a lawyer to create a prenup or postnup in Illinois?
Yes, it’s strongly recommended. A lawyer ensures the document meets Illinois legal standards and that your rights are fully protected. Having separate attorneys for each spouse is often advised to avoid conflicts of interest. - Can a prenup or postnup include child custody or support terms?
No, Illinois law does not allow these agreements to decide child custody or support. Courts determine those matters based on the child’s best interests at the time of divorce or separation. - Are these agreements only for wealthy couples?
Not at all. Many couples of all income levels use prenuptial and postnuptial agreements to clarify financial responsibilities, protect personal property, and avoid future disputes. - How long does it take to draft a prenuptial or postnuptial agreement?
The timeline can vary depending on the complexity of your finances and how quickly both parties can agree on the terms. In general, it’s best to start the process well in advance—especially before a wedding date.
