Can I Make a Big Purchase During an Illinois Divorce?
Like many legal questions, the honest answer is: it depends, and the details matter. Some states freeze both spouses' finances automatically the moment a divorce is filed. Illinois does not. But that does not mean a mid-divorce car, boat, or house purchase is safe. Illinois protects marital finances in three other ways, and a careless purchase can cost you at the negotiating table.
1. There Is No Automatic Freeze, Unless Someone Asks
Illinois has no automatic freeze on your finances in a divorce. There is an automatic order once you are served: under 750 ILCS 5/501.1, a Dissolution Action Stay takes effect on its own and bars abuse, harassment, and hiding a child of the marriage from the other parent, printed right on the summons. It does not freeze property or accounts anymore. The Illinois Supreme Court struck down that part of the statute in Messenger v. Edgar (1993). Instead, under 750 ILCS 5/501, either spouse can ask the court for a temporary restraining order or injunction barring unusual transfers, sales, or borrowing while the case is pending. If an order like that exists in your case, a big purchase without consent can put you in contempt. Read every order before you spend. (We cover this in detail in our post on automatic restraining orders in Illinois.)
2. Dissipation: The Clawback Rule
Under 750 ILCS 5/503(d)(2), money spent for a purpose unrelated to the marriage while the marriage is breaking down is dissipation, and the court can charge it back against your share of the property division. A luxury purchase that benefits only you, made with marital funds after the breakdown, is a textbook dissipation target. You could keep the car and lose its value twice.
3. The New Asset Is Probably Marital Anyway
Here is the part that surprises people: in Illinois, property acquired up until the judgment of dissolution is generally presumed marital under 750 ILCS 5/503, no matter whose name is on it and no matter that you are separated. That new truck bought mid-case usually lands right back in the pot to be divided, and it complicates valuation along the way.
The Safest Practice
If a major purchase can wait until after the judgment, wait. If it genuinely cannot:
- Disclose it in writing to your spouse and your attorney before you buy
- Get written agreement from your spouse or an order from the court
- Document the source of funds, especially if you believe they are non-marital
- Keep it proportionate. A reliable used car for work reads differently than a sports car.
The Bottom Line
You will not find an automatic rule that says no. What you will find is a judge who sees every dollar. Before making any significant purchase during your divorce or separation, spend ten minutes with your attorney first. It is the cheapest insurance you can buy.

Questions People Ask
Can I buy a car or make a big purchase while my Illinois divorce is pending?
There is no automatic rule against it since Illinois has no automatic freeze on finances. But a big purchase made with marital funds that benefits only you, after the marriage has broken down, can be treated as dissipation under 750 ILCS 5/503(d)(2), letting the court charge that value back against your share of the property division later. If a court order already restricts spending, a purchase without consent can also put you in contempt.
If I buy something new during my divorce, does it become marital property?
Usually yes. Under 750 ILCS 5/503, property acquired up until the judgment of dissolution is generally presumed marital, no matter whose name is on it and even if the spouses are already separated. That means a new purchase made mid-case usually lands right back in the pot to be divided, and it can complicate the valuation of the overall estate.
What should I do before making a major purchase during my Illinois divorce?
If the purchase can wait until after the judgment, wait. If it cannot, disclose it in writing to your spouse and attorney before buying, get written agreement or a court order, document the source of funds especially if you believe they are non-marital, and keep the purchase proportionate. A reliable used car for work reads very differently to a judge than a luxury purchase.
