Illinois Property Division
How property is divided in a Illinois divorce. Understand equitable distribution rules, what counts as marital vs. separate property, and how to protect your assets. Updated for 2026.
Illinois follows equitable distribution under 750 ILCS 5/503. Property is divided into 'just proportions' -- fairly but not necessarily equally. The court divides marital property considering all relevant factors. Non-marital property (acquired before marriage, by gift, or inheritance) is assigned to the owning spouse. Marital misconduct may NOT be considered in property division.
What Equitable Distribution Means for You
In an equitable distribution state like Illinois, the court aims to divide property fairly based on each couple's unique circumstances. "Fair" does not necessarily mean "equal." The court considers multiple factors.
Marital Property (Subject to Division)
- • Income earned during marriage
- • Real estate purchased during marriage
- • Retirement contributions during marriage
- • Vehicles purchased during marriage
- • Business income/growth during marriage
- • Marital debts
Separate Property (Usually Not Divided)
- • Property owned before marriage
- • Gifts received by one spouse
- • Inheritances
- • Personal injury settlements
- • Property defined as separate in a prenup

Factors Illinois Courts Consider
When dividing property, Illinois courts consider the following factors:
Each party's contribution to the acquisition, preservation, or increase/decrease in value of the marital or non-marital property, including contribution as a homemaker (503(d)(1))
Any dissipation of marital property by either spouse (503(d)(2))
The value of the property assigned to each spouse (503(d)(3))
The duration of the marriage (503(d)(4))
The relevant economic circumstances of each spouse at the time the division of property is to become effective (503(d)(5))
Any obligations and rights arising from a prior marriage of either party (503(d)(6))
Any antenuptial agreement of the parties (503(d)(7))
The age, health, station, occupation, amount and sources of income, vocational skills, employability, estate, liabilities, and needs of each party (503(d)(8))
The custodial provisions for any children (503(d)(9))
Whether the apportionment is in lieu of or in addition to maintenance (503(d)(10))
The reasonable opportunity of each spouse for future acquisition of capital assets and income (503(d)(11))
The tax consequences of the property division upon the respective economic circumstances of the parties (503(d)(12))
Common Assets Divided in Illinois Divorce
Real Estate
The marital home is often the largest asset. Options include selling and splitting proceeds, one spouse buying out the other, or deferred sale (especially when minor children are involved).
Retirement Accounts
401(k)s, IRAs, and pensions earned during marriage are marital property. Division requires a QDRO (Qualified Domestic Relations Order) to avoid tax penalties. Cost: $500-$1,500.
Business Interests
If either spouse owns a business started or grown during the marriage, its value (or the marital portion of its value) is subject to division. A formal business valuation may be needed.
Vehicles
Cars, boats, and other vehicles purchased during marriage are divided based on current value minus any outstanding loan balance.
Bank Accounts & Investments
Joint and individual accounts funded during the marriage are typically marital property. This includes savings, checking, brokerage, and crypto accounts.

How to Protect Your Assets in Illinois Divorce
Document everything. Create a comprehensive inventory of all assets and debts with current values and documentation.
Keep separate property separate. Do not commingle inherited funds or pre-marital assets with joint accounts.
Monitor joint accounts. Watch for unusual withdrawals or transfers. Courts look unfavorably on dissipation of marital assets.
Get professional valuations. For high-value assets (real estate, businesses, art), professional appraisals ensure accurate division.
Consider tax implications. Some assets have hidden tax costs (e.g., capital gains on stocks). A $100,000 investment account is not the same as $100,000 in cash.
