How Illinois Calculates It
Illinois divides marital property using equitable distribution under 750 ILCS 5/503, meaning courts divide assets fairly — not necessarily 50/50. Illinois courts consider 12 statutory factors including each spouse's contribution, marriage duration, economic circumstances, and tax consequences when determining a just division of the marital estate. Under Section 503(a), marital property includes all assets and debts acquired by either spouse after the marriage date and before the dissolution judgment — regardless of whose name appears on the title. Illinois courts recognize homemaker contributions as equal to financial contributions under 750 ILCS 5/503(d)(1).
Non-marital property includes assets owned before marriage, inheritances, and gifts, but commingling non-marital funds with marital accounts can convert them to marital property. Illinois takes dissipation claims seriously under 750 ILCS 5/503(d)(2). The claiming spouse must establish a specific date when the irretrievable breakdown of the marriage began — spending marital funds for non-marital purposes after that date may require reimbursement. With approximately 19,000 divorce filings annually and a divorce rate of 1.5 per 1,000 population, Illinois courts handle significant property division caseloads.
Median contested divorce costs reach $12,500, while uncontested cases average $3,000, with attorneys charging a median rate of $350 per hour. Retirement accounts in Illinois require special handling. Private-sector 401(k)s and pensions are divided through a Qualified Domestic Relations Order (QDRO), while state government pensions use a Qualified Illinois Domestic Relations Order (QILDRO) under 40 ILCS 5/1-119. Both vested and non-vested pension benefits are considered marital property under 750 ILCS 5/503(b).
IRAs do not require a QDRO — funds transfer directly between accounts without tax penalties when ordered by a divorce judgment.

Frequently Asked Questions
How is property divided in an Illinois divorce?
Illinois uses equitable distribution under 750 ILCS 5/503, dividing marital property fairly but not necessarily equally. Courts evaluate 12 statutory factors including each spouse's contributions, marriage length, economic circumstances, and tax consequences under Section 503(d). Homemaker contributions carry equal weight to financial contributions. Typical splits range from 50/50 to 60/40 depending on circumstances.
What is considered marital property in Illinois?
Under 750 ILCS 5/503(a), marital property includes all assets and debts acquired by either spouse after the marriage and before the dissolution judgment — regardless of title ownership. This covers income, real estate, vehicles, retirement contributions, and business interests. Non-marital property includes pre-marriage assets, inheritances, and gifts, but commingling these with marital funds can convert them to divisible marital property.
Is Illinois a community property or equitable distribution state?
Illinois is an equitable distribution state, not a community property state. Unlike the 9 community property states that mandate a 50/50 split, Illinois courts under 750 ILCS 5/503(d) divide marital assets based on fairness using 12 statutory factors. This means one spouse may receive 60% or more of marital assets if factors such as earning capacity, health, or custodial responsibilities justify an unequal division.
How are retirement accounts divided in an Illinois divorce?
Both vested and non-vested retirement benefits are marital property under 750 ILCS 5/503(b). Private-sector 401(k)s and pensions require a Qualified Domestic Relations Order (QDRO) for division, while Illinois state government pensions use a Qualified Illinois Domestic Relations Order (QILDRO) under 40 ILCS 5/1-119. IRAs transfer directly between spousal accounts without a QDRO and incur no tax penalties when ordered by a dissolution judgment.
What happens to the house in an Illinois divorce?
Illinois courts typically handle the marital home in one of three ways: one spouse buys out the other's equity share, the home is sold and proceeds divided equitably, or the court orders a sale under 750 ILCS 5/503. Courts prioritize keeping children in the family home when financially feasible, per Section 503(d)(3). A home purchased before marriage may remain non-marital property unless marital funds were used for mortgage payments or renovations.
Can I keep my inheritance in an Illinois divorce?
Inheritances are classified as non-marital property under 750 ILCS 5/503(a)(1) and are generally not subject to division. However, if you deposit inherited funds into a joint account or use them to improve marital property, courts may reclassify them as marital through commingling. To protect an inheritance, keep it in a separate account titled solely in your name and avoid mixing it with marital funds.
How is debt divided in an Illinois divorce?
Illinois courts divide marital debts equitably under the same 750 ILCS 5/503(d) factors used for assets. Debts incurred during the marriage for family purposes — mortgages, credit cards, medical bills — are typically marital obligations regardless of whose name is on the account. Debts incurred after the irretrievable breakdown date may be assigned solely to the spouse who incurred them, particularly if they constitute dissipation under Section 503(d)(2).
What factors do Illinois courts consider in property division?
Under 750 ILCS 5/503(d), Illinois courts weigh 12 factors: each spouse's contribution to acquiring marital property, homemaker contributions, dissipation of assets, property value assigned to each party, marriage duration, economic circumstances, prenuptial agreements, age and health of both spouses, custodial provisions, whether division is in lieu of or in addition to spousal maintenance, reasonable opportunity for future asset acquisition, and tax consequences of the division.
