Residency Requirements for Divorce in Illinois
Before filing for divorce, at least one spouse must meet the residency requirement:
- You or your spouse must have lived in Illinois for at least 90 days before filing.
- If you have children, they must have lived in Illinois for at least six months for the court to have jurisdiction over custody matters. (750 ILCS 5/401)
Grounds for Divorce in Illinois
Illinois is a no-fault divorce state, meaning you do not need to prove wrongdoing by your spouse. The only recognized ground for divorce is “irreconcilable differences,” which means:
- The marriage has broken down beyond repair.
- Efforts at reconciliation have failed or would be impractical.
- If both spouses agree to the divorce, there is no mandatory separation period.
- If one spouse objects, the court may require a six-month separation before finalizing the divorce. (750 ILCS 5/401)
Division of Marital Property
Illinois follows equitable distribution, meaning assets are divided fairly, though not equally. Courts consider factors such as:
- The duration of the marriage.
- Each spouse’s financial and non-financial contributions.
- The economic circumstances of each party.
- Child custody arrangements.
Marital property includes assets acquired during the marriage, such as homes, bank accounts, and retirement benefits. Non-marital property (e.g., inheritances or pre-marriage assets) typically remains with the original owner. (750 ILCS 5/503)
Alimony (Spousal Maintenance) in Illinois
Spousal maintenance, commonly known as alimony, is awarded based on:
- Each spouse’s income and financial needs.
- The standard of living is established during the marriage.
- The duration of the marriage.
- Contributions of each spouse (financial and non-financial).
Illinois uses a formula to determine maintenance payments for couples with a combined gross income below $500,000. Courts may deviate from the formula for higher-income couples. (750 ILCS 5/504)
Child Custody and Parenting Time
Illinois law defines child custody as “allocating parental responsibilities” and “parenting time.”
- Courts prioritize the best interests of the child, considering factors such as:
- Each parent’s relationship with the child.
- The child’s adjustment to home, school, and community.
- Any history of domestic violence or substance abuse.
Parenting time is usually shared, but courts may grant sole parental responsibility if it is in the child’s best interest. (750 ILCS 5/602.7)

Child Support Guidelines
Child support in Illinois is determined using the income shares model, which considers:
- The combined income of both parents.
- The number of children.
- Each parent’s respective parenting time.
The Illinois Department of Healthcare and Family Services provides an online child support estimator for calculating estimated payments. (Illinois Child Support Estimator)
How Long Does a Divorce Take in Illinois?
The length of a divorce case varies based on:
- Whether both parties agree on the terms (uncontested) or have disputes (contested).
- The complexity of property division and child custody arrangements.
- The court’s schedule.
Average timelines:
- Uncontested Divorce: Typically finalized in 2-6 months.
- Contested Divorce: Depending on litigation, this can take 12 months or longer.

- Protect your financial interests.

Consulting an attorney is highly recommended if you have significant assets, children, or disputes with your spouse.
