Illinois Divorce by County: Complete Guide for All 102 Counties

Filing for divorce in Illinois requires you to file in the county where you or your spouse meets the residency requirement.

Last Updated: February 2026

Why County-Specific Information Saves You Money

Avoid Rejected Filings
Each county in Illinois has specific formatting requirements, caption styles, and required forms. Using county-correct documents the first time avoids rejection and refiling fees.

Budget Accurately
Knowing your exact filing fee, service costs, and required class fees lets you budget precisely. No surprises.

Choose the Right Approach
Some counties have excellent self-help centers that make DIY divorce easier. Others have complex e-filing systems where professional help is worth it. County-specific knowledge helps you decide.

Find Free Resources
Many counties offer free mediation for low-income residents, law library access, or pro bono attorney consultations. You won't know about these unless you check your county's specific resources.

Professional Help with Your Illinois Divorce

Whether you choose to work with an attorney or use an online divorce service, professional assistance can help you navigate your county's specific requirements and avoid costly mistakes. Online divorce services provide affordable alternatives to traditional attorneys for uncontested cases, with county-specific forms and filing assistance.

Illinois Divorce Requirements (Statewide)

While county procedures differ, these requirements apply across all 102 Illinois counties:

Residency: 90 days before filing.

Grounds: Illinois allows no-fault divorce, meaning you don't need to prove wrongdoing to end your marriage.

Waiting Period: 6 months for irreconcilable differences after filing.

Property Division: Illinois follows equitable distribution rules, meaning property is divided fairly based on various factors (not necessarily equally).

Child Custody: Illinois courts focus on the child's best interests when determining custody and parenting time.

Common Questions About Illinois County Divorce Filings

Which county should I file in?

You must file in the county where either you or your spouse meets the residency requirement. In Illinois, you need 90 days residency before filing. If you both live in Illinois but in different counties, you can typically choose to file in either county.

Can I file in a different county to save on filing fees?

No. You must meet the residency requirement for the county where you file. You cannot simply choose the cheapest county. However, if you're planning to move and haven't filed yet, establishing residency in a county with lower fees could save you money.

Do I need to appear in court in person?

Many Illinois counties now allow some hearings to be conducted remotely via Zoom or phone, especially for uncontested divorces. However, policies vary by county and judge. Check your specific county's rules or ask the clerk's office.

What if my spouse lives in another state?

You can still file for divorce in Illinois as long as you meet the residency requirement of 90 days. You'll need to serve your spouse according to Illinois's rules for out-of-state service.
