Divorce Timeline in Illinois - Frequently Asked Questions
How long does a divorce take in Illinois?
An uncontested divorce in Illinois typically finalizes in about 4 months, while a contested case averages 14 months. Mandatory waiting and separation periods set the floor: even a fully agreed case cannot finalize sooner than the time required to file, serve, and obtain a court date, often 4 to 8 weeks.
What is the waiting period for divorce in Illinois?
Illinois has no statutory waiting period. Timing is driven by court calendar, service of process, and your divorce type. Most uncontested filings still take at least 4 to 8 weeks to finalize.
Why do contested divorces take longer in Illinois?
Contested cases in Illinois add discovery (typically 60 to 180 days), motions and temporary order hearings, settlement conferences, and either trial preparation or trial itself. Each of these adds weeks to months. Disputed custody, business valuations, and forensic accounting are the most common slow-downs.
Can a Illinois divorce be finalized faster than the waiting period?
Illinois does not have a statutory waiting period, so the practical floor is the time required to file, serve, and obtain a court date. Filers with complete agreed paperwork sometimes finalize within 30 to 60 days.
Does Illinois require mediation?
No, Illinois does not require mediation, but courts often encourage it. Many judges will order mediation on contested issues like custody before scheduling a hearing.
