How Long Does Divorce Take in Illinois? (2026)

Illinois has no mandatory waiting period — meaning your divorce can be finalized as quickly as the courts can process your paperwork and schedule a hearing. In practice, uncontested divorces take 4–8 weeks.

The Short Answer

No Mandatory Waiting Period

Illinois has no statutory waiting period. The 6-month separation period mentioned in Illinois law (750 ILCS 5/401) is a presumption, not a requirement — if you both agree irreconcilable differences exist, you don't need to wait 6 months.

Local rules caveat: Some Illinois judicial circuits have local procedural requirements that may add brief delays — for example, a 30-day rule from the summons return date in some circuits. These are typically waivable in uncontested cases. Check with your county.

Stage-by-Stage Timeline

Stage 1 — Preparation (1–2 weeks)

Use illinoislegalaid.org to generate forms. Gather financial documents. Reach agreement with your spouse.

Stage 2 — Filing (1 day)

File Petition at Circuit Clerk. E-file available statewide.

Stage 3 — Service/Entry of Appearance (1 day–2 weeks)

Cooperative spouse: Files Entry of Appearance immediately — no waiting. Sheriff service: Typically 1–2 weeks. 30-day response window begins.

Stage 4 — Response Period (30 days or waived)

In agreed divorces with immediate Entry of Appearance, this step is effectively skipped.

Stage 5 — Finalize Agreement (1–2 weeks)

Complete Marital Settlement Agreement and Parenting Plan. Both spouses sign.

Stage 6 — File Prove-Up Documents and Schedule Hearing (1–3 weeks)

Submit documents to court. Schedule prove-up hearing. Cook County: longer wait times. Downstate: often within days to a week.

Stage 7 — Prove-Up Hearing (5–15 minutes for uncontested)

Judge signs Judgment of Dissolution.

Stage 8 — File Judgment (1 day)

File signed Judgment with Clerk. Get certified copies.

The Big Difference: Cook County vs. Downstate

Cook County: Illinois's most congested court system. Filing, processing, and hearing scheduling all take longer. Prove-up hearings may be scheduled several weeks out. Consider whether filing in a collar county is an option if you qualify.

Collar counties (DuPage, Lake, Kane, Will, McHenry): Moderately efficient. Typically faster than Cook.

Downstate counties: Often the fastest. Smaller caseloads mean hearings can sometimes be scheduled within days of filing.

What Speeds Up an Illinois Divorce

Spouse files Entry of Appearance immediately — Eliminates any waiting period.

Using illinoislegalaid.org — Accurate, complete forms the first time. Avoid rejections.

Filing in a less-busy county — If both you and your spouse qualify in multiple counties, consider which is less congested.

Having your MSA ready before the hearing — Don't wait until the prove-up to finalize terms.

What Slows Down an Illinois Divorce

Cook County backlogs — The busiest courts in Illinois take significantly longer.

Parenting Plan disputes — Any disagreement on the Parenting Plan must be resolved before the court will enter the Judgment.

Incomplete financial disclosure — Some counties require specific financial disclosures before the prove-up. Missing documents cause delays.

Local rule surprises — Each circuit has its own rules. Not checking local requirements is a common source of delays.
