How long an Illinois divorce takes, stage by stage

Illinois has no waiting period. No cooling-off month, no mandatory separation before filing, nothing between you and a judgment except the work. So the range comes from the court itself: its instruction packet says the divorce process may take between six months and two years and often involves multiple court visits.

The spread between those two numbers is almost entirely about children and money, in that order.

How long does an uncontested divorce take in Illinois?

Two to four months in most counties, and the constraints are administrative rather than legal.

You file. Your spouse either gets served or signs an Appearance, which is faster. Your spouse has 30 days to respond. You write and sign a marital settlement agreement, and if there are children, a parenting plan. Then you call the clerk for a prove-up date, and the length of that wait is entirely about your judge's calendar.

The one legal constraint on the short end is the six month separation presumption. If you have been apart six months by the day of the prove-up, grounds are automatic. If not, you testify about the breakdown, which adds about a minute to the hearing and nothing to the calendar.

How long does a contested divorce take in Illinois?

A year to two years, and the drivers are predictable.

• Discovery on a business or a self-employed spouse. Interrogatories, document production, subpoenas to banks and a valuation expert on each side is a six to nine month sequence on its own.

• A contested parenting case. Mediation, a guardian ad litem or child representative, and possibly a custody evaluation each carry their own scheduling delay.

• A dissipation claim. These require a notice with dates and identified property, and the accounting behind it takes real work.

• A judge's trial calendar. In the busier collar counties a multi-day trial date can be months out from the day everyone is ready.

What deadlines actually control an Illinois divorce?

These are the ones written into the statutes and the Supreme Court Rules. Everything else moves around them.

• 30 days to serve the summons. Rule 102(b) says a summons requiring appearance within 30 days may not be served later than 30 days after its date. If it goes stale, the clerk issues an alias summons and you try again.

• 30 days to appear or answer. Under Rule 101(d), the summons requires the respondent to file an appearance or answer within 30 days after service, not counting the day of service.

• 21 days to respond to temporary relief. A response to a motion for temporary maintenance, temporary support or an injunction is due 21 days after service of the notice of motion, or at the time the temporary restraining order specifies.

• 90 days to the initial case management conference. In a case with children, Rule 923(a) requires an initial conference not later than 90 days after service is obtained.

• 120 days to file a parenting plan. Every parent files a proposed plan, jointly or separately, within 120 days after service or filing of any petition for allocation of parental responsibilities.

• 60 days after the case management conference for the parenting class. Rule 924 requires every party to complete an approved parenting education program of at least four hours in that window.

• 30 days after mediation for the full case management conference. That is where the court decides whether to appoint an attorney for the child, a guardian ad litem or a child representative.

• 60 days before trial for a dissipation notice. Or 30 days after discovery closes, whichever is later.

• 60 days after proofs close for the judgment. Section 413(a) gives the judge 60 days from the closing of proofs to enter judgment, extendable to 90 by an order specifying good cause.

What happens at each stage of an Illinois divorce?

Weeks 1 to 2: filing and service. You file a verified petition and a Certificate of Dissolution with the circuit clerk, e-filing through eFileIL unless you qualify for an exemption. The summons goes to the sheriff, or your spouse signs an Appearance and skips the whole step.

Weeks 2 to 8: the response and any emergency motions. Your spouse appears or answers within 30 days. If money needs to be locked down or one household needs supporting, this is when a petition for temporary relief gets filed, and it is the moment a financial affidavit becomes mandatory rather than optional.

Months 2 to 4: the first conferences. In a case with children, the initial case management conference happens by day 90 from service, parenting education gets scheduled, and mediation gets ordered if there is no agreed plan. In a case without children, this period is usually quiet unless somebody is pushing discovery.

Months 3 to 9: discovery. Interrogatories capped at 30 including subparts, document requests, depositions, subpoenas to banks and employers, and expert appraisals of any business or real estate.

Months 6 to 12: settlement, or a pretrial. Most Illinois divorces resolve here. The mediation chapter covers how the settlement conference and the pretrial actually work.

Months 9 to 24: trial. Bifurcated, with grounds tried first and the money and children after. Then 60 days for the judgment.

What makes an Illinois divorce take longer than it should?

• Waiting to gather financial records until someone demands them. Illinois does not require an early disclosure in every case, which means nobody forces you to start. Pulling four years of statements across six accounts under a two week deadline is where cases stall.

• Filing before you know what you own. A petition is easy to file and a classification argument is expensive to lose. Sorting marital from non-marital early shortens everything downstream.

• Missing the parenting plan deadline. If nobody files a plan, section 602.10(b) makes the court hold an evidentiary hearing to allocate responsibilities, which is a trial nobody wanted.

• Treating the parenting class as optional. The court may impose sanctions on a party who willfully fails to complete it, and it will not finalize a case around it.

Can you speed up an Illinois divorce?

Three ways, and one of them is a different track entirely.

If you have no children, were married eight years or less, own no real estate and have modest income and property, joint simplified dissolution collapses the whole process into one joint petition and one hearing. The eligibility rules are strict, but nothing else in Illinois is faster.

Short of that, get your spouse to sign an Appearance instead of being served, which removes the sheriff and the 30 day service window from your calendar. And write the settlement agreement before the first court date rather than after it, because a signed agreement turns your next appearance into a prove-up.
