How Long Does a Post-Conviction Case Take in Illinois?

It's one of the first questions clients and family members ask, and it deserves a straight answer: a typical Illinois post-conviction case takes one to three years in the circuit court. If the petition is dismissed and appealed, the full process often runs three to five years or longer. Some cases resolve faster. Cases that reach an evidentiary hearing, involve new forensic testing, or travel up and down the appellate courts can take considerably more.

That range frustrates people, understandably. But the timeline isn't arbitrary. It flows directly from how the Illinois Post-Conviction Hearing Act, 725 ILCS 5/122-1 et seq., structures these cases. Once you understand the three stages, you can see where the time goes, and what you can do about it.

First, Don't Confuse the Deadline With the Duration

Two different clocks matter in post-conviction work, and people mix them up constantly.

The first clock is the filing deadline: how long you have to start the case. Under 725 ILCS 5/122-1(c), the limits are strict. If no direct appeal was filed, the petition is generally due within three years of the date of conviction. If a direct appeal was taken, the deadline is tied to the conclusion of those proceedings, generally six months from the deadline for seeking certiorari in the United States Supreme Court. Claims of actual innocence are exempt from these limits, and a late petition may still proceed if the delay was not due to the petitioner's culpable negligence. Those are exceptions, not the plan.

The second clock is the duration: how long the case takes once filed. That's what the rest of this article covers. The practical point: the filing deadline is short and unforgiving, while the case itself is long. Waiting to "see how things go" burns the one clock you can't get back.

Stage One: The 90-Day Review

Illinois post-conviction petitions proceed in three stages, and only the first one has a firm statutory clock.

Within 90 days of the petition's filing and docketing, the circuit court must independently examine it. 725 ILCS 5/122-2.1(a). At this stage, no prosecutor is involved and no hearing is held. The judge reads the petition alone and asks one question: is it frivolous or patently without merit? If so, the court summarily dismisses it. If not, or if the court simply fails to rule within the 90 days, the petition advances to the second stage. The Illinois Supreme Court has held that the 90-day requirement is mandatory: a summary dismissal entered after the deadline is void, and the petition moves forward. People v. Swamynathan, 236 Ill. 2d 103 (2010).

The standard at stage one is low: the petition need only state the "gist" of a constitutional claim. But low is not zero. A substantial share of pro se petitions are dismissed at this stage, which is why the drafting matters even at the "easy" stage. In the best case, you'll know within three months whether the case has survived its first test.

Stage Two: Where Most of the Time Goes

If the petition survives, it is docketed for second-stage proceedings, and here the statutory clock disappears. In practice, stage two commonly takes six months to two years, and it's the phase clients find hardest, because much of the waiting is invisible.

Several things happen at this stage. The court appoints counsel for indigent petitioners, 725 ILCS 5/122-4, and counsel must comply with Supreme Court Rule 651(c): consulting with the petitioner, examining the record, and amending the petition as needed. Amending a pro se petition into its strongest form takes real time: obtaining transcripts, tracking down witnesses, securing affidavits. The State then answers or, far more often, moves to dismiss. 725 ILCS 5/122-5. Briefing and argument follow, then a ruling, all on a court calendar shared with hundreds of other cases, and Cook County dockets move differently than downstate ones.

The legal question at stage two is whether the petition makes a substantial showing of a constitutional violation. If it does, the case advances. If not, it's dismissed, and the fight moves to the appellate court.

Stage Three: The Evidentiary Hearing

A petition that makes a substantial showing earns a third-stage evidentiary hearing: the first point in the entire process where a court hears live testimony. Witnesses testify, evidence is admitted, and the judge resolves the factual disputes at the heart of the claim, such as what trial counsel did or didn't do, or what a newly discovered witness actually saw.

Scheduling the hearing typically adds several months to a year, particularly when the case requires transporting an incarcerated petitioner, coordinating expert witnesses, or litigating discovery. After the hearing, the court may take the matter under advisement before ruling. Third-stage relief, a new trial or a new sentencing hearing, is the goal of the whole endeavor, and cases that get this far deserve the preparation time.

If the Petition Is Denied: The Appeal

A dismissal at any stage can be appealed, and the appeal adds its own timeline. The notice of appeal is due within 30 days. From there, preparing the record, briefing by both sides, and awaiting a decision from the Illinois Appellate Court typically takes a year to two years. If the appellate court reverses, holding, for example, that the petition should have advanced to the next stage, the case returns to the circuit court and the process resumes where it left off. This is how post-conviction cases stretch to five years and beyond: not because any single step is endless, but because the steps compound.

What Actually Affects the Timeline

Some factors are outside anyone's control: the county's docket, the assigned judge, the State's response time. But several are not:

A well-drafted initial petition avoids summary dismissal and gives appointed or retained counsel a foundation instead of a rescue project.

Complete supporting evidence, the affidavits, records, and exhibits the Act requires under 725 ILCS 5/122-2, prevents months of delay gathering what should have been attached at filing.

Retained counsel from the outset eliminates the wait for appointment and the gap while new counsel learns the record.

Prompt, focused responses to the State's motion to dismiss keep the case from sitting on a status call.

The Bottom Line

Plan for one to three years in the circuit court, and three to five years if the case is appealed. Every stage has a purpose, and the single most important thing you control is the beginning: filing on time, with a petition strong enough to survive stage one and built to win at stages two and three.
