How Long Does a Contested Divorce Take in Illinois?
A contested divorce in Illinois can take several months to more than a year, depending on what the spouses disagree about and how quickly the case moves through the court system. Disputes over property, parenting time, child support, or spousal maintenance can add significant time. Illinois law also includes a six-month separation provision related to proving irreconcilable differences, but that is not necessarily a six-month waiting period before a spouse can file. Knowing what affects the schedule can help people plan and avoid delays.

Typical Timeline for a Contested Divorce in Illinois
There is no single statewide deadline for finishing a contested divorce in Illinois. A relatively straightforward case with limited disputes may be resolved in several months. A case involving extensive financial discovery, contested parenting arrangements, expert evaluations, or a trial may take a year or longer. These are general estimates, not guarantees or official statewide averages.
The length depends on both the case and the court’s schedule. Parties may need time to exchange financial information, negotiate, attend mediation, and prepare for hearings. Even after the spouses agree on the major issues, preparing and submitting the final paperwork can take additional time.
| Case situation | General planning range | Common factors |
|---|---|---|
| Limited disputes, agreement reached early | Several months | Prompt financial disclosure, few contested issues, available court dates |
| Multiple unresolved issues | Often several months to a year or more | Negotiation, mediation, discovery, temporary orders |
| Trial or complex financial or parenting dispute | A year or longer is possible | Expert analysis, court calendars, motions, trial preparation |
These ranges describe possible planning horizons, not legal deadlines. A case can take longer if a spouse avoids service, fails to provide documents, changes attorneys, or asks the court to resolve repeated disagreements.
What Makes an Illinois Divorce Contested?
A divorce is contested when the spouses have not resolved one or more important issues. They may agree that the marriage should end but disagree about how to divide property, allocate debts, arrange parenting time, make major decisions for a child, calculate child support, or determine spousal maintenance. A single unresolved issue can keep a case contested.
“Contested” does not necessarily mean that the spouses will go to trial. They can reach a settlement through negotiation, attorney discussions, mediation, or a settlement conference. If they resolve all issues, the divorce may proceed as an agreed or uncontested matter for final approval, even if the case began with disputes.
Illinois Filing Requirements and the Six-Month Rule
Under the Illinois Marriage and Dissolution of Marriage Act, a spouse generally must meet a residency requirement before filing for dissolution. At least one spouse must have lived in Illinois for 90 days before the case begins, or meet the applicable military-service residency rule. The case is generally filed in the appropriate Illinois circuit court, and local venue rules may also matter.
Illinois does not require spouses to wait six months before they can file for divorce. The six-month rule concerns the legal ground of irreconcilable differences. Under 750 ILCS 5/401(a), a continuous period of living separate and apart for at least six months immediately before the judgment creates an irrebuttable presumption that irreconcilable differences have caused the irretrievable breakdown of the marriage.
The statute also allows the court, in the circumstances described by the law, to waive the six-month period by finding that it is not necessary to prove irreconcilable differences. The details can depend on the case and the current law. A spouse should not assume that the rule always adds six months to the case, or that it can always be waived. An Illinois family-law attorney can explain how it applies to particular facts.
Because the statutory period is measured in relation to entry of the judgment, it can overlap with negotiations and court proceedings. It is not automatically a separate delay that begins only after filing. The six-month provision also does not resolve disputes over finances or children; those matters can continue to affect the timeline.
Stages That Affect the Divorce Timeline
Filing and serving the divorce papers
The case typically begins when one spouse files a petition for dissolution of marriage. The other spouse must receive formal notice, commonly through service of process or an accepted alternative. If the other spouse is difficult to locate or service is challenged, the case may be delayed. Filing does not itself mean the divorce is final or that the disputed issues have been decided.
Temporary orders and early case management
While the case is pending, either spouse may ask the court for temporary arrangements. Depending on the circumstances, these can address parenting time, child support, temporary spousal maintenance, use of a home, or payment of certain expenses. Courts may also set deadlines, schedule status hearings, or direct the parties to complete required steps. Temporary orders can stabilize matters but do not necessarily determine the final outcome.
Financial disclosure and discovery
Each spouse may need to exchange information about income, expenses, assets, and debts. If financial records are incomplete or disputed, formal discovery can include document requests, written questions, or depositions. Business ownership, retirement accounts, real estate, stock compensation, and claims that property is nonmarital may require additional records or expert review.
Discovery often takes longer when a party responds late, records are difficult to obtain, or the value and ownership of assets are disputed. Complete and organized financial disclosures can help both sides assess settlement options and reduce avoidable requests for additional information.
Negotiation and mediation
Many contested divorce cases settle without a trial. The spouses or their attorneys may negotiate a comprehensive agreement or resolve issues one at a time. Mediation can give parties a structured setting to work through disagreements, particularly about parenting plans or financial terms. Depending on the issue and local court practice, mediation may be ordered or encouraged.
Settlement can shorten the process, but it is not guaranteed to do so. Mediation may require multiple sessions, and an agreement still needs to be documented and submitted for the court’s consideration. If only some issues are resolved, the remaining disputes can continue toward hearings or trial.
Pretrial hearings and trial
If the spouses cannot settle, the judge may hold additional hearings and set a trial. The time required to obtain a trial date varies by county, case complexity, and court availability. Preparing for trial can involve organizing exhibits, preparing witnesses, hiring experts, and narrowing the disputed questions.
A trial may take one or more days, but the case does not necessarily end when testimony concludes. The judge may issue a decision from the bench or take the matter under advisement. The parties or attorneys may then need to prepare a written judgment and related documents for the judge’s approval.
Issues That Commonly Lengthen a Contested Divorce
- Parenting disputes: Disagreements about parental responsibilities, parenting time, relocation, or a child’s needs may require additional evidence, mediation, or a court-appointed evaluation.
- Complex property: Businesses, investments, real estate, pensions, and retirement accounts can require valuation or specialized financial analysis.
- Disputed income: Unclear compensation, self-employment income, bonuses, or claims of hidden income can complicate child support and maintenance calculations.
- Nonmarital property claims: The court may need evidence about whether an asset or debt belongs to one spouse individually or is part of the marital estate.
- High conflict or poor cooperation: Repeated motions, missed deadlines, incomplete disclosures, or difficulty communicating can increase both the time and cost of a case.
- Court availability: Scheduling depends partly on the county’s docket and the judge’s calendar.
Not every disagreement creates the same delay. A focused dispute that can be resolved through a short hearing may move faster than a financial or parenting dispute requiring extensive evidence. The number of issues, the quality of the available records, and the parties’ willingness to participate all matter.
How to Help Keep an Illinois Divorce on Track
No spouse can control every part of a court schedule, but practical steps can reduce avoidable delays:
- Gather tax returns, pay stubs, bank statements, debt records, property documents, and retirement-account statements early.
- Respond to formal requests and court deadlines promptly, and keep copies of submitted documents.
- Provide accurate, complete information about income, expenses, assets, and debts.
- Use negotiation or mediation when it is safe and appropriate, and identify which issues are genuinely unresolved.
- Follow temporary court orders and ask a lawyer about a court-approved change rather than ignoring an order.
- Consider whether an expert is needed to value a business, pension, real estate, or other complex asset.
Efficiency should not come at the expense of a sound agreement. Rushing through property division, support calculations, or parenting arrangements may create problems that are difficult to correct after the judgment is entered. The goal is to resolve disputes carefully while avoiding unnecessary procedural conflict.
Can a Contested Divorce Become Uncontested?
Yes. A divorce can begin with disagreements and later settle. If the spouses reach an agreement on all required issues, they can submit the relevant settlement documents for court review. This can avoid a contested trial and may shorten the remaining timeline, although the court still needs to review and enter the final judgment.
Agreements involving children must address the issues required by Illinois law and remain subject to the court’s review. The judge must approve the final judgment and parenting arrangements under the applicable legal standards. A private agreement alone does not end the marriage; the divorce becomes final when the court enters the judgment for dissolution of marriage.
When to Get Case-Specific Advice
An estimated timeline should account for the county where the case is filed, the issues in dispute, and any immediate needs involving children, housing, or finances. Legal advice is especially important when a spouse owns a business, has substantial retirement assets, is considering relocation with a child, or believes that income or property has not been fully disclosed.
For a reliable estimate, an Illinois family-law attorney can review the facts, explain local procedures, identify deadlines, and discuss possible settlement or trial paths. The court’s schedule and the parties’ decisions can change the timeline, so no general article can predict an exact completion date.
