When you and your spouse cannot agree on one or more significant issues in your divorce, Illinois courts classify your case as contested. This does not mean your divorce will necessarily go to trial or become a prolonged legal battle. It simply means the court must resolve the disagreements you cannot work out on your own. Understanding what contested divorce means—and what the process actually involves—can help you prepare for what lies ahead.
What Makes a Divorce Contested in Illinois?
A contested divorce occurs when spouses disagree about how to resolve one or more issues that must be addressed before the marriage can be dissolved. These disagreements require the court’s involvement to reach a resolution.
The Legal Definition of a Contested Divorce
Illinois law requires courts to address several matters before entering a divorce judgment: allocation of parental responsibilities (if children are involved), child support, spousal maintenance, and property distribution. Under 750 ILCS 5/401, courts cannot finalize a dissolution until these issues are resolved. When spouses cannot reach agreement on any of these matters, the divorce becomes contested.
The term “contested” refers solely to whether the parties agree—not to whether either spouse is at fault. Illinois is a purely no-fault divorce state, meaning the only legal ground for dissolution is that irreconcilable differences have caused the irretrievable breakdown of the marriage. Fault-based grounds were eliminated effective January 1, 2016. Whether your divorce is contested or uncontested, the court will not assign blame or consider marital misconduct when making decisions.
How Contested Differs from Uncontested Divorce
In an uncontested divorce, both spouses agree on all issues and present a complete settlement to the court for approval. The process is typically faster and less expensive because there is no need for extensive discovery, negotiation, or trial preparation.
A contested divorce, by contrast, requires the court to intervene and make decisions the spouses cannot make together. This involvement adds procedural steps and extends the timeline. However, “contested” does not mean “hostile.” Many contested divorces involve reasonable people who simply see certain issues differently and need a structured process to reach resolution.
When Disagreement Creates Contested Status
Your divorce becomes contested as soon as you and your spouse disagree about any issue the court must resolve. This can happen at the outset—one spouse files a petition proposing certain terms, and the other spouse files an answer disagreeing—or it can develop during negotiations when settlement talks break down on a particular issue.
Even a single unresolved dispute can make an otherwise straightforward divorce contested. For example, two spouses might agree on property division, child support, and parenting arrangements but disagree about maintenance. That single issue makes the case contested.
What Issues Can Create a Contested Divorce?
Almost any matter the court must address can become a point of contention. Some disputes arise from genuine disagreement about what is fair; others stem from different interpretations of the facts or different priorities.
Financial and Property Disagreements
Property and debt division generate significant disputes in many divorces. Illinois follows equitable distribution, meaning courts divide marital property in “just proportions” rather than automatically splitting everything equally. Spouses often disagree about what constitutes a fair division.
Child-Related Disputes
When children are involved, parents may have fundamentally different views about living arrangements, decision-making authority, and parenting time schedules. These disputes frequently make divorces contested.
Support and Maintenance Conflicts
Disagreements about financial support—both child support and spousal maintenance—can prevent settlement. Disputes often center on income calculations, duration of support, or whether maintenance is appropriate at all.
Common issues that create contested status include:
- Classification of property as marital or non-marital, particularly for assets acquired before marriage or received as gifts or inheritance
- Valuation of significant assets such as real estate, retirement accounts, or business interests
- Division of marital debt and responsibility for joint obligations
- Allocation of parental responsibilities, including major decision-making authority for education, healthcare, and religious upbringing
- Parenting time schedules and how children will divide time between households
- Child support calculations, especially when income is disputed or a parent is self-employed
- Whether spousal maintenance is appropriate and, if so, the amount and duration
- Responsibility for attorney’s fees and litigation costs
How Does the Contested Divorce Process Work in Illinois?
The contested divorce process follows a structured path from filing through resolution. Understanding these stages helps you know what to expect and when.
Filing and Initial Response
One spouse initiates the divorce by filing a verified petition for dissolution with the circuit court. Under 750 ILCS 5/403, this petition must include specific information about both parties, the marriage, any children, and the relief sought. The filing spouse must have been an Illinois resident for at least 90 days.
After filing, the petition must be served on the other spouse, who then has 30 days to file an appearance and answer. The responding spouse should also file a counter-petition to preserve their own claims. According to In re Marriage of Leopando, 96 Ill. 2d 114, 449 N.E.2d 137 (Ill. 1983), dissolution constitutes a single claim, and filing a counter-petition protects the responding spouse if the petitioner later decides to dismiss.
Temporary Orders and Interim Relief
Contested divorces often take months or longer to resolve. During this time, courts can enter temporary orders addressing immediate needs. Under 750 ILCS 5/501, courts have “wide latitude” to award temporary maintenance, child support, and other relief based on summary hearings using financial affidavits.
As explained in In re Marriage of Hochstatter, 2020 IL App (3d) 190132, 152 N.E.3d 1045 (Ill. App. 3rd Dist. 2020), the principal purpose of temporary orders is “to balance the equities between the parties as fairly as possible while the dissolution case is pending.” These orders do not prejudice the final outcome and terminate when the court enters its final judgment.
Discovery and Financial Disclosure
Contested divorces require both parties to exchange comprehensive financial information. Under 750 ILCS 5/501(a)(1), both spouses must serve completed financial affidavits on standardized statewide forms, supported by documentation including tax returns, pay stubs, and bank statements.
Beyond mandatory disclosure, parties in contested cases can use the full range of civil discovery tools: interrogatories (written questions), requests for production of documents, depositions (sworn testimony), and requests to admit facts. As stated in Williams v. A.E. Staley Manufacturing Co., 83 Ill. 2d 559 (Ill. 1981), “Discovery is not a tactical game… Discovery is intended as, and should be a cooperative undertaking.”
Courts take discovery obligations seriously. Intentional or reckless inaccuracies in financial affidavits require sanctions under the statute.
Negotiation and Settlement Attempts
Even in contested cases, the process includes multiple opportunities for settlement. Parties may negotiate directly, work through their attorneys, or participate in mediation. Many courts require settlement conferences before allowing cases to proceed to trial.
The key procedural stages in a contested divorce include:
- Filing the petition for dissolution and serving it on the other spouse
- Filing an appearance, answer, and counter-petition within 30 days of service
- Seeking temporary orders for support, exclusive possession, or other interim relief as needed
- Completing mandatory financial disclosure and conducting formal discovery
- Participating in negotiation, mediation, or court-ordered settlement conferences
- Attending pretrial conferences to narrow issues and prepare for trial if settlement fails
- Proceeding to trial for judicial determination of unresolved issues
How Long Does a Contested Divorce Take in Illinois?
There is no single answer to how long a contested divorce will take. Timelines vary dramatically based on the complexity of the issues, the level of conflict between the parties, and the court’s schedule.
Factors That Affect Your Timeline
Several variables influence how long your contested divorce will last. Complex financial situations requiring expert valuation take longer than straightforward cases. High-conflict custody disputes add time for evaluations and hearings. Courts in different counties have different caseloads and scheduling practices.
The extent of discovery also matters. Cases requiring depositions of multiple witnesses, subpoenas to third parties, or forensic accounting analysis naturally take longer than those resolved with basic document exchanges.
Why Most Contested Cases Settle Before Trial
Despite the “contested” label, the vast majority of divorces resolve through negotiation rather than trial. According to U.S. Census Bureau data cited in Court Statistics Project analyses (2024-2025), approximately 95% of divorces are uncontested or settle before trial.
This figure reflects an important reality: a divorce that starts contested often becomes effectively uncontested when the parties reach agreement. The discovery process itself frequently facilitates settlement by ensuring both parties have complete information about the marital estate.
Can a Contested Divorce Become Uncontested?
Yes. A contested divorce can become uncontested at any point before trial when the parties reach a comprehensive agreement. This happens frequently.
Settlement Opportunities Throughout the Process
Settlement can occur during informal negotiations, formal mediation, or even on the courthouse steps before trial begins. Some couples settle all issues; others narrow their disputes and ask the court to decide only the remaining contested matters.
When spouses reach agreement, they formalize their terms in a marital settlement agreement (MSA). Under 750 ILCS 5/502, these written agreements are binding contracts. Once incorporated into the divorce judgment, an MSA becomes enforceable both as a court order and as contract terms. As noted in In re Marriage of Bielawski, 328 Ill. App. 3d 243, 764 N.E.2d 1254 (Ill. App. 1st Dist. 2002), “All presumptions are in favor of the validity of the settlement.”
Benefits of Reaching Agreement
Settling a contested divorce offers several advantages over proceeding to trial. You maintain control over the outcome rather than leaving decisions to a judge who does not know your family. Settlement typically costs less in attorney’s fees and takes less time than full litigation. Perhaps most importantly, negotiated agreements often work better in practice because both parties had input in creating them.
Settlement also reduces conflict, which matters especially when children are involved. Parents who can cooperate during divorce are better positioned to co-parent effectively afterward.
What Happens If a Contested Divorce Goes to Trial?
When settlement is not possible, the court will conduct a trial to resolve the disputed issues. Illinois family law trials follow the Illinois Rules of Evidence, with preponderance of the evidence as the general standard for most determinations.
Presenting Evidence and Testimony
At trial, each party presents evidence supporting their position on the contested issues. This includes testimony from the parties themselves, testimony from other witnesses, and documentary evidence such as financial records, appraisals, and other relevant documents.
A contested divorce trial typically involves:
- Opening statements from each party’s attorney outlining their position
- Direct examination of witnesses, including the parties themselves
- Cross-examination to test the credibility and accuracy of testimony
- Expert witness testimony when specialized knowledge is required for valuation or other technical issues
- Introduction of documentary evidence including financial records, property appraisals, and other relevant documents
- Closing arguments summarizing the evidence and advocating for specific outcomes
How the Judge Decides
The judge evaluates the evidence and applies Illinois law to reach decisions on each contested issue. In dividing property, the court considers the statutory factors under 750 ILCS 5/503(d) and divides marital property in “just proportions.” For parental responsibilities, the court focuses on the children’s best interests. For maintenance, the court applies the statutory factors and guidelines.
As explained in In re Marriage of Abu-Hashim, 2014 IL App (1st) 122997, 14 N.E.3d 524 (Ill. App. 1st Dist. 2014), “Equitable division depends on more than merely an analysis of dollars and cents.” The court’s observations of the parties and assessment of credibility play a significant role in contested cases.
The Final Judgment
After trial, the court enters a judgment for dissolution of marriage that resolves all contested issues. This judgment is a binding court order. Property provisions in the judgment are never modifiable, while support and parental responsibility provisions may be modified upon a showing of substantial change in circumstances.
Either party may appeal the judgment, but appeals are limited. Most family law determinations are reviewed only for abuse of discretion, meaning the appellate court will not substitute its judgment for the trial court’s unless the ruling was arbitrary, fanciful, or unreasonable.
Frequently Asked Questions
Does a contested divorce always go to trial in Illinois?
No. While the contested label means you and your spouse disagree about one or more issues, the vast majority of contested cases settle before trial. The discovery process, negotiation, mediation, and pretrial conferences all provide opportunities to reach agreement. Only a small percentage of divorces ultimately require a judge to decide the disputed issues after a full trial.
Can we change from contested to uncontested during the process?
Yes. A contested divorce becomes effectively uncontested whenever the parties reach a comprehensive settlement agreement. This can happen at any stage of the proceedings. Many couples who initially disagree find common ground after completing financial disclosure, participating in mediation, or simply having time to consider their options more carefully.
What if my spouse refuses to respond to the divorce petition?
If your spouse fails to file an appearance and answer within 30 days of service, you may be able to obtain a default judgment. However, courts generally prefer to decide cases on the merits. A spouse who initially fails to respond may later seek to set aside a default judgment, particularly if they can show good cause for the delay.
Is Illinois a no-fault state even for contested divorces?
Yes. Illinois eliminated fault-based divorce grounds effective January 1, 2016. The sole ground for dissolution is that irreconcilable differences have caused the irretrievable breakdown of the marriage. This applies whether your divorce is contested or uncontested. The court will not consider marital misconduct when dividing property or making support determinations.
What happens to finances while a contested divorce is pending?
Courts can enter temporary orders addressing financial needs during the divorce process. These orders may include temporary maintenance, temporary child support, payment of household expenses, and interim attorney’s fees. The purpose is to maintain stability and balance the equities while the case proceeds toward final resolution.
