Divorce

Residency Requirement (90 days)

To get divorced in Illinois, the law generally requires that one spouse has lived in Illinois (or been stationed in Illinois as a member of the armed services) for at least 90 days when the case is filed or when the court makes the finding. 

No-Fault Divorce: “Irreconcilable Differences”

Illinois dissolves a marriage based on irreconcilable differences causing an irretrievable breakdown, where reconciliation has failed or isn’t practical. 

The 6-Month Separation Presumption

If spouses have lived separate and apart for at least 6 continuous months before the divorce judgment, Illinois law creates an irrebuttable presumption that the irreconcilable-differences requirement is met. 

Illinois Divorce Process: Step-by-Step

Most Illinois divorce cases follow a predictable path, even when emotions are high:

1. File a Petition for Dissolution of Marriage
2. Serve the other spouse (or proceed by appearance/waiver where appropriate)
3. Request temporary orders if immediate stability is needed (parenting schedule, support, bills, possession of the home) 
4. Exchange required financial information and, when necessary, conduct discovery
5. Address parenting issues through a proposed parenting plan (if children)
6. Negotiate settlement (often through attorney-led negotiation, mediation, or case management)
7. If no agreement: trial and then entry of a final judgment
8. Finalize the divorce through a Judgment of Dissolution of Marriage

Why this matters: When you understand the sequence, you stop reacting, and start making decisions that protect your long-term outcome.

Uncontested vs. Contested Divorce in Illinois

Uncontested Divorce

An uncontested divorce in Illinois typically means you and your spouse agree on the major terms (property, debt, support, and parenting if applicable). This can reduce time, cost, and conflict, as long as the agreement is complete and enforceable.

Contested Divorce

A contested divorce means there is disagreement on one or more core issues. These cases require stronger evidence planning, tighter financial analysis, and a court-ready strategy from the start.

What Illinois Divorce Typically Decides

An Illinois divorce usually resolves (or properly reserves) the following:

Parenting (If You Have Children)

Illinois generally frames “custody” as the allocation of parental responsibilities (decision-making) and parenting time. (If you want this page to match your custody page exactly, we can cross-link those sections for SEO and user flow.)

Property and Debt Division

Illinois divides marital property in “just proportions” and distinguishes marital vs. non-marital property under statute, an area where documentation and tracing can be decisive. 

Spousal Maintenance (Alimony)

Illinois uses the legal term maintenance (commonly called “alimony”). In many cases, statutes provide guideline calculations and caps, but outcomes still depend heavily on the facts. 

Temporary Orders: Getting Stability While the Case Is Pending

Divorce takes time, and life keeps moving. Illinois allows parties to seek temporary relief during the case, including temporary support/maintenance and other interim orders. 

Temporary orders often matter because they can stabilize:

• a workable parenting schedule,
• financial support and bill payment,
• use/possession of the home or vehicles,
• and the day-to-day structure while the case progresses.

Common Mistakes in Illinois Divorce (And How We Help You Avoid Them)

Divorce outcomes can be damaged by avoidable missteps, like:

• Making big financial moves without a plan (draining accounts, new debt, major purchases)
• Informal parenting arrangements that become “the new normal” without protections
• Poor documentation of income, expenses, and contributions
• Agreeing too quickly to “keep the peace” without understanding long-term cost
• Using texts/social media in ways that can be misinterpreted or used against you

Our job is to keep you steady and strategic when the process feels emotionally loud.

Why Hiring a Divorce Lawyer Can Change the Outcome

A strong divorce strategy isn’t about fighting, it’s about clarity, leverage, and protection:

• identifying the issues that truly drive value (parenting stability, maintenance exposure, asset division),
• building the evidence early,
• negotiating from a position of preparation,
• and ensuring your final judgment is enforceable and future-proof.
