Divorce • Parenting • Support • Property

Illinois family-law cases often involve several issues at the same time: ending the marriage, dividing property and debts, determining support, and—when children are involved—allocating parenting time and decision-making responsibilities.

What Are the Basic Illinois Divorce Requirements?

Illinois law imposes residency requirements before a court may enter a divorce. Whether the requirement is satisfied depends on the parties’ circumstances and the current statute. Illinois uses irreconcilable differences rather than traditional fault grounds.

If spouses have lived separate and apart for at least six continuous months immediately before entry of judgment, Illinois law creates an irrebuttable presumption that the irreconcilable-differences requirement has been met.

What Is the Difference Between Contested and Uncontested Divorce?

An uncontested divorce generally means the spouses have resolved the issues that must be addressed. A contested case requires negotiation, motion practice, mediation, hearings or trial on one or more disputed issues.

How Does Illinois Divide Property and Debt?

Illinois distinguishes marital property from non-marital property. Property and debts acquired during the marriage are generally presumed marital unless a statutory exception applies, such as certain gifts, inheritances or qualifying premarital property.

The court divides marital property in just proportions after considering the statutory factors. That does not necessarily mean 50/50.

How Is Parenting Time Decided?

Illinois courts allocate parenting time according to the child’s best interests. The statute considers factors such as the child’s needs, past caretaking, adjustment to home and school, the parents’ schedules and distance between residences, and other relevant circumstances.

The law generally presumes both parents are fit unless the evidence supports restrictions under the statutory standards.

Who Makes Major Decisions for a Child?

Illinois refers to this as allocation of significant decision-making responsibilities. Major areas can include education, health care, religion and extracurricular activities. The court can allocate responsibility to one parent or both based on the child’s best interests.

How Is Child Support Determined?

Illinois uses statutory child-support guidelines that consider the parents’ incomes and parenting arrangement, along with health insurance, child-care costs and other expenses or circumstances addressed by the statute.

The correct calculation depends on the actual income information and parenting schedule.

Is Maintenance Automatic?

No. The court first determines whether maintenance is appropriate after considering factors such as income, property, needs, earning capacity, impairment of earning capacity, duration of the marriage and other statutory considerations.

If maintenance is appropriate, guideline rules may apply in qualifying cases; other cases may require a non-guideline analysis.

What Are Temporary Orders?

While a divorce or family case is pending, temporary orders can address issues such as parenting time, decision-making, support, maintenance, possession of property and other immediate needs until a final judgment is entered.

Can Orders Be Modified Later?

Some parenting, support and maintenance orders can be modified when statutory requirements are satisfied. Property provisions in a divorce judgment are generally final rather than routinely modifiable.

Where Does Mediation Fit?

Mediation can help parties resolve parenting, financial or other disputes without requiring the judge to decide every issue. It can reduce conflict and narrow disagreements, but a mediator does not replace independent legal advice for either party.

What Information Can Be Useful at a Family-Law Consultation?

Useful information can include court papers, prior orders, income information, tax returns, property and debt statements, retirement-account information, deeds, parenting schedules and any written agreements already discussed.

Quick Answers

Illinois Family Law & Divorce FAQ Questions

General information only. The facts and documents in each matter can change the answer.

How long must someone live in Illinois before getting divorced?

Illinois law imposes residency requirements before a court may enter a divorce. Whether the requirement is satisfied depends on the parties’ circumstances and the current statute.

Does Illinois require fault to get divorced?

No. Illinois dissolution law is based on irreconcilable differences causing the irretrievable breakdown of the marriage.

What is the difference between contested and uncontested divorce?

An uncontested divorce generally means the spouses have reached agreement on the issues that must be resolved. A contested case requires the court to decide one or more disputed issues.

How is property divided in an Illinois divorce?

Illinois distinguishes marital and non-marital property and divides marital property in just proportions after considering statutory factors. That does not necessarily mean an equal 50/50 division.

How does Illinois decide parenting time?

Illinois courts allocate parenting time according to the child's best interests. The statute directs courts to consider multiple factors, including past caretaking, the child's needs, adjustment, distance between homes and other relevant circumstances.

Who makes major decisions for a child after divorce?

Illinois calls this allocation of significant decision-making responsibilities. Education, health, religion and extracurricular activities can be allocated to one or both parents according to the child's best interests.

Is maintenance automatic in an Illinois divorce?

No. The court first decides whether maintenance is appropriate after considering statutory factors. If maintenance is appropriate, guideline or non-guideline rules may apply depending on the circumstances.

Can a parenting or support order be changed later?

Sometimes. Illinois law permits modification of certain orders when statutory requirements are met. Property provisions of a divorce judgment are generally not modifiable.

Does mediation replace a divorce attorney?

No. Mediation can help parties resolve disputed issues, but the mediator does not act as each party's individual advocate. A party may still want independent legal advice before agreeing to final terms.
