A divorce without children in Illinois is the simplest form of dissolution the state offers. At least one spouse must live in Illinois for 90 consecutive days before judgment, the sole ground is irreconcilable differences, filing fees range from $250 to $388, and eligible couples can finalize in 30-90 days through Joint Simplified Dissolution under 750 ILCS 5/452.
Without minor children, an Illinois divorce skips the most contested and time-consuming issues entirely: parental responsibilities (custody), parenting time, and child support. The court's remaining tasks are dividing marital property, deciding whether spousal maintenance applies, and entering the Judgment for Dissolution of Marriage. This guide explains every step of a childless divorce in Illinois, from residency and grounds to filing fees, property division, and the fast-track simplified procedure that can end an uncontested no-kids case in about a month.

Residency Requirements for Divorce Without Children in Illinois
To divorce in Illinois, at least one spouse must have lived in the state for 90 consecutive days immediately before the court enters judgment, under 750 ILCS 5/401(a). Only one spouse needs to meet this 90-day requirement — both parties do not need to reside in Illinois. Military members stationed in Illinois for 90 or more days also satisfy the residency rule even if their legal residence is another state.
A critical nuance separates filing from judgment. The 90-day requirement applies to when the court may enter a final judgment, not when you may file the petition. You can file your Petition for Dissolution of Marriage before completing 90 days of residency, but the judge cannot finalize the divorce until at least one spouse has been an Illinois resident for the full 90 days. There is no separate pre-filing waiting period under the statute. This structure lets couples begin the paperwork immediately while the residency clock runs, which matters most for people who recently moved to Illinois and want to start a childless divorce without delay.
Venue is a separate question from residency. Under 750 ILCS 5/104, the case is filed in the county where either spouse resides. If the two spouses live in different Illinois counties, the petitioner may choose either county. There is no additional county-level residency waiting period beyond the statewide 90-day rule, so a childless couple can file in whichever county's circuit court is most convenient for both parties.
Grounds for a No-Kids Divorce in Illinois
Illinois recognizes exactly one ground for divorce: irreconcilable differences that have caused the irretrievable breakdown of the marriage, under 750 ILCS 5/401(a). As of January 1, 2016, Illinois eliminated all fault-based grounds — adultery, mental cruelty, desertion, habitual drunkenness, and the rest — making it a pure no-fault state. Neither spouse must prove wrongdoing to obtain a divorce, and neither can block the divorce by contesting the grounds.
The 6-month separation rule is the practical mechanism for proving irreconcilable differences. If spouses have lived separate and apart for a continuous 6-month period, 750 ILCS 5/401(a-5) creates an irrebuttable presumption that irreconcilable differences exist — meaning the court must accept them and no further proof is required. Importantly, spouses can qualify as living "separate and apart" while still residing under the same roof, provided they maintain genuinely separate lives. For a divorce without children in Illinois, this presumption often removes the last procedural hurdle, because a childless couple who both agree the marriage is over can simply attest to irreconcilable differences without waiting the full six months.
Marital misconduct does not affect the outcome of a no-fault Illinois divorce. Because fault grounds no longer exist, courts do not weigh abuse, abandonment, or adultery when dividing property — with one narrow exception. If a spouse has "dissipated" marital assets, meaning spent marital money for a non-marital purpose during the breakdown of the marriage, the court may account for that dissipation when dividing the estate under 750 ILCS 5/503. Outside of dissipation, a childless divorce proceeds on economics and paperwork alone, not blame.
Filing Fees and Court Costs
The filing fee for a divorce in Illinois ranges from $250 to $388 depending on the county, with Cook County charging the highest rate at $388 and DuPage County charging approximately $348. These fees cover the petitioner's initial Petition for Dissolution of Marriage; the responding spouse pays a separate appearance fee, typically $200-$250, unless the case is filed jointly. Filing fees are current as of January 2026 and change periodically — verify the exact amount with your county circuit clerk before filing.
For low-income filers, Illinois offers a fee waiver. A person who cannot afford court costs may file an Application for Waiver of Court Fees, and if the court finds the applicant qualifies based on income and public-benefit status, the entire filing fee is waived. This removes the single largest mandatory cost for a childless divorce, which is often the only court expense in an uncontested no-kids case that uses standardized forms.
Beyond the filing fee, a divorce without children in Illinois can carry additional costs depending on complexity. A fully uncontested childless divorce handled without lawyers may cost only the filing fee — roughly $250 to $388 total. An uncontested case with limited attorney assistance to draft a Marital Settlement Agreement typically runs $1,000 to $3,500. A contested childless divorce, where spouses dispute property division or maintenance, can cost $5,000 to $15,000 or more per side once attorney hourly fees, discovery, and court appearances accumulate. Because no-kids cases avoid custody evaluations and child-support litigation, they remain the least expensive category of Illinois divorce.
| Cost Category | Typical Total (Childless Divorce) |
|---|---|
| Court filing fee (petitioner) | $250-$388 |
| Response/appearance fee (spouse) | $200-$250 |
| Uncontested, no attorney (DIY forms) | Filing fee only (~$250-$388) |
| Uncontested, limited attorney help | $1,000-$3,500 |
| Contested (property/maintenance disputes) | $5,000-$15,000+ per side |

Joint Simplified Dissolution: The Fast Track for Childless Couples
Joint Simplified Dissolution under 750 ILCS 5/452 is Illinois's expedited divorce procedure, available only to couples with no children who meet strict financial limits, and it can finalize a divorce in as little as 30 days. This is the single biggest advantage of divorcing without children in Illinois: the simplified track is legally unavailable to any couple who has minor children, so childless spouses have access to a faster, cheaper path that other divorcing couples do not.
To qualify for Joint Simplified Dissolution, a couple must satisfy every one of the statute's requirements. No children were born of or adopted during the marriage, and the wife is not knowingly pregnant. The marriage lasted 8 years or less. At least one spouse meets the 90-day residency rule. Neither party owns any interest in real property, and neither has retirement benefits except IRAs with a combined value under $10,000. The total fair market value of all marital property, after deducting encumbrances, is less than $50,000. The combined gross annualized income of both parties is less than $60,000, and neither party individually earns more than $30,000 gross annually. Both parties waive spousal maintenance, have fully disclosed all assets, liabilities, and tax returns, and have signed a written agreement allocating any companion animals.
The simplified process itself is streamlined. Both spouses file a joint petition using standardized court forms supplied by the circuit clerk, submit a written property-division agreement, and appear together before a judge. At the hearing, they file an affidavit under 750 ILCS 5/454 confirming that all property has been divided and all required documents executed. No attorney is required. The tradeoff is the low income ceiling: because the individual cap is $30,000 gross annually — roughly the earnings of a full-time Chicago minimum-wage worker at $15/hour — many childless couples exceed the threshold and must instead use the standard dissolution track under 750 ILCS 5/401.
Property Division in a Divorce Without Children
Illinois divides marital property through equitable distribution under 750 ILCS 5/503, meaning the court splits assets in "just proportions" — which is fair but not automatically equal, and not a presumed 50/50 division. Illinois is not a community property state. Judges weigh statutory factors and may order a 60/40, 70/30, or other split. In a childless divorce, property division is usually the central and often the only contested issue the court must resolve.
The process begins with classification. Under 750 ILCS 5/503(a), all property acquired by either spouse after the marriage and before the judgment is presumed marital property, regardless of whose name is on the title. Non-marital property includes assets acquired before the marriage, gifts, inheritances, property exchanged for non-marital assets, and anything excluded by a valid prenuptial or postnuptial agreement. When classification is unclear, 750 ILCS 5/503(b) resolves doubts in favor of marital property. Only marital property gets divided; each spouse keeps their own non-marital property.
After classification, the court divides marital property using twelve statutory factors under 750 ILCS 5/503(d). These include each spouse's contribution to acquiring or preserving the estate (including homemaker contributions), dissipation of assets, the duration of the marriage, each party's economic circumstances and future earning capacity, obligations from prior marriages, any prenuptial agreement, the age and health of each spouse, whether the division substitutes for maintenance, and the tax consequences of the split. For a no-dependents divorce, the shorter the marriage and the fewer commingled assets, the closer the division typically lands to 50/50 — which is why many simple childless divorces settle quickly without litigation.
Spousal Maintenance in a Childless Illinois Divorce
Spousal maintenance (alimony) in Illinois is calculated under a statutory formula in 750 ILCS 5/504: 33.3% of the payer's net annual income minus 25% of the recipient's net annual income, capped so the recipient's total does not exceed 40% of the couple's combined net income. This guideline formula applies when the couple's combined gross annual income is under $500,000 and the payer has no prior support obligations. Above $500,000, the court sets maintenance at its discretion.
Maintenance is not automatic in any divorce, including a childless one. Before applying the formula, the court must first decide whether an award is even appropriate by weighing 14 factors under 750 ILCS 5/504(a), including each spouse's income, needs, earning capacity, and the standard of living established during the marriage. In many short, childless marriages where both spouses earn comparable incomes, the court finds maintenance unwarranted and awards none. When maintenance does apply, its duration is set by multiplying the marriage length by a statutory factor: 20% of the marriage length for marriages of 5 years or less, 40% for 5-10 years, 60% for 10-15 years, and 80% for 15-20 years.
A worked example illustrates the formula. Suppose the paying spouse has $100,000 in net annual income and the receiving spouse has $40,000. The calculation is 33.3% of $100,000 ($33,300) minus 25% of $40,000 ($10,000), producing $23,300 in annual maintenance. Added to the recipient's $40,000, the total of $63,300 stays below 40% of the combined $140,000 net income ($56,000)... in this case the 40% cap would actually reduce the award, since $40,000 plus $23,300 exceeds $56,000, so the court would cap maintenance at $16,000. This cap interaction shows why the guideline is a starting point, not a guaranteed result, and why couples seeking a truly simple divorce often waive maintenance entirely.
The Step-by-Step Divorce Process Without Children in Illinois
A divorce without children in Illinois follows a defined sequence that, for an uncontested case, can conclude in 30 to 90 days once the 90-day residency requirement is met. Because there are no custody or child-support determinations, the timeline compresses dramatically compared to a divorce involving minor children, which routinely takes 12 to 18 months when contested.
The standard process runs through these steps:
- Confirm residency and grounds. Verify that at least one spouse meets the 90-day Illinois residency rule and that both agree the marriage is irretrievably broken by irreconcilable differences.
- Prepare and file the petition. The petitioner files a Petition for Dissolution of Marriage with the circuit clerk in the appropriate county and pays the $250-$388 filing fee (or files a fee-waiver application).
- Serve the other spouse. The respondent is served with the petition and summons, or signs an Entry of Appearance and Waiver if the divorce is amicable and joint.
- Exchange financial disclosures. Both spouses complete a Financial Affidavit disclosing income, assets, debts, and expenses — the foundation for property division and any maintenance analysis.
- Negotiate a Marital Settlement Agreement. The spouses agree in writing on how to divide marital property and debts and whether either waives maintenance. In a no-kids case this is the core document.
- Attend the prove-up hearing. A brief court hearing where the judge confirms the agreement is fair, the grounds are met, and enters the Judgment for Dissolution of Marriage.
For couples who qualify, the Joint Simplified Dissolution track under 750 ILCS 5/452 collapses these steps into a single joint filing and one shared hearing, often finalizing in about 30 days. For couples who exceed the simplified income limits but still agree on everything, the standard uncontested path typically resolves in 60 to 90 days, making a childless Illinois divorce among the fastest dissolution processes in the country.
