Illinois residents can legally divorce an incarcerated spouse by filing a Petition for Dissolution of Marriage in any circuit court where either spouse resides or where the correctional facility is located. The process requires meeting a 90-day residency requirement, paying filing fees ranging from $250 to $388 depending on county, and serving divorce papers through the Illinois Department of Corrections (IDOC) facility administration. Illinois operates as a no-fault divorce state under 750 ILCS 5/401, meaning irreconcilable differences serve as the only ground for dissolution regardless of whether your spouse is incarcerated.

How Illinois Law Addresses Prison Divorce in 2026
Illinois law permits any spouse to file for divorce regardless of whether their partner is incarcerated in a state prison, federal facility, or county jail. Under 750 ILCS 5/401, Illinois abolished all fault-based grounds in 2016, making irreconcilable differences the sole basis for dissolution. Your spouse's imprisonment does not constitute a separate ground for divorce, but it strongly supports the claim that your marriage has irretrievably broken down with no prospect of reconciliation. Illinois courts process approximately 28,000 divorce cases annually, with prison divorces representing a small but significant subset requiring specialized procedures.
The Illinois Marriage and Dissolution of Marriage Act (IMDMA) underwent significant amendments in 2025 affecting incarcerated spouses. Previously, spousal maintenance (alimony) automatically stopped accruing when the paying spouse was imprisoned. Under current law effective January 2025, maintenance continues to accrue during incarceration, and unpaid amounts become legally enforceable arrears collectible after release. This change means divorcing an incarcerated spouse now carries different financial implications than before.
Residency Requirements for Filing
At least one spouse must have been a resident of Illinois or stationed in Illinois as a member of the armed forces for a minimum of 90 days before the court can enter a judgment of dissolution under 750 ILCS 5/401(a). Illinois has no pre-filing waiting period, allowing you to file your petition immediately upon meeting the residency threshold. If your incarcerated spouse was an Illinois resident before imprisonment and remains housed in an Illinois correctional facility, you may file in the county where the prison is located or in your county of residence.
The 90-day requirement applies to the time of judgment entry, not filing. You may file your petition before reaching 90 days if you will meet the requirement before your case concludes. Given that most contested divorces take 6-18 months to finalize, residency rarely presents practical obstacles for spouses divorcing incarcerated partners.
Step-by-Step Filing Process
Filing for divorce when your spouse is incarcerated follows the standard Illinois procedure with modifications for service of process. The process typically takes 3-12 months depending on whether the incarcerated spouse contests the divorce, with uncontested cases resolving faster.
Step 1: Prepare Your Petition
Complete the Petition for Dissolution of Marriage, which must include specific information required by 750 ILCS 5/403: the age, occupation, and residence of each party; length of residence in Illinois; date and place of marriage; names, ages, and addresses of all minor children; a statement that jurisdictional requirements have been met; and proposed arrangements for support, parenting responsibilities, and maintenance. Illinois courts provide standardized forms through the Illinois Courts website at ilcourts.info/forms.
Step 2: File with the Circuit Court
File your petition with the circuit court clerk in the county where either spouse resides or where the correctional facility is located. Filing fees vary significantly by county: Cook County charges $388, DuPage County charges $348, Madison County charges approximately $314, and most other counties fall within the $250-$400 range. As of March 2026, verify current fees with your local circuit clerk before filing.
Step 3: Serve Your Incarcerated Spouse
Service of process on an incarcerated spouse requires coordination with the correctional facility. Contact the chief administrative officer or warden of the facility where your spouse is housed to arrange service. The IDOC website provides an Individual in Custody Search tool to locate your spouse and identify the correct facility contact information. A facility representative will accept service during regularly scheduled business hours and provide you with a signed affidavit confirming delivery.
Step 4: Wait for Response or Default
Your spouse has 30 days from service to file an appearance and response. If they fail to respond within this timeframe, you may file a motion for default judgment. Incarcerated spouses can participate in proceedings via telephone, video conference, or through legal representation. Many incarcerated individuals qualify for appointed counsel through the state defender's office or legal aid organizations.
Step 5: Attend the Prove-Up Hearing
If your spouse defaults or agrees to an uncontested divorce, you will attend a prove-up hearing where you present testimony supporting your petition. For default cases, the judge bases their decision solely on your testimony since no one appears to contradict your statements. Contested cases proceed to trial with the incarcerated spouse participating remotely or through counsel.
Serving Divorce Papers Through IDOC
Serving an incarcerated spouse requires following specific protocols established by the Illinois Department of Corrections. Traditional service methods like mailing or personal delivery at a residence do not apply. The process server must contact the chief administrative officer of the facility to arrange a designated time and date during regular business hours when a facility representative will meet with and accept service.
IDOC requires that service be arranged in advance rather than showing up unannounced at a correctional facility. Locate your spouse using the IDOC Individual in Custody Search at idoc.illinois.gov, which provides current housing location and facility contact information. Contact the facility legal office to confirm their specific service protocols, as procedures may vary between state prisons, federal facilities, and county jails.
After successful service, obtain proof of service documentation from the facility. This typically includes an affidavit or signed confirmation form from the sheriff or prison official confirming that the divorce papers reached the inmate. File this proof of service with the court before proceeding with your case.
Property Division When a Spouse Is Incarcerated
Illinois follows equitable distribution principles under 750 ILCS 5/503, meaning marital property is divided in just proportions rather than automatically 50/50. Courts consider twelve statutory factors when dividing assets, including each party's contribution to the marital estate, the duration of the marriage, economic circumstances of each spouse, and any dissipation of marital property.
Incarceration affects property division in several ways. An incarcerated spouse's reduced earning capacity and economic circumstances influence what courts consider a just distribution. Courts may award the non-incarcerated spouse a larger share of marital property to account for sole responsibility for household expenses, child-rearing costs, and the practical difficulties of managing shared assets with an imprisoned partner.
All property acquired during the marriage is presumed marital property under Illinois law. Non-marital property includes assets owned before marriage, inheritances, and gifts received by one spouse alone. However, commingling non-marital funds with marital accounts can convert them to marital property subject to division. Criminal restitution obligations and fines incurred by the incarcerated spouse are generally considered non-marital debt, meaning the non-incarcerated spouse typically does not bear responsibility for these obligations.
Child Custody and Parenting Time Considerations
Illinois replaced the terms custody and visitation with allocation of parental responsibilities under 750 ILCS 5/602. Courts allocate two categories: decision-making responsibilities covering major life decisions in education, health, religion, and extracurricular activities, and parenting time governing physical time with the child.
Incarceration significantly impacts parenting time allocation. Under 750 ILCS 5/602.7, courts must consider the child's best interests when allocating parenting time, including the amount of time each parent previously spent performing caretaking functions, the child's adjustment to home and school, and each parent's willingness to facilitate a relationship with the other parent.
Courts do not automatically terminate parenting rights based on incarceration alone. However, judges may restrict parenting time if exercise of that time would seriously endanger the child's physical, mental, moral, or emotional health. For incarcerated parents, parenting time often takes the form of supervised prison visits, video calls, or written correspondence depending on facility rules and the child's age and preferences.
Spousal Maintenance and the 2025 IMDMA Changes
The 2025 amendments to the Illinois Marriage and Dissolution of Marriage Act fundamentally changed how maintenance operates when a paying spouse is incarcerated. Previously, maintenance automatically stopped accruing during imprisonment. Under current law, maintenance continues to accrue even while the paying spouse is imprisoned, and unpaid amounts become legally enforceable arrears collectible after release.
This change carries significant implications for both parties in a prison divorce. If you are the spouse entitled to receive maintenance, you can accumulate arrears during your former spouse's incarceration and pursue collection upon their release through wage garnishment, liens, or other enforcement mechanisms under Illinois law. If your incarcerated spouse owes you maintenance, document the accruing debt and consult with an attorney about enforcement options.
Incarcerated spouses who genuinely cannot pay must actively petition the court for a modification. The automatic pause is gone, meaning failure to seek modification results in accumulating debt. Courts retain discretion to adjust obligations based on genuine inability to pay, but they no longer do so automatically.
Default Judgment When Your Spouse Does Not Respond
Illinois courts may enter a default judgment if your incarcerated spouse fails to respond within 30 days after proper service. Before filing a motion for default, ensure you have properly served your spouse through the correctional facility and obtained proof of service documentation. The sheriff's affidavit or prison official's confirmation form must be filed with the court.
Once the 30-day response period expires without an appearance, file your motion for default with the circuit court. You must also file an affidavit stating that your spouse is not in military service, as federal law protects service members from default judgments when serving their country. The divorce case then proceeds to a prove-up hearing where you present oral testimony supporting your requested relief.
At the prove-up hearing, the judge accepts your uncontested testimony regarding property division, child custody arrangements, and any maintenance requests. Since no one appears to contradict your statements, courts generally grant reasonable requests that comply with Illinois law. However, judges retain discretion to modify proposals that appear unfair or inconsistent with statutory requirements.
An incarcerated spouse can challenge a default judgment by filing a motion to vacate within 30 days under 735 ILCS 5/2-1301(e), which courts grant relatively easily. After that 30-day window closes, they may file a petition to vacate under 735 ILCS 5/2-1401 within 2 years, but must demonstrate due diligence and a meritorious defense, which presents a higher bar to overcome.
Filing Fee Waivers for Financial Hardship
Illinois Supreme Court Rule 298 allows fee waivers for those who cannot afford court costs. If your household income falls at or below 125% of the federal poverty guidelines, you qualify for a full fee waiver. For a single person in 2026, this threshold equals $19,950 annually or $1,662.50 monthly.
Partial fee waivers apply at higher income levels: 75% waiver for income up to $23,940, 50% waiver up to $27,930, and 25% waiver up to $31,920. If you receive Supplemental Security Income (SSI), Temporary Assistance for Needy Families (TANF), SNAP benefits, or Medicaid, you automatically qualify for a full fee waiver without providing additional income documentation.
To apply, complete the Application for Waiver of Court Fees (form FW-CIV), available at ilcourts.info/forms or through Illinois Legal Aid Online. The court either rules on your application or sets a hearing requiring you to appear with supporting documentation. If approved, the waiver covers the filing fee, service costs, and other court fees that might otherwise total $400-$600 in a typical divorce case.
Joint Simplified Dissolution Alternative
Illinois offers a streamlined Joint Simplified Dissolution process that can be completed in as little as 30 days under 750 ILCS 5/452. However, this option is rarely available when divorcing an incarcerated spouse due to its strict eligibility requirements.
To qualify, couples must meet all requirements: no minor children, total marital property under $50,000 after debts, combined annual income under $60,000 with neither spouse earning over $30,000, married less than 8 years, no retirement benefits except IRAs under $10,000 combined, neither spouse owns real estate, and both spouses waive maintenance.
Most prison divorces do not meet these criteria because incarceration often involves children, property, or maintenance considerations that disqualify couples from the simplified process. Additionally, both spouses must appear together at the final hearing, which presents logistical challenges when one spouse is incarcerated.
Timeline: How Long Does a Prison Divorce Take?
| Scenario | Typical Timeline | Key Factors |
|---|---|---|
| Uncontested with cooperation | 3-6 months | Spouse signs waiver, no disputes |
| Default judgment (no response) | 4-8 months | 30-day response period, prove-up hearing scheduling |
| Contested divorce | 12-24 months | Remote hearings, document production delays |
| With minor children | 6-18 months | Parenting plan negotiations, GAL involvement |
The 6-month separation requirement under 750 ILCS 5/401(a)(2) creates an irrebuttable presumption that irreconcilable differences exist if the parties have lived separate and apart for 6 months or more. Living separate and apart does not require separate residences when one spouse is incarcerated. Courts routinely find that imprisonment itself demonstrates the parties are no longer functioning as a married couple.
Practical Considerations and Safety Planning
Divorcing an incarcerated spouse involves unique safety considerations, particularly if domestic violence contributed to the criminal conviction. Illinois offers various protective measures including orders of protection under 750 ILCS 60, victim notification programs through IDOC, and confidential address programs for survivors.
Inform the court if domestic violence occurred during your marriage. Judges can implement safety measures such as prohibiting the incarcerated spouse from contacting you directly, requiring supervised exchange of legal documents through attorneys, and notifying you of any transfer or release from custody. The IDOC Victim Services Unit provides automated notification when an offender is transferred, released, escapes, or dies.
Consider consulting with a domestic violence advocate before filing. Organizations like the Illinois Coalition Against Domestic Violence provide free legal advocacy and can connect you with attorneys experienced in high-risk divorce cases. Many counties offer specialized domestic relations courtrooms with enhanced security protocols.
FAQs: Divorcing an Incarcerated Spouse in Illinois
Can I get a divorce in Illinois if my spouse is in federal prison?
Yes, you can divorce a spouse in federal prison by following the same procedures as state prison cases. File your petition in the Illinois circuit court where you reside, then coordinate service with the federal Bureau of Prisons facility housing your spouse. Federal facilities have their own service protocols, so contact the institution's legal services department at least 2 weeks before attempting service. Illinois courts maintain jurisdiction regardless of whether your spouse is in state or federal custody.
How do I find out which prison my spouse is in?
The Illinois Department of Corrections provides an Individual in Custody Search tool at idoc.illinois.gov that displays current housing location, facility address, and contact information for any person in IDOC custody. For federal prisoners, use the Federal Bureau of Prisons Inmate Locator at bop.gov. County jail locations can be obtained by contacting the sheriff's department in the county where your spouse was sentenced.
Will my incarcerated spouse get half of everything in the divorce?
No, Illinois uses equitable distribution, not automatic 50/50 division. Courts divide property in just proportions based on twelve statutory factors under 750 ILCS 5/503, including each spouse's economic circumstances, contributions to the marital estate, and the duration of the marriage. An incarcerated spouse's reduced earning capacity typically results in the non-incarcerated spouse receiving a larger share to account for ongoing household and child-rearing responsibilities.
Can my incarcerated spouse contest the divorce?
Yes, incarceration does not eliminate legal rights to contest a divorce. Your spouse has 30 days from service to file an appearance and response. They can participate in hearings via telephone, video conference, or through legal counsel. Many incarcerated individuals qualify for court-appointed representation or assistance from legal aid organizations. However, if your spouse fails to respond within 30 days, you may proceed with a default judgment.
Do I still have to pay child support if I am incarcerated?
Yes, child support obligations continue during incarceration under Illinois law. The 2025 IMDMA amendments eliminated the automatic pause that previously stopped maintenance from accruing during imprisonment. Unpaid support becomes legally enforceable arrears collectible after release. Incarcerated parents who cannot pay must actively petition the court for modification. Courts may reduce obligations based on genuine inability to pay, but this requires filing a motion and demonstrating changed circumstances.
How long do I have to be separated before filing for divorce in Illinois?
Illinois does not require any separation period before filing for divorce. You may file immediately upon meeting the 90-day residency requirement. However, a 6-month separation period creates an irrebuttable presumption that irreconcilable differences exist under 750 ILCS 5/401. When your spouse is incarcerated, courts typically find that imprisonment itself demonstrates the parties are no longer functioning as a married couple, satisfying this requirement.
Can an incarcerated parent lose custody in Illinois?
Incarceration alone does not automatically terminate parental rights or decision-making responsibilities. Under 750 ILCS 5/602.7, courts allocate parenting time based on the child's best interests. Judges may restrict an incarcerated parent's parenting time if it would seriously endanger the child, but typically allow some form of contact such as supervised visits, video calls, or correspondence depending on facility rules and the child's needs.
What if I cannot afford a divorce lawyer?
Illinois offers multiple resources for low-income individuals divorcing an incarcerated spouse. File a fee waiver application under Illinois Supreme Court Rule 298 if your income falls below 125% of the federal poverty guidelines ($19,950 annually for a single person in 2026). Illinois Legal Aid Online at illinoislegalaid.org provides free legal information and forms. Many county bar associations operate lawyer referral services with reduced-fee consultations averaging $25-$50 for the initial meeting.
How do I get my maiden name back after divorcing an incarcerated spouse?
Include a name restoration request in your Petition for Dissolution of Marriage. Under 750 ILCS 5/413, Illinois courts routinely grant requests to restore a former name as part of the divorce judgment at no additional cost. The final decree serves as a legal document for updating your Social Security card, driver's license, and other identification. No separate name change proceeding is required when done as part of the divorce.
Can my incarcerated spouse refuse to sign divorce papers?
Yes, but their refusal does not prevent the divorce. Illinois is a no-fault state, meaning neither spouse can block a divorce by refusing to participate. If your spouse refuses to sign or fails to respond within 30 days after proper service, you may file a motion for default judgment. The court will proceed based solely on your petition and testimony, granting the divorce without your spouse's signature or cooperation.
