Understanding alimony in Illinois is critical when planning for divorce or defending against spousal support claims.
While many people assume that simply being married and having a lower income entitles them to alimony, Illinois law includes specific grounds that can disqualify a person from receiving or continuing to receive spousal maintenance.
Whether you are seeking support or facing demands for payment, knowing what circumstances prevent alimony eligibility helps you make informed decisions about your case.
This guide explains the legal grounds for disqualification under Illinois law and how courts apply these rules in Cook County and throughout the state.
What is alimony in Illinois?
Alimony in Illinois is legally referred to as “spousal maintenance” or “maintenance.” It is financial support paid by one spouse to the other during or after divorce to help the recipient maintain a reasonable standard of living.
The purpose is not to punish the payor or reward the recipient, but to address economic disparities created during the marriage.
Maintenance is not automatic. Courts evaluate multiple statutory factors including the length of the marriage, each spouse’s income and earning capacity, the standard of living established during the marriage, and contributions each party made to the other’s career or education.
Even when these factors suggest maintenance is appropriate, certain behaviors or circumstances can disqualify a spouse from receiving support.
Statutory grounds for disqualification from alimony in Illinois
Illinois law establishes clear conditions under which spousal maintenance can be denied, reduced, or terminated.
These statutory grounds apply regardless of other factors that might otherwise support an alimony award.
Remarriage of the recipient
Illinois law automatically terminates maintenance when the recipient spouse remarries. This is one of the clearest disqualifications. No court order or legal action is required—remarriage immediately ends the payor’s obligation.
If the recipient remarries and continues accepting payments without notifying the payor, they may be required to repay those amounts.
Cohabitation with another person
While remarriage automatically terminates alimony, cohabitation (living with another person in a marriage-like relationship) can also result in termination or modification.
Illinois law allows courts to terminate maintenance when the recipient “cohabitates with another person on a continuing conjugal basis.”
Courts look at multiple factors to determine whether cohabitation qualifies as “continuing” and “conjugal”: sharing a residence, financial interdependence, presenting as a couple publicly, shared household responsibilities, and the nature of the relationship.
Mere roommate arrangements do not qualify. The burden of proof falls on the party seeking termination to demonstrate that the cohabitation meets the legal standard.
Short-term marriages without economic dependence
While not an absolute disqualification, very short marriages (typically under three years) where both spouses maintained economic independence often result in no maintenance award.
Illinois courts consider the duration of the marriage as a primary factor in both amount and duration of maintenance.
If the marriage was brief and neither party sacrificed career opportunities or earning capacity for the relationship, courts may determine that maintenance is unnecessary.
Self-sufficiency and earning capacity
If the spouse seeking maintenance has sufficient property (including marital property received in the divorce) or earning capacity to meet their reasonable needs, courts may deny maintenance entirely.
This applies when the recipient can support themselves through employment, investments, or property awards from the divorce settlement.
Courts also consider “potential” earning capacity. If a spouse voluntarily remains unemployed or underemployed despite having marketable skills and work history, judges may impute income based on what they could reasonably earn.
This imputed income can disqualify them from maintenance or significantly reduce the amount awarded.
Adultery and marital misconduct (limited impact)
Illinois is a “no-fault” divorce state, meaning you do not need to prove wrongdoing to obtain a divorce. However, marital misconduct—including adultery—can still influence maintenance decisions in limited circumstances.
Under 750 ILCS 5/504, courts may consider “any other factor that the court expressly finds to be just and equitable” when determining maintenance.
Some judges consider egregious marital misconduct, particularly when it caused economic harm to the marriage (for example, if a spouse spent marital assets on an affair partner).
However, adultery alone rarely disqualifies someone from maintenance if other statutory factors support an award.
The impact of adultery varies significantly by judge and the specific facts of the case. Unlike some states that bar adulterous spouses from alimony entirely, Illinois takes a more nuanced approach.
Fraud or misrepresentation during divorce proceedings
Providing false information about income, assets, employment status, or living arrangements during divorce proceedings can result in disqualification from alimony.
If a court later discovers that a recipient obtained maintenance based on fraudulent representations, the payor can file a motion to terminate or modify the order.
Common examples include hiding employment income, falsely claiming disability or inability to work, concealing assets, or lying about cohabitation status.
Courts take fraud seriously, and proven misrepresentation can result in not only termination of maintenance but also sanctions and potential repayment of amounts already received.
Voluntary unemployment or underemployment
Courts may deny or reduce maintenance when a spouse voluntarily leaves employment or refuses to seek reasonable work without legitimate justification. This applies when someone quits a job to increase their maintenance claim or deliberately avoids employment to appear financially dependent.
However, courts distinguish between voluntary unemployment and legitimate reasons for not working, such as:
- Caring for young children when childcare costs exceed potential earnings
- Documented disability or health conditions preventing employment
- Age and length of time out of the workforce making reentry unrealistic
- Returning to school to improve future earning capacity (if reasonable)
The key question is whether the unemployment or underemployment is a strategic choice to manipulate maintenance calculations or a legitimate circumstance.
Additional grounds for termination or modification
Beyond the statutory disqualifications that prevent initial awards, certain circumstances can terminate or modify existing maintenance orders.
Death of either party
Maintenance obligations automatically terminate upon the death of either the payor or the recipient.
Unlike child support, which can create estate claims, spousal maintenance ends with death unless the divorce judgment specifically states otherwise or the parties created a contractual obligation that survives death.
Substantial change in circumstances
Illinois allows modification of maintenance when there has been a “substantial change in circumstances”.
This can work in either direction—increasing, decreasing, or terminating maintenance based on changed conditions.
Examples of substantial changes include:
- Significant income increases or decreases for either party
- Job loss or career advancement
- Retirement (particularly at normal retirement age)
- Disability or serious health changes
- Changes in the recipient’s financial needs
The party seeking modification must prove that the change is substantial, continuing (not temporary), and was not contemplated when the original order was entered.
Termination by agreement
Spouses can agree to terminate maintenance through a written agreement that the court approves.
Some couples include sunset provisions in their divorce agreements that automatically terminate maintenance after a specified period or upon certain triggering events (such as the payor’s retirement).
Once the court approves a contractual maintenance arrangement, modification may be more limited than with court-ordered maintenance, depending on how the agreement is structured.
How courts evaluate disqualification claims
When a party seeks to deny, terminate, or modify maintenance based on disqualification grounds, they must file appropriate motions with the court and provide evidence supporting their claims.
The burden of proof typically falls on the party seeking to deny or terminate maintenance.
For example, if a payor claims the recipient is cohabitating, they must present evidence demonstrating the conjugal nature and continuing status of the relationship.
Courts evaluate credibility, examine financial records, consider testimony from witnesses, and apply statutory factors to the specific facts presented.
In Cook County, these matters are heard in the Domestic Relations Division, where judges have significant experience evaluating maintenance disputes and applying Illinois law to diverse factual situations.
What happens if you are disqualified from alimony?
Disqualification from maintenance has immediate practical consequences. If you are denied maintenance in an initial divorce judgment, you typically cannot seek it later unless you can prove changed circumstances that were unforeseeable at the time of divorce.
If existing maintenance is terminated due to disqualification (such as remarriage or cohabitation), payments stop as of the termination date. In cases involving fraud or misrepresentation, courts may order repayment of maintenance already received.
For payors, successful disqualification claims eliminate ongoing financial obligations and provide closure to the financial aspects of the divorce.
For recipients, disqualification means the need to achieve financial independence through employment, property assets, or other means.
