Spousal maintenance, often referred to as alimony, is one of the most financially significant and frequently contested aspects of divorce in Illinois. While some people expect a straightforward formula, the reality is more complex. Illinois law provides guidelines, but courts retain discretion in how those guidelines are applied.
The purpose of maintenance is to reduce unfair financial disparity between spouses after divorce. This is particularly important in marriages where one spouse earned significantly more income or where one spouse sacrificed career opportunities to support the household.
Understanding how maintenance is calculated, when courts deviate from guidelines, and what factors influence both amount and duration is critical when preparing for divorce.
What Is Spousal Maintenance in Illinois
Spousal maintenance is financial support paid from one spouse to the other either during or after a divorce. It is designed to allow the receiving spouse to maintain a reasonable standard of living and, in many cases, transition toward financial independence.
Illinois recognizes several forms of maintenance, including:
- Temporary maintenance while the divorce is pending
- Fixed term maintenance for a defined period
- Reviewable maintenance that may be extended or modified
- Indefinite maintenance, typically in long term marriages
The structure of maintenance depends heavily on the facts of the case, particularly the length of the marriage and the financial positions of both parties.
How the Illinois Maintenance Formula Works
Illinois uses a statutory formula in many cases to determine maintenance. The guideline calculation is:
- 33.33 percent of the paying spouse’s net income
- Minus 25 percent of the receiving spouse’s net income
However, there is an important limitation. The total maintenance awarded cannot result in the receiving spouse having more than 40 percent of the combined net income of both parties.
While this formula appears straightforward, disputes often arise over what qualifies as “net income.” Issues may include:
- Bonuses, commissions, and irregular income
- Self-employment earnings and business deductions
- Deferred compensation or stock-based income
Because these factors can significantly affect the calculation, the formula is often just the starting point rather than the final answer.
When Courts Do Not Follow the Formula
Illinois courts are not required to apply the guideline formula in every case. Judges may deviate when applying the formula would produce an unfair or impractical result.
Factors that commonly influence deviation include:
- A significant difference in earning potential between spouses
- One spouse leaving the workforce to raise children
- Health issues that limit a spouse’s ability to work
- High income households where the formula may not reflect actual lifestyle
For example, in a case where one spouse has a high income with substantial bonuses, the court may determine that a strict formula does not accurately capture the financial reality of the marriage.
How Courts Determine the Duration of Maintenance
The length of time maintenance is paid is often just as important as the amount. Illinois provides guideline durations based on the length of the marriage, expressed as a percentage.
However, courts still retain discretion, particularly in longer marriages.
Key considerations include:
- Whether the receiving spouse can realistically become self-supporting
- The time needed for education or job training
- The standard of living established during the marriage
In marriages lasting 20 years or more, courts may award maintenance for a period equal to the length of the marriage or on an indefinite basis. In these situations, the focus often shifts from temporary support to long term financial fairness.
Temporary Maintenance During Divorce Proceedings
Temporary maintenance may be awarded early in the case to help ensure financial stability while the divorce is ongoing.
This type of support is intended to:
- Cover basic living expenses
- Prevent one party from being financially disadvantaged during litigation
- Allow both parties to participate meaningfully in the legal process
Because temporary orders are often based on limited information, they can sometimes be adjusted as more financial details become available.
The Relationship Between Maintenance and Property Division
Maintenance and property division are closely connected in Illinois divorce cases. Courts look at the overall financial outcome rather than treating each issue separately.
For example:
- A spouse receiving a larger share of assets may receive reduced maintenance
- A spouse with limited access to liquid assets may require greater support
In some cases, parties may negotiate a tradeoff, such as accepting a larger portion of property in exchange for reduced or waived maintenance. These decisions can have long-term financial implications and should be evaluated carefully.
Common Mistakes That Impact Maintenance Outcomes
There are several common mistakes that can affect how maintenance is awarded:
- Underestimating or misreporting income
- Failing to account for non-salary compensation
- Assuming the guideline formula will automatically apply
- Overlooking future earning capacity
In particular, disputes often arise when one spouse is believed to be underemployed or intentionally earning less. Courts may impute income in these situations, which can significantly change the outcome.
Can Maintenance Be Modified After Divorce
In many cases, maintenance can be modified if there is a substantial change in circumstances.
Examples include:
- A significant increase or decrease in income
- Job loss or career changes
- Changes in health or financial need
However, some maintenance agreements are structured as non modifiable. This means the terms cannot be changed regardless of future circumstances, making it important to fully understand the agreement before it is finalized.
When Does Maintenance End
Maintenance may terminate under several conditions:
- The expiration of the maintenance term
- The remarriage of the receiving spouse
- Cohabitation in a marriage like relationship
- The death of either party
Each of these scenarios can have important legal implications, particularly when disputes arise over whether cohabitation meets the legal standard.

Speak With a Divorce Attorney
Spousal maintenance decisions can have long term financial consequences that extend well beyond the divorce itself.
