Understanding Temporary and Permanent Spousal Maintenance in Illinois

When you go through a divorce in Illinois, questions about money tend to move quickly to the front of your mind. If you relied on your spouse’s income during the marriage, you may worry about how you will cover your bills on your own. If you were the higher earner, you may be concerned about how much support you will have to pay and for how long. These concerns usually center around spousal maintenance, previously called alimony.

Illinois law has a detailed framework for when maintenance is appropriate, how it is calculated, how long it lasts, and what responsibilities each spouse has. Understanding these rules helps you make realistic plans and decide whether you should speak with an Illinois family law attorney.

This article walks you through temporary and permanent spousal maintenance, the statutory formulas, how the length of your marriage matters, and your obligation to work toward financial independence while receiving support.

What Spousal Maintenance Means

Spousal maintenance is controlled by 750 ILCS 5/504 of the Illinois Marriage and Dissolution of Marriage Act. The core idea behind maintenance is fairness. The law recognizes that marriage often changes each spouse’s earning capacity and financial expectations. One of you may have:

• Left the workforce or turned down promotions to care for children

• Worked part-time to support the household while the other advanced a career

• Relied on the other spouse’s income for most or all expenses

Maintenance is meant to soften the financial shock when the marriage ends, not to punish either spouse. It helps the economically weaker spouse transition toward independence and, in some cases, supports them long term when independence is not realistic.

Not every divorce involves maintenance. The court must first decide whether maintenance is appropriate in your situation. If so, it then looks at how much and how long.

Temporary Spousal Maintenance During the Divorce Process

Temporary spousal maintenance is support paid while the divorce case is still pending. Divorce is rarely instant. It may take months or longer to resolve property division, custody, and support. During that time, one spouse can be left without access to enough money for everyday expenses.

Temporary maintenance is designed to cover reasonable living costs during the case. The court looks at:

• Each spouse’s current income and necessary expenses

• Access to funds such as savings or bonuses

• Who has been paying which bills during the marriage

Unlike long-term maintenance, the statutory formula does not control temporary maintenance. Instead, the judge uses discretion to decide what is fair in the short term. The focus is on stability and making sure both sides can reasonably participate in the process.

Temporary maintenance automatically ends when your final divorce judgment is entered. At that point, the court either awards post-judgment maintenance or denies it, based on a more detailed analysis under the statute.

How Illinois Courts Decide Whether Long-Term Maintenance Is Appropriate

Once your divorce is finalized, the court turns to whether ongoing maintenance should be ordered. This is where 750 ILCS 5/504(a) comes into play. The statute lists a series of factors that the judge must consider. No single factor is decisive; the court looks at the whole picture.

Key factors include:

• Each spouse’s income and property, including what each receives in the divorce

• Each spouse’s financial needs and reasonable monthly expenses

• Present and future earning capacity of both spouses

• Whether one spouse’s career or education was limited because of time spent as a homemaker or caregiver

• The standard of living during the marriage

• The duration of the marriage

• The age and physical and emotional condition of both spouses

The court also considers how long it would take the lower-earning spouse to acquire education, training, or job skills to become self-supporting. If there is a valid prenuptial or postnuptial agreement that addresses maintenance, the court will review and apply it if it is enforceable.

In plain terms, the judge asks: Is it fair and reasonable to require one spouse to support the other, and if so, to what extent and for how long?

The Statutory Formula for How Much Maintenance You May Pay or Receive

If the court decides that maintenance is appropriate, it usually turns to the statutory formula in 750 ILCS 5/504(b-1) to determine the amount. The guidelines apply when:

• Your combined gross annual income is under $500,000, and

• Neither spouse has certain multiple prior child support or maintenance obligations

When the guidelines apply, the basic amount formula is:

Maintenance = 33⅓% of the payor’s net annual income − 25% of the payee’s net annual income

There is an important cap: the receiving spouse’s net income, including maintenance, cannot be more than 40% of the spouses’ combined net income. This prevents an award that would result in the receiving spouse ending up with more net income than the paying spouse in a way the law considers unfair.

Judges must start with this formula. However, they can deviate from it if they provide a written explanation. For example, unusual medical expenses, special needs of children, or other unique circumstances may justify going above or below the guideline amount.

How Illinois Determines the Duration of Maintenance

The amount is only half the story. The next question is: How long does maintenance last? Illinois also uses a statutory schedule for duration under 750 ILCS 5/504(b-1)(1)(B). The duration is tied to the length of your marriage.

In general:

• Shorter marriages lead to shorter maintenance periods

• Medium-length marriages lead to maintenance lasting a fraction of the marriage length

• Very long marriages can lead to maintenance that lasts as long as the marriage or even indefinitely

The statute uses multipliers that increase with each additional year of marriage. For marriages under 20 years, the court multiplies the number of years by a percentage to get a maintenance duration. For marriages of 20 years or more, the court may order maintenance for a period equal to the length of the marriage or award indefinite maintenance.

While the multipliers give structure, the judge still has discretion to adjust if the facts of your case strongly support a different outcome.

When Permanent or Indefinite Maintenance May Be Awarded

Permanent or indefinite maintenance is not automatic, even after a long marriage. Still, Illinois courts are more likely to consider it when:

• The marriage lasted at least 20 years

• The receiving spouse is older and has limited realistic job prospects

• There are serious health issues or disabilities that prevent full-time work

In these cases, expecting the receiving spouse to become fully self-supporting may not be reasonable. Long-term or indefinite maintenance helps address that reality.

Even so, “permanent” does not always mean “unchangeable.” Under Illinois law, maintenance can often be modified or terminated if a substantial change in circumstances occurs, which might include retirement, a major income change, or significant improvements in the receiving spouse’s financial situation.

Your Obligation to Work Toward Financial Independence

Maintenance is not meant to be a permanent financial crutch for a spouse who is capable of working. If you receive maintenance, the law expects you to make good-faith efforts to support yourself over time. Courts often refer to this concept as rehabilitative or reviewable maintenance.

As a receiving spouse, you are generally expected to:

• Look for appropriate employment or increase your hours if you are part-time

• Pursue education, training, or certifications that improve your job prospects

• Avoid intentionally remaining unemployed or underemployed merely to keep receiving support

If the paying spouse believes you are not making reasonable efforts, they may ask the court to review and possibly reduce or terminate maintenance. Judges look closely at whether you are genuinely trying to become self-supporting, taking into account your age, health, prior work history, and the practicality of returning to the workforce.

On the other side, a paying spouse cannot simply quit a job, cut hours without justification, or hide income to avoid supporting you. Courts can “impute” income—basically, treat you as earning what you reasonably should be earning—if they believe someone is trying to manipulate the system.

Modifying or Terminating Maintenance in Illinois

Life rarely stays the same after divorce. Jobs change, health changes, and new relationships form. Illinois law recognizes this and allows maintenance to be modified or terminated when there is a substantial change in circumstances.

Common reasons for modification include:

• A significant increase or decrease in either spouse’s income

• Serious illness or disability affecting the ability to work

• Retirement at a reasonable retirement age

• The receiving spouse becoming self-supporting or substantially more secure

Maintenance can also end automatically when certain events occur. Under Illinois law, maintenance terminates if:

• The receiving spouse remarries

• The receiving spouse begins cohabiting with another person on a resident, continuing, conjugal basis

• Either spouse dies

If cohabitation is suspected, the paying spouse can file a petition asking the court to investigate and terminate maintenance if the legal standard is met.

Why Legal Guidance Matters in an Illinois Maintenance Case

Although Illinois statutes provide formulas and factors, maintenance decisions are rarely simple. Courts have discretion, and the details of your life matter a great deal. The way your income is calculated, how your net income is defined, the nature of your employment, your health, your childcare responsibilities, and your long-term plans all affect the outcome.

Because of this, it is often in your best interest to talk with a family law attorney who understands:

• How judges in your county tend to apply the maintenance statute

• When it makes sense to argue for a deviation from the formula

• How to present evidence of your financial needs or your inability to work

• How to structure settlements that are realistic and enforceable

An attorney can also help you plan for the future. For example, if you are receiving rehabilitative maintenance, you may want to know how the court will view your job efforts at a later review date. If you are paying maintenance, you may want to understand how retirement or a job change might affect your obligation.
