How to Request Alimony in Illinois

You request alimony in Illinois by asking the court for it inside a divorce, legal separation, or invalidity case, either in your petition or by a separate motion. Illinois law calls this support maintenance, and the court decides in two steps: first whether an award is appropriate at all, then how much and for how long. ^[1]

Maintenance is not automatic, and asking for it the right way matters. The judge looks at a defined set of factors to decide whether you qualify, then usually applies a set formula to set the number. Where your request fits within the broader framework of Illinois spousal maintenance shapes what evidence you need and what you can realistically expect.

Who Can Request Alimony in Illinois?

Either spouse can request maintenance, regardless of gender or who filed for divorce. The right to ask does not depend on fault. Illinois decides maintenance without regard to marital misconduct, so an affair or who caused the breakup does not decide whether you receive support.

What matters is financial need and the other spouse's ability to pay, measured against the statutory factors. A stay-at-home parent, a lower-earning spouse, or a spouse who paused a career for the family are common candidates. A short marriage between two similar earners is not.

When You Can Ask for Maintenance

Timing is part of the request. You can raise maintenance at three points in a case, and many people use more than one:

• During the divorce: you can request temporary maintenance to cover living costs while the case is pending.
• At final judgment: the court sets the amount, duration, and type of maintenance as part of the final order.
• After the divorce: if maintenance was reserved or your circumstances change, you can return to court to seek or adjust an award.

How to Request Alimony in Illinois, Step by Step

The process is predictable, but the timeline depends on whether your spouse agrees and how complex your finances are. Agreed requests move quickly. Contested requests follow the full path below.

Step 1: Put the Request in Your Petition or File a Motion

You ask for maintenance in the petition that opens your divorce or legal separation, or you file a motion once the case is underway. The filing names what you want: temporary support now, maintenance in the final judgment, or both. If your case is already filed and you left maintenance out, you can still raise it before judgment.

Step 2: File Your Financial Affidavit and Supporting Documents

Every maintenance request runs on financial disclosure. Illinois requires a statewide financial affidavit backed by documents such as tax returns, pay stubs, and bank statements. ^[2] Both spouses exchange this information, and the court can hold a hearing if the sworn numbers do not match the paperwork.

Step 3: Request Temporary Maintenance If You Need Support Now

If you cannot cover basic expenses while the divorce is pending, you can ask for temporary maintenance under Illinois's temporary relief rules. Courts handle these requests on a summary basis using the financial affidavits and supporting documents, so relief can come faster than a full trial. A temporary order lasts until the final judgment is entered.

Step 4: The Court Decides Whether Maintenance Is Appropriate

Before any number is calculated, the judge makes a threshold finding on whether maintenance is appropriate at all. This decision weighs the statutory factors in your case. If the court finds an award is not appropriate, it bars maintenance no matter how long you were married.

Step 5: The Court Sets the Amount and Duration

Once maintenance is found appropriate, the court sets the amount and duration. Most cases use a statutory guideline formula. Higher-income cases and cases with prior support obligations fall outside the formula and are decided on the factors instead. The calculation section below breaks down both paths.

Step 6: The Court Enters the Order and Its Type

The judge enters a maintenance order and must state its type: fixed-term, indefinite, reviewable, or reserved. The order also spells out the payment amount and how long it lasts. That order controls going forward and can be revisited later if circumstances change.

Key Issues When Requesting Alimony in Illinois

A few issues decide most maintenance requests. Understanding them before you file is the difference between a request built on the right evidence and one that stalls.

The Two-Step Analysis

Illinois separates the question of whether you get maintenance from the question of how much. Under 750 ILCS 5/504(a), the court first decides appropriateness using a list of factors. Only after that finding does it move to the amount and duration. Your request should speak to both steps, not just the dollar figure.

Guideline vs. Non-Guideline Maintenance

The guideline formula applies when the spouses' combined gross annual income is under $500,000 and the paying spouse has no child support or maintenance obligation from a prior relationship. Above that income level, or when a prior obligation exists, the court sets a non-guideline award based on the statutory factors. Knowing which track your case is on shapes what you ask for.

The 40% Cap

Guideline maintenance carries a ceiling. The award, added to the receiving spouse's net income, cannot leave that spouse with more than 40% of the couple's combined net income. This cap can reduce a formula result, so the raw calculation is not always the final number.

Duration and the Length of the Marriage

How long maintenance lasts is tied to how long you were married. Illinois multiplies the length of the marriage by a set factor that rises with each year. For marriages of 20 years or more, the court can order maintenance for a period equal to the marriage or for an indefinite term.

Temporary Maintenance Can Reduce Final Duration

Temporary support helps you during the case, but it can carry a cost at the end. The court has discretion to credit time you received temporary maintenance against the duration of your final award. That tradeoff is worth planning for before you request temporary support.

Documents You'll Need to Request Alimony in Illinois

Preparation before filing shortens the case and strengthens your position. Gathering the following helps your attorney move efficiently from day one:

• Petition or motion: the filing that requests maintenance and states what you are asking the court to order.
• Statewide financial affidavit: the sworn financial disclosure that drives both temporary and final maintenance decisions.
• Income documentation: recent tax returns, pay stubs, and year-end statements for both spouses where available.
• Bank and account statements: records that show cash flow, savings, and monthly spending.
• A monthly budget: a realistic accounting of your living expenses and needs after separation.
• Records of career sacrifice: documentation of time out of the workforce, delayed education, or support you gave to your spouse's career.

How Alimony Is Calculated in Illinois

When the guideline formula applies, the math is defined by statute rather than left to argument. Two parts drive the result: the amount and the duration.

Amount. The annual maintenance figure is 33 1/3% of the paying spouse's net annual income minus 25% of the receiving spouse's net annual income. The 40% cap then limits the result if it would push the receiving spouse's share too high.

Duration. The length of the marriage is multiplied by a statutory factor that climbs with each year of marriage, from .20 for the shortest marriages up to .80 approaching 20 years. At 20 years or more, the court may order maintenance equal to the length of the marriage or for an indefinite term.

These numbers are the starting point, not a guarantee. The court can depart from the guidelines when it explains why in writing, and non-guideline cases skip the formula entirely.

Risks and Complications to Be Aware Of

Maintenance requests fail or backfire more often than people expect. Knowing what can go wrong is part of building a request that holds up.

Asking Without Meeting the Appropriateness Standard

If the court finds maintenance is not appropriate, it bars an award outright. A weak request wastes time and can hand your spouse leverage. An honest read of your facts before filing matters more than the size of the number you want.

Inaccurate Financial Affidavits

The financial affidavit is sworn, and Illinois takes it seriously. If a party intentionally or recklessly files an inaccurate or misleading affidavit, the court must impose penalties and sanctions, including costs and fees. Accuracy protects your credibility and your case.

Guideline Assumptions That Don't Fit Your Case

The formula assumes a fairly typical income picture. High combined income, self-employment, variable pay, or a prior support obligation can move your case off the guidelines. Treating a non-guideline case as if the formula controls leads to an unrealistic request.

The Temporary-to-Final Duration Tradeoff

Temporary maintenance solves an immediate cash problem, but the court can subtract that time from your final award. Requesting temporary support without accounting for the credit can shorten how long your final maintenance lasts.

How Long Does It Take to Get an Alimony Order in Illinois?

Timelines vary by county, conflict level, and complexity. A temporary maintenance request can be heard quickly because courts handle it summarily. A final maintenance award is set as part of the overall divorce, so it moves on the divorce's timeline.

• Temporary maintenance: often heard within weeks of the motion, since the court decides on a summary basis.
• Agreed final maintenance: typically resolved on the divorce timeline once both spouses agree on terms.
• Contested final maintenance: commonly several months or longer when income is disputed or experts are involved.
