Kevin's firm handled setting up my will and trust recently. They took something that seemed intimidating and made it easy to understand. I've also referred a couple clients to Kevin - he's trustworthy, approachable and very fairly priced.
"I've used Kevin and his firm's services since 2011. He gave undivided attention to my cases, advised me on different options and..."

Illinois doesn't call it alimony anymore, it's "maintenance," and it's not something every divorce includes. A judge only awards it if one spouse genuinely needs financial support and the other has the ability to pay, so it's never automatic just because a marriage is ending. When maintenance is on the table, most cases with a combined income under $500,000 follow a set formula: 33.3% of the paying spouse's net income minus 25% of the receiving spouse's, with a cap so the recipient never ends up with more than 40% of the couple's combined income. How long payments last usually ties back to how long you were married, longer marriages generally mean longer support. One thing worth knowing if you're dealing with a case that involves incarceration: a 2025 change to Illinois law removed the old rule that paused maintenance while the paying spouse was locked up, so those payments now keep accruing as a debt. It's a small detail, but it's exactly the kind of thing that trips people up if they're working off outdated information.
Maintenance cases are rarely just about plugging numbers into a formula. Judges look at the full picture, income, the standard of living during the marriage, whether one spouse put a career on hold to raise kids or support the household, and more. We help you build the case for what you actually need, or push back when a request seems inflated. If you're the one who may end up paying, we make sure the numbers reflect your real financial picture, not an inflated estimate. And if your case involves a higher combined income or other factors that pull it outside the standard formula, we know how to argue that side too. Whichever side of the table you're on, our job is to make sure the outcome is grounded in your actual circumstances.
A maintenance order isn't something you want to get wrong out of the gate. It affects your monthly budget for years, and unwinding a bad agreement later is far harder than negotiating a fair one up front. We help clients gather the right financial documentation, understand how the formula applies (and when it doesn't), and think through how maintenance interacts with other parts of the divorce, like property division or child support. If circumstances change down the road, a job loss, a big raise, remarriage, we can also help you revisit an existing order. Bring us your numbers and your questions, and we'll help you see exactly where you stand.

Not necessarily. A judge has to find that maintenance is appropriate in the first place, looking at need and ability to pay, before any formula gets applied. Simply out-earning your spouse doesn't automatically mean you'll owe support.
It generally depends on how long you were married, with the length of support increasing in steps as the marriage gets longer. Marriages of 20 years or more can result in maintenance lasting as long as the marriage itself, or even indefinitely in some cases.
Yes, if there's been a substantial change in circumstances, like a significant change in either spouse's income, a job loss, or the recipient remarrying or moving in with a new partner. The court will look at the updated situation and decide whether an adjustment is warranted.
