Spousal Support Attorneys in Illinois

Leaving an unhappy marriage shouldn’t mean sacrificing your financial security. Yet for many people, that’s exactly what it feels like; they’re torn between the fear of not being able to make ends meet and the need to finally divorce. 

At SLG Family Law, we help clients find balance between emotional freedom and financial stability. With a clear understanding of Illinois spousal support laws and a commitment to protecting your long-term well-being, our spousal support attorneys guide you toward outcomes that are fair, sustainable, and grounded in respect for what you’ve contributed to your marriage.

What Is Spousal Maintenance?

Maintenance is financial assistance paid from one spouse to the other during or after divorce proceedings. Illinois courts can award it to either spouse based on fairness, and marital misconduct has no bearing on the decision. The purpose is to address income gaps between spouses so the receiving spouse can maintain a reasonable standard of living while working toward financial independence.

This system recognizes that one spouse may have given up career opportunities to manage the household or supported the other’s education and career advancement. Maintenance provides a financial bridge, giving the receiving spouse time to build job skills, finish an education, or reestablish a career.

Should You Seek Spousal Maintenance?

Spousal maintenance applies to a wide range of situations. Here are the clients we most commonly help at SLG Family Law:

• Financially Dependent Spouses. One spouse relied on the other’s income throughout the marriage and now isn’t sure how to cover everyday expenses after the divorce.
• Stay-at-Home Parents or Spouses with Limited Work History. One spouse paused or scaled back their career to care for children and now needs support as they rebuild their financial footing.
• Business Owners or Spouses with Variable Income. One spouse owns a business or earns income that fluctuates with bonuses, commissions, distributions, or profits, making maintenance calculations more complex.
• Spouses in Long-Term Marriages. After many years together, one spouse may worry about age, health, a diminished standard of living, or a long absence from the workforce.
• Spouses Who Need Support During the Divorce Process. One spouse may need temporary financial assistance while the case works through the courts and before final financial terms are settled.

If your situation fits one of these categories, or even if it doesn’t, speaking with a family law attorney can help you understand whether maintenance is an option worth pursuing.

How Do Illinois Courts Decide Whether to Award Maintenance?

Just because you depended on your spouse financially does not automatically mean a court will award spousal maintenance. Courts look at several factors to determine whether a meaningful gap exists in income or earning potential between spouses, including:

• Each spouse’s income, property, and realistic earning capacity
• Individual needs and the standard of living established during the marriage
• Any impairment to earning capacity caused by domestic duties or forgone career opportunities
• The time needed to gain education, training, or employment
• Parental responsibilities that affect one spouse’s ability to work
• The length of the marriage, along with age, health, and vocational skills
• Contributions made to the other spouse’s education, training, or career
• Tax consequences and any valid agreements between the parties

Courts weigh these factors together, giving them real flexibility to reach a result that fits the specific marriage.

How Is Spousal Maintenance Calculated?

Once a court determines that spousal maintenance is warranted, it applies a specific formula to calculate both the amount and duration of support. For couples with combined gross annual incomes under $500,000, Illinois law sets out a clear framework:

Amount Formula:

• 33.33% of the paying spouse’s net annual income
• Minus 25% of the receiving spouse’s net annual income
• The total cannot exceed 40% of both spouses’ combined net income

Duration Calculation:

The length of support is determined by multiplying the length of the marriage by a statutory percentage:

• Less than 5 years: 20% of marriage duration
• 5-6 years: 24%
• 6-7 years: 28%
• 7-8 years: 32%
• 8-9 years: 36%
• 9-10 years: 40%
• 10-11 years: 44%
• 11-12 years: 48%
• 12-13 years: 52%
• 13-14 years: 56%
• 14-15 years: 60%
• 15-16 years: 64%
• 16-17 years: 68%
• 17-18 years: 72%
• 18-19 years: 76%
• 19-20 years: 80%
• 20+ years: Indefinite term or 100% of marriage duration

For couples with combined incomes above $500,000, courts have broader discretion in setting an appropriate amount. Knowing where you fall within this framework is a good first step in understanding what support may look like in your case.

Why Let SLG Family Law Help You Maintain Financial Stability?

Spousal maintenance can shape your finances long after your divorce is finalized. Getting a fair outcome requires looking at your income, assets, lifestyle, and future needs together and building a strategy around the full picture. That’s where our approach makes a difference:

• We help you understand what you may actually receive. Our Illinois spousal support calculator applies the statutory formula to your numbers, giving you a real starting point for planning rather than a guess.
• We treat maintenance as part of your full financial picture. Support doesn’t exist on its own. We also handle property division, retirement accounts, and child support, so your settlement holds up as a whole.
• We build our advice around your specific circumstances. Illinois courts weigh many individual factors when deciding maintenance, and we take the time to understand your priorities before developing a strategy.
• We’re prepared for negotiation and for trial. Our process includes financial disclosures, temporary hearings, mediation or early neutral evaluation, discovery, pretrial preparation, and trial when it’s necessary. You’re never limited to one path forward.
• We stay with you after the divorce is final. If your ex-spouse’s income changes, or if they begin living with a new partner, we can help you pursue a modification or termination of support.

Your financial future deserves more than a formula. Let our spousal maintenance attorneys at SLG Family Law help you.
