High Net Worth Divorce in Illinois

Whenever a marriage ends, splitting what was built during it can be challenging, especially if spouses can’t agree on which of them should get what in the divorce. A family business, a brokerage account, a rental property, and a stock option grant each raise their own questions. Who should receive it in the divorce? How much is it worth? Should it be split, and if so, how? The answers can shape your finances for decades, so small errors can cost you a lot.

Illinois courts divide marital property “in just proportions,” according to 750 ILCS 5/503. In practice, that means a fair or equitable split, which may or may not be 50/50. In a divorce with substantial assets, that standard leaves room for disagreement over what counts as marital property, how each asset is valued, and how taxes affect the final numbers. Accurate financial information and a clear plan give you the strongest footing.

High-Asset Divorce Representation

SLG Family Law is a divorce and family law firm serving clients throughout the Chicago suburbs, with offices in Schaumburg, Naperville, Orland Park, and Rolling Meadows. Our attorneys have spent years representing spouses whose divorces involve closely held businesses, investment holdings, and real estate.

These cases often revolve around the finer details of a couple’s financial picture. When a case calls for it, we work with forensic accountants and tax professionals to trace assets and test valuations. We review any prenuptial or postnuptial agreement at the start because its terms can change how property is divided. We also keep you informed as the case moves along so that you can make wise decisions at every step. 

Many of our clients would rather keep their financial lives out of public view. We approach every high-net-worth case with that kind of discretion in mind.

Who We Serve

High-net-worth divorce clients come from many walks of life, but they often share many of the same concerns. They want to know what they could lose, what they can keep, and how to plan for life after the divorce. We regularly help people who:

• Own a successful business. Business owners often realize their company could become part of the divorce settlement, so they want to understand how to protect it. The answer often depends on when the business started and how marital money or effort helped it grow.
• Have significant investments. These clients have accumulated investment accounts, brokerage portfolios, retirement funds, or cryptocurrency and want to know how those assets will be handled. Some accounts may be partly marital and partly separate, which calls for careful tracing.
• Recently received an inheritance. They inherited money, real estate, or family property and worry their spouse may have a claim to it. Illinois treats inherited property as nonmarital, but mixing it with marital funds can weaken that protection.
• Own multiple properties. Whether it is vacation homes, rental properties, or commercial real estate, these clients want to avoid costly mistakes when dividing real estate. Appraisals, mortgages, rental income, and taxes on a future sale all factor into a fair split.
• Earn a high income. Doctors, executives, attorneys, entrepreneurs, and other high earners often worry about long-term financial obligations like spousal maintenance. At higher incomes, Illinois judges have more discretion over the amount and length of support.

What to Expect in a High-Net-Worth Divorce

Every case is different, but most high-asset divorces in Illinois move through the same core stages. Knowing them ahead of time helps you prepare and make better choices along the way.

1. Full financial disclosure. Each spouse completes Illinois’ standardized Financial Affidavit, which includes supplemental schedules for business interests, investment accounts, retirement accounts, and other property. Supporting records such as tax returns and account statements usually follow. Complete and accurate disclosure from the start protects your credibility with the court.
2. Classifying marital and nonmarital property. Under Section 503, property either spouse acquires during the marriage is presumed marital. Property owned before the marriage or received “by gift, legacy, or descent” is generally nonmarital. A spouse who claims an asset as separate must prove it with clear and convincing evidence, which often means tracing the money back to its source.
3. Valuing the assets. Illinois values property at fair market value, usually as of the date of trial unless the spouses agree on another date. A business may be valued using income, assets, or market-based methods. Forensic accountants can also spot income or assets that are hard to find, such as funds held through a company or trust.
4. Addressing dissipation. Dissipation means one spouse used marital assets for purposes unrelated to the marriage while it was breaking down. A spouse who raises this claim must file a written notice no later than 60 days before trial or 30 days after discovery closes, whichever is later.
5. Deciding maintenance. Illinois has a guideline formula for spousal maintenance, but it applies only when the couple’s combined gross annual income is less than $500,000, according to 750 ILCS 5/504. Above that level, the court weighs factors such as each spouse’s income, needs, and the standard of living during the marriage.
6. Settlement or trial. Many high-asset cases settle through negotiation or mediation once both sides have reliable numbers. If an agreement is not possible, a judge decides the open issues at trial. Throughout, the court must also consider the tax consequences of how property is divided.

While the case is pending, either spouse may ask the court for temporary orders on support, use of property, or other urgent issues.
