Types of High Net Worth Divorce Cases We Handle in Deerfield
Not every high net worth divorce looks the same. Our Deerfield divorce attorneys handle the full range of asset types and financial structures that appear in these cases.
- Business Owner Divorces: Closely held businesses often represent the single largest asset in a marriage. We work with valuation experts to determine fair market value, distinguish marital from non-marital contributions, and structure a resolution that does not force the liquidation of a functioning company.
- Executive and Professional Divorces: Executive compensation packages involve base salary, bonuses, restricted stock units, stock options, deferred compensation, and retirement benefits. Dividing these fairly requires understanding how each piece vests and taxes.
- Investment Portfolio and Real Estate Division: Substantial investment accounts and real estate holdings call for careful division of property that accounts for tax basis, liquidity, and market conditions.
- Cases Involving Trusts and Inheritance: Illinois generally treats inheritance and gifts as non-marital property, but the analysis gets complicated when those assets have been commingled with marital funds or used to benefit the marriage.
- Hidden Asset Cases: In some contested divorces, one spouse tries to conceal income or move assets before filing. We know the signs, and we know the forensic tools available to bring the full picture to light.
- Prenuptial and Postnuptial Agreement Enforcement: When a prenuptial or postnuptial agreement is in place, the case often turns on whether that agreement is enforceable under Illinois law and what it actually covers.
- High-Asset Maintenance Disputes: In marriages with substantial income disparities, maintenance becomes a central issue. We build the financial case carefully to support the right outcome for our client.
- High-Conflict Custody with Financial Issues: When custody and complex finances both sit on the table, the case needs attorneys who can handle both dimensions simultaneously without letting one undermine the other.
Illinois Legal Requirements for High Net Worth Divorce
Illinois family law, primarily the Illinois Marriage and Dissolution of Marriage Act, governs every divorce filed in Deerfield, regardless of the size of the marital estate.
Residency. At least one spouse must have been an Illinois resident for 90 days before the final judgment is entered. For Lake County filings, courts enforce this requirement strictly.
Grounds. Illinois is a no-fault state. Irreconcilable differences are the only grounds for divorce. A six-month period of living separate and apart creates an irrebuttable presumption that those differences exist.
Equitable Distribution. Illinois divides marital property in “just proportions” rather than down the middle. Courts consider statutory factors including the length of the marriage, each spouse’s contributions to the marital estate, each spouse’s economic circumstances, and any dissipation of assets. In high net worth cases, the equitable distribution analysis often becomes the central battleground.
Marital vs. Non-Marital Property. Property acquired during the marriage is generally marital. Property owned before the marriage, or received during the marriage by gift or inheritance, is generally non-marital. Commingling and transmutation can change this classification, and large estates often involve years of complex transactions that require careful tracing.
Maintenance. Illinois applies statutory guidelines to calculate maintenance in most cases, but courts retain discretion to deviate when the facts warrant. In high-income cases, maintenance awards can depart substantially from the guideline formula.
Child Support. Illinois uses the income-shares model for child support, with guidelines administered by the Illinois Department of Healthcare and Family Services. When parental income is substantial, courts may deviate from guideline figures to reach an appropriate result.
Important Aspects of a Deerfield High Net Worth Divorce Case
These cases require careful preparation. The following elements tend to determine how a complex divorce unfolds.
Business Valuation
When a marriage includes a closely held business, the valuation of that business often drives the entire case. Valuation experts use multiple approaches: income, market, and asset. Each approach produces different numbers. The choice of approach, and the inputs used, can shift the value by millions. We work with seasoned valuation experts and prepare them to defend their conclusions under cross-examination.
Asset Tracing
Marriages that last decades involve countless financial transactions. Non-marital funds get deposited into joint accounts. Gifts get commingled with marital money. Premarital assets get sold and reinvested. Tracing these flows accurately often determines how the property is divided. Our attorneys have handled complex tracing analyses on estates with substantial premarital and inherited wealth.
Executive Compensation
Stock options, restricted stock units, deferred compensation, and carried interests each require specific analysis. Some portions may be marital and some non-marital, depending on when they were granted and when they vest. Getting this right requires attorneys who understand the structures, not just the numbers.
Tax Consequences
Divorce carries significant tax consequences at every level. The transfer of retirement accounts, the sale of a marital home, the division of investment accounts, and the treatment of maintenance all affect the ultimate value of what each spouse receives. We analyze these consequences alongside our financial experts so the agreement reflects after-tax reality.
Protection Against Common Mistakes
High net worth divorces have their own set of pitfalls. Moving money before filing. Making large purchases during the case. Ignoring digital assets and cryptocurrency. Failing to preserve records. We help clients avoid common mistakes and position the case for the best possible outcome from day one.
Privacy and Public Records
Divorce filings are generally public records in Illinois. For clients concerned about the public disclosure of financial information or business details, we pursue strategies that protect privacy where possible, including mediation, collaborative divorce, and protective orders for sensitive financial records.
