Avoiding Seven Costly Divorce Mistakes in Chicago: A Legal Guide

By Nottage and Ward on December 10, 2025

Divorce is never easy, but a bad decision can make things a lot worse. Many people try to take shortcuts, believing that a DIY approach will save them time and money. Unfortunately, this can lead to costly consequences.

The Chicago divorce attorneys at Nottage and Ward, LLP have been helping professionals, business owners, and high-net-worth individuals navigate difficult divorce proceedings for years. We’ve put together this helpful guide on pitfalls to avoid based on what we’ve learned.

Underestimating the Complexity of a DIY Divorce in Illinois

DIY divorce in Illinois may sound appealing for couples hoping to split amicably and save money. But even when both parties are cooperative, important legal issues can be overlooked. You’ll want to be particularly cautious when a divorce involves children, significant assets, or long-term support obligations.

Common DIY divorce pitfalls include:

• Failing to file correct documents with the court
• Omitting mandatory disclosures under Illinois Supreme Court Rule 213
• Overlooking tax implications of asset division
• Neglecting retirement account transfers that require Qualified Domestic Relations Orders (QDROs)

It’s important to remember that Illinois is an equitable distribution state. That means the division of property is based on fairness. It isn’t an automatic 50/50 split like you will find in a lot of other states. Without experienced legal guidance, you risk walking away from the table with far less than you’re entitled to receive.

Asset Valuation Errors

Proper divorce asset valuation is essential for determining an equitable division of property. Illinois law requires full and fair valuation of marital assets. This includes everything from real estate and business interests to retirement accounts and stock options.

Common valuation mistakes include:

• Using outdated or book value for real estate and businesses
• Ignoring hidden assets or non-liquid investments
• Failing to bring in valuation experts when needed

Divorce lawyers work with forensic accountants and financial professionals to ensure your marital estate is accurately valued.

Making Incomplete Financial Disclosures

Illinois courts require full and honest financial disclosure in divorce proceedings. Hiding assets, underreporting income, or failing to list liabilities can lead to serious legal consequences, including court reversal of settlements.

Under Illinois Supreme Court Rule 13.3.1, parties are obligated to provide comprehensive financial affidavits, including:

• Income statements
• Tax returns
• Bank and investment account statements
• Business ownership documents

Be transparent from the start. Ensure your financial disclosure is thorough and accurate, whether you’re initiating or responding to a divorce filing.

Overlooking Tax Consequences

Taxes can significantly affect the true value of a divorce settlement. In Illinois, the tax consequences of divorce can surprise people, particularly when it comes to property transfers, spousal support, and retirement assets. Before finalizing any settlement, consult with a tax professional to forecast short-term and long-term tax liabilities associated with the proposed terms.

Tax-Related Oversights that could cost you money:

• Not understanding the taxable vs. non-taxable nature of maintenance payments post-2019 (under the Tax Cuts and Jobs Act)
• Failing to consider capital gains taxes on real estate or investment accounts
• Overlooking the tax burden of cashing out retirement funds prematurely

The Allocation of Parental Responsibility

Illinois law does not use the term custody. Instead, it refers to the allocation of parental responsibilities and parenting time. But regardless of the terminology, these types of disputes can be challenging.

Common mistakes include:

• Using parenting time as leverage in negotiations
• Failing to create a parenting plan that reflects the child’s best interests
• Ignoring how the court evaluates stability, involvement, and logistical concerns

Illinois courts prioritize the child’s best interests, which includes these considerations:

• The child’s wishes (if mature enough)
• The mental and physical health of all parties
• Each parent’s willingness to facilitate a positive relationship with the other

Misunderstanding Spousal and Child Support Obligations

Illinois follows specific statutory guidelines to calculate both spousal maintenance and child support. But many people misunderstand how these formulas work, or they assume the obligations are temporary when they may not be.

Mistakes to Avoid:

• Agreeing to pay (or accept) support without understanding the duration or modifiability
• Failing to consider future income changes, job loss, or retirement
• Believing verbal agreements will hold up in court

Child support is determined through the income shares model, which considers both parents’ earnings and the amount of parenting time. It’s important to know your rights and obligations under Illinois law and make sure all agreements are court-approved and clearly documented. Illinois maintenance calculations are based on combined gross income and length of marriage.

Letting Emotions Drive Legal Decisions

Divorce can stir up intense feelings, such as anger, betrayal, guilt, and sadness. While valid, these emotions often lead to irrational or self-defeating decisions, such as:

• Refusing to negotiate out of spite
• Fighting over low-value items to “win”
• Rushing into settlement to “get it over with”

These choices can prolong litigation, increase legal costs, and lead to outcomes that don’t reflect your long-term needs. Work with a legal team that balances sensitivity with strength. At Nottage and Ward, LLP, we provide the support you need while fiercely protecting your interests.
