What Makes a High Asset Divorce More Complicated?

 Posted on May 13, 2026 in High Asset Divorce

Every divorce has a complex array of marital assets that must be divided between the spouses, but high asset divorces take that complexity to a different level. People going through high-asset divorces often need to work with multiple financial professionals, such as appraisers and forensic accountants. These professionals are often worth the expense because a mistake in a high-asset divorce could cost you a significant amount of money.

Four Reasons Why High-Asset Divorces Tend To Be More Complicated in 2026

No two divorces are exactly alike. However, there are some common considerations for high-asset divorces.

Tracking Down All of Your Assets

A high-asset divorce often has a variety of properties, such as real estate, businesses, investments, and collectibles. The properties may be spread out into accounts and locations in different states or countries. You need to be thorough in searching for marital properties so they are all accounted for in the divorce. For some people, there is a possibility that one spouse may be hiding assets.

This process can take time, but it is important. Bank statements, tax returns, business records, loan applications, and account records may all give clues about property you may not know about. Careful review can help reveal the full financial picture before decisions are made.

Appraising All of Your Assets

Besides identifying your marital assets, it is also important to determine the value of the assets. You may need an appraiser with a specialized area of knowledge for some properties in a high-asset divorce. For instance, a fine art appraiser will give you the most accurate valuation of an art collection. Other properties, such as a business, may require extensive research to determine their true values.

The value of an asset is not always clear from a simple statement or estimate. A business may look profitable but carry hidden debt. Real estate may be worth more or less than expected based on the market. Investments may change in value over time. A fair appraisal can help prevent one spouse from receiving more than they should or less than they deserve.

Greater Need for Spousal Support

If one spouse makes a majority of the income in a high-asset marriage, the other spouse will be more reliant on receiving spousal maintenance after a divorce. The recipient spouse can reasonably expect to maintain a similar living standard following the divorce, which may not be possible on their own. The amount of maintenance that the recipient needs may be more than what the payor wants, which can make negotiations difficult.

The court may look at the length of the marriage, each spouse’s income, each spouse’s needs, and the lifestyle they had during the marriage. A spouse who left work to raise children or support the other spouse’s career may need time and support to become financially independent. These facts can have a major effect on maintenance discussions.

Higher Chance of Litigation

There can be millions of dollars at stake in a high-asset divorce, which neither party wants to give up. Your spouse may fight you on the value of the assets and how they should be divided. If you cannot agree on your own, you may need to take your dispute to court, where a judge will decide how the divorce agreement should be constructed.

Litigation may also become more likely when one spouse does not provide complete financial information. Disputes over business ownership, hidden assets, taxes, and support can make settlement harder. Going to court can take more time and cost more money, but it may be necessary when a fair agreement cannot be reached. Strong preparation can help protect your rights if the case must go before a judge.

Timeline for a High-Asset Divorce in Illinois

A high asset divorce in Illinois can take longer than a simpler divorce. The timeline depends on the amount of property, the level of conflict, and how much information each spouse provides. Depending on your situation, a high-asset divorce could go on for months or upwards of a year.

First, one spouse files the divorce petition. After that, both spouses usually exchange financial records. This step can take time when the marital estate includes businesses, real estate, retirement accounts, investments, or property in other states. Each asset must be found, reviewed, and valued.

Illinois courts divide marital property in just proportions, not always in an equal split (750 ILCS 5/503). If both spouses agree on the major issues, the case may move toward settlement. If they do not, the court may need hearings, appraisals, and testimony before a final judgment is entered.

Can Mediation Simplify a High-Net-Worth Divorce in Illinois?

Mediation can help simplify a high-net-worth divorce, but only when both spouses take the process seriously. In mediation, the spouses work with a neutral mediator instead of fighting over every issue in court. This can save time, reduce stress, and keep more control in the hands of the spouses.

Mediation may be useful for dividing business interests, choosing how to handle the marital home, or setting a support plan. Still, mediation does not work well if one spouse hides money or refuses to share records. A high-asset divorce often needs careful review before any agreement is signed. 

Each spouse should understand the value of the property, the tax issues, and the long-term effect of the settlement. When both sides are honest and prepared, mediation can make the divorce less bitter and more practical.
