When you have poured years into building a business, a divorce can feel particularly threatening. Determining your company’s value is a critical and often highly disputed step in dividing a high-asset estate.
A business valuation in a DuPage County divorce is the formal process used to determine your company’s value, a standard that is often legally defined as its ‘fair value’ rather than ‘fair market value.’ This process is known for being thorough, and you can expect that it will require precise financial documentation.
Here are three key things to expect during the business valuation process.
A neutral expert will conduct an intensive financial review
Illinois courts allow parties to use a single, neutral third-party expert, or each side may hire their own expert. If the parties cannot agree, the court may appoint an expert to provide a valuation. Regardless of who hires them, this expert will perform a deep dive into your company’s finances, far beyond a simple tax return.
Be prepared to provide extensive documentation, which often includes:
- Profit and loss statements
- Balance sheets and cash flow statements
- Business tax returns for the past three to five years
- Detailed lists of company assets and debts
- Loan agreements and shareholder agreements
This comprehensive review helps the appraiser form a complete picture of the business’s financial health.
The value includes more than just tangible assets
An expert will select the most appropriate method to calculate your business’s worth based on your industry and size. This is not a simple calculation. A major point of negotiation is “goodwill,” which is the intangible value of your business not tied to a physical asset.
Illinois law distinguishes between “enterprise goodwill,” which is the value tied to the business itself, and “personal goodwill,” which is the value tied directly to your personal reputation and skills. This distinction is vital and can significantly alter the final valuation.
The final report is a foundation for negotiation
At the end of the process, the expert produces a detailed report with a final valuation number. This number is not automatically binding, it is a professional opinion.
This report becomes the starting point for negotiations. If the methodology is flawed or data is incomplete, the report can be challenged.
Using the valuation to move forward
The ultimate goal of a business valuation is to provide a clear, defensible number for property division. Once that value is established, you can explore options like buying out your spouse’s share, trading other marital assets to keep the business intact, or arranging a structured sale.
Because this process is so complex and crucial to your financial future, it is important to have clear guidance. Consider speaking with an experienced family law attorney to understand how to best protect your interests.
