What should I do if my spouse is hiding income during divorce proceedings?

Courts have mechanisms specifically to address this. Your advocate can file an application seeking discovery and production of relevant financial documents — bank statements, income tax returns, property records — and the court can direct your spouse to disclose these.

If there's reason to believe specific assets or income sources are being concealed, you can point the court toward those specific leads (property records, business filings, lifestyle inconsistent with declared income) to support your request for fuller disclosure or even a forensic audit in more complex, high-value cases.

A spouse who is later found to have filed a false or deliberately incomplete affidavit of assets and income can also face consequences for that specific conduct, separate from the underlying maintenance determination. Since building this kind of case usually requires some financial investigation, it's worth discussing with your lawyer early on what specific documents or leads you already have access to.
