How can income be calculated in a divorce case when a spouse refuses to produce documentation or is suspected of concealing sources of income? One way is through the Net Worth Method of Proof, which is used to analyze income and assets when detailed documentation is not available, either because the opposing spouse is obstructing efforts to get data and documents, or because data and documents are legitimately not available.
This method of determining income is used by the federal government in criminal income tax cases. Because it is accepted in federal criminal cases, family courts often will accept this as a reliable method for calculating income.
A detailed analysis of expenditures is performed using any documentation available. Each expenditure for the period under review is captured from bank, brokerage, and credit card statements, and each item is categorized so that totals can be accumulated for the period under analysis.
