What the accountant actually does
In a divorce, a forensic accountant reconstructs income from tax returns, bank records, and business books, and compares it with what the household actually spent. They trace whether an asset came from separate funds or marital ones, which matters when property owned before the marriage was mixed with joint money. They also look for transfers to relatives, unusual business expenses, or delayed income that may not show up on a pay stub. Their work can support a claim about hidden assets, but it can just as easily show that a suspicion was unfounded, which is useful to know too. Either result usually shortens the argument.
Retained or neutral
Some accountants are retained by one spouse through counsel, while others are appointed by the court or jointly chosen as neutrals. A retained accountant can help shape your strategy, while a neutral's report tends to carry weight because neither side picked the result. How the accountant is engaged can affect what is protected from disclosure, so the arrangement is usually set up by your lawyer rather than by you directly. The cost can be significant, and New York courts can direct the more-monied spouse to contribute toward it. Whichever route is chosen, the accountant's independence will be tested if the case is tried.
Getting them what they need
The accountant's work depends on records: several years of personal and business tax returns, bank and credit card statements, loan applications, and the business's ledgers if you can lawfully reach them. Loan applications are often revealing, since people tend to describe their income generously to a lender. Tell your lawyer what you know about how the household was funded and where money seemed to go, rather than keeping it in personal notes. In an early meeting we decide whether an accountant is needed now, later, or at all, and what a limited first engagement would look like. A narrow first assignment often answers whether a broader one is worth the cost.
