What kind of problem it is
The rules that apply depend heavily on the type of problem. Unauthorized electronic transfers from a consumer account are covered by federal rules that protect the customer, and how quickly you report the problem affects how much of the loss you can be made to bear. A payment you were tricked into sending yourself is generally treated differently, and recovery often depends on the bank's policies and the circumstances. Business accounts, wire transfers, and checks are governed largely by the Uniform Commercial Code and the account agreement, which may place more of the risk on the customer. Account closures and freezes often trace back to the bank's own compliance obligations, and banks may be limited in what they can tell you about the reasons.
Report quickly and keep a record
Notify the bank in writing as soon as you spot a problem, and keep copies of what you send along with the dates. Do not wait to see whether the issue resolves itself, because notice periods in the law and in account agreements can be short, and missing them can shift losses to you. Gather statements, the account agreement and any updates to it, transaction confirmations, and all correspondence, including chat logs and the names of representatives you spoke with. If fraud is involved, a police report or a report to the FBI's internet crime center may also help. Many account agreements contain arbitration clauses and limits on class claims, so the agreement determines much of the path forward.
Where the dispute can go
Many banking disputes are resolved through the bank's internal process once the issue is presented clearly with supporting documents. If that does not work, a complaint to the bank's regulator, such as the New York Department of Financial Services for state-chartered institutions or the relevant federal supervisor, can prompt a response, though regulators do not act as your lawyer. Beyond that, the path may be arbitration or court, depending on the agreement and the amount involved. In our first meeting we sort out which rules apply, what deadlines are running, and whether a demand letter, a regulatory complaint, or a formal claim makes sense. For businesses, we also look at whether a loan or credit relationship is affected and how to protect operations while the dispute continues.
