You prepare the tax returns for a company and you prepare a calendar year end audit for the company. They are required to audit their bank they finance with and provides them a Line of Credit. The one partner of the company personally asked our firm to perform a "forensic" analysis of the company to see if the other is been stealing money. The 2ns partner was running personal expenses through the company.

Question: What are the professional standards in tax preparation, audit and forensic services in this situation. What are the CPA's duties to the company? Did we violate any laws?
