When a business partner is stealing from the business, it may be incredibly difficult to detect. Business partners legally have access to business accounts, merchandise, and more. However, misappropriation of any business assets could be considered not just a violation of the partnership under civil law, but could also be criminal acts. Partners are considered fiduciaries for each other.
If you suspect that your business partner is stealing, or misappropriating assets, deciding on the correct course of action is not easy. At the first suspicion, you should contact a qualified business attorney to help guide your investigation, and advise you on whether, when, and how to contact law enforcement, and potentially how to end the partnership without ending the business.
Depending on your business, and what was stolen, how you proceed could be critical to ensuring your business's survival.
