Laws vary from state to state. Successor liability laws transfer responsibility for payment of certain business debts to the new owner when a business is sold. In the majority of small business transactions, the sale will be an "asset sale," and the seller will pay liabilities and keep current assets. Unless you buy the actual Corporation, a "stock sale," you would not be responsible for liabilities, unless they are specifically agreed to in the Closing Documents. You should check for possible back taxes, liens, penalties and fines that may transfer to you upon purchase of the new business. Your CPA or Attorney, or the Closing Attorney will generally handle that task, so that you are assured you are receiving a clear title.
