This article from Lawyers.com talks about lawsuits and your small business and deals most specifically with the conditions under which you might have to consider bringing suit. Though the article says little about defending your business against a lawsuit but the inner workings of the issue are what are most important here. As the article explains, if you are in business it is likely that at some point you may be sued or bring suit at some point. The important thing to consider from both perspectives is that, as the article suggests, the higher the stakes the more likely things will end up in court. It can then be assumed that small issues are less likely to end in legal action.
