Last year the competition in the market of legal services in Ukraine exploded. Primarily this is due to the crisis in our country and sharply reduced financial capacity of potential clients of law firms. Now has this situation where the customer can dictate terms of law, not vice versa, as often happened before. In this regard, law firms now try not to miss any client. Along with competition in the legal market companies are also cooperating with each other. Such interaction is important, based on mutual benefit and can not bring small profits. In turn, providing legal services that require the involvement of another law firm makes it possible not to lose important customers and provide a full range of skilled services.
