Legal Process Outsourcing is a significant market advantage for legal departments, compliance departments, and law firms. The advantages of the interaction between internal and external legal advice are clear. The company lawyer is familiar with the company's internal structures and processes, but the external lawyer deals with legal issues from a distance. The legal department of the company acts as a kind of filter. The corporate lawyers decide with management if they can efficiently handle the legal problems themselves with their legal knowledge or give the case to a specialist. The close coordination of the legal department with external legal advice ensures an efficient explanation. This saves the company personnel costs and resources. Long-term collaborations allow the lawyer to be better acquainted with the specific way of thinking and structure of the company. The relationship between the company lawyer and the special skills of an outsourced lawyer yield high-quality results.
