Non-disclosure contract – this is a type of agreement which applies to the Business Law and Trade Law. Its purpose is to keep the information, which two parties exchange, during their business relations, confidential. Also, to avoid sharing it with any third parties. Such contracts are important because trade information is of high value. And traders should protect it from leaking eventually to competitors. For example, if you have invented a new product, then you should have such contract signed with your supplier/producer. So to avoid someone stealing your idea or to starting selling it on the market before you do so.
