Injunction – A court order requiring that a party halt a particular activity. A court can issue an injunction at the end of a trial (a permanent injunction) or immediately, rather than wait for a trial (a preliminary injunction). A non-disclosure agreement can protect any type of information that is not generally known. However, nondisclosure agreements may also contain clauses that will protect the person receiving the information so that if they lawfully obtained the information through other sources they would not be obligated to keep the information secret. Use of non-disclosure agreements are on the rise in India and is governed by the Indian Contract Act 1872. Use of an NDA is crucial in many circumstances, such as to tie in employees who are developing patentable technology if the employer intends to apply for a patent. Non-disclosure agreements have become very important in light of India's burgeoning outsourcing industry. In India, an NDA must be stamped to be a valid enforceable document.
