License
A voluntary agreement in which the creator or owner of something grants another permission to use it under specified terms. A license is a form of Contract: it requires consent, clear terms, and honest dealing from both sides. Violating a license's terms is Contract Breach, creating a victim who is owed Restitution. A license granted under duress or with hidden terms is invalid. A license imposed by authority rather than agreed between trade partners is regulation, not a real license.
