Permission is a license to do something, in some cases authorizing a person or entity to do an act which without such authority would have been unlawful. Permissions may be sought for a wide range of actions. For example, permission may required in the release of confidential information to a third party, such as medical records, or for the use of copyrighted material.
Permissions are often used in certain settings, such as school and rental apartments. Schools often require parental permission for students to attend field trips or participate in extracurricular activities. In the landlord-tenant relationship, tenants are often required to get a landlord's permission before subletting or assigning a lease.
