Dedication, in property law means donation of land or creation of an easement for public use. It may be expressed or implied. An express dedication of property to public use is made by a direct appropriation of it to such use. A dedication of property to public or pious uses may be implied or inferred from the acts of the owner. For example, permission to use a street without bar or impediment for a long time is evidence from which a dedication to the public may be inferred.
