In the United States, larceny is a common law crime involving theft. Under the common law, larceny is the trespassory asportation and taking of the tangible personal property of another with the intent to deprive him or her of it permanently. In English law, the common law offense was codified into the Larceny Act 1916. In turn, the terminology and substance was converted into theft by the Theft Act 1968.
Larceny under common law is never applied to real property (land), or services. However, in the U.S., the Model Penal Code (MPC) states that services can be the subject of theft. Wild animals (ferae naturae) are deemed to not be the property of the owner of whatever land they are found on, so takings of wild animals are also not subject to larceny.
One can only "steal" one's own property when another has a better right to possession at the relevant time. Larceny is a crime of possession, not ownership. Thus, if a vehicle is under the possession of a mechanic, and the owner takes the vehicle, he could be guilty of larceny.
In most of the United States the common law definitions of certain crimes have been modified. Quite often the general crime of theft has replaced larceny, and most related common law and statutory crimes such as embezzlement, false pretenses, robbery, and receipt of stolen property.
In the PBS kids' series, Where in the World Is Carmen Sandiego? (game show), one of Carmen's gang members was a blonde-haired girl named Patty Larceny.
