An entailment is an unusual legality that prohibits a piece of land from being sold. It was designed to protect a family’s interest in a piece of land because it could only be passed down to a member of the same family, never sold for profit. Jem describes an entailment as "a condition of having your tail in a crack," and Atticus later says that Jem’s description is surprisingly accurate.
