Section 403 of the IPC defines 'Dishonest Misappropriation of Property'. The key elements are the dishonest misappropriation or conversion of movable property for one's own use. The initial possession of the property is often innocent or neutral (e.g., finding a lost wallet), but a subsequent dishonest intention to keep it for oneself constitutes the offence. This is distinct from Theft (S.378), where the initial taking is dishonest, and Criminal Breach of Trust (S.405), where the initial possession is based on entrustment.
