A co-defendant is an individual who is accused alongside one or more other individuals in a legal case. In criminal trials, co-defendants may be charged with the same crime or related offenses, and they often share legal representation or have separate attorneys. Their cases are typically tried together to streamline the judicial process. In a courtroom setting, co-defendants may present different defenses or strategies, which can lead to complex legal dynamics. The actions or testimonies of one co-defendant can impact the outcomes for the others, making their relationships and decisions crucial in cases involving multiple defendants, such as in cases of conspiracy or joint criminal enterprise.
