For evidence to be admissible in court, it must generally be relevant (making a fact in the case more or less probable), reliable, and not unfairly prejudicial, confusing, or a waste of time. Key requirements include proper authentication (proving it's what it claims to be), establishing a clear chain of custody, and fitting within exceptions to rules that exclude certain types of evidence, like hearsay or character evidence. A judge acts as a "gatekeeper" to ensure these standards are met before evidence is presented to the jury.
