Hearsay is a legal term referring to the use of out of court statements as evidence.
Unless one of the many exceptions applies, hearsay is not allowed as evidence in the United States. Hearsay is the legal term that describes statements made outside of court or other judicial proceedings
In England and Wales, hearsay is generally admissible in civil proceedings but is only admissible in criminal proceedings if it falls within a statutory or common law exception, all of the parties to the proceedings agree, or the court is satisfied that it is in the interests of justice that the evidence is admissible. History of the rule The rules of hearsay began to form properly in the late seventeenth century and had become fully established by the early nineteenth century 
Hong Kong's law of hearsay is modeled on the UK law. Since 1 July 1997, English cases are merely persuasive and not binding on Hong Kong courts, but in practice they are usually followed. The situation for civil cases is covered by ss 46-55B of the Evidence Ordinance, that Ordinance also covers certain exceptions in criminal cases, supplementing the common law.
New Zealand law of hearsay is similar to that of the UK. The Evidence Act 1908 is slowly being replaced by the Evidence Act 2006.
