In law, a witness is someone who, either voluntarily or under compulsion, provides testimonial evidence, either oral or written, of what they know or claim to know.
A deposition in the law of the United States, or examination for discovery in the law of Canada, involves the taking of sworn, out-of-court oral testimony of a witness that may be reduced to a written transcript for later use in court or for discovery purposes. Depositions are commonly used in litigation in the United States and Canada. They are almost always conducted outside court by the lawyers themselves, with no judge present to supervise the examination.
In a legal dispute, one party has the burden of proof to show that they are correct, while the other party has no such burden and is presumed to be correct. The burden of proof requires a party to produce evidence to establish the truth of facts needed to satisfy all the required legal elements of the dispute.

The right to silence is a legal principle which guarantees any individual the right to refuse to answer questions from law enforcement officers or court officials. It is a legal right recognized, explicitly or by convention, in many of the world's legal systems.
Circumstantial evidence is evidence that relies on an inference to connect it to a conclusion of fact—such as a fingerprint at the scene of a crime. By contrast, direct evidence supports the truth of an assertion directly—i.e., without need for any additional evidence or inference.
The presumption of innocence is a legal principle that every person accused of any crime is considered innocent until proven guilty. Under the presumption of innocence, the legal burden of proof is thus on the prosecution, which must present compelling evidence to the trier of fact. If the prosecution does not prove the charges true, then the person is acquitted of the charges. The prosecution must in most cases prove that the accused is guilty beyond a reasonable doubt. If reasonable doubt remains, the accused must be acquitted. The opposite system is a presumption of guilt.
Discovery, in the law of common law jurisdictions, is a phase of pretrial procedure in a lawsuit in which each party, through the law of civil procedure, can obtain evidence from other parties. This is by means of methods of discovery such as interrogatories, requests for production of documents, requests for admissions and depositions. Discovery can be obtained from nonparties using subpoenas. When a discovery request is objected to, the requesting party may seek the assistance of the court by filing a motion to compel discovery. Conversely, a party or nonparty resisting discovery can seek the assistance of the court by filing a motion for a protective order.

In criminal law, self-incrimination is the act of making a statement that exposes oneself to an accusation of criminal liability or prosecution. Self-incrimination can occur either directly or indirectly: directly, by means of interrogation where information of a self-incriminatory nature is disclosed; or indirectly, when information of a self-incriminatory nature is disclosed voluntarily without pressure from another person.
The law of evidence, also known as the rules of evidence, encompasses the rules and legal principles that govern the proof of facts in a legal proceeding. These rules determine what evidence must or must not be considered by the trier of fact in reaching its decision. The trier of fact is a judge in bench trials, or the jury in any cases involving a jury. The law of evidence is also concerned with the quantum (amount), quality, and type of proof needed to prevail in litigation. The rules vary depending upon whether the venue is a criminal court, civil court, or family court, and they vary by jurisdiction.
The term "smoking gun" is a reference to an object or fact that serves as conclusive evidence of a crime or similar act, just short of being caught in flagrante delicto. "Smoking gun" refers to the strongest kind of circumstantial evidence, as opposed to direct evidence. Direct evidence would be eyewitness testimony of someone who saw an actus reus, while connected events are considered circumstantial.
In law, the standard of review is the amount of deference given by one court in reviewing a decision of a lower court or tribunal. A low standard of review means that the decision under review will be varied or overturned if the reviewing court considers there is any error at all in the lower court's decision. A high standard of review means that deference is accorded to the decision under review, so that it will not be disturbed just because the reviewing court might have decided the matter differently; it will be varied only if the higher court considers the decision to have obvious error. The standard of review may be set by statute or precedent. In the United States, "standard of review" also has a separate meaning concerning the level of deference the judiciary gives to Congress when ruling on the constitutionality of legislation.
The Testimony of the Evangelists, Examined by the Rules of Evidence Administered in Courts of Justice is an 1846 Christian apologetic work by Simon Greenleaf (1783-1853), an early professor (1833-1848) of the Harvard Law School.
Hearsay, in a legal forum, is an out-of-court statement which is being offered in court for the truth of what was asserted. In most courts, hearsay evidence is inadmissible unless an exception to the hearsay rule applies.
The hearsay provisions of the Criminal Justice Act 2003 reformed the common law relating to the admissibility of hearsay evidence in criminal proceedings begun on or after 4 April 2005.
In eyewitness identification, in criminal law, evidence is received from a witness "who has actually seen an event and can so testify in court".
Eyewitness testimony is the account a bystander or victim gives in the courtroom, describing what that person observed that occurred during the specific incident under investigation. Ideally this recollection of events is detailed; however, this is not always the case. This recollection is used as evidence to show what happened from a witness' point of view. Memory recall has been considered a credible source in the past, but has recently come under attack as forensics can now support psychologists in their claim that memories and individual perceptions can be unreliable, manipulated, and biased. As a result of this, many countries, and states within the United States, are now attempting to make changes in how eyewitness testimony is presented in court. Eyewitness testimony is a specialized focus within cognitive psychology.
The importance of corroboration is unique to Scots criminal law. A long-standing feature of Scots law, the requirement for corroborating evidence means at least two independent sources of evidence are required in support of each crucial fact before an accused can be convicted of a crime. This means, for example, that an admission of guilt by the accused is insufficient evidence to convict in Scotland, because that evidence needs to be corroborated by another source.
