Authentication (law)
Authentication, in the law of evidence, is the process by which documentary evidence and other physical evidence is proven to be genuine, and not a forgery. Generally, authentication can be shown in one of two ways. First, a witness can testify as to the chain of custody through which the evidence passed from the time of the discovery up until the trial. Second, the evidence can be authenticated by the opinion of an expert witness An expert witness, particularly in common law countries such as the United Kingdom, Australia, and the United States, is a person whose opinion by virtue of education, training, certification, skills or experience, is accepted by the judge as ... examining the evidence to determine if it has all of the properties that it would be expected to have if it were authentic. For handwritten documents, any person who has become familiar with the purported author's handwriting prior to the cause of action from which the trial arose can testify that a doc ...

Evidence (law)
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 quantum of evidence is the amount of evidence needed; the quality of proof is how reliable such evidence should be considered. Important rules that govern admissibility concern hearsay, authentication, relevance, privilege, witnesses, opinions, expert testimony, identification and rules of physical evidence. There are various standards of evidence, standards sh ...

Documentary Evidence
Documentary evidence is any evidence that is, or can be, introduced at a trial in the form of documents, as distinguished from oral testimony. Documentary evidence is most widely understood to refer to writings on paper (such as an invoice, a contract or a will), but the term can also apply to any media by which information can be preserved, such as photographs; a medium that needs a mechanical device to be viewed, such as a tape recording or film; and a printed form of digital evidence, such as emails or spreadsheets. Normally, before documentary evidence is admissible as evidence, it must be proved by other evidence from a witness that the document is genuine, called " laying a foundation". Documentary v. physical evidence A piece of evidence is ''not'' documentary evidence if it is presented for some purpose other than the examination of the contents of the document. For example, if a blood-spattered letter is introduced solely to show that the defendant stabbed the author of ...

Physical Evidence
In evidence law, physical evidence (also called real evidence or material evidence) is any material object that plays some role in the matter that gave rise to the litigation, introduced as evidence in a judicial proceeding (such as a trial) to prove a fact in issue based on the object's physical characteristics. In American law Tampering It is an offense at common law "to tamper with, conceal, or destroy evidence knowing that it may be wanted in a judicial proceeding or is being sought by law enforcement officers."67 Corpus Juris Secundum ''Obstructing Justice'' ยง 63 (footnotes omitted). This is also a crime under statutes of many U.S. states. A 2004 review found that 32 states had a statute "that prohibits, in some form, the concealment, destruction, or tampering with evidence."John F. Decker, ''The Varying Parameters of Obstruction of Justice in American Criminal Law'', 65 LA. L. Rev. 40, 83-84 (2004). Evidence tampering "generally refers to physical evidence and is not f ...

Chain Of Custody
Chain of custody (CoC), in legal contexts, is the chronological documentation or paper trail that records the sequence of custody, control, transfer, analysis, and disposition of materials, including physical or electronic evidence. Of particular importance in criminal cases, the concept is also applied in civil litigation and more broadly in drug testing of athletes and in supply chain management, e.g. to improve the traceability of food products, or to provide assurances that wood products originate from sustainably managed forests. It is often a tedious process that has been required for evidence to be shown legally in court. Now, however, with new portable technology that allows accurate laboratory quality results from the scene of the crime, the chain of custody is often much shorter which means evidence can be processed for court much faster. The term is also sometimes used in the fields of history, art history, and archives as a synonym for provenance (meaning the chronolo ...

Expert Witness
An expert witness, particularly in common law countries such as the United Kingdom, Australia, and the United States, is a person whose opinion by virtue of education, training, certification, skills or experience, is accepted by the judge as an expert. The judge may consider the witness's specialized (scientific, technical or other) opinion about evidence or about facts before the court within the expert's area of expertise, to be referred to as an "expert opinion". Expert witnesses may also deliver "expert evidence" within the area of their expertise. Their testimony may be rebutted by testimony from other experts or by other evidence or facts. History The forensic expert practice is an ancient profession. For example, in ancient Babylonia, midwives were used as experts in determining pregnancy, virginity and female fertility. Similarly, the Roman Empire recognized midwives, handwriting experts and land surveyors as legal experts. The codified use of expert witnesses and ...

Handwriting
Handwriting is the writing done with a writing instrument, such as a pen or pencil, in the hand. Handwriting includes both printing and cursive styles and is separate from formal calligraphy or typeface A typeface (or font family) is the design of lettering that can include variations in size, weight (e.g. bold), slope (e.g. italic), width (e.g. condensed), and so on. Each of these variations of the typeface is a font. There are thousands o .... Because each person's handwriting is unique and different, it can be used to verify a document's writer. The deterioration of a person's handwriting is also a symptom or result of several different diseases. The inability to produce clear and coherent handwriting is also known as dysgraphia. Uniqueness Each person has their own unique style of handwriting, whether it is everyday handwriting or their personal signature. Cultural environment and the characteristics of the written form of the first language that one learns to ...

Self-authenticating Documents
A self-authenticating document, under the law of evidence in the United States, is any document that can be admitted into evidence at a trial without proof being submitted to support the claim that the document is what it appears to be. Several categories of documents are deemed to be self-authenticating: #Certified copy of public or business records; #Official publications of government agencies; #Newspaper articles; #Trade inscriptions, such as labels on products; #Acknowledged documents (wherein the signer also gets a paper notarized); and #Commercial paper under the Uniform Commercial Code. Although most U.S. states have evidentiary rules similar to the Federal Rules of Evidence, the California Evidence Code diverges significantly from the FRE in that it does not treat trade inscriptions as self-authenticating.See ''Dicola v. White Brothers Performance Prods.''158 Cal. App. 4th 666(2008) (holding that product label was hearsay). This means that if a defendant does not stipul ...

Ancient Document
{{Evidence law An ancient document, in the law of evidence, refers to both a means of authentication for a piece of documentary evidence, and an exception to the hearsay rule. Authentication With respect to authentication, an "ancient document" is one that may be deemed authentic without a witness to attest to the circumstances of its creation because its age suggests that it is unlikely to have been falsified in anticipation of the litigation in which it is introduced. Under the American Federal Rules of Evidence First adopted in 1975, the Federal Rules of Evidence codify the evidence law that applies in United States federal courts. In addition, many states in the United States have either adopted the Federal Rules of Evidence, with or without local v ... ("FRE"), a document is deemed authentic if it is: #at least twenty years old; #in a condition that makes it free from suspicion concerning its authenticity; and #found in a place where such a writing was likely to be ...
