Signature
Encyclopedia
A signature is a handwritten (and sometimes stylized) depiction of someone's name, nickname, or even a simple "X" that a person writes on documents as a proof of identity and intent. The writer of a signature is a signatory. Similar to a handwritten signature, a signature work describes the work as readily identifying its creator. A signature may be confused with an autograph
Autograph
An autograph is a document transcribed entirely in the handwriting of its author, as opposed to a typeset document or one written by an amanuensis or a copyist; the meaning overlaps with that of the word holograph.Autograph also refers to a person's artistic signature...

Function and types of signatures

The traditional function of a signature is evidential: it is to give evidence of:
  1. The provenance of the document (identity)
  2. The intention (will) of an individual with regard to that document

For example, the role of a signature in many consumer contracts is not solely to provide evidence of the identity of the contracting party, but also to provide evidence of deliberation and informed consent.

In many countries, signatures may be witnessed and recorded in the presence of a Notary Public

 to carry additional legal force. On legal documents, an illiterate signatory can make a "mark" (often an "X" but occasionally a personalized symbol), so long as the document is countersigned by a literate witness. In some countries, illiterate people place a thumbprint on legal documents in lieu of a written signature.
There are many other terms which are synonymous with 'signature'. In the United States, one is John Hancock

In the United States, signatures encompass marks and actions of all sorts that are indicative of identity and intent. The legal rule is that unless a statute specifically prescribes a particular method of making a signature it may be made in any number of ways. These include by a mechanical or rubber stamp facsimile. A signature may be made by the purported signer. Alternatively someone else duly authorized by the signer acting in the signer's presence and at the signer's direction may make the signature.

Several cultures whose languages use writing systems other than alphabets do not share the Western notion of signatures per se: the "signing" of one's name results in a written product no different from the result of "writing" one's name in the standard way. For these languages, to write or to sign involves the same written characters. Also see Calligraphy
