Legal Instrument

Legal instrument is a legal term of art that is used for any formally executed written document that can be formally attributed to its author, records and formally expresses a legally enforceable act, process, or contractual duty, obligation, or right, and therefore evidences that act, process, or agreement. Examples include a certificate, deed, bond, contract, will, legislative act, notarial act, court writ or process, or any law passed by a competent legislative body in municipal (domestic) or international law. Many legal instruments were written under seal by affixing a wax or paper seal to the document in evidence of its legal execution and authenticity (which often removes the need for consideration in contract law); however, today many jurisdictions have done away with the requirement of documents being under seal in order to give them legal effect. Others, such as Australia, have re-interpreted sealing as a formally attested signature.
