INSTRUMENT, contracts. The writing which contains some agreement, and is so called because it has been prepared as a memorial of what has taken place or been agreed upon. The agreement and the instrument in which it is contained are very different things, the latter being only evidence of the existence of the former. The instrument or form of the contract may be valid, but the contract itself may be void on account of fraud. Vide Ayl. Parerg. 305; Dunl. Ad. Pr. 220.
