A-Z Challenge: I is for Indenture

Indentures usually seem to appear when connected with apprenticeships.  The concept of an indenture was very visual; apart from being a piece of parchment with an agreement written on it, there was also an open secret to an indenture.

The agreement was written and duplicated on the same piece of parchment (with the duplicate known as a chirograph).  A wavy line was drawn - also known as 'indented' - and then the document was cut along the wavy line.  This meant that the different parts could be identified as belonging to each other as long as they fit together correctly.
