Indenture

A written agreement (also called a deed of trust) between a bond issuer and a purchaser that includes, for example, a description of the bond, amount of the issue, working capital and redemption rights or privileges. More generally it can refer to a deed or written contract. The term derives from an old practice of indenting the deed by cutting or tearing it in half with a jagged or indented edge so that the two parts could subsequently be matched by the grantor and the grantee.
