The document that outlines all the conditions of a bond is a “Bond indenture”. A bond indenture is a legal contract between bond issuers and bondholders in which all important and relevant details of a bond are included. For example, this contract should include the terms and conditions of a bond, maturity dates, interest payment, time of payment, method of interest.
A bond contract, on the other hand, is a type of performance bond, a guaranty that the terms and conditions of the contract are fulfilled.
