Collateral Covenant Law and Legal Definition

Collateral covenant refers to a covenant that is entered in connection with the grant of something. However, it does not relate immediately to the thing granted. Generally, a collateral covenant is a covenant in a deed or other sealed instrument not pertained to the conveyed property. A collateral covenant appears to be foreign from an instrument, not touching the land or its value, or the value of its reservation, or of a term, but it is a distinct matter put in by parties, which does not appear necessarily to influence the demise or grant.
