All sorts of legal instruments may be reformed by equity, when the errors, which have been committed in the execution of them, are mutual mistakes or a mistake of one party combined with the fraud of the other. Thus, reformation has been decreed of all kinds of deeds of conveyance, including leases, mortgages, deeds of trust, marriage and family settlements. Likewise, bonds of all kinds, policies of insurance, assignments or release of mortgages, executory contracts for the sale of lands, the indorsement of a note, agreements for the establishment of a highway, military orders. So may, also, judgments and other records be corrected or be reformed.
