Mahlon Pitney, Wilkinson v. McKimmie — Opinion of the Court
“ For a court of equity looks to substance rather than to form.It is hardly necessary to say that the question whether the contract of the principal has been altered so as to discharge the surety is to be decided according to the essentials, in whatever jurisdiction it may be raised. And so we think the court correctly held that the arrangement that was made between the McKimmies and Horton, of reserving the two lots from the conveyance in order to save the expense of a reconveyance, was not a material change in the contract; that it did not alter the position of either Horton or his sureties ”
