Based on research, the Commerce Act deems guarantee contract as principal and suretyship as exception. With this, although every suretyship is a responsibility but every responsibility is not a suretyship. Suretyship divides into definite and proportional and principally between debtor and sureties also among sureties suretyship is horizontal. Whether suretyship is vertical or horizontal, surety’s debt would not due with principle debt becoming due with debtor's death or bankruptcy, but, he gains right to compel creditor to take his debt or withdraw from it. The Commerce Act in a courageous endeavor has set before the pledge suretyship and has put that’s regulations as same as the debt suretyship's regulations. The arrangement contract in Commerce Act and the undertaking's guarantee in Civil Act seem as pledge suretyship's clear statutory samples. Despite in normal guarantee, in suretyship debt's or pledge's mortgages would not return with debt’s payment or pledge’s accomplishment. It remains with surety to relying on receive his paid amount or accomplished pledge's equivalent. This is not mortgage's mortgage but mortgage's transfer and in which transfer takes place automatically. So, debtor is required to cooperate for the purpose. In fact, at regulating suretyship, Commerce Act has inserted the pledger’s plurality rules.
