“Moreover, it has become not infrequent for creditors to exclude a surety’s “equitable rights” against the creditor, such as his right to be discharged if the creditor agrees to discharge the principal debtor or if the creditor varies the terms of the contract with the principal debtor to his prejudice. At common law, it is clear that these rights in the surety can be excluded by the contract of suretyship.”
“Cases have been cited and authorities have been referred to in Story’s Equity Jurisprudence, which abundantly establish that which is a common and well-known proposition, that where a debt is secured by a surety, it is the business of the creditor, where he has security available for the payment and satisfaction of the debt, to do whatever is necessary to make that security properly available. He is bound, if the surety voluntarily proposes to pay the debt, to make over to the surety what securities he holds in respect of that debt, so that, being satisfied himself, he shall enable the surety to realise the securities and recoup himself the amount of the debt which he has had to pay. That is now a well-known proposition. Here, by registering the bill of sale, and by afterwards availing themselves of the power which they possessed to take possession, the plaintiffs might have secured the payment of the debt to themselves, or by protecting the securities and holding them in their hands they could have made them over to the surety when the surety was willing, or was called on, to pay; but by omitting to do what was necessary in order to place themselves in that position, and by allowing bankruptcy to supervene so as to enable the trustee under the bankruptcy to take possession of these goods adversely, it is clear that they have placed the surety in a position very detrimental and prejudicial to the surety; and for that the surety ought to have, according to the general doctrine, a remedy.”
