● A contract of surety is an accessory promise by which a person binds himself for another already bound, and agrees with the creditor to satisfy the obligation if the debtor does not. A contract of guaranty, on the other hand, is a collateral undertaking to pay the debt of another in case the latter does not pay the debt.
Strictly speaking, guaranty and surety are nearly related, and many of the principles are common to both. However, under our civil law, they may be distinguished thus: A surety is usually bound with his principal by the same instrument, executed at the same time, and on the same consideration. He is an original promissor and debtor from the beginning, and is held, ordinarily, to know every default of his principal. Usually, he will not be discharged, either by the mere indulgence of the creditor to the principal, or by want of notice of the default of the principal, no matter how much he may be injured thereby. On the other hand, the contract of guaranty is the guarantor's own separate undertaking, in which the principal does not join. It is usually entered into before or after that of the principal, and is often supported on a separate consideration from that supporting the contract of the principal. The original contract of his principal is not his contract, and he is not bound to take notice of its non-performance. He is often discharged by the mere indulgence of the creditor to the principal, and is usually not liable unless notified of the default of the principal.
Simply put, a surety is distinguished from a guaranty in that a guarantor is the insurer of the solvency of the debtor and thus binds himself to pay if the principal is unable to pay while a surety is the insurer of the debt, and he obligates himself to pay if the principal does not pay.

● There is a sea of difference in the rights and liabilities of a guarantor and a surety. A guarantor insures the solvency of the debtor while a surety is an insurer of the debt itself. A contract of guaranty gives rise to a subsidiary obligation on the part of the guarantor. It is only after the creditor has proceeded against the properties of the principal debtor and the debt remains unsatisfied that a guarantor can be held liable to answer for any unpaid amount. This is the principle of excussion. In a suretyship contract, however, the benefit of excussion is not available to the surety as he is principally liable for the payment of the debt. As the surety insures the debt itself, he obligates himself to pay the debt if the principal debtor will not pay, regardless of whether or not the latter is financially capable to fulfill his obligation. Thus, a creditor can go directly against the surety although the principal debtor is solvent and is able to pay or no prior demand is made on the principal debtor. A surety is directly, equally and absolutely bound with the principal debtor for the payment of the debt and is deemed as an original promissor and debtor from the beginning. [Ong vs PCIB, G.R.
