The petitioner asserts that since the guarantee it issued was absolute, unconditional, and irrevocable the nature and extent of its liability are analogous to those of suretyship. Its liability accrued upon the failure of the respondents to finish the construction of the Institute of Physical Therapy Buildings in Baghdad. By guaranty a person, called the guarantor, binds himself to the creditor to fulfill the obligation of the principal debtor in case the latter should fail to do so. If a person binds himself solidarily with the principal debtor, the contract is called suretyship. [37] Strictly speaking, guaranty and surety are nearly related, and many of the principles are common to both. In both contracts, there is a promise to answer for the debt or default of another. However, in this jurisdiction, they may be distinguished thus: 1. A surety is usually bound with his principal by the same instrument executed at the same time and on the same consideration. On the other hand, the contract of guaranty is the guarantor's own separate undertaking often supported by a consideration separate from that supporting the contract of the principal; the original contract of his principal is not his contract. 2. A surety assumes liability as a regular party to the undertaking; while the liability of a guarantor is conditional depending on the failure of the primary debtor to pay the obligation. 3. The obligation of a surety is primary, while that of a guarantor is secondary. 4. A surety is an original promissor and debtor from the beginning, while a guarantor is charged on his own undertaking. 5. A surety is, ordinarily, held to know every default of his principal; whereas a guarantor is not bound to take notice of the nonperformance of his principal. 6. Usually, a surety 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. A guarantor 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.
