Unconditional Guarantee

An Unconditional Guarantee is an irrevocable, unconditional written payment undertaking issued by a guarantor (usually a bank) at the request of an applicant to a beneficiary. As long as the beneficiary submits claim documents that comply with the guarantee requirements (such as a written demand for payment), the guarantor must pay immediately and may not refuse payment on grounds such as disputes under the underlying contract or defenses raised by the applicant. Use cases include: advance payments for bulk commodity imports, performance of international engineering projects, bid bonds, etc., where the beneficiary seeks strong security independent of the underlying contract. Precautions: the risk to the applicant is extremely high, because after payment the guarantor may seek reimbursement directly from the applicant; the beneficiary must ensure that the claim documents strictly comply with the guarantee terms, otherwise payment may be refused. Difference from a conditional guarantee: a conditional guarantee requires the beneficiary to provide proof of breach or a third-party determination, while an unconditional guarantee pays upon a claim statement alone. Difference from a standby letter of credit: a standby letter of credit is governed by rules such as UCP600, while guarantees are mostly governed by URDG758 or local law.
