Contract guarantee (known also as ancillary guarantee)[1]is a common way to secure the implementation of contracts and is a type of guarantee in which guarantor not only gives letter of credit, but also becomes a co-signatory of the contract. That means that he is able to challenge obligee's demand for payment of the guarantee sum.It is also an obligation of the insurance company to pay to the beneficiary a certain amount, that is to say the amount of the guarantee sum if the applicant fails to meet his obligations, which is part of the guarantee. They are a key element for contractors and subcontractors who take active part in tenders and execute contracts and, therefore, are obliged to provide collateral for investors and general contractors. If there are entities that contain many contracts and often take part in tenders, it is necessary to conclude a general agreement that ensures better obtaining of warranty documents.

Contract guarantees are not allowed in certain countries, e.g. in U.S.
