Defence measures based on the bank`s post-guarantee behaviour. In England, it has never been decided whether this rule applies in cases where the principal debtor is a minor and therefore not liable for the creditor.  If the directors guarantee that their company will execute a contract that is not within their jurisdiction and is therefore not binding on the company, the directors` liability is personally applicable to them.  With respect to the nature of the reference or notification of the guarantee that meets the law of fraud, “a person, after the enactment of this Act, must not give a special commitment to answer for the fault, default or miscarriage of another person written and signed by the party to be taken , or another person legally in his or her care. , is deemed invalid to support a legal action, action or other procedure to incriminate the person who would have been the subject of such a commitment only because the consideration of that undertaking does not appear in writing or by the necessary conclusion of a written document.”  Any writing that embodied the terms of the agreement between the parties and which will be signed by the party to be raised is compliant; and the idea of the agreement should not be in the mind of the person who signed it.  However, it is necessary that the names of the contracting parties appear in writing somewhere; That the mandated party or its agent should sign the agreement or any other document relating to it; and that there is a full agreement on the transcript or memorandum. The memorandum must not be at the same time as the agreement itself.  In addition to the types of conditions found in almost all contracts, there are provisions that are unique for loan guarantee contracts, such as.B.: A guarantee is allowed to benefit from a co-guarantee guarantee with respect to its common liability. This particular right is not the result of a contract, but is based on the equality of the burdens and benefits of participation and insists that the security is in solidarity or solidarity and linked by the same instruments or by other instruments.
