Which One Of The Following Agreements Is Lawful

An illegal contract, which is similar to the null contract in that it also has no legal effect between the direct parties, has the added effect that transactions that have a guarantee have also been subject to illegality and we are therefore unenforceable in certain circumstances. Where an agreement is only a guarantee for another agreement or constitutes aid that facilitates the execution of the subject matter of the other agreement, which, although not comprehensible by law, is not prohibited by law, it may be executed as an ancillary agreement. If, on the other hand, it is a mechanism intended to enforce the law actually prohibited, it cannot assert a claim of the agreement, because it is fraught with the illegality of the objective to be achieved, which is made by law. .
