The assignment takes place after the conclusion of the contract; They must not precede them. [Citation required] Prior to the use of this document, the original contract is consulted to ensure that an assignment is not prohibited and that all necessary authorizations have been obtained by the other party to the original contract, known as the debtor. Once this is done, the document can be used. The agreement contains important information such as the identity of all parties to the agreement, the expiry date (if any) of the original contract, whether the original contract requires the debtor`s agreement before rights are assigned, and, if so, the form of consent received by the Zdnessteller and when and which state laws govern the interpretation of the agreement. If the assignment is not pre-existing, the zechter thus gives a tacit guarantee that the right of assignment has not been infiltrated.
