Given that many contractual disputes, perhaps the majority, result from a disagreement over the importance of contractual provisions, treaty interpretation is an important area. If time is not essential, a violation of the deadline does not necessarily constitute a violation that allows the creditor to cancel. Once Mora has entered, the creditor may take time to enter by authorizing the right of withdrawal, allowing him to terminate the contract. It is not an interpellatio that determines when Mora, not demolition, will occur. Simply put, a contract is an agreement between two or more parties with the serious intention of creating a legal obligation. Contracts are essential to settle certain relationships because they provide certainty about what the parties expect from each other. Contracts provide a legal framework that governs exchanges between the parties and that recognizes that the law respects and, if necessary, enforces their agreements. It can therefore be said that contracts contribute to order in society. When the parties enter into a contract, obligations are created.
An obligation to do so is a legal relationship that consists of a right of benefit of the other party, with a corresponding obligation to accomplish “your end of good business”. Corrective measures are either for the performance or termination or termination of a contract. Full benefit is the natural cause of termination of a contract. Since a violation interferes with good performance, the main remedy is therefore to be enforcement. Whistleblowing is an exceptional remedy. As a general rule, a breach occurs when a party fails to comply with its contractual obligations without making a legal apology. Innovation is an agreement to terminate one or more commitments and replace them with a new commitment or obligation. According to Hugo Grotius, “an obligation is released on the terms of another obligation at the same time as it takes its place.”  If the initial commitment is cancelled, innovation is also unsealed. In South Africa, there are two forms of innovation: novatio voluntaria and novatio necessaria. The transfer of fiduciary security is an ordinary assignment of a personal right as collateral related to a trust contract that is an ordinary contract. In the event of a security of a personality right, the ownership of the right of the person is retained by the assignor, while only the quasi-ownership is transferred to the creditor of the transfer (pfand).
If no date is set, the benefit must be completed “within a reasonable period of time,” itself determined by the nature of the contract. Concrete Products v Natal Leather Industries is the most important case in determining reasonable time. In this case, the plaintiff agreed to sell to the defendant a large number of steel wedges for suitcases of different sizes. The agreement stipulated that several thousand of all sizes should be delivered weekly and that the order should be considered urgent for small corners. No time has been set for the start of delivery. The applicant did not provide the small corners, although the defendant insisted that the contract be executed. He did, however, send middle corners that were accepted by the defendant in accordance with the contract. Due to the non-delivery of the small corners, the defendant informed the applicant of the termination approximately three weeks after the contract was concluded.
