Violation is a legal and form of civil fault in which a binding agreement or negotiated exchange between one or more contracting parties is not rewarded by non-compliance or interference with the performance of the other party. A violation occurs when a party does not fulfill all or part of its contractual obligation, or expresses its intention to fail the undertaking or does not appear to be able, by other means, to fulfil its contractual obligation. In the event of a breach of contract, the damage suffered must be paid by the offence to the victim. The intention to execute a contract in a manner inconsistent with the terms of the contract also shows the intention not to execute the contract. [11] Whether such conduct is so serious that it is a means of renunciation depends on the opposition of the difference in performance that threatens. The intention to achieve results is effective, but willingness in this context does not mean the desire to act despite the inability to do so. Say, „I`d like, but I can`t“ negative intent as much as „I`m not going.“ [12] Contracting parties must strictly execute contracts on their terms: this is what was agreed in the first place when the contract was concluded. There is therefore a need for further offences. The general rule is that contract deadlines are not contractual terms (there are exceptions, for example. B in delivery contracts; they depend in part on the commercial importance of timely delivery in all the circumstances of the case). Therefore, the absence of a service date set in a contract is generally a breach of the guarantee. However, if a contract stipulates that time is essential or otherwise contains an express or implied clause that time is determining delivery, the time conditions will be terms of the contract. If a party does not meet the deadlines, it is a breach of a contractual condition that authorizes the innocent to terminate the contract.
