Although all contracts are unique, certain conditions are often used in all contracts, especially in commercial contracts. These are generally referred to as contractual terms. These conditions will determine the rights and responsibilities of both parties. This may include general and specific terms and conditions. A general condition is one that is common and is included in most contracts. The specific conditions are the specific conditions of the contract, i.e. payments, price volatility, sanctions, etc. If a party does not consciously or unconsciously meet the agreed contractual terms, this is referred to as a breach of contract. Depending on the terms of the contract, there may be something that is done intentionally, for example. B the refusal of a job or the refusal to pay for completed work.
