Liability to pay compensation for breach of contract is a type of civil responsibility. The author compares laws and court practices to explain this liability. To be liable for breach of contract, there must be an action that breaks the contract, resulting in harm, and a clear link between the two. Unlike other types of liability, this one doesn't require a mistake to be made. The responsible party must fully compensate for both direct and indirect losses, but there are limits on what can be claimed. The amount of compensation is based on the damage caused, and fines in the contract can be changed to cover losses if approved by a court or arbitration organization.
