obligation

A legal duty, or obligation, arises from either a contract or the law itself. In essence, it's a requirement to act or refrain from acting in a certain way, enforceable by legal means. Contract law, which has roots in Roman law and developed alongside market economies, focuses on agreements between parties. These agreements are generally expected to be freely negotiated between parties of equal bargaining power, though the law includes provisions to protect against unfairness, duress, or unconscionable bargains.123

Legal liability occurs when an individual's actions or omissions cause harm or infringe upon another's rights, potentially requiring compensation. This can stem from intentional acts or negligence, which is the failure to act with reasonable care, even if unintentional. Roman law categorized obligations into those arising from delict (wrongdoing) and contract, with later additions of quasi-delict and quasi-contract. Modern contract law aims to give legal expression to the diverse intentions and purposes individuals pursue through legally binding obligations.452
