A contract is a promise or set of promises that are legally enforceable and, if violated, allow the injured party access to legal remedies. Contract law recognises and governs the rights and duties arising from agreements. If you run a business, and have an existing employment agreement with an employee, and need to alter it, you can use an Employee Agreement Amendment. Sometimes changes are necessary if the work responsibilities have shifted, or if you'd like to reward an employee with more vacation days. An Employment Agreement Amendment is useful when you want to change only one or two terms in an existing contract. If the contract is not required by law to be written, an oral contract is valid and therefore legally binding. The United Kingdom has since replaced the original Statute of Frauds, but written contracts are still required for various circumstances such as land (through the Law of Property Act 1925).

Relevant use cases include on-site emergency services, outsourced medical care, and long-term medical services support. Voidness implies that a contract never came into existence. Voidability implies that one or both parties may declare a contract ineffective at their wish.
