Contract
A legally enforceable agreement between two or more parties.
A contract is an agreement that specifies certain legally enforceable rights and obligations pertaining to two or more parties. It typically involves consent to transfer of goods, services, money, or a promise to transfer any of those at a future date. Contract law, the field of the law of obligations concerned with contracts, is based on the principle that agreements must be honoured. Contracts have existed since antiquity, forming the basis of trade since the dawn of commerce and sedentism during the Neolithic Revolution.

Lore & Background
Contracts have existed since antiquity, forming the basis of trade since the dawn of commerce and sedentism during the Neolithic Revolution. A notable early modern development in contract law was the emergence of the hawala system in the Indian subcontinent and the Arab world, under which a series of contractual relationships formed the basis of an informal value transfer system spanning the Silk Road. In the Indian subcontinent, the hawala system gave rise to the hundi, a transferrable contract entitling its holder in due course to obtain money from its issuer or an agent thereof, giving rise to the principle underlying contemporary negotiable instruments. The hawala system also influenced the development of agency in common law and in civil laws. In Roman law, agents could not act on behalf of other individuals in the formation of binding contracts. On the other hand, Islamic law accepted agency as permissible in not only contract law but in the law of obligations generally, an approach that has since become mainstream in common law, mixed law, and most civil law jurisdictions. Analogously, the transfer of debt, which was not accepted under Roman law, became widely practiced in medieval European commerce, owing largely to trade with the Muslim world during the Middle Ages.
Reader's Guide
Contract law is a foundational element of private law, enabling the creation and enforcement of duties and obligations through prior agreement. It varies between jurisdictions, with common law systems typically requiring consideration for validity, while civil and mixed-law systems require only a meeting of the minds. Contract law is contrasted with tort law, though the emergence of quasi-contracts and quasi-delicts blurs the boundary. Private international law recognizes that each jurisdiction has its own distinct contract law, leading to the common use of choice of law and forum selection clauses. Contract theory addresses why contracts are enforced, with prominent answers focusing on economic benefits or the enforcement of promises, as argued by Charles Fried in Contract as Promise. Relational contract theory and law-and-economics approaches further explore the nature and purpose of contracting.

Frequently Asked Questions
What is a Contract in legal terms?
A contract is a legally enforceable agreement between two or more parties that creates specific rights and obligations. It typically involves a mutual consent to exchange goods, services, money, or a promise to do so at a later date.
What are Contract's key requirements for enforceability?
For a contract to be binding, the parties must genuinely agree to its terms, and the agreement must create obligations that a court can compel. The specific requirements vary by jurisdiction, but the core principle is that once formed, the agreement must be honoured.
How does Contract differ between common law and civil law systems?
In common law jurisdictions, the doctrine of consideration—something of value exchanged by each side—is central to making a contract valid. Civil law traditions, particularly the German one, rely more on abstraction and the concept of a true meeting of the minds between parties.
What are Contract's notable doctrines?
Three stand out across traditions: consideration in common law systems, the principle of abstraction in the German civil-law tradition, and the meeting-of-the-minds requirement in broader civil law frameworks. Each doctrine addresses a different way of confirming that a genuine, enforceable agreement exists.
How old is the concept of Contract?
Contracts date back to antiquity and form the backbone of trade ever since humans became sedentary during the Neolithic Revolution. They have been the foundational mechanism for commerce and obligation for thousands of years.
