Theories of the Common Law of Contracts

Contract is a branch of private law. It thus concerns private obligations that arise in respect of symmetrical relations among natural and artificial persons rather than public obligations that arise in respect of hierarchical relations between persons and the state. Contract, at least in its orthodox expression, is distinctive for concerning chosen, or voluntary, obligations—that is, obligations constituted by the intentions of the contracting parties. This entry describes doctrinal and theoretical accounts of contract law with a special emphasis on the relationship between contract law and two near-neighbors—tort law and fiduciary law.

Section 1 briefly outlines the doctrinal structure of orthodox contract law, with an emphasis on contract’s character as chosen obligation. At the same time, contract law concerns obligations that might also be associated with adjacent bodies of doctrine that elaborate un-chosen obligations—in particular tort law and fiduciary law—and the norms—concerning due care and loyalty—that underlie these involuntary obligations. Section 2 describes encroachments by these bodies of law into contract and the doctrinal, economic, and moral ideas that each employs. Section 3 asks whether contract might remain doctrinally and theoretically separate from tort and fiduciary law and retain its distinctive character as chosen, private obligation.
