§ 205. Duty Of Good Faith And Fair Dealing
Every contract imposes upon each party a duty of good faith and fair dealing in its performance and its enforcement.
a. Meanings of "good faith." Good faith is defined in Uniform Commercial Code § 1-201(19) as "honesty in fact in the conduct or transaction concerned." "In the case of a merchant" Uniform Commercial Code § 2-103(1)(b) provides that good faith means "honesty in fact and the observance of reasonable commercial standards of fair dealing in the trade." The phrase "good faith" is used in a variety of contexts, and its meaning varies somewhat with the context. Good faith performance or enforcement of a contract emphasizes faithfulness to an agreed common purpose and consistency with the justified expectations of the other party; it excludes a variety of types of conduct characterized as involving "bad faith" because they violate community standards of decency, fairness or reasonableness. The appropriate remedy for a breach of the duty of good faith also varies with the circumstances.
b. Good faith purchase. In many situations a good faith purchaser of property for value can acquire better rights in the property than his transferor had. See, e.g., § 342. In this context "good faith" focuses on the honesty of the purchaser, as distinguished from his care or negligence. Particularly in the law of negotiable instruments inquiry may be limited to "good faith" under what has been called "the rule of the pure heart and the empty head." When diligence or inquiry is a condition of the purchaser's right, it is said that good faith is not enough. This focus on honesty is appropriate to cases of good faith purchase; it is less so in cases of good faith performance.
c. Good faith in negotiation. This Section, like Uniform Commercial Code § 1-203, does not deal with good faith in the formation of a contract. Bad faith in negotiation, although not within the scope of this Section, may be subject to sanctions. Particular forms of bad faith in bargaining are the subjects of rules as to capacity to contract, mutual assent and consideration and of rules as to invalidating causes such as fraud and duress. See, for example, §§ 90 and 208. Moreover, remedies for bad faith in the absence of agreement are found in the law of torts or restitution. For examples of a statutory duty to bargain in good faith, see, e.g., National Labor Relations Act § 8(d) and the federal Truth in Lending Act. In cases of negotiation for modification of an existing contractual relationship, the rule stated in this Section may overlap with more specific rules requiring negotiation in good faith. See §§ 73, 89; Uniform Commercial Code § 2-209 and Comment.
d. Good faith performance. Subterfuges and evasions violate the obligation of good faith in performance even though the actor believes his conduct to be justified. But the obligation goes further: bad faith may be overt or may consist of inaction, and fair dealing may require more than honesty. A complete catalogue of types of bad faith is impossible, but the following types are among those which have been recognized in judicial decisions: evasion of the spirit of the bargain, lack of diligence and slacking off, willful rendering of imperfect performance, abuse of a power to specify terms, and interference with or failure to cooperate in the other party's performance.
