Written by attorneys · grounded in primary & secondary sources — see below
A contractual obligation requiring each party to act honestly and fairly when performing and enforcing the agreement. The duty prevents a party from taking actions that destroy or injure the other party's right to receive the fruits of the contract. It operates as an implied term in every contract and supplies a standard for evaluating discretionary conduct.

Landlord Disrupts Tenant Sales
Indigo Textiles leased retail space from Inertia Dynamics under a percentage-rent lease. Inertia Dynamics repeatedly closed entrances and conducted disruptive renovations that sharply reduced customer access and sales. Indigo Textiles sued for breach after its revenue collapsed. The conduct violated the implied duty because Inertia Dynamics exercised its management rights to frustrate the central benefit Indigo Textiles reasonably expected from the lease.
Partner Alters Good-Faith Standard
Ian Iverson and Ivy Ibarra formed a general partnership to operate a consulting firm. Their agreement attempted to eliminate the obligation of good faith and fair dealing under the statute while substituting a manifestly unreasonable measurement standard. Ivy Ibarra later challenged the clause after Ian Iverson withheld information to gain a personal advantage. The attempted elimination was ineffective because the statute permits only non-manifestly-unreasonable standards to govern the obligation.
Limited Partner Withholds Fees
Integrity Partners, a limited partnership, received licensing revenue from a client introduced through limited partner Ismael Ibrahim. Ibrahim diverted the opportunity to his separate entity and retained the fees. The general partner sued, alleging breach of the good-faith obligation. Ibrahim's conduct violated the duty because limited partners must discharge their duties consistently with good faith and fair dealing under the statute.
Threat to Withhold Performance
Insight Consulting contracted with Isabelle Inman to provide ongoing advisory services. When market conditions changed, Insight Consulting threatened to stop performance unless Inman agreed to a substantial price increase. Inman refused and sued for breach. The threat constituted an improper means because it breached the duty of good faith and fair dealing under the existing contract.
Partner Diverts Partnership Funds
Ibrahim Iqbal and Imani Idowu operated a general partnership selling textiles. Iqbal used partnership funds to pay personal expenses without disclosure or consent. Idowu sued for breach after discovering the diversions. Iqbal's conduct violated the statutory obligation because partners must discharge their duties consistently with good faith and fair dealing.
Limited Partner Conceals Opportunity
Inertia Dynamics, a limited partnership, pursued a client contract that limited partner Ivy Ibarra secretly redirected to her own company. Ibarra retained all resulting profits without disclosure. The general partner demanded an accounting. Ibarra's actions breached the obligation because limited partners must exercise rights consistently with good faith and fair dealing.
Common questions
Frequently Asked
5
Does the duty apply only during contract formation?+
No. The duty applies to performance and enforcement of the contract. Conduct after formation that frustrates the other party's expected benefits can constitute a breach even when no express term is violated.
Supporting sources
Can parties eliminate the duty by agreement in a general partnership?+
No. A partnership agreement may prescribe reasonable standards for measuring the obligation but cannot eliminate it outright. Any attempt to remove the duty entirely is ineffective under the statute.
Does bad-faith rejection of goods after market prices fall breach the duty?+
Yes. When a buyer accepts initial deliveries without objection and then rejects later conforming goods for pretextual reasons after prices drop, the conduct violates the duty of good faith and fair dealing and constitutes a breach of contract.
Supporting sources
Does the duty limit an insurer's claim-handling practices?+
Yes. An insurer that repeatedly demands duplicative documentation, orders unnecessary examinations, and presses for an unfairly low settlement breaches the duty by creating unjustified obstacles to the policyholder's receipt of benefits.
Supporting sources
Does the duty prevent a lender from blocking draws after a minor technical default?+
Yes. A lender that refuses further draws after a minor default while continuing to collect commitment fees and suggesting future funding may resume acts in bad faith by undermining the purpose of the credit facility.
