Pre-existing duty rule

Definition

The pre-existing duty rule is a legal principle stating that a party cannot create a valid contract by simply promising to do something that they are already legally obligated to do. This rule plays a crucial role in contract law, as it prevents parties from using existing obligations as consideration for a new agreement, ensuring that there is a genuine exchange of value.

1. The pre-existing duty rule ensures that performance of an existing duty cannot be considered valid consideration for a new contract.
2. This rule helps maintain the integrity of contract law by preventing coercive tactics where one party tries to extract additional benefits for something they are already required to do.
3. In most jurisdictions, if a party is already bound by an existing contract, they cannot use their performance under that contract as consideration for another agreement without additional compensation or modification.
4. Certain exceptions may apply, such as unforeseen circumstances or changes that alter the original duties, which may allow new consideration to be established.

Review Questions

• How does the pre-existing duty rule affect the formation of contracts?
  • The pre-existing duty rule impacts the formation of contracts by establishing that if one party is already obligated to perform a duty, they cannot use that duty as consideration for a new agreement. This ensures that both parties are entering into a contract with fresh commitments and mutual exchanges of value. If an obligation already exists, it cannot simply be re-packaged into a new contract without additional considerations being present.
• Discuss the implications of the pre-existing duty rule on contractual negotiations and how it might influence parties' strategies.
  • The pre-existing duty rule influences contractual negotiations by pushing parties to be clear about their obligations and ensuring that any new agreements reflect genuine changes in duties or compensations. Parties may need to present new terms or conditions that provide real benefits rather than trying to leverage existing obligations. This requirement encourages creative solutions and prevents unfair advantages during negotiation processes, promoting fairness in contractual relationships.
• Evaluate how the pre-existing duty rule interacts with the concepts of consideration and mutual assent in creating enforceable contracts.
  • The pre-existing duty rule interacts closely with the concepts of consideration and mutual assent in that it directly challenges the validity of promises made when there is no new consideration involved. For a contract to be enforceable, there must be mutual assent supported by valid consideration. When one party's performance is merely fulfilling an existing obligation, it undermines the essence of mutual assent because it lacks a true exchange of value. Thus, this rule serves as a filter to ensure only contracts founded on genuine agreements and fresh commitments are deemed enforceable.
