Pre-Existing Duty Rule

Definition

The pre-existing duty rule is a legal principle stating that a party cannot create a valid contract by offering to do something that they are already legally obligated to do. This rule highlights the importance of consideration in contract law, as it requires that something new or additional be exchanged to form a binding agreement.

Review Questions

• How does the pre-existing duty rule affect the enforceability of modifications in contracts?
  • The pre-existing duty rule significantly impacts how modifications are viewed in contract law. When one party seeks to modify an existing contract but offers to do something they are already obligated to do, that promise generally lacks enforceability because it does not constitute new consideration. This means that for any modification to be valid, there must be a new or additional exchange of value between the parties involved.
• What are some exceptions to the pre-existing duty rule, and how do they allow for enforceable contracts?
  • Exceptions to the pre-existing duty rule can arise under certain circumstances, such as when unforeseen difficulties make performance significantly harder than originally agreed. In these cases, if one party offers additional compensation or modifies the agreement due to these new challenges, a court may find that there is valid consideration. This flexibility allows parties to adapt their agreements while still ensuring that some form of new value is exchanged.
• Evaluate the implications of the pre-existing duty rule on contractual negotiations and business relationships.
  • The pre-existing duty rule carries important implications for contractual negotiations and business relationships by emphasizing the necessity of mutual consideration in agreements. This requirement encourages parties to carefully consider their obligations before entering into contracts and fosters transparency during negotiations. Additionally, understanding this rule can prevent disputes and misunderstandings regarding what constitutes valid consideration, ultimately leading to stronger and more reliable business dealings.
