Mills cared for and provided necessaries to Levi Wyman, an adult son of the defendant, after Levi fell ill following a sea voyage. The defendant, Seth Wyman, had not requested these services and bore no legal duty to support his adult son, who was living apart from him. After the services were rendered (and after Levi died, according to many accounts), the father wrote a letter to Mills promising to pay for the expenses incurred in caring for Levi. When the father later refused to pay, Mills brought an action in assumpsit to enforce the promise. The case thus presented a promise made after the benefit was conferred, to compensate a third party for care of the promisor's adult child, with no prior request or legal duty on the promisor's part.
Is a promise to pay for services previously rendered to the promisor's adult son, made after the fact and without any prior legal duty or request by the promisor, enforceable when based solely on moral obligation?
A purely moral obligation does not constitute consideration and cannot render a promise enforceable absent a prior legal obligation or a bargained-for exchange. Traditional exceptions recognize enforceability when the moral obligation is tied to an antecedent legal duty that had become unenforceable for technical reasons (e.g., promises to pay debts barred by the statute of limitations, ratifications of debts incurred during infancy upon reaching majority, or debts discharged in bankruptcy).
No. The father's promise, grounded only in moral obligation and made after the services were rendered without his request and absent any preexisting legal duty to support his adult son, is unenforceable for lack of consideration.
The court, per Parker, C.J., emphasized that enforceable contracts rest on consideration—either a bargained-for exchange or a duty recognized by law. Here, the services were rendered before the promise and without any request by the promisor, so there was no exchange or inducement. Because the son was an adult living apart from his father, the father owed no legal duty to support him; thus, there was no antecedent legal obligation to which the promise could attach. The court recognized that while moral impulses commend the father's promise, such sentiments are not a substitute for legal consideration. Elevating purely moral obligations to legal enforceability would blur the line between ethical duties and legal duties, invite indefinite liability for spontaneous expressions of gratitude, and destabilize the consideration requirement. The court acknowledged limited exceptions—such as promises to pay debts barred by a statute of limitations, ratifications after infancy, or debts discharged in bankruptcy—because in those instances a prior legal obligation existed and the promise revives or recognizes that legal duty. None of those exceptions applied: the father never had a legal duty to pay for his adult son's care, and he received no material benefit from the services. Because the promise lacked consideration and did not fall within a recognized exception, it was a "nudum pactum" and unenforceable. Judgment was entered for the defendant.
Mills v. Wyman is a bedrock authority for the proposition that moral obligation alone does not supply consideration. It is central to understanding the past consideration doctrine and the limited circumstances in which promises recognizing a moral duty are enforceable. The case is routinely contrasted with modern doctrines: restitution (which requires a benefit to the defendant), promissory estoppel (which can enforce certain promises based on reliance), and the material benefit rule (Restatement (Second) of Contracts § 86), under which some promises made in recognition of a benefit conferred may be enforceable. Mills helps students identify when those alternative theories might apply and, just as importantly, when they do not.
Mills v. Wyman cements the principle that the law of contracts protects bargains, not bare promises motivated by sympathy or gratitude. Without a prior legal duty or a bargained-for exchange, a purely moral obligation cannot transform a post hoc promise into an enforceable contract.
