What are the facts?
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.
What is the legal issue?
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?
What rule applies?
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).
What did the court hold?
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.
What is the reasoning?
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.
Why is this case significant?
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.
Why didn't the father's moral obligation to repay the caregiver count as consideration?
Consideration requires a bargained-for exchange or a prior legal duty. The caregiver rendered services before any promise and without the father's request, so the services were not induced by the promise. The father had no legal duty to support his adult son. Moral sentiment—gratitude or sympathy—is not a legal detriment or benefit and therefore does not supply consideration.
Would the outcome differ if the son were a minor?
Likely yes. Parents generally have a legal duty to support minor children. If a third party provides necessaries to a minor, the law can impose liability on the parent. A subsequent promise to pay could then be enforceable because it recognizes an antecedent legal duty, bringing the case within a traditional exception to the moral obligation rule.
What if the father had requested the services before they were rendered?
A prior request would likely create a bargain: the caregiver's performance in exchange for the father's promise. That mutual assent and exchange would supply consideration, making the promise enforceable. The timing and inducement—promise leading to performance—are key to satisfying the consideration requirement.
Could the caregiver recover under unjust enrichment or restitution?
Not against the father on these facts. Restitution requires a benefit conferred on the defendant that it would be unjust for the defendant to retain without paying. The benefit ran to the adult son, not the father; the father was not enriched. Any restitutionary claim would lie, if at all, against the son or his estate, not against the father.
How does the modern material benefit rule (Restatement (Second) § 86) affect cases like this?
Section 86 can enforce a promise made in recognition of a benefit previously received by the promisor, to the extent necessary to prevent injustice. But the benefit must have been conferred on the promisor, not a third party, and enforcement is limited and discretionary. In Mills, the father personally received no material benefit; thus, even under § 86, enforcement would be doubtful. The case remains a strong example where neither consideration nor § 86 would likely validate the promise.
