Key Takeaways

  • Nudum pactum means “naked agreement,” a contract without consideration, making it unenforceable in law.
  • While agreements may be verbal or written, they must be “dressed” with consideration to be valid.
  • Exceptions exist: contracts under seal or formal instruments like promissory notes may still be binding.
  • English and U.S. law generally reject enforcement of nudum pactum, especially in government contracts.
  • Modern law emphasizes mutual benefit and consideration as essential to contractual obligations.

Nudum pactum is a Latin term that translates as "naked agreement." In law, it is an agreement in which there is no consideration. This means the agreement is not legally enforceable by law because it is not "dressed" with consideration, as legally required. As a nudum pactum is not legally binding or enforceable, it's best to be avoided.

What Is a Nudum Pactum?

A nudum pactum may be in verbal or written form. These agreements may not result in legal action, since they are naked contracts. This means that the agreements do not fall within the specific categories of agreements that can provoke legal action. However, an agreement may create a modification of or exception to an obligation already in effect.

However, if the contract is under seal, it is considered valid. In addition, some contracts exist, which, as a result of their forms, carry a consideration, including bills of exchange, sealed instruments, and promissory notes. These are considered valid even though no official consideration exists within them.

English law does not enforce any nudum pactum. An exceedingly large amount of agreements (bare agreements, that is) are made daily, and it does not make sense if every one of them were to be established as binding contracts. As an example, Joe and Ann agree that Joe will sell his truck to him in three months. However, during those three months, he decides not to sell his truck after all and withdraws from the promise. Legally, there has been no breach of contract, as no consideration was made.

In particular, government contracts need to be wary of conducting any actions under a bare agreement. To put it simply, a contractor will most likely not be compensated for goods or services. As opposed to valid contracts, there will be no legal recourse available from the Court of Federal Claims or the Boards.

This issue often occurs when the contract includes at least one "availability of funds" clause. If your contract contains one of these clauses, it is considered a bare agreement until the contracting party receives the funds and then supplies the contractor with appropriate notice of the availability of funds. In short, it's best not to supply any goods or deliver services until you'd received written notice of the availability of funds, as you are unlikely to ever receive your payment.

Historical Origins of Nudum Pactum

The concept of nudum pactum traces back to Roman law, where informal promises lacking formalities or consideration were deemed unenforceable. Medieval English courts adopted the doctrine, stressing that a mere promise without something of value in return was insufficient to bind parties legally. Over time, this principle helped shape the common law requirement of consideration, a cornerstone of contract law still relevant today.

Legal Consequences of Nudum Pactum

Because a nudum pactum lacks consideration, courts will not enforce it. This has several consequences:

  • Unenforceability: Parties cannot seek damages or compel performance.
  • Reliance risk: The promisee risks loss if they act based solely on the agreement.
  • Government contracts: Bare agreements are especially problematic when contracts depend on “availability of funds” clauses, leaving contractors unpaid until funds are appropriated.

However, once consideration is supplied—such as payment, exchange of value, or reliance recognized under doctrines like promissory estoppel—the agreement may transition from unenforceable to binding.

Examples of Nudum Pactum

To be effective, a contract must be based upon a consideration. For example, an agreement by a party with no interest in the exchange, to pay a certain fee if an exchange occurs, is legally invalid, unless it is supported by the appropriate consideration. A new contract must be premised on a consideration in the release of an existing debt for commissions as a result of an agreement for the sale of real estate.

  • If Alice were to show a house to a party that is interested in renting from the owner, an agreement made by the owner to pay Alice for her service lacks consideration if made after the fact. If a broker had agreed to conduct an exchange of property and had earned commission through a previously made valid contract, any agreement made afterward (for example, a claim that the broker was not entitled to a commission) is without consideration. However, a broker cannot claim entitlement to commission in the same situation if the broker actually did not perform any services, and cannot prove that he or she was excused from providing such service.
  • As another example, if an agent agrees to reduce commissions through a misstatement, it is considered to be lacking consideration. An agreement made under a mistaken belief to pay a commission also lacks consideration, as no service had been conducted, and thus the broker's recovery is not valid.
  • If a defendant entered an agreement to pay the plaintiff the appropriate amount of their services, and no agreement existed that stated the monetary amount should be determined by the defendant, such an agreement does not contain mutual consent or consideration and is not legally enforceable.
  • If a property owner withdrew a broker's authority to sell the property and informed the broker that they would be compensated as if they had made the exchange, and then the owner sold the property through their own efforts, the agreement made to the broker is without consideration.

Nudum Pactum vs. Enforceable Contracts

The key difference between nudum pactum and enforceable contracts lies in consideration:

  • Nudum Pactum: A bare promise (e.g., “I’ll give you $1,000 tomorrow” without anything in return).
  • Valid Contract: A mutual exchange (e.g., “I’ll pay you $1,000 if you paint my house”).

Legal dictionaries such as Black’s Law Dictionary and Justia define nudum pactum as a commitment or pledge made without mutual exchange of value, rendering it void of legal force.

Courts also distinguish between gratuitous promises (nudum pactum) and contracts formalized by instruments or seals, which may remain enforceable despite lacking explicit consideration.

Modern Perspectives on Nudum Pactum

While the strict doctrine of nudum pactum has faded, its principles continue to influence modern contract law. Courts frequently revisit the idea when determining whether:

  • Gifts constitute enforceable promises.
  • Employment agreements lack sufficient consideration.
  • Oral promises are binding without supporting action.

In today’s legal practice, doctrines like promissory estoppel have softened the rigid requirement for consideration by allowing enforcement when one party reasonably relies on a promise to their detriment. Still, the concept of nudum pactum serves as a cautionary reminder that promises unsupported by value are generally outside the scope of enforceable law.

Frequently Asked Questions

    Generally no, unless formalized under seal, tied to a promissory note, or supported by doctrines like promissory estoppel.
  3. Why is consideration important in avoiding nudum pactum?
    Consideration ensures that both parties give or receive something of value, making the agreement binding in court.
  4. Are nudum pactum agreements common today?
    They are rare in formal contracts but appear in casual promises or in government contracts with conditional funding.
  5. How does nudum pactum relate to gift promises?
