Key Takeaways
- Enforceability refers to the legal power of a contract or clause to be upheld by a court or legal authority.
- A contract must include offer, acceptance, consideration, and lawful purpose to be enforceable.
- Courts consider factors like mutual intent, capacity, legality, and clarity of terms when deciding enforceability.
- Unenforceable contracts may arise from illegality, coercion, mistake, vagueness, or failure to meet statutory requirements.
- Distinguishing between a gift and an enforceable agreement depends on the presence of consideration and intent.
- Certain contracts remain valid even if some clauses are unenforceable, thanks to severability provisions.
- Businesses should consider jurisdiction, governing law, and dispute resolution clauses to enhance enforceability.
Enforceability of a contract is when someone can be compelled to observe or forced to obey. It also means something has the capacity to be enforced. Rights and obligations are examples of enforceable things when one party who is obligated to do something is compelled or ordered to go along with the lawful action.
The Potential for Compulsory Action
To rephrase, an enforceable action is one that can be made through compulsion. An example of an enforceable contract is when two or more people make an agreement or contractual obligation that allows one of the parties to lawfully force the other to do something. To be enforceable, a contract needs to have both an offer from one party and an acceptance from another party.
The Rules Under Contract Law
When the parties both agree to and sign a contract, they are then obligated to follow the rules as established under contract law. They are also obligated to do what they've agreed to do. Whether the agreement will be ruled legally enforceable is one of the most important things to consider when negotiating a business contract.
Legal Foundations of Enforceability
Enforceability is rooted in the idea that agreements should have a legal mechanism for enforcement when obligations are not met. Courts examine whether a contract satisfies statutory requirements and adheres to public policy. Beyond the basic elements of offer, acceptance, and consideration, several other factors influence enforceability:
- Capacity: All parties must have the legal ability to contract (e.g., age of majority, mental competence).
- Mutual Intent: There must be a genuine “meeting of the minds,” indicating both parties intended to create a binding agreement.
- Legality of Purpose: Agreements involving illegal activities or against public policy are unenforceable.
- Clarity of Terms: Vague, indefinite, or incomplete terms can make a contract void for uncertainty.
- Compliance with Formalities: Certain contracts (e.g., real estate sales, surety agreements) require written form under the Statute of Frauds to be enforceable.
What Makes a Contract Enforceable?
There are four main factors involved in forming a legally binding, enforceable contract:
- The presentation of an offer
- An acceptance of the offer
- Consideration, or the thing of value offered by each party
- Enforceability
Enforceability Clauses and Their Role
Many contracts include an enforceability clause — a section affirming that the agreement or its specific provisions are legally binding and outlining how disputes will be resolved. Such clauses often specify:
- Governing Law and Jurisdiction: Identifying which state or country’s laws apply reduces ambiguity in enforcement.
- Severability: Allows the remainder of the contract to remain valid even if one clause is found unenforceable.
- Remedies: Stating available remedies (like damages, injunctions, or specific performance) provides clarity and strengthens enforceability.
- Force Majeure: Defining uncontrollable events that excuse performance ensures the contract’s enforceability under unforeseen circumstances.
The Duties of the Parties Agreeing to a Contract
Contracts are built to be legally binding. Once mutually agreed upon, contracts become enforceable agreements between the parties involved. These legally binding agreements can be presented in a court of law whether in written or oral form. The parties who agree to the contract are obligated to execute the deal as arranged in a legally enforceable contract.
What Is an Unenforceable Contract?
The terms of a contract can't be broken without causing the contract to be void. This occurs when one or both of the involved parties violates the agreement by failing to do what they've promised to do. There has to be a valid reason to void the contract for the party victimized by the breach to be able to cancel the agreement.
Common Reasons for Unenforceability
Contracts may fail to meet enforceability standards for several reasons. Common examples include:
- Illegality: Contracts involving unlawful acts or against public policy.
- Lack of Capacity: Agreements signed by minors, incapacitated individuals, or unauthorized representatives.
- Duress or Undue Influence: If consent was obtained through threats, coercion, or manipulation, the contract may be void.
- Misrepresentation or Fraud: False statements that induce a party to agree can render a contract unenforceable.
- Mistake: A fundamental mistake by both parties about a key fact may void the contract.
- Vagueness: If terms are too ambiguous, courts may not enforce them.
Does a Contract Exist?
Sometimes, the court decides the terms applied during the bargaining process were unjust, or a problem may exist within the terms of the contract. If the contract is found to be void in this manner, it becomes as if there never was a contract. To determine if there is a contract and if it has been breached, a court must examine the matter via contract litigation.
Gift or Enforceable Contract?
For a contract to be enforceable, legal analysis needs to uncover three elements, an offer, acceptance of the offer, and the exchange of consideration for the offer. US Federal contract law requires evidence of all elements for an arrangement to be considered a valid contract. Courts must consider:
- The original offer was for something that has value.
- There must be an agreed-upon meeting of the minds.
- Both parties must have the legal capacity to form a contract.
- Contract terms must be stated and definite.
- The offeree has to have the chance to review all terms, or initial intent, of the offer.
- The offeree has to have the chance to accept or reject the offer.
- The second party accepted the offer, making it binding.
- Both parties must clearly indicate approval of contract terms for it to be treated as binding and enforceable.
- Something of value was received in exchange for the offered item or service.
- Consideration was received as agreed.
- Consideration may be monetary in nature or a commitment to perform a service.
Without these things taking place to form an enforceable contract, the exchange is then treated as a gift from the offering party. Also, a legally binding contract cannot be formed regarding illegal activity or immoral behavior as defined by the court.
Partial Enforceability and Severability in Practice
Even if one part of a contract is unenforceable, the entire agreement is not automatically void. Courts often apply the principle of severability, where unenforceable terms are removed while the remaining provisions stay valid and enforceable. This principle is especially common in:
- Non-compete clauses deemed overly broad — courts may strike or narrow them while enforcing the rest of the contract.
- Arbitration clauses — if found invalid, the core agreement may still stand.
- Consumer contracts — courts may remove unfair terms under consumer protection laws while enforcing fair obligations.
The Difference Between Valid and Invalid Contracts
The details of the agreement determine the validity of a contract. If any of the details are missing, a contract is then considered invalid or non-existent. The terms and conditions used in creating the original agreement are more important legally than the monetary value of items or services exchanged.
