Key Takeaways
- Enforceable law definition means an agreement meets legal requirements and can be upheld by courts.
- Not all agreements are enforceable—valid contracts require offer, acceptance, consideration, capacity, and legality.
- Certain contracts must be in writing under the Statute of Frauds, such as real estate and prenuptial agreements.
- Promises alone are not enforceable without consideration or legal recognition.
- Liens are enforceable claims on property to secure repayment of debts.
- Enforceability depends on intent, legality, and adherence to formalities.
- Void, voidable, and unenforceable contracts differ in whether they lack legality, capacity, or evidentiary support.
Enforceable law definition means that an agreement has been made by two or more parties and includes the components of a valid contract. For a contract to be valid, there must be an offer, a consideration, and the parties involved must be of full mental capacity. If one party is deemed incompetent by a judge, the contract will not be enforceable.
Is an Agreement/Contract Enforceable By The Law?
It should be noted that all contracts are agreements, but not all agreements are contracts. Agreements and contracts that are properly prepared and contain all the required components are enforceable by the law. To be sure all requirements are met, a review by a lawyer is recommended. If something is missed, the agreement/contract may be unenforceable. Regardless of country, if a contract meets the requirements it will be seen as legally binding and will be enforced.
Contracts and agreements that meet all legal requirements but contain actions or products that are illegal will result in the contract being voided. If the contract contains any clauses that are against the law, they will not be enforced.
Contracts that must be in writing to be enforced by the law are listed under the statute of frauds. The contract types may vary by state but common contracts that must be in writing include:
- Marriage contracts.
- Prenuptial agreements.
- Contracts that will take longer than one year to complete.
- Buying and selling of real estate.
- Executory contracts.
- Goods and services above a set amount, usually $500 or more.
- Insurance contracts.
- Taking legal liability for another party.
Common Barriers to Enforceability
Even if a contract appears valid, several issues can render it unenforceable. Examples include:
- Lack of capacity: Contracts signed by minors or individuals deemed mentally incompetent may be void or voidable.
- Duress or undue influence: Agreements signed under coercion or manipulation may not hold up in court.
- Mistake or misrepresentation: If parties enter into a contract based on fraud, misrepresentation, or a fundamental mistake, enforceability is compromised.
- Public policy violations: Contracts that promote illegal activities (such as unlicensed gambling or unsafe employment practices) cannot be enforced.
Courts evaluate these circumstances carefully to ensure fairness and compliance with legal principles.
Legal Purpose and Legal Obligation
A legal purpose in contract law is an essential component of an agreement. The agreement is legally binding as long as it includes legal activities and actions. A legal obligation is taking the action or abstaining from an action based on the legality of the obligation. When writing a contract, the agreement made must have a legal purpose. If it is not legal, there is a legal obligation to not follow through with the contract.
The contract must also meet the legal requirements that define a contract. This includes the following:
- An offer must be made between the parties.
- The offer must be accepted.
- A lawful consideration must be agreed upon by all parties.
- The parties must be of full mental capacity.
- The parties must be over the age of 18. If not, an adult cosigner is required.
- The contract must have a legal purpose.
- The contract must be signed free of duress.
The contract should be signed by all parties, and witnesses should be used to help validate the contract if future legal issues arise.
Void, Voidable, and Unenforceable Contracts
Understanding the distinctions between void, voidable, and unenforceable contracts helps clarify enforceability:
- Void contracts are invalid from the start because they lack a lawful object or purpose (e.g., a contract to commit a crime).
- Voidable contracts are valid until one party chooses to rescind them, often due to lack of capacity, fraud, or undue influence.
- Unenforceable contracts may satisfy the elements of a contract but cannot be upheld in court due to procedural issues, such as failing to meet statutory writing requirements.
These categories emphasize that legality alone is not enough—contracts must also meet formalities and fairness standards.
Are Promises Legally Enforceable
At the core, a contract is a promise or collection of promises agreed upon by two or more parties. The law of contracts is the body of law that was put in place to create the guidelines that enforce contracts. This relates to the formation, interpretation, and performance of the contract. The laws also dictate how to proceed if there is a failure of the parties to perform the promises listed in the contract.
In the court system, the consideration is seen as the most obvious choice for enforcement. The consideration is what the parties of the contract agreed to at the time of signing. This means they agreed to complete a task in exchange for money or another action.
Role of Consideration and Intention
Consideration—the exchange of value—is central to enforceability. A promise becomes legally binding when each party gives or receives something of value, whether money, services, or mutual obligations. Courts also look at intention to create legal relations. Social or domestic agreements (like promising to host a family dinner) typically lack enforceability, while commercial promises are presumed to be legally binding.
What is a Lien
An official claim or charge called a lien is used when payment is owed for services rendered or for payment on a property that is owned. A lien is a formal document that is signed by the person who is owed money or by the debtor who has agreed to pay the outstanding amount due. The lien is then used as a way to show the legal right to sell property to fulfill the outstanding balance.
In real estate, a mortgage or deed of trust is a type of lien. All liens, to be enforced, must be recorded with the county recorder. The lien against the debtor's property is made when an abstract of judgment converts the judgment into a lien.
Examples of liens include:
- A lien placed by a landlord on a tenant's property for unpaid rent.
- A tax lien, which is used by the government to collect unpaid taxes.
- A lien placed by an attorney against a client who has not paid for services rendered.
Enforceability in Different Legal Contexts
Enforceable laws apply not only to contracts but to many legal settings:
- Employment contracts: Courts enforce obligations like wages and workplace safety, provided agreements comply with labor laws.
- Consumer contracts: Laws protect consumers against unfair terms, ensuring enforceability aligns with public interest.
- Family law agreements: Prenuptial and separation agreements must meet statutory requirements and fairness standards to be enforced.
- Business transactions: Commercial contracts, partnership agreements, and service contracts must meet the enforceability test to protect business interests.
This broader view of enforceability highlights its importance across multiple areas of law.
