Introduction

When it comes to contracts, many people assume that they must be in writing to be enforceable. However, this is not always the case. In fact, some contracts can be enforced even if they are not in writing. This article will explore the concept of unwritten contracts, their enforceability, and the circumstances under which they can be enforced.

What are Unwritten Contracts?

Unwritten contracts, also known as oral contracts, are agreements between two or more parties that are not reduced to writing. These contracts can be verbal or implied, and they can be just as binding as written contracts. However, the enforceability of unwritten contracts depends on various factors, which we will discuss later in this article.

The Statute of Frauds

The Statute of Frauds is a law that requires certain types of contracts to be in writing and signed by the parties involved. These contracts include:

Contracts for the sale of real estate
Contracts for the sale of goods worth more than $500
Contracts for the sale of personal property worth more than $5,000
Contracts for the sale of goods that are not to be delivered within a reasonable time
Contracts that are not to be performed within a year from the date of the contract

If a contract falls under one of these categories, it must be in writing and signed by the parties involved to be enforceable. However, if the contract does not fall under one of these categories, it can still be enforced even if it is not in writing.

The Doctrine of Promissory Estoppel

The doctrine of promissory estoppel is a legal principle that allows a court to enforce an unwritten contract if one party has made a promise to another party and the other party has relied on that promise to their detriment. This doctrine is often used in cases where a party has made a verbal promise to another party, but the promise is not in writing.

The Doctrine of Implied-in-Fact Contract

An implied-in-fact contract is a contract that is not explicitly stated, but can be inferred from the circumstances. For example, if a person hires a contractor to build a house, and the contractor begins working on the house without a written contract, an implied-in-fact contract may exist. This type of contract can be enforced if the parties involved have acted in a way that suggests they intended to enter into a contract.

The Doctrine of Quasi-Contract

A quasi-contract is a contract that is not explicitly stated, but is implied by law. This type of contract is often used in cases where one party has made a mistake or has been unjustly enriched. For example, if a person hires a contractor to build a house, but the contractor fails to complete the job, a quasi-contract may exist. This type of contract can be enforced if the parties involved have acted in a way that suggests they intended to enter into a contract.

Circumstances Under Which Unwritten Contracts Can Be Enforced

Unwritten contracts can be enforced in the following circumstances:

Parties have acted in a way that suggests they intended to enter into a contract: If the parties involved have acted in a way that suggests they intended to enter into a contract, an unwritten contract may exist.
One party has made a promise to another party and the other party has relied on that promise to their detriment: If one party has made a promise to another party and the other party has relied on that promise to their detriment, an unwritten contract may exist.
The parties have engaged in a course of conduct that suggests they intended to enter into a contract: If the parties involved have engaged in a course of conduct that suggests they intended to enter into a contract, an unwritten contract may exist.

Conclusion

In conclusion, unwritten contracts can be enforced even if they are not in writing. The enforceability of unwritten contracts depends on various factors, including the Statute of Frauds, the doctrine of promissory estoppel, the doctrine of implied-in-fact contract, and the doctrine of quasi-contract. If you are involved in a contract dispute, it is essential to seek the advice of a qualified attorney who can help you navigate the complexities of contract law.
