A more thorough explanation:

An express contract is a type of agreement between two or more parties where the terms of the contract are clearly stated either verbally or in writing. This means that the parties involved have agreed to be bound by the terms of the contract that have been explicitly stated.

For an express contract to be valid, it must include:

• Mutual intent to be bound
• A definite offer
• Unconditional acceptance
• Consideration

An express contract is different from a contract-implied-in-fact. A contract-implied-in-fact is an agreement where the obligations arise from a mutual agreement and intent to promise, but the agreement and promise have not been expressed in words. In other words, the terms of the contract are not explicitly stated.

Both types of contracts require mutual assent and a meeting of the minds. However, an express contract is proved by an actual agreement (either written or oral), while a contract-implied-in-fact is proved by circumstances and the conduct of the parties.

Here are some examples of express contracts:

• A written contract between a landlord and a tenant that clearly states the terms of the lease agreement, such as the rent amount, the length of the lease, and the security deposit.
• An oral agreement between a homeowner and a contractor to remodel a kitchen, where the contractor clearly states the scope of work, the timeline, and the cost of the project.

These examples illustrate the definition of an express contract because in both cases, the terms of the agreement are clearly stated either in writing or verbally. The parties involved have agreed to be bound by the terms of the contract that have been explicitly stated.
