Contracts are essential for every business transaction. Whether you are a small business owner, freelancer, or entrepreneur, knowing the critical elements of a legally binding contract is crucial for protecting your interests. So, what 3 things must a contract have? In this guide, I will detail three key elements every contract must include to ensure its validity: mutual assent, consideration, and legal purpose. By the end of this post, you will have the knowledge to draft contracts that withstand legal scrutiny and safeguard your business.

What 3 things must a contract have? - Clarifying Contracts
Before we look at the essential elements, let’s clarify what a contract is. A contract is a legally enforceable agreement between two or more parties that outlines their rights and obligations. Understanding contract law is important, as it varies across jurisdictions and is influenced by local and federal regulations.
Contracts can be verbal or written. However, written contracts are strongly recommended because they provide a clear record of the terms. For a contract to be legally binding, it must include specific required elements, which we will examine in detail.
Mutual Assent
The first key element of a contract is mutual assent, often called the meeting of the minds. This means that all parties involved agree to the terms and clearly understand their rights and obligations. For mutual assent to exist, two fundamental components must be present: an offer and acceptance.
An initial offer is made by one party, specifying the obligations and responsibilities of each side. These details may include:
Price
Scope of work
Deadlines
Any other relevant information
Once the offer is made, the other party can accept, reject, or propose modifications to the offer — known as conditional acceptance. If the terms are modified, it becomes a counteroffer, which the original party must agree to.
For example, consider a freelance web designer proposing a project for a set price of $2,000. The proposal includes the project timeline of four weeks and a detailed list of deliverables. If the client agrees to these terms, mutual assent is achieved.

The consequences of a breach of contract due to a lack of mutual assent can be severe. For instance, if one party claims they didn’t fully understand the terms, it might lead to disputes that could escalate to legal action. Therefore, clarity in the offer and acceptance process is essential for a legally enforceable agreement.
Understanding Legal Consideration
Now that we've established mutual assent, let’s explore the second key element: consideration. This is the exchange of value between the parties involved in the contract. For a contract to be legally binding, there must be consideration; otherwise, it might be deemed void.
Consideration can take many forms, such as:
Money
Services
Promises to perform an action
The value exchanged does not have to be equal. As long as something of value is exchanged, this element is satisfied.
For example, if a photographer agrees to capture images for a fee of $500, both parties are providing consideration — the photographer offers service, and the client offers payment. This principle also applies to service contracts, employment agreements, and real estate transactions.

Moreover, the consideration must exist at the time the contract is formed. For example, if someone promises to pay you for work already completed last month, that would not qualify as valid consideration. Having clear consideration in your contracts can significantly reduce disputes.
Ensuring Legal Purpose
The third key element is that the contract must have a legal purpose. This means the agreement cannot involve illegal activities or violate public policy. If a contract is formed for illegal purposes — such as drug trafficking or fraud — it will be considered void and unenforceable.
For instance, a contract to sell stolen goods would not hold up in court. Additionally, even if the contract’s main purpose is legal, some clauses may still render it illegal. For example, a non-compete clause that severely restricts an individual’s ability to find work could be overturned by a court.
Ensuring that your contracts have a legal purpose helps all parties operate within the law. It is always wise to consult legal experts to ensure that your contracts comply with applicable laws and regulations in your area.
Final Thoughts
Contracts are the backbone of business transactions, and understanding their foundational elements is crucial for every small business owner, freelancer, and entrepreneur. By making sure your contracts include mutual assent, valid consideration, and a legal purpose, you create a solid framework that protects your interests and minimizes the risk of disputes.
While drafting contracts independently is possible, consulting a legal expert familiar with contract law can provide you with valuable insights and guidance.
