Contracts are essential tools for establishing legally binding agreements between parties, outlining rights, responsibilities, and terms. Knowing the foundational principles of contract law can help ensure your agreements are clear, enforceable, and legally valid. Here’s a guide to the basic principles of contract law, from offer and acceptance to legality and capacity.
For more guidance on drafting enforceable contracts, check out our Step-by-Step Guide to Drafting a Contract and Common Legal Pitfalls, where we discuss how to avoid mistakes in contract drafting.
1. Offer and Acceptance
Principle: A contract begins with an offer from one party and acceptance by the other, forming a mutual agreement.
- Key Points: The offer must be clearly stated and specific in terms. Acceptance must be unconditional and communicated to the offeror.
- Example: If a contractor offers to build a deck for $5,000 and the homeowner agrees to the price and terms, they’ve reached a mutual agreement.
Internal Link: For tips on structuring clear offers, see our Step-by-Step Guide to Drafting a Contract.
2. Consideration
Principle: Consideration is something of value exchanged between parties, such as money, goods, services, or promises. It’s what each party gives to make the contract binding.
- Key Points: Both parties must offer something of value, which can be monetary or a commitment to perform (or refrain from) a specific action.
- Example: In a freelance contract, the freelancer agrees to provide design services (consideration), while the client agrees to pay $2,000 (consideration).

3. Mutual Consent
Principle: Both parties must willingly and knowingly agree to the contract terms. This is also known as “meeting of the minds.”
- Key Points: Mutual consent means that each party fully understands the terms and agrees without any form of coercion, manipulation, or misunderstanding.
- Example: If one party signs a contract under pressure, the agreement may be deemed unenforceable due to lack of consent.

4. Capacity
Principle: All parties must have the legal capacity to enter into a contract. Minors, people of unsound mind, and individuals under the influence are generally considered unable to contract.
- Key Points: Parties must be of legal age and sound mind. Otherwise, the contract may be voidable.
- Example: A contract signed by a minor may be voided, as they lack legal capacity in most jurisdictions.
5. Legality of Purpose
Principle: The contract’s purpose must be legal and not against public policy. Contracts that involve illegal activities or violate public policy are unenforceable.
- Key Points: Contracts must not involve illegal actions, like agreements for unlicensed gambling or transactions that violate regulatory laws.
- Example: An agreement to sell prohibited substances would be void because it involves an illegal purpose.
6. Certainty and Clarity of Terms
Principle: Contract terms must be clear, specific, and certain. Ambiguities can lead to misunderstandings and make it difficult to enforce the contract.
- Key Points: Clearly define each party’s obligations, responsibilities, and rights to prevent confusion or disputes.
- Example: Instead of saying “prompt delivery,” specify “delivery within 10 business days” to avoid ambiguity.
Internal Link: For tips on avoiding vague language, refer to our Common Legal Pitfalls.
7. Written vs. Oral Contracts
Principle: While oral contracts can be binding, written contracts are generally preferred because they provide a clear record of terms. Some contracts, such as real estate agreements, must be in writing to be enforceable under the Statute of Frauds.
- Key Points: Written contracts are legally required for certain agreements, like property sales or leases longer than one year.
- Example: A real estate agreement must be in writing to be enforceable, but a simple service agreement can be binding even if agreed to verbally.
8. Performance and Discharge
Principle: The performance of a contract refers to fulfilling all obligations. A contract can be discharged (ended) once both parties complete their obligations, through mutual agreement, or by other legal means.
- Key Points: Contracts can end when obligations are met, one party is released by the other, or certain terms specify termination conditions.
- Example: If a contractor completes a project and the client pays in full, the contract is discharged.
9. Remedies for Breach of Contract
Principle: If one party fails to fulfill their obligations, the other party may seek remedies such as damages, specific performance, or contract cancellation.
- Key Points: Remedies depend on the severity of the breach and can include compensatory damages, restitution, or court-ordered performance.
- Example: If a vendor fails to deliver goods, the buyer may sue for damages equivalent to the cost of sourcing the items elsewhere.
Internal Link: For more on addressing breaches, see our Guide to Creating Custom Clauses.
10. Amendments and Modifications
Principle: Amendments allow for changes to the contract terms if both parties agree. Without a formal amendment process, verbal modifications may not be enforceable.
- Key Points: Include an amendment clause stating that modifications must be in writing and signed by both parties.
- Example: A client and contractor agree to change the project timeline, and they both sign an amendment reflecting the new deadline.
