1. Bilateral vs. Unilateral Contracts

Contracts can be broadly categorized into bilateral and unilateral contracts:

  • Bilateral Contracts: Both parties exchange mutual promises. Most common contracts fall into this category.
  • Unilateral Contracts: One party promises something in return for the act of the other party.

Examples

Bilateral Contract: I will sell you my car for $5,000. You agree to pay $5,000 for my car.

Unilateral Contract: I will pay $100 to anyone who finds and returns my lost dog.

2. Express vs. Implied Contracts

Contracts can also be classified as express or implied:

  • Express Contracts: Clearly stated terms, either written or spoken.
  • Implied Contracts: Formed by the actions or conduct of the parties.
Note: Implied contracts are just as legally binding as express contracts.

3. Executed vs. Executory Contracts

Contracts can further be divided based on their performance:

  • Executed Contracts: Both parties have fulfilled their contractual obligations.
  • Executory Contracts: Some or all obligations are yet to be performed.

4. Valid, Void, and Voidable Contracts

Based on their enforceability, contracts can be:

  • Valid Contracts: Legally binding and enforceable.
  • Void Contracts: Not enforceable by law.
  • Voidable Contracts: Valid contracts that can be rejected by one party.
