1.1.1 Types of Contracts

  1. Express contract– The terms are stated orally or in writing.
  2. Implied contract– Some terms may be logically inferred. Example: You sign a consulting contract with a client. Although not specifically stated, it is assumed you won’t show up drunk at the client’s premises.
  3. Executed contract– A contract which has been completed.
  4. Executory contract– An incomplete contract.
  5. Unilateral contract– One party makes a promise contingent on another party’s actions. The other party accepts or rejects based on performance or non-performance. Example: I offer you $20 to mow my lawn. If you take up my offer, I am obliged to pay you.
  6. Bilateral Contract– Each party makes a promise to do something. Example: You agree to design my company’s website for $1,000.

In many cases, a contract may be written or oral. In some cases, a written contract is required. This topic is covered later in these notes.
