Express terms

Express terms are specifically agreed parts of a contract.  Implied terms are not specifically agreed but implied by the courts or Parliamentary acts.

Express terms to a contract can be agreed to either orally or in writing.

Written terms cause 3 problems:

1. Can the court go beyond the written contract to discover additional terms?
2. Is someone bound by written terms?
3. Can written terms be incorporated into a contract by notice or in the course of dealings?
