This document introduces a training course on construction contract laws. The first module defines what makes an agreement a legally binding contract. An agreement is only a contract when it is enforceable by law. To be enforceable, an agreement must comply with all relevant laws of the country, including acts, statutes, judicial precedents, and principles of equity and natural justice. Understanding how agreements become enforceable contracts through law is the first step to grasping construction contract laws. Future modules will cover topics like stare decisis, case law, and how to interpret and challenge arbitration awards.
