To say that equity seeks to assist the law rather than create it implies that equity is not a form of law on its own. For many years, the argument about the relationship between common law and equity has created a highly polarized situation in the academic world of law. There are those that believe that equity and common law can be combined, those that disagree with this position and those that identify the two as entirely different from each other.
Common law is not written in one document like an act of parliament, however, it is a form of law that is based on previous court cases that are decided by judge. The law is often applied by reference to those previous cases, so common law is also said to be based entirely on precedent.
