What is the relationship between custom customary law and the rules of common law and equity?

Customary law refers to traditional norms and practices that govern behavior within specific communities, often operating alongside formal legal systems. Common law and equity are formal legal systems that originate from judicial decisions and principles, emphasizing consistency and fairness. While common law is based on precedent and statutory interpretation, equity seeks to address situations where strict application of the law would result in injustice. The relationship between these systems can be complex, as customary law may influence the development of common law and equity, particularly in jurisdictions that recognize and incorporate local customs into their legal frameworks.
