Reasonable steps taken by a person or company to satisfy a legal requirement, especially in buying or selling something; a comprehensive appraisal of a business undertaken by a prospective buyer, especially to establish its assets and liabilities and evaluate its commercial potential.

It's a critical investigative process before entering into a contract or transaction, ensuring all risks and opportunities are understood.

The story behind the word. The phrase 'due diligence' comes from legal English, where 'due' means 'proper' or 'adequate,' and 'diligence' comes from the Latin 'diligentia,' meaning 'care, attentiveness.' So, it literally means 'proper care' or 'adequate attentiveness.' It describes the careful and thorough investigation that a prudent person or company would undertake before making a significant decision or entering a contract.
