What does due diligence mean?

Due diligence most generally means reasonable care and caution or the proper actions that a situation calls for, especially those that help to avoid harm or risk.

Due means “proper” or “required.” In legal contexts, diligence means “the degree of care required in a given situation.” In this way, due diligence is the level of care or caution that a specific situation calls for.

Due diligence is especially used in legal and business contexts involving buying, selling, or giving professional advice. This kind of due diligence is often required by law in order to prevent liability.

The phrase due diligence can also refer to the process of researching or disclosing pertinent information before entering into a contract or deal.

For example, in the sale of a house, due diligence on the part of the seller involves disclosing information about the house, such as major problems and the dates when repairs were made. The buyer performs their due diligence by gathering this information and making the proper inspections of the house before the purchase.

It can also be used in more general contexts, as in Don’t believe everything you read on the internet—do your due diligence and fact-check anything that sounds fishy.

The phrase is often used with the verbs perform and do.
