Due diligence
Definition
The investigation a reasonable person or business undertakes before entering a transaction, to verify facts and identify risks. In some statutory contexts it is also a defence, where the defendant shows they took all reasonable precautions.
In plain English: Checking carefully before you commit — and, in some laws, being able to prove you checked.
