Ignorantia Facti Excusat: A Comprehensive Guide to Legal Excuses

Q: What is the difference between ignorance of fact and ignorance of law?

Ignorance of fact can excuse actions, while ignorance of law cannot.

Q: How can I prove ignorance of fact in a legal dispute?

You will need to provide evidence that shows your misunderstanding was genuine and significant.

Definition & Meaning

Ignorantia facti excusat is a legal principle that translates to "ignorance of fact excuses." This means that if a person acts under a misunderstanding of a significant fact, their actions may be excused. For example, if someone enters into a contract based on incorrect information about a key aspect of that contract, they may have grounds to void the agreement. However, it's important to note that ignorance of the law itself does not serve as an excuse.
