The legal principle "ignorantia juris non excusat" translates to "ignorance of the law excuses not," meaning individuals are expected to know the laws applicable to them.
This foundational concept exists in many legal systems worldwide.
In the US, ignorance of the law is a defense in very limited circumstances, primarily when a person could not reasonably know about a law because it was not adequately published or is fundamentally confusing.
Historically, the maxim has roots in Roman law, where it was essential to maintain a society where laws were generally known to ensure fair justice and personal responsibility.
Some jurisdictions have specific statutes that negate the "ignorance" defense, but for most laws, claiming ignorance is largely ineffective in court, underscoring the importance of legal literacy.

In some countries, laws exist that may expressly state ignorance is a valid defense, emphasizing local legal traditions and the necessity of public awareness of such laws.
