Lying by omission isn't inherently a crime in everyday life, but it becomes illegal (criminal or civil) when there's a legal duty to disclose information, such as in contracts, court (perjury), or to federal agents (false statements), leading to charges like fraud, perjury, or false statements if it's material and intended to deceive or harm.
