A more thorough explanation:

Definition: An extrajudicial confession is when someone admits to a crime outside of a court of law or legal proceeding.

For example, if someone confesses to a crime to a friend or family member, that would be considered an extrajudicial confession. Another example would be if someone confesses to a crime to a police officer before being read their Miranda rights.

These examples illustrate the definition because they both involve someone admitting to a crime outside of a legal proceeding. This type of confession can be used as evidence in court, but it is important to note that it may not always be reliable as it is not given under the same circumstances as a confession made in court.
