A paralegal, also known as a legal assistant, or paralegal specialist is a legal professional who performs tasks that require knowledge of legal concepts but not the full expertise of a lawyer with an admission to practice law. The market for paralegals is broad, including consultancies, companies that have legal departments or that perform legislative and regulatory compliance activities in areas such as environment, labor, intellectual property, zoning, and tax. Legal offices and public bodies also have many paralegals in support activities using other titles outside of the standard titles used in the profession. There is a diverse array of work experiences attainable within the paralegal field, ranging between internship, entry-level, associate, junior, mid-senior, and senior level positions.

A law clerk, judicial clerk, or judicial assistant is a person, often a lawyer, who provides direct counsel and assistance to a lawyer or judge by researching issues and drafting legal opinions for cases before the court. Judicial clerks often play significant roles in the formation of case law through their influence upon judges' decisions. Judicial clerks should not be confused with legal clerks, court clerks, or courtroom deputies who only provide secretarial and administrative support to attorneys and/or judges.
