Commentary

'Must' is used to convey compulsory duties or requirements in legal drafting; it is stronger than 'should' but less formal than 'shall' in some jurisdictions.

This glossary is for general informational and educational purposes only. Definitions are jurisdiction-agnostic but reflect terminology and concepts primarily drawn from English and American legal traditions. Nothing herein constitutes legal advice or creates a lawyer-client relationship. Users should consult qualified counsel for advice on specific matters or jurisdictions.
