👉 Non-customary is a legal term in many countries that refers to something that is not customary or accepted as being right, proper, or fair. It can refer to an act, behavior, or practice that is not recognized by common law principles and is often considered more acceptable than what is commonly accepted. Non-customary practices might include things like using a different language, eating at home instead of in a restaurant, or engaging in activities that are more traditional or less socially acceptable.
