A quick definition of nonvital term:

A term is a word or phrase that has a specific meaning in a certain field or a condition that is agreed upon in a contract. A fundamental term is an essential part of a contract, while a nonfundamental term is not as important. An implied term is not specifically stated in a contract but is understood to be included. A material term deals with significant issues such as price or quality. A term of years is a fixed period of time, and a term of court is the period during which a court conducts judicial business. There are different types of terms, such as general terms, special terms, and appearance terms. In English law, a term fee is a sum that a solicitor may charge a client for each term in which legal proceedings take place.
