The Latin term Lis Pendens refers to a pending legal action or lawsuit. It means "a suit pending," indicating that the case is under consideration by the court. The other terms, such as Per Incuriam (decisions made without proper legal consideration) and Caveat Emptor (let the buyer beware), are not related to pending legal actions. Res Judicata refers to a matter that has already been judged.
Thus, the correct answer is Lis Pendens.
