Amendment
Amendment: A change to a pleading after it has been filed.

What amendment means
In short, amendment is a term you will meet in court papers, rules and legal research. The definition above gives its usual meaning in American civil practice. However, the exact meaning can depend on the rule, statute or court decision that uses it. So it helps to read the term in context.
Where amendment comes up
For example, the term appears in these procedures:
- Motion for Leave to Amend a Pleading (Fed. R. Civ. P. 15(a)): a request for permission to change a pleading when amendment is no longer allowed as a matter of course.
How to research the term
Start with the primary source. For example, if amendment appears in a federal rule, read the rule itself and its official notes. After that, check your court’s local rules and any standing orders from the judge. In addition, search recent decisions from your own state or federal district. They show how courts read amendment in practice. Because state rules often differ, our state procedures guide links to each state’s official rules. Above all, make sure the version you read is still in force.
