Void ab initio

Definition

A Latin phrase meaning 'void from the beginning.' A judgment that is void ab initio is treated as though it never existed because it was entered without proper authority — for example, when a court lacked jurisdiction over the defendant. Unlike a merely erroneous judgment, a void judgment has no legal force at any point.

Examples

• •Petitioner argues the default judgment against Coney Island was void ab initio because the court lacked personal jurisdiction due to improper service.
