Black's Law Dictionary
This term generally denotes any form of service of process other than personal service, such as service by mail or by publication in a newspaper; but it is sometimes employed to denote service of a writ or notice on some person other than the one directly concerned, for example, his attorney of record, Who has authority to represent him or to accept service for him.
