Definition - What does Attorney's Lien mean?
An attorney's lien is a financial lien that is placed by an attorney against a client who has not paid for their legal services for the purpose of forcing the client to pay. It is a lien in the same sense as any normal person takes a lien against another, but is with respect to legal fees only.
Justipedia explains Attorney's Lien
An attorney would have to satisfy all of the normal conditions brought about by law when placing a lien on a client's property including first trying normal recourse methods for payment of fees and services rendered including going through collection methods.
