A number of delivery models for legal aid have emerged. In a "staff attorney" model, lawyers are employed on salary solely to provide legal assistance to qualifying low-income clients, similar to staff doctors in a public hospital. In a "judiciary" model, private lawyers and law firms are paid to handle cases from eligible clients alongside cases from fee-paying clients, much like doctors are paid to handle Medicare patients in the U.S. The "community legal clinic" model comprises non-profit clinics serving a particular community through a broad range of legal services (e.g. representation, education, law reform) and provided by both lawyers and non-lawyers, similar to community health clinics.
