The CJA voucher Expert Agreement Form is a legal document created by the United States Courts to facilitate the payment of expert witness services in criminal justice act (CJA) cases. CJA voucher Expert Agreement Forms are used by the courts to document the agreement between the court and the expert witness regarding the fee for services. The form contains the contact and payment information of both parties, the services to be provided, the fee amount, and any special terms and conditions of the agreement. There are two types of CJA voucher Expert Agreement Forms: an independent expert agreement form and a court-appointed expert agreement form. The independent expert agreement form is used for witnesses who are not court-appointed. The court-appointed expert agreement form is used for court-appointed witnesses. Both forms must be completed and signed by both parties in order to be valid.
