Retired Judge Greg Holder’s 2022 Hourly Expert Witness or Special Magistrate Rates: $450 per hour


Multi-Day hearings: The significant number of cases being set on our calendar for final hearings has necessitated our need to require a non-refundable deposit at the time of scheduling a final multi-day proceeding.  The scheduling and cancellation of these matters have impacted our ability to calendar other proceedings.  Consequently, we have deemed it necessary to require an eight (8) hour non-refundable deposit be paid at the time of scheduling a final hearing of greater than two (2) days duration. For every day more than two (2) days scheduled, an additional four (4) hour deposit will be required. We will hold your scheduled hearing on our calendar for seven (7) days.  Should the required non-refundable deposit not be received, we will release the hold.  Of course, you will be credited for the full amount of the non-refundable deposit on any invoice submitted for the actual final hearing. Written notice of cancellation of the hearing must be received, by our office, via e-mail or Fax.  If any hearing of three (3) days or less is cancelled within ten (10) calendar days of the hearing, the cancellation fee is $1,000.00 plus payment of any preparation time. 

Half or Full Day hearings: If the hearing is cancelled (whether agreed to by the parties or unilaterally by one party) within seven (7) business days of the scheduled date, a minimum of two (2) hours will be billed to the client/parties at the applicable hourly rate (dependent on the number of parties) for a half day hearing, and a minimum of four (4) hours will be billed to the client/parties at the applicable hourly rate (dependent on the number of parties) for a full day hearing. For example, if your hearing is scheduled for Wednesday, you must notify our office of the cancellation by close of business the prior Tuesday to avoid any cancellation charges.

Half or Full Day hearings: If the hearing is cancelled (whether agreed to by the parties or unilaterally by one party) within three (3) business days of the scheduled date, the client/parties will be billed at the applicable hourly rate (dependent on the number of parties) for the full amount of time scheduled plus preparation time. For example, if your full day hearing is scheduled to begin on Wednesday, and the parties cancel at any time on prior Friday, the client/parties will be billed for eight (8) hours at the applicable hourly rate (dependent on the number of parties) plus preparation time. Likewise, if your half day hearing is scheduled to begin on Wednesday, and the client/parties cancel at any time on prior Friday, the client/parties will be billed for four (4) hours at the applicable hourly rate (dependent on the number of parties) plus preparation time.

Any cancellation fee will be billed to the client/parties and each client/party will be required to pay their respective share of the cancellation fee.  We would especially appreciate you advising your clients of these financial matters in advance of the proceeding. 


Hearings may be held at any location, or virtually using Zoom if approved by the Court or agreed upon by all parties. If the parties cannot reach any agreement regarding physical location, then the hearings will be held at either the offices of Zinober Diana & Monteverde, P.A. or at a court reporter’s office selected by Retired Judge Greg Holder, in the county where the matter is pending. There are no travel fees for cases in Hillsborough, Pinellas, or Pasco Counties. Travel outside of these counties will be billed at the rate of $125 per hour.
