Mobile Forensic Expert Witness Fees & Engagement

Every caller asks the same reasonable question: what will this cost? The honest answer is that it depends on four things — the devices and data sources, the volume and condition of the data, the deadlines, and the deliverable — and those four things are explained below. Engagements are scoped to the matter, and a written estimate is provided after a conflict check, before any work begins.

Cost Factors

What drives the cost of a mobile forensics engagement

There is no standard price because there is no standard matter. Four attributes of the matter — not a rate sheet — determine the scope of the work, and the scope determines the estimate.

Devices and data sources

A single custodian iPhone is a different engagement from six custodians with iPhones, Android devices, iCloud and Google accounts, and years of computer backups. Each additional device, platform, and cloud source adds acquisition, validation, and analysis time — and cloud sources in particular may require separate legal process before they can be collected at all.

Volume and condition of the data

The extraction type matters. A logical extraction — the data the operating system agrees to share — generally parses faster than a full file-system extraction, and deleted-data recovery, which involves reconstructing records from database free space, is more painstaking still. Locked, damaged, or partially wiped devices typically require additional effort before analysis can even begin.

Deadlines and posture

Standard scheduling costs less than expedited work. A matter with an expert-disclosure date weeks away, or an evidentiary hearing already on the calendar, may require the same review and drafting to be compressed into fewer days. Telling us the deadlines up front allows the estimate to reflect the actual posture rather than an assumption.

The deliverable

A consulting memorandum for counsel is a narrower undertaking than a written expert report; a report that must withstand deposition and trial testimony requires the most preparation of all. Each step up in formality — memorandum, declaration, report, deposition, trial — adds drafting, citation, and preparation time, and the estimate is built around the deliverable the matter actually requires.

Roles & Fee Structure

Consulting, testifying, and neutral roles

The role shapes the structure of the engagement, not merely its label. A consulting engagement can often be scoped narrowly and expanded only if the findings warrant it; a testifying engagement must account for disclosure obligations from the outset; a neutral appointment is governed by the appointing order. See our expert witness services and reports & testimony pages for what each role involves.

Consulting expert: An expert retained to advise counsel behind the scenes, whose analysis is generally protected from disclosure as attorney work product. Because nothing need be disclosed, the work can be scoped tightly — a targeted review of an extraction, or an assessment of an opposing report — and expanded only if the matter requires it.
Testifying expert: An expert whose opinions will be disclosed. In federal court, Fed. R. Civ. P. 26(a)(2)(B) requires a written report stating all opinions, the bases for them, and the facts and data considered — which adds report drafting, deposition, and trial preparation to the scope from the beginning.
Court-appointed neutral: A neutral or special master serving the court rather than a party. Fees are typically structured and allocated between the parties under the appointing order, and the scope is defined by the court rather than by either side.

Process

How engagement works

The sequence is deliberate, and it protects the client. No privileged or confidential material changes hands before the conflict check is complete and an engagement agreement is in place — a safeguard for the privilege, not an administrative formality. There is no charge to run a conflict check and receive a written estimate.

Most new matters move through all three steps quickly. Conflict checks run the same day on most new matters, capacity permitting, and expedited engagements are available where disclosure or hearing deadlines require them.

What Happens Next

01
Conflict check
Same-day on most new matters, capacity permitting. We confirm there is no conflict before anything privileged is shared.
02
Scoping call & written estimate
A brief discussion of the devices, data, deadlines, and deliverable — followed by a written estimate before any work begins.
03
Engagement letter & secure transfer
With the engagement letter signed, materials are transferred over a secure channel and the review begins.

FAQ

Frequently asked questions

How much does a mobile forensic expert witness cost?

Engagements are scoped to the matter, so there is no standard price. Fees depend on the number of devices and data sources, the volume and condition of the data, the deadlines, and the deliverable — a consulting memorandum is a narrower undertaking than an expert report followed by deposition and trial testimony. After a conflict check and a brief scoping call, we provide a written estimate before any work begins.

Do you charge for the initial conflict check?

There is no charge to run a conflict check and receive a written estimate. Please do not send privileged or confidential materials until the conflict check is complete and an engagement agreement is in place.

Can you work within a litigation budget?

In many matters, yes. The most effective control on cost is scope — limiting the analysis to the devices, data sources, and questions the matter actually requires. Where budgets are constrained, work can often be phased: an initial assessment first, with further analysis only if the findings warrant it. The written estimate reflects the scope counsel selects.

How quickly can an engagement start?

We run conflict checks the same day on most new matters, capacity permitting. Once the scoping call is complete and the engagement letter is signed, work can begin promptly. We accept expedited engagements where disclosure or hearing deadlines require it.
