How Much Does a Social Media Expert Witness Cost?

Social media expert witness fees typically range from $3,000 to $15,000 for initial retainer and report preparation, depending on case complexity, the number of platforms involved, and whether deposition or trial testimony is required. My standard retainer is $5,000, which covers initial case review and report preparation. Deposition and trial testimony are scoped and billed separately.

What Affects the Cost of a Social Media Expert Witness?

Several factors determine what you'll pay to retain a qualified social media expert witness:

Scope of work. A case requiring analysis of a single Instagram account is materially different from one involving cross-platform influencer campaigns, advertising data, and algorithm behavior across TikTok, YouTube, and Snapchat. More platforms and more data means more time.

Stage of engagement. I offer initial consultations at no charge to review case materials and assess fit. After that, fees break into phases: retainer and report preparation, deposition preparation and testimony, and trial testimony — each scoped separately.

Expert qualifications. Practitioners with hands-on platform experience, published work, and a track record of retained cases command higher fees than academics or generalists. For cases involving Daubert challenges, that credibility premium is worth it.

Timeline. Expedited engagements — cases with tight discovery deadlines or last-minute retention — typically carry a premium.

What Does My Retainer Cover?

My retainer covers: initial review of case materials and discovery documents; analysis of platform data, screenshots, analytics exports, and metadata; and drafting of an expert report, declaration, or affidavit. Deposition preparation, deposition testimony, and trial testimony are scoped separately based on actual time required.

Is It Worth Retaining an Expert Early?

Yes — and early retention often reduces your total cost. When I'm involved during discovery, I can help shape subpoenas for platform data, identify what evidence exists before it disappears, and prevent costly mistakes in how digital evidence is collected and preserved. Waiting until the eve of trial typically means higher fees, compressed timelines, and a weaker record.
