Sworn and court-certified expert witness

Clarity in
disputes.

As an expert witness for online marketing, I support cases of uncertainty and dispute with well-founded reports on services, costs and results.

Who I work for

  • 01

    Courts

    Reports commissioned by the court.

  • 02

    Law firms

    Private reports for assessing and preparing proceedings.

  • 03

    Public authorities

    Expert assessment of digital services and procurement.

  • 04

    Companies

    Resolving disputes with agencies and service providers – also out of court.

Typical questions

What reports are often about

  • Were the agreed online marketing services delivered completely and professionally?
  • Are fees, media budgets and billed hours traceable and reasonable?
  • Does a website, shop or campaign meet the state of the art?
  • Were reach, rankings or metrics reported correctly?
  • What damage resulted from errors or outages in online marketing?

How a court-appointed report works

  1. Appointment

    The court or public prosecutor appoints the expert from the official register. I check the subject matter and my impartiality and flag likely high costs in advance.

  2. Findings

    Establishing the facts: analysis of documents, data, ad accounts, websites and tracking. The parties are involved to preserve their right to be heard.

  3. Report

    Expert conclusions are drawn from the findings. The written report answers only the technical questions of the court – without legal assessment.

  4. Hearing

    Oral explanation at the hearing and answers to supplementary questions from the court and the parties.

  5. Fees

    Fees are claimed from the court under the Austrian Fee Entitlement Act (GebAG). The court decides who bears the costs.

Private expert reports

For law firms, companies and authorities I also prepare reports outside court proceedings. Questions, scope and fees are agreed in writing in advance.
