Independent technical practice

Digital evidence for litigation

Evidence that survives the other side’s expert. Court-qualified examiners preserve it, examine it and explain what it shows.

Exposure

Where cases go wrong

Most disputes now turn on records that were never written to be evidence: chat threads, collaboration histories, mobile backups, cloud audit logs and telemetry from systems that overwrite themselves on a schedule. The window in which those artifacts can be preserved is frequently shorter than the window in which a matter is assessed.

The second exposure is process rather than data. Collections performed by an in-house IT team, a self-collecting custodian or an unqualified vendor invite challenges to authenticity, completeness and chain of custody. Opposing counsel can challenge a weak method far more easily than the substance of the evidence.

The third is the arrival of synthetic media and AI-assisted content in the record. Audio, video, images and documents can now be generated or altered convincingly enough that authenticity must be tested rather than assumed, and the testing has to be documented in a form a court can weigh.

Scoping

Questions the engagement must answer

  1. What evidence exists, where does it live, and how quickly is it degrading?
  2. Can the collection be repeated by the other side’s expert and reach the same result?
  3. Which findings are observed fact, and which are expert interpretation?
  4. What does the evidence not show, and what would it take to resolve that?
  5. What form do exhibits need to take for this filing, this court, this deadline?

How we help

Context

Regulatory and evidentiary context

Federal Rule of Evidence 702 / Daubert
Expert opinion is admitted on the reliability of the method and the qualification of the examiner, so we document method, tooling and limitations in a form that can be examined line by line.
Authentication
Digital records have to be shown to be what they are claimed to be, which is a question of acquisition, hashing and chain of custody long before it is a question of content.
Spoliation and legal hold
Once litigation is reasonably anticipated, routine deletion becomes a liability; we advise on hold scope and preserve first so the question never has to be argued.
Privilege and work product
Engagements can be structured through outside counsel where the analysis is intended to sit inside privilege.

Context only. Counsel determines which standard governs the matter, and we write to the standard the forum applies.

What the technical record can answer

The distinctions and deliverables that matter when digital records enter a dispute.

Forensics is not data recovery, and not eDiscovery

Data recovery restores data after a physical failure. eDiscovery produces what was requested from identified custodians. A forensic examination goes further: slack and unallocated space, hidden and system files, artifacts left by the operating system, and file date codes showing when material was created, modified, accessed or deleted. That is where evidence that no one produced tends to sit.

What counsel gets back

Enterprise matters may require extraction from databases and mail servers and reconstruction of events from the resulting artifacts. The deliverable is a concise written report using accepted methodology, scoped to the questions in the matter, and defensible when the method itself is challenged.

Support for investigators

Investigators working a matter can retain examination capability without building a laboratory: email, images, phone logs, transactions, browsing history and social artifacts, including material deleted or hidden, recovered and documented so it survives the same scrutiny as the rest of the file.
