The following checklist is for both the propounding and responding party in any matter involving electronic discovery.

  • Prevent data from being damaged or destroyed.
  • Safely extract relevant data.
  • Preserve the chain of custody.
  • Avoid business disruption.
  • Preserve appropriate privileges.


2. Qualifying the expert

  • How many hours of formalized forensic training?
  • EnCE certified or comparable?
  • Number of cases investigated and frequency?
  • Types of cases?
  • Times testified?
  • Investigation training?
  • Background?


3. What to communicate to the forensic expert witness?

  • What exactly you are looking for and trying to accomplish?
  • Case type
  • Names of parties and potential witnesses
  • Existing evidence to support case
  • Possible evidence location(s)
  • Key words
  • Events timeline
  • Output format


4. What can an expert accomplish?

  • Recover deleted, hidden, and temporary files.
  • Find "timeline" evidence: when a file was created, modified, last accessed.
  • Find proof of evidence/document destruction.
  • Provide Web and user activity.
  • Password cracking and recovery.

  • Do check out the expert's credentials.
  • Do prepare your expert for testimony.
  • Don't put off hiring your expert.
  • Don't wait for the opposition to bring out weak points in your expert's report.


6. Will you get the data

  • Is it reasonably obtainable?
  • How specific is the request?
  • What is the likelihood of success?
  • Availability of other sources?
  • Does the benefit outweigh the burden?
  • Purpose of the data (day to day vs. emergency backup)?
  • Cost to gather the data?
  • Resources available to requesting party?


7. How to get the data

  • Send preservation letter.
  • Take the deposition of the person most knowledgeable.
  • If possible, agree on inspection protocols.
  • Expressly request electronic documents.
  • Narrow the request for electronic documents.
  • Focus on the probative value of the information.
  • Specify the production format.
  • Know the technology that is being used to store and retrieve the target documents.


8. How to respond to an electronic discovery request

  • Take responsibility for the relevant documents.
  • Immediately locate and preserve all computer-based evidence.
  • Document evidence-preservation efforts.
  • Evaluate (jurisdiction issues, specificity of request, volume and location of data requested).
  • Limit production by key words, dates, active data.
  • Extract relevant data into a designated folder.
  • Object to it as burdensome, overly broad, and cost prohibitive.


9. Cost shifting—Who should bear the cost?

  • The extent to which the request is specifically tailored
  • The availability of such information from other sources
  • The total cost of production, compared with the amount in controversy
  • The total cost of production, compared with the resources available to each party
  • The relative ability of each party to control costs and its incentive to do so
  • The importance of the issues at stake in the litigation
  • The relative benefits to the parties of obtaining the information. See Zubulake v. UBS Warburg, 217 F.R.D. 309 (S.D.N.Y. 2003) FA
