What is eDiscovery: How to Do it & Pro Tips for 2025
eDiscovery involves identifying and producing electronically stored info relevant to legal cases.
Common challenges include preservation failures, scope creep, and format compatibility issues.
Proper eDiscovery handling is crucial to avoid sanctions, missed deadlines, and lost cases.
Best practices involve clear scoping, data testing, rigorous security, and maintaining data custody.
Choosing an eDiscovery tool involves simplicity, integration, security, scalability, and strong support.
If you’ve ever felt overwhelmed by the sheer volume of digital data involved in legal matters, you’re not alone. It’s a very common legal tech ops problem. Navigating eDiscovery can feel like wrangling a chaotic inbox on a deadline, especially when the stakes are high.
Over the years, I’ve helped firms of all sizes streamline their eDiscovery processes with practical systems, tested tools, and a little bit of upfront planning. In this guide, I’ll walk you through exactly what eDiscovery is, why it matters, and how to manage it without losing your sanity (or your case).
What is eDiscovery for Law Firms?
eDiscovery (AKA electronic discovery or e-discovery) is the process of identifying, collecting, and producing electronically stored information (ESI) in response to a request for production in a lawsuit or investigation. This includes things like emails, texts, social media content, documents, spreadsheets, and/or databases. If it’s stored digitally and could be relevant to a legal matter, it’s in scope.
In my experience, the key to managing eDiscovery well is having a clear process in place. That means knowing where client and firm data is stored, setting up systems that preserve information properly (including the metadata), and having the right tools and vendors to assist when things get complex.
Finally you will need to give some thought to indexing the monsoon of digital information you will get. Sifting through 80GB of emails 2 days before a trial or deposition leads to late night caffeine and whatever fallout that causes you.
Why is eDiscovery Important?
eDiscovery is critical because most business communication and records are now electronic. Whether you're handling litigation, responding to a subpoena, or preparing for arbitration, the relevant information is more likely to be found in someone's inbox or cloud storage than in a filing cabinet. Your company, Law firm, and/or clients company generates a LOT more data that may be relevant that you initially realise. An email can also contain the metadata of when the email was sent, where geographically it was sent, was it sent over a laptop or email, etc.
Failing to manage eDiscovery properly can lead to serious consequences—sanctions, missed deadlines, or even losing a case because of spoliation or failure to disclose. I’ve seen how a well-prepared firm can avoid these pitfalls and even gain strategic advantage by being on the front foot with eDiscovery.
It’s also about trust. Clients expect us to protect their data and handle it professionally. Courts expect us to be diligent and thorough. If we don’t meet those expectations, it affects our credibility.
The Most Common eDiscovery Challenges
From what I’ve seen, most eDiscovery issues fall into a few predictable categories:
Preservation Failures
Someone didn’t issue a litigation hold, or IT deleted data too early. That’s avoidable with the right protocols.
Just about every major infrastructure solutions provider on the planet have some kind of Lit hold feature. The Microsoft Office 365 platform and G Suite platforms have very comprehensive ones that allow you to freeze inbox, snapshot file directories and track changes with dates and times. Any IT Admin worth their salt will have some kind of comprehensive backup and retention policy in place however if you are unsure of what this is in your or your clients company you will have to get it and ensure that it is documented.
Most Vendors by default back up 1 year of data, however the legal obligation is typically between 5 and 7 years, so you will want to ensure that this is correctly set up.
If possible request access to this, if only temporarily, in order to run some test queries and see how your platform works. When requests for discovery are asked of you or your firm, knowing how the tool works and what it returns for certain requests will help you understand the scope limitations you have to work with.
Scope Creep
Without tight definitions and early case assessments, eDiscovery can balloon out of control, both in cost and in data volume.
Once you have an idea of how your tool works and the data it produces from your own testing you will have a good idea of how to tighten your scope requests to your opposition. In the modern business asking for broad terms like any piece of DATA, because ultimately that is what you are asking for and that is what is going to be returned, can return all results ranging from emails and messages, articles to things like credit card payment receipts that have that persons name on.
Format and Compatibility Problems
You get data that you can’t open or search properly. That slows everything down and increases costs.
Once you are able to appropriately tie your scope down to what is actually useful to you and your case you will need to find a way to properly index it. As with all things legal preparation is key, in this case your preparation is your scope request. What you get back will need to be categorized and indexed so that you can easily search for key data points. There are a million e-discovery tools on the market and finding one that suits your firms “style” is always going to be tricky, using something like sharepoint or googledrive will automatically table this information so that it is filterable at a basic level. With recent built in AI additions to those tools you may even be able to adequately search the documents for information you need.
Privilege and Confidentiality Errors
Accidentally producing privileged or sensitive material is a big risk. I always double-check redactions and rely on review tools with solid privilege detection.
How you manage privileged information and confidentiality are the underlying key to your credibility as a professional. You will inevitably receive information during discovery that may not be useful or directly related to your case. It may involve other people and their lives unrelated to the case or work. You have a moral, ethical and professional responsibility to parse through the information you receive and carve out the bare minimum that you need and no more. You will also give this kind of material to others when you receive requests, either knowingly or unknowingly, it happens.
Before sending anything, check your redacted information, check the level of access that the receiving party (internal or external) is allowed to have, and then have someone else confirm it back to you. In the event of a miscommunication, always err on the side of caution and work towards the most secure option. You can always unredact and send a little bit more; however, you cannot get the cat back in the bag, proverbially speaking.
Cost Overruns
eDiscovery can get expensive fast, especially with large data volumes or if outside vendors are involved. Having a budget and tracking tool helps keep things under control.
Data storage is becoming cheaper; however, you will be surprised how much it can cost when 1TB of information is dropped on you to store for 5 years. We have all made a long-distance call without releasing it or been a bit too generous at a bar with our credit cards. The last thing you want is an unexpected data bill from your e-billing provider at the end of the year, and have to return to a client with an unexpected invoice, that's bad for business. Treat your budget here like a risk; determine what your appropriate budget appetite is, and then add 10% as a safety net.
Regularly check your usage and the accrued budget expense so far; this will help you determine your efficiency. Obviously, this won't be “billable time,” however, it will help you retain your professional integrity and be more efficient with your time.
My Top 4 eDiscovery Best Practices
My best practises are relatively simple:
1. Scope: Identify EXACTLY what you are being asked for, or asking. File formats, types of data (emails, IM’s, social media posts) and date ranges as well as key words. Be as specific, or broad as you need to be.
2. Test: with your scope in mind test, on your own platform, those parameters to see what data is returned. This will help you identify either the amount of data you need to transmit or that you are about to receive and sift through.
3. Security: The integrity of the information you send says a lot about you as a firm, remember there are going to be a lot of eyes on whatever you send, opposition counsel, judges, juries, tribunals, people on the internet randomly looking for things to try and break down on tik tok. Treat the information personally.
4. Custody: You need a chain of custody for every piece of information, who has handled it, where it came from, when it has been viewed and by whom. Has it been edited? Is this the original? How was this information generated?
Current Electronic Discovery Reference Model (EDRM)
The current EDRM (Electronic Discovery Reference Model) represents a standardized framework that outlines the stages of the eDiscovery process used in legal, compliance, and regulatory environments to manage electronically stored information (ESI).
Here’s a breakdown of the modern EDRM model as updated and maintained by the EDRM organization (most recently refreshed in 2023):
1. Information Governance
Goal: Set policies to manage ESI before litigation
Actions: Data mapping, retention planning, compliance controls
2. Identification
Goal: Find relevant data sources and custodians
Actions: Scope matters, locate cloud/email/chat sources
3. Preservation
Goal: Safeguard data from alteration or loss
Key Actions: Apply legal holds, lock data, log access trails
4. Collection
Goal: Gather ESI while maintaining integrity
Actions: Forensic imaging, maintain chain of custody, extract files
5. Processing
Goal: Reduce data volume and prep for review
Actions: De-duplicate, normalize formats, extract metadata
6. Review
Goal: Assess documents for relevance and privilege
Actions: Cull, redact, tag, use AI-assisted review (TAR)
7. Analysis
Goal: Uncover facts, patterns, and relationships
Actions: Build timelines, map communications, visualize data
8. Production
Goal: Deliver responsive ESI in usable formats
Actions: Convert to PDF/TIFF/Native, apply Bates, create load files
9. Presentation
Goal: Present ESI in court or proceedings
Actions: Prep exhibits, organize deposition materials
Find & Using eDiscovery Solutions
Over the years, I’ve learned that choosing the right eDiscovery solution isn’t about chasing the latest tech, it's about finding a tool or partner that fits how your firm actually works. There are plenty of platforms out there that promise everything from AI review to predictive coding, but if your team can't use it efficiently, it's not helping.
When I'm evaluating eDiscovery tools, I apply the same law firm management principles and look for a few key things:
- Ease of Use: If the interface is clunky or overly technical, my team won’t adopt it. Simplicity wins.
- Integration with Existing Systems: The solution needs to work with our email archiving, case management, and document storage platforms.
- Security: We’re dealing with sensitive client data, so encryption, access controls, and compliance certifications (like ISO 27001 or SOC 2) are non-negotiable.
- Scalability: Whether it's a small employment matter or a massive commercial dispute, the platform should handle both ends of the spectrum.
- Support and Training: Good vendor support can make or break a project. I prefer providers who offer onboarding help and quick responses when issues come up.
Once we’ve chosen a solution, I work closely with IT, legal teams, and sometimes external consultants to implement it properly. We train our staff, run test cases, and document workflows so that everyone knows what to do when a matter arises.
And just as importantly, I revisit our tools regularly. What worked three years ago might not be the best fit today. Staying proactive about our tech stack means we stay efficient, compliant, and competitive.

eDiscovery FAQ
Here are some questions people also ask me about eDiscovery processes and solutions:
What is an eDiscovery job?
An eDiscovery job involves managing electronic data during litigation. It’s not just reviewing documents, it includes identifying, preserving, processing, and reviewing digital evidence. In my experience, these roles require both legal knowledge and tech skills to ensure compliance, reduce risks, and streamline discovery.
Who uses eDiscovery?
Law firms, corporate legal teams, and government agencies all use eDiscovery. I use it in nearly every litigation matter. Whether internally or with outside vendors, anyone handling electronic evidence is relying on eDiscovery processes to manage risk and meet legal obligations.
What is ESI?
ESI means Electronically Stored Information, emails, texts, documents, metadata, and more. Managing ESI properly is critical. I’ve seen cases hinge on how well data was preserved or produced, and courts don’t go easy when digital evidence is mishandled.
What does an eDiscovery consultant do?
eDiscovery consultants guide legal teams through the technical side of managing ESI. They help with data collection, filtering, and review tools. I often bring them in on complex cases, they help us stay efficient, avoid mistakes, and comply with court rules.
What is the NIST list in eDiscovery?
The NIST list refers to data destruction standards from NIST 800-88. In eDiscovery, it helps show we handled sensitive data securely, especially when deleting non-responsive or privileged info. Following it helps us avoid challenges over data handling.
What is the difference between discovery and eDiscovery?
Discovery covers all info exchange in litigation. eDiscovery focuses just on electronic data. While the goals are the same, eDiscovery involves different tools and risks. I treat it as its own discipline, it’s too complex to lump in with traditional discovery.
What do legal professionals do in the legal process of eDiscovery?
Legal professionals guide the legal process in each legal case, ensuring compliance with the federal rules of civil procedure. In legal proceedings, they manage how ESI is handled so relevant evidence is collected lawfully.
What electronic documents are used in eDiscovery?
Electronic documents, electronic information, instant messages, relevant ESI, and paper documents are all common in eDiscovery. These data types are preserved and processed to create a complete evidence record.
How is data collected and analyzed in eDiscovery?
Teams collect data from multiple sources, use data analysis to find relevant evidence, and apply data management to preserve metadata. Deletion protocols and handling large volumes of data are also key steps.
What is digital forensics in eDiscovery?
Digital forensics ensures evidence integrity, supports document review, fulfills ediscovery requests, and manages the review process. It verifies data is unaltered and maintains the chain of custody.
