How to Overcome 7 eDiscovery Challenges with Actionable Solutions

The growth of electronically stored information (ESI) has transformed litigation and regulatory investigations, but it has also introduced complexity, rising costs, and operational risk. eDiscovery now represents one of the most resource-intensive components of legal workflows. In fact, U.S. eDiscovery spend is projected to exceed $40 billion annually, with document review accounting for more than 80% of total litigation costs.

To manage this environment effectively, organizations must address seven persistent challenges head-on. Below, we outline the most common obstacles and the strategies that help overcome them.

1. Data Volume and Complexity in eDiscovery

The Challenge

Litigation increasingly involves massive volumes of data across diverse formats—emails, documents, chat platforms, social media, and mobile devices. A recent survey found that 60% of litigation support directors say that the continued growth of case data volume is a challenge for their teams.

The Solution

Reducing volumes early is critical and so is identifying key custodians and collecting from only relevant sources, which helps streamline review. In addition, Technology-Assisted Review (TAR) and predictive coding prioritize relevant documents and reduce manual workloads. Other solutions include using data culling and scalable eDiscovery platforms. Data culling techniques such as keyword searches, date filters, and custodian filters, further limit irrelevant material, while  scalable eDiscovery platforms ensure the infrastructure can handle large, varied datasets efficiently.

2. Scattered Data Locations

The Challenge

Relevant data is often dispersed across local drives, servers, cloud platforms, mobile devices, and social media. Fragmentation makes it difficult to create a complete and defensible record.

The Solution

Establishing clear data storage policies supports easier identification and preservation. It is also key to leverage centralized data management and archiving solutions, as they improve visibility and control. Finally, modern eDiscovery platforms with multi-source collection capabilities and AI-powered search can be used to help manage fragmented datasets while maintaining integrity.

3. Data Privacy and Security Issues

The Challenge

Sensitive information, including personal and confidential business data, is highly vulnerable during collection, transfer, and review. Compliance with frameworks such as GDPR and CCPA requires strict safeguards.

The Solution

There are several ways to tackle this challenge. First off, robust encryption, access controls, and secure communication channels protect data throughout the process. Then, there are regular audits and monitoring solutions, which strengthen oversight. This is best coupled with recurring employee training, which reduces the risk of accidental breaches. Lastly, partnering with eDiscovery providers that hold strong security certifications ensures consistent adherence to best practices when it comes to evading privacy and security issues.

4. Rising Costs

The Challenge

Expanding volumes, manual review, and outdated practices drive costs upward. Document review alone consumes the majority of litigation budgets. In fact, eDiscovery costs in the US are estimated to reach$40 billion annually, with document review accounting for over 80% of total litigation spend.

The Solution

Early Case Assessment (ECA) reduces unnecessary review by culling irrelevant data upfront. TAR and advanced analytics automate document review and accelerate relevance determinations. Strong information governance through clear retention, deletion, and ROT (redundant, outdated, trivial) data reduction policies, limits the data footprint. Cost-effective eDiscovery platforms with transparent pricing models further control spend.

5. Data Migration Complexities

The Challenge

Data migration complexities in eDiscovery stem from the challenge of transferring vast, diverse, and often sensitive datasets across different platforms, formats, or environments while preserving integrity, metadata, and legal defensibility. Legal data, which spans emails, chat logs, cloud repositories, and structured databases, must be migrated without loss, alteration, or corruption, as even minor discrepancies can compromise evidence admissibility or chain of custody. Differences in data schemas, file types, and vendor systems further complicate the process, requiring meticulous mapping, validation, and quality control. Transferring legal data between platforms risks data loss, corruption, or disruption to established workflows also contribute to such complexities. These technical hurdles, combined with confidentiality and compliance risks, make eDiscovery data migration one of the most delicate and resource-intensive phases of modern legal operations.

The Solution

There are a few solutions, such as comprehensive planning, including detailed inventories, mapping, and phased migration, which help minimize risk. Additionally, it is useful to employ rigorous quality checks, as these validate accuracy during transfers. Moreover, incorporating automation reduces manual error, while training ensures smooth adoption. And finally, specialized eDiscovery migration tools and expert support strengthen defensibility and preserve work product integrity to avoid data migration complexities.

6. Communication Gaps and Collaboration Gaps

The Challenge

Siloed teams, fragmented platforms, and ephemeral collaboration tools lead to inconsistent communication, duplicated efforts, and potential data loss.

The Solution

Solving this starts with defining clear communication protocols and centralized documentation practices support alignment. Then, it’s a must to incorporate secure document-sharing and integrated platforms, as they streamline workflows across stakeholders. These improve collaboration, as collaboration improves further when teams foster a culture of partnership with law firms and technology providers, supported by unified systems that connect diverse tools.

7. A Lack of Standardization

The Challenge

This refers to the lack of standardization across tools, formats, and processes, which creates inefficiencies, inconsistencies, and legal risks. Each platform may store, process, and export data differently, using distinct metadata fields, file naming conventions, or review protocols, making interoperability difficult. As a result, when data moves between systems or vendors, critical context can be lost, review workflows may need to be rebuilt, and validation becomes more complex. This fragmentation not only increases time and cost but also threatens defensibility, as inconsistencies in how data is handled can raise questions about accuracy and chain of custody.

The Solution

Addressing this challenge requires establishing clear frameworks and protocols that promote consistency across the eDiscovery lifecycle. Organizations can adopt industry standards such as the EDRM (Electronic Discovery Reference Model) to align processes, metadata mapping, and documentation practices. Standardizing file formats (like using native files with load files in common formats such as DAT or CSV) and implementing uniform quality control procedures can further streamline collaboration between internal teams and external vendors.

Additionally, integrating AI-driven validation and audit tools helps ensure data integrity during transfers. By embedding these standards into governance policies and training, legal teams create repeatable, defensible, and more efficient eDiscovery workflows.
