eDiscovery

Several cost drivers define eDiscovery in 2026:

– Large data volumes (cloud storage, Slack, Teams, mobile data)

– Attorney document review (the most expensive phase)

– Forensic-grade collection requirements

– Regulatory compliance (FRCP, GDPR, CCPA)

– Data hosting and analytics platforms

The cost of non-compliance, including sanctions, adverse inference rulings, and reputational damage, often exceeds the cost of defensible eDiscovery. Strategic data scoping and early case assessment are essential to controlling overall spend.

The eDiscovery process follows a structured framework known as the Electronic Discovery Reference Model (EDRM). It ensures electronically stored information (ESI) is handled in a defensible manner.

The core stages include:

1. Identification of relevant custodians and systems

2. Preservation through legal holds

3. Forensic collection of data

4. Processing and deduplication

5. Document review for relevance and privilege

6. Production in agreed legal formats

7. Presentation in court or proceedings

Each stage must maintain chain of custody, metadata integrity, and audit trails to ensure admissibility.

eDiscovery includes all electronically stored information (ESI) that may be relevant to a legal matter.

Common data sources include:

– Emails and attachments (Microsoft 365, Gmail)

– Cloud storage (Google Drive, OneDrive, SharePoint, Box)

– Collaboration platforms (Slack, Microsoft Teams, Zoom chat)

– Text messages and mobile app data (SMS, WhatsApp, iMessage)

– Databases and structured data systems (CRM, ERP)

– Social media content

– System logs and audit trails

– Backup and archived data

Modern litigation frequently involves cloud-native and collaborative data, which requires specialised forensic collection to preserve context and metadata.

Managing eDiscovery for cloud storage requires defensible, API-based collection methods.

Best practice includes:

– Identifying relevant custodians and shared drives

– Implementing legal holds to prevent alteration or deletion

– Collecting data via forensic tools that preserve metadata and version history

– Capturing comments, sharing permissions, and revision logs

– Processing and deduplicating shared files

Cloud environments create duplication and version complexity. Proper handling ensures defensibility and reduces review costs.

Effective eDiscovery is proactive and risk-focused. 

Key best practices include:

– Establishing strong information governance policies 

– Implementing defensible legal hold procedures 

– Using forensically sound collection methods 

– Conducting Early Case Assessment (ECA)

– Leveraging AI and Technology-Assisted Review responsibly 

– Maintaining full documentation and audit trails 

– Applying proportionality under FRCP Rule 26 

– Reducing risk before reducing cost is the foundation of defensible eDiscovery.

A legal hold is required when litigation is reasonably anticipated, not only after a claim has been issued.

Triggers may include:

– Letters before action

– Regulatory enquiries

– Internal complaints indicating potential litigation risk

– Government or regulatory investigations

– Explicit threats of legal proceedings

Once litigation is foreseeable, organisations must preserve relevant electronically stored information (ESI). Failure to do so may result in sanctions, fines or adverse inference rulings.

A defensible legal hold process includes issuing written notices, tracking custodian acknowledgements, suspending automatic deletion policies and maintaining ongoing compliance monitoring.

The length of eDiscovery depends on case complexity, data volume, and the number of custodians.

The document review phase usually takes the longest. Early scoping, targeted collection, and analytics can significantly shorten timelines.
