Text Messages, Court Expectations, and Better eDiscovery for Law Firms: A Case Study

Text messages are now central to litigation, yet traditional eDiscovery for law firms remains costly and cumbersome. Learn how one firm solved the mobile data challenge with PME's targeted mobile collection platform.

When a large law firm took on a high-stakes corporate litigation matter, they quickly realized that the critical evidence wouldn't be found in email or traditional documents. The case hinged on text message exchanges on personal mobile devices between key decision-makers. This reality forced the firm to confront a challenge that increasingly defines modern litigation: how to conduct defensible eDiscovery for law firms when the most important evidence lives on smartphones.

The Modern Problem: Text Messages as Evidence

The firm's predicament reflects a broader shift in legal practice. Mobile communications are no longer ancillary to litigation; they are often the core evidence. Yet most law firms continue to rely on outdated approaches to mobile evidence collection. Some attempt manual collection through screenshots. Others pursue full forensic imaging, a process that is expensive, time-consuming, and often yields enormous volumes of irrelevant data. Neither approach satisfies modern court expectations around proportional eDiscovery for law firms, and both create substantial risk of discovery disputes.

This particular firm needed a better path forward. They recognized that how mobile data was collected would matter just as much as what was collected, particularly if the opposing counsel challenged the methodology. They also needed to balance the demands of thorough evidence gathering with proportionality, client convenience, and cost control. Traditional eDiscovery tools and eDiscovery forensics approaches felt like overkill for a targeted collection effort.

The Collection Challenge

The litigation team faced several obstacles that made traditional mobile discovery approaches unsuitable:

• Custody and Control Issues: The relevant devices were client-owned phones, not company equipment. Asking executives to ship devices for forensic imaging or host onsite collection sessions created logistical nightmares and client friction. The firm needed a solution that allowed remote participation without disrupting business operations.

• Proportionality Concerns: Full device imaging would capture enormous amounts of irrelevant personal data, creating privacy risk and unnecessary review burden. The firm needed to collect only the communications relevant to the claims and defenses, not entire device backups.

• Defensibility Requirements: Discovery disputes over mobile data had become increasingly common. Courts expected clear documentation of collection methodology, chain of custody, and audit trails. Manual collection methods or inconsistently applied forensic tools would not withstand scrutiny.

• Timeline Pressure: The discovery deadline was tight, and traditional forensic approaches move slowly. The firm needed a solution that could deliver collected data quickly and in review-ready format.

Finding the Right eDiscovery Software

After evaluating options, the firm selected PME's targeted mobile collection platform. Unlike traditional eDiscovery tools designed for email and documents, or eDiscovery forensics approaches built for law enforcement, PME was purpose-built for modern litigation workflows. The decision proved strategic.

PME's approach aligned with the firm's needs in several critical ways.

• First, it enabled remote collection, allowing custodians to participate in the collection process from their own devices without shipping or onsite visits.

• Second, it supported targeted acquisition by custodian, date range, and communication type, meaning the firm could collect text messages relevant to the matter while leaving personal communications alone.

• Third, it generated comprehensive audit documentation that would defend the collection methodology against any future challenge.

Execution and Results

The collection process unfolded smoothly. Litigation team members initiated targeted collection requests, specifying the custodians, relevant date ranges, and data types required. Custodians received simple instructions and completed collections remotely, with PME support available if technical issues arose. The entire process moved quickly, without the delays and friction that accompany traditional forensic imaging or manual collection attempts.

The results justified the firm's choice of eDiscovery for law firms approach:

Defensible Documentation

Every collection included clear chain-of-custody documentation, audit logs, and repeatable workflows. When opposing counsel questioned the collection methodology, the firm could point to documented procedures and demonstrate that collections followed consistent, auditable protocols.

Accelerated Review Timeline

Rather than receiving raw device backups full of irrelevant data, the litigation team received parsed, normalized text message collections ready for attorney review. This dramatically reduced the time spent on downstream processing and allowed the team to move quickly to substantive review.

Reduced Disputes and Costs

The targeted approach meant the firm collected only relevant communications, minimizing over-collection disputes. The streamlined workflow reduced the overall cost of mobile discovery compared to traditional forensic approaches or manual collection methods.

Client Confidence

The client appreciated the minimal operational disruption and transparent process. There was no device seizure, no demand for executives to visit a forensic lab, no weeks of waiting for results. The entire collection and delivery process happened smoothly in days.

Key Lessons for Modern Litigation

This case illustrates why eDiscovery for law firms has evolved beyond traditional approaches. Several lessons emerged:

Mobile communications are now essential evidence in most litigation matters. Courts expect law firms to identify, preserve, and produce text messages and messaging app data with the same rigor historically applied to email. Firms that treat mobile evidence as optional or secondary face increasing discovery disputes and client dissatisfaction.

The way mobile data is collected matters profoundly. A court might accept mobile communications collected through a defensible, documented methodology while excluding evidence gathered through ad hoc or poorly documented processes. Investing in proper eDiscovery software and defensible collection procedures protects the evidentiary value of mobile evidence.

Proportionality is no longer optional in mobile discovery. Judges increasingly scrutinize whether parties collected more mobile data than reasonably necessary for the claims and defenses. Targeted collection approaches reduce proportionality challenges and demonstrate good faith in discovery practices.

Modern eDiscovery for law firms must address the entire lifecycle of mobile evidence, from collection through production. This requires tools and processes that preserve evidence defensibly while preparing it for efficient review. The days of shipping devices to forensic labs or relying on manual screenshots are ending.

Building Client Confidence Through Modern eDiscovery

As text messages and mobile communications play an increasingly central role in litigation, law firms must evolve their eDiscovery practices. This firm's experience demonstrates that purpose-built eDiscovery software designed specifically for legal workflows offers a superior alternative to both traditional forensic approaches and manual collection methods.

By selecting a platform that enabled targeted, remote, defensible collection, the firm reduced costs, accelerated timelines, improved client relationships, and eliminated discovery disputes related to mobile evidence. ​Contact PME to discuss how targeted mobile collection can support your legal workflows and evidence preservation requirements.
