Streamlining Legal Doc Review: Strategies for Modern Firms

When most people imagine legal work, they envision the high-drama courtroom scenes from TV shows and movies — heated cross-examinations, surprise evidence, or pivotal moments that sway the jury.

But some of the most important work begins outside the courtroom spotlight, with legal teams combing through piles of documents to identify the most pertinent details of the case. This process of legal document review (or just “doc review” for short) is the most time-consuming part of any case. 

In large matters, it may involve millions of digital and physical documents and account for up to 80% of total litigation costs, and firms can’t afford shortcuts. Even one overlooked email or misclassified file can change the outcome of a case.

So, what does doc review entail, and why is it so costly and critical? We’ll explore those answers below— and provide some guidelines for streamlining the process.

What Is Legal Document Review?

Legal document review is the process in which teams examine and analyze documents to determine the information that’s most important, privileged, and relevant to a case. Attorneys, paralegals, and legal assistants — any trained legal staff — act as reviewers to sort through emails, contracts, memos, and other records to find evidence and prepare for trial or settlement.

The purpose of doc review is to ensure the most relevant documents are shared in discovery without exposing privileged information. Due to the daunting volume of data, it’s often the most resource-intensive part of a case.

What Does Doc Mean in Legal Terms?

In a legal context, “doc” is simply shorthand for “document.” This includes not only paper but also emails, legal contracts, spreadsheets, text messages, handwritten files, or any other relevant notes. When attorneys and their staff talk about docs, they’re referring to any record—physical or digital—that must be reviewed, categorized, or potentially brought to court.

The Doc Review Process

The volume of documents isn’t the only reason doc review is so resource-heavy. It takes a diligent process to narrow down the docs and correctly tag everything for production and trial use. It’s important to understand legal documents inside and out so nothing is missed and everything is handled properly.

Here are the typical stages of doc review.

1. Collection and Processing

The initial stage of legal document review entails collecting all potentially relevant documents from various sources, including email servers, chat logs, cloud storage, and physical file systems. Staff process these documents into files that can easily be reviewed, usually as digital PDFs with optical character recognition (OCR) for quick searchability.

An organized, efficient legal document management system goes a long way at this stage. Scattered, haphazard document storage inevitably slows down the process and leads to errors, but a well-managed system helps teams avoid missing vital documents.

2. Assessment and Culling

After processing, the team performs an initial assessment, often referred to as a first-level document review. Reviewers scan documents to remove irrelevant files or duplicates and flag materials for closer examination. They’ll cull out irrelevant docs using date ranges, keywords, sources, or metadata filters.

The goal of this phase isn’t so much to conduct a deep analysis, but rather to reduce the mountain of documents to a more manageable size. Effective first-level doc review helps legal teams move the most pertinent documents forward for detailed legal analysis.

3. Reviewing and Tagging

Once they’ve narrowed down the document set, reviewers run a more detailed analysis, reading and tagging them for factors like relevance, privilege, and confidentiality. As the core of doc review, this requires close attention to the content of each document. Using tools such as AI-assisted review and multi-file search can speed up this process without diminishing accuracy.

Because this step involves careful legal analysis and judgment, it’s often billable work for paralegals and attorneys. Teams track their time in detail so the firm can bill clients accurately for this labor-intensive phase.

4. Second-Level Review

After the initial detailed tagging, many firms conduct a second-level review for extra quality control. More experienced document review attorneys or senior reviewers re-examine documents marked as highly relevant or privileged to verify they were correctly classified.

This is also the time to check for any legal compliance issues and ensure adherence to court rules, privacy regulations, and professional standards. Reviewers look for details that may impact case strategy, minimize risks, and perform a final quality check before production or trial preparation.

5. Production and Preparation for Trial

Once the document set is finalized, the team must prepare the selected documents for production to opposing counsel and for use at trial. Teams must turn the final selections into organized sets of documents with all redactions properly applied. Documents may be shared electronically, but teams may still need to send legal documents by mail to meet court requirements or opposing counsel’s preferences. 

With production complete, attorneys and their staff can use the finalized materials to prepare trial exhibits, create witness outlines, and form the overall case strategy. A well-organized production process can make a huge difference in presenting a persuasive case in court.

6. Ongoing Review

Document review doesn’t end once initial production is complete. As a case evolves, new evidence can emerge, and additional documents might need to be revisited.

“When it comes to document reviews, don't just review them once and think you are done,” says Martin Gasparian, attorney and owner at Maison Law. “Always do follow-up reviews as the case continues, you don't have to review everything, but you need to conduct spot checks and get your team a part in it for collaboration. A second or third pair of eyes can improve not just perspective but relevance as well.” 

Why Is Doc Review So Important?

Legal document review helps legal teams thoroughly understand every piece of evidence before proceeding with a case. A thorough review can identify key facts, protect sensitive information, and develop the most effective legal strategy for the case.

“Legal document review is critical,” says Claudio Klaus, GPLL.M student at the University of Toronto Faculty of Law and host of the Studying Law Around the World podcast. “Whether it’s for litigation, regulatory response, or due diligence in transactions, the ability to catch key details and patterns often shapes outcomes. A missed clause or overlooked inconsistency can shift the legal strategy entirely.”

In short, doc review is the starting point for the entire case.

Challenges to Reviewing Legal Docs

Even the most experienced legal teams face obstacles in doc review. Between sheer volume and tight deadlines, it's easy for errors to slip through. Here are some of the challenges that make legal document review especially demanding:

‍High volume of documents: Large cases can involve millions of pages, which strains firm resources and makes it difficult to review every item.

• Time constraints: Courts, regulators, and clients all expect fast turnarounds, increasing pressure to collect and review documents quickly.
• Consistency: Having various team members use different document review methods can lead to inconsistent tagging or conflicting decisions.
• Protecting privileged and confidential information: Identifying and redacting sensitive content helps prevent accidental disclosure, which can lead to legal penalties, erode client trust, or jeopardize the entire case. It’s a necessary but time-consuming step.
• Version control: Presenting conflicting versions of a document for analysis or at trial can undermine a case. Avoiding this problem requires teams to track changes and keep up-to-date versions of each doc.
• Cost management: As the most resource-heavy part of discovery and case preparation, doc review always brings significant budget concerns. The vast number of documents and intricate review process can quickly drive up costs for firms and their clients.

How to Streamline Doc Review

Legal document review can quickly become overwhelming, but the right strategies and legal tech can make the process far more efficient and accurate. Many firms start by hiring document review specialists to apply their expertise and accelerate the review process.

Technology is also playing a more integral supporting role. Advanced search, tagging, and document management systems allow reviewers to quickly locate key information and track changes without creating conflicting versions. Even specialists can use AI-powered tools to automate initial reviews, flagging important points so human reviewers can focus on higher-level analysis. 

As Raymond Rodis, lawyer and CEO of Digest PH, explains, “AI can automate the first-pass read of lengthy legal documents because it allows them to flag or summarize insights from the bundle of documents.”

The benefits of these tools go beyond reviewing file-by-file information more efficiently. With capabilities like Rev insights, a tool like Rev helps legal teams search across all transcripts and supporting files at once, then summarize and extract insights from multiple documents in seconds. With less time wasted on repetitive tasks, attorneys and their staff can devote their energy to building a stronger case strategy.

The Future of Doc Review

With new technologies in play, doc review is evolving quickly. Online legal document review platforms like Relativity, Everlaw, and DISCO are now the norm, so legal teams can collaborate from anywhere without missing a beat. These cloud-based platforms offer secure access, real-time updates, and integrated tools that improve the entire review process.

AI, machine learning, and natural language processing continue to reshape the process of document analysis. Tools like Rev and Logikull can help with automated sorting and pattern identification, leaving human reviewers to focus on legal judgment and strategy.

As these technologies develop, legal professionals must learn to work with AI-generated insights and make strategic, data-driven decisions.
