AI Diligence Analysis

Overview

DealRoom is an end-to-end M&A platform that allows deal teams to manage diligence (including legal workstreams) from inception through completion in a single integrated workspace. While DealRoom isn’t built exclusively for legal teams, it offers them a centralized place to collaborate on contract review and manage diligence in-context, alongside the deal process, when supporting M&A deals. 

Instead of tracking deal documents in spreadsheets, email threads, and separate data rooms, DealRoom keeps everything related to the deal in one central workspace. Legal teams can review documents and manage diligence activities within structured workflows. Diligence tasks and data stay connected to contracts and data are stored centrally in DealRoom as teams move through the deal process. This allows legal work to stay connected to the rest of the transaction, rather than operating in a silo. 

DealRoom includes AI-powered contract analysis that instantly highlights key clauses and summarizes contracts. Legal teams can review contracts more efficiently, allowing them to focus their attention on applying judgment instead of manually reviewing hundreds of lengthy legal documents. 

What differentiates DealRoom from other solutions is how it connects diligence activities to the rest of the M&A lifecycle. When legal teams uncover findings during diligence, they don’t get lost after deal signing. They stay connected to the deal throughout integration planning. Teams can easily track any open items discovered during due diligence (like obligations, risks, etc.) even after the deal has closed.

Purpose-Built for the Modern M&A Lifecycle

  • DealRoom Pipeline:

    DealRoom houses your entire M&A pipeline. Documents reviewed during initial research stay connected to the deal opportunity. Information doesn’t get lost when diligence begin.
  • DealRoom Diligence:

    Use DealRoom Diligence as your team’s primary legal workspace throughout the transaction. Stash document requests in one centralized request list. Store contracts in the built-in data room. Leave comments and questions attached to specific files under review.
  • DealRoom Integration:

    Findings gathered during legal diligence connect to your post-close integration planning with DealRoom Integration. Any legal risks identified during diligence can flow directly into the integration phase. You won’t have to recreate the wheel once the deal closes.

This structure keeps legal diligence tied to the rest of the deal instead of operating as a disconnected workstream.

Key Features

  • Legal Contract Repository:  

    Automate requests for legal due diligence. Tie each request to underlying documents, reviewers, and deadlines. Statuses are kept up-to-date in real time and minimize email communication with sellers/advisors.
  • Contract Organization and Version Control:

    Upload contracts to DealRoom’s secure data room for version control and centralized storage. Files remain searchable even after you upload them. You can access previous versions of contracts and export exact file revisions for reference.
  • AI-Assisted Contract Review

    : DealRoom’s AI tools scan through contracts to identify clauses related to changes of control, termination rights, and more. Legal teams can quickly identify patterns found across similar agreements then flag any outliers for review.

    Granular Access Controls:

    Control who can view contracts and see supporting documents. Hide confidential contracts from team members and share with outside counsel only.

    Activity Tracking and Audit Logs:  

    View changes and activity within DealRoom. You’ll always know who viewed which document and when. Audit trails make it easy to maintain regulatory compliance and resolve disputes.

    Collaborative Legal Review:  

    Leave comments for counsel, colleagues, and advisors. Add comments directly to documents or requests. Keep questions organized by attaching them to requests or specific contracts.

Nexis Diligence+

Why Legal Due Diligence Software?

Legal due diligence is the hub of every deal. Contracts must be reviewed. Corporate records must be verified. Risky compliance issues need resolution before moving forward.

But for many legal teams, due diligence lives in emails, spreadsheets, and shared folders. Fragmentation of the diligence process begins before diligence even starts and continues throughout.

Error potential increases as the number of documents increases. Someone may miss a clause in a contract. Someone else may review the wrong document. By the time you realize there’s a problem, you may already be behind schedule on closing.

Legal due diligence software reduces that risk. It provides teams a single environment where diligence documents, requests, reviews, and findings all live together. Lawyers spend less time searching for data and more time analyzing risk.

What You Gain with Legal Due Diligence Software:

  • Get Centralized Legal Workflows

    • Contracts, company records, diligence requests, and anything else is housed in one workspace. Lawyers no longer toggle between spreadsheets, emails, and filing cabinets to track progress.
  • Speed Up Contract Review

    • AI assisted search and other technologies can crawl through your contracts to identify clauses relevant to the deal. Lawyers review the findings but don’t have to spend as much time searching.
  • Track Issues with Clarity

    • Findings from due diligence can be created as issues, assigned to the right team, and tracked to resolution. Deal teams have visibility into what issues remain open.
  • Collaborate Seamlessly with Deal Teams

    • Corporate development, legal, and outside counsel can review documents and collaborate on issues in-platform. Discussion stays with the file instead of getting lost in email threads.
  • Create Clear Audit Trails and Accountability

    • Document views, updates, and comments are logged and kept. When issues come up months into the deal process you’ll have a record of who saw what and when.

What’s at Stake Without It?

  • Unclear Legal Risks

    • Trying to conduct due diligence from a spreadsheet and email leaves too much room for human error. Missed clauses. Unfamiliar contract language. What looked like minor details can turn into gaping holes once the deal is signed.
  • Time Lost During Deal Phases

    • Lawyers waste valuable hours searching for document versions, tracking down files, and following up on requests that went unanswered. Frustrating? Yes. But that time isn’t being used to do actual legal work.
  • Miscommunication Across Workstreams

    • Corporate development, legal, and outside counsel typically keep their own records of diligence activities. Information gets siloed and sharing updates can take time.
  • Unclear Review Procedures

    • If each deal runs through a slightly different process, then it’s likely that review findings will vary from person to person. One issue may be called out in one deal but missed on the next.
    • Document review keeps stacking up, but diligence timelines don’t slow down for your growing deal funnel. Legal due diligence software can help your team gain the control, visibility, and process they need to handle any deal that comes their way.

Types of Legal Due Diligence Software

There are solutions for every part of the diligence process. You have tools for contracts, document review/collaboration platforms, compliance tools, and risk screening applications.

Law firms and corporate legal teams may use several solutions throughout the deal process. Below are the categories of tools you will come across when searching for legal due diligence software.
  • Virtual Data Room (VDR) Platforms

    • Virtual data rooms are usually at the center of diligence efforts. These platforms host all the confidential transaction documents including contracts, company records, and policies. Confidential documents are stored in one central repository buyers and advisors can securely review.

      Data rooms allow you to set permissions, index documents, ask questions, monitor activity. You can keep legal teams organized with large document sets and who is reviewing what.

  • Contract Analysis and Legal AI Tools

    • Contract analysis tools use artificial intelligence to extract data from your contracts. The tool scans each agreement and identifies important clauses.

      Assignment provisions, change of control rights, indemnification provisions, and termination clauses are standard clauses AI tools detect. You no longer have to read each contract yourself, just search all contracts at once to compare language.

      Examples: Kira by Litera, Parsl AI, Emma Legal
  • M&A Lifecycle and Deal Management Platforms

    • Corporate development, legal, and Deal management platforms focus on the larger deal process. From tracking deal flow, to assigning diligence tasks, sharing documents, and linking diligence findings to integration planning.

      Lawyers use deal platforms to connect requests for information, documents, and risk findings to the transaction itself. Helps deal teams stay organized as diligence progresses.

      Examples: DealRoom, Midaxo
  • Compliance and Risk Screening Tools

      • Contract review is only one part of legal diligence. You will also have to research counterparties, company officers, and business structures.

        Risk intelligence platforms pull information from sanctions lists, litigation databases, public records, and global news. Lawyers use these platforms to do screenings on people and companies. You can find risks such as regulatory risks, previous lawsuits, and other reputation risks.

        Examples: Nexis Diligence+
    • Legal and Governance Operations Platforms

        • Platforms in this category are built more for legal operations teams inside organizations. Solutions that focus on managing contracts, entities, board documents, and compliance material.

          Typically not tailored for performing M&A transactions but can aid in diligence by helping you organize company records.

          Examples: DiliTrust

      How to Choose the Best Legal Due Diligence Software

        • Ideally, legal due diligence would make contract review, document sharing, and risk tracking easier. In reality, diligence tends to get messy because your tools vary from stage to stage. You have document management software, contract analysis tools, and a separate platform to track requests/issues.

          Before you can pick the right platform you need to understand how diligence is handled at your organization.
      • Map Out Your Diligence Workflow

        • How does your team currently operate? Take notes on the following:
          • Where Where do contracts get stored?do contracts get stored?
          • How do they keep track of document requests?
          • What tool do they use to record issues/findings?
          Once you understand how diligence works at your organization, you can begin to identify opportunities for improvement. If those three elements aren’t already integrated into a single platform, your due diligence software should at minimum connect those dots. You’ll save yourself a lot of headache if you have a tool that connects your contracts, document requests, and team communication.

          Deal teams will often gravitate toward a virtual data room first. VDRs were made for storing sensitive documents, and they allow you to give multiple reviewers secure access to transaction docs.
      • Consider Security and Permissions

        • Contracts, IP portfolios, litigation history, and employee policies are all examples of sensitive data that gets shared throughout diligence. You should look for a platform that offers bank-level encryption, role-based permissions, and granular controls for sharing documents.

          You should be able to limit certain reviewers to view-only access or restrict the ability to download documents entirely.

          Audit logs are also important. You should look for a platform that tracks when someone opened a document and when they closed it. Audit logs become really useful if there’s a dispute later about who knew what during the deal.
      • Evaluate Contract Analysis Capabilities

        • Reviewing agreements is a big part of any diligence process. If you’re doing due diligence on a company that has hundreds of contracts, you’ll want software that can automate parts of the review process.

          Many legal due diligence platforms come equipped with AI that can search across documents and identify clauses, obligations, etc. Sure, you can manually search for keywords in contracts but that takes forever. Enabling full-text search can save you hours by allowing you to find specific terms across your contract repository.

          Remember, your goal shouldn’t be to automate legal review. Your goal should be to minimize the amount of time your lawyers spend searching for information.
      • Look for Collaboration and Workflow Tools

        • Due diligence is a team sport. You don’t want to silo lawyers from the rest of corporate development, finance, or external advisors.

          Ideally, the diligence platform includes tools for teams to share documents, ask questions, assign action items, and monitor the progress of requests from a central location. Good due diligence platforms make it easy to assign tasks and keep all communication about a document in one place.

          Without centralized communication, your Q&As will get lost in email threads.
      • Factor in Deal Volume & Complexity

        • Every organization is different. The ideal platform for your organization will largely depend on how many transactions you process each year.

          Law firms may only need contract review software with built-in analysis features. Mid to large sized companies performing numerous transactions per year may benefit from a full deal management solution. Smaller companies who do diligence only occasionally might be fine with a virtual data room.

          Picking a platform that aligns with your deal volume ensures you don’t pay for expensive features your team won’t use.
      • Don’t Overlook UX/UI

        • Due diligence isn’t a relaxed process. You shouldn’t have to wait weeks for IT to configure a platform before your deal teams can access it.

          Nobody has time to administer a tool or manage software training. If your software isn’t intuitive enough for outsiders to onboard themselves, you’ll need to hire someone to do it for you. Expecting your team to wait on IT will only delay your diligence process.

          Software should simplify your diligence process. If learning how to use the software adds more steps to your process, your software is doing more harm than good.

          When selected carefully, legal due diligence software can streamline contract review, organize documentation, and make it easier to track risks throughout the transaction.

      Frequently asked questions

      What is legal due diligence in mergers and acquisitions?

      Attorneys perform legal due diligence to identify any liabilities of the target company. Lawyers will review contracts, company records, intellectual property, litigation history, and regulatory obligations. The goal of legal due diligence is to uncover any material risks before the buyer consents to closing the transaction.

      What kinds of documents are looked at during legal due diligence?

      Attorneys will want to review contracts with customers, vendors, and employees. They’ll also look at IP registrations, corporate governance documents, litigation history, regulatory licenses, compliance policies, and lease documents. Reviewing these documents helps lawyers identify potential deal obligations, restrictions, or risks.

      How is AI used for legal due diligence?

      AI can extract important clauses found in contracts such as change of control, termination rights, or assignment restrictions. AI allows lawyers to quickly identify hundreds of contracts that contain these clauses. Rather than scrolling through contracts one-by-one, lawyers can focus on evaluating deal risk.

      What’s the difference between a virtual data room vs legal due diligence software?

      Virtual data rooms are used to store and share confidential documents related to a transaction. Many legal due diligence platforms have a data room feature as part of their software. Legal due diligence software often has additional features like contract analysis, diligence request management, AI clause extraction, and deal risk reporting.

      When would I use legal due diligence software?

      Legal due diligence software can be used for mergers, acquisitions, private equity deal due diligence, divestitures, and other corporate transactions. Legal due diligence can also be used for vendor due diligence, partnership assessments, or regulatory investigations.
