M&A Virtual Data Room Due Diligence: Reviewing Contract Exports With AI

In M&A data room due diligence, counsel needs to identify contract issues requiring a deal-team decision, such as a potential consent requirement or an unresolved amendment. AI can help review the contract exports and organize source-backed findings. Counsel still needs to reconcile the document set, assess the operative terms, and identify the action each material issue requires.

Within that larger review, one narrow but consequential question is: what does the contract allow if the transaction closes? The answer can change if an amendment is missing, a later agreement supersedes the base language, or the review set does not match the data-room index.

GC AI is a legal intelligence platform for in-house counsel. As of October 2026, 2,100+ in-house legal teams across 45+ countries use GC AI. Our customers include TIME, Lockheed Martin, and Wayfair.

Use our Contract Intelligence platform when your legal team needs to review current terms across an authorized contract export, inspect cited source passages, and turn unresolved consent or notice questions into a diligence issue log. Review related agreements together so counsel can check how amendments change the base terms. Keep the transaction VDR in its approved system: our Vault does not replace an external bidder room or provide sharing outside your organization.

Decide Whether You Need a Separate Contract-Review Workspace

Assess the review tools available in your transaction VDR. Compare them with an authorized GC AI review set using the same representative agreements, amendments, review questions, and requested work product. Require source passages counsel can inspect, current terms checked across each contract family, and an issue log that identifies missing evidence and the next action. Check how each workflow keeps findings current as documents change.

Include the work of maintaining a second document set in that comparison. Name a diligence coordinator to manage exports and reconcile updates, a Vault owner to configure reviewer access, and reviewing counsel to verify findings. Confirm the proposed package's document capacity, charges, and implementation support before purchasing.

Our Team plan includes Solutions Attorney support and a product walkthrough to help reviewers learn the workflow; counsel retains responsibility for the diligence conclusions. If the VDR supports the required review, an additional workspace may add maintenance without improving the result.

On CZ and Friends, GC AI’s podcast, CEO and three-time general counsel Cecilia Ziniti talks with legal and business leaders about scaling companies, leading teams, and putting AI to work. Guest Nicole Altman, then Senior Counsel at Instacart, described the amendment-chain problem behind this workflow: a counterparty search could return dozens of agreements and amendments without one clear statement of the operative terms.

At a Bolt hackathon, she built Contract Compass, an upload-based tool to piece those changes together. The project was separate from GC AI and was not integrated with her contract database. Altman’s Contract Compass story shows why diligence findings should not rely on a base agreement until the amendment chain is reconciled.

Confirm Permissions and Scope for Data Room Due Diligence

Before moving a contract family into a review workspace, confirm the transaction team’s authorization, confidentiality restrictions, and any limits on third-party processing. Export only the documents the legal team is authorized to analyze.

Create an intake log before starting. Record the source room, export date, document name, folder path, version, and any reason a file was excluded. This gives counsel a stable reference point when a later upload changes the review set.

If the authorized review set comes through one of our supported connected sources rather than a direct upload from the data-room export, confirm the selected scope and sync settings. Pause syncing when the review requires a fixed cutoff, and record when updates resume.

• Scope: Identify the contract questions, transaction structure, critical business relationships, and deal deadlines that should guide the review. Have deal counsel set the escalation criteria.
• Cutoff: Record the export date and time.
• Versions: Mark amendments, superseded agreements, and duplicate files.
• Exclusions: List unreadable, unsupported, missing, or out-of-scope records.
• Authority: Record who approved the export and the AI workflow.

Record company priorities, escalation criteria, and approval requirements in manual columns or reviewer notes. Have deal counsel supply and maintain that guidance so reviewers can identify findings that need a consent request, notice, or escalation. Keep these company instructions distinct from terms extracted from the contracts; counsel decides whether an exception needs approval.

Check Data-Room Export File Types Before Importing

In Contract Intelligence, you can bring authorized contract files into a Vault through direct upload or supported connected sources. Vaults accept contract-oriented PDF, Word, and plain-text documents. Scanned PDFs are supported through OCR; check the extracted text against the scan. Connected sources can also bring in Google Docs and Google Slides. PowerPoint files, standalone images, spreadsheets, and .msg or .eml emails are not supported as Vault documents. Spreadsheet trackers can be imported separately to add their columns.

Use the intake log to track which exported files can enter the Vault. A data room may contain contracts beside financial models, presentations, correspondence, and scanned documents. Route unsupported files through a separate approved workflow, or leave them on the exclusion list until the review team confirms a supported method against current product documentation.

Review M&A Contracts With AI and Verify Findings

Once the authorized contract set is in Contract Intelligence, think of the workspace as a lawyer-controlled review table. A Vault holds the authorized documents; Columns let the team ask the same diligence question across the set; Related Documents groups a base agreement with its amendments; and Current Terms helps counsel review how those amendments affect the operative language. Each extracted result should lead back to source text a lawyer can inspect.

Watch how our Contract Intelligence works:

For an assignment-clause review, use separate Columns for the assignment restriction, change-of-control language, consent requirement, notice requirement, and stated exceptions. Ask each Column to cite its supporting passage and identify when the supplied documents do not establish the term. Counsel then considers the fields together against the transaction structure and applicable law.

For each contract family, confirm or correct the suggested Related Documents relationships, then use Current Terms to review how amendments affect each term. Check the cited language in the underlying files. Relationship mapping finishes after document analysis, so an unlinked amendment can mean processing is still underway. Reconcile the complete family before reporting the term as current.

A View is the review table for the documents and Columns you select. Use manual columns or notes to record counsel’s conclusion and why a finding remains open, separately from the extracted terms. Counsel decides whether the transaction triggers a provision.

Illustrative review view: Suppose an agreement contains an assignment restriction, and the data-room index lists an amendment that is missing from the authorized review set. Keep the contract family, source finding, extraction, evidence gap, counsel decision, and follow-up separate.

Review field	Example finding	Reviewer action
Contract family	Services agreement plus the amendments available in the authorized review set	Compare the review set with the data-room index and identify any missing related document
Source language	In this hypothetical agreement, assignment requires prior written consent, with an exception for transfers to a wholly owned affiliate. Record the section and source citation.	Open the cited clause in the original file and read it in context
Extraction result	The reviewed agreement requires prior written consent for assignment and states a wholly owned affiliate exception	Check whether the exception is relevant to the proposed transaction and whether any amendment changes it
Evidence gap	The data-room index lists an amendment that is missing from the authorized review set	Keep the issue open and ask the deal team to locate the amendment
Counsel decision	Open pending review of the missing amendment and transaction structure	Record the conclusion only after the missing source and deal structure are reviewed

Assign an owner and deadline to the missing-amendment request. Keep the item open until counsel records the source reviewed and the resulting decision.

Example deal-team update: “Consent review remains open for this services agreement. The base agreement contains an assignment restriction and an affiliate-transfer exception, but the indexed amendment is missing. Seller counsel should provide the amendment so our legal team can assess the complete terms against the proposed transaction.”

For every material finding, check the cited clause in context and confirm that the complete contract family supports the conclusion. If the transaction raises a disputed legal question, research it separately before recommending a consent request, notice, or escalation.

Reconcile Data Room Exports and Update Diligence Findings

After reviewing individual findings, compare the imported set with the export index. Reconcile original filenames and document contents, rather than row counts alone: Contract Intelligence can rename documents, split a compound PDF into separate rows, and consolidate exact duplicates. Check for missing folders, duplicates, superseded terms, and unreadable files. Mark uncertainty explicitly rather than treating an empty extraction field as proof that a term is absent.

When the seller adds files, record the new export date and filenames, reconcile them with the index, and connect related documents to the relevant contract family. Have counsel review additions for changed terms and new issues, compare the new source passages with earlier conclusions, and update affected findings in the issue log. Record what changed, why the conclusion changed, who verified it, and which questions remain open.

Keep the VDR as the Transaction Source of Truth

The transaction VDR remains the approved source of truth. In our Contract Intelligence workflow, record unresolved issues in the diligence log with the missing evidence, owner, and deadline. Label a finding confirmed only after counsel checks the complete contract family and the relevant transaction facts.

Export the reviewed View to CSV for the team's diligence tracker, keeping the contract identifiers, review status, owner, and open questions together. Check the exported fields before using them in the report, and retain the source references needed to verify each material finding. Use the legal due diligence report template and example to structure that report. For the broader M&A and vendor diligence landscape, see the AI due diligence guide.

For the demo, write down the expected current term and the missing-document condition in advance. During the demo, note how much lawyer review or correction is required to reach an approved result.

Bring a small synthetic contract set to a GC AI demo: a base agreement, an amendment that changes a deal-relevant term, and an index listing one deliberately omitted attachment. Ask us to show the cited extraction and amendment history in Contract Intelligence.

Compare the imported files with the index, then have counsel verify the changed term and record the missing attachment as an open issue. Choose GC AI for this contract-review workstream when the pilot produces a source-checked issue log with operative terms, unresolved evidence, and an owner for each follow-up, and your team can sustain the export and review work.
