AI and Due Diligence: Reduce Risk, Accelerate the Process

Due diligence is one of the most time-consuming activities in business law. Hundreds, sometimes thousands of documents to review, under tight time pressure. It’s a space where AI offers transformative gains—not by replacing legal analysis, but by making exhaustive review humanly possible.

The Traditional Challenge

A due diligence review for a small business acquisition typically involves examining 500 to 2,000 documents: commercial contracts, employment agreements, lease agreements, permits, insurance policies, tax records, and correspondence. A lawyer can carefully review maybe 20-30 documents a day. That’s 20-100 days of work. At billing rates, that’s $40,000 to $100,000 just for document review—before any actual analysis.

And speed comes at a cost: the faster you work, the more details you miss.

What AI Changes

An AI system can read all 2,000 documents in minutes, flag unusual clauses, identify potential risks, and categorize everything by legal topic. It won’t replace the lawyer’s judgment, but it changes what the lawyer spends their time on. Instead of reading every page, you read AI summaries and spot-check the flagged documents.

Result: You can do comprehensive due diligence in a fraction of the time and cost. And you catch more risks because you’re reviewing intelligently, not just quickly.

Real-World Application

Firms that use AI for due diligence are now completing reviews in 2-3 weeks that used to take 6-8 weeks. They’re charging more reasonable fees. And they’re spotting issues in documents that human readers were too tired to notice.

In competitive deal environments, speed is leverage. AI is how you get it.
