Due diligence, or the audit and review process that accompanies any M&A transaction, covers four main areas: financial, legal, operational, and tax. Of these, legal due diligence, or LDD, stands head and shoulders above the others in terms of complexity and importance.

The scope of legal due diligence encompasses everything from IP to litigation. In this post, we’ll review the many steps of LDD and dive into its (often) complicated process.

What is legal due diligence, and why is it important?

Legal due diligence is one step of the mergers and acquisitions process. During LDD, the potential buyer seeks to gain a full legal picture of the target company. As with any component of the DD process, the ultimate aim here is to “check under the hood” and ensure everything is in order. Typically, LDD includes thorough analyses of licenses, regulatory issues, contracts, and any pending legal liabilities.

Buyers (or buyers’ legal teams) should approach the legal due diligence process by asking, “Is there any legal reason that we shouldn’t acquire this firm?” Few target companies are likely to have a completely clean slate regarding their legal history. Common examples include HR issues with departing employees or contractual disputes with suppliers or clients. Your legal due diligence process should set out to find the “red line” issues, aka the deal-breakers.

How much does legal due diligence cost?

Legal due diligence isn’t cheap, but it’s a lot cheaper than finding legal skeletons in the closet six months after the deal has closed. Don’t cut corners or you may end up paying far more than you expected down the line. Instead, create a clear agenda with the law firm and legal experts you hire, establishing where and when the costs will arrive so everyone knows what to expect.

How to perform legal due diligence

During LDD, the legal teams on both the buy side and the sell side will conduct due diligence investigations into the target company’s legal background, operations, and documentation. The goal is to uncover potential risks, review regulatory compliance, and understand current liabilities.

The LDD process will likely begin with a general review of the target company’s legal standing, and then move into an in-depth examination of the following areas:

Legal due diligence on the sell-side

It’s good practice for owners on the sell side to conduct at least part of the legal due diligence process. For one, having an external attorney sign off on some of the internal legal workings of your company is a courteous way to treat buyers. For another, it speeds up the process and better prepares your business for a frictionless and timely sale. Furthermore, if both companies have in-house legal teams, LDD offers a useful icebreaker opportunity.

Legal due diligence on the buy side

The main goal of LDD on the buy side is to ensure the target company doesn’t have any hidden legal problems that could make the sale fall through. However, LDD also helps ensure a fair valuation and purchase price and can inform the details of the purchase agreement.

How long does legal due diligence take?

Legal due diligence can take as little time as a month to as much as half a year, with the majority of LDD processes taking some amount of time between. Although LDD can be time-consuming, it’s well worth it to be as thorough as possible.

How to ensure a smooth LDD process

The most efficient way to conduct legal due diligence is via a virtual data room, which will be shared between the buy side, the sell side, and the legal teams on both. The buy side, in tandem with their attorney, should agree to a checklist of legal documents that will be requested from the sell side.

It’s important to establish some order at the outset. Begin processes that inevitably take longer first. Your attorney will know from experience which documents take the longest, but a good rule of thumb is: The further back you go with a document that can’t be retrieved in-house, the lengthier the process will be.

The importance of obtaining a legal opinion on the target firm

Even if your LDD process doesn’t raise any red flags, M&A always comes with some element of legal risk.

This is where legal due diligence differs from other parts of the process. Many of the risks you’re trying to uncover here won’t be hiding in plain sight. Suppose you’re acquiring a small pharmaceutical firm that sells drugs with some potential side effects that haven’t caused any issues until now. What are these side effects and what kind of liability would they create for your company should one (or several) of your customers be hit with them?

Answering questions like these is where your legal team pays for itself. They’ll provide you with expert opinions on whether you complete the acquisition process. The answer will rarely be a straight “yes” or “no,” but at least you’ll be making a far more informed decision based on their legal advice.

A legal due diligence checklist for M&A

The LDD process has a lot of moving parts. Having a checklist in place helps keep everyone organized and on-task from beginning to end. Below, we’ve laid out a basic checklist by LDD category that you can fit to your own needs.
