M&A Legal audit - what does it involve?

A legal audit is a comprehensive process of assessing the legal status of a business conducted by a company, enterprise, or other entity. Its purpose is to identify areas that may generate risk – particularly legal risk – in the context of a planned transaction or the further development of the business.

In practice, a legal audit is often part of a broader Due Diligence process, especially when a merger, acquisition, entry of a new investor, or a transaction involving the sale of shares or assets is planned.

However, it can also be carried out as an internal project, independent of transactional plans – for example, to improve compliance levels and align operations with applicable regulations.

A well-executed legal audit allows for an accurate assessment of the company’s legal standing and prepares it for the safe execution of a transaction process.

To effectively conduct a legal audit, a detailed analysis of documentation and internal processes is required. This is typically carried out by a specialized law firm, with an experienced auditor responsible for execution, taking into account the industry specifics and the nature of the transaction.

The scope of the audit usually includes:

• ownership structure and shareholding
• legal status of key contracts
• assessment of real estate and rights to use it
• verification of intellectual property rights and other IP assets
• analysis of employment law matters
• assessment of compliance with applicable laws and regulations
• verification of key assets

A key element is identifying potential risks that may impact profitability, business value, or the feasibility of the planned transaction.

The outcome of this process is a report containing a detailed description of findings and recommendations for further actions, such as regulating ownership issues, organizing documentation, or implementing additional procedures in line with applicable regulations.

For investors, a legal audit is a tool that supports informed business decision-making. Without full visibility into the legal status of a company, it is difficult to accurately assess asset value or potential profitability.

In practice, a legal audit is one of the key stages of the Due Diligence process in M&A transactions. It forms the basis for determining contractual safeguards, liability mechanisms, and price adjustments.

Importantly, a well-prepared report not only identifies legal risks but also proposes specific corrective actions. As a result, a legal audit enables not only risk identification but also early risk mitigation, even before the transaction is finalized.

Today, the Due Diligence process is highly transactional and involves processing large volumes of documents. In larger projects, it may include hundreds of contracts, corporate documents, as well as real estate and intellectual property documentation.

That is why legal audits increasingly rely on Virtual Data Room solutions, which help organize documentation, support detailed analysis, and enable secure data sharing among multiple advisors simultaneously.

As a result, both the law firm and the auditor can conduct their analysis more efficiently, while the investor gains faster access to a complete picture of the legal status of the evaluated entity.

What is the difference between a legal audit and Due Diligence?
A legal audit focuses on a detailed assessment of the legal status of a given entity. It includes analysis of contracts, ownership structure, real estate, intellectual property, and employment law. Due Diligence is broader and also includes financial, tax, and operational analysis.

Who should conduct a legal audit?
For smaller projects, an internal review may be possible. However, in the case of a planned transaction, it is recommended that a specialized law firm conducts the audit. An experienced auditor ensures an objective analysis, taking into account industry specifics, as well as proper risk identification and compliance assessment.

How long does a legal audit take?
The duration depends on the size and structure of the company, as well as the scope of documentation related to the transaction. In larger transactions involving multiple assets, real estate, and complex ownership structures, the process may take from several weeks to several months.

Which areas are most commonly analyzed during an audit?
A typical comprehensive legal audit covers ownership structure and corporate relations, commercial contracts and liabilities, employment law, legal status of real estate, intellectual property rights, and compliance with regulations.

How does a legal audit impact transaction security?
A reliable legal audit increases transaction security by enabling early identification of risks and their mitigation before signing the agreement. This allows the investor to properly safeguard their interests, adjust the deal structure, or renegotiate pricing if identified risks affect the project’s profitability.
