What is due diligence?

You may have heard the term due diligence in real estate, law, or business. But what does it actually mean, and what does the process involve in practice?

In simple terms, due diligence is the process of thoroughly investigating a person, company, or asset before entering a transaction. It’s about gathering all the information you need to make an informed decision and mitigate potential risks.

Due diligence varies by sector—the process in real estate differs from law, and corporate transactions like mergers or software purchases have their own steps. There are also specialized forms, such as contingent due diligence and enhanced due diligence, which we’ll explore below.

‍

What is performed due diligence?

Performed due diligence refers to the effort a person or organization undertakes to fully understand another entity before doing business. It’s about care, effort, and structured investigation to avoid unforeseen risks.

‍

Types of performed due diligence

The type of due diligence depends on the context and the purpose of the transaction:

‍

Due diligence in real estate

Real estate due diligence ensures that buyers know everything important about a property before purchase. Even if the term isn’t explicitly used, most property transactions involve this process.

Key elements typically include:

• Evaluating the location for potential risks
• Checking the condition of the property
• Investigating environmental factors

Example: A professional property survey identifies structural issues or zoning restrictions. The findings help the buyer decide whether to proceed or negotiate terms.

‍

Due diligence in law

In legal contexts, due diligence involves investigating companies or individuals to understand all risks in a proposed transaction.

Legal due diligence, a subset of this process, focuses on reviewing:

• Contracts and agreements
• Compliance with regulations (e.g., GDPR)
• Corporate records and governance procedures

‍

Example: During a merger, a bank or legal team examines a target company’s contracts, board meeting minutes, and compliance measures to ensure transparency and reduce risk.

‍

Due diligence in business

In business, due diligence is considered best practice for all transactions, not just mergers. It ensures that purchases, partnerships, or investments meet company needs and standards.

Example: Buying new commercial software may involve:

• Researching pricing and customer reviews
• Checking compatibility with existing systems
• Identifying additional costs like subscriptions or add-ons

‍

Contingent due diligence

Contingent due diligence occurs when a transaction is conditional on the outcome of the investigation, such as when:

• The buyer expresses interest but will only proceed if due diligence reveals no issues
• The deal is “contingent” on these results

‍

Enhanced due diligence

Enhanced due diligence takes the investigation even further.

• Used for higher-risk transactions, individuals, or organisations
• Provides deeper insight into potential risks
• Helps determine whether risks can be mitigated satisfactorily

‍

Key takeaways: Why conduct due diligence?

While due diligence can feel laborious, skipping it exposes you to unknown risks that could have been avoided.

In short, due diligence provides the information you need to make fully informed decisions. It minimizes potential losses, reduces surprises in transactions, and applies to a wide range of industries, including real estate, law, business purchases, and more.

Think of it as preparing yourself before signing the dotted line—it ensures decisions are based on facts, not assumptions.
