Due Diligence Investigation
In business acquisitions, investments and significant commercial collaborations, the first questions clients usually focus on are the price, the payment structure and timing.
In practice, however, the quality of a transaction is rarely determined by price alone.
It is usually determined by how well the risks are understood. “Due diligence” is, in essence, a systematic review of the target business, project or asset before completion, designed to confirm that its legal, financial and operational position is consistent with what is presented on the surface.
In practice, transaction risks are not usually written into the contract. They tend to sit within the history and structure of the target.
Examples include undisclosed liabilities, contracts at risk of termination, employment issues, unclear intellectual property ownership and historical compliance problems that have been overlooked.
These factors may not be obvious before completion, but once a deal is done, the associated risks generally transfer with the business and are ultimately borne by the buyer. Seen in that light, due diligence is not a procedural formality. It is a core input into the transaction decision.
It answers a key question: what are you actually buying, and what potential risks does it carry?
In due diligence work, NS Legal focuses on identifying risk from a legal perspective and converting it into clear, actionable input for decision-making, so that clients have a full understanding of the transaction before signing rather than discovering issues after completion.
What is Due Diligence
Due diligence can be understood as a comprehensive review of the target business or asset before completion, to confirm whether its legal position, ownership, contractual arrangements and potential liabilities are clear, accurate and manageable.
In practice, due diligence is more than “collecting information”. The more important step is the analysis and assessment of that information.
The same contract can mean very different things in different scenarios, and the same liability can have very different effects depending on the structure of the transaction. Structurally, due diligence usually covers:
- Confirming the legal structure and ownership of the target;
- Reviewing contracts, debt and commercial arrangements;
- Identifying potential liabilities and dispute risks;
- Assessing compliance and historical issues.
The focus of due diligence is not simply to list problems. It is to answer: do these problems affect the transaction, how serious is the impact, and can they be managed through structure or contract terms?
In that sense, due diligence is a risk-assessment exercise, not just an information-gathering one.
Why Due Diligence Matters
Clients sometimes describe due diligence as a check on whether there are any problems with the deal. In practice, its value goes well beyond that.
More accurately, due diligence helps clients understand the impact of problems, not just identify them. In practice, due diligence typically has a direct effect on:
- Confirming whether the seller actually has the right to sell the business or asset;
- Identifying liabilities or obligations the buyer may take on after completion;
- Assessing whether the business is operationally stable and free from material disruption risk;
- Identifying compliance or regulatory risk;
- Providing the basis for price negotiation and adjustments to the contract.
For example, if due diligence reveals that a key contract may terminate automatically on a change of control, this is not just a “legal issue”.
It has a direct bearing on whether the business will continue to operate after completion. Similarly, where undisclosed liabilities are identified, this will often directly affect the price or the allocation of risk.
The central function of due diligence, therefore, is not simply to surface problems. It is to ensure that those problems are taken into account in the transaction decision, so that risks are not assumed passively after completion.
Key Legal Areas We Review
The focus of due diligence varies with the type of transaction. In most commercial deals, however, the following areas form the core of the legal review.
Corporate Structure & Ownership
Corporate structure and ownership are the foundation of due diligence.
They go to one of the most basic questions: does the seller have the right to sell this business or asset, and is the subject matter of the transaction clearly defined?
In practice, the following points typically need to be confirmed:
- Whether the company’s registration and legal position are in order;
- Whether the shareholding structure is clear, and whether there are any undisclosed shareholders or arrangements;
- Whether the directors and management are properly constituted;
- Whether the relevant resolutions and records are complete.
Where the corporate structure itself has issues, such as unclear shareholding, incomplete resolutions or disputed ownership, even a well-drafted contract may not be enough to ensure the validity of the transaction.
This is usually the starting point of the diligence exercise.
Contracts & Commercial Arrangements
Contracts are the foundation on which a business operates and a key indicator of its stability. As part of due diligence, we typically review the target’s main commercial contracts to assess continuity and potential risk.
The focus usually includes:
- Whether key contracts (customer contracts, supply agreements, leases) are stable;
- Whether there are change of control clauses that may be triggered after completion;
- Whether there are restrictive provisions (such as exclusivity or restraint clauses);
- Whether there are any performance-related risks of breach.
For example, if a key customer contract can be terminated by the customer following a change of control, the business may be immediately affected after completion.
Issues of that kind are not merely legal details; they have a direct bearing on the value of the deal.

Liabilities & Exposure
Liabilities and contingent exposure are among the most easily underestimated transaction risks.
Most businesses will disclose their existing debts, but the real risk often lies in liabilities that have not been adequately identified. In due diligence, attention is typically given to:
- Disclosed debts and their terms;
- Contingent liabilities;
- Guarantees, security and third-party arrangements;
- Unresolved disputes or potential litigation risks.
For example, a claim that has not yet been formally commenced, or an implied guarantee, may crystallise into actual loss after completion.
This part of the review therefore cannot rely on documents alone, and needs to be assessed against the wider business context.
Employment Matters
Employment arrangements often have a practical impact on the transaction, especially where the business is being acquired as a going concern.
Many risks are not reflected in contracts but emerge gradually through the employment relationship itself. Common points of focus include:
- Whether employees will transfer with the transaction;
- Whether there are outstanding wage or benefit obligations;
- Whether there is any potential industrial dispute or unfair dismissal risk;
- Whether employment contracts are properly drafted and clear.
Where a business has outstanding employee entitlements or potential industrial disputes, those issues may be assumed by the buyer after completion.
This area therefore needs to be assessed by reference to both legal documents and operational reality.
Intellectual Property
Intellectual property is often a central element of business value, particularly in brand, technology or content-driven businesses. In due diligence, the focus is typically on:
- Whether trade marks, copyright, designs and similar rights are held by the company itself;
- Whether there are unassigned or unclear ownership positions;
- Whether there is any infringement risk or third-party dispute;
- Whether the core commercial assets are genuinely protected.
For example, where a business is operating under a brand that has not been registered as a trade mark, or where key software code does not belong to the company, these matters can have a direct impact on the value of the transaction.
The intellectual property review is therefore not simply a formality, it is an assessment of underlying value.
Compliance & Regulatory
A business’s compliance history often shapes its future risk profile. Many issues that are not given attention in day-to-day operations are surfaced systematically through due diligence. The focus typically includes:
- Whether the business has complied with relevant laws and regulations (such as consumer law and data protection);
- Whether there is a record of regulatory investigations or penalties;
- Whether there are potential non-compliance risks;
- Whether there are clear gaps in the internal compliance framework.
For example, a business with a long history of consumer complaints or data management issues may carry that risk forward after completion.
Compliance issues therefore need to be assessed against future operations, not only as historical facts.
How Due Diligence Affects the Deal
Due diligence is not a separate step that sits outside the transaction; it is embedded in the transaction decision. Its findings typically have a direct impact on the deal structure and negotiation strategy.
In practice, common effects include:
- Where significant risk is identified, the client may re-evaluate or terminate the transaction;
- Where risk is manageable, the contract terms can be adjusted to address it;
- Risk may be reflected through price adjustments;
- Risk may be allocated through warranties, indemnities or specific provisions.
It is important to note that some issues will not stop a deal; instead, they need to be allocated reasonably through contract terms. A potential liability may, for example, be shifted to the seller through an indemnity.
The focus of due diligence is therefore not simply on “whether there are any issues”, but on whether those issues are adequately reflected in the deal terms.
Common Risks in Practice
In actual transactions, we frequently see issues of the following kinds:
- The target has undisclosed debt or potential liabilities;
- Key contracts may terminate after the transaction;
- Intellectual property does not belong to the company itself;
- Employment arrangements or historical obligations have not been properly dealt with;
- The business has compliance issues that have not been disclosed.
The common feature of these issues is that they are not obvious before completion, but continue to affect the business after the deal is done.
The value of due diligence lies in bringing these “hidden risks” to the surface in advance.
When Should You Conduct Due Diligence?
Due diligence should generally begin early in the transaction, rather than being added on after a contract has been signed. Common situations in which it is appropriate include:
- Planning to acquire a business or company;
- Considering an investment or bringing in a partner;
- A significant asset transfer or structural reorganisation;
- A transaction of significant value or risk.
The earlier diligence is undertaken, the more leverage the client typically has in negotiation, and the easier it is to adjust risk through structure rather than respond to it after completion.

Frequently Asked Questions
Is due diligence really necessary before buying a business or company?
Not every transaction requires the same depth of due diligence, but in most business acquisitions, investments and significant commercial deals, due diligence is usually very important. Many risks are not actively disclosed before completion, for example:
Undisclosed liabilities or potential exposure
Key customer contracts at risk of termination
Unclear corporate structure or shareholding
Employee entitlement issues
Unclear ownership of trade marks, intellectual property or commercial assets
Historical compliance issues
The higher the value or the more complex the structure, the less appropriate it is to rely solely on information provided by the seller. NS Legal’s commercial team can help clients scope the diligence appropriately, taking the size of the deal and the target business into account.
What does legal due diligence actually cover?
Legal due diligence is more than “looking at the contracts”. In practice, the scope may include:
Corporate structure and shareholding
Key commercial contracts
Lease arrangements
Liabilities and potential legal exposure
Employee and employment obligations
Trade marks, copyright and other intellectual property
Compliance and regulatory risk
Unresolved disputes or potential litigation risk
The precise scope depends on the transaction. For example, in the acquisition of a technology business, intellectual property may be a particular focus. In the acquisition of a physical operating business, leases, employees and supply contracts may be more important. NS Legal generally adjusts the diligence focus based on the deal structure, rather than applying a single mechanical checklist.
If I find hidden liabilities or other problems after buying a company, what can I do?
This depends on the deal structure, the contract terms and the nature of the specific issue. It will be necessary to consider, among other things:
Whether the seller gave warranties
Whether there are indemnity arrangements
Whether material information was withheld
Whether there is misleading conduct or other liability
Whether the risk was, in fact, intended to sit with the buyer
Some issues can be pursued after completion. Where the risk was not identified before completion, however, the available remedies will often be more limited. This is why due diligence itself is so important. NS Legal can help assess the legal position after completion and identify whether there is further scope for recovery.
If due diligence uncovers problems, does that mean the deal has to be called off?
Not necessarily. The identification of risk during due diligence does not automatically mean that the transaction must be terminated. In most cases, the more practical questions are:
How serious the risk actually is;
Whether it can be reflected through a price adjustment;
Whether it can be allocated through warranties or indemnities;
Whether the deal structure needs to be adjusted;
Which risks are acceptable and which should not be taken on.
Some deals are ultimately terminated because the risk is too high; many others continue, with renegotiated terms. In due diligence work, NS Legal helps clients not only identify legal risks but also assess what those risks mean commercially in light of the transaction objectives.
