Due diligence: the legal audit before buying, selling or partnering

Gabriel Cordeiro Grisostolo · OAB/PR nº 136.464

Few business regrets are as costly as signing before checking. Buying a company and discovering, months later, an employment debt no one mentioned; acquiring a property that carries an old attachment; entering a company whose tax liability only surfaces when it is already too late. Due diligence exists precisely to avoid that kind of surprise. It is the legal audit carried out before deciding, so that the risk is known while there is still time to negotiate, price it in or walk away. This text explains what it is, its types, how the process works and what is examined on each front.

Key points

  • Due diligence is the prior legal investigation of a company, a contract or an asset, carried out before buying, selling, partnering or investing, with the aim of revealing hidden risks and liabilities.
  • There are different types according to the object: corporate, contractual, real-estate, tax, employment, environmental and integrity. Each transaction defines which fronts matter.
  • The result is a picture of the risk: a report that informs the decision, supports the negotiation of price and guarantees, and keeps the problem from surfacing after signing.

What is at stake when you sign without checking

The pattern of the loss is almost always the same. The problem was not in plain sight, the deal looked good, haste and trust did the rest, and the bill arrived later, once the contract was signed and the money had changed hands. An employment or tax liability that follows the acquired company. A supply contract with a clause that compromises the operation. A property with an issue on its title or a burden that prevents the intended use. A company whose partner brings along a dispute that spills over into the business.

In all these cases, the harm does not come from the risk itself, which exists in any transaction, but from the fact that it stayed hidden until after the decision. Due diligence reverses that order: it brings the risk before signing, when it can still be negotiated.

What due diligence is and what it is for

Due diligence, an expression that translates as owed care, is the organized and systematic investigation of a company, a contract or an asset, conducted before a relevant transaction, to learn its real legal situation. Its aim is not merely to find defects; it is to produce reliable information to decide: whether the transaction should go ahead, at what price, with what guarantees and under what conditions. A liability revealed in time can become a discount on the price, a demand for a guarantee or a clause of seller's liability. The same liability, discovered later, becomes a loss. It is that difference that due diligence delivers.

The types of due diligence

There is no single due diligence, but fronts of investigation that combine according to the object of the deal.

Corporate due diligence

It checks the company's structure: the partners, the corporate acts, the shareholdings, the powers of management, any disputes among partners and the regularity of the resolutions. It is the basis of any acquisition or entry into a company.

Contractual due diligence

It examines the company's or the transaction's relevant contracts: term, termination clauses, guarantees, obligations assumed and risks of default. It answers the question of what the company owes and what it is bound to.

Real-estate due diligence

Before buying a property or contributing it to a transaction, it checks the up-to-date title, the chain of ownership, the existence of burdens, attachments and encumbrances, the regularity before the municipality and the certificates of the owners. It is where you discover, in time, whether the property can really be used for what is intended.

Tax and employment due diligence

It maps debts, installment plans, assessments and tax and employment contingencies, generally in coordination with the accounting and with the professionals of those areas, because they are liabilities that tend to follow the acquired company.

Integrity and environmental due diligence

Integrity due diligence, linked to compliance, investigates the history of sanctions, involvement in wrongdoing and the counterparty's reputational risks. Environmental due diligence checks licenses, liabilities and compliance when the activity or the property so require.

How the process works

Those who ask how to carry out due diligence want to understand the process, which usually follows five moments. It begins with the definition of scope: what will be investigated, in what depth and on which fronts, in light of the type of transaction. This is followed by the collection of documents, today almost always organized in a digital repository, the so-called data room, where the party under review makes the documents available in a controlled way. Then comes the analysis by area, in which each front is examined by whoever has the competence for it. The findings are consolidated into a risk matrix, which ranks the problems by severity and probability. And it all culminates in the report, which turns the investigation into a clear reading of the risk and into practical recommendations for the negotiation.

How much does due diligence cost

The cost of due diligence is not a fixed figure, because it depends directly on the scope. Investigating a single front, such as the real-estate review of one property, is quite different from auditing an entire company across several areas, with hundreds of contracts and an extensive data room. The components of the cost are usually the fees of the professionals involved, legal and, as the case may be, accounting and audit, and the time of analysis, which grows with the volume of documents and the complexity. That is why a generic price makes no sense: the amount is defined after the scope is set. Given what a post-signing surprise usually costs, however, due diligence tends to be the smallest of the transaction's investments.

Who does it and when to do it

The legal front of due diligence is conducted by a lawyer, in coordination, when the case calls for it, with accountants and auditors for the accounting, tax and employment areas. As to timing, the rule is simple: due diligence is done before signing. Before buying or selling a company, before admitting a new partner, before acquiring a relevant property, before raising an investment that requires transparency about your situation. Done afterwards, it stops being prevention and becomes merely the inventory of a problem that is already yours.

Frequently asked questions

What does due diligence mean?
It is the prior legal investigation of a company, a contract or an asset, carried out before a relevant transaction to learn its real situation and reveal risks and liabilities. The expression translates as owed care. Conducting that investigation with method is a preventive advisory service provided at Grisostolo Advocacia.
What is the main aim of due diligence?
To produce reliable information to decide: whether the transaction should go ahead, at what price, with what guarantees and under what conditions. A risk revealed in time becomes a discount, a guarantee or a protective clause; discovered later, it becomes a loss. Turning the findings into clauses that protect the party is part of the firm's work.
What are the most common types of due diligence?
Corporate, contractual, real-estate, tax, employment, environmental and integrity. Each transaction defines which fronts matter. Setting the right scope, investigating neither too little nor too much, is a technical decision the firm's preventive advisory helps to make.
What is contractual due diligence?
It is the front that examines the relevant contracts of a company or transaction: term, termination clauses, guarantees, obligations and risks of default. It answers what the company owes and what it is bound to. The analysis of the contracts, and the drafting of the resulting guarantee clauses, is a legal service developed at the firm.
How does the due diligence process work?
In five moments: definition of scope, collection of documents (generally in a data room), analysis by area, consolidation into a risk matrix and a final report with recommendations. Conducting this process end to end, from scope to report, is what the firm offers on the legal front.
Who does due diligence?
The legal front is conducted by a lawyer, in coordination with accountants and auditors for the accounting, tax and employment areas. At Grisostolo Advocacia, the legal coordination integrates with these professionals so that the investigation covers every relevant front.
How much does due diligence cost?
The cost depends on the scope: a single front, such as real-estate, differs greatly from the audit of an entire company. The components are the professionals' fees and the time of analysis, which grows with the volume of documents. That is why there is no generic price. In a conversation, it is possible to set the scope of your case before any estimate.
Can you give an example of due diligence?
Before buying a company, the investigation reveals a significant employment claim and a supply contract with a high termination penalty. With this in hand, the buyer negotiates a discount on the price and a clause that makes the seller liable for that liability. The risk did not disappear, but it stopped being a surprise and became a term of the contract, the typical result of well-conducted due diligence.

How the firm works on this subject

The need to check before closing usually translates into the following areas of legal work:

  • Preventive advisory: conducting the legal due diligence, defining the scope, analyzing by area and preparing the risk report.
  • Constitutive and consultative advisory: support for the transaction itself, acquisition, sale, entry of a partner or raising of investment, in light of the findings.
  • Drafting of legal documents: drafting the guarantee clauses, the seller's liability clauses and the contracts that protect the buyer against the risks found.
  • Litigation: when a hidden liability materializes despite everything, the defense of the interests of the party who contracted.

It is with this set that Grisostolo Advocacia is concerned on the legal front of transactions, always in coordination with the accounting and audit professionals the case requires.
