Why Legal Support Is Essential in M&A Transactions

Without an in-depth legal analysis (due diligence), you risk uncovering hidden liabilities, disputes, or legal defects that can significantly increase the cost of the transaction or completely change its purpose. Poorly set contractual terms, warranties, and claims for defective performance may also create legal or financial burdens for you in the future.

That is why the attorneys at ARROWS, a Prague-based law firm, provide comprehensive legal protection. They cover the entire process—from preparing the business model, through reviewing the counterparty, to closing the transaction and post-closing administration. Their services also include structuring the deal, contract negotiations, communication with regulators, and legal support in the event of disputes.

Why are transactions and M&A legally risky?

A transaction is not just signing a piece of paper. It is a set of legal, tax, financial, and operational decisions that affect one another. The common risk starts as early as the review of the transaction target and the counterparty (so-called due diligence). Buyers often think they know the company or asset they want to acquire. In reality, however, things are often more complex—for example due to historical contracts or unresolved disputes.

Hidden court proceedings, unpaid tax or social security arrears, mortgages, or liens—any of these can later become your problem. The attorneys at ARROWS, a Prague-based law firm, identify these risks in advance during the review phase, before you commit to the transaction.

The second significant risk is the structuring of the transaction itself. To set an appropriate structure (asset deal vs. share deal, merger, etc.), company sales and transaction advisory is often used in practice as well, so that the impacts on liability and taxes are predictable. A simple share sale, asset sale, merger, or acquisition—each form has different tax implications, a different scope of the seller’s liability, and different legal consequences.

Choosing the structure is not a matter of intuition, but of thorough legal and tax analysis. Incorrect structuring can burden you with high tax liabilities or leave you in a position where you have unintentionally assumed liability for past breaches of law.

The third layer involves contractual terms and warranties. Sellers and buyers naturally have different interests: the seller wants to minimize future liabilities, while the buyer seeks the broadest possible right to compensation.

If it later turns out that matters were not presented correctly, negotiating terms without an expert often puts you at a disadvantage. Mistakes such as an improperly set warranty, a short period for notifying defects, or a low liability cap are difficult to fix later. The practical links between warranties, liability, and the setup of contractual relationships within a group are also discussed in the recent article Dispute prevention in a holding: Setting contractual relationships between related companies.

The fourth factor is the legal status and the asset itself. Does the seller have the right to sell what they promise? Are there easements that should be settled, or legal obstacles preventing the transfer?

In the Czech Republic and in cross-border transactions, surprises often appear in the Real Estate Cadastre, commercial registers, or with supervisory authorities. The attorneys at ARROWS, a Prague-based law firm, systematically verify these matters and communicate with the relevant authorities, thereby eliminating potential risks.

How does ARROWS, a Prague-based law firm, protect investors and buyers?

Phase 1: Review and analysis

The attorneys at ARROWS, a Prague-based law firm, work with a set of questions and templates (a data room) to ensure they review:

• Ownership and legal title
• History of court proceedings and their status
• Existence of contracts and their terms
• Tax and regulatory obligations
• Employment-law matters and obligations towards employees
• Insurance coverage and insurance risks
• Compliance with legal regulations (compliance)

This review is referred to as due diligence and is a key element of protection. We are attorneys at ARROWS, a Prague-based law firm registered with the Czech Bar Association and insured for damages up to CZK 400,000,000—this enables us to undertake and handle even complex, high-value transactions.

Phase 2: Structuring and legal advice

After completing the review, we will propose and discuss with you a tax- and legally optimal structure. For example:

• Whether it is more appropriate to purchase individual assets or the entire company (ownership interests/shares)
• What tax implications the chosen route has
• How to minimize the buyer’s liability for historical debts

At this stage, the attorneys from ARROWS, a Prague-based law firm, often work with tax advisors to ensure that the structure is set up in the most advantageous way possible for you.

Phase 3: Contract negotiations and closing

Contract negotiations are both an art and a science. You need to know what you can negotiate hard on and where compromise is necessary. The attorneys at ARROWS, a Prague-based law firm, will ensure that:

• Representations and warranties are clearly defined and relate to real risks.
• Defect notification periods and deadlines are realistic.
• Liability caps are contractually set.
• Escrow or custody arrangements are properly set up in an account that then serves to cover any potential claims.

Without these elements, you are in a position where you cannot exert sufficient pressure on the seller to honor their warranties.

Phase 4: Post-closing management

Even after the transaction is closed, disputes may arise. The buyer may suddenly discover that performance is not as promised, or that a hidden debt has emerged.

At that moment, it is crucial to have properly prepared documentation, contractual wording, and evidence. The attorneys from ARROWS, a Prague-based law firm, will represent you at this time in negotiations with the seller and, if necessary, in court in the Czech Republic.

When exactly do you need legal support from ARROWS?

The answer is simple: from the very beginning. Sometimes we meet clients who think they only need a lawyer in the final stage, when the contract is almost ready. However, that is a fundamental mistake.

A lawyer should be part of the team already when planning the transaction, during initial negotiations, and certainly when conducting due diligence on the counterparty. If you are already at an advanced stage and do not have a lawyer, we recommend contacting ARROWS, a Prague-based law firm, without delay. The second-best time is now.

Final summary

Transactions and M&A are not merely a business matter – above all, they are a legal and financial operation with lasting consequences. Without qualified legal support, you risk:

• Hidden legal defects and debts that may burden you for months or years after closing
• Tax surprises and unexpected liabilities
• Contractually insufficiently secured compensation claims if it later turns out that things are not in order
• Lengthy and financially costly court disputes over enforcement of rights

The attorneys from ARROWS, a Prague-based law firm, will ensure that every phase of the transaction is properly covered from a legal perspective, that risks are identified in advance, and that your investment and your rights are protected.
