Legal Due Diligence Before Buying a Portuguese Company

A buyer should not acquire a Portuguese company based only on:

• the seller's presentation;
• recent bank statements;
• management accounts;
• a commercial-registry certificate.

Legal due diligence is the process of testing what the company owns, owes, promises and risks before the buyer signs or closes the acquisition.

The objective is not to prove that the company is perfect.

The objective is to identify risk early enough to decide what to do with it.

Start with official company records

Portuguese registry services make important company information available.

A permanent commercial certificate can show:

• company registrations;
• pending registration requests;
• current registered corporate position.

A permanent certificate with documents can also provide electronic documents supporting registered acts, subject to the service scope.

The current articles can be obtained separately.

The annual-accounts certificate gives access to registered annual financial statements.

These sources are a starting point, not the end of due diligence.

Check the company identity

Verify:

• legal name;
• NIPC;
• registered office;
• legal form;
• status;
• object;
• share capital;
• quotas or shares;
• current gerentes or administrators.

A mismatch between the seller's transaction documents and public records needs to be resolved before closing.

Review the articles

The articles can affect:

• quota transfer;
• voting;
• management;
• special rights;
• company representation;
• capital changes;
• shareholder exit.

A buyer of an Lda should not assume standard Companies Code defaults apply unchanged.

Ownership and beneficial ownership

Confirm:

• registered shareholders;
• exact quotas;
• pledges or other registered restrictions;
• shareholder agreements;
• beneficial owner information;
• indirect ownership chains.

The RCBE focuses on natural persons who ultimately own or control the entity.

A share purchase that changes control can require an RCBE update after closing.

Annual accounts

Review historic annual accounts for patterns such as:

• recurring losses;
• unusual liabilities;
• low equity;
• related-party balances;
• shareholder loans;
• material receivables;
• sudden revenue changes.

Financial statements should be analysed by qualified accounting/financial professionals.

The legal team uses them to identify legal questions and transaction risk.

Shareholder loans

A company can owe significant money to the seller separately from the value of the quotas.

Map:

• principal;
• interest;
• maturity;
• documentation;
• repayment history;
• accounting treatment.

If the transaction ignores shareholder debt, the buyer can acquire the company while the seller remains a creditor.

Bank debt and guarantees

Request information about:

• loans;
• credit lines;
• mortgages;
• pledges;
• personal guarantees;
• company guarantees for third parties;
• covenant breaches.

Check whether the acquisition triggers lender consent or change-of-control consequences.

Key customer and supplier contracts

Review contracts that materially affect business value.

Focus on:

• duration;
• automatic renewal;
• termination;
• assignment;
• change-of-control;
• exclusivity;
• minimum purchase;
• pricing;
• penalties;
• service levels;
• liability caps.

A business whose main customer can terminate immediately after acquisition may be worth much less than the headline price suggests.

Employees

Employment due diligence should cover:

• employee list;
• contracts;
• salary;
• bonuses;
• working time;
• overtime;
• holiday;
• remote work;
• fixed-term status;
• disciplinary cases;
• harassment/discrimination complaints;
• dismissals;
• pending disputes.

Also identify key employees whose departure would materially affect business value.

Contractors and false self-employment risk

A person invoicing the company is not automatically an independent contractor for labour-law purposes.

Review long-term contractor relationships where the facts may resemble employment.

A buyer can inherit the consequences through ownership of the company.

Litigation and claims

Ask for:

• pending court cases;
• threatened claims;
• settlement negotiations;
• administrative proceedings;
• enforcement actions;
• customer complaints with significant exposure.

Do not limit the review to cases the seller considers "material".

Materiality should be defined for the transaction.

Tax

Tax due diligence needs its own qualified tax analysis.

Legal due diligence should still identify:

• outstanding tax disputes;
• tax payment plans;
• liens/security;
• historic restructurings;
• shareholder transactions;
• cross-border arrangements.

Do not treat a tax-clearance certificate as a substitute for full tax due diligence.

Property and leases

If the company owns or leases premises, review:

• title or lease;
• term;
• rent;
• deposits;
• renewal;
• termination;
• use;
• licences;
• landlord consent/change-of-control provisions;
• construction or compliance issues.

Business value can depend on remaining in a particular location.

Intellectual property

Identify who owns:

• trade marks;
• software;
• source code;
• domain names;
• designs;
• databases;
• content;
• know-how.

Check whether IP created by:

• founders;
• employees;
• freelancers;
• agencies

was actually assigned to the company.

Do not assume the company owns software because it paid the developer.

Data protection

Review:

• privacy notices;
• customer databases;
• processors;
• international transfers;
• data breaches;
• direct marketing;
• employee data.

Data-protection liabilities can remain with the company after a share acquisition.

Licences and regulated activities

Confirm which permits or registrations the business needs.

Ask:

• are they current?
• are they held by the correct entity?
• does change of control require approval?
• are there pending sanctions?

A business that cannot legally operate after closing is not a functioning acquisition.

Related-party transactions

Look for business with:

• shareholders;
• gerentes;
• family members;
• affiliated companies.

Review:

• pricing;
• loans;
• asset use;
• service agreements;
• guarantees.

Related-party arrangements often change when the seller leaves.

What should the due diligence report do?

A useful DD report should classify issues.

For example:

Red

Potential transaction blocker or major liability.

Amber

Risk requiring price, contractual protection, condition or remediation.

Green

No material issue identified on the documents reviewed.

The report should connect each risk to an action.

A list of documents is not enough.

How due diligence changes the transaction

A DD finding can lead to:

• lower price;
• deferred price;
• escrow;
• retention;
• condition precedent;
• specific warranty;
• specific indemnity;
• covenant to fix an issue;
• seller document at closing;
• decision not to proceed.

This is why due diligence should be completed before the purchase agreement becomes economically irreversible.

Due diligence does not eliminate risk

No legal review can guarantee that a company has no undisclosed problem.

Due diligence is limited by:

• records available;
• seller disclosure;
• public information;
• agreed scope;
• time;
• materiality threshold.

The contract should therefore work together with due diligence.

Warranties and indemnities allocate residual risk that investigation cannot eliminate.

Frequently asked questions

Can I do due diligence from public records only?

No. Public records are important, but many contractual, employment, regulatory and operational liabilities require seller documents and explanations.

Can annual accounts prove the company has no hidden debt?

No.

Should due diligence happen before the SPA?

Ideally before the SPA becomes unconditional. The transaction can use staged signing and conditions depending on the deal.

What if due diligence finds a problem?

The buyer can negotiate price, conditions, warranties, indemnities, remediation or exit.

Is legal due diligence the same as financial due diligence?

No. They overlap but use different expertise and objectives.

Does a clean DD report guarantee there are no liabilities?

No. It reduces uncertainty and structures residual risk.
