What a Commercial Lawyer in Lisbon Does

Let me explain this in a very practical way, as if we were sitting together and you were asking me what I actually do for clients on a day-to-day basis.

As a commercial lawyer in Lisbon, my role is to help businesses operate, grow, and protect themselves legally in Portugal. That means translating Portuguese commercial law into clear, actionable advice you can rely on — whether you’re starting a company, negotiating a contract, expanding into the Portuguese market, or restructuring an existing business.

Lisbon is a dynamic business hub, especially for startups, international investors, and cross-border companies. Because of this, commercial legal work here often combines Portuguese corporate law, EU regulations, and international business standards. My job is to make sure all of these layers work for you — not against you.

At a high level, my work focuses on six core areas:

1. Corporate formation & business structuring in Lisbon

I assist with:

  • Setting up Portuguese companies (Lda, SA, branches, subsidiaries)
  • Choosing the right corporate structure for tax, liability, and growth
  • Drafting articles of association and shareholders’ agreements
  • Advising foreign investors entering the Portuguese market

2. Commercial contracts & contract negotiation

This includes:

  • Commercial contracts and service agreements
  • Distribution and agency agreements
  • Partnership and joint venture agreements
  • NDAs and confidentiality agreements
  • Terms & conditions for Portuguese and international clients

3. Distribution, agency & commercial expansion

My work includes:

  • Drafting and reviewing distribution agreements
  • Advising on commercial agency law in Portugal
  • Compliance with EU competition and exclusivity rules
  • Termination and compensation risks for agents and distributors

4. Mergers, acquisitions & corporate transactions

This includes:

  • Legal due diligence on Portuguese target companies
  • Share purchase and asset purchase agreements
  • Corporate restructuring and shareholder exits
  • Cross-border transactions involving EU entities

5. Data protection & compliance

  • GDPR compliance for commercial activities
  • Data protection clauses in commercial contracts
  • Privacy policies and internal compliance frameworks
  • Risk assessment for data handling in Portugal

6. Ongoing compliance & dispute prevention

  • Ongoing legal advice for Portuguese companies
  • Reviewing business practices for compliance risks
  • Advising on contract breaches and early dispute resolution
  • Preparing companies for litigation or arbitration if needed

In simple terms

When you work with me as your commercial lawyer in Lisbon, my goal is to: Protect your business legally under Portuguese law, help you make confident commercial decisions, reduce risk while supporting growth, and act as a long-term legal partner.

Everything I do is focused on practical, business-oriented legal advice — not unnecessary complexity.

Typical Clients

Who I Help

Let me briefly explain who usually comes to me and how I help — in a very straightforward, practical way. I’m Clara, a commercial lawyer in Lisbon with over 10 years of experience advising businesses operating in Portugal.

Startups & early-stage companies

Typically, they need help setting up the right company structure, drafting shareholder agreements, and putting solid commercial contracts in place from day one.

Example:

A tech startup needed to onboard its first strategic partner. I helped structure the partnership agreement so the founders retained control while still attracting growth opportunities.

SMEs & growing businesses

Small and medium-sized companies often come to me once their operations become more complex, involving ongoing contracts and distribution agreements.

Example:

An established Portuguese SME wanted to renegotiate supplier contracts to reduce liability and improve termination protections.

International investors & foreign companies

They need a commercial lawyer in Lisbon who understands both Portuguese law and cross-border business realities.

Example:

An EU-based company opening a branch needed advice on setup and local compliance. I guided them so they could start quickly.

Portuguese branches, distributors & agents

Portuguese law is very specific, especially when it comes to termination and compensation risks for agents and distributors.

Example:

A foreign company wanted to terminate an agent. I assessed the risks and structured an exit strategy that avoided disputes.

Exporters & importers

Commercial legal support related to contracts, liability allocation, and risk management under Portuguese and EU rules.

Example:

A Lisbon-based exporter needed stronger international sales contracts to better protect them in cross-border transactions.

Direct Answers

Frequently Asked Questions

Below are some of the most common questions I’m asked by clients looking for a commercial lawyer in Lisbon. I’ve answered these the same way I do in practice — clearly, honestly, and based on over 10 years of hands-on experience.

1. How long does it take to set up a company in Portugal?

In most straightforward cases, a Portuguese company can be incorporated in a few business days. However, the real timeline depends on the structure you need, shareholder arrangements, and whether there are foreign investors involved.

With my experience advising startups and international clients in Lisbon, I make sure the company is not just formed quickly — but formed correctly, so you don’t face legal issues later.

2. Do commercial contracts need to be in Portuguese?

Legally, contracts can be in English. That said, Portuguese-language versions are often essential for enforceability, regulatory matters, or court proceedings. Based on my experience, I usually recommend:

  • Bilingual contracts for international businesses
  • Portuguese governing law clauses where appropriate

This approach protects you if the contract ever needs to be enforced in Portugal.

3. What are the most common mistakes businesses make?

The most common issues I see are:

  • Using foreign templates that don’t comply with Portuguese law
  • Weak termination and liability clauses
  • Ignoring mandatory rules on agency and distribution

After more than a decade as a commercial lawyer, I can tell you these mistakes are costly but avoidable with proper legal advice upfront.

4. How much does a commercial lawyer in Lisbon cost?

It depends on the type of work. For many services, I offer clear fixed fees (such as contract reviews, NDAs, or company formation support). For more complex matters, I explain hourly rates or retainers in advance.

Transparency is a key trust principle for me — you will always know the cost before any work starts.

5. Do I need a local lawyer if my business is international?

Yes, and this is something international clients often underestimate. Portuguese commercial law has specific mandatory rules, especially around contracts, agency relationships, and corporate governance. My role is to bridge the gap between international business expectations and local legal reality — something I’ve done consistently throughout my career.

6. How are commercial disputes usually resolved in Portugal?

Most commercial disputes are resolved before reaching court, through negotiation or settlement. When disputes do arise, they can be handled through Portuguese courts or Arbitration (often faster and confidential).

With my experience in dispute prevention and litigation readiness, I focus on protecting your position early, so escalation is a last resort — not the first.

7. Are NDAs and confidentiality agreements enforceable?

Yes, NDAs are enforceable, but only if they are properly drafted under Portuguese law. I regularly draft and review NDAs to ensure a clear scope of confidential information, proportionate penalties, and enforceability before Portuguese courts. This is a good example of where expertise matters more than templates.

8. What legal risks should I consider when appointing a distributor?

This is a high-risk area if not handled correctly. Portuguese law gives strong protection to commercial agents, particularly regarding termination compensation. I’ve advised many clients on structuring these relationships to minimize long-term financial exposure while remaining legally compliant.

9. Why should I work with you instead of a general practice lawyer?

Commercial law is my core focus. With over 10 years of experience, I understand not just the law, but how businesses actually operate. Clients work with me because I:

  • Specialize in commercial and corporate matters
  • Explain legal issues in plain language
  • Provide practical, business-oriented solutions
  • Build long-term, trust-based relationships

"If you’re looking for a commercial lawyer in Lisbon who combines experience, expertise, and clear communication, this is exactly how I work."
