Transfer of shares: how to buy or sell an Lda in Portugal

The transfer of shares is the transmission — total or partial — of the participations in a limited liability company (Lda). The company retains its legal personality and NIF; what changes is who is a partner and in what percentage. In Portugal, it is one of the most common ways to buy or sell an SME without 'starting from scratch'.

In this guide, you will find a clear definition, the difference compared to business transfer, the typical steps to buy or sell shares, a checklist of documents and formalities, and what to ask the accountant or lawyer before signing. If you already know what you are looking for, you can explore businesses for sale or advertise the sale confidentially on the ComprarEmpresa marketplace.

What is the transfer of shares?

The transfer of shares is the transmission of the ownership of the shares of a limited liability company (Lda): the transferee becomes a partner (or increases their participation) and the transferor ceases to be one or reduces their share. The corporate vehicle — the Lda — remains the same; what changes is the composition of the share capital.

A limited liability company (Lda) is the most commonly used corporate type by SMEs in Portugal: liability is typically limited to the company's assets, capital is divided into shares, and there are specific rules for transmission in the articles and in law. In this article, 'Lda' and 'limited liability company' refer to this vehicle — there is no separate guide solely about LLCs.

In practice, the transfer can be:

• Total — the entirety of the shares is transferred (or the effective control of the company), which in common language many call 'selling the company'.

• Partial — only a fraction is transferred; new partners join or the capital is redistributed among the existing ones.

It is also important to distinguish the dynamics in a single-member (one partner) and in a multi-member (two or more). The concept of transferring shares is the same; what changes is the governance, any rights of first refusal, consents, and how the exit or entry is negotiated. Always handle the specific case with a lawyer — without assuming that 'single-member = simpler' in all aspects.

Transfer of shares vs 'selling the company' in common language

In everyday conversation, 'selling the company' can mean various things: transferring the shares of the Lda, transferring the establishment, or even transferring the operation without alienating the company. Legally and economically, they are not equivalent. If the goal is to transfer the partner's position — and with it the control of the legal entity — you are in the realm of the transfer of shares. If the goal is to transfer the commercial establishment without assuming the company, the typical route is the business transfer (see next section).

In the marketplace and in advertisements, it is common to see phrases like 'transfer of shares' or 'sale of shares'. Treat them as a sign of intent: always confirm the legal structure of the transaction with professionals before proceeding.

Business transfer vs transfer of shares: what is the difference?

The central difference is the object of the transmission: in a business transfer, the establishment (the operating business) is typically transferred; in the transfer of shares, the partner's position in the company is transferred. Risks, liabilities, NIF, leases, and taxation may diverge — and the wrong choice can be costly.

Practical comparison (high level; the specific case dictates):

• Object — business transfer: establishment / assets and operation agreement; transfer of shares: participations in the Lda.

• NIF and history — business transfer: the buyer can operate with another legal entity or structure; transfer: the same company (same NIF) continues, with new partners.

• Liabilities — business transfer: the focus is on what is transferred in the agreement; transfer: the company retains its liabilities — the buyer 'enters' into that reality.

• Leases and licenses — in a business transfer, there are specific rules and practices of the establishment; in the transfer, contracts and licenses of the company typically remain with the legal entity (with change of control clauses to verify).

• Employees — in both scenarios, there are labour implications to analyse with a lawyer; the mechanics and scope differ depending on the structure.

• When it makes sense — business transfer: you want the business without inheriting the company; transfer: you want the Lda (corporate brand, contracts, history, licenses of the legal entity) and are willing to manage what comes with it.

For the complete contrast and use cases, read the guide business transfer vs company purchase and explore the hub of business transfer. Do not copy the decision from a generic article: seek professional advice on the structure you are negotiating.

Note: assignment of operation is not the same as assignment of shares. The assignment of operation relates to the operation of the establishment; the assignment of shares changes the ownership of the company. The article on business transfer vs purchase already delves into this contrast — use it as a reference and validate the framework with your lawyer.

How to buy an Lda by assignment of shares

Buying an Lda by assignment of shares means acquiring (totally or partially) the partner's position in the existing company: you take on the vehicle, the NIF, and, as a rule, the assets and liabilities of the legal entity — hence the importance of serious due diligence before signing.

What the buyer acquires (and what they inherit)

In general terms, the assignee becomes a partner in the same company. This implies, in the typical logic of the operation:

• Acquires — shares (percentage of capital), associated social rights and, if applicable, control of management according to the agreement and the law.

• ‘Inherits’ in the practical sense — the company remains responsible for its liabilities, contracts, employment relationships and contingencies. The buyer does not ‘clean’ the past just by changing partners.

• Remains — NIF, registration history and, in many cases, contracts and licenses of the legal entity (subject to clauses and authorisations).

Details of personal liability of the transferring or acquiring partner, guarantees and indemnity clauses: validate with a lawyer. Do not assume that ‘buying shares = zero historical risk’.

Typical steps (high level)

The specific process depends on the agreement, the number of partners and the operation. At a high level, the path usually follows:

1. Interest and alignment — clarify what is being purchased (total or partial shares) and what is expected from the business.

2. Confidentiality — NDA or equivalent before sharing sensitive information.

3. Due diligence — financial, tax, legal, labour and operational analysis of the company.

4. Negotiation — price, conditions, timeline, guarantees; possible CPCV or preparatory agreement, if applicable.

5. Formalisation of the assignment — appropriate document for the transfer of shares, with professional support.

6. Registrations and updates — commercial registration and other updates (AT and other entities, as applicable).

Specific due diligence on shares

When buying shares, the diligence weighs on the entire company: corporate structure, tax and labour contingencies, disputes, shareholder agreements and change of control clauses. It is not enough to look at the turnover of the month.

Use the due diligence checklist for buying a company as a basis and ask the accountant and lawyer for a plan tailored to the specific Lda. Especially reinforce the corporate axis (certificate, agreement, minutes) and the tax/labour — areas where post-signature surprises are most costly.

How to sell shares of your Lda

Selling shares of your Lda is transferring, totally or partially, your stake to a buyer — with documentary preparation, clarity on preferences and corporate consents, and a discreet process to find qualified counterparts.

Prepare the company and the dossier

The more organised the folder is, the faster and more credible the process runs. As a rule, prepare:

• Updated permanent certificate and current social agreement.

• Recent, coherent and explainable financial statements and information.

• Situation with the Tax Authority and Social Security.

• Key contracts, staff map and note on disputes or contingencies.

For the complete sell-side angle, follow preparing the company for sale and the guide steps to sell a company. If you need to frame value, the tips for assessing the value of a company and the page of company valuations help — without replacing a professional.

Shareholder preferences and consents

In multi-person companies (and sometimes even in scenarios with specific agreements), there may be pre-emption rights, consent requirements or other restrictions on the transfer of shares provided for in the articles of association or by law. Do not proceed based on 'gut feelings': check the articles and the Companies Code with your lawyer before negotiating or announcing internally.

Ignoring preferences or consents is one of the most costly mistakes on the seller's side — it can invalidate or delay the transaction and generate disputes among shareholders.

Confidentiality and qualified buyers

Selling shares without revealing the identity of the company to curious parties or competitors requires a discreet funnel: initial anonymisation, buyer qualification, and sharing of information under confidentiality. This is precisely the model of the marketplace BuyCompany.

To advertise discreetly, use sell company and see how it works the process. The goal is to reach serious buyers without exposing the transaction in the open market.

Documents and formalities (practical checklist)

Before signing a share transfer, the buyer and seller must gather (and cross-check) a minimum set of documents. The list below is a practical starting point — adapt it to the sector and validate formalities with a lawyer and accountant. Do not invent official deadlines or fees: confirm them from official sources and with your professionals.

• Updated permanent certificate of commercial registration.

• Articles of association / statutes and relevant amendments.

• Minutes and resolutions affecting the transfer or governance.

• Any shareholders' agreements or partnership pacts.

• Recent financial statements (and, if possible, a history of several years).

• Regularised (or clarified) situation with the Tax Authority.

• Contributory situation with Social Security.

• Key contracts with clients, suppliers, and partners (including change of control clauses).

• Lease agreement and conditions of the premises, if applicable.

• Licences, permits, and authorisations necessary for the activity.

• Staff map: contracts, categories, seniority, and relevant labour liabilities.

• Note on disputes, processes, or known contingencies.

• Identification of shareholders and the percentage of shares subject to the transfer.

• Document formalising the transfer (appropriate draft and form — to be validated with a lawyer).

• Commercial registration plan and subsequent updates (Tax Authority and other entities, as applicable).

The typical formalisation involves a document suitable for the transfer of shares and the necessary registrations/updates to ensure ownership is reflected to third parties. Do not use generic templates from the internet without professional review. For the buyer's due diligence side, complement with the due diligence checklist.

Taxes and costs: what to ask the professional

There is no single and universal answer to 'how much is paid' in a share transfer: the tax implications and costs depend on the transaction, the parties, and the company's assets. Instead of invented percentages, take a clear set of questions to the accountant or tax lawyer.

Useful questions to ask the professional:

• What are the tax implications of the transfer for the seller (for example, treatment of capital gains), in my specific case?

• Are there relevant implications for the buyer in this structure?

• Does the company's assets include real estate or assets that alter the framework (for example, IMT in specific scenarios)?

• Could there be Stamp Duty or other charges associated with the document or registration?

• What commercial registration and advisory (lawyer, accountant) costs should I budget for?

• Are there declarative obligations or updates with the Tax Authority after the transfer?

Common mistakes (buyer and seller)

Even with good intentions, there are recurring mistakes in share transfers — and the checklist and due diligence help to avoid them.

• Confusing lease transfer with share transfer — different objects, risks and taxation; choose the structure with professionals.

• Skip the due diligence — buying shares without analysing the company means inheriting surprises (liabilities, litigation, dependencies).

• Ignore partner preferences or consents — this can block or invalidate the transaction; check the agreement and law with a lawyer.

• Only rely on verbal agreements — promises made during negotiations should be included in the appropriate document (statements, warranties, conditions).

• Underestimate hidden liabilities — tax, labour and contingencies weigh especially when acquiring the company.

• Expose the sale without confidentiality — announcing without discretion can affect clients, employees and competitors.

• Fail to align records and updates — the transfer does not 'end' at signing; confirm the registration plan with your lawyer.

Frequently asked questions about share transfers

What is a share transfer?

It is the total or partial transfer of shares (quotas) in a limited liability company (Lda). The company retains its legal personality and tax identification number; ownership changes — who is a partner and in what percentage. Do not confuse with the transfer of a business or with the assignment of exploitation.

What is the difference between a transfer and a share transfer?

In a transfer, the business (assets and exploitation agreement) is typically transferred; in a share transfer, the partner's position in the company is transferred. Risks, liabilities and taxation may differ. Consult the guide on transfer vs buying companies and validate the specific case with professionals.

How to buy an Lda company through a share transfer?

In general terms: align interests and confidentiality, analyse the company (due diligence), negotiate price and conditions, formalise the transfer and promote the necessary registrations and updates. The specific process depends on the agreement and the transaction — also see how to buy a company.

How to sell the shares of my Lda?

Prepare documentation and valuation, clarify preferences and corporate consents with your lawyer, negotiate with qualified buyers and formalise the transfer with professional support. The marketplace ComprarEmpresa allows to advertise confidentially.

Does the buyer inherit the company's debts?

In the logic of a share transfer, the buyer becomes a partner in the same company — therefore, the company remains responsible for its liabilities. Hence the importance of due diligence. Details of personal liability of the transferring or acquiring partner: validate with a lawyer.

What documents should be requested before a share transfer?

As a rule: permanent certificate, articles of association, recent accounts, status with the tax authority and social security, relevant contracts, labour information and litigation. Complete with the due diligence checklist from the website and with the document checklist from this article.

Is a share transfer in a sole proprietorship the same as in a multi-person company?

The concept (transferring shares) is the same, but the dynamics of consents, preferences and governance change with the number of partners and the agreement. Treat each case with professionals — do not assume shortcuts just because the company is a sole proprietorship.

What taxes are paid in a share transfer?

There may be tax implications for the seller and, in some cases, for the buyer, depending on the transaction and the company's assets. There is no single answer in this article — confirm with an accountant or tax lawyer before closing.

When should you prefer a transfer instead of a share transfer?

When the goal is to acquire the business without assuming the company (or vice versa, if the company is precisely what you want). The choice depends on risk, contracts (for example, leases), licenses and taxation — see the comparative article and the hub on transfers, and seek advice.

Is a share transfer the same as M&A?

‘M&A’ is the broad term for mergers and acquisitions; a share transfer is a common way to acquire or sell SMEs in Portugal. This guide focuses on the mechanics of Lda in the marketplace, not large-scale operations or private equity.

Next step

To recap: a share transfer conveys the partner's position in the Lda; a transfer typically conveys the business; the choice of structure and due diligence should be done with professionals. If you want to buy, see businesses for sale. If you want to sell shares discreetly, advertise the sale. For confidential support, contact the team or create an account on the marketplace.
