Portuguese law does not set a language for employment contracts, so an English-only contract is not void for being in English. The research we rely on still points the same way: use Portuguese or a bilingual text, and make the Portuguese version the one that controls. A court will want a Portuguese version or an official translation anyway, and your employee has to understand what they sign. This guide covers what the Labour Code actually requires, how to draft a bilingual contract, what changes for contractors and service agreements, and whether you need a registered office in Portugal to hire at all.
TL;DR
- No statute fixes the language of an employment contract in Portugal. The Labour Code regulates written form and content, not language.
- In litigation, courts require a Portuguese version or an official translation, so a Portuguese or bilingual contract is the safe choice.
- Foreign workers from outside the EEA need a written contract with specific particulars, plus a valid residence permit and work authorization before they start.
- Contractor and service agreements follow different rules from employment contracts, so do not reuse one template for both.
- You do not need your own registered office to employ people in Portugal if an Employer of Record (EOR) is the legal employer.

What the law says about contract language
The short version: Portugal has no rule saying an employment contract must be in Portuguese. DLA Piper’s global expansion guide reports no statutory language requirements, and advises drafting in Portuguese or bilingually. It also notes that in litigation, courts require a Portuguese version or an official translation.
That last point is the practical one. A contract can be valid in English and still cost you time and money when a dispute reaches a labor court, because someone has to produce a certified Portuguese text. If you draft in Portuguese from day one, or in two columns, that step disappears.
The Labour Code itself tells the same story. The Portuguese Labour Code, as published by CITE, regulates when a contract must be written and what information it must contain. Article 103 lists the cases that need written form, including fixed-term contracts and contracts with foreign workers. None of the provisions cited there prescribes a language.
So the question is not “is English legal?” It is “which language protects both sides when something goes wrong?” For employment, the answer is almost always Portuguese or both.
When a written contract is mandatory
Many teams assume an English offer letter is enough. In Portugal, some contracts must be in writing, and for those the content is specified.
Two cases come up most for foreign employers:
- Fixed-term contracts. Article 103 of the Labour Code lists these among the contracts that require written form.
- Foreign workers. Under Law no. 7/2009 in the official English translation, Article 5 requires a written contract for a foreign worker or stateless person, with the exception of nationals of an EEA or equal-treatment state.
That written contract must carry specified particulars. They include identification of the parties and their signatures, addresses or head offices, references to the immigration documents, the activities of employer and employee, remuneration, workplace, normal working time, payment terms and dates. The article does not require Portuguese.
A practical checklist for the foreign-worker case:
- Identify both parties with full legal names and addresses or head offices.
- Reference the worker’s immigration document.
- Describe the employer’s activity and the employee’s role.
- State pay, how and when it is paid, the workplace and normal working hours.
- Date and sign it, by both parties.
One more condition sits outside the contract. Non-EU and non-EEA nationals need a valid Portuguese residence permit and work authorization before they begin work, according to the Global Employment Compass for Portugal. A well-drafted contract does not replace that step, and starting work before it is in place creates exposure for the employer.
Portuguese, English or bilingual: how to choose
Three realistic options exist. Which one fits depends on who signs, who reads, and who might one day have to enforce it.
| Option | Works well when | Main risk |
|---|---|---|
| Portuguese only | The employee is a Portuguese speaker and you want the simplest record for a court | Your head office cannot review it without translation |
| English only | Senior international hire, short relationship, internal use | A court will want a Portuguese version or an official translation, which adds time and cost |
| Bilingual, Portuguese controlling | Most foreign-employer situations | Two texts can drift apart if edited separately |
For most foreign companies the third option is the right one. The English text lets your leadership and legal team review the terms. The Portuguese text is the one a court will read. Many providers in this field use bilingual English and Portuguese templates for the same reason.
Write a precedence clause
If you go bilingual, say which version wins. A short clause does the work: both versions are signed, and in case of any difference, the Portuguese version prevails. Without it, a discrepancy becomes an argument about intent. Our recommendation, in line with the guidance above, is to let the Portuguese text govern, since that is the text a Portuguese court will work from.
Keep the two texts locked together
Bilingual contracts fail in the amendments. Someone edits the English paragraph on notice periods and forgets the Portuguese one. Set a rule: no change is valid unless both versions are updated and re-signed, and keep both in one file so they cannot be separated.
Making sure the employee understands what they sign
A signature on a text the employee cannot read is a weak position for the employer. The simple fix is to give them a version in the language they actually work in, and to walk through the key terms before signing: pay, role, working time, place of work, probation, notice and any restrictive clauses.
On the signing mechanics, the Global Employment Compass states that qualified electronic signatures (QES) are recognized in the EU under eIDAS and carry the same legal effect as handwritten signatures for employment contracts in Portugal. That matters for remote onboarding: a new hire in Lisbon can sign a contract issued by a head office abroad without paper moving across borders. Check that the signature method you use is a qualified one, not a simple click-to-accept.
Restrictive clauses deserve extra care in any language. A non-compete, for example, has to meet conditions of its own, and a poorly translated clause is the first one to be challenged. Have such clauses drafted and checked in Portuguese by someone who handles Portuguese employment law.
Contractors and service agreements are a different document
A second source of confusion: people ask about “contract language” when they are actually engaging a freelancer or a company, not hiring an employee. The Global Employment Compass notes that independent contractor and service agreements are distinct from dependent employment contracts, and that their requirements on written form and registration differ.
Two consequences for you:
- Do not stretch a service agreement over an employment reality. If the person works set hours, under your direction, with your tools, a Portuguese authority may look at the substance, whatever the document is called. Talk to a Portuguese employment lawyer before relying on a contractor label for a full-time role.
- Choose the language for a different reason. A B2B service agreement between two companies has more freedom, and English with a Portuguese governing-law clause is common. The same logic about enforcement still applies: if a dispute lands in a Portuguese court, expect to need a Portuguese version or official translation.
If you have a long-term person embedded in your team, the employment route, directly or via an EOR, is the cleaner way. Our guide to remote work in Portugal for a foreign company explains how those arrangements work in practice.
Do you need a registered office in Portugal to hire?
This is the other question readers attach to contract language, and the answer depends on how you hire.
If you employ the person yourself, you are the employer under Portuguese law, with registration, tax and social security duties in Portugal. In practice that means a local presence of some kind, whether a company, a branch or a registration that lets you run payroll and file. Setting that up takes time and ongoing administration.
If you use an Employer of Record, the EOR is the legal employer. It signs the employment contract, runs payroll, pays social security and handles compliance, and you direct the day-to-day work. No entity of yours is needed in Portugal. This is the route most foreign companies take for a first hire or a market test.
The EOR arrangement also changes your contract question. The employment contract is between the employee and the EOR, drafted to Portuguese law, while your company signs a services agreement with the EOR. That gives you two documents with two sets of language choices:
- The employment contract: Portuguese or bilingual with Portuguese controlling.
- The services agreement with your provider: usually English, with clear scope and responsibilities.
For a broader view of the legal duties around hiring, see our compliance checklist for hiring in Portugal, and for the choice between the two models, EOR versus entity setup.
A quick drafting routine for foreign employers
This is the process we suggest for any new Portugal hire:
- Decide the model. Direct employment through your own entity, or an EOR as legal employer.
- Check the worker’s status. EU or EEA national, or someone who needs a residence permit and work authorization first.
- Pick the contract type. Fixed-term and foreign-worker contracts must be written, so plan the full text early.
- Draft in Portuguese, with an English reference text and a precedence clause.
- Review key terms with the employee in the language they use at work.
- Sign with a qualified electronic signature or by hand, and store both versions together.
- Control amendments. Update both languages at the same time and re-sign.
A team that follows these steps rarely meets a language problem. The trouble starts when an English offer letter, a Portuguese payroll record and a head-office handbook each say something slightly different.
Our perspective
Most of the contract problems we see do not come from the law. They come from a gap between what the foreign head office believes it signed and what exists in Portuguese on file.
Portugal’s rules on language are lenient, and that is exactly why companies get careless. English-only works until the day someone needs to enforce it, change it or explain it to an inspector. We prefer to fix that at the start: a Portuguese contract, an English reference text, a clear precedence clause, and a payroll record that matches both.
That is also why we think an EOR is the sensible first step for most international companies. The contract is drafted under Portuguese employment law by people who work with it daily, you do not have to maintain an entity while you test the market, and onboarding moves fast. When a team is ready to build a permanent presence, we support entity setup as well, so the contracts move across without starting from scratch.
If you are unsure about a clause, ask before you sign. It costs far less than fixing it afterward.

Common mistakes to avoid
- Using a home-country template. An at-will style contract or a template from another jurisdiction does not fit Portuguese rules on written form, content and termination.
- Skipping the precedence clause. Two languages with no hierarchy invite a dispute.
- Starting before work authorization. A non-EEA hire needs a valid residence permit and work authorization before commencing employment.
- Mixing up contractor and employee paperwork. The two documents follow different requirements.
- Unqualified e-signatures. Use a qualified electronic signature where you want the same effect as a handwritten one.
- Forgetting amendments. Updating one language only leaves you with two contracts.

FAQ
Does an employment contract in Portugal have to be in Portuguese?
No statute requires it. The Labour Code regulates when a contract must be written and what it must contain, not the language. Professional guidance still recommends Portuguese or bilingual drafting, because courts require a Portuguese version or an official translation in litigation.
Can I use an English-only contract for a Portuguese employee?
It is not prohibited, but it is not the safest choice. The employee must understand what they sign, and any dispute will need a Portuguese text. A bilingual contract with the Portuguese version controlling gives your head office a readable copy and gives a court the version it expects.
Which version applies if the Portuguese and English texts differ?
The one your contract says applies. Add a clause stating that the Portuguese version prevails in case of difference. We recommend this because Portuguese courts work from the Portuguese text, and it removes any argument about which wording reflects the parties’ intent.
Do I need a registered office in Portugal to hire someone there?
Not if you hire through an Employer of Record, which acts as the legal employer and handles contracts, payroll and compliance. If you employ directly, you take on the employer’s registration, tax and social security duties in Portugal, which in practice calls for a local presence. Ask a Portuguese adviser which form suits your plans.
Are contractor agreements subject to the same language rules?
They are distinct from employment contracts, and their requirements on written form and registration differ. Business-to-business agreements usually allow more freedom in choosing the language. Make sure the role is really a contractor role, since the substance of the work matters more than the label on the document.
