Legal Text Excerpt (C1)

Legal Portuguese is the most stable register of the language. It preserves grammatical forms that have been in continuous use since the sixteenth century — mesoclisis, the future subjunctive, the synthetic future indicative — and it wraps simple provisions in heavily nominalized, passive-voiced, cross-referenced prose. For a C1 learner, legal texts are often the first genuine encounter with high-register formal Portuguese, and the forms found here appear throughout government documents, rental contracts, employment agreements, privacy policies, and the Portuguese Constitution itself.

This page presents an original contract clause in the style of a rental or service agreement, annotates the grammatical features that mark it as legal register, and explains why each form is used where it is. The passage is fictional, but the grammar is exactly what you will encounter in any real Portuguese contract.

The passage

CLÁUSULA SÉTIMA — Incumprimento e Resolução

1. Sempre que se verifique o incumprimento, pelo ARRENDATÁRIO, de qualquer das obrigações estabelecidas nas cláusulas anteriores, e salvo estipulação em contrário expressamente acordada pelas partes, aplicar-se-á o regime previsto no artigo 1083.º do Código Civil, sem prejuízo das demais responsabilidades que, nos termos da lei, daí possam advir.

2. Caso o ARRENDATÁRIO não proceda ao pagamento da renda dentro do prazo estipulado na cláusula terceira, considerar-se-á em mora, nos termos do disposto nos artigos 804.º e seguintes do referido Código, sendo devidos juros de mora à taxa legal, contados a partir do dia imediatamente seguinte àquele em que o pagamento deveria ter sido efectuado.

3. A mora superior a trinta dias, sem que tenha havido regularização integral dos valores em dívida, conferirá ao SENHORIO o direito à resolução do contrato, a qual operará mediante comunicação escrita dirigida ao ARRENDATÁRIO, devendo tal comunicação ser enviada por carta registada com aviso de recepção, sob pena de não produzir os efeitos pretendidos.

4. Se as partes o entenderem, poderá ser celebrado novo acordo destinado a regularizar a situação, o qual ficará sujeito às formalidades previstas na legislação em vigor e só produzirá efeitos a partir da data da sua assinatura por ambas as partes, para todos os efeitos legais.

5. Para todos os efeitos, e nos casos previstos na lei, considerar-se-ão notificações válidas aquelas que forem dirigidas ao domicílio convencional indicado no preâmbulo do presente contrato, salvo se qualquer das partes tiver, entretanto, comunicado à outra alteração do respectivo endereço, por escrito e com a antecedência mínima de quinze dias.

Grammar highlights

1. Mesoclisis as legal-register marker: aplicar-se-á, considerar-se-á, considerar-se-ão

The most visible feature of legal Portuguese is mesoclisis — the placement of a clitic pronoun inside the future or conditional verb form, between the verb stem and the tense ending:

The mesoclitic form decomposes as: verb stem + clitic + tense ending.

Mesoclisis is virtually obligatory in formal written PT-PT when (1) the verb is in the synthetic future or conditional, and (2) nothing preceding the verb triggers proclisis (no não, no que, no fronted adverb, no relative pronoun). In speech, mesoclisis is rare — speakers either use the periphrastic future (vai aplicar-se) or place the clitic proclitically when a trigger is present. But in legal and administrative writing, mesoclisis is the default, and its absence sounds colloquial or ungrammatical.

2. Future subjunctive in contractual conditions: se verifique, se as partes o entenderem, que forem dirigidas, tiver comunicado

Legal and contractual language treats future hypothetical events with a mood that has almost disappeared from modern spoken Portuguese: the future subjunctive. This is the tense of "whenever X may occur," "if the parties should agree," "such events as may arise."

Here se verifique is the present subjunctive (a closely related tense, since sempre que can take either present or future subjunctive; the present is slightly more neutral, the future slightly more legal-archaic). Contrast with:

Entenderem is the future subjunctive (3rd person plural of entender — same stem as the 3rd plural preterite entenderam, minus -am, plus -em). In a se-clause of open future hypothesis, PT-PT legal writing uses the future subjunctive. Everyday speech uses the present indicative (se as partes decidirem... is future subjunctive; se as partes decidem... is present indicative, less formal, and slightly different in meaning).

Forem dirigidas is the future subjunctive of a passive construction — forem (future subjunctive of ser) + past participle dirigidas. This is standard in legal prose: "those which shall be addressed."

Tiver comunicado is the compound future subjunctive: tiver (future subjunctive of ter) + past participle. It expresses a hypothetical future event that will have been completed by the time a later event occurs — "unless [by then] they shall have communicated." Compare Future Subjunctive: Se-Clauses.

3. Normative present subjunctive: sempre que se verifique, caso o arrendatário não proceda, sem que tenha havido

When a legal text states a general norm that triggers conditional on some behavior, the conditional clause often takes the present subjunctive:

Caso is a conjunction equivalent to se in legal register and takes the subjunctive. Sem que introduces a negative circumstantial clause and takes the subjunctive. Sempre que can take either the present or future subjunctive depending on the generality of the reference.

The normative subjunctive signals that the clause describes a type of situation, not a specific event. This is why legal prose is so dense with subjunctives: it is describing classes of circumstances, not particular occurrences.

4. Passive voice as legal-register default: ser enviada, deveria ter sido efectuado, poderá ser celebrado, considerar-se-ão notificações válidas

Legal Portuguese prefers the passive voice. Where ordinary prose would say o senhorio envia a comunicação, legal prose says a comunicação deverá ser enviada. Where ordinary prose would say as partes celebram novo acordo, legal prose says poderá ser celebrado novo acordo.

The passive has three functions in legal writing:

1. Impersonality. It removes the human agent and makes the law itself the active force.
2. Universality. It describes what must or may happen without pinning the obligation on a particular named person.
3. Gravity. The auxiliary-participle structure (ser enviada, ter sido efectuado) sounds weightier than the corresponding active form.

Note the compound passive infinitive ter sido efectuado ("to have been made/effected"). This is a staple of legal Portuguese, used in the conditional (deveria ter sido efectuado) to mark an obligation that was not fulfilled. See Advanced Passive.

5. Legal formulae: fixed expressions that carry legal weight

Portuguese legal writing is built from a stock of fixed phrases that function as conventional units. Their meaning is not fully compositional — each is the traditional way of saying something, and using a near-synonym often sounds wrong.

6. The relative determiner cujo/cuja: às formalidades previstas, do respectivo endereço

Legal Portuguese frequently uses possessive and anaphoric devices that are rare in speech. Cujo/cuja/cujos/cujas ("whose") is standard in formal writing; respectivo ("the respective, their own") functions as a possessive anaphor referring to a previously mentioned party.

See Relative Clauses with cujo.

7. Heavy nominalization: incumprimento, pagamento, regularização, comunicação, notificação, celebração

Legal Portuguese strongly prefers nouns over verbs. Where ordinary language says o arrendatário não cumpriu, legal language says verificou-se o incumprimento por parte do arrendatário. Where ordinary language says o arrendatário não pagou a renda, legal language says o não pagamento da renda por parte do arrendatário.

Note the double complement structure of the nominalization: o incumprimento takes both an agent (pelo arrendatário) and a theme (de qualquer das obrigações). This is how Portuguese nominals preserve argument structure.

The nouns in this passage — incumprimento, pagamento, regularização, comunicação, celebração, assinatura, notificação, alteração — are all deverbal abstract nouns ending in -mento, -ção, or -ura. These suffixes are the factories of legal vocabulary. See Nominalization.

8. Anaphoric reference: o referido Código, nos termos do disposto, o presente contrato, àquele em que

Legal texts build long chains of anaphoric reference — words whose meaning is defined by reference to earlier material in the text.

• o referido Código = "the aforementioned Code" — refers to the Civil Code mentioned earlier in clause 1.
• nos termos do disposto = "under the terms of what is provided for" — o disposto is a participial nominalization meaning "the thing disposed of / provided for".
• o presente contrato = "the present contract" — refers to the contract of which this clause is part.
• àquele em que = "to that [day] on which" — àquele (contraction of a + aquele) picks up the noun dia from earlier in the sentence.

9. Synthetic future indicative: aplicar-se-á, ficará, produzirá, conferirá, poderá

Legal Portuguese uses the synthetic future indicative (aplicará, ficará, produzirá) where everyday language would use ir + infinitive (vai aplicar, vai ficar, vai produzir). The synthetic future has largely retreated from speech, surviving in elevated writing and in some fixed expressions. In legal texts it is the default tense for establishing what will happen:

The synthetic future here does not mean "will" in the predictive sense; it means "shall" in the normative sense — this is what is required to happen.

10. Latinate vocabulary and Latin tags

Portuguese legal vocabulary is heavily Latinate. Some items are naturalized (incumprimento, resolução, mora); others remain quoted as Latin tags:

Juros de mora in the passage is a technical term for default interest — mora preserves its Latin sense of "delay in payment."

Common mistakes

Cultural context

Portuguese contract law is codified primarily in the Civil Code (Código Civil, of 1966, substantially amended), whose drafting established the stylistic baseline for modern Portuguese legal writing. The Urban Lease Regime (Regime do Arrendamento Urbano), now integrated into the Civil Code at articles 1022.º onwards, governs the specific vocabulary used in rental contracts.

The register you see here is not a relic. It is actively produced today by every Portuguese lawyer, notary, and administrative official. Efforts at plain-language reform (linguagem clara) have been ongoing but have not fundamentally displaced this style: consumer-facing contracts must still include clauses drafted in the traditional register to have full legal effect.

Legal Portuguese differs from legal Brazilian Portuguese in several ways — most visibly in mesoclisis (which survives fully in PT-PT legal writing but is rare in BR legal writing, where proclisis or enclisis is preferred even in formal contexts), in orthography (pre-AO90 spellings such as efectuado, recepção, respectivo are often preserved in legal contracts even though the current AO90 standard prescribes efetuado, receção, respetivo), and in lexical choices (e.g., PT-PT arrendamento vs. BR locação for "rental"). The PT-PT legal register is one of the most conservative and traditional registers of any Romance language — and the passage above uses the older spellings to reflect real contractual practice.
